Yiziphi izinhlelo zokusebenza ze-hydroxypropyl methylcellulose ekuzilinganiseni?

I-Hydroxypropyl methylcelluloseivame ukusetshenziswa ezimbonini ezihlukahlukene. Nakuba abantu abaningi bengayiqondi kahle, ithinta izimboni ezihlukahlukene. Enkambweni yokwakhiwa kwemboni yezokwakha, ngokuvamile isetshenziselwa ukwakha udonga kanye nomhlobiso we-stucco, i-Caulking kanye nezinye izinkambu zokwakha imishini, ikakhulukazi ekwakhiweni kokuhlobisa, kuvame ukusetshenziselwa ukufakwa kwamathayela, imabula, neminye imihlobiso yepulasitiki. Inezinga eliphezulu lokunamathela futhi linganciphisa inani likasimende elisetshenzisiwe. Isetshenziswa embonini yokumboza, ikakhulukazi esetshenziswa njenge-thickener, ingenza ungqimba lube luhle futhi lugqame, akulula ukususa impushana, luthuthukise ukusebenza kokulinganisa, njll., ikakhulukazi ekusetshenzisweni emkhakheni wokwakha udaka lokuzilinganisa.

Umklomelo wesihlabathi esizilinganisa ngokwawo uwumkhiqizo okhethekile wodaka oluxutshwe okomile onemisebenzi yokulinganisa nokuzihlanganisa. Amakhono ayo okuzihlanganisa kanye nokuzilinganisa abaluleke kakhulu ekuzuzeni ungqimba lomhlabathi olungenamthungo nobushelelezi. Ngemikhiqizo emihle yokuzilinganisa, okokuqala Kufanele ibe nokusebenza okufanele, futhi ikwazi ukugcina ukusebenza kwayo kokulingana okuphelele kanye nekhono lokuziphilisa ngaphakathi kwesikhathi sokwakha. Ngale ndlela, lokhu kudinga udaka ukuze uqinisekise ngokugcwele ukuzinza nokufana kwalo phakathi nalesi sikhathi. Okwesibili, udaka kumele lube namandla athile, okuhlanganisa amandla okuthwala kanye namandla okubopha endaweni yesisekelo. Lezi yizimo eziyisisekelo zokusetshenziswa okujwayelekile kwezinto zokuzilinganisa, futhi ukugcwaliseka kwalezi zakhiwo zokuzilinganisa kudinga i-hydroxypropyl ukungezwa kwe-methyl cellulose ether kungashubisa futhi kwandise i-viscosity, futhi kunezici zokugcinwa kwamanzi aphezulu nokwandisa isikhathi sokwakha.

Uma iphezulu i-viscosity ye-hydroxypropyl methylcellulose, kungcono i-viscosity yezinto ezisekelwe kusimende, kodwa uma i-viscosity iphezulu kakhulu, izophazamisa uketshezi nokusebenza kwempahla. Ukwengeza, umphumela wokujiya we-hydroxypropyl methylcellulose nawo ungakhuphula isidingo samanzi sezinto ezisekelwe kusimende, ngaleyo ndlela kwandise isivuno sodaka. Udaka oluzilinganisa kanye nokhonkolo ozihlanganisayo, odinga uketshezi oluningi, kudinga i-viscosity ephansi ye-hydroxypropyl methylcellulose. I-low-viscosity cellulose ether ingadlala umphumela omuhle wokumisa, ivimbele i-slurry ekuzinzeni, futhi futhi inomsebenzi wokopha, ongaqinisekisa ukuthi ngeke uthinte umphumela wokugeleza we-self-leveling mortar material, kulula ukwakha, futhi inokugcinwa kwamanzi okuphezulu.

IHydroxypropyl methylcellulose isetshenziswa kabanzi ezintweni zokwakha ezahlukahlukene. Uma isetshenziselwa udaka oluzilinganisa, lunezici ezilandelayo:

1. Ukusebenza okuphezulu kokugcina amanzi kungandisa isikhathi sokusebenza kodaka oluzilinganisa ngokwalo, kuthuthukise ukuqina kodaka, kukhuphule amandla ayo okubopha, kanye nokusebenza okuhle kakhulu kwesibopho esimanzi kunganciphisa umlotha wokuhlala.

2. Ukuhambisana okuqinile, okufanelekile kuzo zonke izinhlobo zezinto zokwakha, udaka lokuzilinganisa, ukunciphisa isikhathi sokucwila, ukunciphisa izinga lokushwabana kwawo okomisa, nokugwema izinkinga ezinjengokuqhekeka nokushaya izigubhu kwezindonga naphansi.

3. Vimbela ukopha, kungadlala indima engcono ekumisweni, kuvimbele i-slurry kusuka ku-sedimentation nokusebenza okungcono ukopha.

4. Gcina ukusebenza kahle kokugeleza, i-viscosity ephansi yei-hydroxypropyl methylcellulosengeke kuthinte ukugeleza kwe-slurry, ukwakhiwa okulula, ukusebenza kahle kokugcinwa kwamanzi okuqondile, kungaveza umphumela omuhle wendawo ngemva kokuzilinganisa, futhi kugweme ukuqhekeka esimweni sezigubhu, ukusebenza okuzinzile kokubopha kwe-cellulose ether kuqinisekisa ngokugcwele uketshezi oluhle kanye nekhono lokuzilinganisa. Ukulawula izinga lokugcinwa kwamanzi kungakwenza aqine ngokushesha futhi kunciphise ukushwabana nokuqhekeka.
