Tshuaj Qib HPMC
Tshuaj qib HPMCHydroxypropyl methylcellulose yog dawb los yog mis nyuj dawb, tsis muaj ntxhiab, tsis muaj saj, hmoov fibrous lossis granule, qhov hnyav poob thaum ziab tsis tshaj 10%, soluble hauv dej txias tab sis tsis yog dej kub, maj mam hauv dej kub o, peptization, thiab tsim cov kua colloidal viscous, uas dhau los ua cov kua thaum txias, thiab dhau los ua gel thaum cua sov. HPMC tsis yaj hauv ethanol, chloroform thiab ether. Nws yaj hauv cov kuab tshuaj sib xyaw ntawm methanol thiab methyl chloride. Nws kuj yaj hauv cov kuab tshuaj sib xyaw ntawm acetone, methyl chloride thiab isopropanol thiab qee cov kuab tshuaj organic. Nws cov kua aqueous tuaj yeem tiv taus ntsev (nws cov kua colloidal tsis raug rhuav tshem los ntawm ntsev), thiab pH ntawm 1% kua aqueous yog 6-8. Cov mis molecular ntawm HPMC yog C8H15O8-(C10H18O6)-C815O, thiab qhov hnyav molecular yog li 86,000.

Cov yam ntxwv thiab cov txiaj ntsig:
HPMC muaj cov dej zoo heev hauv dej txias. Nws tuaj yeem yaj rau hauv cov kua pob tshab nrog me ntsis do hauv dej txias. Ntawm qhov tsis sib xws, nws yeej tsis yaj hauv dej kub saum 60 degrees.℃thiab tsuas yog tuaj yeem o. Nws yog ib qho cellulose ether uas tsis yog ionic. Nws cov kua tsis muaj ionic them, tsis cuam tshuam nrog cov ntsev hlau lossis cov organic ionic, thiab tsis teb nrog lwm cov khoom siv raw thaum lub sijhawm npaj; nws muaj zog tiv thaiv kev rhiab heev, thiab raws li qib ntawm kev hloov pauv hauv cov qauv molecular nce ntxiv, nws yog qhov tiv taus kev ua xua thiab ruaj khov dua; nws kuj yog metabolically inert. Raws li ib tug kws tshuaj excipient, nws tsis metabolized lossis nqus. Yog li ntawd, nws tsis muab cua sov hauv cov tshuaj thiab cov khoom noj. Nws yog qis-calorie, tsis muaj ntsev, thiab tsis muaj ntsev rau cov neeg mob ntshav qab zib. Cov tshuaj allergenic thiab cov khoom noj muaj kev siv tshwj xeeb; nws yog qhov ruaj khov rau cov kua qaub thiab alkalis, tab sis yog tias tus nqi PH tshaj 2 ~ 11 thiab raug cuam tshuam los ntawm qhov kub siab dua lossis muaj lub sijhawm khaws cia ntev dua, nws viscosity yuav txo qis; nws cov kua dej tuaj yeem muab kev ua haujlwm nto, qhia txog qhov nruab nrab ntawm qhov nro thiab qhov sib txuas ntawm cov nqi; nws muaj kev ua haujlwm emulsification zoo hauv ob-theem systems, tuaj yeem siv ua tus stabilizer zoo thiab tiv thaiv colloid; Nws cov kua dej muaj cov khoom zoo heev rau kev tsim cov zaj duab xis, thiab yog cov ntsiav tshuaj thiab tshuaj ntsiav Ib qho khoom siv zoo txheej. Cov zaj duab xis txheej uas tsim los ntawm nws muaj qhov zoo ntawm kev tsis muaj xim thiab kev tawv. Ntxiv glycerin kuj tseem tuaj yeem txhim kho nws cov yas.
