Ibanga le-PVC le-HPMC
I-PVCI-HPMC Hydroxypropyl Methylcellulose yebanga le-HPMC Hydroxypropyl Methylcellulose iyinhlobo ye-polymer esetshenziswa kakhulu futhi esebenza kahle kakhulu phakathi kwazo zonke izinhlobo ze-cellulose. Isetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni kanye nokuphila kwansuku zonke. Ibilokhu yaziwa ngokuthi “i-industrial MSG”.
I-Hydroxypropyl methyl cellulose (HPMC) ingenye yezinto ezihlukanisayo embonini ye-polyvinyl chloride (PVC). Ngesikhathi sokumiswa kwe-vinyl chloride, kunganciphisa ukungezwani kokuxhumana phakathi kwe-VCM namanzi futhi kusize ama-monomers e-vinyl chloride (VCM) ukuthi ahlakazeke ngokulinganayo nangokuzinzile endaweni enamanzi; kuvimbela amaconsi e-VCM ukuthi ahlangane esigabeni sokuqala senqubo ye-polymerization; kuvimbela izinhlayiya ze-polymer ukuthi zihlangane esigabeni sokugcina senqubo ye-polymerization. Ohlelweni lwe-polymerization lokumiswa, ludlala indima yokuhlakazeka nokuvikela. Indima ephindwe kabili yokuzinza.
Ku-polymerization yokumiswa kwe-VCM, amaconsi okuqala e-polymerization kanye nezinhlayiya ze-polymer eziphakathi naphakathi nesikhathi esiphelile kulula ukuhlangana ekuqaleni, ngakho-ke i-ejenti yokuvikela ukuhlakazeka kumele ifakwe ohlelweni lwe-polymerization yokumiswa kwe-VCM. Uma kwenzeka indlela yokuxuba engaguquki, uhlobo, uhlobo kanye nenani le-dispersant kube yizinto ezibalulekile zokulawula izici zezinhlayiya ze-PVC.

Izici
(1)Izinga lokushisa le-polymerization: Izinga lokushisa le-polymerization ngokuyisisekelo linquma isisindo sama-molecule esimaphakathi se-PVC, kanti i-dispersant ngokuyisisekelo ayinawo umthelela esisindweni sama-molecule. Izinga lokushisa lejeli le-dispersant liphakeme kunezinga lokushisa le-polymerization ukuqinisekisa ukusabalala kwe-polymer yi-dispersant.
(2) Izici zezinhlayiya: ububanzi bezinhlayiya, ukuma kwazo, ukuvuleka kwazo, kanye nokusatshalaliswa kwezinhlayiya kuyizinkomba ezibalulekile zekhwalithi ye-SPVC, ezihlobene nomklamo we-agitator/reactor, isilinganiso samanzi-kuya-oyela esilinganisweni se-polymerization, uhlelo lokusabalala kanye nesilinganiso sokugcina sokuguqulwa kwe-VCM, lapho uhlelo lokusabalala lubaluleke kakhulu khona.
(3) Ukuxuba: Njengesistimu yokusabalalisa, kunomthelela omkhulu kwikhwalithi ye-SPVC. Ngenxa yobukhulu bamaconsi e-VCM emanzini, isivinini sokuxuba siyanda futhi usayizi wamaconsi uyancipha; lapho isivinini sokuxuba 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 ekhiqizwayo ingena emaconsi e-VCM, kanti uhlelo lokusabalalisa luvikela ukuhlangana kwezinhlayiya ezilawulwayo, ukuze kutholakale izinhlayiya zokugcina ze-SPVC. Uhlelo lokusabalalisa luhlukaniswe uhlelo lokusabalalisa oluyinhloko kanye nohlelo lokusabalalisa olusizayo. I-dispersant eyinhloko inezinga eliphezulu le-alcoholization PVA, HPMC, njll., ezithinta ukusebenza kwe-SPVC iyonke; uhlelo lokusabalalisa olusizayo lusetshenziselwa ukuthuthukisa ezinye izici zezinhlayiya ze-SPVC.
(5) Uhlelo oluyinhloko lokusabalala: Ancibilika emanzini futhi azinzisa amaconsi e-VCM ngokunciphisa ukungezwani phakathi kwe-VCM namanzi. Njengamanje embonini ye-SPVC, ama-dispersant amakhulu yi-PVA ne-HPMC. I-HPMC yebanga le-PVC inezinzuzo zomthamo ophansi, ukuzinza kokushisa kanye nokusebenza kahle kwe-SPVC ngepulasitiki. Nakuba ibiza kakhulu, isasetshenziswa kabanzi. I-HPMC yebanga le-PVC iyisivikelo esibalulekile sokusabalala ekuhlanganisweni kwe-PVC..
