I-HPMC ku-Wet Mortars
I-JINJI® Hydroxypropyl Methyl Cellulose (HPMC) iyi-polymer ye-cellulose ether engeyona i-ionic esekelwe ku-cellulose, i-polymer yemvelo etholakala ku-linter kakotini ecolisisiwe.
I-HPMC ingathuthukisa ukuhlangana nokugcinwa kwamanzi kwengxube ye-Spray mortar.
Izinga lokugcinwa kwamanzi liyinkomba ebalulekile yokusebenza kwe-Spray Mortar. Nakuba ezinye izingxenye zodaka nokhonkolo zifana, zisebenza ngendlela ehlukile. Ngokuvamile, ukhonkolo uthululelwa ukhonkolo kanye nomsebenzi wokhuni ogcina amanzi amaningi. Udaka ngokuvamile lusetshenziswa ezindaweni ezimunca amanzi, futhi umswakama osesihlabathini ulahleka kalula noma uhwamuke emkhathini, ngakho ukugcinwa kwamanzi odaka kuba okubaluleke kakhulu kunokhonkolo.
Isizathu sokuthi kungani i-HPMC ithuthukisa ukungaguquguquki kodaka lwesifutho wukugcina amanzi, ingathuthukisa ukuhlangana kodaka, inciphise izinga lokopha kodaka ngokwezinga elithile, kodwa ithuthukise ukugeleza kodaka lwesifutho ngaphakathi kwebanga elithile lomthamo; Kodwa-ke, okuqukethwe okuphezulu kwe-Hydroxpropyl Methyl Cellulose kwenza udaka lwengxube emanzi luhlangane kakhulu, okunciphisa uketshezi lodaka futhi kwenze udaka lube inselele ngokwengeziwe ukwakha.
I-HPMC ingakhuphula amandla okubopha okuqinile kodaka oluxutshwe okumanzi.
Ngodaka lokunamathisela, amandla ebhondi ayinkomba ebalulekile. Ngokuvamile, udaka lodaka ludinga ukusebenza kahle. Ukuze wenze ungqimba olufana nodaka endaweni yokwakha. Amandla okubopha okuqinile odaka angenza udaka kanye nongqimba lwesisekelo luboshwe ngokuqinile, futhi ukusetshenziswa kwesikhathi eside ngeke kubangele ukuqhekeka nokuwa.
I-cellulose ether kanye nezinhlayiya ze-hydration zakha ungqimba oluncane lwefilimu ye-polymer enomphumela wokuvala futhi ivimbele ukulahlekelwa kwamanzi, ngokugcinwa kahle kwamanzi, ukuze ibe nomswakama owanele wokuqinisekisa ukuthuthukiswa kwe-hydration namandla kasimende futhi kuthuthukise amandla okubopha. lokunamathisela. Ngakolunye uhlangothi, i-Hydroxpropyl Methyl Cellulose ithuthukisa ukubumbana kodaka lwesifutho ukuze kuqinisekiswe ukwakheka kwayo okuhle kwepulasitiki nokuguquguquka, inciphisa ukucindezeleka kokushelela phakathi kodaka lwesifutho nesixhumi esibonakalayo se-substrate, futhi ithuthukisa nakakhulu ikhono lokuhlanganisa esibonakalayo sodaka.
Kunconywa ukuthi ngesikhathi senqubo yokulungiselela, i-HPMC ixubene nodaka lwe-spray ngendlela yesisombululo kunokuba ihlanganiswe ngokuqondile nefomu lempushana.
Owokuqala unomphumela ongcono ekuthuthukiseni ukugcinwa kwamanzi, ukuhlangana, kanye nezakhiwo zemishini zodaka lwesifutho. Lapho okuqukethwe okuguquliwe kwe-Hydroxpropyl Methyl Cellulose kuku-0.01%~0.04%, izinga lokugcinwa kwamanzi le-HPMC efomini lesixazululo lingaphezulu ngo-1.4%~3.0% kunele-HPMC eyimpuphu osikeni lwesifutho. Ngakho-ke, i-HPMC exutshwe ngendlela yesisombululo inomphumela ongcono ekuthuthukiseni ukugcinwa kwamanzi kwe-spray mortar.
