Products mainly made of asbestos free sealing materials
Asbestos free gaskets are sealing products of various shapes that are made by stamping and shearing with various tools using asbestos free sealing materials (such as aramid fibers, high-temperature resistant synthetic mineral fibers, oil resistant rubber, etc.) according to various specific working conditions.
Chinese name: Asbestos free gasket is made of asbestos free sealing material (using aramid fiber) according to various specific working conditions
development history
International Development History
It is internationally recognized that asbestos is a carcinogen. In the 1970s, many countries proposed asbestos free plans. After more than 20 years of effort, countries such as the United States, Japan, and Australia have successively developed various series of asbestos free gasket materials. In 1990, the US Environmental Protection Agency EPA issued government regulations prohibiting the use of asbestos materials and their products. Nowadays, advanced countries in the world have promoted asbestos free materials to various application fields and completely prohibited asbestos materials.
Domestic Development History
Traditional asbestos materials have been used in China for a long time. After China's accession to the WTO, various industries in China are facing challenges from abroad, and the automotive industry is at the forefront of industrial reform. As automotive giants, Volkswagen Germany and General Motors of the United States have introduced the concept of asbestos free sealing for automobiles into China. With the rapid development of the domestic automotive industry and more foreign automobile enterprises investing and building factories in China, the asbestos free production of automotive components has started; In the petrochemical and shipbuilding industries, the chemical corrosion caused by asbestos materials to steel bodies is often a hidden danger of major accidents; In the refrigeration industry, especially air conditioning and refrigerators, which are closely related to people's lives, asbestos can cause great harm to both the human body and the environment.
The ASBESTOS FREE GASKET or NON ASBESTOS GASKET commonly referred to in European and American countries refers to gaskets that are 100% asbestos free. It should be said that it can be translated into Chinese as "non asbestos gasket" or "non asbestos gasket". However, in the Chinese market, some companies refer to gaskets containing a certain amount of asbestos (5-20%) as non asbestos gaskets, while 100% asbestos free gaskets are referred to as non asbestos gaskets.
Classification and purpose
classification
Asbestos free gaskets can be roughly divided into asbestos free rubber plate gaskets and asbestos free sheet gaskets based on their formula, process performance, and use. They are both made from organic fibers such as aramid, plant fibers, nitrile rubber, and minerals through rolling or sheet manufacturing processes, and are a series of asbestos free sealing gaskets.
purpose
Due to their high strength, good resilience, and excellent impermeability, the asbestos free gasket series is an excellent environmentally friendly sealing gasket for replacing asbestos gaskets in the automotive and industrial machinery fields.
