Khoom Nta: Dispersion: Kev ncua kev kawm zoo heev dispersion kev ua tau zoo, los ntawm kev kho qhov nro thiab concentration, cov monomer yuav dispersed rau hauv cov khoom zoo. Suspension: txhim kho resin thermal stability thiab tswj particle loj tis, txhim kho particle puab thiab viscosity tis, txo qhov tshwm sim ntawm fisheye. Adsorbability: txhim kho qhov zoo ntawm cov resin thiab cov khoom ua tiav, kom PVC resin los ua ib qho khoob, txhim khu kev nqus ntawm plasticizer.
PVC polymerization system npaj los ntawm HPMC zoo, ntxiv rau kom ntseeg tau tias qhov kev ua tau zoo raws li cov qauv thoob ntiaj teb, tab sis kuj muaj cov khoom zoo ntawm lub cev, cov khoom zoo heev thiab cov cwj pwm zoo rheological. Nyob rau hauv lub compound dispersant system, polyvinyl cawv (PVA) nrog txawv degrees ntawm alcoholysis thiab polymerization thiab hydroxypropyl methylcellulose (HPMC) compound collocation yog zoo dua, uas yog conducive rau lub porosity ntawm resin, thiab nqus ntawm plasticizer kuj muaj txiaj ntsig.
