Ubukonje bwinshi bwa selulose ether burashobora kunoza imikorere yo gufata amazi ya gypsum?

Viscosity nikintu cyingenzi cyimikorere ya selile ether.

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 bifasha cyane kongera imbaraga zimiterere ya minisiteri itose ubwayo. Mubyongeyeho, mugihe cyo kubaka, imikorere ya anti-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 inkuta byateguwe hongerwaho amazi kurukuta, kandi amazi akinjira byoroshye kurukuta, bikaviramo kubura amazi akenewe kugirango hydrès ya gypsumu, bikaviramo ingorane zo kubaka plaque no kugabanya imbaraga zubucuti, bikaviramo gucika, ibibazo byubuziranenge nko gutobora no gutobora. Kunoza gufata neza ibikoresho byubaka gypsumu birashobora kunoza 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. Kubera ko gypsumu ivanze na Retarder, ibuza inzira ya hydration ya gypsumu ya hemihydrate. Ubu bwoko bwa gypsum slurry bugomba kubikwa kurukuta rwa 1 ~ 2H mbere yuko rushyiraho. Inkuta nyinshi zifite imiterere yo gufata amazi, cyane cyane inkuta zamatafari na beto ya gaz. Urukuta, ikibaho cyiziritse hamwe nibindi bikoresho byoroheje byurukuta, bityo rero gufata neza gufata amazi bigomba gukorwa kuri gypsum kugirango hirindwe kwimura igice cyamazi muri ruhurura kurukuta, bikaviramo kubura amazi hamwe n’amazi atuzuye mugihe gypsumu ikomye. Tera gutandukana no gukuramo 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.

Ntakibazo cyaba kigumya gufata amazi gishobora gutinda umuvuduko wa gypsumu kurwego rutandukanye, mugihe dosiye ya retarder idahindutse, umukozi ushinzwe gufata amazi arashobora guhagarika igenamiterere muminota 15-30. Kubwibyo, umubare wabadindiza urashobora kugabanuka muburyo bukwiye.
