Tshuaj Txhuam Hniav: Ua lub luag haujlwm ua kom tuab thiab ntub kom ntseeg tau tias cov khoom xyaw hauv cov mis sib xws.
3. Kev cia siab rau kev loj hlob
Nrog kev txhawb nqa cov tswv yim tiv thaiv ib puag ncig ntsuab thiab kev nthuav dav ntawm thaj chaw siv, qhov kev thov rau hydroxypropyl methylcellulose txuas ntxiv mus. Hauv kev lag luam kev tsim kho, HPMC, ua ib qho tseem ceeb ntawm cov khoom siv txuag hluav taws xob thiab cov khoom siv zoo rau ib puag ncig, muaj kev cia siab dav hauv kev lag luam; hauv cov teb ntawm kev kho mob thiab zaub mov, HPMC tau dhau los ua cov khoom xyaw tseem ceeb vim nws muaj kev nyab xeeb thiab kev hloov pauv tau yooj yim; hauv cov khoom siv tshuaj txhua hnub, nws cov kev ua tau zoo sib txawv muab cov peev xwm rau cov khoom lag luam tshiab dua.
Hydroxypropyl methylcellulosetau dhau los ua cov khoom siv tshuaj lom neeg tseem ceeb hauv ntau lub lag luam vim nws cov khoom zoo heev thiab kev siv dav. Yav tom ntej, nrog kev ua kom zoo dua ntawm cov txheej txheem tsim khoom thiab kev tshwm sim tas mus li ntawm cov kev thov tshiab, HPMC yuav ua pov thawj nws tus nqi tshwj xeeb hauv ntau qhov chaw.
