product description:

Non-asbestos gasket PN1500 is a non-asbestos material with excellent performance based on the introduction of foreign advanced production technology. It is specially made of aramid fiber, high temperature resistant synthetic mineral fiber, oil resistant rubber and other materials by roller pressing method. It has the properties of temperature resistance, pressure resistance, oil resistance, excellent air tightness, and compression resilience. It is completely OK after testing. Substitute an imported non-asbestos material. It is a 100% asbestos-free high-quality environmental protection material, which has been exported to many countries and regions in Europe, America and other countries.

Application medium: various gases, water, steam, chemical solvents and various oils, etc.

Traditional asbestos materials have been used in China for a long time. After China joined the WTO, all Chinese industries are facing challenges from abroad. The automobile industry is at the forefront of industrial reforms. Volkswagen and General Motors in the United States, as giants in the automotive industry, introduced the concept of asbestos-free automotive seals to China. With the rapid development of the industry and more and more foreign auto companies investing and building factories in China, the non-asbestosization of auto parts has begun. In the petrochemical and shipbuilding industries, the chemical corrosion of asbestos to steel is usually a hidden danger for major accidents; in the refrigeration industry, especially air conditioners and refrigerators are closely related to people's lives. Asbestos can cause great harm to human body and the environment.

Classification of non-asbestos gaskets:

1. According to the production process of the material, the non-asbestos gasket can be divided into two types: the roll pressing process, namely the roll pressing board produced by the CAF (compressed asbestos rubber sheet) method and the copy board produced by the copy method (paper making method), both of which are It is a new type of environmentally friendly sealing product. Roller plate is generally used for pipe flange sealing, ZD-G1500 is a kind of roller plate. The copy board is mainly used for sealing parts of motor vehicles, such as engine gaskets, internal combustion engine cylinder gaskets, exhaust pipe gaskets, etc.

2. According to the physical performance level, it can be divided into three different levels: low pressure, medium pressure and high pressure, as well as special non-asbestos gaskets such as oil resistance, acid resistance, pressure resistance, high temperature resistance, refrigeration industry refrigerant plates, airtight plates, and marine sealing plates. On the basis of the above materials, it can be reinforced by metal wire, coated with graphite to increase temperature resistance, graphite-containing non-asbestos graphite board, etc. Other performance non-asbestos boards and various gaskets can also be customized according to the special needs of customers.

The non-asbestos gaskets or non-asbestos gaskets usually mentioned in European and American countries refer to 100% asbestos-free gaskets. It should be said that translated into Chinese can be said to be "non-asbestos gasket" or "non-asbestos gasket", but in the Chinese market, some companies claim that this gasket contains a certain amount of asbestos (5-20%) as a non-asbestos gasket sheet. 100% asbestos-free gaskets are called non-asbestos gaskets.

Industry equipment: Products are widely used in power generation, metallurgy, shipbuilding, petrochemical and other industrial applications such as water, gas, oil and other media sealed pipeline flanges, valves, heat exchangers, pressure vessels, mechanical equipment and engines, compressors, internal combustion engines , Machinery, instrumentation, heating and other industrial equipment.
