I-HPMC (Hydroxypropyl Methyl Cellulose) kanye ne-HEMC (Hydroxy Ethyl Methyl Cellulose) yi-cellulose ethers ezivame ukusetshenziswa ezintweni zokwakha ngenxa yezakhiwo zazo ezihlukile. Ziyi-polymers ezincibilika emanzini ezitholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. I-HPMC kanye ne-HEMC zisetshenziswa njengezithasiselo emikhiqizweni eyahlukahlukene yokwakha ukuthuthukisa izakhiwo zazo nokuthuthukisa ukucutshungulwa kwazo.
Okulandelayo ezinye zezindlela zokusebenzisa i-HPMC ne-HEMC ezintweni zokwakha:
Izinamathiseli Zamathayela: I-HPMC ne-HEMC zivame ukungezwa kuzinamathiseli zamathayela ukuze kuthuthukiswe ukusebenza kahle kanye namandla okubopha. Lawa ma-polymer asebenza njengeziqinisi, ahlinzeka ngesikhathi esingcono sokuvula (isikhathi esingakanani i-adhesive ehlala isetshenziswa) futhi anciphisa ukugoba kwethayela. Aphinde athuthukise ukunamathela kwe-adhesive kuma-substrate ahlukene.
Ama-Cementitious Mortars: I-HPMC ne-HEMC zisetshenziswa kuma-cementitious mortars afana nama-plaster, ama-plaster kanye nezinhlelo zokuqeda ukufudumeza kwangaphandle (i-EIFS). Lawa ma-polymers athuthukisa ukusebenza kahle kwe-mortar, okwenza kube lula ukusabalalisa nokusebenzisa. Aphinde athuthukise ukuhlangana, anciphise ukumuncwa kwamanzi futhi athuthukise ukunamathela kwama-mortar ezindaweni ezahlukene.
Imikhiqizo esekelwe ku-gypsum: I-HPMC kanye ne-HEMC zisetshenziswa ezintweni ezisekelwe ku-gypsum ezifana nama-plaster e-gypsum, ama-joint compounds kanye ne-self-leveling underlayments. Zisebenza njengezinto zokugcina amanzi, zithuthukisa ukusebenza kahle futhi zandise isikhathi sokusetha kwezinto. Lawa ma-polymer athuthukisa nokumelana nokuqhekeka, anciphise ukushwabana futhi athuthukise ukunamathela.
Ama-Compounds Azilinganisayo: I-HPMC kanye ne-HEMC zengezwa kuma-compounds azilinganisayo ukuze kuthuthukiswe ukugeleza kanye nezakhiwo zokulinganisa. Lawa ma-polymer asiza ekunciphiseni i-viscosity, alawule ukumuncwa kwamanzi futhi anikeze ukuqedwa okungcono kobuso. Aphinde athuthukise ukunamathela kwe-compound ku-substrate.
Ukuhlanganisa: I-HPMC ne-HEMC zingasetshenziswa ekuhlanganiseni ama-tile kanye nokwakha. Zisebenza njengeziguquli ze-rheology, zithuthukisa ukugeleza nokusebenza kahle kwama-grout. Lawa ma-polymer anciphisa ukungena kwamanzi, athuthukise ukunamathela futhi athuthukise ukumelana nokuqhekeka.
Sekukonke, i-HPMC kanye ne-HEMC zisetshenziswa kabanzi ezintweni zokwakha ngenxa yekhono lazo lokuthuthukisa ukucutshungulwa, ukunamathela, ukugcinwa kwamanzi, kanye nokusebenza kahle kwemikhiqizo. Zikhuthaza imikhuba yokwakha engcono ngokuthuthukisa ukuqina kanye nekhwalithi yezinto ezahlukahlukene zokwakha.
