Bitewe nubwiza bwayo bwimiterere nuburyo bwimiterere, gypsumu nibikoresho byiza byubaka kandi ikoreshwa cyane mumasoko yimitako yimbere mugihugu no mumahanga.Nyamara, kubera ko gypsumu ishyiraho kandi igakomera vuba, igihe cyakazi ni iminota 3 kugeza 30, byoroshye kugabanya ikoreshwa rya gypsumu.Kubwibyo, ni ngombwa cyane kongeramo gypsum retarder.
Mugihe retarder ihindura igihe cyo kudindiza gypsumu, nayo yangiza cyane imbaraga.
Ibyiza bya gypsum retarder:
Ongeraho amafaranga make, igihe kinini cyo kudindiza
Gukomera cyane nyuma ya coagulation, idafite uburozi, uburyohe kandi bwangiza ibidukikije
1. Banza uvange ifu ya gypsum yubaka na retarder, Yuhe hydroxypropyl methylcellulose cyangwa izindi nyongeramusaruro zingana, hanyuma ushyiremo umucanga, calcium iremereye, nibindi, ongeramo umucanga cyangwa calcium iremereye hanyuma ubireke muminota 15 mbere yo kurekura.(Icyitonderwa: Bitewe n'uburemere butandukanye bwibikoresho, hazabaho gutondekanya nyuma yigihe kirekire, bizagira ingaruka kubicuruzwa.)
2. Kubindi bicuruzwa, nka gypsumu yububiko hamwe namazi meza ya gel, ushobora gushyira retarder mumazi mbere, hanyuma ukayongeramo kugirango ukoreshe nyuma yo gushonga.
Gutegura ibintu bifatika bya gypsumu
