PVC Grade HPMC
PVCgrade HPMC Hydroxypropyl Methylcellulose ke mofuta oa polymer o nang le ts'ebeliso e ngata le ts'ebetso e phahameng ka ho fetisisa har'a mefuta eohle ea selulose. E sebelisoa haholo libakeng tse fapaneng tsa indasteri le bophelong ba letsatsi le letsatsi. Haesale e tsejoa e le "MSG ea indasteri".
Hydroxypropyl methyl cellulose (HPMC) ke e 'ngoe ea li- dispersants tse ka sehloohong indastering ea polyvinyl chloride (PVC). Nakong ea ho fanyeha polymerization ea vinyl chloride, e ka fokotsa tsitsipano ea sefahleho pakeng tsa VCM le metsi le ho thusa vinyl chloride monomers (VCM) ka mokhoa o ts'oanang le ka mokhoa o tsitsitseng o qhalakantsoeng sebakeng se nang le metsi; e thibela marotholi a VCM hore a se ke a kopana sethaleng sa pele sa polymerization; e thibela likaroloana tsa polymer ho kopana qetellong ea mokhoa oa polymerization. Sistimi ea polymerization ea ho emisoa, e bapala karolo ea ho hasana le ts'ireletso Karolo e 'meli ea botsitso.
Ka VCM suspension polymerization, marotholi a pele a polymerization le likaroloana tsa polymer tse bohareng le tsa morao li bonolo ho kopana qalong, kahoo moemeli oa ts'ireletso ea ts'ireletso o tlameha ho kenngoa tsamaisong ea polymerization ea VCM. Tabeng ea mokhoa o tsitsitseng oa ho kopanya, mofuta, tlhaho le palo ea dispersant li fetohile lintlha tsa bohlokoa ho laola litšobotsi tsa likaroloana tsa PVC.

Litšobotsi
(1)Mocheso oa mocheso oa polymerization: Thempereichara ea polymerization ha e le hantle e etsa qeto ea boima ba limolek'hule tsa PVC, 'me dispersant ha e le hantle ha e na phello ho boima ba molek'hule. Mocheso oa gel oa dispersant o phahame ho feta mocheso oa polymerization ho etsa bonnete ba ho hasana ha polymer ke dispersant.
(2) Litšobotsi tsa likaroloana: bophara ba likaroloana, morphology, porosity, le phallo ea likaroloana ke matšoao a bohlokoa a boleng ba SPVC, tse amanang le moralo oa agitator / reactor, polymerization ea metsi ho ea ho oli, tsamaiso ea ho hasana le tekanyo ea ho qetela ea phetoho ea VCM, ea eo tsamaiso ea ho hasana e leng ea bohlokoa ka ho khetheha .
(3) Ho hlohlelletsa: Joaloka tsamaiso ea ho hasana, e na le tšusumetso e kholo ho boleng ba SPVC. Ka lebaka la boholo ba marotholi a VCM ka metsing, lebelo le tsosang le eketseha 'me boholo ba marotholi bo fokotseha; ha lebelo le tsosang le phahame haholo, marotholi a tla bokellana 'me a ama likaroloana tsa ho qetela.
(4) Tsamaiso ea ts'ireletso ea ho hasana: Mokhoa oa tšireletso o sireletsa marotholi a VCM nakong ea pele ea karabelo ho qoba ho kopana; PVC e hlahisoang e fokotseha ka marotholi a VCM, 'me tsamaiso ea ho hasana e sireletsa ho bokellana ha likaroloana tse laoloang, e le ho fumana likaroloana tsa ho qetela tsa SPVC. Tsamaiso ea ho hasana e arotsoe ka mokhoa o ka sehloohong oa ho hasana le mokhoa o thusang oa ho hasana. The dispersant e ka sehloohong e na le tekanyo e phahameng ea alcoholysis PVA, HPMC, joalo-joalo, e amang ts'ebetso ea kakaretso ea SPVC; Sistimi e thusang ea ho qhalakanya e sebelisoa ho ntlafatsa litšobotsi tse ling tsa likaroloana tsa SPVC.
(5) Mokhoa o ka sehloohong oa ho hasana: Ha o na metsi 'me o tsitsisa marotholi a VCM ka ho fokotsa tsitsipano pakeng tsa VCM le metsi. Hajoale indastering ea SPVC, li- dispersants tse ka sehloohong ke PVA le HPMC. PVC grade HPMC e na le melemo ea litekanyetso tse tlase, botsitso ba mocheso le ts'ebetso e ntle ea polasetiki ea SPVC. Le hoja e batla e le theko e boima, e ntse e sebelisoa haholo. PVC kereiti ea HPMC ke moemeli oa bohlokoa oa ts'ireletso ea ho hasana ka har'a motsoako oa PVC.
