I-HPMC E 50
I-EipponCellHPMC E 50 I-Hydroxypropyl methylcellulose iwuhlobo oluvelele lwesisabalalisi esisetshenziswa embonini ye-polyvinyl chloride (PVC).Isetshenziswa ngesikhathi sokumiswa kwe-polymerization ye-vinyl chloride ukuze kuncishiswe ngempumelelo ukungezwani kobuso phakathi kwe-vinyl chloride monomer (VCM) namanzi.Lokhu kuncipha kokushuba kwesimo kusiza ekuhlakazeni ngendlela efanayo nangokuzinza i-VCM endaweni yamanzi.Ukwengeza, kuyasiza ekuvimbeleni ukuhlanganiswa kwamaconsi e-VCM ekuqaleni kwenqubo ye-polymerization futhi kuvimbela ukuhlangana phakathi kwezinhlayiya ze-polymer ezigabeni ezimaphakathi nezakamuva.Ohlelweni lokumiswa kwe-polymerization, i-EipponCellHPMC E 50 Hydroxypropyl methylcellulose isebenzisa inhloso embaxambili yokuvikela ukuhlakazeka nokuzinza.

I-HPMC F 50
I-EipponCellHPMC F 50, i-hydroxypropyl methyl cellulose, isebenza njenge-dispersant embonini ye-PVC.Enqubweni yokumiswa kwe-polymerization ye-vinyl chloride, izisabalalisi ezivame ukusetshenziswa zihlanganisa izinhlanganisela ze-polymer ezifana ne-polyvinyl alcohol ne-cellulose ether.Lapho bengaphansi kokunyakaziswa, benza kube lula ukwakheka kwamaconsi anobukhulu obufanele.Leli khono libizwa ngokuthi ikhono lokuhlakaza le-disperant.Ukwengeza, i-disperant ikhangiswa phezu kwamaconsi e-vinyl chloride monomer, yakhe ungqimba oluvikelayo oluvimbela ukuhlangana kwamaconsi futhi luzinzise.Lo mphumela waziwa ngokuthi ikhono lokugcinwa kwe-colloid le-dispersant.
