PVC QIB HPMC
PvcQib HPMC HydroxyPropyyl methylulose yog cov polymer yog ntau yam nrog cov feem ntau siv thiab kev ua tau zoo tshaj plaws ntawm txhua yam ntawm txhua hom cellulose. Nws yog dav siv nyob rau hauv ntau yam kev lag luam thiab lub neej txhua hnub. Nws ib txwm tau hu ua "Industrial MSG".
HydroxyPropy cellulose (HPMC) yog ib qho ntawm cov neeg tsis sib xws hauv cov polyvinyl chloride (PVC) kev lag luam. Thaum lub sij hawm kev ncua qib polymerization ntawm vinyl chloride, nws tuaj yeem txo cov nro hauv vcm ntawm vcm thiab pab viscyl chloride monomers (VCM) yog unifabed dispersed thiab inqueeous nruab nrab; Tiv thaiv vcm teeple los ntawm kev sib koom ua ke nyob rau theem pib ntawm cov txheej txheem polymerization; Tiv thaiv cov polymer hais los ntawm kev sib koom ua ke hauv cov theem ntawm cov txheej txheem polymerization. Hauv kev ncua kev kawm Polymerization system, nws plays lub luag haujlwm ntawm kev tawg thiab kev tiv thaiv lub luag haujlwm ntawm kev ruaj khov.
Hauv VCM raug ncua polymerization, thaum ntxov polymerization tee yog yooj yim rau Coalesce yuav tsum tau ntxiv rau cov kev ncua VCM kev ncua. Xws li cov qauv sib xyaw ua ke, hom, xwm thiab tus nqi ntawm dispersant tau ua cov yam ntxwv tseem ceeb los tswj tus yam ntxwv ntawm PVC tawm.

Cov yam ntxwv
(1)Polymerization kub: Qhov hnyav kub yog txiav txim siab qhov nruab nrab molecular hnyav ntawm pvc, thiab cov dispersant yeej tsis muaj qhov cuam tshuam ntawm cov molecular hnyav. Qhov kub thiab txias ntawm cov neeg tsis sib luag yog siab dua li cov polymerization kub kom ntseeg tau tias cov dispersion ntawm cov polymer los ntawm qhov tsis sib luag.
(2) Cov yam ntxwv particle: partple uas hla, thiab kev faib tawm cov roj ntsha / cov tshuaj tiv thaiv kab mob, thiab hloov pauv ntawm VCM, ntawm Qhov twg dispersion system yog qhov tshwj xeeb tshaj yog ib qho tseem ceeb.
(3) Stirring: Zoo li kev rho tawm system, nws muaj qhov cuam tshuam zoo rau qhov zoo ntawm SPVC. Vim tias qhov loj me ntawm VCM cov tee dej hauv dej, qhov ceev ceev nce thiab cov tee loj loj qis; Thaum lub nrawm nrawm dhau lawm, cov tee dej yuav sib sau ua ke thiab cuam tshuam cov lus kawg.
(4) Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv: Cov kev tiv thaiv kev tiv thaiv tiv thaiv VCM Doplots nyob rau hauv lub sijhawm thaum ntxov ntawm kev tawm tsam kom tsis txhob muaj kev sib koom ua ke; Cov tsim tawm PVC precipitates hauv VCM tee, thiab kev faib tawm cov txheej txheem tiv thaiv lub agglomeration, yog li kom tau txais qhov kawg SPVC siv. Qhov system dispersion tau muab faib ua lub ntsiab dispersion thiab cov pab cuam tshuam kev cuam tshuam. Qhov tseem ceeb tsis meej dhau los muaj kev ua kom muaj dej cawv kom siab, HPMC, thiab lwm yam, uas cuam tshuam rau tag nrho kev ua haujlwm ntawm SPVC; Ntu kev dispersing system yog siv los txhim kho qee yam yam ntxwv ntawm SPVC cov lus.
(5) Lub ntsiab lus tseem ceeb: lawv yog cov dej-soluble thiab ruaj khov lub vcm teeple los ntawm kev txo cov kev cuam tshuam ntawm vcm thiab dej. Tam sim no nyob rau hauv SPVC kev lag luam, lub ntsiab dispersants yog PVA thiab HPMC. PVC QIB HPMC muaj qhov zoo ntawm cov tshuaj tsawg, thermal stability, thermal ruaj khov thiab zoo yas ua kev ua tau zoo ntawm SPVC. Txawm hais tias nws yog tus nqi kim, nws tseem siv dav. PVC QIB HPM yog ib qho tseem ceeb disgersion kev tiv thaiv tus neeg sawv cev hauv PVC synthesis.
