Ethylcellulose muaj qhov ntom ntom ntom, uas ua rau nws lub teeb yuag. Cov cuab yeej no muaj txiaj ntsig zoo hauv cov ntawv thov uas qhov hnyav yog qhov tseem ceeb, xws li hauv kev tsim cov yeeb yaj kiab hnyav thiab txheej txheej.
8. Compatibility nrog lwm cov polymers:
Ethylcellulose yog sib xws nrog ntau hom polymers, tso cai rau kev sib xyaw ua ke nrog cov khoom siv kho mob. Qhov kev sib raug zoo no txuas ntxiv nws cov ntawv thov los ntawm kev tsim cov khoom siv hybrid nrog cov khoom zoo dua qub.
9. Tasteless thiab tsw tsw:
Ethylcellulose yog tasteless thiab odorless thiab yog haum rau siv nyob rau hauv lub chaw ua tshuaj thiab zaub mov industries qhov twg sensory yam tseem ceeb.
Kev siv ntawm ethylcellulose:
1. Pharmaceutical kev lag luam:
Tablet Txheej: Ethylcellulose feem ntau yog siv los ua cov txheej txheem rau cov ntsiav tshuaj. Zaj duab xis txheej muab kev tswj kev tso tawm, kev tiv thaiv los ntawm ib puag ncig yam, thiab txhim kho tus neeg mob ua raws.
Tswj kev tso tawm matrix: Ethylcellulose yog siv rau hauv kev tsim cov tshuaj tswj kev tso tawm matrix ntsiav tshuaj. Tswj kev tso tawm profiles tau tiav los ntawm kev kho cov thickness ntawm ethylcellulose txheej.
