Embodiment Construction

[0013] The present invention can be explained in detail through the following examples, and the purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0014] The invention provides a filter material, which is a special filter material for purification of biological preparations, which is characterized in that it includes a layer of base cloth 1 woven from polyphenylene sulfide and polyacrylonitrile blended yarns. The upper and lower surfaces of the cloth 1 are symmetrically pasted with a fiber layer 2 by a needling machine, and the fiber layer 2 is composed of glass fiber chopped strands and polyaluminum chloride / polyaluminum ferric chloride / polyacrylamide / polyferric sulfate; PTFE liquid impregnation 3 is compounded on the dust-facing surface; PTFE scraping film 4 is compounded on the outer surface of the PTFE liquid impregnation. The dust-facing surface and the base cloth 1 are connected by symmetrical...

Abstract

The invention discloses a special filter material for purifying a biological agent. The special filter material comprises one layer of base cloth woven from polyphenylene sulfide and polyacrylonitrile blended yarns, fiber layers are symmetrically pasted on the upper surface and lower surface of the base cloth by adopting a needle machine, the fiber layers are composed of glass fiber short-cut yarns and polymeric aluminum / polyaluminum ferric chloride / polyacrylamide / polymeric ferric sulfate; a PTFE (Poly Tetra Fluoro Ethylene) liquid is compounded on a dust-facing surface and used for dipping the dust-facing surface; a PTFE scraping film is compounded on the dipped outer surface of the PTFE liquid. By adopting the base cloth woven from the polyphenylene sulfide and polyacrylonitrile blended yarns, the filter material is high in power, and good in size stability; the fiber layer is formed by adopting the glass fiber short-cut yarns and the polymeric aluminum / polyaluminum ferric chloride / polyacrylamide / polymeric ferric sulfate, so that a good filtering effect is achieved for a biological purifying process.

Description

technical field [0001] The invention relates to the technical field of filter materials, in particular to a special filter material for purification of biological preparations. Background technique [0002] Biological preparations, as the name suggests, refer to the effective biological ingredients extracted from living organisms or their products, and continue to be processed into medicines or health care products. In recent years, countries around the world have begun to vigorously research and develop biological agents in order to find drugs to solve some refractory diseases and to maintain health care. According to a research report in Taiwan, from 1998 to 2007, the share of biological agents in the drug market soared from 4.4% to 10.5%, creating a miracle of rapid growth. However, due to the high cost of biological preparations, the requirements for purity and production process are relatively high. Contents of the invention [0003] In order to reduce the requireme...
