HydroxyPropyyl methylcellulose (HPMC)yog ib qho khoom siv tseem ceeb ntxiv. Nws daim ntawv thov nyob rau hauv Premixed cov luag hauj lwm ntau yam tseem ceeb, feem ntau hauv kev txhim kho kev ua haujlwm ntawm kev ua haujlwm cug, txhim kho kev ua haujlwm, thiab txuas ntxiv rau lub sijhawm tsim kho.
1. Txhim kho kev ua haujlwm ntawm cug
Kev ua haujlwm ntawm kev ua tiav ntawm cov kev ua tiav kev hais txog qhov ua haujlwm cug, suav nrog fundity, yas thiab adhesion. Kimacell® Khocc, raws li cov polymer compound, muaj cov khoom siv kom zoo. Tom qab tau ntxiv rau lub tshuaj khib, nws tuaj yeem ua kom zoo ua rau vortcosity ntawm cov tshuaj khib, ua kom muaj kev sib xyaw ua ke, yog li kev txhim kho kev tsim kho ntawm lub tshuaj khib. Tshwj xeeb, HPMC tuaj yeem ua rau lub tshuaj tshuaj xpas yooj yim rau thaum lub sijhawm ua haujlwm tsis zoo, thiab zam qhov kev tsim kho ntawm cov dej khib nyiab tshwm sim los ntawm kev tshuaj khib nyiab ntau.
2. Txhim kho cov nplaum ntawm cug
Hauv kev tsim kho tej yaam num, cov nplaum ntawm cug yog ib qho ntawm cov yuam sij kom ntseeg tau tias qhov ruaj khov ntawm lub tsev. HPMC tuaj yeem tsim cov nplaum muaj zog ntawm cug thiab substrate los ntawm kev nce viscosity ntawm cug. Cov nplaum ua kom zoo nkauj tsis tsuas yog ua kom lub zog sib xyaw ua ke nrog cov khoom sib txuas ntawm phab ntsa thiab cov cib, tab sis kuj tseem muaj kev ruaj khov thiab ruaj khov ntawm phab ntsa.
3. Tswj cov dej noo kom muaj sia
HPMC muaj lub zog ua kom muaj zog. Nyob rau hauv premixed, ya raws yog ib qho tseem ceeb cuam tshuam rau kev ua tau zoo ntawm cug. Yog tias cov dej noo evaporates dhau nrawm, qhov ziab nrawm ntawm lub cug tshuaj yuav nrawm, ua rau muaj kev txo qis ntawm nws cov kev ua tau zoo thiab txawm tawg. HPMC muaj peev xwm ncua kev ncua ntawm cov dej noo thiab tswj kom noo noo hauv cov tshuaj khib, yog li ua kom muaj zog txaus thiab ua kom tiav lub zog zoo tshaj plaws thiab kav ntev.
4. Ncua lub sijhawm tsim kho
Vim tias nws feem ntau siv sijhawm ntev los ua cov txheej txheem xws li smearing thiab plastering thaum kev tsim kho, txuas ntxiv ntawm lub sijhawm tsim kho yuav tsum tau ua tshuaj khib. Qhov kev sib txuas ntawm HPMC tuaj yeem ncua kev ncua lub sijhawm tshuaj khib, tso cai rau cov neeg ua haujlwm tsim kho kom muaj sijhawm ntau los ua haujlwm. Tshwj xeeb tshaj yog nyob rau hauv kev tsim kho ntawm thaj chaw loj, txuas ntxiv lub sijhawm qhib kev ua haujlwm tau sai dhau lawm, thiab txo cov teeb meem ntawm collche agglomeration lossis tsis sib xws nyob rau hauv cov txheej txheem kev tsim kho.
5. Txhim Kho Cov Dej Tsis Txaus thiab Tshaj Tawm
Lwm txoj haujlwm tseem ceeb ua si los ntawm HPMC hauv kev tshuaj khib nyiab yog txhawm rau txhim kho cov dej tsis kam thiab khov rau ntawm cov tshuaj khib. Vim nws cov qauv tshwj xeeb, HPMC tuaj yeem tsim zaj duab xis tiv nrog muaj zog hydrophilicity nyob rau hauv lub cug, txhim kho lub cug lub peev xwm tiv thaiv dej nkag. Qhov no yog qhov tshwj xeeb tshaj yog rau cov khoom lag luam xws li kev siv hluav taws xob hluav taws xob thiab sab nrauv phab ntsa chot thaiv thiab sab nrauv lub neej ntawm lub tsev. Ib qho ntxiv, kev sib ntxiv ntawm HPMC kuj tseem tuaj yeem txhim kho lub zog ntawm cov kev tsim kho hauv thaj chaw txias, uas tuaj yeem zam kom tsis txhob khov-thaws kev puas tsuaj los ntawm qhov chaw kub tsawg.
6. Txhim kho cov kev hloov kho ntawm cov tshuaj khib
Tej yam tsim sib txawv ib puag ncig chaw tsim qauv thiab kev tsim cov kev tsim kho muaj cov sib txawv uas yuav tsum muaj kev sib xyaw ntawm colled. HPMC tuaj yeem hloov kho cov khoom sib txawv, xws li fundicity, viscosity thiab ntau hom tshuaj khib tau ua kom tau raws li qhov kev tsim kho cov haujlwm sib txawv. Piv txwv, rau sab nrauv phab ntsa rwb thaiv tsev rwb thaiv tsev, siab dua thiab dej tsis kam; Thaum lub sij hawm rau pobzeb cov nplaum, ntau dua cov xim yuav tau them rau nws qhov kev sib luag thiab fellity. HPMC tuaj yeem kho cov kev ua tau zoo ntawm cug raws li cov kev sib txawv no kom tau muab cov tshuaj tsim nyog tshaj plaws.
7. Txhim kho cov nplaim hluav taws xob cug
HPMC tsis tuaj yeem txhim kho kev tsim kho ntawm cug, tab sis kuj txhim kho lub tiaj huv thiab ua tiav ntawm cug sab. Thaum lub sij hawm tsim kho cov nyhuv ntawm Kimacell®hpmc tuaj yeem ua rau cov teeb meem me me, thiab ua kom pom tseeb tom qab kev tsim kho zoo nkauj dua. Tshwj xeeb tshaj yog nyob rau hauv qee qhov kev kho kom zoo nkauj nrog cov phiaj xwm theem siab, cov nyhuv ntawm cov nplaum thiab cov vuas tom qab, cov vuas, thiab lwm yam.
Raws li ib qho tseem ceeb ntxiv rau hauv cov tshuaj khib ua ntej,HPMCplays ntau-faceted lub luag haujlwm. Los ntawm kev txhim kho kev ua haujlwm cug, txhim kho cov dej khov, kom txhim kho cov npoo av, txhim kho cov dej sib xyaw, txhim kho cov tshuaj tua kab cug, nws txoj haujlwm hauv kev txhim kho cov tshuaj cug kev ua tau tsis tuaj yeem tsis quav ntsej. Raws li kev tsim kho cov kev tsim kho cov kev cai ua haujlwm txuas ntxiv ntxiv, kev siv HPMC txuas ntxiv txuas ntxiv thiab muab cov khoom siv zoo dua thiab txhim khu kev qha cov khoom siv uas zoo dua rau kev tsim kho.
