Application of PTFE Pall ring
PTFE Pall ring is used in various fluorine chemical industry, which normally it is used in electronic grade hydrofluoric acid projects. When it is applied in the exchange tower effect, packed tower is widely used in petroleum, chemical, pharmaceutical, water treatment and environmental protection fields. In a tower column, there are usually two or more media for absorption and chemical reactions. The medium usually includes two types, liquid-liquid reaction and gas-liquid reaction, for example, in the environmental protection industry waste water and waste gas treatment is widely used in packed towers. Without the filler, the mixture exchange in the tower would not be sufficient. Therefore, the production of PTFE Pall ring, rassie ring and other fillers, so that the material in the tower full exchange, tower resistance can not be too high. The traditional Pall ring is a structural form of packed tower. There are many Windows on the ring wall, so that the gas and liquid in the packed tower can freely pass through these Windows. However, the traditional Pall ring has a single structure and cannot meet the needs of increasingly industrial environment treatment.
Can erode glass and silicate to form gaseous silicon tetrafluoride. Soluble in water, alcohol, hard to dissolve in other solvents. High purity hydrofluoric acid for strong acid cleaning, corrosive agent, can be used with nitric acid, glacial acetic acid, hydrogen peroxide and ammonium hydroxide configuration.
Polytetrafluoroethylene, commonly known as PFA resin, is a relatively new fluorine plastic that can be fused and processed. Pfos has a high melting point, with densities ranging from 2.13 g/cc to 2.16 g/cc. PFA has heat resistance, cold resistance, chemical stability, mechanical properties, crack resistance and crack resistance. At the same time, the para polyphenol compound PPL is also very ideal in metallurgy, chemical and other industries. High temperature resistant, para-polybenzene has better thermal stability, corrosion resistance and self-lubricating properties than molybdenum disulfide and graphite. The molecular chain of PPL is insoluble because it is very rigid and regular.
PTFE Pall ring packing is applied to electronic grade hydrofluoric acid Phase II project specification 50mm PTFE Pall ring, which is used in the cleaning and corrosion of integrated circuit (IC) and very large scale integrated circuit (VLSI) chips. It is one of the key basic chemical materials in the manufacturing process of microelectronics industry.
PTFE Pall ring has the advantages of simple structure, easy processing and manufacturing, long service life, reduced filler replacement times, promoted the normal continuous production of chemical industry, and reduced production costs. PTFE packing can be used in various occasions, a wide range of applications, can be used in chemical industry, metallurgy, oxygen and other industries of drying tower, absorption tower, washing tower and regeneration tower.
