Description :
1) Plastic multi-faceted balls/multi-faceted hollow balls Product description:
The reinforced polyhedral hollow sphere produced by Dier Chemical Packing Co., Ltd. in Pingxiang City, Jiangxi Province is made of plastic and consists of two hemispheres combined into a spherical shape. Each hemisphere has 12 semi fan-shaped blades, and the fan-shaped blades of the two hemispheres are staggered from each other. The characteristics of this filler are large specific surface area and high porosity. However, due to the large number of leaves, there is a shielding effect between them, which is not conducive to liquid distribution and wetting; Most liquids gather in hollow cylindrical spheres, hindering the flow of gases and resulting in high resistance. This type of filler is commonly used in water treatment projects. Crude oil vacuum distillation, high vacuum distillation, olefin separation, isomer separation, extraction distillation, etc.
Characteristics: Low pressure drop, high flux, high efficiency, high elasticity, good fluid redistribution performance within the packing layer.

3) Introduction to the characteristics of various plastic materials:
PP (polypropylene): hardness and resistance to bending>PE (polyethylene), but the hardness also decreases when the temperature decreases. It is more resistant to alkali, acid, salt solvents, and many organic 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 ℃. Its density is 0.9-0.92g/cm3 and its color is white;
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 (Poly): 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 poly): 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 very resistant.
PVDF (polyvinylidene fluoride): resistant to high and low temperature alkali, acid, salt solvents, many organic solvents such as alcohol, ketone, ester, etc, ， Almost all chemical substances, such as H2O2, have 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, many organic solvents such as alcohol, ketones, esters, with 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.
Dier Chemical Packing Co., Ltd. in Pingxiang City, Jiangxi Province is a manufacturer that produces and sells three major materials: metal packing, plastic packing, ceramic packing, and tower internal distributors. Our company has signed long-term technical cooperation agreements with more than 10 domestic chemical research units for many years and has hired senior technical management personnel from Tsinghua University and Tianjin to design, process, produce, install, and provide services for our products.
