Mu ifu, sima na gypsum,HPMCHydroxypropyl methylcellulose ether ahanini igira uruhare mu kubika no gukuba amazi, kandi ishobora kunoza neza uburyo amazi afatwa n’uko agwa. Ibintu nk'ubushyuhe bw'umwuka, ubushyuhe n'umuvuduko w'umuyaga bigira ingaruka ku gipimo cyo guhindagurika kw'amazi mu bicuruzwa bya putty, sima na gypsum. Kubwibyo, mu bihe bitandukanye, hari itandukaniro mu ngaruka zo kubika amazi ku bicuruzwa bifite HPMC zingana. Mu buryo bwihariye, ingaruka zo kubika amazi ku bicuruzwa bishobora guhindurwa binyuze mu kongera cyangwa kugabanya ingano ya HPMC.
Kubika amazi muri ether ya methyl cellulose mu gihe cy'ubushyuhe bwinshi ni ikimenyetso cy'ingenzi cyo gutandukanya ubwiza bwa ether ya methyl cellulose. Ibikoresho byiza cyane bya HPMC bishobora gukemura neza ikibazo cyo kubika amazi mu gihe cy'ubushyuhe bwinshi. Mu bihe by'ubushyuhe bwinshi, cyane cyane mu bice bishyushye n'ibyumye hamwe n'imiterere y'izuba rinini, HPMC nziza irakenewe kugira ngo yongere uburyo amazi abikwamo. HPMC nziza ishobora guhindura amazi ari muri mortier mo amazi ahambiriye, bityo ikagenzura neza uburyo amazi ahinduka bitewe n'ubushyuhe bwinshi kandi ikagera ku buryo amazi abikwamo menshi.
Selulosi ya methyl nziza ishobora gukwirakwizwa neza kandi neza mu buryo bungana mu gishishwa cya sima n'ibikomoka kuri gypsum, igapfunyika uduce twose tw’ingenzi, igakora agahu ko kunywesha, maze amazi akazarekurwa buhoro buhoro mu gihe kirekire. Habaho uburyo bwo guhumeka, bityo bigatuma ibikoresho bikomera kandi bigakomera. Kubwibyo, mu bwubatsi bw’impeshyi bushyuha cyane, kugira ngo amazi agerweho, ni ngombwa kongeramo ibicuruzwa bya HPMC byiza mu bwinshi buhagije hakurikijwe formula. Iyo hakoreshejwe HPMC ivanze, amazi adahagije, imbaraga nke, gucika, n’icyuho kizaba bitewe no kuma cyane. Ibibazo by’ubuziranenge nk’ingoma no gucika nabyo byongera ingorane z’ubwubatsi ku bakozi. Uko ubushyuhe bugenda bugabanuka, ingano ya HPMC yongewemo ishobora kugabanuka buhoro buhoro, kandi ingaruka imwe yo kubika amazi ishobora kugerwaho.
Uburyo bwo gusubiza ibintu bugenzura neza ikorwa ryaHPMC, kandi gusimbuza kwayo ni kose kandi ni byiza cyane. Umuti wayo w'amazi urasobanutse kandi ubonerana, ufite imigozi mike y'ubusa. Kuba ihuye n'ifu ya rubber, sima, lime n'ibindi bikoresho by'ingenzi birakomeye cyane, bishobora gutuma ibikoresho by'ingenzi bikora neza cyane. Ariko, HPMC ifite uburyo bubi bwo gukora ifite imigozi myinshi y'ubusa, ikwirakwizwa ry'ibintu bisimburana, amazi mabi yo kubika n'indi miterere, bigatuma amazi ahinduka menshi mu gihe cy'ubushyuhe bwinshi. Ariko, icyo bita HPMC (ubwoko bw'ibinyabutabire) gifite umwanda mwinshi biragoye guhuza, bityo amazi yo kubika n'indi miterere birarushaho kuba bibi. Iyo hakoreshejwe HPMC itari nziza, ibibazo nk'ubudahangarwa buke bw'urubura, igihe gito cyo gufungura, ifu, gusenyuka, gupfuka no gusuka bizaterwa, ibyo bizongera ingorane mu bwubatsi kandi bigabanya cyane ubwiza bw'inyubako.
