IHydroxypropylmethylcellulose (HPMC) iyipolymer eguquguqukayo esetshenziswa kabanzi embonini yezokwakha. Kuyinto engenabuthi, engenaphunga, futhi ezinzile i-pH ehlanganiswe ngokwethula i-hydroxypropyl namaqembu e-methyl ku-cellulose yemvelo. I-HPMC itholakala kumabanga ahlukahlukene anama-viscosity ahlukahlukene, osayizi bezinhlayiyana namadigri okushintsha. Kuyi-polymer encibilika emanzini engakha ama-gel ekugxilweni okuphezulu kodwa ibe nomthelela omncane noma ongenawo nhlobo ku-rheology yamanzi ekugxilweni okuphansi. Lesi sihloko sidingida ukusetshenziswa kwe-HPMC ezintweni zokwakha ezahlukahlukene.
Ukusetshenziswa kwe-HPMC ekuplasteni nasekunikezeni
Ukwakhiwa kwezakhiwo kudinga izakhiwo ezithuthukisiwe ezingaphezulu kwezindonga, phansi kanye nophahla. I-HPMC yengezwa ku-gypsum nezinto zokuplasta ukuze kuthuthukiswe ukusebenza kwazo nokunamathela kwazo. I-HPMC ithuthukisa ukushelela nokuvumelana kwe-plastering kanye nezinto zokuplasta. Yandisa amandla okugcina amanzi wezingxube, okuwavumela ukuthi abambelele kangcono odongeni noma endaweni yaphansi. I-HPMC isiza futhi ukuvimbela ukushwabana nokuqhekeka ngesikhathi sokwelapha nokomisa, okwandisa ukuqina kwento enamathelayo.
Ukusetshenziswa kwe-HPMC ku-adhesive tile
Izinamathiselo zamathayela ziyingxenye ebalulekile yephrojekthi yokwakha yesimanje. I-HPMC isetshenziswa ekunamathelweni kwamathayela ukuthuthukisa ukunamathela kwawo, ukugcinwa kwamanzi nokusebenza kokwakha. Ukwengeza i-HPMC ekwakhekeni kwe-adhesive kukhulisa kakhulu isikhathi esivulekile sokunamathisela, kunikeza abafaki isikhathi esengeziwe sokwenza izinguquko ngaphambi kokuthi ithayela limiswe. I-HPMC futhi inyusa ukuguquguquka nokuqina kwentambo yesibopho, inciphisa ingcuphe yokuncipha noma ukuqhekeka.
Ukusetshenziswa kwe-HPMC kuma-self-leveling compounds
Izinhlanganisela zokuzilinganisa zisetshenziselwa ukulinganisa phansi futhi zenze indawo ebushelelezi, elinganayo ukuze kufakwe izinto zokubeka phansi. I-HPMC yengezwa kumakhompiyutha azilinganisayo ukuze kuthuthukiswe ukugeleza kwawo kanye nezakhiwo zokuleveling. I-HPMC inciphisa i-viscosity yokuqala yengxube, ikwenze kube lula ukuyisebenzisa kanye nokwenza ngcono izinga. I-HPMC iphinde ikhulise ukugcinwa kwamanzi kwengxube, iqinisekisa amandla ebhondi angcono phakathi kwezinto eziphansi kanye ne-substrate.
Ukusetshenziswa kwe-HPMC ku-caulk
I-Grout isetshenziselwa ukugcwalisa izikhala phakathi kwamathayili, itshe lemvelo noma ezinye izinto zokubeka phansi. I-HPMC yengezwe kwinhlanganisela ehlanganyelwe ukuthuthukisa ukusebenza kwayo nokuqina. I-HPMC inyusa i-viscosity yengxube, ikwenze kube lula ukusabalalisa nokunciphisa ukushwabana nokuqhekeka kwezinto zokugcwalisa ngesikhathi sokwelashwa. I-HPMC iphinde ithuthukise ukunamathela kwesigcwalisi ku-substrate, inciphisa amathuba okuba nezikhala nokuqhekeka kwesikhathi esizayo.
I-HPMC emikhiqizweni esekwe ku-gypsum
Imikhiqizo esekelwe ku-Gypsum, efana ne-plasterboard, amathayela osilingi namabhodi okufakelwa, isetshenziswa kakhulu embonini yokwakha. I-HPMC isetshenziswa emikhiqizweni esekwe ku-gypsum ukuthuthukisa ukusebenza kwayo, ukubeka isikhathi namandla. I-HPMC inciphisa isidingo samanzi sokubunjwa, ivumela okuqukethwe okuqinile okuphezulu, okwandisa amandla nokuqina komkhiqizo oqediwe. I-HPMC iphinde ithuthukise ukunamathela phakathi kwezinhlayiya ze-gypsum kanye ne-substrate, iqinisekisa isibopho esihle.
Ekuphetheni
IHydroxypropylmethylcellulose (HPMC) iyi-polymer eguquguqukayo esetshenziswa ezinhlobonhlobo zezinto zokwakha. I-HPMC ithuthukisa ukusebenza kwe-gypsum nezinto zokuplasta, izinto zokunamathisela zamathayela, izinhlanganisela ezizilinganisa, ama-grouts kanye nemikhiqizo esekwe ku-gypsum. Ukusebenzisa i-HPMC kulezi zinto kuthuthukisa ukucutshungulwa, ukunamathela, ukugcinwa kwamanzi nokuqina. Ngakho-ke, i-HPMC isiza ukwakha izinto zokwakha ezinamandla, ezihlala isikhathi eside, ezihlala isikhathi eside ezihlangabezana nezidingo eziphezulu zezakhiwo zesimanje.
