Plastic Rasch ring is a bulk packing. The shape is simple. It is a circle whose height is equal to its diameter. Laci ring has excellent acid and heat resistance, can resist all kinds of inorganic acids, organic acids and organic solvents except hydrofluoric acid corrosion, can be used in a variety of high temperature occasions. Plastic Lassie ring fillers are simple rings of equal height and diameter shape. Plastic Rasi ring packing according to the material is mainly divided into: polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), chlorinated polyvinyl chloride (CPVC), reinforced polypropylene (RPP) and so on. According to different requirements, the material used is different, the commonly used PP Rasi ring, PVC Rasi ring, RPP Rasi ring and so on. Plastic Rasi ring packing application range is very wide, can be used in chemical, metallurgy, gas, environmental protection and other industries of drying tower, absorption tower, cooling tower, washing tower, regeneration tower.
● Plastic Rasi ring is the earliest annular packing with fixed geometry in the history of tower packing. The characteristic of Rasi ring is that the outer diameter and height of the packing ring are equal
● Simple structure, low price, but the existence of uneven liquid distribution and serious wall flow trench flow and other phenomena.
● corrosion resistance can also resist aqua regia and all organic solvents; The best aging life of weather-resistant plastics; High lubrication with plastic medium to small friction coefficient (0.04); Having a medium to small surface tension of a solid material without adhering to anything; It has physiological inertia; Excellent electrical performance, is the ideal C class insulation material. Widely used in defense industry, atomic energy, petroleum, radio, electric power machinery, chemical industry and other important departments.
