High-performance cellulose ethers rau kev txhim kho mortar qhuav

Kev ua haujlwm siab ntawm cellulose ethers ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm cov tshuaj khib nyiab qhuav siv hauv kev tsim kho. Cov cellulose ethers, xws li Hydroxypropyl Methylcellulose (HPMC), muaj nuj nqis rau lawv cov khoom rheological, tuav dej, adhesion, thiab tag nrho cov kev pab cuam rau qhov zoo thiab ua hauj lwm ntawm qhuav mortars. Nov yog qhov ua tau zoo ntawm cellulose ethers txhim kho cov tshuaj khib nyiab qhuav li cas:

1. Kev tuav dej:

• Lub luag haujlwm: Cellulose ethers ua raws li cov dej khaws cia, tiv thaiv dej ntau dhau thaum lub sijhawm kho.
• Cov txiaj ntsig:
  • Txhim kho kev ua haujlwm thiab yooj yim ntawm kev thov.
  • Txo qhov kev pheej hmoo ntawm kev tawg thiab shrinkage nyob rau hauv lub mortar tiav.

2. Thickening thiab Rheology Control:

• Lub luag haujlwm:Kev ua tau zoo ntawm cellulose etherspab txhawb rau lub thickening ntawm mortar formulations, cuam tshuam lawv rheological zog.
• Cov txiaj ntsig:
  • Txhim kho qhov sib xws thiab yooj yim ntawm kev thov.
  • Txhim kho adhesion rau qhov chaw ntsug.

3. Txhim kho Adhesion:

• Lub luag hauj lwm: Cellulose ethers txhim khu cov adhesion ntawm qhuav mortar rau ntau yam substrates, nrog rau cov vuas, cib, thiab pob zeb.
• Cov txiaj ntsig:
  • Ua kom muaj kev sib raug zoo thiab kev ua haujlwm ntev ntev ntawm lub mortar.
  • Txo qhov kev pheej hmoo ntawm delamination lossis detachment.

4. Anti-Sagging Properties:

• Lub luag haujlwm: Kev ua haujlwm siab ntawm cellulose ethers pab txhawb rau cov khoom tiv thaiv sagging ntawm mortars, tso cai rau lawv siv rau ntawm qhov chaw ntsug yam tsis muaj slumping.
• Cov txiaj ntsig:
  • Ua kom yooj yim rau daim ntawv thov ntawm phab ntsa thiab lwm cov qauv ntsug.
  • Txo qhov xav tau kev hloov kho tsis tu ncua thaum thov.

5. Kev ua haujlwm tau zoo thiab nthuav dav:

• Lub luag haujlwm: Cellulose ethers txhim kho kev ua haujlwm tag nrho thiab kev sib kis ntawm cov tshuaj khib nyiab qhuav.
• Cov txiaj ntsig:
  • Kev sib xyaw yooj yim dua thiab siv los ntawm cov kws tshaj lij kev tsim kho.
  • Sib npaug thiab sib npaug ntawm qhov chaw.

6. Teem sij hawm tswj:

• Lub luag haujlwm: Qee cov cellulose ethers tuaj yeem cuam tshuam lub sijhawm teem sijhawm ntawm mortars.
• Cov txiaj ntsig:
  • Tso cai rau kev hloov kho hauv lub sijhawm teeb tsa raws li kev tsim kho.
  • Xyuas kom zoo curing thiab hardening ntawm lub mortar.

7. Kev cuam tshuam rau cov khoom kawg:

• Lub luag haujlwm: Kev siv cov cellulose ethers uas ua tau zoo tuaj yeem cuam tshuam qhov kawg ntawm cov tshuaj khib nyiab, xws li lub zog thiab kav ntev.
• Cov txiaj ntsig:
  • Txhim khu kev ua tau zoo thiab lub neej ntev ntawm cov khoom tsim.

8. Compatibility nrog lwm yam additives:

• Lub luag haujlwm: Kev ua haujlwm siab ntawm cellulose ethers feem ntau sib xws nrog lwm cov tshuaj ntxiv uas siv rau hauv cov tshuaj khib nyiab qhuav.
• Cov txiaj ntsig:
  • Pab kom cov neeg tsim qauv tsim kom muaj txiaj ntsig zoo thiab kho cov tshuaj khib nyiab.

9. Kev Pov Hwm Zoo:

• Lub luag haujlwm: Qhov zoo ib yam ntawm kev ua tau zoo ntawm cov cellulose ethers ua kom ntseeg tau thiab kev ua tau zoo hauv ntau daim ntawv thov kev tsim kho.

Kev siv cov cellulose ethers ua haujlwm siab hauv cov tshuaj mortar qhuav daws cov teeb meem tseem ceeb hauv kev tsim kho kev lag luam, muab kev ua haujlwm zoo dua qub, adhesion, thiab tag nrho durability ntawm cov khoom tiav. Kev xaiv tshwj xeeb ntawm cellulose ether thiab nws cov concentration yog nyob ntawm qhov yuav tsum tau ntawm daim ntawv thov mortar thiab cov khoom xav tau ntawm cov khoom kawg.
