I-Polyvinyl Chloride (PVC)

E-polymerization ye-polymerization ye-vinyl chloride, uhlelo oluhlakazekile lunomthelela oqondile kumkhiqizo, i-PVC resin, kanye nekhwalithi yokusebenza kwayo nemikhiqizo. I-Hydroxypropyllylylylylyly isiza ukuthuthukisa ukuqina okushisayo kwe-resin nokulawula ukusatshalaliswa kosayizi wezinhlayiyana (ngamanye amagama, nama-akhawunti awo angu-0.025% -0.03% wokukhiqizwa kwe-PVC. I-PVC resin eyenziwe ngekhwalithi ephezulu ye-hydroxypropylll methylcellulose hhayi nje kuphela ukuqinisekisa umugqa wokusebenza namazinga omhlaba, kepha futhi angaba nezindawo ezinhle ezibonakalayo ezibonakalayo, izindlela ezinhle kakhulu zezinhlayiyana ezihle kakhulu.

I-PVC iyinto ehlala isikhathi eside futhi ende ehlala njalo engasetshenziswa ezinhlelweni ezahlukahlukene, kungaba eziqinile noma eziguquguqukayo, ezimhlophe noma ezimnyama nemibala ehlukahlukene phakathi.

Ekwenziweni kwama-resins zokwenziwa, njenge-polyvinyl chloride (PVC), i-polyvinylidene chloride, namanye ama-polymermers, ama-polymerization asetshenziswa kakhulu futhi kufanele abe ngamamomothi angenama-hydrophobic ama-hydrophobic amiswe emanzini. Njengama-polymers ancibilikayo, i-hydroxypropyllylylylylylyl methylcellulose umkhiqizo unemisebenzi emihle kakhulu nemisebenzi njengabavikeli be-colloidal. I-Hydroxypropyl Methylcellulose ingavimbela ngempumelelo izinhlayiya ze-polymeric ekukhiqizeni nasekuqoqweni kwe-agglomeration. Ngaphezu kwalokho, yize i-hydroxypropyllylylyly methylcellose iyi-polymer engenamanzi, ingahle incibilike amamomothi we-hydrophobic futhi ingakhulisa i-monomer poriation yokukhiqizwa kwezinhlayiya ze-polymeric.

Imikhiqizo ye-CHIN HPMC ingathuthuka yizakhiwo ezilandelayo ku-PVC:

· I-ejenti evame ukusetshenziswa kakhulu.

· Ilawula usayizi wezinhlayiyana nokusatshalaliswa kwawo

Ithonya i-porolity

· Kuchaza isisindo se-PVC.
