Dab tsi yog qhov tsim nyog viscosity ntawm hydroxypropyf methylcellose (HPMC)?

1. Lub tsev ua haujlwm
Hauv cov ntaub ntawv hauv tsev, HPMC feem ntau yog siv nyob rau hauv cov chaw ua haujlwm lossis cov khoom siv tshuaj khib nyiab, xws li cov khoom siv viscesive, txheej, thiab lwm yam khoom lag luam zoo:

Putty Hmoov: Feem ntau xaiv 50,000-100,000 tus MPaSix puas tuaj yeem txhim kho kev ua haujlwm thiab siv kom muaj dej khaws cia.
Pobzeb nplaum: HPMC nrog 75,000-100,000 Mpa-· S tau siv los txhim kho adhesion thiab anti-diab ntawm cov khoom.
Kev ua tus kheej txoj kab sib nraus: feem ntau xaiv viscosposity qis, xws li 400-4,000 tus Mpoos ntawm cov sib tov sib xyaw thiab txhim kho kev sib xyaw.

2. Tshuaj thiab Khoom Noj
HPMC yog tsuas yog siv raws li thickener, emulsifier, capsule plhaub cov ntaub ntawv, thiab lwm yam. Cov kev siv sib txawv yuav tsum muaj viscosities txawv:

Tshuaj Ntsiav Tshuaj Ntsiav Tshuaj Plhaub: 3,000-5,600 mpa-· s siv los xyuas kom muaj kev ua yeeb yam thiab lub sijhawm tsis sib xws ntawm cov tshuaj ntsiav.

Cov ntsiav tshuaj-tso tawm: 15,000-100,000 tus MPA puas yog siv cov khoom tawv pob txha los tswj cov tshuaj tso tawm tshuaj.

Cov Khoom Noj Ntxiv: Tsis muaj viscosity HPMC (xws li 100-5,000 tus lej MpAPN nkaus) yog feem ntau siv los thicken thiab ruaj khov cov khoom noj.

3. Cov tshuaj tiv thaiv thiab inks
HPMC tuaj yeem siv los ua cov tuab hauv cov dej ua haujlwm thiab cov cwj mem los txhim kho cov txheej ruaj thiab txhuam hniav:

Cov dej pleev dej ua haujlwm: 5,000-40,000 mpa-· s tau raug xaiv los txhim kho rheology thiab los tiv thaiv cov khoom lag luam.
Number case: cov khoom viscosity qis (400-5,000 mpa · s yuav muaj ntau dua los xyuas kom muaj kev sib cais thiab kev sib cais ua ke.

4. Cov khoom lag luam txhua hnub
HPMC tsuas yog siv rau thickening thiab ruaj khov emulsified lub tshuab hauv cov khoom lag luam txhua hnub xws li cov khoom noj tshuaj thiab cov khoom siv saib xyuas cov tawv nqaij:

Zawv plaub hau thiab da dej gel: 1,000-10,000 leej Mpa-ill feem ntau siv los xyuas kom ntseeg tau tias cov khoom siv hluav taws xob tsim nyog.
Daim tawv nqaij cream: lub viscosity ntau feem ntau yog 10,000-75,000 tus MPA, uas pab txhim kho daim ntawv thov kom zoo nkauj thiab noo noo.
Lus hauv Viscosity Xaiv
Lub viscos ntawm HPMC cuam tshuam los ntawm qhov kub thiab xav tau kho kom haum raws li kev siv ib puag ncig.
Qhov ntau dua cov viscosity, lub sijhawm ntev dua, yog li siab viscosity HPMC feem ntau yuav tsum tau yaj ua ntej lossis ua kom zoo.
Hauv cov ntawv thov tshwj xeeb, nws raug pom zoo kom ua cov kev sim me me kom pom cov vircosity feem ntau.

Lub viscosity ntawm HPMC yuav tsum txiav txim siab raws li cov ntawv thov tiag tiag. Feem ntau hais lus:
Tsis muaj viscosity (400-5,000 tus mpa ·
Nruab nrab viscosity (5,000-75,000 mpa75,000 mpais ·
Cov viscosity siab (75,000-100,000 + Mpa-Mpa-mils, thiab kev tshaj tawm-tso cov tshuaj uas yuav tsum muaj adhesion ntau dua thiab ua yeeb yaj kiab ntau dua thiab ua yeeb yaj kiab.
Thaum xaiv cov viscc, nws raug nquahu kom muab cov kev xav tau tshwj xeeb, tsim cov txheej txheem thiab cov txheej txheem txheej txheem kom ntseeg tau tias kev ua tau zoo tshaj plaws.
