One of the disposal methods of used tires is the processing in tire rubber powder, which is used in the production of various rubber products. With the continuous development of tire rubber powder production technology, the fineness of tire rubber powder is getting higher and higher, and the use range is getting wider and wider. 80 tires or more of tire rubber powder can usually be directly added to the tire casing to improve the tire casing processing performance. , reduce the production costs of tires.
1. Add tire rubber compound tire rubber mixing effect
About 10 parts of the tire rubber powder of 80 or more can be uniformly dispersed in the rubber material of the tire outer tire. Generally, the higher the fineness of the tire rubber powder is, the better the dispersion of tire rubber powder is, but when the amount of tire rubber powder is too large in the tire rubber, the refining process It will destroy the original structure of the tire rubber powder, forming a sheet-like structure between the particles, and it is difficult to evenly disperse; the high-fineness tire rubber particles will have no effect on the extrusion effect of the tire casing, and it can also reduce the adhesive to some extent. Material viscosity, improve the fluidity of tire tire rubber; different manufacturers, different equipment, different raw materials produced by the tire rubber powder in the performance there are some differences, rubber products manufacturers can demand according to the characteristics of the rubber powder and tire needs to adjust the amount of powder .
2, tire rubber powder to improve tire properties
There is a clear interface between tire rubber powder and tire rubber. Under the effect of external force, it will affect the uniformity of tire vulcanization and reduce the tensile strength of the tire. Therefore, it is necessary to put the tire rubber powder in the open mill with a small roll gap. Pressure refining, then blended in the tire tire mix to improve the tire rubber powder activity, and appropriate adjustment tire tire curing system, improve the tire tire physical and mechanical properties, significantly improve tire tire tear strength and wear resistance, extend Tire life; refined tire rubber powder can improve the dynamic stickiness, elasticity and flex cracking resistance of the tire casing.
3, tire tire tire powder dosage
The tire rubber powder has sufficient raw materials and low price. The use of tire rubber tires can not only improve the wear resistance of tire tires, but also reduce the cost of raw materials, but the excessive use of rubber powder will reduce the performance of tire tires, so rubber tire processing manufacturers need The dosage of tire rubber powder in the tire is controlled between 10-15 parts, and the vulcanization system is properly adjusted to improve the physical properties of the tire tire. In the tire casing, the performance of the tire top and sidewall needs to be different, and the blending amount of tire rubber powder is also different.
