Equipment for laying crumb rubber. Automatic crumb rubber spreader Mechanical rubber spreader

Description

The advantage when using special equipment is obvious. The technique is easy to use and maintain, the machine setting allows you to avoid the waste of components and produce a product of a given thickness and quality. The use of the machine allows you to reduce the number of attendants (on average, a team of specialists up to 3-5 people is required: 2 on the machine and 1-3 auxiliary workers preparing the mixture). At the same time, labor productivity is several times higher than that of a non-mechanized team, at least 1000 m2 / day. During the participation of a manufacturing company in an open competition (tender), technical equipment plays a far from unimportant role in determining the winner by the organizers. Characteristics: 1. Filling width: 2500 mm 2. Travel speed: 0.8-6 m/min. 3. Pouring capacity: 100-500m/hour 4. Power: 8kw 5. Weight: 850kg. 6. Dimensions: (L*W*H) 3000*1800*720 mm. Description of the machine: 1. Work area: with steel flat surface with anti-corrosion coating, can work in harsh environment. 2. Front scraper: Steel structure, the distance to the ground can be manually adjusted by screw, which allows you to set the thickness of the coating. With the help of the upper limiter, the width can be adjusted. 3. Control and working movement device: based on chain transmission. It has a speed control, it can move forward, backward and along a curve. 4. Device for movement: if necessary, move the machine, on wheels. A hydraulic cylinder lifts the work surface off the tracks for manual movement. Pressure plate: has 4 functions: height setting, angle setting, temperature setting and vibration setting. The mixture is leveled with a plate after vibration, pressing and smoothing. Vibration is essential for proper compaction of the material, and heating up to 80°C provides more fast setting and hardening the surface and improving the quality of the coating. Fields of use and products obtained: The products of this equipment are seamless rubber crumb coatings, which are laid as a solid carpet on a hard or prepared surface. Basically, the coating is laid on playgrounds and sports fields. Coverage can be: colored; . Two-layer (thin colored top layer and thick black). In this case, the black layer is laid first, after it dries, the colored layer is laid (with a stacker or with a PTJ-120 spray gun). For the manufacture of the colored layer, either black EPDM chips are used or only colored granules of EPDM synthetic rubber; . Black. The PTJ-120 Crumb and Glue Sprayer can be used as optional equipment. When spraying on a seamless black layer, you can get 2 types of surface - permeable and waterproof, depending on the ratio of crumbs and glue, crumb fraction. When laying the top colored layer with a paver, a permeable surface with a drainage effect is obtained, on which puddles do not form even in the rain. On any type of the surface described above, in the cold season, you can pour an ice rink, and in the warm season it will again be a sports or playground. Any color options are possible: any uniform color, coating with splashes. On sports and playgrounds, it is possible to apply various markings and patterns. Products can be from 4 to 20 mm thick (specified during laying). general description technologies 1. Materials (crumb, binder), equipment (stacker, mixer) are brought to the place of laying. 2. The surface is being prepared. If it is a concrete screed, dirt and dust are removed. 3. Primed with a thin layer of adhesive, which is used for cold laying. Glue consumption from 100 to 300 g/m2 depending on the surface topography. This contributes to improved adhesion of the material. 4. Equipment and materials are placed in their places. 5. On the mixer, crumbs and a binder (glue) are mixed. To do this, the crumb and glue warehouse should be located next to the mixer. Scales are needed for accurate dosing of the binder. Depending on the crumb fraction, type of mixer, air humidity and brand of binder, the ratio of glue to crumb should be 15-20% of the crumb mass. After the completion of the mixing cycle of the components, the resulting mixture is moved to the trolley and transported to the place of laying and poured onto the work surface of the stacker. For mixing and transportation, 1-3 people are needed, depending on the required productivity. 6. The scattered mass is leveled by the stacker, the joints with the previously laid layer of material are leveled manually by the stacker operator using special trowels. All possible surface irregularities are filled and leveled with the material. 7. Drying time 8-24 hours (depending on temperature, humidity, binder brand). After that, you can lay or spray the top color coat. The second layer is laid without prior primer. 8. If necessary, markup or drawing is applied. The glue is mixed with the required color of the dye, and the resulting mixture is applied with a brush to the pre-lined markings. Another option is possible: the necessary pattern, logo, inscription is cut out from the rolled rubber material according to the template and placed on the glue on the first black layer. Then covered, glued protective coating and a second color coat is applied on top. After drying, the protective material is removed, and we get a coating with a pattern, inscription or logo. - The surface to be applied must be dry and clean. - It is not allowed to work at negative air temperatures and precipitation. -The crumb used must be dry. The size of crumb fractions is from 1 to 4 mm. - Weight of 1 m2 of coating, 10 mm thick: 7-8 kg. - Service life of a covering not less than 10 years.

The latest technological advances have given us seamless rubber flooring.

Eco-friendly, injury-preventing material has found its application in the field of physical education and sports, outdoor activities.

The manufacture of a rubber coating can be carried out both using improvised means, and by partial mechanization of the process.

Consider the technology of laying a seamless rubber coating in more detail.

Regardless of the chosen rubber coating manufacturing technology, you will need:

• rubber crumb;
• adhesive composition;
• coloring pigments.

Rubber crumb

The degree of crushing of rubber tires determines the further scope of their use.

• chit smaller than 2 mm– formation of two-layer floor coverings for sports grounds and stadiums, running tracks, swimming pools, industrial workshops, car washes, livestock buildings;
• granules size 2-5 mm- filling of sports equipment, arrangement of the base for children's, sports and playgrounds.

When purchasing rubber crumb, pay attention to the following conditions:

• product cleaning quality;
• sorting by size;
• crumb shape.

For 1 m 2 of coverage, an average of 8 kg of rubber will be required.

The crumb produced by mechanical processing of tires has even edges, so much less binding elements are required than when using a grated counterpart.

The cost of finished rubber crumb starts from 10-12 rubles. per 1 kg of product and depends on the volume of purchase and seasonal demand for products.

Adhesive composition

For making seamless floor covering rubber used predominantly one-component formulations, less often - two-component.

Single component

Bitumen or polyurethane is used as a binder in the adhesive mixture. The choice of glue is determined by the operational properties of the future coating and the working conditions.

Adhesive for rubber coatings based on polyurethane has the following properties:

1. Water permeability. Water does not linger on the surface of the coating made with polyurethane, but passes through it. The finished coating can be used both indoors with a high level of humidity, and on outdoors.
2. High abrasion resistance. Suitable for the manufacture of floors experiencing high mechanical loads.
3. Elasticity. Allows you to form a safety coating for sports.
4. Environmental friendliness. The absence of harmful fumes makes it possible to use rubber floors in rooms for the games of very young children.
5. Long service life due to resistance to ultraviolet and sudden changes in temperature.

Another feature of the polyurethane binder is that it hardens at a sufficient high level humidity - 60-70% and temperature environment 20-25 o.

Compounds with bitumen are less suitable for making a seamless rubber surface.

Bitumen components do not mix well with paint and have lower performance properties.

The cost of 1 kg. one-component glue - from 185 rubles.

Two-component

A two-component adhesive is sold in separate containers, in which an epoxy-polyurethane binder and a chemical hardener are placed.

Mixing both components directly at the time of work.

When choosing a two-component adhesive for rubber crumb, it should be noted that the finished composition should be used in the first 30-40 minutes after its preparation.

This feature of the adhesive requires a careful calculation of the need for it for the production of work in this period of time. The advantage of a two-component composition is high chemical inertness.

The cost of 1 kg of glue - from 165 rubles.

Job requirements

The formation of a high-quality seamless rubber coating is possible only with strict adherence to the proportions recommended by the adhesive manufacturer.

Approximately 250 g of polyurethane adhesive is required per 1 kg of crumb rubber, the consumption of the binder depends on the size of the granules used.

Another condition for uniform polymerization of the working composition is maintaining required level humidity and temperature at the place of work.

Pigment formulations

Coloring of the future rubber coating is given by coloring pigments added to the working composition.

What should you pay attention to when choosing a paint?

• production from inorganic components;
• the presence of iron oxides.

Such a component composition of the dye makes it rain and UV resistant extending the aesthetic life of the coating.

The dosage of the dye depends on the desired color intensity of the formed surface and averages 62 g per 1 kg of crumb rubber.

The homogeneous consistency of the working composition is achieved by strict adherence to the manufacturer's recipe.

The cost of 1 kg of dye - from 110 rubles.

Priming material

A polyurethane-based primer is another component, without which it is impossible quality styling rubber seamless coating.

The material with good penetrating ability ensures high adhesion of the components of the mixture to be laid with the coating to be treated.

The price of a primer ranges from 10 rubles. for 1 kg. and depends on the purchased volumes.

Coating Equipment

The quality and durability of the future product largely depend on the equipment used in the production.

The use of special mechanisms is especially important if it is necessary to manufacture a two-layer coating or production of large volume works.

Equipment not required to be purchased can be rented the accessories you need.

Mixer

High-quality mixing of rubber crumb, glue and dye is ensured by using an industrial mixer.

Undissolved lumps in the composition of the working mixture are a manufacturing defect and can nullify all your attempts to create a high-quality seamless rubber coating.

Distinctive features of the mixing device - simple design and operational reliability.

Consider some types of crumb rubber mixers:

• device with top feed raw materials and side unloading window;
• designs with removable tanks and top position of the engine;
• screw mixer.

Good feedback from the Internet community has a mixer for crumb rubber MSRK-90. The device has a top loading of the components of the working composition and a convenient window for removing the finished mixture.

The capacity of the mixer and the power of its engine allow mix the mixture well from 90 kg of rubber.

auto stacker

Mechanized laying of rubber coating has the following dignity:

• high labor productivity, which allows, depending on the brand of equipment used, to lay a surface of up to 1000 m 2;
• downsizing for the production of works;
• possibility of customization equipment for obtaining coverage of strictly specified parameters;
• convenience and basic service.

The paver is a piece of equipment equipped with an adjustable scraper on the front of the working platform, a pressure plate and heating elements on the back of the device.

The stacker is controlled by adjusting the speed and direction of its movement; there are also devices for manually moving the mechanism.

In the process of work, the rubber mixture spread on the rough surface is distributed and leveled by the stacker over the entire width working area devices. Heating elements heat the rubber mixture, thereby accelerating the process of polymerization of the adhesive.

Roller

Hand rollers for compacting the rubber-adhesive mixture should be quite heavy. Light fixtures not able to effectively compact the working composition, which will lead to the rapid destruction of the rubber coating.

There are three types of rollers used to form rubber mats:

• large roller for compaction of the main area of ​​coverage;
• roller for rolling joints and joints;
• roller for forming the corners of the surface.

Composition sprayer

Spray device provides technology uniform application working composition on the treated surface.

The advantage of the sprayer is the ability to hide minor "flaws" in the production of coatings by applying a thin finishing layer of raw materials.

The operation of the equipment is carried out as follows - the composition ready for application to the working plane is placed in the receiving hopper.

Using a pump, mix under high pressure is fed to the spray gun and applied to the surface with a layer of the required thickness, raw material spraying radius is adjustable.

The equipment works well with crumbs up to 1 mm in size. A larger fraction clogs the spray nozzle and disables it.

Weighing equipment

Accurate observance of the proportions of the ingredients of the working composition is a condition for obtaining a high-quality seamless rubber surface.

Measuring containers are not allowed. to determine the volume of one or another component of the mixture - a deviation from the norm of 5-10% significantly reduces performance characteristics finished cover.

Rubber coating technologies

Laying a seamless rubber coating is available even to amateur craftsmen. The main requirement for the production of works - strict adherence to instructions in the preparation of the working composition, as well as careful mixing and application of the mixture.

Single layer surfaces

Installation of the rubber coating is carried out in the following sequence.

Foundation preparation

The service life of the future coating largely depends on the quality and type of base.

The following types of bases are most popular:

crushed stone. It is used for the installation of rubber coating on playgrounds, sports facilities designed for running and walking.

Profitability and moisture permeability are the main features of the crushed stone base.

The coating laid on crushed stone must have a thickness of more than 15 mm. and used exclusively for light loads.

Excavation is in progress at the work site.

The size of the recess depends on the level of occurrence ground water, as well as the type of soil and its drainage capacity.

The distance from stormwater wells also matters.

The next step is soil compaction and drainage. Then layers of sand and crushed stone of various fractions are laid with mandatory compaction. Upper layer formed from fine grain.

A high-quality crushed stone base has a slight slope for moisture removal, does not contain depressions and bulges, and does not squeeze when walking.

Asphalt. The base of the asphalt mix allows laying crumb rubber in a layer of 1 cm. This type of base is used in the construction of professional sports facilities. Its advantage is high strength, which can withstand the weight of special equipment.

Another condition is the absence of stains from oil products.

The asphalt base can be formed in one or two layers, with the obligatory arrangement of underlying layers of sand and gravel.

Compliance with the manufacturing technology of asphalt pavement makes it possible to obtain a base that can withstand significant mechanical loads.

Concrete. The concrete base is the strongest and most durable, has a universal scope of use.

Like asphalt pavement withstands heavy loads and can even be used to form the floor in car parks.

quality concrete pavement requires an effective waterproofing and polishing device.

What else to pay attention to when installing a concrete base?

1. The thickness of the concrete layer must be more than 1.2 cm, the exact amount of concrete per 1 m 2 of the working area is calculated based on the type of soil and the planned loads on the base.
2. Concrete reinforcement should not be neglected. Fine-mesh wire mesh significantly improves the quality of the future base.
3. The formation of the base plane under a slope and careful waterproofing prevents the delamination of the concrete layer and the accumulation of puddles on its surface.
4. It is obligatory to grind concrete by sandblasting to achieve full adhesion with a layer of rubber and glue.
5. The base is considered ready when its moisture content is less than 4%.

rubber layer on concrete base- from 1 cm.

Primer

To improve the "adhesive" properties of the adhesive with the subfloor or base, it is necessary to prime the surface.

For these purposes, you can use store-bought priming mixtures or prepare them yourself.

For the simplest primer, you will need turpentine and a polyurethane-based adhesive. The components are mixed in equal proportions and applied to the treated surface with a roller.

The term of "solidification" of the primer depends on the level of humidity, the temperature of the place of work and is from half an hour to several hours. The consumption of the mixture per 1 m 2 of the surface is 300 g.

Calculation of components and kneading of the working mixture

Depending on the volume of the mixer tank and the power of its engine, it is possible to immediately prepare the composition for laying on 5-10 m 2 of the base.

So, with the gradual formation of a rubber coating 1 cm thick in “steps” of 5 m 2, you will need:

1. Rubber crumb - 40 kg.
2. Glue - 8.5 kg (see the instructions for use for exact proportions).
3. Dye - 2.5 kg.

The finished components are fed into the mixer tank in the following order: crumb, after 2 minutes pigment dye. After uniform coloring of the rubber particles, glue is added to the mixer. Mixing of the composition is carried out until a homogeneous mixture is obtained and, as a rule, takes 10-15 minutes.

Application

For the convenience of work, you can mark the work surface into segments with an area of ​​​​1 m 2. A mixture weighing 10.2 kg is poured into each square. The rubber-adhesive mass is leveled over the surface with special tools in the form of spatulas and pressed down with rollers.

With the mechanized method of work, the inventory at hand is replaced by an auto stacker.

Only minor flaws in the finished surface are manually corrected, which periodically occur when using equipment over large areas.

Complete sintering of the composition depends on weather conditions and averages 8-12 hours.

Dual layer technology

Laying rubber coating can be done in one or two layers. With a two-layer technology of work, you can save on painting the lower layers of rubber.

To make the coating more elastic, it is advisable to use a crumb of a fine fraction (up to 2.5 m) to form the first rubber layer.

After the first layer of rubber has completely cured, it is necessary to reinforce the surface with a fiberglass mesh. This technique increases the strength of the coating, increases its service life.

The top layer of the rubber coating can be formed with the addition of ready-made dyed rubber granules or consist entirely of them. In this case, pigment dyes are not used.

The thickness of the top layer, depending on the purpose of using the future coating, is from 1 cm.

"Dry" floors

The technologies we have considered belong to the category of do-it-yourself installation of rubber floors using binders. There is another way, the so-called "dry" production of a rubber floor.

Laying technology is a simple spreading of crumb rubber with a layer of more than 8 cm on the base.

This way of doing work good for quick shaping temporary flooring, and this is where all its advantages are limited.

Production cost

Do-it-yourself production and do-it-yourself laying of a rubber coating is the most a budget option production of works. The cost of third-party services varies greatly and depends on the following factors:

• purpose of the product;
• coating thickness;
• number of product layers.

Let's present the results of a study of the market for services for the manufacture of seamless rubber surfaces (consumption and prices per 1 m 2) in the following table:

It is very cost-effective to set up a laying business if you are out of tires yourself. Of course, to open such a business, you need equipment, which you can get acquainted with.

In our country, rubber crumb coating has recently become very popular. produced in sports facilities, playgrounds, both outdoors and indoors. This is primarily due to the shock-absorbing properties. Plus, the safety of rubber coatings, high anti-slip properties, elasticity, resistance to abrasive wear. And the most important advantage of such a coating is its seamlessness.

The final result, that is, the durability and quality of the coating, will depend on such a simple operation in the future. If for some reason the granules are poorly covered with glue, and there will be no connection between the rubber crumb and the glue, this often leads to the appearance of holes, brittleness, cracks and bald spots in the coating. By the way, the life of a poorly mixed coating is not at all long - a maximum of 2 years. And if all the recommendations are followed, then the coating will last more than 10 years. The quality of the coating is greatly influenced by the quality of the components that make up the composition.

If in crumb rubber a large number of steel cord and textile, this may affect appearance and the coating in this case will become very dangerous for operation. Also, the presence of dust will impair the adhesion of the granules to the adhesive and often causes the destruction of the coating. If the quality of the adhesive is very low and does not provide the required viscosity of the mixture, then the laid coating will become brittle, brittle and lack shock-absorbing properties.

Methods for laying rubber crumb

It is best to entrust the laying of the coating to professionals, so as not to change it several times a year in the future. Although necessary components for such work have a low cost. As you know, today there are four methods for laying crumb rubber coatings:

• sprayer;
• manual way;
• combined method;
• method using an automated stacker.

It is better to entrust the laying of crumb rubber to professionals, then the coating will be of high quality and durable.

Types of equipment used

For laying a rubber coating, it is recommended to use special equipment. This makes it possible to reduce maintenance personnel and increase labor productivity. One of the specialized tools is the automated stacker. rubber tiles. It is a steel construction on tracks and consists of a pressure plate and a front scraper, which is manually adjustable, which allows you to set the required coating thickness. You can adjust the width using the upper limiter, and the plate has 4 functions.

The upper layer of rubber crumb is sprayed under high pressure

Rubber crumb is a seamless, elastic coating that is resistant to temperature extremes and precipitation. It is used for playgrounds, jogging and bicycle paths, space along pools and skating rinks.

PU glue

(In the picture: construction mixer)

• First mix the crumb rubber for 10 minutes
• Add glue to them - 20-25% by weight of crumb rubber. Stir the mixture for five minutes
• To work with crumb rubber outdoors, the air temperature must be +20 ºC and without precipitation

Equipment for laying crumb rubber

Depending on what area needs to be covered with crumb rubber, different equipment is used.

If we are talking about a large area, for example, a sports arena that is exposed, then an automatic rubber crumb stacker is indispensable. It allows you to control the thickness and width of the coating, work at high speed (at least 800 square meters per day), as well as evenly distribute the material over the surface, press it down so that it does not peel off.

(Illustrated: auto stacker)

Usage: pour the prepared polymer mixture onto the surface in even parts, then level it with an auto-layer.

The budgetary and easiest-to-use equipment for laying crumb rubber is a roller and a grater. A large roller and grater are used to compact the coating, a forming roller is used for corners and joints. Before starting, the tools are impregnated with turpentine so that the rubber crumb does not stick to the surface.

(In the picture: roller)

(In the picture: grater)

Usage: pour the prepared polymer mixture onto the surface in even parts, then level it with a roller and press down with a grater.

The atomizer consists of air compressor and pumps. It is used for spraying the second layer of rubber crumb, for covering vertical surfaces with a crumb layer up to 1 millimeter. It allows you to evenly apply the components and hide the unevenness of the first layer.

(In the picture: atomizer)

Usage: the polyurethane mixture is poured into the receiving hopper, from there it is fed to the spray gun with the help of a pump and applied under pressure to the surface.

After laying the rubber crumb, you need to wait until it dries for 24 hours. Full hardening of the coating occurs after five days.

Clean the equipment with organic solvents: acetone or xylene.
