Muri sima ya sima hamwe na gypsumu ishingiye kuri slurry, hydroxypropyl methylcellulose igira uruhare runini mu gufata amazi no kubyimba, kandi irashobora kunoza neza kwifata no kurwanya sag.
Ibintu nkubushyuhe bwikirere, ubushyuhe numuvuduko wumuyaga bizagira ingaruka kumuvuduko wamazi mumazi ya sima nibicuruzwa bishingiye kuri gypsumu. Kubwibyo, mubihe bitandukanye, hariho itandukaniro mubikorwa byo gufata amazi yibicuruzwa hamwe na hydroxypropyl methylcellulose yongeyeho. Mu bwubatsi bwihariye, ingaruka zo gufata amazi ya slurry zirashobora guhinduka mukwongera cyangwa kugabanya umubare wa HPMC wongeyeho. Kubika amazi mugihe cy'ubushyuhe bwo hejuru nikimenyetso cyingenzi cyo gutandukanya ubwiza bwa hydroxypropyl methylcellulose ether.
Ibicuruzwa byiza bya hydroxypropyl methylcellulose birashobora gukemura neza ikibazo cyo gufata amazi munsi yubushyuhe bwinshi. Mu bihe by'ubushyuhe bwinshi, cyane cyane ahantu hashyushye kandi humye no kubaka ibice bito ku ruhande rw'izuba, HPMC yo mu rwego rwo hejuru irasabwa kunoza uburyo bwo gufata neza amazi. HPMC yo mu rwego rwo hejuru ifite uburinganire bwiza cyane. Amatsinda ya methoxy na hydroxypropoxy agabanijwe neza kumurongo wa selile ya selile, ushobora kuzamura ubushobozi bwa atome ya ogisijeni kuri hydroxyl na ether ihuza amazi kugirango ikore hydrogene. , kugirango amazi yubusa ahinduke amazi aboshye, kugirango agenzure neza ihinduka ryamazi yatewe nikirere cyinshi, kandi agere kumazi menshi.
Hydroxypropyl methylcellulose yo mu rwego rwo hejuru irashobora gukwirakwizwa kimwe kandi neza mugisima cya sima na gypsumu, hanyuma igapfunyika ibice byose bikomeye, hanyuma igakora firime itose, kandi ubuhehere buri mukibanza burekurwa buhoro buhoro mugihe kirekire, kandi reaction ya hydrata hamwe nibikoresho bya gelique kugirango imbaraga zifatika hamwe nimbaraga zo kwikuramo ibintu.
Kubwibyo, mubwubatsi bwubushyuhe bwo hejuru bwizuba, kugirango tugere ku ngaruka zo gufata amazi, birakenewe kongeramo ibicuruzwa byiza bya HPMC mubwinshi buhagije ukurikije formulaire, bitabaye ibyo, hazabaho hydrated idahagije, kugabanuka kwingufu, guturika, gutobora no kumeneka biterwa no gukama cyane. ibibazo, ariko kandi byongere ingorane zo kubaka abakozi. Mugihe ubushyuhe bugabanutse, ingano ya HPMC yongeweho irashobora kugabanuka buhoro buhoro, kandi ingaruka zimwe zo gufata amazi zirashobora kugerwaho.
