PVC Ibanga HPMC
I-PVCI-HPMC Hydroxypropyl Methylcellulose iwuhlobo lwe-polymer olusetshenziswa kakhulu futhi lusebenza kakhulu phakathi kwazo zonke izinhlobo ze-cellulose. Isetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni kanye nempilo yansuku zonke. Bekulokhu kwaziwa ngokuthi “i-MSG yezimboni”.
IHydroxypropyl methyl cellulose (HPMC) ingesinye sezisabalalisi eziyinhloko embonini ye-polyvinyl chloride (PVC). Ngesikhathi sokumiswa kwe-polymerization ye-vinyl chloride, inganciphisa ukungezwani kobuso phakathi kwe-VCM namanzi futhi isize i-vinyl chloride monomers (VCM) ihlakazeke ngokufanayo futhi ihlakazeke ngokuzinzile endaweni enamanzi; ivimbela amaconsi e-VCM ekuhlanganeni esigabeni sokuqala senqubo ye-polymerization; ivimbela izinhlayiya ze-polymer ekuhlanganeni esigabeni sakamuva senqubo ye-polymerization. Kuhlelo lokumiswa kwe-polymerization, idlala indima yokuhlakazeka nokuvikela Iqhaza elikabili lokuzinza.
Ku-polymerization yokumiswa kwe-VCM, amaconsi okuqala e-polymerization kanye nezinhlayiya ze-polymer ezimaphakathi nezakamuva kulula ukuhlangana ekuqaleni, ngakho-ke i-ejenti yokuvikela ukuhlakazeka kufanele yengezwe ohlelweni lwe-polymerization yokumiswa kwe-VCM. Endabeni yendlela yokuxuba ehleliwe, uhlobo, imvelo kanye nenani le-dispersant libe yizici ezibalulekile zokulawula izici zezinhlayiya ze-PVC.

Izici
(1)Izinga lokushisa le-polymerization: Izinga lokushisa le-polymerization ngokuyisisekelo linquma isilinganiso sesisindo samangqamuzana e-PVC, futhi i-disperant ngokuyisisekelo ayinawo umthelela esisindweni samangqamuzana. Izinga lokushisa lejeli le-disperant liphakeme kunezinga lokushisa le-polymerization ukuqinisekisa ukuhlakazeka kwe-polymer yi-dispersant.
(2) Izici zezinhlayiya: ububanzi bezinhlayiya, i-morphology, i-porosity, kanye nokusatshalaliswa kwezinhlayiyana kuyizinkomba ezibalulekile zekhwalithi ye-SPVC, ehlobene nomklamo we-agitator/reactor, isilinganiso se-polymerization yamanzi-to-oyela, uhlelo lokuhlakazeka kanye nezinga lokugcina lokuguqulwa kwe-VCM, okuyinto uhlelo lokuhlakazeka olubaluleke ngokukhethekile .
(3) Ukunyakazisa: Njengesistimu yokusabalalisa, kunomthelela omkhulu kukhwalithi ye-SPVC. Ngenxa yobukhulu bamaconsi e-VCM emanzini, isivinini esishukumisayo siyakhula futhi usayizi we-droplet uyancipha; lapho isivinini esishukumisayo siphezulu kakhulu, amaconsi azohlangana futhi athinte izinhlayiya zokugcina.
(4) Uhlelo lokuvikela ukuhlakazeka: Uhlelo lokuvikela luvikela amaconsi e-VCM esigabeni sokuqala sokusabela ukuze kugwenywe ukuhlangana; i-PVC ekhiqiziwe idlula kumaconsi e-VCM, futhi uhlelo lokusabalalisa luvikela i-agglomeration yezinhlayiya ezilawulwayo, ukuze kutholwe izinhlayiya zokugcina ze-SPVC. Uhlelo lokuhlakazeka luhlukaniswe uhlelo oluyinhloko lokuhlakazeka kanye nohlelo olusizayo lokuhlakazeka. I-disperant eyinhloko ine-high alcoholysis degree PVA, HPMC, njll., ethinta ukusebenza okuphelele kwe-SPVC; isistimu yokusabalalisa eyisiza isetshenziselwa ukuthuthukisa izici ezithile zezinhlayiya ze-SPVC.
(5) Uhlelo oluyinhloko lokuhlakazeka: Ayakwazi ukuncibilika emanzini futhi azinzisa amaconsi e-VCM ngokunciphisa ukungezwani phakathi kobuso phakathi kwe-VCM namanzi. Njengamanje embonini ye-SPVC, ama-disperants amakhulu yi-PVA ne-HPMC. I-PVC yebanga le-HPMC inezinzuzo zomthamo ophansi, ukuzinza okushisayo nokusebenza okuhle kwe-plasticizing kwe-SPVC. Nakuba ibiza kakhulu, isasetshenziswa kabanzi. I-PVC grade HPMC iyi-ejenti ebalulekile yokuvikela ukuhlakazwa ekuhlanganiseni kwe-PVC.
