Zvigadzirwa zveHydroxypropyl Methyl Cellulose zvinoshandisa zvakanyanya vinyl chloride muChina. Mukushandiswa kwevinyl chloride mukumiswa, system yakapararira ine simba rakananga pakugadzirwa, PVC resin, uye pamhando yekugadzirwa kwayo uye zvigadzirwa. HydroxypropylMethylCellulose inobatsira kuvandudza kugadzikana kwekupisa kweresin uye kudzora kupararira kwehukuru hwezvikamu..PVC resin yakagadzirwa neHydroxypropylMethylCellulose yepamusoro-soro haingogone chete kuve nechokwadi chekuti inoshanda zvinoenderana nezvinodiwa zvepasi rose, asiwo inogona kuva nehunyanzvi hwakanaka, hunhu hwakanaka hwezvikamu uye hunhu hwakanaka hwekunyungudutsa kwetsinga.
Mukugadzirwa kwemasinisi ekugadzira, akadai sepolyvinyl chloride, polyvinylidene chloride, nedzimwe copolymers, suspension polymerization ndiyo inonyanya kushandiswa uye inofanira kunge iri mamonomer asingachinji ehydrophobic akasungirirwa mumvura. Semapolymer anonyungudika mumvura, chigadzirwa cheHydroxypropylMethylCellulose chine basa rakanaka pamusoro uye chinoshanda sema colloidal agents anodzivirira. HydroxypropylMethylCellulose inogona kudzivirira zvinobudirira polymeric particles kuti isaburitse uye isangane. Uyezve, kunyangwe HydroxypropylMethylCellulose iri polymer inonyungudika mumvura, inogona kunyungudika zvishoma mu hydrophobic monomers uye inogona kuwedzera monomer porosity yekugadzira polymeric particles.
Pamusoro pezvo, zvidzidzo zvakaratidza kuti mukugadzirwa kwePVC, mabhizinesi akasiyana anoshandisa nzira dzakasiyana dzekuparadzira, saka hunhu hwekunze hwePVC hunogadzirwa hwakasiyanawo, saka HydroxypropylMethylCellulose inogona kukanganisa mashandiro ePVC resin. Musystem yekuparadzira composite, suspension PVC resin yakagadzirwa kubva kucomposite dispersing agent yepolyvinyl alcohol (PVA) ine madhigirii akasiyana ealcohol uye polymerization uye hydroxypropyl methyl cellulose (HPMC) inogona kuva nemigumisiro yakasiyana pakushanda kwekugadzirisa. Miedzo yakaratidza kuti compound yeHydroxypropylMethylCellulose neKP-08/KZ-04 ine alcoholization degree ye68% -75% iri nani uye inobatsirawo pakupinza resin uye kunyudzwa kweplasticizers.
