Iyiphi indima ye-latex powder ehlakazeka kabusha odakeni olususelwa ku-gypsum?

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.

Ngamafuphi, i-cellulose iyingxenye ebalulekile ye-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.
