Hydroxypropylmethylcellulose thiab Surface kho HPMC

Hydroxypropyl methyl cellulose (HPMC) yog ib qho khoom siv polymer uas siv dav hauv ntau yam lag luam, suav nrog kev tsim kho, tshuaj, khoom noj, tshuaj pleev ib ce, thiab kev saib xyuas tus kheej. Nyob rau hauv cov ntsiab lus ntawm kev tsim kho, nto-kho HPMC yog hais txog HPMC uas tau dhau los ua cov txheej txheem ntxiv los hloov nws cov khoom nto, txhim kho nws cov kev ua tau zoo hauv cov ntawv thov tshwj xeeb. Nov yog cov ntsiab lus ntawm HPMC thiab cov txheej txheem kho saum npoo siv hauv kev tsim kho kev lag luam:

Hydroxypropyl Methyl Cellulose (HPMC):

1. Chemical Structure:
   • HPMC yog ib qho cellulose ether muab los ntawm ntuj cellulose, uas yog tshuaj hloov kho los ntawm kev qhia hydroxypropyl thiab methyl pawg mus rau cellulose qaum.
   • Qhov kev hloov kho no ua rau muaj dej-soluble polymer nrog cov thickening zoo heev, khi, zaj duab xis-tsim, thiab dej tuav cov khoom.
2. Muaj nuj nqi hauv Kev Tsim Kho:
   • HPMC yog dav siv nyob rau hauv kev tsim kho raws li ib tug additive nyob rau hauv cement-based khoom xws li mortars, renders, pobzeb adhesives, grouts, thiab self-leveling compounds.
   • Nws ua haujlwm ntau yam, suav nrog kev txhim kho kev ua haujlwm, adhesion, sag resistance, dej tuav, thiab durability ntawm cov khoom kawg.

Kev Kho Hniav ntawm HPMC hauv Kev Tsim Kho:

1. Hydrophobic Surface Hloov Kho:
   • Kev kho deg ntawm HPMC suav nrog kev hloov kho nws qhov chaw kom nws muaj dej ntau dua lossis dej-repellent.
   • Hydrophobic HPMC tuaj yeem tau txais txiaj ntsig zoo hauv qee qhov kev tsim kho uas yuav tsum muaj kev tiv thaiv dej noo, tiv thaiv dej, lossis txhim kho kev ua haujlwm hauv cov dej ntub dej.
2. Customization rau cov ntawv thov tshwj xeeb:
   • HPMC Kev Kho Hniav tuaj yeem hloov kho kom tau raws li cov kev cai tshwj xeeb ntawm kev tsim kho sib txawv.
   • Piv txwv li, nyob rau hauv cov pobzeb nplaum thiab grouts, nto-kho HPMC tuaj yeem txhim kho cov dej tsis kam thiab adhesion ntawm cov khoom, txhim kho nws cov kev ua tau zoo hauv qhov chaw ntub dej xws li chav dej thiab chav ua noj.
3. Txhim kho Compatibility:
   • Kev kho deg ntawm HPMC tuaj yeem txhim kho nws qhov sib raug zoo nrog lwm cov khoom xyaw lossis cov khoom siv ntxiv uas siv hauv cov qauv tsim.
   • Qhov no ua kom zoo dua dispersion, stability, thiab kev ua tau zoo ntawm tag nrho cov khoom, ua rau txhim khu kev ua hauj lwm thiab durability.

Cov txiaj ntsig ntawm Surface-Treated HPMC:

1. Txhim Kho Dej Resistance: HPMC Surface-kho tuaj yeem muab kev tiv thaiv zoo dua rau cov dej nkag thiab cov teeb meem dej noo, xws li efflorescence thiab microbial kev loj hlob.
2. Txhim kho Adhesion: Qhov kev hloov kho saum npoo tuaj yeem txhim kho qhov adhesion ntawm HPMC-raws li cov khoom siv rau ntau lub substrates, uas ua rau muaj kev sib raug zoo thiab kev ua haujlwm ntev ntev.
3. Extended Durability: Los ntawm kev txhim kho cov dej tsis kam thiab adhesion zog, HPMC nto-kho tau pab txhawb rau tag nrho cov kav ntev thiab kev pab cuam lub neej ntawm cov khoom siv.

Xaus:

Kev kho deg ntawm HPMC hauv kev tsim kho suav nrog kev hloov kho nws cov khoom saum npoo los txhim kho nws cov kev ua tau zoo hauv cov ntawv thov tshwj xeeb. Los ntawm kev kho HPMC rau kev txhim kho dej tsis kam, adhesion, thiab compatibility, HPMC nto-kho tau pab rau kev tsim cov khoom siv zoo thiab ruaj khov.
