I-Cellulose, ekwaziwa ngokuba yi-hydroxypropylmethylcellulose (HPMC), yinxalenye ebalulekileyo ye-gypsum. I-Gypsum sisixhobo sokwakha esisetyenziswa kakhulu eludongeni naseluphahleni. Inika umphezulu ogudileyo, olinganayo olungele ukupeyintwa okanye ukuhonjiswa. I-Cellulose sisongezelelo esingenabungozi, esinobuhlobo nokusingqongileyo nesingenabungozi esisetyenziselwa ukwenza i-gypsum.
I-Cellulose isetyenziswa ekwenziweni kwe-gypsum ukuphucula iipropati ze-gypsum. Isebenza njengesincamathelisi, ibamba i-plaster kunye kwaye ithintele ukuba ingaqhekeki okanye inciphe njengoko yomile. Ngokusebenzisa i-cellulose kumxube we-stucco, unokwandisa amandla kunye nokuqina kwe-stucco, okwenza ihlale ixesha elide kwaye ingafuneki ukulungiswa okuninzi.
I-HPMC yipolymer yendalo ephuma kwi-cellulose, equlathe imixokelelwane emide yeglucose, eguqulwa yi-reaction ene-propylene oxide kunye ne-methyl chloride. Le nto iyabola kwaye ayinabungozi, yinto enobuhlobo nokusingqongileyo. Ngaphandle koko, i-HPMC iyanyibilika emanzini, oko kuthetha ukuba ingaxutywa lula kumxube we-gypsum xa uyilungisa.
Ukongeza i-cellulose kumxube we-stucco kukwanceda ekuphuculeni iipropati zokubopha ze-stucco. Iimolekyuli ze-cellulose zinoxanduva lokwenza unxibelelwano phakathi kwe-stucco kunye nomphezulu ongaphantsi. Oku kuvumela i-plaster ukuba inamathele ngcono kumphezulu kwaye kuyithintele ekuqhekekeni okanye ekuqhekekeni.
Enye inzuzo yokongeza i-cellulose kumxube we-gypsum kukuba inceda ukuphucula ukusebenza kwe-gypsum. Iimolekyuli ze-cellulose zisebenza njenge-lubricant, okwenza kube lula ukuba i-plaster isasazeke. Oku kwenza kube lula ukufaka i-plaster eludongeni okanye eluphahleni, nto leyo enika umphezulu othambileyo.
I-Cellulose inokuphucula ukubonakala kwayo yonke i-plaster finishes. Ngokwandisa amandla kunye nokusebenza kakuhle kwe-stucco, inceda ukuqinisekisa ukuba i-stucco igudileyo, igqibelele ngokulinganayo, ayinazimfanta kunye neziphene ezingaphezulu. Oku kwenza i-plaster ibe nomtsalane ngakumbi kwaye kube lula ukuyipeyinta okanye ukuyihombisa.
Ukongeza kwiingenelo ezidweliswe apha ngasentla, i-cellulose ikwanegalelo ekumelaneni nomlilo kwe-stucco. Xa ifakwa kumxube we-gypsum, inokunceda ekunciphiseni ukusasazeka komlilo ngokwenza umqobo phakathi komlilo nodonga okanye umphezulu wesilingi.
Ukusebenzisa i-cellulose ekwenzeni i-gypsum kukwaneenzuzo ezininzi zokusingqongileyo. Le nto iyabola kwaye ayinabungozi, ayinabungozi kwindalo nakwimpilo yabantu. Ukongeza, ekubeni i-cellulose inyusa amandla kunye nokuqina kwe-plaster, inceda ukunciphisa ukugcinwa okufunekayo ekuhambeni kwexesha. Oku kunciphisa ubungakanani benkunkuma eveliswayo kwaye kunceda ukonga izixhobo.
I-Cellulose yinxalenye ebalulekileyo ye-gypsum. Ukuyifaka kumxube we-stucco kunceda ukuphucula amandla, ukuqina, ukusebenza kakuhle kunye nokubonakala kwe-stucco. Ukongeza, inika iingenelo ezininzi zokusingqongileyo ezinceda ekunciphiseni isidingo sokugcinwa ixesha elide. Ukusebenzisa i-cellulose kwi-gypsum linyathelo elibalulekileyo ekudaleni izixhobo zokwakha ezizinzileyo nezinobuhlobo nokusingqongileyo.
