Vim li cas cov viscosity ntawm cov neeg hais ua cellulose tseem ceeb?

Cov cellulose Cov chav kawm yog ib qho tseem ceeb ntawm cov dej-soluble polymers uas tau siv dav hauv kev tsim kho, cov tshuaj, khoom noj, cov tshuaj pleev ib ce thiab lwm thaj teb. Lub viscosity ntawm cellulose of cellulose of cellulose of cellulose ntawm cov ntsuas tseem ceeb ntawm nws cov kev ua tau zoo, uas cuam tshuam nws daim ntawv thov kev cuam tshuam thiab kev siv.

1. Cov nyhuv ntawm viscosity ntawm kev daws teeb meem
Tom qab cellulose ether yog yaj hauv dej, nws yuav ua rau muaj qee yam viscosity, uas tuaj yeem txhim kho qhov ruaj khov ntawm txoj kev daws teeb meem. Cov kev daws teeb meem siab tau voscority tuaj yeem tiv thaiv kev tawm tsam thiab delamination ntawm cov ntaub ntawv ntawm cov tsev, xws li cov ntaub ntawv cement thiab gypsum. Lub viscosity ntawm cellulose ntawm cellulose ntawm cellulose tuaj yeem txhim kho qhov ruaj khov ntawm cov sib tov thiab ua kom paub meej tias cov khoom sib thooj thiab sib xws.

2. Cov nyhuv ntawm viscosity ntawm Rheological Khoom
Viscosity yog ib qho tseem ceeb cuam tshuam rau kev thaj chaw rheological ntawm cellulose ether. Cov qauv kev thov sib txawv muaj cov sib txawv rau cov khoom siv rheological. Piv txwv li, hauv cov kev ua kom muaj kev hais ua cellulose yuav tsum tau muab cov khoom siv hluav taws xob tsim nyog kom ntseeg tau tias cov txheej txheem muaj cov teeb pom kev zoo thiab du; Thaum nyob rau hauv lub chaw muag tshuaj, ntim ntawm tsiav tshuaj thiab cov ntsiav tshuaj txheej txheej txheej txheem txheej txheem ntawm cov cellulose muaj neeg muaj kev pab kom ntseeg tau thiab ruaj khov. Yog li ntawd, los ntawm kev kho lub viscosity ntawm cellulose cov neeg pab neeg hauv cellu, nws cov khoom siv rheological tuaj yeem ua tau zoo rau hauv cov ntawv thov sib txawv.

3. Cov nyhuv ntawm viscosity ntawm thickening nyhuv
Lub viscosity ntawm cellulose ether ncaj qha txiav txim nws cov nyhuv tuab. Lub luag haujlwm ntawm cov thickeners yog qhov tseem ceeb heev hauv ntau cov khoom. Piv txwv li, hauv cov khoom noj, kev siv cov thickeners tuaj yeem cuam tshuam lub saj thiab ruaj khov ntawm cov khoom; Hauv cov tshuaj pleev ib ce, cov thickeners tuaj yeem kho cov qauv thiab fellity ntawm cov khoom. Los ntawm nce lub viscosity ntawm kev daws teeb meem, cellulose muaj kev hais ua kom cov khoom lag luam tau zoo ib yam, yog li kev txhim kho cov khoom siv kev paub thiab kev ua haujlwm.

4. Cov nyhuv ntawm viscosity ntawm cov khoom nplaum
Hauv qee cov ntawv thov, lub viscosity ntawm cellulose cov neeg muaj neeg muaj kev hais kom muaj kev cuam tshuam nrog lawv cov khoom nplaum. Piv txwv li, hauv cov nplais mastics thiab phab ntsa putries, lub viscosity ntawm cov neeg hais ua cellulose cuam tshuam rau lawv cov nplaum rau lub substrate. Tus viscosity kom zoo tuaj yeem txhim kho cov khoom siv nplaum thiab txhim kho nws txoj kev tiv thaiv kom tsis txhob poob thiab tawg. Qhov no yog qhov tseem ceeb kom paub meej qhov zoo thiab kav siv tau kev tsim kho.

5. Teeb meem thiab cov nyom ntawm viscosity tswj
Lub viscosity tswj ether yog qhov kev ua haujlwm nyuaj heev vim hais tias qhov mob ntawm cellulose xws li tsis tshua muaj qhov kub thiab txias, pH nqi concentration thiab lwm yam. Yog li ntawd, yuav ua li cas kom tswj tau lub viscosity ntawm cellulose kev siv tshuaj lom neeg los ntawm kev cai ntawm cov ntawv thov cov ntaub ntawv tseem ceeb hauv kev tshawb fawb thiab kev siv cov ntawv thov.

Lub viscosity ntawm cellulose neeg hais ua yog qhov tseem ceeb rau lawv cov ntawv thov hauv ntau daim teb. Nws tsis yog cuam tshuam rau qhov ruaj khov, rheatoral cov khoom siv thiab thickening cov nyhuv cuam tshuam nrog cov khoom nplaum thiab cov nyhuv kawg ntawm cov khoom lag luam. Yog li ntawd, thaum xaiv thiab siv cov cellulose muaj kev pab cuam cellulose, lawv cov yam ntxwv viscosity yuav tsum tau txiav txim siab los xyuas cov khoom lag luam zoo thiab ua tau zoo. Yav tom ntej, nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev hloov pauv cov ntawv thov, cov kev tshawb fawb thiab kev tswj hwm ntawm cov kev tshawb nrhiav tau txuas ntxiv.
