IHydroxypropylmethylcellulose (HPMC) iyinhlanganisela esetshenziswa kabanzi embonini yezokwakha. Umsebenzi wawo oyinhloko ukuthuthukisa izakhiwo zokusebenza zezinto ezifana nodaka nokhonkolo. Esinye sezicelo ze-HPMC ukuzilinganisa kwe-gypsum, okube nomthelela omkhulu embonini yezokwakha.
Ukhonkolo ozilinganisa uyisisetshenziswa sezinga eliphezulu esifakwa kalula futhi singafakwa phezu kukakhonkolo noma phansi okudala. Kuyisinqumo esidumile sokwakhiwa kwezohwebo nezindawo zokuhlala ngenxa yokusebenza kwayo okuphezulu nokuqina. Inselele enkulu ekufakweni kukakhonkolo okwazi ukuzilinganisa ukugcina ikhwalithi nokuvumelana kwezinto ngesikhathi sokulungiselela nokufakwa. Yilapho i-HPMC iqala khona ukudlala.
I-Hydroxypropyl methylcellulose iwugqinsi wokwenziwa owengezwa kumamiksi okuzilinganisa asuselwa ku-gypsum ukuze kuqinisekiswe ngokulinganayo ukusatshalaliswa kwengxube. Kuyasiza futhi ukulawula i-viscosity nokugcina ikhwalithi yezinto. I-HPMC iyisithako esibalulekile kuzingxube zegypsum ezizilinganisa njengoba iqinisa ingxube, iqinisekisa ukuthi ukuhlukaniswa akwenzeki futhi kuthuthukisa amandla okubopha wengxube.
Inqubo yokufaka isicelo se-gypsum yokuzilinganisa ihlanganisa ukuxuba i-gypsum ne-HPMC namanzi. Amanzi asebenza njengesiphathi se-HPMC, eqinisekisa ukusatshalaliswa kwawo ngokulinganayo kungxube. I-HPMC yengezwa ekuxubeni ngesilinganiso esingu-1-5% wesisindo esomile se-gypsum, kuye ngokuvumelana okufunayo kanye nokuphela kokusetshenziswa kwezinto.
Kunezinzuzo ezimbalwa zokwengeza i-HPMC kumxube we-plaster ozilinganisa wona. Ikhulisa ukuqina kwento ngokwandisa amandla ayo kanye nokumelana namanzi, amakhemikhali kanye nokuhuzuka. Ngaphezu kwalokho, i-HPMC inyusa ukuguquguquka kwezinto, ivumela ukuthi ivumelane nezinguquko kuzinga lokushisa kanye nomswakama. Lokhu kuvimbela imifantu, kunciphisa imfucuza futhi kuthuthukise ubuhle be-flooring yakho.
IHydroxypropyl methylcellulose ingasebenza futhi njengomgqugquzeli wokunamathela ngokwandisa amandla ebhondi egypsum ezilinganisa ku-substrate. Uma ingxube isetshenziswa, i-HPMC iqinisekisa ukuthi ingxube inamathela ku-substrate, yakha isibopho esihlala njalo nesiqinile. Lokhu kuqeda isidingo sezibophelelo zemishini, ukonga isikhathi nemali ngesikhathi sokufakwa.
Enye inzuzo ye-HPMC ekuzilinganiseleni kwe-gypsum ngumnikelo wayo ekusimameni kwemvelo embonini yezokwakha. I-HPMC inobungani bemvelo futhi kulula ukuyilahla, okuyenza ibe enye indlela ephephile neqhubekayo kwezinye izinhlanganisela zamakhemikhali.
I-Hydroxypropyl methylcellulose (HPMC) ifakazele ukuthi iyisithako esibalulekile ekusetshenzisweni kokuzilinganisa okusekelwe ku-gypsum. Ngokufaka isandla ekuvumelaneni, ikhwalithi kanye nokufana kwengxube, i-HPMC ithuthukisa ukuqina nobuhle bezinto ezibonakalayo. Izinzuzo zayo zamandla ebhondi yezinto ezibonakalayo ezithuthukisiwe zisiza ukonga isikhathi nemali yomkhakha. Ukwengeza, ukusetshenziswa kwe-HPMC kukhuthaza ukusimama kwemvelo, okwenza kube ukukhetha okuthandwayo embonini yezokwakha.
