Ukumiswa kwe-polymerization ye-hydroxypropyllylylykl methylcellulose ku-PVC

Ukumiswa kwe-polymerization ye-hydroxypropyllylyll methylcellulose (HPMC) ePolyvinyl Chloride (PVC) akuyona inqubo evamile. I-HPMC isetshenziswa ngokuyinhloko njengesengezo noma i-modifier kuzakhi ze-PVC kunokuba njenge-ejenti ye-polymerization.

Kodwa-ke, i-HPMC ingangeniswa ekwakhiweni kwe-PVC ngezinqubo ezihlanganisiwe lapho ihlanganiswa khona ne-PVC resin nezinye izithasiselo zokuthola izakhiwo ezithile noma izithuthukisi zokusebenza. Ezimweni ezinjalo, i-HPMC isebenza imisebenzi ehlukahlukene efana nesikhulu, i-Binder, Stabilizer, noma i-Rheology modifier.

Nazi ezinye izindima ezijwayelekile ze-HPMC ngokwakhiwa kwe-PVC:

1. I-Shidener kanye ne-Rheology Modifier: I-HPMC ingangezwa ekunikezelweni kwe-PVC ukulungisa i-viscosity, yenza ngcono ukucubungula izici, futhi ithuthukise izindawo zokugeleza ze-polymer lincibilike ngesikhathi sokulungiswa.
2. I-Binder Prompoter: I-HPMC ithuthukisa ukunamathela phakathi kwezinhlayiya ze-PVC nezinye izithasiselo ekwakhekeni, ukukhuthaza i-homogeneity nokuqina. Kuyasiza ukubopha izithako ndawonye, ​​ukunciphisa ukuhlukaniswa kanye nokwenza ngcono ukusebenza okuphelele kwamakhompiyutha e-PVC.
3. I-Stabilizer kanye nokwenziwa kwepulasitiki: I-HPMC isebenza njenge-Stabilizer ekusungulweni kwe-PVC, ukuhlinzeka ukumelana nokuwohloka okushisayo, imisebe ye-UV, kanye ne-oxidation. Iphinde ithuthukise ukuhambisana kwamapulasitiki nge-PVC resin, ukuthuthukisa ukuguquguquka, ukuqina nokuqina kwemikhiqizo ye-PVC.
4. I-Impactic modifier: Kuzinhlelo ezithile ze-PVC, i-HPMC ingasebenza njengesiguquli somthelela, ukuthuthukisa ubulukhuni kanye nokumelana nomthelela wemikhiqizo ye-PVC. Kuyasiza ukukhulisa i-couctility kanye nokuqina kobunzima bezinhlanganisela ze-PVC, kunciphisa amathuba okuhluleka kwe-brittle.
5. I-Filler ne-ejenti yokuqinisa: I-HPMC ingasetshenziswa njenge-filler noma i-ejenti yokuqinisa e-ejenti ye-PVC ukukhulisa izakhiwo zemishini ezifana namandla ashubile, amamodula. Kuthuthukisa ukusebenza okuphelele kanye nobuqotho bemikhiqizo ye-PVC.

Ngenkathi i-HPMC ingafani ne-polymerized nge-PVC ngokumiswa kwe-polymerization, kuvame ukwethulwa kuzakhiwo ze-PVC ngezinqubo ezihlanganisiwe ukufezekisa izithuthukisi zokusebenza ezithile. Njengesengezo noma i-modifier, i-HPMC inikela ngezakhiwo ezahlukahlukene zemikhiqizo ye-PVC, ibenze balungele izinhlelo eziningi zezicelo ezimbonini ezinjengezokwakha, izimoto, ukupakipha, kanye nokunakekelwa kwezempilo.
