HPMC hauv Kev Tsim Kho

Hydroxypropyl methyl cellulose HPMC yog cov khoom siv ntuj tsim polymer cellulose ua raw khoom, los ntawm kev ua tshuaj lom neeg thiab ua los ntawm non-ionic cellulose ether. Lawv yog cov tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom cov hmoov dawb uas nthuav mus rau hauv cov kua dej ntshiab lossis me ntsis cloudy colloid hauv dej txias. Nrog thickening, adhesion, dispersion, emulsification, zaj duab xis tsim, ncua kev kawm ntawv, adsorption, gel, deg kev ua si, noo noo retention thiab colloidal tiv thaiv, thiab lwm yam. Hydroxypropyl methyl cellulose HPMC, methyl cellulose MC yuav siv tau nyob rau hauv lub tsev cov ntaub ntawv, txheej kev lag luam, hluavtaws cob, ceramic kev lag luam, tshuaj, zaub mov, textile, ua liaj ua teb, tshuaj txhua hnub thiab lwm yam kev lag luam.

Chemical Equation:

Cov cuab yeej ntawm HPMC siv hauv Kev Tsim Kho
1. Kev tuav dej
Hydroxypropyl methyl cellulose HPMC rau kev tsim kho tiv thaiv kev nqus dej ntau dhau los ntawm lub substrate, thiab cov dej yuav tsum tau khaws cia hauv plaster ntau li ntau tau thaum ua tiav ntawm gypsum solidification. Cov cuab yeej no yog hu ua dej tuav, thiab yog proportional rau lub viscosity ntawm lub tsev tshwj xeeb hydroxypropyl methyl cellulose HPMC tov nyob rau hauv lub stucco, lub siab dua lub viscosity ntawm cov tshuaj, lub siab dua cov dej tuav peev xwm.
Thaum cov ntsiab lus dej nce ntxiv, cov dej khaws cia muaj peev xwm txo qis, vim tias cov dej nce ntxiv diluted kev tsim kho ntawm hydroxypropyl methyl cellulose HPMC tov, ua rau txo qis hauv viscosity.
2. Sag kuj
Lub stucco uas tiv taus ntws thiab dai tso cai rau tus tsim kom siv cov txheej tuab yam tsis muaj ntsug ntws, uas tseem txhais tau hais tias lub stucco nws tus kheej yog thixotropic, txwv tsis pub nws swb downwards thaum lub sij hawm tsim kho.
3. Txo viscosity, yooj yim siv
Los ntawm kev ntxiv ntau lub tsev tshwj xeeb hydroxypropyl methyl cellulose HPMC cov khoom, tsis tshua muaj viscosity thiab yooj yim siv tau los ntawm gypsum plaster, siv tsawg viscosity theem tsev nplooj siab hydroxypropyl methyl cellulose HPMC, kuj tsawg viscosity thiab yooj yim siv, txawm li cas los, tsawg viscosity tsev siab hydroxypropyl methyl cellulose HPMC dej tuav lub peev xwm tsis muaj zog, yuav tsum tau nce ntxiv.
4. Muaj peev xwm loj hlob ntawm stucco
Rau ib qho kev ruaj khov ntawm cov tshuaj khib nyiab qhuav, nws yog qhov kev lag luam ntau dua los tsim kom muaj cov khoom ntub dej ntau dua, uas tuaj yeem ua tiav los ntawm kev ntxiv dej thiab npuas. Tab sis dej thiab npuas ntau dhau tuaj yeem ua rau lub zog puas tsuaj.
