Hydroxypropyl methylcellulose ikoreshwa muburyo butandukanye bitewe nikirere

Ibintu nkubushyuhe bwikirere, ubushyuhe numuvuduko wumuyaga bizagira ingaruka kumuvuduko wubushuhe bwubushuhe bwa sima na gypsumu.Kubwibyo, mubihe bitandukanye, ingaruka zo gufata amazi zingana na HPMC ziratandukanye.

Mu bwubatsi bwihariye, ingaruka zo gufata amazi ya slurry zirashobora guhinduka mukongera cyangwa kugabanya umubare wa HPMC wongeyeho.Kugumana amazi ya hydroxypropyl methyl selulose ether mugihe cy'ubushyuhe bwo hejuru nikimenyetso cyingenzi cyo gutandukanya ubwiza bwa hydroxypropyl methyl selulose ether.Ibicuruzwa byiza bya HPMC birashobora gukemura neza ikibazo cyo gufata amazi kubushyuhe bwinshi.
Mu bihe by'ubushyuhe bwo hejuru, 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 rwohejuru ifite uburinganire bwiza cyane.Amatsinda ya methoxy na hydroxypropoxy bigabanijwe neza kumurongo wa selile ya selile, bishobora kunoza ubushobozi bwa atome ya ogisijeni kuri hydroxyl na ether ihuza amazi kugirango ibe ihuza hydrogène, kugirango amazi yubusa ahinduke amazi, bityo bigenzurwe neza guhumeka kwamazi guterwa nubushyuhe bwo hejuru, no kugera kumazi menshi.
Cellulose yo mu rwego rwohejuru HPMC irashobora gukwirakwizwa kimwe kandi neza mubutaka bwa sima na gypsumu, hanyuma ugapfunyika ibice byose bikomeye, hanyuma ugakora firime itose.Amazi muri base arekurwa buhoro buhoro mugihe kirekire.Ibikoresho byegeranye bigira hydrata reaction kugirango imbaraga zihuze nimbaraga zo kwikuramo ibintu.Kubwibyo, mubwubatsi bwubushyuhe bwo hejuru, kugirango tugere ku ngaruka zo gufata amazi, ibicuruzwa byiza bya HPMC bigomba kongerwaho muburyo buhagije ukurikije formulaire, bitabaye ibyo, hydrated idahagije, kugabanya imbaraga, guturika, gutobora no kugwa byatewe no gukama cyane bizabaho.Yongera kandi ingorane zo kubaka kubakozi.Mugihe ubushyuhe bugabanutse, ingano ya HPMC yongeweho irashobora kugabanuka buhoro buhoro, kandi ingaruka imwe yo gufata amazi irashobora kugerwaho.
