Polyvinyl Chloride (PVC)

QualiCell Hydroxypropyl Methyl Cellulose HPMC cov khoom tuaj yeem txhim kho los ntawm cov khoom hauv qab no hauv PVC:
· feem ntau siv suspending agents.
· Tswj cov particle loj thiab lawv tis
· Influences lub porosity
· Txhais qhov hnyav ntawm PVC.

Cellulose Ether rau Polyvinyl Chloride (PVC)

Polyvinyl Chloride (PVC) yog ib qho kev lag luam thiab ntau yam thermoplastic polymer dav siv hauv tsev thiab tsim kev lag luam los tsim cov qhov rooj thiab qhov rais, cov kav dej (dej thiab dej khib nyiab), xaim thiab cable rwb thaiv tsev, khoom siv kho mob, thiab lwm yam. Nws yog lub ntiaj teb thib peb loj tshaj plaws thermoplastic. cov khoom los ntawm ntim tom qab polyethylene thiab polypropylene.

PVC yog siv dav hauv ntau yam kev lag luam, kev siv tshuab thiab kev siv niaj hnub suav nrog kev siv dav hauv tsev, thauj, ntim khoom, hluav taws xob / hluav taws xob thiab kev siv kho mob.

Polyvinyl-chloride (PVC)

Nyob rau hauv lub ncua kev kawm ntawv polymerization ntawm vinyl chloride, lub dispersed system muaj ib tug ncaj qha cuam tshuam rau cov khoom, PVC resin, thiab nyob rau hauv lub zoo ntawm nws ua thiab cov khoom.Hydroxypropyl MethylCellulose pab txhim kho cov thermal stability ntawm resin thiab tswj cov particle loj tis (ua lwm yam lus, kho PVC ntom), thiab nws cov nyiaj tso nyiaj rau 0.025% -0.03% ntawm PVC ntau lawm.PVC resin ua los ntawm cov khoom siv zoo Hydroxypropyl MethylCellulose tsis tsuas yog tuaj yeem ua kom cov kab kev ua tau zoo nrog cov qauv thoob ntiaj teb, tab sis kuj tuaj yeem muaj cov khoom zoo ntawm lub cev, cov khoom zoo heev thiab cov cwj pwm zoo rheological.

PVC yog cov khoom siv ruaj khov thiab siv tau ntev heev uas tuaj yeem siv rau ntau yam kev siv, tsis yooj yim los yog hloov tau, dawb lossis dub thiab ntau yam xim nyob nruab nrab.

Hauv kev tsim cov khoom siv hluavtaws, xws li polyvinyl chloride (PVC), polyvinylidene chloride, thiab lwm yam copolymer, ncua kev kawm polymerization yog feem ntau siv thiab yuav tsum yog invariant hydrophobic monomers raug tshem tawm hauv dej.Raws li cov dej-soluble polymers, Hydroxypropyl MethylCellulose khoom muaj kev ua haujlwm zoo heev thiab ua haujlwm ua cov tshuaj tiv thaiv colloidal.Hydroxypropyl MethylCellulose tuaj yeem tiv thaiv cov khoom polymeric los ntawm kev tsim thiab agglomeration.Tsis tas li ntawd, txawm hais tias Hydroxypropyl MethylCellulose yog cov dej soluble polymer, nws tuaj yeem ua rau me ntsis soluble hauv hydrophobic monomers thiab tuaj yeem ua rau cov monomer porosity ntau dua rau kev tsim cov khoom polymeric.
