Abstract

The invention discloses a production process for a sewage filter net used for adsorbing harmful substances in sewage. The production process comprises the following steps that raw materials used for producing the net are prepared; high-viscosity polyester chips and polyurethane fibers are heated under a high temperature, nano glass fibers and additives are added, uniform stirring is conducted, and mixed glue stock A is obtained; adsorbent resin, ion exchange resin and nano activated carbon are heated and stirred under a high temperature uniformly, so that mixed glue stock B is obtained; the mixed glue stock A and the mixed glue stock B are subjected to spinning through a melt spinning machine, and industrial filaments C and industrial filaments D are manufactured; and the industrial filaments C and the industrial filaments D are manufactured into composite filaments, and the filter net is woven by means of the composite filaments. The production process provided by the invention is easy to operate and low in production cost; the prepared sewage filter net is good in acid-base resistance, ageing resistance and high-temperature resistance, long in service life, high in adsorptivity, capable of effectively adsorbing the harmful substances in the sewage and achieving separation and purification, easy to clean, and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a production process of a sewage filter net for absorbing harmful substances in sewage. Background technique [0002] The paper industry is an industry that manufactures various types of paper products and is closely related to the development of the national economy. It involves forestry, agriculture, machinery manufacturing, chemicals, electrical automation, transportation, environmental protection and other industries. The paper industry uses wood, straw, reeds, rags, etc. as raw materials, and cellulose is separated by high-temperature and high-pressure cooking to make pulp. In the papermaking process, a lot of papermaking wastewater will be produced, which is extremely harmful, seriously pollutes water sources, and poses a serious threat to the ecological environment and human health. [0003] Polyester (PET) is a polymer compound. Fiber-grade polyester chips are...
