Product Name: 4150 Gasket
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.
Types of gaskets and their scope of application Types of gaskets and their scope of application Various types of machines (equipment), especially equipment such as pressure vessels, pipelines and valves, usually use gasket sealing structures. The simpler gasket is a flat gasket. The entire gasket is composed of the same material and is used as a static seal for the common joint surfaces of mechanical equipment (such as gearbox seals).
Application medium: various gases, water, steam, chemical solvents and various oils, etc.
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.
The ideal gasket structure should be plastic on the surface, while the inner layer is elastomer. The plastic outer layer can ensure the seal and close contact with each other, and even fit, while the inner layer can compensate for the slight separation of the sealing surface and always adhere to the sealing surface with a certain size. Many composite gaskets are based on this idea or slightly modified, but the principle is the same.
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.
High smoothness-small friction coefficient (0.04) in plastics; non-stick-has a small surface tension in solid materials, does not adhere to any substance; non-toxic, physiologically inert; excellent electrical properties, ideal C level Insulation Materials. PTFE materials are widely used in important fields, such as defense and military industries, nuclear energy, petroleum, radio, electrical machinery and chemical industries.
