Viscosity yog qhov tseem ceeb hauv kev lag luam cellulose, cuam tshuam rau kev ua haujlwm thiab cov yam ntxwv ntawm cov khoom siv cellulose.Ob txoj kev siv los ntsuas viscosity yog Brookfield Viscosity thiab Viscosity NDJ 2% tov.Tsab ntawv xov xwm no yog txhawm rau tshawb nrhiav qhov sib txawv ntawm ob txoj kev ntsuas viscosity, ua kom pom kev ntawm lawv lub luag haujlwm hauv kev ntsuas cellulose ethers thiab lawv cov kev siv hauv kev lag luam cellulose.
Brookfield Viscosity:
Brookfield Viscosity yog ib txoj kev siv dav los ntsuas qhov tsis kam ntawm cov kua dej ntws.Nws suav nrog kev siv Brookfield Viscometer, lub viscometer rotational, los txiav txim siab viscosity ntawm tus qauv.Cov cuab yeej ntsuas lub torque yuav tsum tau tig ib spindle rau hauv cov kua dej ntawm qhov ceev tsis tu ncua.Tom qab ntawd lub viscosity yog xam raws li kev nyeem ntawv torque.
Viscosity NDJ 2% Kev daws:
Viscosity NDJ 2% tov yog hais txog kev ntsuas viscosity ntawm 2% tov ntawm cellulose ether.Nws yog ua los ntawm NDJ-1 viscometer, uas siv lub pob poob.Nyob rau hauv txoj kev no, lub pob calibrated tau tso cai kom poob ywj siab los ntawm 2% cellulose ether tov, thiab lub sij hawm siv rau lub pob kom dhau qhov kev ncua deb yog ntsuas.Lub viscosity ntawm cov tshuaj yog txiav txim siab raws li lub sij hawm poob ntawm lub pob.
Qhov sib txawv ntawm Brookfield Viscosity thiab Viscosity NDJ 2% Kev daws:
Measurement Principple: Qhov txawv ntawm ob txoj hauv kev yog nyob rau hauv lawv cov qauv ntsuas.Brookfield Viscosity yog raws li kev sib hloov viscometry, ntsuas lub torque xav tau rau spindle rotation, thaum Viscosity NDJ 2% Kev daws yog nyob ntawm txoj kev poob pob los txiav txim siab viscosity.
Concentration: Brookfield Viscosity tsis qhia meej qhov concentration ntawm cellulose ether tov yog ntsuas, raws li nws yuav siv tau rau ntau yam concentrations.Hauv qhov sib piv, Viscosity NDJ 2% Kev daws yog tshwj xeeb rau 2% concentration, muab cov qauv ntsuas rau cellulose ethers ntawm qhov tshwj xeeb no.
Kev siv tau: Brookfield Viscosity yog ntau yam thiab siv tau rau ntau hom kua viscosities thiab concentrations.Viscosity NDJ 2% Kev daws, ntawm qhov tod tes, yog qhov tshwj xeeb rau 2% kev daws teeb meem thiab feem ntau siv hauv kev lag luam cellulose los ntsuas kev ua haujlwm ntawm cellulose ethers ntawm qhov concentration.
Hauv kev xaus, Brookfield Viscosity thiab Viscosity NDJ 2% Kev daws yog qhov tseem ceeb rau kev ntsuas viscosity hauv kev lag luam cellulose.Brookfield Viscosity muaj ntau txoj hauv kev uas haum rau ntau yam kua dej ntau thiab viscosities.Hauv qhov sib piv, Viscosity NDJ 2% Kev daws teeb meem muab cov qauv ntsuas rau cellulose ethers ntawm 2% concentration, tso cai rau kev soj ntsuam zoo ib yam ntawm lawv cov kev ua tau zoo hauv kev lag luam cellulose.Los ntawm kev nkag siab txog qhov sib txawv ntawm ob txoj hauv kev no, cov tuam txhab cellulose thiab cov neeg siv tuaj yeem txiav txim siab paub txog kev xaiv cov txheej txheem ntsuas viscosity uas tsim nyog tshaj plaws rau lawv cov kev xav tau tshwj xeeb thiab kev siv.
