Polyvinyl chloride (PVC)

Mu guhagarika amahwa ya chloride ya vinyl, sisitemu yatatanye yatatanye ifite ingaruka zitaziguye kubicuruzwa, PVC rein, no kurwego rwo gutunganya no kubicuruzwa. HydroxyPropyl Methylcellellse ifasha kunoza ubushyuhe bwo gusimbuka no kugenzura ikwirakwizwa rya PVC), hamwe namafaranga ya 0.025% -0.03% yumusaruro wa PVC. PVC isiga ikozwe muri hydroxyproppoppopyl methylcellse ntabwo ishobora kwemeza imitungo mpuzamahanga gusa, ariko nayo ishobora kugira imitungo myiza yumubiri, imitungo myiza igaragara hamwe nimyitwarire myiza yo gushonga.

PVC ni ibintu birambye kandi birebire birashobora gukoreshwa muburyo butandukanye, haba gukomera cyangwa guhinduka, byera cyangwa umukara hamwe namabara atandukanye hagati.

Mu gukora ibikomokaho, nka chloride ya chloride (pvc), polyvinylidene chloride, hamwe na popolymers, guhagarikwa polémesiriation nuburyo bukunze gukoreshwa kandi bigomba kuba monomers desdrophic yahagaritswe mumazi. Nka polymers-gushonga amazi, hydroxypropyl Igicuruzwa cya methylcellse gifite ibikorwa byiza byo hejuru hamwe nimikorere nkumutekano wa colloivel. HydroxyPropyl Methylcellse irashobora gukumira neza ibice byo gutanga no guterana. Byongeye kandi, nubwo hydroxypropyl methylcellse ni polymer yoroheje muri monomer ya hydrophobic kandi irashobora kongera ubupfumu bwa hydrophomic kugirango umusaruro wubwisanzure bwo gukora ibice bya polymeric.

Ibicuruzwa bya HPMC birashobora gutera imbere mubintu bikurikira muri PVC:

· Ikunze gukoreshwa abakozi bahagaritse.

· Igenzura ingano yinshi no kugabura kwabo

· Ingaruka

· Isobanura uburemere buke bwa PVC.
