Hydroxypropyl methylcellulose ikoreshwa muburyo butandukanye bitewe nikirere

Ibintu nkubushyuhe bwikirere, ubushyuhe numuvuduko wumuyaga bizagira ingaruka kumuvuduko wimihindagurikire yubushyuhe muri sima ya sima nibicuruzwa bishingiye kuri gypsumu. Kubwibyo, mubihe bitandukanye, ingaruka zo gufata amazi zingana na HPMC ziratandukanye.

Mu bwubatsi bwihariye, ingaruka zo gufata amazi ya slurry zirashobora guhinduka mukwongera cyangwa kugabanya umubare wa HPMC wongeyeho. Kugumana amazi ya hydroxypropyl methyl selulose ether mugihe cyubushyuhe bwo hejuru nikimenyetso cyingenzi cyo gutandukanya ubwiza bwa hydroxypropyl methyl selulose ether. Ibicuruzwa byiza bya HPMC 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. Amatsinda ya mikorerexy na hydroxypropoxy akwirakwizwa neza murwego rwa selile ya selile, bishobora kuzamura ubushobozi bwa atome ya ogisijeni kuri hydroxyl na ether ihuza amazi kugirango ibe imiyoboro ya hydrogène, kugirango amazi yubusa ahinduke amazi aboshye, bityo bigenzurwe neza guhumeka kw'amazi guterwa n'ubushyuhe bwo hejuru, no kugera ku mazi menshi.
Cellulose yo mu rwego rwohejuru HPMC irashobora gukwirakwizwa kimwe kandi neza mugisima cya sima hamwe nibicuruzwa bishingiye kuri 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 bwubushyuhe, kugirango tugere ku ngaruka zo gufata amazi, ibicuruzwa byiza bya HPMC bigomba kongerwamo byinshi bihagije ukurikije formulaire, bitabaye ibyo, hydrated idahagije, kugabanya imbaraga, guturika, gutobora no kugwa byatewe no gukama cyane bizabaho. Byongera kandi ingorane zo kubaka kubakozi. Mugihe ubushyuhe bugabanutse, umubare wa HPMC wongeyeho urashobora kugabanuka buhoro buhoro, kandi ingaruka zimwe zo gufata amazi zirashobora kugerwaho.
