High temperature gasket There are many kinds, whether it is metal or nonmetal, organic or inorganic. If you want to choose a good set of high temperature resistant gasket for the equipment, you need to make a procurement plan according to the equipment requirements. Only those with appropriate performance can be used in the equipment. Because there are many kinds of high-temperature gasket, today we take silicone gasket as the core product to introduce some of its properties.

 How many degrees of high temperature can the silicone products in the high temperature gasket bear?

First of all, silicone gasket is more practical in life; under normal circumstances, the high temperature that people can contact in life may be hundreds of degrees Celsius, which is easy to scald the skin. The silicone gasket has a good anti-skid performance, and compared with the metal gasket, its thermal conductivity is low, the external heat dissipation capacity is poor, can give the staff a good protection.

Secondly, when silicone gasket is used as high temperature resistant gasket, it can be classified as a series of high temperature resistant products. However, due to its own characteristics, the melting point of silicone gasket is relatively low compared with metal. Therefore, at present, the temperature that the silicone gasket on the market can withstand is between 150 and 200 ℃, and it is difficult to have more than 300 products. Of course, in order to meet the market demand, some products will be organically integrated with other non-metallic materials, so that the products not only contain the characteristics of silica gel, but also greatly improve the temperature it can withstand, so as to realize the double combination of performance and high temperature.

Considering the characteristics of high temperature gasket made of silica gel, at present, most of the places that can be used are pipe flanges for transporting hot water. Good elasticity can make up for the gap when sealing. The temperature range of 200 ℃ can fully meet the actual temperature requirements of hot water pipeline. In addition, it can also be used in some normal temperature liquid transportation pipelines. Of course, the actual characteristics of the liquid, such as corrosivity and oxidation, should also be considered. Although silica gel generally has good anti-corrosion properties, it is difficult to avoid oxidation corrosion for some strong acids and bases, so the specific requirements should be determined according to the specific situation.

If you want to choose a good set of high temperature resistant gasket for the equipment, more often, it is necessary to develop a procurement plan according to the equipment requirements, and only those with appropriate performance can be applied in the equipment. Because there are many kinds of high-temperature gasket, today we take silicone gasket as the core product to introduce some of its properties.
