Muri sima, na centrive na gypsum bashingiye kuri gypsum, hydroxyPropyl methylcellse cyane cyane igira uruhare mu kugumana amazi no kubyimba, kandi birashobora kunoza neza ibihano na sag kurwanya ibitotsi.
Ibintu nkubushyuhe bwikirere, ubushyuhe hamwe numuvuduko wumuvuduko wumuyaga bizagira ingaruka kumibare y'amaraso muri sima na parpsum. Kubwibyo, mubihe bitandukanye, hari itandukaniro ryingaruka zo kugumana amazi hamwe na hydroxypropyl methylcellse yongeyeho. Mubwubatsi bwihariye, ingaruka zo kugumana amazi zirashobora guhindurwa no kwiyongera cyangwa kugabanya umubare wa HPMC yongeyeho. Kugumana amazi munsi yubushyuhe bwinshi nicyo kimenyetso cyingenzi kugirango utandukane ubwiza bwa hydroxyproppopyl methylcellse ether.
Ibicuruzwa byiza bya hydroxypropyl methylcellse Ibicuruzwa bikurikiranye birashobora gukemura ikibazo cyo kugumana amazi munsi yubushyuhe bwinshi. Mubihe byubushyuhe bwinshi, cyane cyane mubice bishyushye kandi byumye kandi byubatse byubwubatsi bwizuba, HPMC yo hejuru ya HPMC isabwa kunoza ubushake bwo kugumana amazi. Ubuziranenge bwa HPMC ifite uburinganire bwiza cyane. Uburyo bwamatsinda ya HydroxyPropy na HydroxyPropoplex yagabanijwe neza kuruhande rwa molekile, bishobora kunoza ubushobozi bwa atome ya ogisijeni kuri hydroxyl na ethers ingoma yo kwiteranya namazi kugirango ikore hydrogen. , kugirango amazi yubuntu ahinduke amazi meza, kugirango agenzure neza imyanya y'amazi iterwa n'ubushyuhe bwo hejuru, kandi igahagarikwa amazi menshi.
HydroxyPropyl Methylcellellse irashobora gutatana neza kandi neza kandi bishingiye ku bicuruzwa bishingiye kuri site na fagitire, kandi bigize filime ihamye, kandi ubushuhe busekeje buhoro buhoro, kandi burya Hydration Reaction hamwe nibikoresho bya selling inorungo kugirango byemeze imbaraga nimbaraga zimishange yibikoresho.
Kubwibyo, mubushyuhe bwizuba, kugirango tugere ku ngaruka zo kugumana amazi, birakenewe kongeramo ibicuruzwa byiza bya HPMC muburyo buhagije ukurikije formulaire ihagije ukurikije formulaire ihagije ukurikije formulaire ihagije ukurikije formulaire ihagije ukurikije formulaire ihagije ukurikije formulaire ihagije ukurikije formulaire, bitabaye ibyo, kugabanya imbaraga, guca imbaraga, kunyeganyega no kumena guterwa cyane. ibibazo, ariko kandi byongera ingorane zububiko. Mugihe ubushyuhe bugabanuka, umubare wa HPMC wongeyeho urashobora kugabanuka buhoro buhoro, kandi ingaruka zimwe zo kugumana amazi zirashobora kugerwaho.
