Iyo HPMC igeze kuri gypsum ya pompe, kugira inyongeramusaruro yizewe kandi ikora neza ningirakamaro kugirango tumenye imikorere myiza nibisubizo biramba. Kimwe mubyongeweho bimaze kumenyekana cyane mumyaka yashize ni Hydroxypropyl Methyl selulose, izwi nka HPMC. Gutanga inyungu zitandukanye, HPMC yahindutse igisubizo kubanyamwuga mubikorwa byubwubatsi.
Imwe mu nyungu zingenzi zo gukoresha HPMC kuri gips ya gypsum ni umutungo wacyo wo kubika amazi cyane. Ibi bivuze ko ishobora gufata neza no kugenzura ubwinshi bwamazi muruvange, ikazamura imikorere ya plaster. Ibice bya HPMC bigize firime yoroheje ikikije molekile y'amazi, ikabuza guhumuka vuba. Nkigisubizo, plaster iguma mumikorere yigihe kinini, itanga umwanya uhagije wo gusaba no kurangiza.
Usibye ubushobozi bwo gufata amazi, HPMC itanga kandi igihe kirekire cyo gufungura, nikindi kintu gikomeye kiranga gushakishwa muri progaramu ya gypsumu. Umwanya muremure ufunguye bivuga igihe plaster ikomeza kuba ingirakamaro kumurimo utarumye vuba. HPMC ifasha kongera iki gihe, igaha abanyamwuga guhinduka kugirango bakore ku muvuduko bifuza. Haba kubisabwa kurukuta, hejuru, cyangwa mubindi bikoresho bya gypsumu, HPMC iremeza ko plaster ikomeza kuba muburyo bukoreshwa, bikagabanya ibyago byo gusesagura no kongera umusaruro kurubuga rwakazi.
Ikigeretse kuri ibyo, HPMC ikora nkumubyimba muri gypsumu, itanga umusanzu wifuzwa hamwe nibicuruzwa byanyuma. Ifasha kurema ubuso bunoze kandi bumwe, kugabanya kuba hari ubusembwa nkibice, kugabanuka, no kugabanuka. Hamwe numubare ukwiye wa HPMC, abashoramari nabubatsi barashobora kugera kurwego rwohejuru rwujuje ubuziranenge bwujuje ubuziranenge kandi burambye.
Ubwinshi bwa HPMC kuri gypsum plaster nayo ikwiye kwitonderwa. Irashobora gukoreshwa muburyo butandukanye bwo gukoresha, harimo nuburyo bwo gukoresha imashini. Byongeye kandi, HPMC irahujwe nubwoko butandukanye bwinyongera zikoreshwa muri pompe ya gypsumu, nka moteri yihuta, retarders, hamwe nibintu byinjira mu kirere. Ubu buryo bwinshi butuma HPMC ihitamo neza kubanyamwuga bashaka guhuza imvange ya gypsumu ivangwa nibisabwa byumushinga.
Ntabwo HPMC ifite akamaro gusa mugukoresha no gukora gypsumu, ariko kandi yangiza ibidukikije. HPMC ni uruganda rudafite uburozi kandi rushobora kwangirika, rukagira amahitamo meza kandi arambye kubikorwa byubwubatsi. Kamere yacyo ishingiye kumazi irusheho kunoza ibidukikije byangiza ibidukikije, kuko bigabanya kwishingikiriza ku nyongeramusaruro.
Mu gusoza, HPMC ya plaque gypsum itanga ibyiza byinshi byujuje ibyifuzo byinzobere mubikorwa byubwubatsi. Itanga ibintu byifuzwa cyane nko kubika amazi, igihe kirekire gifunguye, kandi ikora nkumubyimba. Hamwe na HPMC, abashoramari n'abubatsi barashobora kugera kubikorwa byiza, kongera umusaruro, no kurangiza neza. Guhindura byinshi hamwe no kubungabunga ibidukikije bikomeza gushimangira umwanya wacyo nkinyongera yizewe kandi ikora neza ya progaramu ya gypsumu.
