3. Kev ruaj ntseg ntawm hydroxypropyl methylcellose
Tau muaj ntau txoj kev tshuaj xyuas los ntawm kev tshawb fawb thiab cov koom haum tswj hwm ntawm kev nyab xeeb ntawm HPMC. HPMC yog dav tau txiav txim siab tau muaj kev nyab xeeb thiab muaj cov zoo biocompatibility. Nws tsis yog nqus tau los ntawm tib neeg lub cev thiab tsis yauv hloov cov tshuaj hauv lub cev, tab sis yog tawm los ntawm kev zom zaub mov raws li kev noj fiber ntau.
