I-Hydroxypropylmethylcellellellose (HPMC) iyingxenye esetshenziswa kabanzi embonini yezokwakha. Umsebenzi wayo oyinhloko ukuthuthukisa izakhiwo ezisebenzayo zezinto ezifana nodaka nokhonkolo. Enye yezinhlelo zokusebenza ze-HPMC yi-gypsum-based ukuzimela, okuye kwaba nomthelela omkhulu embonini yezokwakha.
Upulati we-Self-Leages iyinto esezingeni eliphakeme yophansi okulula ukuyifaka futhi ingasetshenziswa ngaphezulu kokhonkolo noma ezinyaweni ezindala. Kuyindlela ethandwayo yokwakhiwa kwezentengiso kanye nokuhlala ngenxa yokusebenza kwayo okuphezulu nokuqina. Inselelo enkulu kuhlelo lokusebenza lwe-self-leselsing spicaster lugcina ikhwalithi nokuvumelana kokuqukethwe kwezinto zokulungiselela nokufakwa. Yilapho i-HPMC ingena khona.
I-Hydroxypropyl Methylcellulose ingumuntu ohlukaniswayo ongezwe ukuxubeka okusetshenziswa ngokuzikhandla kwe-gypsum ukuqinisekisa ngisho nokusatshalaliswa kokuhlanganiswa. Kuyasiza nokulawula ukubonakala nokugcina ikhwalithi yalokho okuqukethwe. I-HPMC isithako esibalulekile ekuzihlanganisweni kwe-gypsum okuzenzakalelayo njengoba iqinisa le ngxube, ukuqinisekisa ukuthi ukuhlukaniswa akwenzeki futhi kuthuthukise amandla okubopha kwengxube.
Inqubo yokufaka isicelo se-gypsum yokuzilinganisa ifaka ukuxuba i-gypsum nge-HPMC namanzi. Amanzi asebenza njengesiphathi se-HPMC, eqinisekisa ukusatshalaliswa kwayo engxube. I-HPMC yengezwa ku-xuchathini ngesilinganiso se-1-5% yesisindo esomile se-gypsum, kuya ngokuvumelana okufiselekayo nokusetshenziswa kokuphela kokuqukethwe.
Kunezinzuzo eziningana zokwengeza i-HPMC kwi-Plaster Plaster Dix. Kwandisa ukuqina kokuqina ngokwengeziwe ngokwandisa amandla alo nokumelana namanzi, amakhemikhali kanye ne-abrasion. Ngaphezu kwalokho, i-HPMC inyusa ukuguquguquka kwezinto ezibonakalayo, ukuvumela ukuthi ivumelane nezinguquko ekushiseni nasemaphethelweni. Lokhu kuvimbela imifantu, kunciphisa imfucuza futhi kuthuthukise ama-aesthetics amabala akho.
I-Hydroxypropylm methylcellulose nayo ingasebenza njengomgqugquzeli wokunamathela ngokwandisa amandla ebhondi we-gypsum ozilinganise ukuya engxenyeni engezansi. Lapho ingxube isetshenziswa, i-HPMC iqinisekisa ukuthi ingxube inamathela ku-substrate, yakha isibopho saphakade nesinamandla. Lokhu kuqeda isidingo se-fasteners emishini, ukonga isikhathi nemali ngesikhathi sokufakwa.
Enye inzuzo ye-HPMC e-Gypsum-based ukuzilolonga kungumnikelo wayo ekusimeni kwezemvelo embonini yezokwakha. I-HPMC inobungani bemvelo futhi kulula ukuyilahla, okwenza kube ngenye indlela ephephile futhi eqhubekayo kwamanye amakhemikhali.
I-Hydroxypropylm methylcellulose (HPMC) ifakazele ukuthi iyingxenye ebalulekile kwi-gypsum-based ukuzimela kokuzimela. Ngokufaka isandla ekuguquguqukeni, ikhwalithi kanye nokufana kwengxube, i-HPMC ithuthukisa ukuqina kanye nama-aesthetics okuqukethwe. Izinzuzo zalo zokuqina kwamandla ezinto ezibonakalayo kusiza ukusindisa isikhathi nemali yemboni. Ngokwengeziwe, ukusetshenziswa kwe-HPMC kukhuthaza ukusimama kwemvelo, okwenza kube ukukhetha okuthandwayo embonini yezokwakha.
