Plastic PP stepped ring packing, polypropylene stepped ring DN25 stepped ring CPVC double-layer stepped ring packing

Description :

　　The side end of the plastic PP stepped ring packing of Dier Chemical Packing Co., Ltd. in Pingxiang City, Jiangxi Province has been added with a flange, which not only increases the mechanical strength of the packing ring, but also increases the directional probability of packing placement due to the destruction of the symmetry of the packing structure. Due to the influence of flanging, the contact between the packing rings during packing changes from linear contact to point contact. In this way, not only do the gaps between the packing particles increase, reducing the resistance of gas passing through the packing layer, but these contact points can also serve as gathering and dispersing points for the liquid flowing along the packing surface, thereby promoting the surface renewal of the liquid film and improving the mass transfer efficiency of the packing

　　The aspect ratio of the plastic PP stepped ring is only half of that of the Bauer ring, and a tapered flange is added at one end of the ring to reduce the resistance of gas passing through the bed And it increases the flux, and the strength of the packing is also high. Due to its structural characteristics, the packing layers are mostly in point contact with each other. This not only increases the porosity and reduces the pressure drop, but also forms a collection or dispersion point for the liquid to flow along the surface of the packing, promoting the renewal of the liquid film surface and the mixing of the liquid, making the gas-liquid distribution uniform, increasing the gas-liquid contact surface and improving the mass transfer efficiency. It is generally made of plastics, ceramics, and metals. Different materials result in different structures. The internal reinforcement structure of the metal stepped ring is the same as that of the ball ring, and the tongue is bent into a leaf like shape; The internal reinforcement structure of plastic and ceramic step rings is similar to that of plastic ball rings.

　　PP (polypropylene): hardness and resistance to bending>PE (polyethylene), but the hardness also decreases when the temperature decreases. It is used at a higher temperature than PE and is resistant to alkali, acid, salt solvents, and many solvents such as alcohol, ketones, and esters. It has a temperature resistance of approximately 90 ℃ and can be used at room temperature of around 70 ℃. It has a density of 0.9-0.92g/cm3 and a white color;

　　RPP (Reinforced Polypropylene): It is a mixture of polypropylene with glass fibers or organic fibers, asbestos, or inorganic fillers (talcum powder, calcium carbonate). Generally, industrial glass fiber reinforced polypropylene contains 10-15% fibers. Due to the presence of glass fibers, it has good heat resistance and dimensional stability. The color can be produced in white and beige, with a temperature resistance of ≈ 120 ℃ and acid resistance.

　　PVC (polyvinyl chloride): a hard and non flexible thermal engineering plastic with moderate use temperature, alkali, acid, salt solvents, oil, fat, diesel, temperature resistance of ≈ 60 ℃, 1.38g/cm3, transparent white color.

　　CPVC (Chlorinated Polyvinyl Chloride): Resistant to corrosion from acids, alkalis, salts, oxidants, etc., with a density of 1.55g/cm3 and a gray color. It is commonly used in fluorine alkali industry projects and is highly resistant to chlorine gas.

　　PVDF (polyvinylidene fluoride): resistant to high and low temperature alkali, acid, salt solvents, many solvents such as alcohol, ketones, esters, nitric acid, H2O2, and almost all chemical substances, with a temperature resistance of ≈ 120 ℃, a density of 0.78g/cm3, and a light yellow color.

　　PTFE (polytetrafluoroethylene): It has a very high operating temperature, reduced hardness, low creep resistance, temperature resistance of ≈ 180 ℃, and a milky white color.

　　HDPE (High Density Polyethylene)/PE (Polyethylene): A hard and non flexible plastic that is also suitable for low temperature, low water absorption alkali, acid, salt solvents, and many solvents such as alcohol, ketones, esters. It has a temperature resistance of ≈ 60 ℃, a density of 0.95g/cm3, and a white color.

　　Flame retardant+PP material: Flame retardant materials are materials that can suppress or delay combustion without easily burning themselves, and are widely used in chemical, petroleum and other fields. In recent years, the use of stainless steel distributors in tower internals and packing materials has been introduced in the field of environmental protection to prevent sparks from shallow shooting onto the packing materials during the installation of stainless steel distributors by construction workers.
