Hydroxypropyl methyl cellulose muri sima na plaster ishingiye kuri gypsum

HPMC Hydroxypropyl methyl celluloseMu sima na gypsum, ahanini bigira uruhare mu kubika amazi no kuyagwingira, bishobora kunoza neza uburyo slurry ifatana n'amazi kandi ikananirwa kuyagwa.

Ubushyuhe bw'umwuka, ubushyuhe n'umuvuduko w'umuyaga bishobora kugira ingaruka ku muvuduko w'amazi mu byuma bya sima n'ibikomoka kuri gypsum. Rero mu bihe bitandukanye, kongeramo hydroxypropyl methyl cellulose ingano imwe y'umusaruro w'amazi igira itandukaniro. Mu miterere ya sima, ingaruka zo kubika amazi mu mazi zishobora guhindurwa no kongera cyangwa kugabanya ingano ya HPMC. Kubika amazi mu mazi mu mazi mu gihe cy'ubushyuhe bwinshi ni ikimenyetso cy'ingenzi cyo gutandukanya ubwiza bwa methyl cellulose ether.

Nibyiza cyaneselulose ya hydroxypropyl methylIbikoresho by’uruhererekane bishobora gukemura neza ikibazo cyo kubika amazi mu gihe cy’ubushyuhe bwinshi. Mu gihe cy’ubushyuhe bwinshi, cyane cyane ahantu hashyushye kandi humutse no mu buryo bworoshye bwo kubaka ku ruhande rw’izuba, hakenewe HPMC nziza kugira ngo hongerwe uburyo amazi abikwamo; hydroxypropyl methyl cellulose (HPMC), uburinganire ni bwiza cyane, ni itsinda rya hydroxypropyl ya ogisijeni na ogisijeni ikwirakwira ku buryo bungana ku ruhererekane rwa cellulose, ishobora kongera ogisijeni ya hydroxyl na ether n’amazi ku buryo bw’ingenzi bwo guhuza hydrogen, bigatuma amazi arushaho kuba meza, kugira ngo igenzure neza ubushyuhe buterwa n’ubushuhe buhita bushira, igere ku kubika amazi menshi.

Ubwiza bwo hejuru bwa hydroxypropyl methyl cellulose bushobora gukwirakwira mu buryo bumwe kandi neza mu bintu bya sima na plaster, kandi bugapfunyika uduce twose tw’ingenzi, kandi bugakora urwego rw’icyuma gitose, ubushuhe mu rufatiro igihe kirekire bugasohoka buhoro buhoro, kandi bugatuma ibintu bidakora neza, kugira ngo bikomeze gukomera no gukomera kw’ibikoresho.

Mu bwubatsi, kugira ngo hagerwe ku ngaruka zo kubungabunga amazi, hakenewe kongeramo ubuziranengeHPMCibicuruzwa hakurikijwe formula, bitabaye ibyo, hazabaho kuma vuba cyane bitewe n’amazi adahagije, kugabanuka kw’imbaraga, kwangirika, ibibazo by’ubuziranenge bw’ingomero no gushonga kw’amazi, ariko nanone byongera ingorane z’abakozi mu bwubatsi. Uko ubushyuhe bugenda bugabanuka, ingano y’amazi ya HPMC ishobora kugabanuka buhoro buhoro, kandi ingaruka imwe yo kubika amazi ishobora kugerwaho.
