Ua tus thawj coj Cellulose Ether Chaw Tsim Khoom rau Cov Qhuav Sib Xyaws Mortar
Hauv kev lag luam kev tsim kho niaj hnub no, cov neeg tsim cov tshuaj mortar qhuav vam khom cov cellulose ether zoo kom ua tiav kev ua tau zoo tas li. Xaiv ib qho Tuam Tshoj cellulose ether manufacturer yog qhov tseem ceeb rau kev ua kom muaj kev ua haujlwm tau zoo, kev khaws dej, kev nplaum, thiab kev ua haujlwm ntev ntawm cov kab ke mortar.
Ntawm ntau yam cellulose ethers, Hydroxypropyl Methylcellulose (HPMC) thiab MHEC yog siv dav ua cov khoom siv tseem ceeb. Lawv qhov zoo cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov mortar, ua rau kev xaiv cov neeg muag khoom yog qhov kev txiav txim siab zoo rau cov neeg yuav khoom thoob ntiaj teb.
Vim li cas Cellulose Ether tseem ceeb hauv Cov Pob Zeb Qhuav
Cellulose ether ua haujlwm ua ib qho khoom siv ntxiv rau hauv cov cement-based dry mix mortar. Nws txhim kho kev ua haujlwm, khaws cov dej noo, thiab txhim kho kev sib txuas. Cov yam ntxwv no pab cov neeg ua haujlwm ua tiav kev siv du thiab cov qauv tiav zoo dua.
Hauv cov qauv mortar, cellulose ether feem ntau ua haujlwm li:
- Tus neeg sawv cev khaws dej
- Rheology hloov kho
- Cov khoom ua kom tuab
- Tus neeg sawv cev tiv thaiv kab mob
- Kev txhim kho kev ua haujlwm
Vim tias cov teebmeem no nyob ntawm cov qauv molecular thiab kev tswj hwm kev tsim khoom, kev ua haujlwm nrog cov kws tshaj lij chaw tsim khoom yog qhov tseem ceeb.
Cov Haujlwm Tseem Ceeb ntawm Cellulose Ether hauv Cov Pob Zeb Qhuav
1. Kev Khaws Dej Zoo heev
Cellulose ether tuaj yeem nqus thiab tuav cov dej hauv cov mortar matrix, tiv thaiv kev evaporation ua ntej thiab ua kom cov cement noo zoo. Qhov no ua rau lub zog kawg thiab kev ruaj khov zoo dua.
Cov txiaj ntsig suav nrog:
- Lub sijhawm ua haujlwm ntev dua
- Kev ua kom cov cement noo zoo dua
- Txo qhov kev pheej hmoo ntawm kev tawg
- Kev ua tau zoo dua hauv huab cua kub
2. Kev Ua Haujlwm Zoo Dua thiab Kev Sib Xws
Ua ib qho kev hloov pauv rheology, cellulose ether txo qhov kev sib txhuam sab hauv thiab muab cov qauv mortar du thiab creamy. Qhov no ua rau kev sib tov, twj, thiab troweling yooj yim dua ntawm qhov chaw ua haujlwm.
- Kev sib tov yooj yim dua
- Zoo dua qhov kev xav ntawm trowel
- Daim ntawv thov sib xws
- Kev tsim kho zoo dua
3. Lub zog nplaum zoo dua
Cellulose ether tsim ib daim nyias nyias nyob ib puag ncig cov cement, txhim kho kev sib kis thiab kev sib txuas nrog cov khoom siv xws li pob zeb, cib, thiab vuas.
Qhov no ua rau:
- Lub zog tensile siab dua
- Txo qhov delamination
- Cov txheej txheem mortar ruaj khov dua
4. Kev Tswj Xyuas Kev Tawm Tsam thiab Kev Rheology
Los ntawm kev ua kom viscosity nce ntxiv, cellulose ether pab cov mortar tswj nws cov duab thaum lub sijhawm ntsug lossis saum toj kawg nkaus, tiv thaiv kev sagging lossis slumping.
Qhov no tseem ceeb heev rau:
- Cov nplaum rau pobzeb
- Phab ntsa plaster
- Cov txheej txheem EIFS
- Kho cov tshuaj khib
5. Kev ruaj khov thiab kev tawg tsis kam
Cov cellulose ether uas tsim tau zoo ua rau cov khoom sib txuas zoo dua thiab txo qhov ntsws, ua rau cov mortar tiv taus qhov tawg ntau dua. Nws kuj tseem ua rau kom tiv taus dej noo thiab huab cua zoo dua.
Dab tsi txhais tau tias yog tus thawj coj ntawm Cellulose Ether Chaw Tsim Khoom?
Tsis yog txhua tus neeg muag khoom tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg tsim khoom siv sib tov qhuav niaj hnub no. Cov chaw tsim khoom zoo tshaj plaws feem ntau muab cov txiaj ntsig hauv qab no:
Kev Siv Tshuab Tsim Khoom Siab Tshaj Plaws
- Cov reactors etherification loj
- Kev tswj cov txheej txheem tsis siv neeg
- Qib hloov pauv ruaj khov (DS / MS)

Cov Lus Qhia Txog HPMC Rau Cov Mortar Qhuav
| Cov Qauv | Qhov ntau yam |
|---|---|
| Viscosity (2% kua) | 20,000–200,000 mPa·s |
| Kev Siv Tshuaj | 0.2%–0.6% |
| Cov dej noo | ≤5% |
| Qhov loj ntawm cov khoom me me | 80–100 mesh |
| Kub ntawm cov kua nplaum | 55–75°C |
Kev xaiv qib tseeb yuav tsum tau txheeb xyuas los ntawm kev sim cov mis.
Yuav Ua Li Cas Xaiv Tus Tsim Khoom Zoo
Ua ntej yuav khoom ntau, cov neeg yuav khoom thoob ntiaj teb yuav tsum soj ntsuam cov neeg muag khoom siv daim ntawv teev npe no:
