In the tire rubber powder application, the production of tire reclaimed rubber is the most important application. Understand the process of tire rubber tire reclaimed rubber production process Customers choose high-quality tire reclaimed rubber has great help today Xiaobian talk to you about the main process tire rubber tire reclaimed rubber production and the corresponding significance.
1, crushing: The process is to use the special equipment after the crushing of the tire particles to remove fibers and steel wire, in the crusher crushing; the purpose is to remove the tire particles in the fiber and steel impurities, generally after crushing tire rubber Powder diameter less than 1mm, that is about 20 mesh.
2, Sieving: In this procedure, 30 mesh or so of tire rubber powder is sieved through a sieve, and part of the fiber impurities are separated again.
3, sorting: The procedure according to the powder parts, powder diameter classification for the production of different specifications of tire reclaimed rubber to prepare, such as the fineness of the 80 tire tire powder production of ultra-fine reclaimed rubber, 40 mesh tires Top powder can produce high strength tread reclaimed rubber and so on.
4, add rubber chemicals: mainly the amount of activator and softener usage on the quality of tire reclaimed rubber great influence. The activator can accelerate the desulfurization process in the desulfurization process of the reclaimed rubber powder to shorten the desulfurization time and improve the technological performance of the reclaimed rubber. The working raw material of the activator is a combination of free radicals generated at high temperature and the rubber molecules to prevent the rubber molecules from being broken Chain after the re-polymerization; softener's main role is to infiltrate, the rubber molecules by thermal expansion of the rubber molecules make the chain between the force, which will help break the chain, increasing the distance between molecules and reduce desulfurization has been reduced again the structure of rubber molecules Possible.
5. Desulphurization: Desulphurization is the most important process in the process of tire rubber reclaimed from tire rubber powder. Through the chemical and physical processing and treatment such as heating, oxidation and regenerant, the cross-linking bonds of CSC in vulcanized rubber rupture and destroy Molecular structure of the network, so that it occurs degradation, resulting in vulcanized rubber from the elastic state in a plastic state, the dynamic desulfurization oil method, water and oil method, screw extrusion, microwave desulfurization method.
6, kneading: After desulfurization rubber plasticity is low, the need for repeated kneading, including thin continuous continuous kneading method and stand-alone automatic turning material kneading.
7, filter plastic: The purpose of plastic filter is to remove the tire rubber powder in the metal, fiber and other impurities to improve the purity of tire reclaimed rubber.
8, in a piece of refining: The purpose of this process is the use of shear force to make the rubber molecules further fracture, the second is at a small roll distance can be crushed rubber not fully desulfurized hard particles, or the particles Discharged to both ends of the roller to clear; refiners can be cut in pieces on the rubber, rubber tires to get the finished product.
Hebei Hongyun recycled rubber factory production of tire reclaimed rubber tire used their own production of rubber powder as raw material, long-term stable product quality, adequate supply, rubber products companies can be assured choice.
