Siab viscosity 200000 HPMC

Hydroxypropyl Methylcellulose (HPMC)yog ib qho cellulose ether uas tsis yog ionic siv dav hauv kev tsim kho, tshuaj, khoom noj, tshuaj lom neeg txhua hnub thiab lwm yam lag luam. Raws li nws cov viscosity, HPMC tuaj yeem muab faib ua cov qib viscosity qis, viscosity nruab nrab thiab viscosity siab. Ntawm lawv, HPMC nrog viscosity ntawm 200000 mPa · s yog cov qib viscosity siab, muaj kev sib xws zoo heev, ua zaj duab xis thiab khaws dej, thiab muaj txiaj ntsig zoo rau kev siv hauv ntau qhov chaw.

1. Cov yam ntxwv tseem ceeb

HPMC viscosity siab (200000 mPa · s) yog ua los ntawm cov polymer cellulose ntuj thiab hloov kho los ntawm etherification. Nws cov tsos feem ntau yog dawb lossis off-white hmoov nrog zoo fluidity thiab yooj yim dispersibility. Hom HPMC no tuaj yeem dispersed sai sai hauv dej txias los ua cov kua pob tshab lossis translucent viscous. Nws cov nqi viscosity yog hais txog dynamic viscosity ntsuas hauv 2% aqueous kua ntawm 20 ° C, ncav cuag 200000 mPa · s, qhia txog kev sib xws siab heev thiab rheological zog.

2. Kev ua tau zoo tshaj plaws

Kev khaws cia dej zoo heev

HPMC viscosity siab muaj zog nqus dej thiab khaws dej tau zoo, tshwj xeeb tshaj yog hauv cov ntaub ntawv tsim kho, nws tuaj yeem tiv thaiv dej kom tsis txhob evaporate sai dhau, thiab zam kev tawg thiab lub zog poob los ntawm kev poob dej.

Thickening thiab lubricity

HPMC nrog qib viscosity ntawm 200000 muaj cov nyhuv thickening tseem ceeb, thiab txawm tias qhov ntxiv tsawg, nws tuaj yeem ua rau kom viscosity ntawm cov tshuaj lossis lub kaw lus nce ntxiv. Tib lub sijhawm, nws muaj cov roj nplua nyeem zoo thiab cov khoom siv tsim kho, ua rau cov xim, putty thiab mortar du thiab yooj yim dua rau kev khiav lag luam thaum lub sijhawm tsim kho.

Cov khoom zoo uas ua rau zaj duab xis zoo

Hom HPMC no tuaj yeem tsim cov zaj duab xis tawv, yoog tau thiab pob tshab tom qab ziab, uas pab txhim kho kev hnav tsis kam thiab kev nplaum ntawm cov txheej.

Kev ruaj khov tshuaj lom neeg muaj zog

HPMC yog cov polymer uas tsis yog ionic, uas ruaj khov rau cov kua qaub thiab alkalis thiab tsis yooj yim rau kev cuam tshuam nrog lwm cov khoom siv tshuaj lom neeg, uas ua rau nws muaj kev sib raug zoo hauv cov qauv nyuaj.

3. Daim ntawv thov

Kev lag luam tsim kho

HPMC viscosity siab yog siv dav hauv cov ntaub ntawv tsim kho xws li cov mortar qhuav, cov nplaum pobzeb, cov mortar thermal insulation, hmoov putty, thiab lwm yam. Nws cov haujlwm thickening thiab dej khaws cia tuaj yeem txhim kho kev ua haujlwm ntawm kev tsim kho, txhim kho kev nplaum thiab cov khoom tiv thaiv kev plam.

Kev lag luam tshuaj

Ua ib qho tshuaj tswj kev tso tawm matrix thiab cov khoom siv plhaub capsule, cov viscosity siab HPMC tuaj yeem siv ua cov khoom tseem ceeb ntawm kev npaj tso tawm mus tas li kom ntev lub sijhawm tso tawm tshuaj thiab txhim kho bioavailability.

Kev lag luam zaub mov

Siv ua cov emulsifier, stabilizer, suspending agent thiab thickener hauv cov khoom noj, xws li cov khoom noj uas muaj roj tsawg thiab cov khoom ci kom txhim kho cov qauv thiab saj.

Kev tshuaj lom neeg txhua hnub

HPMC siv ua cov khoom ua kom tuab thiab ruaj khov hauv tshuaj zawv plaub hau, tshuaj ntxuav ntsej muag, thiab tshuaj pleev kom txhim kho cov khoom zoo nkauj thiab xav.

4. Kev siv thiab kev ceev faj

Thaum siv HPMC uas muaj viscosity siab, nws yuav tsum tau maj mam ntxiv rau hauv dej ntawm chav tsev kub thiab dispersed thaum do kom tsis txhob agglomeration. Tom qab lub dispersion system tau tsim nyob rau theem pib, nws yuav tsum tau tso rau sawv ntsug rau tag nrho hydration kom thaum kawg tsim cov kua nplaum thiab pob tshab. HPMC yuav tsum tsis txhob sib xyaw nrog cov kua qaub thiab alkalis muaj zog kom tiv thaiv nws cov qauv molecular los ntawm kev puas tsuaj. Tsis tas li ntawd, qhov chaw cia khoom yuav tsum tsis txhob muaj av noo thiab kub siab kom tiv thaiv cov khoom los ntawm agglomerating vim av noo thiab cuam tshuam rau kev ua haujlwm.

Siab viscosity 200000 HPMCtau dhau los ua cov khoom siv tseem ceeb hauv ntau lub lag luam vim nws qhov kev ua tau zoo heev thiab kev hloov pauv tau hauv ntau qhov chaw. Nrog kev nce qib ntawm thev naus laus zis thiab kev nthuav dav ntawm kev thov ua lag luam, nws qhov kev siv yuav raug nthuav dav ntxiv. Kev paub txog nws cov yam ntxwv kev ua tau zoo thiab cov txheej txheem siv kom raug yuav ua rau nws muaj txiaj ntsig zoo dua thiab txhim kho cov khoom zoo thiab kev ua haujlwm ntau lawm.
