The price of crumb rubber for 1 kg and a ton: how much does secondary raw material from tires cost?

Tile selection criteria

The quality of the crumb directly affects the durability of the coating. Reliable materials made in accordance with GOST and in strict adherence to production technology can last at least 10 years

In order not to be mistaken in the choice, it is important to evaluate the material by conducting the following experiments:

• it is recommended to run your palm several times along the front and back of the material; if the optimal amount of binding components was used in the manufacture of the product, the crumb will not crumble;
• you should carefully examine several tiles from the batch to choose from; chipped sides or chipped surfaces will indicate poor quality products;
• the tiles must be even, deviation is allowed, but not exceeding 1 mm; to evaluate the geometry, several products should be folded back to back; you can use a tape measure, ruler or other measuring devices;
• it is recommended to bend the tile - a high-quality product will instantly recover, and no cracks, irregularities or other deformation will appear on its surface;
• quality tiles have an even surface and uniform color.

How is rubber granulate produced?

The production of rubber granulated crumb consists of two main stages. At the first stage, rubber waste is crushed. At the second stage, the resulting crumb is subjected to additional temperature or chemical treatment to give its surface the required physical and chemical properties.

Destruction of industrial rubber goods to obtain crumb rubber can be carried out in two main ways:

• Mechanical grinding;
• Shock wave grinding.

The processing of tires into crumb rubber by mechanical grinding is a long-established, reliable and well-proven method. As a result of such processing, a crumb is obtained, which includes rubber, which has retained its molecular properties. On the basis of such crumbs, new high-quality rubber products are obtained.

Shock-wave grinding methods are new and, at the same time, promising for obtaining technologies for efficient processing of large volumes of rubber products that have been used up.

Precautionary measures

The components of the working solution for laying a monolithic rubber coating do not contain toxic or other substances harmful to human health. However, if moisture gets into the polyurethane adhesive, a chemical reaction will occur and the active release of carbon dioxide will begin. Inhaling it, the worker will feel weakness, loss of strength and drowsiness. To prevent the risks of these consequences, when working in closed rooms, ensure good air ventilation.

You need to lay the coating in special suits. All employees must be provided with a set of personal protective equipment:

• shoe covers;
• gloves;
• glasses;
• respirators when using dry dyes.

If polyurethane glue comes into contact with exposed skin, rinse off immediately under warm running water using soap.

What raw materials are used to obtain granules from crumb rubber?

Currently, most of the rubber crumb is produced by processing rubber waste. Most often, crumb is obtained from waste:

• Pneumatic tires;
• Pneumatic chambers;
• Tires with fabric or metal cord.

The use of such raw materials in the production of crumb determines its environmental friendliness. The fact is that all these materials belong to the 4th hazard class in terms of their impact on the environment. The term of their decomposition in natural conditions is more than 100 years. At the same time, in the places of their natural decomposition, a high concentration of harmful substances is formed, polluting the soil and air. In the event of the destruction of this waste by incineration, a significant amount of toxic substances is emitted, which enter the atmosphere with flue gases. The storage of such waste requires special conditions due to the increased fire hazard of rubber products.

Recycling this waste into crumb rubber makes it possible to obtain a material suitable for reuse in the manufacture of new rubber products, insulating materials, road coatings.

Specifications

Rubber crumb is a granulate of various fractions and shapes. Regardless of the method of production, it retains all the technical characteristics of the original recyclable materials. Granulate and products made from it have the following properties:

• mechanical purity (the content of impurities does not exceed 2%, metals - no more than 0.03%);
• density - up to 350 g / dm³;
• humidity - 0.9-0.95%.

An important parameter of crumb rubber flooring is its thickness. The minimum value is 10 mm, the maximum value is 40 mm. In addition, the coating is made from grains of various sizes. Popular fractions are 2 and 3 mm.

Who needs crumb rubber

Recently, among the organizations that need crumb rubber, a new customer has appeared - these are road builders. The mixture of crumb rubber embedded in the road substrate with an equal amount of metal and textile cords with standard additives of minerals allows the road surface to be maintained much longer. This happens due to the improvement of physical and mechanical parameters, cracks appear less often, and the elasticity of the coating increases, and most importantly, given the climatic conditions of our country, the frost resistance coefficient increases by almost half. Of the users who need crumb rubber, municipal and sports organizations occupy a special place. They are the customers of modern safe, wear-resistant and practical coatings for backyard sports playgrounds. But besides coatings, there is another area where crumb rubber is needed - filling punching bags and punching bags, as well as mats. There are a lot of areas of use for crumb rubber, because it is an amazing and unique product obtained from recycled materials.

In the future, only part of the crumb obtained from the recycling of used tires can be returned back to the tires.

Therefore, it is necessary to identify other areas of possible use of crushed rubber, especially in connection with the predicted increase in the processing of used tires. Namely:

the use of crumb rubber as a bitumen modifier for road construction (in asphalt concrete mixture);

production of rubber-bitumen mastics, roofing materials, composite materials (rubber coatings);

production of plates for various purposes:

- for livestock buildings;
- for floors of industrial buildings, sports and children's playgrounds;
- for tram and railway crossings;

regenerate production;

use as a sorbent for collecting crude oil and liquid petroleum products from the surface of water and earth;

manufacture of rubber footwear and other rubber products, anti-corrosion pastes.

The rubber crumb is in demand by rubber goods factories, tire factories, road repair enterprises, petrochemical enterprises that use crumb as a substitute for valuable rubber, as well as as a sorbent. One of the most promising areas of using crumb rubber is the construction of highways. Its introduction into the composition of the road surface significantly reduces the cost of work and increases the service life of such a surface.

Since the demand for rubber crumb is constantly growing, we invite other manufacturers to cooperate on mutually beneficial terms.

Materials (edit)

Regardless of the type of laying technology and manufacturing of the working mixture, when creating the coating, you will need crumb rubber, adhesive composition and coloring pigments. For the arrangement of floors in swimming pools, on sports grounds and treadmills, granules up to 2 mm in size are used. For playgrounds and playgrounds - medium fraction crumbs 2-5 mm.

A one-component adhesive, polyurethane, is most often used as a binder. It provides the coating with water resistance, abrasion resistance, resilience and durability. Less commonly, two-component binders are used, including epoxy-polyurethane adhesive and a hardener. Such a composition is inconvenient to use, since it must be used within half an hour after preparation.

You also need to pay close attention to dyes. The pigment gives color to the future coating

The composition of high-quality dyes should include various components of inorganic origin and iron oxyls. For high-quality installation, a primer is required. The base is processed with it to ensure good penetration of the laid mass.

Tools and equipment

The equipment used in the work will affect the reliability and durability of the created coating. The following equipment will be required when laying the pavement.

scales

To obtain a high-quality mixture when preparing it, it is important to observe the accuracy of the dosage of all components. Deviation from the prescribed rate even by 5% can lead to a decrease in the properties of the finished coating

Roller

This is a heavyweight manual unit designed to compact the working composition on the base.It is best to refuse the use of lightweight equipment - it will not be able to effectively compact the mixture, because of which the coating may soon collapse. In work, a thermal roller can be used for rolling seams and joints, as well as small rollers for corners.

Mixer

Thanks to this equipment, high-quality mixing of all components of the working mixture is carried out. For mixing the components, auger equipment or a unit with a top loading and a side discharge opening is suitable.

Auto stacker

This is a device, the working bodies of which are an adjustable scraper and a weighty pressing plate. The rear part of the equipment is equipped with heating elements for heating the working mixture to a predetermined temperature.

Spray

This equipment allows you to evenly apply the composition to the surface by spraying the finely dispersed composition over the surface. It is intended for applying a topcoat and masking small "flaws" made during installation.

And you will also need buckets, basins or wheelbarrows to transport the solution to the working area. After preparing the toolkit, you can start laying.

Views

The material is produced in the form of a granular placer - in this case, it is sold in kilograms. The crumb is needle-shaped, cubic or free-form

The main parameter that you need to pay attention to is the size of the fraction. Grains can be small, medium or large

The scatter can be colored or black. Due to the use of expensive pigments, colored granules will cost about 1.5-2 times more.

The material is produced in the form of tiles with different sizes (material in the form of a square with sides of 50x50 cm is popular). Manufacturers also offer granulate belts. Their width ranges from 30 to 50 cm, and their length does not exceed 10 m.

Applications

Tire granules, tiles and roll material based on crumb rubber are widely used in modern life. They are used to make rugs for outdoor use, equip floors in swimming pools, and ennoble parks.

Sports coverings

Rubber crumb coatings are classified as high-quality sports flooring. They are widely used when finishing treadmills in open and closed areas, they equip playing fields. This coverage meets international requirements. It provides:

• training athletes in a comfortable and safe environment;
• reliable and stable adhesion of the shoe to the lining surface.

Finishing work

Crumb rubber is widely used for interior and exterior decoration in commercial premises, less often in residential apartments. For outdoor work, it is used to decorate the stairs of shops, offices, shopping centers, hospitals, beauty salons. Due to the rough surface of the material and the relief structure, the safety of passers-by is ensured. Even on wet tiles, the risk of slipping and injury is reduced to zero.

The crumb is used when arranging a seamless floor covering in children's entertainment complexes and sports clubs. The widespread use of the material in the arrangement of play areas for children is due to its high injury safety.

Landscape design

Paths in city parks and squares are ennobled with decorative tiles and rubber crumb paving stones. They can pave paths in gardens, create a beautiful and comfortable area on a personal plot, dacha or in a country house. To improve the sites, you can use not only traditional rubber tiles, but also modular products. Their main feature is stubs. When laid, they snap together, forming a reliable and durable connection.

In landscape design, borders and posts made of crumb rubber are also used.With their help, you can not only decorate beautifully, but also delimit public areas.

Other variations of use

Crumb rubber is one of the best materials for the production of 3D figures. They are used to ennoble children's play areas, parks and various playgrounds. Granules can be used to make:

• cartoon characters;
• mushrooms;
• flowers;
• insects;
• animals.

Decorative figurines can create a fabulous atmosphere for children and adults. Such constructions are absolutely safe for health. Fine-grained rubber granulate is used as a filler in the production of frameless furniture, for example, bean bags, punching bags. The crumb is also used for sprinkling the top roofing layer. Due to this treatment, it is possible to achieve high moisture-repellent and anti-corrosion properties.

We order different fractions of crumb rubber at an attractive price.

In the production of crumb from car tires, not only size is important, but also its quality. Therefore, when ordering a product, it is necessary to clarify what equipment the manufacturer uses, whether he adheres to the intricacies of the technology.

The ISTIMPEX company is ready to offer excellent rubber crumb. We vouch for its quality, as we do it on modern equipment. It completely purifies the product, making the granules of the desired fraction. Also, our company produces high-quality glue, which is used when creating floor coverings. You can give them color with the help of pigments, which are very resistant to ultraviolet light, which means they do not fade under the sun's rays. We buy a MAGNESS rubber covering, which can be installed indoors and outdoors. Professional installers will carry out a project of any complexity. This serves as an additional guarantee of quality: compliance with the manufacturability of the installation process allows you to give the material such characteristics as safety, reliability, durability, elasticity.

Production technology

Crumb rubber is manufactured in accordance with the prescribed regulations governed by GOST 8407-89. For its production, such elements are used as:

• used or rejected car tires;
• cameras for flooring;
• rubber products unsuitable for further use.

There are 2 ways to produce granules.

• Shock wave. This technology is resorted to in large factories, since it requires the use of expensive equipment. The method consists in cooling tires to extremely low temperatures in cryogenic chambers and their subsequent crushing using a shock wave.
• The mechanical method of tire recycling is simpler, more affordable and less expensive. In this case, the grinding of recyclable materials is carried out as follows:
  1. at normal ambient temperatures;
  2. at high temperatures;
  3. with cooling of rubber products;
  4. using the "ozone knife";
  5. by forcing raw materials through the matrix of pressing equipment.

Let's consider the most popular type of processing - mechanical grinding at normal temperature. This production technology includes several stages.

• Sorting of tires by standard sizes. This stage is necessary for the subsequent adjustment of the cutting unit for certain dimensions of recyclable materials.
• Cutting rubber into pieces. The raw material is crushed by hydraulic shears, guillotines or mechanical knives.
• Grinding the resulting pieces to chips of 2-10 cm². For these purposes, shredder installations are used.
• Final grinding of raw materials. To do this, manufacturers use rotary-type milling equipment equipped with knives with 4 edges, or other units that can withstand high mechanical loads.
• Separation of granules from by-products through the use of air and magnetic separators.
• Filtration of crumbs into fractions by passing the granulate through a vibrating sieve.The resulting material is packaged and sent for further processing.

Most often, rubber granulate is used for the production of floor coverings. For their manufacture, the crumb is mixed with polyurethane and pigments on specialized industrial mixers for uniform connection of all components. Further, the raw material is baked - it is laid out in molds and sent to special pressing equipment. At a temperature of +140 degrees, the vulcanization of raw materials occurs.

Stages of work

It is not difficult to make your own rubber coating on the site, but in this matter it is important to follow the step-by-step instructions. All work is divided into several stages.

Preparation of the base

The first stage is preparatory. It is necessary for high-quality preparation of the base for the subsequent application of the mixture. Crumb rubber adheres well to asphalt, wood or concrete. To improve the adhesion properties, the surface must be cleaned of dirt (oil stains and dirt from chemicals are unacceptable). First of all, the concrete area must be moistened, and then sanded with a grinder. To clean the base from dirt and dust, use a construction vacuum cleaner. An ideally prepared substrate should be clean and dry with a slight roughness on the surface.

Often, the installation of the coating is carried out on the soil or sand and crushed stone flooring. In this case, experts recommend using a rolled rubber backing. It will help to reduce the consumption of the composition and increase the damping qualities of the finished surface. To strengthen the subgrade, it is recommended to apply a layer of geotextile fabric to it. It will protect the base from erosion by groundwater.

To increase adhesion, the prepared sub-base must be primed. For these purposes, you can take a store composition or make it yourself. To prepare the primer, you will need to mix turpentine and polyurethane glue in a 1: 1 ratio. The resulting solution is applied with a roller to the site. The approximate consumption of the primer is 300 g per 1 m2.

Preparation of the mixture

To form a decorative coating with a thickness of 1 cm and an area of ​​5 m2, you will need to take 40 kg of rubber granulate, 8.5 kg of polyurethane-based glue and at least 2.5 kg of pigment. First of all, add crumb to the loading tank, turn on the equipment and mix for 2-3 minutes. During storage, the granulate often cakes, and if you neglect its mixing, lumps may remain.

After mixing the crumbs, load the dye and mix it with the crumbs for 3 minutes to evenly distribute. The glue composition is poured into the rotating equipment in a stream - it is impossible to stop the operation of the equipment while mixing. Otherwise, lumps may form. After applying the glue, all components are mixed for 15 minutes. The mass should be dense and homogeneous.

Applying and rolling the cover

It is recommended to lay the mortar in segments with an area of ​​1 m2. For each such square, you need to distribute 10.2 kg of solution. The working composition must be leveled with spatulas alternately on all segments, and then compacted with a roller. With a large amount of work, the handy tool must be replaced with automatic stackers.

Laying the rubber cover can also be done using a two-layer technology. In this case, it will be possible to save money on painting the working mixture located in the lower part. To achieve greater elasticity of the coating for preparing the mortar for laying the first layer, it is recommended to take granules up to 2.5 mm.

After laying and hardening, a fiberglass mesh is laid on the rough layer. In the future, a finishing color coating is formed on it. It will take from 8 to 12 hours to sinter the composition.
