In the process of processing tires, rubber must pass through the process of rubber mixing, vulcanization, etc., under the effect of high temperature and high pressure, some toxic and harmful gases will be released. These gases hinder people's health. To improve the working environment of operators and reduce toxic and harmful gases, it is important to screen those toxic and harmful rubber auxiliaries and use environmentally friendly rubber auxiliaries.
During the use of the tire, it continues to be exposed to high temperature and high pressure, causing the tire to age and release some harmful gases. The United States has used this to set up barriers to the export of some tire companies in China. Japan Bridgestone Tire Co., Ltd. has developed a common additive, which makes the tire rubber harden due to the heat generation and the continuous crosslinking reaction of sulfur and rubber molecules, which improves the braking and traction of the tire. Sex and tire noise.
The noise of the tire is also an environmental pollution. Thousands of cars on a road will continue to drive, which will resonate, which will affect people's rest and sleep. The noise isolation zone is established at both ends of the urban elevated road, which is a way of depression. Fundamentally, it is still necessary to improve the structure of the tire and the formulation of the rubber.
