Acid and alkali resistant filler PVC 84 inner arc ring filler

Acid and alkali resistant filler PVC 84 inner arc ring fillerAlso known as polyvinyl chloride 84 inner arc ring. Using raw material polyvinyl chloride, abbreviated as PVC in English, it is divided into soft and hard polyvinyl chloride. Soft products are soft and tough, with a sticky touch, while hard products have a hardness higher than low-density polyethylene and lower than polypropylene. Whitening occurs at the bending point. Polyvinyl chloride stability; Not easily corroded by acid and alkali; Relatively tolerant to heat. Polyvinyl chloride has the advantages of flame retardancy (with a flame retardant value of over 40), high chemical resistance (resistant to concentrated hydrochloric acid, sulfuric acid with a concentration of 90%, nitric acid with a concentration of 60%, and sodium hydroxide with a concentration of 20%), and good mechanical strength. The softening point of polyvinyl chloride is 80 ℃.

Acid and alkali resistant filler PVC 84 inner arc ring fillerIt is a new type of high-efficiency plastic bulk packing material with reasonable geometric symmetry, good structural uniformity, and high porosity. The eight arc ring and four arc ring are arranged alternately in the axial direction, and each arc segment is folded radially inward into the ring, so that the surface of the packing material is continuous and evenly distributed in space. Compared with the Bauer ring, the flux can be increased by 15-30% and the pressure drop can be reduced by 20-30%.

The plastic 84 inner arc rings produced by our company are made of materials other than polyvinyl chloride (PVC), including polyethylene (PE), reinforced polypropylene (RPP), polyvinylidene fluoride (PVDF), chlorinated polyvinyl chloride (CPVC), polytetrafluoroethylene (PTFE), and polyvinylidene fluoride (PVDF), which can be selected according to the requirements of the packing tower medium, temperature, pressure, and service life. The specific surface area of the 84 inner arc ring packing is the packing surface area per unit volume of the packing layer, usually expressed as a and measured in m2/m
