I-Cellulose, eyaziwa nangokuthi i-hydroxypropylmethylcellulose (HPMC), iyisakhi esibalulekile se-gypsum. I-Gypsum isetshenziswa kabanzi ngodonga nophahla lwendlu. Ihlinzeka ngobushelelezi, ngisho nendawo elungele ukudweba noma ukuhlobisa. I-Cellulose iyisengezo esingenabuthi, esilungele imvelo futhi esingenabungozi esisetshenziselwa ukwenza i-gypsum.
I-Cellulose isetshenziswa ekwenzeni i-gypsum ukuthuthukisa izakhiwo ze-gypsum. Isebenza njenge-adhesive, ibambe ukhonkolo ndawonye futhi ivimbele ukuthi ingaqhekeki noma inciphe njengoba yoma. Ngokusebenzisa i-cellulose engxube ye-stucco, ungakwazi ukwandisa amandla nokuqina kwe-stucco, okwenza ukuthi ihlale isikhathi eside futhi idinga ukulungiswa okuncane.
I-HPMC iyi-polymer yemvelo etholakala ku-cellulose, ehlanganisa amaketanga amade e-glucose, eguqulwa ngokusabela nge-propylene oxide ne-methyl chloride. Impahla iyabola futhi ayinabo ubuthi, into ehambisana nemvelo. Ngaphandle kwalokho, i-HPMC iyancibilika emanzini, okusho ukuthi ingaxutshwa kalula kumxube we-gypsum uma uyilungiselela.
Ukwengeza i-cellulose engxube ye-stucco nakho kusiza ukuthuthukisa izakhiwo zokubopha ze-stucco. Ama-molecule e-cellulose anesibopho sokwenza isibopho phakathi kwe-stucco nendawo engaphansi. Lokhu kuvumela i-plaster ukuthi ibambelele kangcono phezulu futhi ivimbele ukuthi ingahlukani noma iqhekeke.
Enye inzuzo yokwengeza i-cellulose engxube ye-gypsum ukuthi isiza ukuthuthukisa ukusebenza kwe-gypsum. Amangqamuzana e-cellulose asebenza njenge-lubricant, okwenza kube lula ukuthi udaka lusakazeke. Lokhu kwenza kube lula ukufaka ukhonkolo odongeni noma odongeni, kunikeze indawo ebushelelezi.
I-Cellulose nayo ingathuthukisa ukubukeka okuphelele kokuqedwa kwe-plaster. Ngokwandisa amandla nokusebenza kwe-stucco, isiza ukuqinisekisa ukushelela, ngisho nokuqeda okungenayo imifantu nokungapheleli kwendawo. Lokhu kwenza i-plaster ikhange nakakhulu futhi kube lula ukuyipenda noma ukuyihlobisa.
Ngaphezu kwezinzuzo ezibalwe ngenhla, i-cellulose iphinde ibe nomthelela ekwandeni komlilo we-stucco. Uma yengezwa kumxube we-gypsum, ingasiza ekubambezeleni ukusabalala komlilo ngokudala umgoqo phakathi komlilo nodonga noma indawo yophahla.
Ukusebenzisa i-cellulose ekwenzeni i-gypsum nakho kunezinzuzo eziningana zemvelo. Impahla iyabola futhi ayinabo ubuthi, ayinabungozi emvelweni nempilo yabantu. Ukwengeza, njengoba i-cellulose ikhulisa amandla nokuqina kwe-plaster, isiza ukunciphisa inani lokugcinwa okudingekayo ngokuhamba kwesikhathi. Lokhu kunciphisa inani lemfucuza ekhiqizwa futhi kusiza ukulondoloza izinsiza.
I-Cellulose iyisici esibalulekile se-gypsum. Ukuyengeza engxube ye-stucco kusiza ukuthuthukisa amandla, ukuqina, ukusebenza nokubukeka kwe-stucco. Ngaphezu kwalokho, inikeza izinzuzo ezimbalwa zemvelo ezisiza ukunciphisa isidingo sokunakekelwa kwesikhathi eside. Ukusebenzisa i-cellulose ku-gypsum kuyisinyathelo esibalulekile ekudaleni izinto zokwakha ezisimeme futhi ezinobungani nemvelo.
