Hydroxypropyl methyl selulose muri sima na gypsumu ishingiye kuri plaster

HPMC Hydroxypropyl methyl selulose muri sima ya sima na gypsum slurry, cyane cyane igira uruhare mukubika amazi no kubyimba, birashobora kunoza neza kwifata no kurwanya sag.

Ubushyuhe bwo mu kirere, ubushyuhe n’umuvuduko w’umuyaga birashobora kugira ingaruka ku gipimo cy’amazi yo mu mazi ya sima na gypsumu.Mu bihe bitandukanye rero, wongeyeho hydroxypropyl methyl selulose ingana ningaruka zingaruka zo gufata amazi yibicuruzwa bifite itandukaniro.Mu iyubakwa rya beto, ingaruka zo gufata amazi ya slurry zirashobora guhinduka mukwongera cyangwa kugabanya umubare wa HPMC.Kugumana amazi ya methyl selulose ether ku bushyuhe bwo hejuru ni ikimenyetso cyingenzi cyo gutandukanya ubwiza bwa methyl selulose ether.

Ibicuruzwa byiza bya hydroxypropyl methyl selulose birashobora gukemura neza ikibazo cyo gufata amazi munsi yubushyuhe bwinshi.Mu gihe cy'ubushyuhe bwinshi, cyane cyane ahantu hashyushye kandi humye no kubaka igicucu cyoroshye ku zuba, hakenewe HPMC yo mu rwego rwo hejuru kugira ngo amazi agabanuke neza;hydroxypropyl methyl selulose (HPMC), uburinganire ni bwiza cyane, ni ogisijeni na ogisijeni hydroxypropyl matsinda bigabanijwe neza ku murongo wa selile, birashobora guteza imbere hydroxyl na ether ogisijeni n'amazi kumurongo wingenzi uhuza imbaraga za hydrogène, gukora amazi yubusa, kugirango ugenzure neza ikirere gishyushye giterwa nubushuhe bugenda bugera, Kugera kumazi menshi.

Ubwiza bwa hydroxypropyl methyl selulose burashobora gukwirakwiza kimwe kandi neza mubisaka bya sima na pompe, hanyuma bigapakira ibice byose bikomeye, hanyuma bigakora urwego rwa firime itose, ubuhehere buri mukibanza igihe kirekire bukarekurwa buhoro buhoro, hamwe nubutaka bwa cimentitifique butagira imbaraga. , kugirango tumenye imbaraga zububiko nimbaraga zo kwikuramo ibikoresho.

Mu iyubakwa, kugira ngo tugere ku ngaruka zo kubungabunga amazi, ugomba kongeramo ibicuruzwa byiza bya HPMC ukurikije formulaire, bitabaye ibyo, hazumishwa vuba cyane biterwa no kubura amazi adahagije, kugabanya imbaraga, kumena, kuvoma ingoma no kumena ubuziranenge ibibazo, ariko kandi byongere ingorane zo kubaka abakozi.Mugihe ubushyuhe bugabanutse, ubwinshi bwamazi HPMC irashobora kugabanuka buhoro buhoro, kandi ingaruka zimwe zo gufata amazi zirashobora kugerwaho.
