Dab tsi ntawm cov tuab ntawm cov xim pleev xim rau hauv cov kob?

Dej-raws li cov xim tha xim uas hais txog cov xim pleev xim uas siv cov dej ua cov kuab tshuaj lossis tsis sib thooj. Cov xim pleev xim dej tau dhau los ua cov xim pleev xim rau yav tom ntej vim nws cov nqi tsis muaj kuab, tsis muaj nqi viscosity, tsis-irritating, thiab tsis muaj nplaim taws, thiab tsis muaj nplaim taws, thiab tsis muaj cov kab mob uas tsis muaj hluav taws xob, thiab cov nplaim hluavtaws tsis muaj nplaim taws. Cov xim ntxiv tau siv rau hauv cov xim pleev xim me me hauv cov xim pleev xim rau hauv cov dej pleev xim, tab sis lawv tuaj yeem txhim kho kev ua tau zoo ntawm cov xim tha xim thiab tau dhau los ua cov xim tha xim tsis tseem ceeb.Tuabyog ib tug rheological ntxiv uas tsis tuaj yeem tsuas yog thicken xim thiab tiv thaiv sagging thaum lub sij hawm tsim kho, tab sis kuj muab cov xim ua xim zoo nkauj thiab kev ruaj khov. Rau cov xim pleev xim rau dej nrog cov viscosity qis, nws yog ib hom tseem ceeb tshaj plaws ntxiv.

Dej raws li cov xim pleev xim tuab tuaj yeem txhim kho cov khoom siv ntawm cov xim thiab pab txhim kho cov pseudoplastic ntawm cov xim tha xim. Thaum tus nqi tshee siab siv, cov xim tuaj yeem tau yooj yim thinned yooj yim, thiab thaum shear nres lossis qis shear zog yog siv, cov xim muaj peev xwm ua kom tuab dua. Cov yam ntxwv no tuaj yeem, ntawm ib sab tes, txhim kho kev cia ruaj khov ntawm cov xim thiab zam qhov kev ua kom dej ntawm cov pigments thiab fillers hauv cov xim. Nyob rau tib lub sijhawm, thaum lub sij hawm txau txheej txheem, lawv pab ua cov xim atomization ntawm cov xim pleev xim rau cov dej. Ntawm qhov tod tes, thaum lub sijhawm tsim qauv, lawv tuaj yeem tiv thaiv cov sagging ntawm cov xim thiab xyuas kom meej tias cov xim muaj kev tsim kho zoo.

Cia peb mus saib cov yam ntxwv ntawm ntau yam tuab.

1. Cellulosetuab

Cellulosetuabmuaj kev ua tuab tuab, tshwj xeeb tshaj yog rau cov dej tsawg. Lawv muaj tsawg tsawg ntawm cov txheej txheem ua yeeb yam thiab dav PH. Txawm li cas los xij, lawv muaj qee qhov tsis zoo, xws li kev tsis zoo, ntau dua thaum cov menyuam txheej, thiab ntxim nyiam rau cov microbial. Txij li thaum lawv muaj cov viscosity nyob hauv siab nyob rau hauv lub siab zoo nkauj thiab muaj viscosity ntau tom qab txheej, tab sis ntawm qhov tod tes, nws ua rau txoj kev tsis zoo. Cellulose thickeners muaj ib tug loj txheeb ze cov molecular loj, yog li lawv yog tus nquag sib cais. Thiab vim tias cellulose muaj zoo hydrophilicity, nws yuav txo cov dej tsis kam ntawm cov xim pleev xim.

2. Kev Ua Phooj Ywg Polyurethane Thickenters

Lub Koom Haum Kev Koom Tes ntawm Cov Koom Haum Polyurethane Thickeners raug rhuav tshem hauv qab kev ua ntawm shear zog, thiab viscosity yog txo. Thaum lub zog shear ploj, lub viscosity tuaj yeem rov qab los tiv thaiv kev sagging thaum lub sijhawm tsim kho. Thiab nws viscosity rov qab muaj qee qhov hysteresis, uas yog conducive rau theem ntawm txheej zaj duab xis. Cov txheeb ze cov neeg sib txheeb loj ntawm polyurethane thickener yog qhov qis dua uas ntawm thawj ob hom thickeners, thiab nws yuav tsis txhawb kev sib txig. Polyurethane thickener molecules muaj hydrophilic thiab hydrophobic pawg. Cov pab pawg hydrophobic muaj ib qho muaj zog sib xws nrog cov lej sib txawv ntawm cov duab zaj duab xis, uas tuaj yeem txhim kho cov dej tsis kam ntawm cov yeeb yaj kiab txheej.

Vim hais tias cov kua yas txuas nrog hauv lub koom haum, tsis muaj flocculation yuav tshwm sim, uas tuaj yeem ua rau cov duab txheej du thiab muaj qhov zoo dua. Ntau lub zog ntawm cov koom tes polyurethane thickeners zoo dua li lwm cov neeg dute, tab sis vim nws dute fickening hauv cov qauv txheej txheej. Thaum siv hom thickener no, muaj feem ntawm ntau yam ntawm cov tuab ua kev ua tau zoo yuav tsum tau txiav txim siab. Tsis txhob yooj yim hloov lub emulsion, defoober, dispersant, zaj duab xis-ua kev pab, thiab lwm yam siv hauv txheej.

Qingdao Fumaisi High-Tech Cov Khoom Co., Ltd. Tshwj Xeeb Hauv Cov Khoom Ntau Lawm Ntau LawmtuabCov. Lub tuam txhab tau ua tiav rau cov tswvyim ntawm kev tswj hwm zoo thiab kev coj ncaj ncees tau ntau xyoo, thiab sib zog los muab cov khoom lag luam uas muaj peev xwm txhim khu kev qha thiab kev pab muag khoom zoo!
