Viscosity nibintu byingenzi bigize ibintu bya selile ether. Muri rusange, uko ubukonje buri hejuru, ningaruka nziza yo kugumana amazi ya gypsum. Nyamara, uko ubukonje buri hejuru, niko uburemere bwa molekuline ya selile ya selile, kandi imbaraga za selile ya selile igabanuka uko bikwiye. Iyo hejuru ya viscosity, niko bigaragara ingaruka zo kubyimba ni, ariko ntabwo zingana. Iyo hejuru ya viscosity, niko gufatana na minisiteri itose izaba, mubwubatsi, imikorere yo gufatisha scraper hamwe no gufatira hejuru kuri substrate. Ariko ntabwo ari byiza kongera imbaraga zimiterere ya minisiteri yonyine. Mubyongeyeho, mugihe cyo kubaka, imikorere ya wet mortar anti-sagging ntabwo igaragara. Ibinyuranye, Methyl selulose yahinduwe ifite ubukonje buke kandi buciriritse bwerekanaga iterambere ryimbaraga zimiterere ya minisiteri itose. Kubaka ibikoresho byurukuta ahanini byubatswe, bifite amazi. Kandi ibikoresho byubaka gypsumu bikoreshwa mukubaka urukuta, nyuma yo kongeramo modulasiyo yamazi kurukuta, ubuhehere biroroshye kwinjizwa nurukuta, bigatuma gypsumu ibura ubushuhe bukenewe mumazi, bigatera ingorane zo kubaka plastike no kugabanya imbaraga zububiko. , bityo hariho uduce, ingoma zidafite ishingiro, gusuka nibindi bibazo byiza. Kunoza gufata neza ibikoresho byubaka gypsumu birashobora gukemura ikibazo cyubwubatsi no kunoza imbaraga zihuza urukuta. Kubwibyo, ibikoresho bigumana amazi byabaye kimwe mubyongeweho byingenzi byubaka gypsumu.
Mu rwego rwo koroshya iyubakwa, ibikoresho by'ifu yubaka nka pompe, pompe yometseho, bifatanyiriza hamwe na pasteri, hamwe na gypsum retarder byongewe mubikorwa kugirango byongerwe igihe cyo kubaka paste, kuko inzira yo kuvura hydihydrate gypsum irabujijwe kongeramo retarder kuri gypsumu, ubu bwoko bwa paste gypsum bugomba kuguma kurukuta amasaha 1-2 mbere yo gushiraho, kandi inkuta nyinshi zifite amazi imitungo yo kwinjiza, cyane cyane, ibikoresho bishya byoroheje byurukuta nkurukuta rwamatafari, urukuta rwa beto rwumuyaga, imbaho zometse kumashanyarazi, kugirango rero hakorwe uburyo bwo gufata amazi yo gufata amazi ya gypsum, kugirango wirinde kwimura amwe mumazi mabi kurukuta, itera gypsum paste ikomera mugihe ibura ryamazi, hydrated ituzuye, itera gypsum hamwe nurukuta hejuru yurukuta rwahujwe gutandukana, igikonoshwa. Ongeramo ibikoresho bigumana amazi nugukomeza ubuhehere buri muri paste ya gypsumu, kugirango hamenyekane hydrata ya paste ya gypsum kuri interineti, bityo bikomeze gukomera. Ibikoresho bisanzwe bigumana amazi ni selile ya selile, nka Methyl selulose (MC), hypromellose (HPMC), hydroxyethyl methyl selulose (HEMC), n'ibindi. Byongeye kandi, inzoga za polyvinyl, sodium alginate, ibinyamisogwe byahinduwe, diatomite nifu yubutaka budasanzwe nabyo birashobora gukoreshwa mugutezimbere amazi.
