What materials are often used in the production of plate heat exchanger gaskets?
880 plate heat exchanger gasket is an important basic component of mechanical equipment, and its manufacturing accuracy requirements are relatively high. With the rapid growth of industrial products such as plate heat exchanger equipment in my country, the gasket is no matter in terms of structure. Still need superb technology and equipment support in terms of materials. Generally speaking, what materials are often used by plate heat exchanger manufacturers in the production of plate heat exchanger gaskets? The following will reveal the answer for us: New materials launched by domestic and foreign companies: 1. Fluoroplastics coated with rubber products such as fluorinated propylene and perfluorinated compounds, coated with rubber O-rings and rubber gaskets, improve the resistance of rubber products Media performance. 2. Perfluoroelastomer has the advantages of high temperature resistance (250℃～320℃), gas resistance and strong chemical corrosion, good elasticity, low compression set and good elasticity, and it can adapt to some very harsh working conditions. It is used in chemical, food, printing, semiconductor and other industries. 3. The unique polyurethane material has good lubricity, and the ultra-low temperature resistance can reach 20K (-253℃). It can be used in ultra-low temperature conditions. 4. Polytetrafluoroethylene composite and modification In order to overcome the shortcomings of cold flow and poor thermal conductivity, and reduce product wear, the material is used as the matrix to composite with carbon fiber, polyimide, polyether ether ketone, polyphenylene sulfide and other materials. Develop oil-free lubrication seals (piston rings, guide rings, packing rings), which are widely used in medium and high-pressure oil-free compressors. The seals developed by Guangyan Sealing are used in many well-known domestic compressors. The application of expanded polytetrafluoroethylene, expanded polytetrafluoroethylene is stretched and expanded to form a new material with strong, porous and highly fibrous material, which not only maintains the unique chemical stability of polytetrafluoroethylene itself , Very low coefficient of friction, wide operating temperature, and its microfibrillated internal structure makes its products more tough than imagined. In the new international environment, the manufacturing base of rubber and plastic seal products will continue to shift to my country. my country's rubber and plastic seals industry will also usher in a period of leaping development, and it will also make greater contributions to the development of my country's new industrialization. The above are some of the materials used in the production of plate heat exchanger gaskets.
