Qhov sib txawv ntawm cov qauv Hydroxypropyl methylcellulose

Hydroxypropyl methyl cellulosemuab faib ua 2 hom dej txias uas yaj sai thiab kub.

1. Gypsum series Hauv cov khoom gypsum series, cellulose ethers feem ntau yog siv los khaws dej thiab ua kom du. Ua ke lawv muab qee qhov kev pab. Nws tuaj yeem daws qhov kev tsis ntseeg ntawm lub nruas tawg thiab lub zog pib thaum lub sijhawm thov, thiab ua kom lub sijhawm ua haujlwm ntev.

2. Hauv cov khoom siv cement putty, cellulose ether feem ntau ua lub luag haujlwm ntawm kev khaws dej, kev nplaum thiab kev du, tiv thaiv kev tawg thiab kev qhuav dej los ntawm kev poob dej ntau dhau, thiab lawv ua ke txhim kho kev nplaum ntawm putty thiab txo qhov tshwm sim ntawm cov txheej txheem kev tsim kho. sag phenomenon, thiab ua rau kev tsim kho du dua.

3. Hauv kev lag luam txheej xim ntawm cov xim latex, cellulose ethers tuaj yeem siv ua cov neeg sawv cev tsim zaj duab xis, cov khoom ua kom tuab, cov khoom ua kom emulsifiers thiab cov khoom ruaj khov, yog li lawv muaj kev tiv thaiv zoo hnav, kev ua haujlwm ntawm cov txheej txheem sib xws, kev nplaum thiab PH tus nqi, thiab tau txhim kho qhov nro ntawm qhov chaw. Nws kuj ua haujlwm zoo thaum sib xyaw nrog cov kuab tshuaj organic, thiab nws cov dej khaws cia siab ua rau nws zoo heev rau kev txhuam thiab kev sib npaug.

4. Tus neeg sawv cev interfacial feem ntau yog siv ua cov khoom tuab, uas tuaj yeem txhim kho lub zog tensile thiab shear zog, txhim kho qhov txheej txheem saum npoo, thiab txhim kho qhov adhesion thiab bonding zog.

5. Cov cellulose ether hauv daim ntawv no tsom mus rau kev sib txuas thiab ua kom muaj zog, ua rau cov mortar yooj yim dua rau kev siv thiab txhim kho kev ua haujlwm zoo. Cov nyhuv tiv thaiv kev poob qis, kev ua haujlwm khaws dej siab dua tuaj yeem ua rau lub sijhawm ua haujlwm ntawm cov mortar ntev dua, txhim kho kev tiv thaiv kev luv luv thiab tawg, txhim kho qhov ntau ntawm qhov chaw thiab txhim kho lub zog sib txuas.

6, Honeycomb ceramics Hauv cov honeycomb ceramics tshiab, cov khoom muaj du, khaws dej thiab lub zog.

7. Qhov nce ntawm sealant, suture cellulose ether ua rau nws muaj qhov zoo heev ntug adhesion, txo qis tus nqi thiab siab hnav tsis kam, thiab tiv thaiv cov ntaub ntawv hauv qab los ntawm kev puas tsuaj kho tshuab, tiv thaiv kev cuam tshuam ntawm soaking rau txhua qhov kev tsim kho.

8. Qhov kev nplaum ruaj khov ntawm cov cellulose ether uas ua rau nws tus kheej zoo ua kom muaj kev nplua zoo thiab muaj peev xwm ua kom nws tus kheej zoo, thiab qhov ceev ntawm kev khaws dej ua rau nws teeb tsa sai thiab txo qhov tawg thiab luv.

9. Cov tshuaj nplaum plastering mortar muaj cov dej khaws cia siab kom ua rau cov cement hydrate tag nrho, ua rau lub zog sib txuas ntxiv ntau ntxiv, thiab tib lub sijhawm ua rau lub zog tensile thiab shear nce ntxiv, uas ua rau cov txiaj ntsig ntawm kev tsim kho zoo dua thiab ua rau kev ua haujlwm zoo dua.

10. Cov nplaum pobzeb uas khaws dej tau zoo tsis tas yuav tsum tau ua ntej impregnation lossis ntub cov pobzeb thiab txheej hauv qab, uas ua rau lub zog sib txuas zoo dua. Lub sijhawm tsim cov slurry ntev, kev tsim kho zoo thiab sib xws, kev tsim kho yooj yim, thiab nws muaj kev tiv thaiv zoo heev.
