Cawv ntawm HPMC viscosity thiab fineness ntawm cug cug kev ua haujlwm

Lub viscosity thiab fineness ntawm hydroxypropyl methylcelulose (HPMC) tuaj yeem cuam tshuam cov kev ua tau zoo ntawm cug. Ntawm no yog li cas txhua parameter tuaj yeem cuam tshuam yuav cuam tshuam kev cai:

1. Viscosity:
   • Dej khaws cia: Ntau hom viscosity HPMC cov qib nyiam khaws cov dej ntau dua hauv cov tshuaj khib sib xyaw. Cov dej ua kom huv no tuaj yeem txhim kho lub sijhawm ua haujlwm, txuas ntxiv qhib lub sijhawm, thiab txo qhov kev pheej hmoo ua kom qhuav, uas yog qhov tseem ceeb tshaj plaws hauv cov mob kub thiab qhuav.
   • Txhim kho Adhesion: HPMC nrog ntau dua Viscosity cov qauv ib thicker thiab ntau cohesive zaj duab xis nyob rau saum npoo ntawm cov nplaum ntawm cho kas, xws li aggregates thiab binders. Qhov no ua rau txoj kev txhim kho txoj hlua zog muaj zog thiab txo qhov kev pheej hmoo ntawm delamination.
   • Txo cov lus mos? Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv overhead los yog ntsug cov ntawv thov uas lub tshuaj tshuaj mic yuav tsum tswj hwm nws cov duab thiab ua raws li lub substrate.
   • Kev ua haujlwm tau zoo: HPMC nrog cov viscosity tsim nyog imparts xav tshuaj khib, tso cai rau kev sib xyaw ua ke, thiab siv. Nws txhim kho kev sib tsoo thiab coheseniveness ntawm cug tshuaj, ua kom yooj yim compolidation thiab xov.
   • Kev cuam tshuam rau cov ntsiab lus cua: tsis tshua muaj viscosity HPMC tuaj yeem tabkaum ntawm cov pa hluav taws xob, cuam tshuam nws khov-thaws tsis kam thiab kav ntev. Yog li ntawd, nws yog qhov tseem ceeb kom sib npaug viscosity nrog lwm cov khoom kom ntseeg tau cov cua cua zoo tshaj plaws.
2. Ke:
   • Particle dispersion: Finer hais ntawm HPMC zoo li tsis sib xws hauv lub tshuaj khib nyiab, ua rau kom txhim kho kev faib tawm thiab cov txiaj ntsig ntawm cov polymer thoob plaws. Qhov no ua rau muaj cov khoom ua tau zoo ib txwm muaj, xws li dej rov qab thiab cov nplaum.
   • Txo qhov kev pheej hmoo ntawm kev ua pob: Finer HPMC muaj cov khoom ntub zoo dua thiab muaj tsawg dua los tsim agglomerates lossis "pob" hauv clep sib tov. Qhov no txo ​​qhov kev pheej hmoo ntawm kev xa tawm tsis sib xws thiab ua kom muaj kev haus dej kom zoo thiab ua kom cov polymer.
   • Nto smellness: Finer HPMC hais pab txhawb rau Smoother Cug Chaw, txo txoj kev sib thooj ntawm cov npoo npoo npoo xws li pinholes lossis cov kab nrib pleb. Qhov no ua kom zoo ua rau lub ntsej muag zoo nkauj ntawm cov khoom tiav thiab txhim kho txhua qhov zoo.
   • Compatibility nrog lwm cov tshuaj ntxiv: Finer HPMC hais ntau dua nrog lwm cov tshuaj ntxiv siv hauv cov tshuaj xis, cov tshuaj xis, cov tshuaj ntsuab, thiab pigments. Qhov no tso cai rau kev sib haum xeeb thiab ua kom muaj homogeneity ntawm kev sib xyaw.

Hauv cov ntsiab lus, ob leeg viscosity thiab fineness ntawm HPMC ua si txoj haujlwm tseem ceeb hauv kev txiav txim cug kev ua haujlwm. Cov kev xaiv kom zoo thiab ua kom zoo dua ntawm cov tsis tuaj yeem ua rau kev txhim kho kev ua haujlwm, cov nplaum, sag tiv taus, thiab txhua yam zoo ntawm lub cug. Nws yog qhov tseem ceeb uas yuav tsum xav txog kev thov cov ntawv thov thiab cov xwm txheej thaum xaiv cov kab mob HPMC uas tsim nyog rau ib lub Cug Cug Cug.
