In the latest national promulgation of recycled rubber standards (GB / T 13460-2016 recycled rubber national standards), tread reclaimed rubber is defined as: the use of waste tires from the tread rubber reclaimed rubber is the tread reclaimed rubber , Is the new national standard of renewable plastic varieties. In actual production, tire tread reclaimed rubber and other parts of the tire reclaimed rubber, not only the raw material used in different parts of the performance characteristics also have great advantages.
The so-called tread reclaimed rubber is also a tire top reclaimed rubber, which is processed through a plurality of processes using the outermost textured rubber powder in the waste tire as a raw material. Tire top part of the tire is the tire with the highest amount of plastic, the best wear-resistant parts, so the production of tread reclaimed rubber effective rubber hydrocarbon content and wear resistance are superior to other sidewall reclaimed rubber, Wait.
Tread reclaimed rubber in addition to other parts of the tire reclaimed rubber in performance compared to different, there are many different specifications of the product itself.
1, under the same fineness, different types of tire tread rubber tire tread produced by the different intensity of reclaimed rubber, usually 1,200 tires fetal top reclaimed rubber greater strength;
2, the same tire tread rubber powder to take different production processes in different equipment produced tread reclaimed rubber tensile strength, elongation at break and other indicators are different, that is, the regeneration of different rubber plant tread regeneration Different plastic indicators, the best choice for the regular tire tire tread manufacturer of plastic, to avoid unnecessary trouble.
3, the same type of tire tread powder is different in fineness, the tensile strength of the recycled rubber produced is different, usually the finer the rubber powder, the lower the tensile strength of the recycled rubber, because the thinner the glue The internal structure of the powder molecule is more severely damaged, and the tensile strength of the fine-grain tire tread reclaimed rubber can be improved by a reasonable formulation adjustment.
Different indicators of different properties of the tread reclaimed rubber, the price is also different, rubber products manufacturers can choose according to their own needs a suitable tread reclaimed rubber: If you use tread reclaimed rubber production of high-strength and high wear-resistant molded rubber products such as conveyor belt You can use high-strength tread reclaimed rubber; if you use tread reclaimed rubber to produce extruded rubber products or rubber products that require a high degree of surface smoothness, you may want to try a super fine reclaimed rubber for tires with a size of 80 mesh or more.
