In addition to tire oil, that is, fuel oil, the products of waste tire refining include steel wire, carbon black, and combustible gas. The black face of the tire is due to the addition of carbon black to the rubber. Carbon black has excellent reinforcement to rubber and can give tires excellent wear resistance. By processing carbon black through a pulverizer, the by-products of waste tires can be turned into treasures. So, what is the use of carbon black from tire refining? The following is an analysis and introduction of the carbon black grinding mill manufacturer HCMilling(Guilin Hongcheng).

The waste tires undergo a cracking reaction through the oil refining equipment, and the rubber components are converted into oil and gas and exported from the cracking furnace. After the cracking is completed, the carbon black and the steel wire in the tire are left in the cracking furnace.

 

The output ratio of waste tire cracking is: tire oil 40%, carbon black 30%, steel wire 15%, in addition to these main components, there are some others. That is to say, one ton of waste tires can produce about 0.3 tons of carbon black.

 

The crude carbon black after thermal cracking of tires is a black powdery solid substance, which needs to be transported and stored in a closed environment. Carbon black itself can be reused, but if it is not properly treated, it will easily cause secondary pollution and waste of resources.

 

Carbon black is also very useful, but the carbon black used in tire oil refining is coarse carbon black, which is generally used in the following situations. Replaces general purpose carbon black as reinforcement. If you want to increase its added value, it can be further processed through a carbon black grinder.

 

The coarse carbon black produced in the cracking production process has a size of about 50-60 mesh, and a carbon black pulverizer is used to grind the cracked coarse carbon black to at least 325 mesh to achieve N-grade carbon black quality. It is close to N330, which is widely used in the market, and can be used as a reinforcing agent, filler or colorant in the basic rubber and plastics industry. Can be used to produce: rubber seals, rubber V-belts, plastic products, and pigments, etc.

Products and uses:

N550 is suitable for natural rubber and various synthetic rubbers. It is easy to disperse, and can impart high stiffness to the rubber compound. The extrusion speed is fast, the mouth expansion is small, and the extrusion surface is smooth. Vulcanized rubber has good high temperature performance and thermal conductivity, as well as better reinforcement performance, elasticity and recovery. Mainly used in tire cord rubber, sidewall, inner tube and extruded and calendered products.

 

N660 This product is suitable for all kinds of rubber. Compared with semi-reinforced carbon black, it has higher structure, finer particles, and is easy to disperse in the rubber compound. The tensile strength, tear strength and tensile stress of vulcanizate are relatively high High, but small deformation, low heat generation, good elasticity and buckling resistance. Mainly used for tire curtain tapes, inner tubes, bicycles, hoses, tapes, cables, footwear and calendered products, model products, etc.

 

N774 This product is suitable for all kinds of rubber. This product has wear resistance, tear resistance, heat resistance, cold resistance and oil resistance. It is a semi-reinforced carbon black with low pollution and low elongation. Its characteristics are that it can be filled in a large amount and the rubber compound has good processing performance. This carbon black imparts high elongation, low heat build-up, high elasticity and good aging resistance to the rubber compound, increases the processing fluidity of the rubber compound, improves the bonding effect between the product and other materials, and improves the appearance quality of the product. Belts or plies for tires, inner tubes, bicycle tires, hoses, tapes, cables, footwear and calendered products, model products, natural rubber, neoprene, nitrile rubber products, both reinforcing and filling.
