Polyvinyl Chloride (PVC)

QualiCell Hydroxypropyl Methyl Cellulose Alaabta HPMC waxay ku wanaajin kartaa sifooyinka soo socda ee PVC:
· inta badan la isticmaalo wakiilada laalista.
Waxay xakamaysaa cabbirka walxaha iyo qaybintooda
Waxay saamayn ku yeelataa xuubnimada
Wuxuu qeexayaa culeyska badan ee PVC.

Eter cellulose ee polyvinyl chloride (PVC)

Polyvinyl Chloride (PVC) waa polymer-ka-dhaqaale-dhaqaale ah oo isku dhafan oo si ballaaran loogu isticmaalo dhismaha iyo warshadaha dhismaha si loo soo saaro profiles albaabka iyo daaqadaha, tuubooyinka (cabitaanka iyo biyaha wasakhda ah), daboolka fiilada iyo fiilada, qalabka caafimaadka, iwm. Waa heerkulbeegga saddexaad ee ugu weyn adduunka. maaddada mugga ka dib polyetylen iyo polypropylene.

PVC waxaa si weyn loogu isticmaalaa noocyo kala duwan oo warshado, farsamo iyo codsiyada maalinlaha ah oo ay ku jiraan isticmaalka baahsan ee dhismaha, gaadiidka, baakadaha, korontada/korontada iyo codsiyada daryeelka caafimaadka.

Polyvinyl-chloride (PVC)

Xakamaynta polymerization ee chloride vinyl, nidaamka kala firdhiyey wuxuu saameyn toos ah ku leeyahay badeecada, xabagta PVC, iyo tayada farsamaynteeda iyo alaabteeda.Hydroxypropyl MethylCellulose waxay gacan ka geysataa hagaajinta xasilloonida kulaylka ee xabagta iyo xakamaynta qaybinta cabbirka walxaha (si kale haddii loo dhigo, hagaajin cufnaanta PVC), qaddarkeeduna wuxuu ka dhigan yahay 0.025% -0.03% wax soo saarka PVC.Xabagta PVC ee laga sameeyay tayada sare ee Hydroxypropyl MethylCellulose ma aha oo kaliya inay hubiso xariiqda waxqabadka ee heerarka caalamiga ah, laakiin sidoo kale waxay yeelan kartaa sifooyin muuqaal ah oo muuqda, sifooyin aad u fiican iyo dabeecad dhalaaleed oo heer sare ah.

PVC waa shay aad u waara oo waara kaas oo loo isticmaali karo codsiyo kala duwan, ha ahaato mid adag ama dabacsan, caddaan ama madow iyo midabyo kala duwan oo u dhexeeya.

Soo saarista xabagta synthetic, sida polyvinyl chloride (PVC), chloride polyvinylidene, iyo copolymers kale, polymerization hakinta ayaa ah tan ugu badan ee la isticmaalo waana inay noqotaa monomers hydrophobic-ka ah oo aan kala sooc lahayn oo ku xayiran biyaha.Sida polymers-ka biyaha ku milma, alaabada Hydroxypropyl MethylCellulose waxay leedahay firfircooni dusha sare oo aad u fiican waxayna u shaqeysaa sida wakiilada kolloidalka ah ee ilaaliya.Hydroxypropyl MethylCellulose waxay si wax ku ool ah uga hortagi kartaa walxaha polymeric soo saarista iyo kicinta.Intaa waxaa dheer, in kasta oo Hydroxypropyl MethylCellulose uu yahay polymerka biyaha ku milma, waxay noqon kartaa wax yar oo ku milma monomers hydrophobic waxayna kordhin kartaa porosity monomer ee soo saarista qaybaha polymeric.
