Uruhare rwa hydroxypropyl methyl selulose muri minisiteri

Hydroxypropyl methyl selulose muri minisiteri yumye, selile ya ether yongeyeho ni mike cyane, ariko irashobora kunoza cyane imikorere ya minisiteri itose, ubwubatsi bwa minisiteri nimwe mubyongeweho. Noneho, hydroxypropyl methyl selulose ikoreshwa mumashanyarazi yumye ya selireose ether ni hydroxypropyl methyl selulose ether (HPMC). Hydroxypropyl methyl selulose muri minisiteri yumye HPMC igira uruhare runini mu gufata amazi, kubyimba, kunoza imikorere yubwubatsi. Hydroxypropyl methylcellulose HPMC ntabwo yitabira imiti iyo ari yo yose, gusa igira uruhare runini. Ifu ya putty yongewemo amazi, kurukuta, ni reaction ya chimique, kuko hariho ibisekuru byibintu bishya, ifu ya putty kurukuta kumanuka kuva kurukuta, hasi ikabamo ifu, hanyuma bigakoreshwa, ntibikiriho, kuko byashizeho a ibikoresho bishya (calcium karubone). Ibice byingenzi bigize ifu ya calcium yumukara ni: Ca (OH) 2, CaO hamwe nuruvange ruto rwa CaCO3, CaO + H2O = Ca (OH) 2 - Ca (OH) 2 + CO2 = CaCO3 ↓ + H2O ivu rya calcium mumazi n'umwuka mubikorwa bya CO2, gushiraho karubone ya calcium, na HPMC gusa kubika amazi, ivu rya calcium ivu ifasha neza, ibyayo ntabwo byagize uruhare mubitekerezo.
 
Ubwiza bwa hydroxypropyl methyl selulose burashobora gukwirakwiza kimwe kandi neza mubisaka bya sima na pompe, hanyuma bigapakira ibice byose bikomeye, hanyuma bigakora urwego rwa firime itose, ubuhehere buri mukibanza igihe kirekire bukarekurwa buhoro buhoro, hamwe nubutaka bwa cimentitifique butagira imbaraga. , kugirango tumenye imbaraga zububiko nimbaraga zo kwikuramo ibikoresho. Kubwibyo, mubushyuhe bwo hejuru bwubaka icyi, kugirango ugere kubikorwa byo gufata amazi, ugomba kongeramo ibicuruzwa byiza bya HPMC ukurikije formulaire, bitabaye ibyo, hazaba byumye vuba kandi biterwa no kubura amazi adahagije, kugabanya imbaraga, guturika, ubusa ingoma no kugwa nibindi bibazo bifite ireme, ariko kandi byongera ingorane zo kubaka abakozi. Mugihe ubushyuhe bugabanutse, ubwinshi bwamazi yongewe na HPMC burashobora kugabanuka buhoro buhoro, kandi ingaruka zimwe zo gufata amazi zirashobora kugerwaho.
