Kev txhawj xeeb ® HydroxyPropyl methylropy cellulose HPMC cov khoom lag luam tuaj yeem txhim kho los ntawm cov khoom hauv qab no hauv PVC:
· Feem ntau siv cov neeg sawv cev ncua.
· Txheeb xyuas cov particle loj thiab lawv cov xa tawm
Ua rau cov porosity
Txhais cov qhov hnyav ntawm PVC.
Cellulose ether rau polyvinyl chloride (PVC)
Polyvinyl Tshuaj Chloride (PVC) yog kev lag luam thermopiclity polymer dav siv hauv cov khoom siv thiab cov roj ntsha, thiab lwm yam yog lub ntiaj teb thib peb loj tshaj thermoplastic Cov khoom siv los ntawm cov ntim tom qab polyethylene thiab polypropylene.
PVC yog siv dav dav dav dav ntau ntawm kev lag luam ntau yam kev lag luam, kev siv txhua hnub suav nrog kev siv thoob plaws hauv tsev, thauj khoom, siv hluav taws xob / hluav taws xob.
Hauv kev ncua kev kawm Polymerization ntawm Vinyl chloride, cov Dispersed system muaj qhov cuam tshuam ncaj qha rau cov khoom, PVC Resin, thiab ntawm qhov zoo ntawm nws kev ua thiab khoom. Hydroxypropy cog yuav pab txhim kho lub thermal stability ntawm Resin thiab tswj PVC ceev) rau 0.025% ntawm PVC ntau lawm. PVC Resin ua los ntawm cov txiaj ntsig hydroxypropyl me me, tab sis kuj tuaj yeem muaj cov khoom siv ua kom zoo nkauj, tab sis kuj tuaj yeem pom cov khoom sib txawv ntawm cov kev coj ua zoo.
PVC yog cov khoom siv ruaj khov thiab ntev ntev uas tuaj yeem siv rau ntau cov ntawv thov, yog cov tawv nqaij tawv lossis tawv nqaij lossis xim dub thiab xim dub thiab xim dub thiab xim dub
Hauv cov khoom siv hluavtaws, xws li polyvinyl chloride (PVC), polyvinylidene chloride, thiab yuav tsum tau raug tshem tawm hydrothobic monomers tshem tawm hauv dej. Raws li cov dej-soluble polymers, hydroxypropylulose cov khoom muaj cov kev ua haujlwm zoo nkauj thiab ua haujlwm zoo li cov neeg ua haujlwm coloidal. HydroxyPropyyl methylcellulose tuaj yeem tiv thaiv polymeric hais los ntawm kev tsim thiab agglomeration. Tsis tas li ntawd, txawm hais tias hydroxypropal methylropen
