Iimveliso ze-Hydroxypropyl Methyl Cellulose zinokusetyenziswa kakhulu kwindawo yokumisa i-polymerization ye-vinyl chloride e-China. Kwi-polymerization yokumiswa kwe-vinyl chloride, inkqubo ehlakaziweyo inefuthe elithe ngqo kwimveliso, i-PVC resin, kunye nomgangatho wokwenziwa kwayo kunye neemveliso. IHydroxypropylMethylCellulose inceda ekuphuculeni uzinzo lwe-thermal ye-resin kunye nokulawula ukuhanjiswa kobungakanani besuntswana.I-resin ye-PVC eyenziwe kwikhwalithi ephezulu ye-HydroxypropylMethylCellulose ayinakuqinisekisa kuphela umgca wokusebenza kunye nemigangatho yamazwe ngamazwe, kodwa ingaba neepropati ezibonakalayo ezibonakalayo ezibonakalayo, iipropati ezigqwesileyo zamasuntswana kunye nokuziphatha okugqwesileyo okunyibilika kwerheological.
Kwimveliso yeerasi zokwenziwa, ezifana ne-polyvinyl chloride, i-polyvinylidene chloride, kunye nezinye ii-copolymers, i-suspension polymerization yeyona isetyenziswa kakhulu kwaye kufuneka ibe yi-hydrophobic monomers engaguqukiyo enqunyanyiswe emanzini. Njengeepolymers ezinyibilikayo emanzini, imveliso ye-HydroxypropylMethylCellulose inomsebenzi ogqwesileyo womhlaba kunye nemisebenzi njenge-colloidal agents ezikhuselayo. I-HydroxypropylMethylCellulosecan ikhusela ngokufanelekileyo amasuntswana e-polymeric ekuveliseni kunye ne-agglomeration. Ngaphaya koko, nangona iHydroxypropylMethylCelluloseis iyipolymer enyibilikayo yamanzi, inokunyibilika kancinane kwiimonomers ze-hydrophobic kwaye inokonyusa i-monomer porosity yokuveliswa kwamasuntswana epolymeric.
Ukongeza, izifundo zibonise ukuba kwinkqubo yokuvelisa i-PVC, amashishini ahlukeneyo asebenzisa inkqubo ehlukeneyo, ngoko ke iipropati zokugqoka zangaphandle ze-PVC eziveliswayo nazo zahlukile, kwaye ngaloo ndlela i-HydroxypropylMethylCellulose inokuchaphazela ukusebenza kwe-resin ye-PVC. Kwinkqubo ye-agent edibeneyo yokusabalalisa, i-resin ye-PVC yokumiswa elungiselelwe kwi-agent edibeneyo yokusabalalisa i-polyvinyl alcohol (PVA) ene-alcoholic ehlukeneyo kunye needigri ze-polymerization kunye ne-hydroxypropyl methyl cellulose (HPMC) ingaba nemiphumo eyahlukileyo ekusebenzeni kokusebenza. Uvavanyo lubonise ukuba ikhompawundi HydroxypropylMethylCellulose kunye KP-08/KZ-04 kunye isidanga alcoholysis 68% -75% ngcono kwaye kwakhona inzuzo porosity resin kunye nokufunxa plasticizers.
