Ukunamathela: Kwenza ngcono ukunamathela kodaka kanye ne-stucco ezinhlobonhlobo zama-substrates, okuholela ekuqedeni okuqinile, okuhlala isikhathi eside.
3.2 Izinamathiselo zamathayela nama-grouts:
Ukumelana Nokushelela: Kuzinto zokunamathela zamathayili, i-HPMC isiza ukulawula ukumelana nokushelela ukuze kuqinisekiswe ukuthi ithayela linamathela ngokuqinile phezulu.
Ukuqina: Njenge-ejenti ejiyayo, i-HPMC inegalelo ekubambisaneni kahle kwezinamathelisi zamathayili nama-grouts.
Ukugcinwa kwamanzi: Kuvimbela ukuhwamuka kwamanzi ngokushesha futhi kukhuthaze ukuphulukiswa okusebenzayo kwezinamathiselo kanye ne-grout.
3.3 Ukunikezwa okusekelwe kusimende:
I-Crack Resistance: I-HPMC ithuthukisa ukuguquguquka nokumelana nokuqhekeka kokunikezwa okusekelwe kusimende, inikeze ukuqina endaweni eqediwe.
Ukungaguquguquki: Kuyasiza ukugcina ukuvumelana okufiswayo kokunikezwayo ngesikhathi sokwakha, ukuvimbela ukuwohloka nokuqinisekisa ukujiya okufanayo.
3.4 Izinhlanganisela zokuzilinganisa:
Ukugeleza: Phakathi kwezinhlanganisela zokuzilinganisa, i-HPMC ithuthukisa ukugeleza, yenza ukusabalalisa kanye nokubeka izinga kube lula.
Ukugcinwa Kwamanzi: Kuvimbela ukulahlekelwa umswakama ngokushesha, kuqinisekiswe ukuphulukiswa okufanele kanye nokuthuthukiswa kwezakhiwo ezifiselekayo.
3.5 Imikhiqizo yeGypsum:
Ukungaguquguquki: I-HPMC isetshenziswa emikhiqizweni esekwe ku-gypsum ukulawula ukungaguquguquki nokusetha isikhathi.
Ukugcinwa kwamanzi: Kuvimbela ukomiswa ngaphambi kwesikhathi kwengxube ye-plaster futhi kukhuthaze ukugeleza kwamanzi okuphelele.
4. Izinzuzo zokusebenzisa i-HPMC ekwakheni:
Ukucutshungulwa Okuthuthukisiwe: I-HPMC ithuthukisa ukucutshungulwa kwezinto zokwakha, ikwenze kube lula ukuphatha nokusebenzisa.
Ukugcinwa kwamanzi: Izakhiwo zokugcina amanzi ze-HPMC zifaka isandla ekwelapheni okusebenzayo kwezinto zikasimende.
Ukuhlanganisa nokuhlanganisa: Kuthuthukisa izakhiwo zokuhlanganisa nokuhlanganisa zemikhiqizo yokwakha, ngaleyo ndlela kwenze isakhiwo sibe namandla futhi siqine kakhudlwana.
Ukuqina: Njengokuqina, i-HPMC inikeza i-viscosity edingekayo ezintweni ezihlukahlukene zokwakha ukuze kuqinisekiswe ukusetshenziswa okufanele.
Ukumelana nokuqhekeka: Ukwengezwa kwe-HPMC kuthuthukisa ukuguquguquka nokumelana nokuqhekeka kwendawo eqediwe.
Ukusetha Ukulawula Isikhathi: I-HPMC inikeza ukulawula okungcono ngesikhathi sokusetha sezinto ezisekelwe kusimende.
5. Izinselelo nokucatshangelwa:
Ukulawulwa Kwemithamo: Umthamo olungile ubalulekile ukufeza ukusebenza okufunayo futhi ukusetshenziswa ngokweqile kwe-HPMC kungase kubangele imiphumela emibi.
Ukuhambisana: Ukuhambisana nezinye izithasiselo kanye nezinto zokwakha kufanele kubhekwe ukuvimbela noma yikuphi ukusabela okungekuhle.
Umthelela Wezemvelo: Nakuba i-HPMC ngokwayo ibhekwa njengephephile uma kuqhathaniswa, umthelela wemvelo wokukhiqizwa nokulahlwa kwayo kufanele ucatshangelwe.
6. Isiphetho:
Ngamafuphi, i-hydroxypropyl methylcellulose (HPMC) idlala indima ebalulekile embonini yezokwakha, ihlinzeka ngezinzuzo eziningi ezihlukahlukene ekusetshenzisweni okuhlukahlukene.Izakhiwo zayo eziyingqayizivele ezifana nokugcinwa kwamanzi, ukuqina nokunamathela okuthuthukisiwe kwenza kube isengezo esibalulekile ekwakhiweni kodaka, izinamathiselo, ama-plaster nezinye izinto zokwakha.Naphezu kwezinselelo zokulawulwa komthamo nezici zemvelo, umthelela omuhle we-HPMC ekusebenzeni nasekuqineni kwemikhiqizo yokwakha iyenza ibe yingxenye ebalulekile yekhithi yamathuluzi yokwakha yesimanje.Njengoba imboni yezokwakha iqhubeka nokuvela, i-HPMC kungenzeka ihlale ibambe iqhaza ekuthuthukiseni ikhwalithi nokusebenza kahle kwezinto zokwakha nezinqubo.
