PVC ọkwa HPMC

PVCọkwa HPMC Hydroxypropyl Methylcellulose bụ polymer dị iche iche nwere ọtụtụ ojiji yana arụmọrụ kachasị elu n'etiti ụdị cellulose niile. A na-eji ya n'ọtụtụ ebe na mpaghara mmepụta ihe dị iche iche na ndụ kwa ụbọchị. A na-akpọkarị ya "MSG ụlọ ọrụ".

Hydroxypropyl methyl cellulose (HPMC) bụ otu n'ime ndị na-ekesa isi na ụlọ ọrụ polyvinyl chloride (PVC). N'oge nkwusioru polymerization nke vinyl chloride, ọ nwere ike ibelata interfacial esemokwu n'etiti VCM na mmiri na-enyere vinyl chloride monomers (VCM) na-unimes na stably chụsasịrị na aqueous ọkara; na-egbochi ụmụ irighiri mmiri VCM ka ha jikọta na mmalite nke usoro polymerization; na-egbochi ụmụ irighiri ihe ndị polymer ka ha jikọta na njedebe nke usoro polymerization. N'ime usoro nkwusioru polymerization, ọ na-arụ ọrụ nke mgbasa ozi na nchebe Ọrụ abụọ nke nkwụsi ike.

N'ime polymerization nkwusioru VCM, ụmụ irighiri mmiri polymerization nke mbụ na nke etiti na mbubreyo polymer dị mfe ijikọ ọnụ na mbido, yabụ, a ga-agbakwunye onye na-ahụ maka nchekwa mgbasa na sistemụ polymerization VCM nkwusioru. N'ihe banyere usoro ngwakọta edozi, ụdị, ọdịdị na ọnụọgụ nke mgbasa ozi aghọwo isi ihe na-achịkwa njirimara nke ihe ndị dị na PVC.

Njirimara

(1)Polymerization okpomọkụ: The polymerization okpomọkụ isi na-ekpebi nkezi molekụla arọ nke PVC, na dispersant ihu ọma enweghị mmetụta na molekụla arọ. The gel okpomọkụ nke dispersant dị elu karịa polymerization okpomọkụ iji hụ na mgbasa nke polymer site dispersant.

(2) urughuru e ji mara: urughuru dayameta, morphology, porosity, na urughuru nkesa bụ ihe dị mkpa na-egosi nke SPVC àgwà, nke metụtara agitator / reactor imewe, polymerization mmiri na-mmanụ ruru, dispersion usoro na ikpeazụ ntọghata ọnụego nke VCM, nke nke usoro mgbasa ozi dị mkpa karịsịa.

(3) Na-akpali akpali: Dị ka usoro mgbasa ozi, ọ na-enwe mmetụta dị ukwuu na àgwà SPVC. N'ihi nha nke VCM ụmụ irighiri mmiri n'ime mmiri, ọsọ na-akpali akpali na-abawanye na nha droplet na-ebelata; mgbe ọsọ na-akpali akpali dị oke elu, ụmụ irighiri mmiri ga-agbakọta ma na-emetụta akụkụ ikpeazụ.

(4) Usoro nchebe mgbasa ozi: Usoro nchebe na-echebe ụmụ irighiri mmiri VCM na mmalite nke mmeghachi omume iji zere ijikọta; PVC emepụtara na-ebuli n'ime mmiri VCM, na usoro mgbasa ozi na-echebe agglomeration nke ihe ndị a na-achịkwa, ka ha wee nweta ihe ikpeazụ SPVC. A na-ekewa usoro mgbasa ozi n'ime usoro mgbasa ozi bụ isi na usoro mgbasa ozi inyeaka. Onye na-ekesa isi nwere ogo mmanya mmanya dị elu PVA, HPMC, wdg, nke na-emetụta arụmọrụ SPVC n'ozuzu ya; A na-eji usoro mgbasa ozi inyeaka iji melite ụfọdụ njirimara nke irighiri ihe SPVC.

(5) Usoro mgbasa ozi bụ isi: Ha na-agbaze mmiri ma na-eme ka ụmụ irighiri mmiri VCM guzosie ike site n'ibelata esemokwu interfacial n'etiti VCM na mmiri. Ugbu a na ụlọ ọrụ SPVC, ndị na-ekesa isi bụ PVA na HPMC. PVC ọkwa HPMC nwere uru nke ala onunu ogwu, thermal kwụsie ike na ezi plasticizing arụmọrụ nke SPVC.
