Inganda z’ubwubatsi ku isi zirimo guhinduka vuba, bitewe n’ibikenewe cyaneibikoresho bikora neza cyane, uburyo bwihuse bwo kubaka, kunoza imikorere, no kunoza imikorereMu bikoresho by'ubwubatsi bigezweho,mortilaire zikozwe muri gypsumbyarushijeho kuba ingenzi bitewe n’imiterere yabyo yoroshye, kurwanya umuriro, kurangiza neza, no koroshya kuyikoresha.
Uko isoko rya plasta za gypsum, imvange z’ingingo, sisitemu zo kwipima, na mortiers zo gushushanya zigenda ziyongera, abakora ibintu barimo kwibanda ku kunoza imiterere binyuze mu nyongeramusaruro zigezweho. Muri izi nyongeramusaruro,eteri y'ibishyimboyagaragaye nk'ikintu cy'ingenzi kubera imiterere yayo yihariye mu mikorere y'imitsi n'amazi.
Iyo bihujwe na ether za cellulose nka HPMCnaMHEC, eteri y'ibishyimbo itanga umusaruro utangajeingaruka zihuriweho, binoza cyane imikorere ya mortilari zishingiye kuri gypsum.
Iyi nkuru irasuzuma imiterere, uburyo, ikoreshwa, n'amahirwe y'ejo hazaza ya eteri ya sitashi mu buryo bwa morti ishingiye kuri gypsum.
1. Gusobanukirwa imyuka ishingiye kuri Gypsum
Mota zikozwe muri Gypsum ni ibikoresho by'ubwubatsi byumye bigizwe ahanini na:
