People’s desired tires for bicycles and mopeds that do not need to be inflated and are environmentally friendly are now on the market. In order to protect intellectual property rights and ensure product quality, Shanghai inventor Gong Ruihua and general manager of Shanghai High Polymer Rubber Company have applied for invention patents and utility model patents with the China Intellectual Property Office.
The name of this kind of tire is high-polymer microporous tire. The first successful trial production was on June 29, 1998. The method used was high-polymer injection molding process. This tire is a microporous inner structure tire. The high-polymer bicycle tires currently on the market do not need to be inflated, because the high-polymer bicycle tires have changed the defects of previous bicycle tires that leaked air and blew out after being punctured, and required valve cores and inflation tools to be constantly repaired. An international Internet search shows that high-polymer tires are the first tires in the world to be made by injection.
High-polymer microporous tires use rubber as the main raw material. They are modified or polymer-modified with other polymers and then injection molded. This changes the vulcanization molding process of traditional tires and pioneers A new process and new direction for tire development. This is a significant change in the century-old history of tire development. For more than a hundred years, tires have gone through the process of transformation from solid to pneumatic tires, and now there are microporous tires in between. The main material of tires, rubber, has also changed from unvulcanized to vulcanized, and now to dynamic tires. The process of vulcanization and self-crosslinking development. This is a progressive upgrading process, a development trend guided by high and new technologies.
