I-Hydroxypropylmethylcellulose (HPMC) iyinhlanganisela esetshenziswa kabanzi embonini yokwakha. Umsebenzi wayo oyinhloko ukuthuthukisa izakhiwo zokusebenza kwezinto ezifana nodaka kanye nokhonkolo. Enye yezindlela zokusebenzisa i-HPMC ukuzilinganisa nge-gypsum, okuye kwaba nomthelela omkhulu embonini yokwakha.
I-plaster yokuzilinganisa iyinto esezingeni eliphezulu futhi kulula ukuyifaka futhi ingasetshenziswa phezu kwekhonkrithi noma phansi endala. Iyindlela ethandwayo yokwakha izakhiwo zebhizinisi nezindawo zokuhlala ngenxa yokusebenza kwayo okuphezulu nokuqina kwayo. Inselele enkulu ekusetshenzisweni kwe-plaster yokuzilinganisa ukugcina ikhwalithi nokuvumelana kwezinto ngesikhathi sokulungiselela nokufaka. Yilapho i-HPMC iqala khona ukusebenza.
I-Hydroxypropyl methylcellulose iyisithako esiqina esenziwe ngokwenziwa esifakwa ezingxubeni ezizilinganisayo ezisekelwe ku-gypsum ukuqinisekisa ukusatshalaliswa okulinganayo kwengxube. Iphinde isize ukulawula i-viscosity nokugcina ikhwalithi yezinto zokwakha. I-HPMC iyisithako esibalulekile ekuhlanganiseni kwe-gypsum okuzilinganisayo njengoba iqinisa ingxube, iqinisekisa ukuthi ukuhlukaniswa akwenzeki futhi ithuthukisa amandla okubopha kwengxube.
Inqubo yokufaka i-gypsum yokuzilinganisa ihilela ukuxuba i-gypsum ne-HPMC namanzi. Amanzi asebenza njengomthwali we-HPMC, eqinisekisa ukusatshalaliswa kwawo ngokulinganayo engxubeni. I-HPMC yengezwa engxubeni ngesilinganiso esingu-1-5% sesisindo esomile se-gypsum, kuye ngokuhambisana okufunwayo kanye nokusetshenziswa kokugcina kwezinto.
Kunezinzuzo eziningana zokwengeza i-HPMC engxubeni yeplasta ezilinganisayo. Yandisa ukuqina kwezinto ngokwandisa amandla azo kanye nokumelana namanzi, amakhemikhali kanye nokuguguleka. Ngaphezu kwalokho, i-HPMC yandisa ukuguquguquka kwezinto, okuvumela ukuthi zivumelane nezinguquko zokushisa kanye nomswakama. Lokhu kuvimbela imifantu, kunciphisa imfucuza futhi kuthuthukisa ubuhle bephansi lakho.
I-hydroxypropyl methylcellulose ingasebenza futhi njengomgqugquzeli wokunamathela ngokwandisa amandla esibopho se-gypsum ezilinganisayo ku-substrate. Uma ingxube isetshenziswa, i-HPMC iqinisekisa ukuthi ingxube inamathela ku-substrate, yakha isibopho esihlala njalo nesiqinile. Lokhu kuqeda isidingo sezinamathiselo zemishini, konga isikhathi nemali ngesikhathi sokufakwa.
Enye inzuzo ye-HPMC ekuzilinganiseni okusekelwe ku-gypsum ngumnikelo wayo ekusimeni kwemvelo embonini yokwakha. I-HPMC inobungani nemvelo futhi kulula ukuyilahla, okwenza ibe yindlela ephephile neqhubekayo esikhundleni sezinye izinhlanganisela zamakhemikhali.
I-Hydroxypropyl methylcellulose (HPMC) ibonakale iyisithako esibalulekile ekusetshenzisweni kwe-gypsum-based self-leveling. Ngokufaka isandla ekuhambisaneni, ikhwalithi kanye nokufana kwengxube, i-HPMC ithuthukisa ukuqina kanye nobuhle bezinto ezibonakalayo. Izinzuzo zayo zokuqina kwesibopho sezinto ezibonakalayo zisiza ukonga isikhathi nemali embonini. Ngaphezu kwalokho, ukusetshenziswa kwe-HPMC kukhuthaza ukuzinza kwemvelo, okwenza kube ukukhetha okuthandwayo embonini yokwakha.
