I-HPMC (Hydroxypropyl Methyl Cellulose) kanye ne-HEMC (Hydroxy Ethyl Methyl Cellulose) ama-cellulose ether asetshenziswa kakhulu ezintweni zokwakha ngenxa yezakhiwo zawo ezihlukile. Zingama-polymers ancibilika emanzini atholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. I-HPMC ne-HEMC zisetshenziswa njengezithasiselo emikhiqizweni eyahlukene yokwakha ukuze kuthuthukiswe izakhiwo zazo futhi kuthuthukiswe ukusetshenzwa.
Okulandelayo ezinye izicelo ze-HPMC kanye ne-HEMC ezintweni zokwakha:
Izinamathiselo Zethayela: I-HPMC ne-HEMC kuvame ukungezwa kuma-adhesives wethayela ukuze kuthuthukiswe ukusebenza kanye namandla ebhondi. Lawa ma-polymers asebenza njengama-thieners, anikeze isikhathi esingcono sokuvula (i-adhesive ihlala isikhathi esingakanani isetshenziswa) futhi inciphisa ukuwohloka kwamathayili. Baphinde bathuthukise ukunamathela kwe-adhesive kuma-substrates ahlukene.
Izithombo ezinosimende: I-HPMC ne-HEMC zisetshenziswa odakeni lukasimende olufana nokhonkolo, ukhonkolo kanye nezinhlelo zokuqeda ukufakwa kwangaphandle (EIFS). Lawa ma-polymers athuthukisa ukusebenza kodaka, okwenza kube lula ukusabalalisa nokusebenzisa. Zibuye zithuthukise ukubumbana, zinciphise ukumuncwa kwamanzi futhi zithuthukise ukunamathela kodaka kuma-substrates ahlukahlukene.
Imikhiqizo esekwe ku-Gypsum: I-HPMC ne-HEMC isetshenziswa ezintweni ezisekelwe ku-gypsum ezifana namaplasta e-gypsum, izinhlanganisela ezihlangene kanye nezingubo zangaphansi ezizilinganisa ngokwazo. Asebenza njengama-ejenti okugcina amanzi, athuthukisa ukusebenza futhi andise isikhathi sokusetha sento. Lawa ma-polymers athuthukisa ukumelana nokuqhekeka, anciphise ukushwabana futhi athuthukise ukunamathela.
Izinhlanganisela zokuzilinganisa: I-HPMC ne-HEMC zengezwa kumakhompiyutha azilinganisa wona ukuze kuthuthukiswe ukugeleza nokukalanisa izakhiwo. Lawa ma-polymers asiza ukunciphisa i-viscosity, ukulawula ukumuncwa kwamanzi futhi anikeze isiphetho esingcono sendawo. Baphinde bathuthukise ukunamathela kwe-compound ku-substrate.
I-Grouting: I-HPMC kanye ne-HEMC ingasetshenziselwa ukuhlanganisa ama-tile nama-masonry. Basebenza njengama-rheology modifiers, bathuthukisa ukugeleza nokusebenza kwama-grouts. Lawa ma-polymers anciphisa nokungena kwamanzi, athuthukise ukunamathela futhi athuthukise ukumelana nokuqhekeka.
Sekukonke, i-HPMC ne-HEMC zisetshenziswa kakhulu ezintweni zokwakha ngenxa yekhono lazo lokuthuthukisa ukucutshungulwa, ukunamathela, ukugcinwa kwamanzi, kanye nokusebenza kwayo yonke imikhiqizo. Bakhuthaza izinqubo zokwakha ezingcono ngokuthuthukisa ukuqina kanye nekhwalithi yezinto ezihlukahlukene zokwakha.
