The temperature is room temperature. Spray KNM22 polymer or do lined anti-corrosion layer, valve pipe fittings also use PTFE. Because the corrosion principle is vacuole stress corrosion, the bubble group has a comprehensive effect on the physical damage and chemical corrosion of the stainless steel grain boundary, surface passivation layer. You can spray PTFE, but the spraying should be heat treatment, there are requirements for the volume of the treatment furnace, you can consider using KNM22 polymer or pp plate as a liner. KNM22 polymer ceramic polymer is suitable for reaction tanks, condensation equipment, production ceramic welding tape pipelines and metallurgy, mining, sewage treatment equipment, light industry and other enterprise equipment of normal temperature and high temperature heavy corrosion protection in petroleum, chemical and fertilizer industries. Suitable for metal, concrete, stone, ceramics, glass and other matrix materials.

High temperature resistance characteristics of ceramics:

Ceramic materials play a decisive role in high-temperature applications over a continuous operating temperature range of 180 °C to more than 1200 °C. Due to these extreme temperatures, it is not possible to use plastic materials. Many materials exist Kamado bbq grill in the form of molten substances or even steam, and when the temperature rises, the metal loses its strength. This is the clear difference between ceramic materials and metallic materials. For example, the bending strength of silicon nitride and zirconia can be compared to steel and remain virtually unchanged at temperatures up to 1000 °C. However, depending on the alloy, the bending strength of the steel has decreased at temperatures of 300 °C and above. One of the oldest areas of application for ceramics is high-temperature measurement technology for thermocouple protection tubes with temperatures exceeding 1900 °C. Good high temperature performance is based on the high melting point of pure oxides: 2050°C for alumina and 2600°C for zirconia.

These characteristics can only be found in components if high-purity, high-quality substrates are used. Electrical insulation properties, wear resistance and stability remain unchanged up to 1800°C, especially for alumina. Stability can be improved by Ceramic Band Heater  higher porosity. However, if there are higher requirements for resistance to thermal shocks, silicon nitride or porous alumina materials with good resistance should be considered. Basically, large, thick-walled parts are more sensitive to temperature changes than small, thin-walled molded bodies.
