Kuki wongera hydroxypropyl methylcellulose (HPMC) kuri minisiteri ishingiye kuri gypsumu

Muri sima ya sima na gypsumu ishingiye kuri slurry,hydroxypropyl methylcellulosecyane cyane igira uruhare mu gufata amazi no kubyimba, bishobora kunoza neza ubumwe hamwe 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.Kugumana amazi ya methyl selulose ether ku bushyuhe bwo hejuru ni ikimenyetso cyingenzi cyo gutandukanya ubwiza bwa methyl selulose ether.

Ibicuruzwa byiza bya hydroxypropyl methylcellulose birashobora gukemura neza ikibazo cyo gufata amazi mubushyuhe 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, imikorere yayo ya hydroxypropoxy ikwirakwizwa mu buryo bwuzuye ku murongo wa selile ya selile, ishobora kuzamura ubushobozi bwa atome ya ogisijeni kuri hydroxyl na ether ihuza amazi kugira ngo ihuze imigozi ya hydrogène, ku buryo amazi yubusa ahinduka amazi aboshye, kugirango agenzure neza ihinduka ryamazi yatewe nubushyuhe bwo hejuru kandi bigere kumazi menshi.Amazi arakenewe kugirango hydrasiyo ashyireho ibikoresho bya sima nka sima na gypsumu.Umubare nyawo wa HPMC urashobora kubika amazi muri minisiteri ndende bihagije kugirango igenamigambi no gukomera bikomeze.

Umubare wa HPMC usabwa kugirango ubone ubushobozi buhagije bwo gufata amazi biterwa na:

1. Kwinjira kwurwego rwibanze

2. Ibigize minisiteri

3. Ubunini bwa minisiteri

4. Amazi asabwa na minisiteri

5. Igihe cyo gushiraho ibikoresho bya sima

Hydroxypropyl methylcellulose yo mu rwego rwo hejuru irashobora gukwirakwizwa kimwe kandi neza mugisima cya sima hamwe nibicuruzwa bishingiye kuri gypsumu, hanyuma igapfunyika ibice byose bikomeye, hanyuma igakora firime itose, kandi ubuhehere buri mukibanza bukarekurwa buhoro buhoro igihe kirekire., hamwe na hydration reaction ibaho hamwe nibikoresho bya simaitiki bidafite ingufu, bityo bigatuma imbaraga zihuza nimbaraga zo kwikuramo ibintu.

Kubwibyo, mubwubatsi bwubushyuhe bwo hejuru bwubushyuhe, kugirango tugere ku ngaruka zo gufata amazi, birakenewe ko hongerwaho ibicuruzwa byiza bya HPMC muburyo buhagije ukurikije formulaire, bitabaye ibyo, hazabaho hydrated idahagije, kugabanya imbaraga, gucamo, gutobora no kugwa biterwa no gukama vuba.Byongera kandi ingorane zo kubaka kubakozi.Mugihe ubushyuhe bugabanutse, umubare wiyongereye wa HPMC urashobora kugabanuka buhoro buhoro, kandi ingaruka zimwe zo gufata amazi zirashobora kugerwaho.
