Thaum ua thiab siv cov hmoov putty, peb yuav ntsib ntau yam teeb meem. Niaj hnub no, qhov peb tab tom tham txog yog tias thaum cov hmoov sib tov sib xyaw nrog dej, qhov ntau koj do, qhov thinner lub putty yuav dhau los, thiab qhov tshwm sim ntawm kev sib cais dej yuav loj heev.
Lub hauv paus ua rau ntawm qhov teeb meem no yog tias hydroxypropyl methylcellulose ntxiv rau hauv cov hmoov putty tsis haum. Cia wb mus saib lub hauv paus ntsiab lus ntawm kev ua haujlwm thiab peb yuav daws tau li cas.
Lub hauv paus ntsiab lus ntawm cov hmoov putty tau thinner thiab thinner:
1. Lub viscosity ntawm hydroxypropyl methylcellulose yog xaiv tsis raug, lub viscosity tsawg dhau, thiab cov nyhuv ncua tsis txaus. Nyob rau lub sijhawm no, kev sib cais dej hnyav yuav tshwm sim, thiab qhov cuam tshuam tsis zoo yuav tsis cuam tshuam;
2. Ntxiv dej-retaining tus neeg sawv cev rau putty hmoov, uas muaj ib tug zoo dej-retaining nyhuv. Thaum lub putty dissolves nrog dej, nws yuav kaw ib tug loj npaum li cas ntawm cov dej. Nyob rau lub sijhawm no, dej ntau yog flocculated rau hauv pawg dej. Nrog stirring dej ntau yog sib cais, yog li ib qho teeb meem tshwm sim yog qhov ntau koj do, qhov thinner nws ua. Ntau tus neeg tau ntsib qhov teeb meem no, koj tuaj yeem txo cov cellulose ntxiv los yog txo cov dej ntxiv;
3. Nws muaj qee yam kev sib raug zoo nrog cov qauv ntawm hydroxypropyl methylcellulose thiab muaj thixotropy. Yog li ntawd, tom qab ntxiv cellulose, tag nrho cov txheej muaj ib tug tej yam thixotropy. Thaum lub putty yog stirred sai, nws tag nrho cov qauv yuav disperse thiab ua thinner thiab thinner, tab sis thaum nws tseem tshuav, nws yuav maj mam rov qab.
Kev daws: Thaum siv cov hmoov putty, feem ntau ntxiv dej thiab do kom nws ncav cuag ib theem tsim nyog, tab sis thaum ntxiv dej, koj yuav pom tias cov dej ntau ntxiv, qhov thinner nws ua. Qhov no yog vim li cas?
1. Cellulose yog siv los ua cov thickener thiab dej-retaining tus neeg sawv cev hauv putty hmoov, tab sis vim yog thixotropy ntawm cellulose nws tus kheej, qhov sib ntxiv ntawm cellulose hauv putty hmoov kuj ua rau thixotropy tom qab ntxiv dej rau lub putty;
2. Qhov thixotropy no yog tshwm sim los ntawm kev puas tsuaj ntawm cov qauv xoob xoob ntawm cov khoom hauv cov hmoov putty. Cov qauv no yog tsim los ntawm so thiab dismantled nyob rau hauv kev ntxhov siab, uas yog hais tias, lub viscosity txo nyob rau hauv stirring, thiab lub viscosity ntawm so rov qab, yog li yuav muaj ib tug tshwm sim uas cov hmoov putty yuav thinner li nws ntxiv nrog dej;
3. Tsis tas li ntawd, thaum siv cov hmoov putty, nws dries sai heev vim hais tias cov hmoov tshauv calcium ntau ntxiv muaj feem xyuam rau cov dryness ntawm phab ntsa. Lub tev thiab dov ntawm cov hmoov putty muaj feem xyuam rau cov dej tuav tus nqi;
4. Yog li ntawd, txhawm rau zam qhov xwm txheej tsis tsim nyog, peb yuav tsum tau xyuam xim rau cov teeb meem no thaum siv nws.
