Asbestos-free gaskets are based on various working conditions, and asbestos-free sealing materials are (using aramid fibers, high-temperature-resistant synthetic mineral fibers, oil-resistant rubber and other materials), stamped and sheared by rolling method or various tools Various shapes of sealing products. Internationally recognized asbestos is a carcinogen. In the 1970s, many countries proposed asbestos-free solutions.
After more than 20 years of hard work, various series of non-asbestos gasket materials have been developed. In 1990, the US Environmental Protection Agency (EPA) issued government regulations to prohibit the use of asbestos materials and their products. Usually, advanced countries in the world have implemented asbestos-free materials in their respective application areas, comprehensively Asbestos materials are prohibited.
The history of domestic development The traditional asbestos materials have been continuously used in China for a long time. After my country's participation in the WTO, all walks of life in China are facing challenges from abroad, and the automobile industry is at the forefront of industrial transformation. As the giants of the automobile industry, Volkswagen and GM of the United States have brought the concept of asbestos-free sealing of automobiles to China. With the rapid development of industry and more foreign auto companies investing and building factories in China, asbestos-free auto parts have been started.
In the petrochemical and shipbuilding industries, the chemical corrosion of asbestos materials to steel is often a hidden danger of serious accidents; in the refrigeration industry, especially air conditioners and refrigerators, which are closely related to people's lives, asbestos will cause great harm to the human body and the environment. ASBESTOS FREE GASKET or NON ASBESTOS GASKET commonly referred to in European and American countries refers to 100% asbestos-free gaskets.
The sealing industry can be said to be a small industry, but the products can be used in conjunction with large industries. Whether aviation, navigation, petroleum, chemical industry, or machinery, power generation, metallurgy, mining, etc., are inseparable from seals. In short, wherever the center of organics, pumps, pipes, and valves rely on asbestos-free gaskets. Therefore, although the industry is small, the scope involved is very wide.
