Awoodda haynta biyaha ee hydroxypropyl methylcellulose waxay kuxirantahay nuxurka hydroxypropyl. Isla shuruudo la mid ah, awoodda haynta biyaha ee hydroxypropyl methylcellulose sare waa ka sii xoog badan tahay, iyo maadada methoxy ee ka kooban hydroxypropyl isku mid ah ayaa si habboon loo dhimay. . Markasta oo ay sareeyso maadada hydroxypropyl methylcellulose, way sii weynaanaysaa mawqifkeeda, marka marka aad dooranayso badeecad, waa in aad doorataa badeecada adiga kugu habboon iyada oo loo eegayo ujeedada alaabta.
Heerkulka iyo arrimo kale ayaa saameyn ku leh haynta biyaha ee hydroxypropyl methylcellulose.
Heerkulka jelka kulaylka:
Cellulose ether HPMC waxay leedahay heerkulka gelation kulaylka sare iyo haynta biyaha wanaagsan; taa lidkeeda, waxay leedahay haynta biyaha oo liidata.
Viscosity of cellulose ether HPMC:
Marka viscosity ee HPMC kordho, haynta biyaha sidoo kale kordhisaa; marka viscosity-ku kordho ilaa xad, korodhka xajinta biyaha ayaa hoos u dhacaya.
Cellulose ether HPMC isku mid ah:
HPMC waxay leedahay falcelin isku mid ah, qaybinta isku midka ah ee methoxyl iyo hydroxypropoxyl, waxayna leedahay biyo celin wanaagsan.
Cellulose ether qiyaasta HPMC:
Inta badan qiyaasta, ayaa sare u kaca heerka haynta biyaha iyo sida badan oo cad saamaynta sii haysashada biyaha.
Marka qadarka dheeriga ah uu yahay 0.25 ~ 0.6%, heerka haynta biyaha ayaa si degdeg ah u kordheysa iyadoo la kordhinayo qadarka dheeriga ah; marka qadarka dheeriga ah uu sii kordho, isbeddelka korodhka ee xajinta biyaha ayaa hoos u dhacaya.
Marka la soo koobo, haynta biyaha ee HPMC waxay la xiriirtaa arrimo ay ka mid yihiin heerkulka iyo viscosity, haynta biyuhu waxay la xiriirtaa qaddarka hydroxypropyl methylcellulose ee lagu daray. Marka qadarka hydroxypropyl methylcellulose uu gaaro qiimo gaar ah, waxqabadkeeda haynta biyaha waxay gaartaa dheelitirnaan.
