Hydroxypropyl methylcellulose (HPMC) yog ntau yam polymer nrog kev siv ntau yam kev lag luam. Nws txoj kev siv yuav txawv nyob ntawm cov ntawv thov tshwj xeeb thiab kev lag luam.
1. Kev tsim kho kev lag luam:
HPMC feem ntau siv rau hauv cov khoom siv xws li cement-based mortars, pobzeb adhesives thiab grouts.
Cov nqi siv rau hauv cov tshuaj khib nyiab yog li ntawm 0.1% mus rau 0.5% los ntawm qhov hnyav.
Hauv cov nplais pobzeb nplaum, HPMC tau ntxiv rau hauv qhov nyiaj ntawm 0.2% rau 0.8% txhawm rau txhim kho kev ua haujlwm thiab kev ua haujlwm.
2. Tshuaj:
Hauv kev lag luam kws kho mob, HPMC yog siv los ua cov khoom siv tshuaj hauv cov ntsiav tshuaj, tshuaj ntsiav thiab qhov muag poob formulations.
Tus nqi siv nyob rau hauv cov ntsiav tshuaj formulations feem ntau yog nruab nrab ntawm 2% thiab 5%, ua raws li ib tug binder thiab tso tawm tus neeg saib xyuas.
Rau cov tshuaj kho qhov muag pom kev, HPMC yog siv qis dua ntawm kwv yees li 0.3% mus rau 1%.
3. Kev lag luam zaub mov:
HPMC yog siv nyob rau hauv kev lag luam khoom noj khoom haus ua cov thickener thiab stabilizer.
Kev siv cov khoom noj tuaj yeem sib txawv tab sis feem ntau yog nyob ntawm 0.1% txog 1%.
4. Xim thiab Txheej:
Hauv cov xim thiab txheej, HPMC yog siv los ua cov thickener, muab kev txhim kho viscosity thiab sag kuj.
Tus nqi siv hauv txheej txheej tuaj yeem yog li ntawm 0.1% mus rau 1%.
5. Cov khoom siv tu tus kheej:
HPMC yog siv rau hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej xws li tshuaj pleev, tshuaj pleev thiab tshuaj zawv plaub hau.
Kev siv tus nqi rau cov khoom no feem ntau yog li ntawm 0.1% mus rau 2%.
6. Kev lag luam roj thiab roj:
Hauv kev lag luam roj thiab roj, HPMC yog siv los ua cov tackifier hauv cov kua dej drilling.
Tus nqi siv nyob rau hauv drilling kua formulations muaj li ntawm 0.1% mus rau 1%.
7. Textile kev lag luam:
HPMC yog siv nyob rau hauv kev lag luam textile raws li tus neeg sawv cev sizing rau warp yarns.
Textile sizing siv tus nqi sib txawv, tab sis feem ntau yog li ntawm 0.1% mus rau 2%.
8. Adhesives thiab sealants:
Hauv cov nplaum thiab cov sealants, HPMC yog siv los txhim kho kev sib raug zoo thiab cov khoom rheological.
Kev siv tus nqi hauv cov tshuaj nplaum tuaj yeem nyob ntawm 0.1% mus rau 1%.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov nqi siv no yog cov lus qhia dav dav nkaus xwb thiab cov qauv tsim tshwj xeeb yuav tsum tau hloov kho raws li qhov xav tau. Tsis tas li ntawd, cov kev cai thiab cov qauv yuav cuam tshuam rau kev tso cai siv HPMC hauv ntau daim ntawv thov. Cov neeg tsim khoom thiab cov kws tsim qauv yuav tsum nco ntsoov xa mus rau cov kev taw qhia tseem ceeb thiab ua qhov kev sim tsim nyog rau lawv cov qauv tsim tshwj xeeb
