I-Cellulose, eyaziwa nangokuthi i-hydroxypropylmethylcellulose (HPMC), iyisici esibalulekile se-gypsum. I-Gypsum iyinto yokwakha odongeni nophahla esetshenziswa kabanzi. Ihlinzeka ngendawo ebushelelezi, elinganayo elungele ukupenda noma ukuhlobisa. I-Cellulose iyisengezo esingenabo ubuthi, esinobungani nemvelo futhi esingenangozi esisetshenziselwa ukwenza i-gypsum.
I-cellulose isetshenziswa ekwenziweni kwe-gypsum ukuthuthukisa izakhiwo ze-gypsum. Isebenza njengesinamathelisi, ibamba i-plaster ndawonye futhi iyivimbele ukuthi ingaqhekeki noma inciphe njengoba yomile. Ngokusebenzisa i-cellulose engxubeni ye-stucco, ungandisa amandla nokuqina kwe-stucco, okwenza ihlale isikhathi eside futhi idinga ukunakekelwa okuncane.
I-HPMC iyi-polymer yemvelo etholakala ku-cellulose, equkethe amaketanga amade e-glucose, aguqulwa yi-reaction ne-propylene oxide kanye ne-methyl chloride. Le nto iyabola futhi ayinabo ubuthi, iyinto enobungani nemvelo. Ngaphandle kwalokho, i-HPMC iyancibilika emanzini, okusho ukuthi ingaxutshwa kalula nengxube ye-gypsum lapho uyilungisa.
Ukwengeza i-cellulose engxubeni ye-stucco nakho kusiza ekuthuthukiseni izakhiwo zokubopha ze-stucco. Ama-molecule e-cellulose anesibopho sokwakha isibopho phakathi kwe-stucco kanye nobuso obungaphansi. Lokhu kuvumela i-plaster ukuthi inamathele kangcono ebusweni futhi kuyivimbele ekuhlukaneni noma ekuqhekekeni.
Enye inzuzo yokwengeza i-cellulose engxubeni ye-gypsum ukuthi kusiza ukuthuthukisa ukusebenza kahle kwe-gypsum. Ama-molecule e-cellulose asebenza njenge-lubricant, okwenza kube lula ukuthi i-plaster isakazeke. Lokhu kwenza kube lula ukufaka i-plaster odongeni noma ophahleni, okwenza kube bushelelezi.
I-cellulose ingathuthukisa nokubukeka okuphelele kokuqedwa kwe-plaster. Ngokwandisa amandla nokusebenza kahle kwe-stucco, kusiza ukuqinisekisa ukuthi ukuqedwa okubushelelezi, okulinganayo okungenamifantu kanye nokungapheleli kobuso. Lokhu kwenza i-plaster ikhange kakhulu futhi kube lula ukuyipenda noma ukuyihlobisa.
Ngaphezu kwezinzuzo ezibalwe ngenhla, i-cellulose nayo inegalelo ekumelaneni nomlilo kwe-stucco. Uma ingezwa engxubeni ye-gypsum, ingasiza ekunciphiseni ukusabalala komlilo ngokudala umgoqo phakathi komlilo nodonga noma uphahla.
Ukusebenzisa i-cellulose ekukhiqizeni i-gypsum nakho kunezinzuzo eziningana zemvelo. Le nto iyabola futhi ayinaboli, ayinangozi emvelweni nasempilweni yabantu. Ngaphezu kwalokho, njengoba i-cellulose yandisa amandla nokuqina kwe-plaster, iyasiza ekunciphiseni inani lokugcinwa okudingekayo ngokuhamba kwesikhathi. Lokhu kunciphisa inani lemfucuza ekhiqizwayo futhi kusiza ukonga izinsiza.
I-Cellulose iyisici esibalulekile se-gypsum. Ukuyifaka engxubeni ye-stucco kusiza ukuthuthukisa amandla, ukuqina, ukusebenza kahle kanye nokubukeka kwe-stucco. Ngaphezu kwalokho, inikeza izinzuzo eziningana zemvelo ezisiza ekunciphiseni isidingo sokugcinwa isikhathi eside. Ukusebenzisa i-cellulose ku-gypsum kuyisinyathelo esibalulekile ekudaleni izinto zokwakha ezisimeme nezinobungani nemvelo.
