Hydroxypropyl Methylcellulose
HydroxypropylMethylcellulose (HPMC) ama hypromellosewaa derivatives ee methyl cellulose ethers. Waafibros cad ama ka baxsan cad ama granularether cellulosebudo. Hadda waa cellulose ethers oo leh waxqabadka ugu wanaagsan adduunka, isku-darka dhumucda, laalidda, firdhinta, emulsifying iyo xasilinta. Hydroxypropyl methyl cellulose (HPMC) ma aha sun, fududahay in la isticmaalo, oo si fudud biyaha ugu milmaan. Waa polyanion oo ku jira xal aqueous ah waxayna leedahay sifooyin jireed oo gaar ah. Waxqabadka gaarka ah waa sida hoose:

Astaamaha:
1. Solubility: Waxay ku dhowdahay inaan lagu milmi karin ethanol, ether iyo acetone, waxayna ku milmaysaa xal kolloidal ah oo cad ama waxoogaa turbid ah oo biyo qabow ah. Waxaa lagu milmi karaa qaar ka mid ah dareerayaasha organic, sidoo kale waxaa lagu milmi karaa dareere isku dhafan oo biyo-organic ah.
2. Cusbada iska caabbinta: Waxay ku xasilloon tahay xalalka aqueous marka cusbada birta ah ama electrolytes organic ay joogaan.
3. Dhaqdhaqaaqa dusha sare: waxa loo isticmaali karaa sida ilaalinta kolloid, emulsifier iyo kala firdhiye.
4. PH-dejinta: Qiimaha PH waa mid xasiloon inta u dhaxaysa 3.0 ~ 11.0. Viscosity ee xalka aqueous si dhib leh uma saameeyo aashitada ama alkali.
