Babban darajar HPMC

PVCdarajar HPMC Hydroxypropyl Methylcellulose shine nau'in polymer tare da mafi yawan amfani da mafi girman aiki tsakanin kowane nau'in cellulose. Ana amfani dashi sosai a fannonin masana'antu daban-daban da rayuwar yau da kullun. An ko da yaushe aka sani da "masana'antu MSG".

Hydroxypropyl methyl cellulose (HPMC) yana ɗaya daga cikin manyan masu rarrabawa a cikin masana'antar polyvinyl chloride (PVC). A lokacin dakatar da polymerization na vinyl chloride, zai iya rage interfacial tashin hankali tsakanin VCM da ruwa da kuma taimaka vinyl chloride monomers (VCM) ne uniformly kuma stably tarwatsa a cikin ruwa matsakaici; yana hana ɗigon VCM daga haɗuwa a farkon matakin tsarin polymerization; yana hana ƙwayoyin polymer daga haɗuwa a ƙarshen mataki na tsarin polymerization. A cikin tsarin dakatarwar polymerization, yana taka rawar tarwatsawa da kariya Matsayin kwanciyar hankali biyu.

A cikin VCM polymerization dakatarwa, farkon polymerization droplets da tsakiya da kuma marigayi polymer barbashi suna da sauki coalesce a farkon, don haka watsawa kariya wakili dole ne a kara da watsawa kare tsarin zuwa VCM dakatar polymerization tsarin. A cikin yanayin ƙayyadaddun hanyar haɗakarwa, nau'in, yanayi da adadin masu rarraba sun zama mahimman abubuwan da za su sarrafa halaye na sassan PVC.

Halaye

(1)Polymerization zafin jiki: A polymerization zafin jiki m kayyade matsakaicin kwayoyin nauyi na PVC, da dispersant m ba shi da wani tasiri a kan kwayoyin nauyi. Gel zafin jiki na mai watsawa ya fi girma fiye da zafin jiki na polymerization don tabbatar da watsawar polymer ta hanyar rarrabawa.

(2) Barbashi halaye: barbashi diamita, ilimin halittar jiki, porosity, da kuma barbashi rarraba ne da muhimmanci Manuniya na SPVC quality, wanda aka alaka da agitator / reactor zane, polymerization ruwa-to-man rabo, watsawa tsarin da karshe hira kudi na VCM, na wanda tsarin watsawa yana da mahimmanci musamman.

(3) Stirring: Kamar tsarin watsawa, yana da tasiri mai girma akan ingancin SPVC. Saboda girman ɗigon VCM a cikin ruwa, saurin motsawa yana ƙaruwa kuma girman digo yana raguwa; lokacin da saurin motsawa ya yi yawa, ɗigon ruwa zai tara kuma ya shafi ɓangarorin ƙarshe.

(4) Tsarin kariyar watsawa: Tsarin kariya yana kare ɗigon VCM a farkon matakin amsawa don guje wa haɗuwa; PVC da aka samar da shi yana haɓaka a cikin ɗigon VCM, kuma tsarin watsawa yana kare haɓakar ƙwayoyin da aka sarrafa, don samun ƙwayoyin SPVC na ƙarshe. An rarraba tsarin watsawa zuwa babban tsarin watsawa da tsarin watsawa na taimako. Babban mai watsawa yana da babban digiri na PVA, HPMC, da dai sauransu, wanda ke shafar aikin SPVC gaba ɗaya; Ana amfani da tsarin watsawa na taimako don inganta wasu halaye na barbashi na SPVC.

(5) Babban tsarin watsawa: Suna da ruwa mai narkewa kuma suna daidaita ɗigon VCM ta hanyar rage tashin hankali tsakanin VCM da ruwa. A halin yanzu a cikin masana'antar SPVC, manyan masu rarraba su ne PVA da HPMC. PVC sa HPMC yana da abũbuwan amfãni daga low sashi, thermal kwanciyar hankali da kuma kyau plasticizing yi na SPVC. Ko da yake yana da ɗan tsada, har yanzu ana amfani da shi sosai. PVC sa HPMC ne mai muhimmanci watsawa kariya wakili a PVC kira.
