Waste rubber is a kind of solid waste, and its main source is some rubber products, such as automobile tires, rubber hoses, tapes, rubber shoes and other products containing rubber. Due to the characteristics of rubber and plastic that are easy to age and break, 60% of the plastic will be converted into waste plastic after 1-2 years, and 40% of the rubber will become waste rubber. Waste plastics and waste rubber are buried in the soil without decomposing for a long time, which will affect the air permeability of the soil, hinder the flow of water and the development of crop roots, and pollute the environment. Therefore, for waste plastics, the recycling of rubber has become a topic of extensive discussion and concern in the whole society.

How to recycle rubber tires?

There are four main recycling methods for rubber tires, which are directly used, crushed or made into rubber powder, used as an asphalt modifier, and cracked and recycled.

1. Use directly. Direct use is to use the original shape or approximate prototype of waste rubber products. Tire retreading is the most effective, direct and economical direct utilization method. The most advanced tire retreading in the industry is the pre-vulcanized retreading method. The vulcanized tire tread glue is bonded to the polished carcass, and then the tire is put into the inflatable inner tube and the envelope, and then sent into a large vulcanization tank for vulcanization at a lower temperature and pressure, so that Multiple retreaded tires are produced at one time.

2. Crush or make rubber powder for later use

A very important way of recycling waste rubber is to make waste tires into rubber powder. Rubber powder is widely used in sports plastic sports fields, playgrounds, rubber floor tiles, waterproof membranes, waterproof coatings, road modified asphalt, rubber products and other fields. During recycling waste tire,it generally needs a rubber tire shredding machine to shred large tire into small part.

3. As an asphalt modifier:

Adding rubber powder to asphalt can improve the performance of asphalt and prolong the service life of asphalt pavement. Therefore, waste rubber and plastics can be used as asphalt modifiers.

4. Pyrolysis recovery

At present, the pyrolysis technology of waste rubber mainly focuses on thermal cracking, vacuum cracking and catalytic cracking under inert atmosphere. For example, gas, liquid and solid recovery products can be obtained by pyrolysis recovery process, and the gas obtained by pyrolysis can be used as fuel; liquid products can be purified twice through a certain separation technology to produce gasoline and other fuels; solid products are carbon materials , can be used to produce carbon black, and can also be used as carbon electrode material.

Waste tire recycling method

Disposal of waste tires includes cutting rings, extruding wires, cutting strips, cutting into pieces, beating rubber blocks, beating granules, grinding rubber powder, refining oil and so on.

Scrap tires can be cut into two halves by a cutting machine, and the split tires are convenient for long-distance transportation and subsequent shredding.

Using the ring cutting machine, the bezel of the tire can be cut off, and the steel wire of the bezel is separated through the wire extrusion machine and sold directly to generate income.

Cutting the tires into strips can increase the transport load through the strip cutter, and it can also facilitate the subsequent tires to be cut into blocks by a blocker.

The steel wires are separated, and the steel wire tires contain a large amount of steel wires. Through the steel wire separator, the steel wire inside can be separated. The separated steel wire can be reworked in a furnace, or the steel wire can be cut into pellets to make metal abrasives.

Tires are granulated, and the rubber granules made from waste tires can not only be used as fillers in sports venues such as football fields, basketball courts, and runways, but also can be used as rubber floor tiles and rubber coils.

Tire grinding, tire rubber powder can be used for reclaimed rubber, rubber asphalt additives.

Tire oil refining, through the waste tire oil refining production line, the rubber oil contained in the tire can be extracted.
