Qhov kev faib ua feem ntawm HPMC ntxiv rau hauv cov txheej txheem ntawm kev tsim cov tshuaj ntxhua khaub ncaws yog qhov tsim nyog tshaj plaws
Thaum nws los txog rau kev tsim cov tshuaj ntxhua khaub ncaws, muaj ntau yam uas yuav tsum tau xav txog txhawm rau tsim cov khoom zoo tshaj plaws.Ib qho tseem ceeb tshaj plaws ntawm cov no yog qhov feem ntawm HPMC (hydroxypropyl methylcellulose) uas tau ntxiv rau cov tshuaj ntxuav tes thaum lub sijhawm tsim khoom.HPMC yog ib qho tseem ceeb muaj nyob rau hauv uas yuav pab kom tuab thiab stabilize lub xab npum, thiab nws yog ib qho tseem ceeb kom tau raws li qhov kev faib ua feem kom thiaj li ua tau zoo tshaj plaws.
Yog li dab tsi yog qhov zoo tshaj plaws ntawm HPMC ntxiv rau cov ntxhua khaub ncaws?Qhov no yuav nyob ntawm ntau yam, suav nrog hom tshuaj ntxuav tes uas raug tsim thiab siv cov khoom siv.Txawm li cas los xij, feem ntau, nws raug pom zoo tias qhov kev faib ua feem ntawm HPMC yuav tsum khaws cia ntawm 0.5% thiab 2% ntawm tag nrho qhov hnyav ntawm cov tshuaj ntxuav tes.
Ntxiv HPMC ntau dhau rau cov tshuaj ntxuav tes tuaj yeem ua rau cov khoom ua kom tuab heev thiab nyuaj rau nchuav lossis siv tau zoo.Ntawm qhov tod tes, tsis ntxiv HPMC txaus tuaj yeem ua rau cov tshuaj ntxuav tes nyias nyias thiab tsis ruaj khov, uas tuaj yeem txo nws cov txiaj ntsig ntawm kev ntxuav khaub ncaws.
Lwm qhov kev xav tseem ceeb thaum nws los txog rau feem ntawm HPMC hauv cov ntxhua khaub ncaws ntxhua khaub ncaws yog hom HPMC siv.Ntau hom HPMC yuav muaj cov khoom sib txawv, thiab qee qhov yuav tsim nyog rau qee hom tshuaj ntxhua khaub ncaws ntau dua li lwm tus.Vim li no, nws yog ib qho tseem ceeb uas yuav tau ua tib zoo xav txog cov khoom ntawm txhua hom HPMC thiab xaiv qhov uas zoo tshaj plaws rau kev siv cov tshuaj ntxuav tes.
qhov kev faib ua feem ntawm HPMC ntxiv rau hauv cov txheej txheem ntawm kev tsim cov ntxhua khaub ncaws ntxhua khaub ncaws yog qhov tseem ceeb rau kev ua tau zoo thiab kev ua tau zoo ntawm cov khoom kawg.Los ntawm kev ua tib zoo xaiv qhov kev faib ua feem tsim nyog ntawm HPMC thiab xaiv hom HPMC rau txoj haujlwm, cov tuam ntxhab tuaj yeem xyuas kom meej tias lawv cov tshuaj ntxuav tau zoo tshaj plaws thiab muab cov txiaj ntsig zoo rau cov neeg siv khoom.
