Muri rusange, uko ubukonje buri hejuru, niko ingaruka nziza yo gufata amazi ya gypsum. Nyamara, uko hejuru yubukonje, niko uburemere bwa molekuline ya selile ya selile, hamwe no kugabanuka gukwiranye kwayo bizagira ingaruka mbi kumbaraga no mumikorere yubwubatsi. Iyo hejuru yubukonje, niko bigaragara ingaruka zo kubyimba kuri minisiteri, ariko ntabwo ihwanye neza.
Iyo hejuru yubukonje, niko amabuye atose azaba menshi. Mugihe cyo kubaka, bigaragarira nko kwizirika kuri scraper no gufatira hejuru kuri substrate. Ariko ntabwo ari byiza kongera imbaraga zimiterere ya minisiteri yonyine. Mubyongeyeho, mugihe cyo kubaka, imikorere irwanya sag ya minisiteri itose ntabwo igaragara. Ibinyuranye na byo, bimwe mu biciriritse kandi bito ariko byahinduwe na methyl selulose ethers bifite imikorere myiza mugutezimbere imiterere yimiterere ya minisiteri.
Kubaka ibikoresho byurukuta ahanini byubatswe, kandi byose bifite amazi akomeye. Nyamara, ibikoresho byubaka gypsumu bikoreshwa mukubaka urukuta byateguwe hongerwaho amazi kurukuta, kandi amazi yakirwa byoroshye nurukuta, bikaviramo kubura amazi akenewe kugirango hydrès ya gypsumu, bikaviramo ingorane zo kubaka plasta kandi bikagabanuka imbaraga zubusabane, bikavamo gucikamo, Ibibazo byubuziranenge nko gutobora no gukuramo. Kunoza amazi yo kubika ibikoresho byubaka gypsumu birashobora kuzamura ubwubatsi nimbaraga zo guhuza urukuta. Kubwibyo, ibikoresho byo kubika amazi byabaye kimwe mubintu byingenzi bivangwa na gypsumu.
Gukoresha gypsumu, gypsumu ihujwe, gypsum ya caulking, gypsum putty nibindi bikoresho byifu yububiko. Mu rwego rwo koroshya ubwubatsi, gypsum retarders yongerwaho mugihe cyumusaruro kugirango yongere igihe cyo kubaka gypsum. Kuberako gypsumu ivanze na Retarder, ibuza inzira ya hydrata ya hemihydrate gypsum. Ubu bwoko bwa gypsum slurry bugomba kubikwa kurukuta kumasaha 1 kugeza kuri 2 mbere yuko bushiraho. Inkuta nyinshi zifite imiterere yo kwinjiza amazi, cyane cyane inkuta zamatafari na beto ya gaz. Urukuta, ikibaho cyiziritse hamwe nibindi bikoresho bishya byoroheje byurukuta, bityo rero uburyo bwo gufata amazi bugomba gukorerwa kuri gypsum kugirango hirindwe kwimura igice cyamazi muri ruhurura kurukuta, bikaviramo ikibazo cyo kubura amazi hamwe n’amazi atuzuye mugihe gypsumu gusebanya birakomeye. Tera gutandukana no gutobora ingingo hagati ya gypsumu nubuso bwurukuta. Kwiyongera kubintu bigumana amazi nugukomeza ubuhehere buri muri gypsum, kugirango hamenyekane hydrasiyo ya gypsum slurry kuri interineti, kugirango habeho imbaraga zo guhuza. Ibikoresho bikoreshwa cyane mu gufata amazi ni selile ya selile, nka: methyl selulose (MC), hydroxypropyl methyl selulose (HPMC), hydroxyethyl methyl selulose (HEMC), nibindi. ifu yisi idasanzwe, nibindi birashobora kandi gukoreshwa mugutezimbere imikorere yamazi.
Nuburyo ki bwo kubika amazi bushobora gutinza umuvuduko wa gypsumu kurwego rutandukanye, mugihe ingano ya retarder idahindutse, umukozi ubika amazi arashobora
mubisanzwe usubire gushiraho muminota 15-30. Kubwibyo, umubare wabadindiza urashobora kugabanuka muburyo bukwiye.
