The outer diameter of hollow fiber is 0.4-2.0mm, the inner diameter is 0.3-1.4mm, and the wall of hollow fiber tube is covered with microholes, and the pore size can be expressed by the molecular weight of the intercepted material, and the molecular weight of the intercepted material can reach thousands to hundreds of thousands. In the function of hollow fiber membrane, the pore diameter and size of the membrane are closely related to the pore-making agent. At present, PVPK30 is the most used. As a better pore-causing agent, PVPK30 mainly affects the pore structure from two factors: thermodynamics and kinetics. Thermodynamics affects the pore structure When the content of PVPK30 in the casting liquid is low, the influence of thermodynamic factors becomes the dominant factor. The addition of PVPK30 reduces the thermodynamic stability of the casting\u2026<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[79],"attr":[],"class_list":["post-1083","post","type-post","status-publish","format-standard","hentry","category-problems","tag-polyvinylpyrrolidone"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1083","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/comments?post=1083"}],"version-history":[{"count":2,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1083\/revisions"}],"predecessor-version":[{"id":1086,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1083\/revisions\/1086"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=1083"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=1083"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=1083"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=1083"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
