Hydroxypropyl Methyl Cellulose yibicuruzwa bifite ibicuruzwa byinshi murwego rwo guhagarika polymerisation ya vinyl chloride mubushinwa.Muguhagarika polymerisation ya vinyl chloride, sisitemu yatatanye igira ingaruka itaziguye kubicuruzwa, PVC resin, no kumiterere yabyo nibicuruzwa.HydroxypropylMethylCellulose ifasha kuzamura ubushyuhe bwumuriro wa resin no kugenzura ingano yikwirakwizwa.PVC resin ikozwe muri hydroxypropylMethylCellulose ntishobora gusa gukora umurongo wimikorere hamwe nubuziranenge mpuzamahanga, ariko kandi irashobora kugira imiterere igaragara yumubiri, ibintu byiza cyane hamwe nimyitwarire myiza ya rheologiya.
Mu gukora ibisigazwa byubukorikori, nka polyvinyl chloride, chloride polyvinylidene, nizindi copolymers, guhagarika polymerisation nibyo bikoreshwa cyane kandi bigomba kuba monomers hydrophobic monomers ihagarikwa mumazi.Nka polymer zishonga mumazi, HydroxypropylMethylCellulose igicuruzwa gifite ibikorwa byiza byubuso kandi bikora nkibikoresho birinda colloidal.HydroxypropylMethylCellulosecan irinda neza ibice bya polymeric kubyara no guteranya.Byongeye kandi, nubwo HydroxypropylMethylCelluloseis polymer yamazi ashonga, irashobora gushonga gato muri hydrophobique monomers kandi irashobora kongera ububobere bwa monomer kugirango ikore uduce duto twa polymeric.
Byongeye kandi, ubushakashatsi bwerekanye ko mugikorwa cyo gukora PVC, inganda zitandukanye zikoresha sisitemu zitandukanye, bityo imitungo yo hanze ya PVC yakozwe nayo iratandukanye, bityo HydroxypropylMethylCellulose irashobora kugira ingaruka kumikorere ya PVC.Muri sisitemu yo gukwirakwiza ibikoresho, sisitemu yo guhagarika PVC yateguwe kuva murwego rwo gukwirakwiza inzoga za polyvinyl (PVA) zifite impamyabumenyi zitandukanye za alcool na polymerisation hamwe na hydroxypropyl methyl selulose (HPMC) bishobora kugira ingaruka zitandukanye mubikorwa byo gutunganya.Ibizamini byagaragaje ko ikomatanya rya HydroxypropylMethylCellulose na KP-08 / KZ-04 hamwe na dogere ya alcool ya 68% -75% nibyiza kandi binagira akamaro kubwinshi bwa resin no kwinjiza plastike.
