Problems solved by technology

[0004] The purpose of the present invention is exactly to overcome and solve the coating in the existing plastic surface smearing hydrophilic coating technology and come off easily in water, is difficult to be practical, or the high polymer monomer that has hydrophilic group is grafted on the surface, High-energy irradiation is difficult to uniformly irradiate the inner and outer surfaces of the filler, resulting in a large difference in the hydrophilicity of the inner and outer surfaces of the filler, and the use effect is poor

Abstract

A process for preparing elastic hydrophilic plastic filler for treating water incldues such steps as proportionally mixing plastic particles of PP, PE or PVC or their mixture, powder of water-solublepolyvinyl alcohol, polyacrylamide, or their mixture, and power of quartz, TiO2, SiO2, or their mixture together, granulating, and shaping filler. Its advantages include simple process, high effect and high reliability.

Description

(1) Technical field: [0001] The invention relates to a method for preparing elastic and hydrophilic plastic fillers for water treatment, which belongs to the processing and preparation technology of polymer material alloys. (two) background technology: [0002] The use of fillers in wastewater biochemical treatment processes is currently being used more and more widely. Checking domestic patents and literature, the contents of fillers for water and wastewater treatment are limited to the shape of fillers, the processing method of fillers, the combination of fibers and plastics in fillers, etc., but there is no information about fillers for water and wastewater treatment. Polymer material content. The condition of the surface of the material has a great relationship with the performance of the filler. Making the surface of the packing hydrophilic is one of the keys to producing high-quality packing for water and wastewater treatment. Making the surface of the material with...
