Carboxymethyl Cellulose (CMC) nyob rau hauv qhuav mortar hauv kev tsim kho

Carboxymethyl Cellulose (CMC) yog ntau yam thiab dav siv polymer hauv kev tsim kho kev lag luam, tshwj xeeb hauv kev tsim cov mortar qhuav. Qhuav mortar yog ib qho kev sib xyaw ua ntej sib xyaw ntawm cov xuab zeb, cement, thiab cov khoom ntxiv, uas yog siv los tsim cov tsev thaiv lossis kho cov khoom puas. Nov yog qee txoj hauv kev uas CMC siv rau hauv cov tshuaj khib nyiab qhuav:

1. Kev tuav dej: CMC yog siv rau hauv cov tshuaj mortar qhuav ua tus neeg saib xyuas dej. Nws pab txhim kho kev ua haujlwm ntawm cov tshuaj khib nyiab los ntawm kev ua kom nws muaj peev xwm khaws cov dej, uas txo cov dej uas evaporates thaum lub sijhawm kho.
2. Kev hloov kho Rheology: CMC tuaj yeem siv los ua kev hloov kho rheology hauv cov tshuaj khib nyiab qhuav, pab tswj cov dej ntws thiab sib xws ntawm cov tshuaj khib nyiab. Nws tuaj yeem siv los ua kom tuab los yog nyias cov mortar, nyob ntawm qhov xav tau kawg.
3. Adhesion: CMC txhim kho cov khoom adhesion ntawm mortar qhuav los ntawm kev txhim kho kev sib raug zoo ntawm cov tshuaj khib thiab cov tsev thaiv.
4. Txhim kho kev ua haujlwm zoo: CMC txhim kho kev ua haujlwm ntawm cov mortar qhuav los ntawm kev txhim kho nws cov khoom ntws thiab txo cov dej uas xav tau hauv kev tsim.
5. Kev txhim kho durability: CMC txhim kho cov kav ntev ntawm cov mortar qhuav los ntawm kev ua kom nws tsis kam tawg thiab shrinking, uas pab tiv thaiv kev puas tsuaj rau cov qauv.

Zuag qhia tag nrho, kev siv CMC nyob rau hauv qhuav mortar formulations muaj ntau yam txiaj ntsig, nrog rau kev txhim kho dej tuav, hloov kho rheology, adhesion, workability, thiab durability. Cov khoom no ua rau nws yog ib qho tseem ceeb hauv kev tsim kho kev lag luam, tshwj xeeb tshaj yog rau kev tsim cov khoom zoo thiab siv sij hawm ntev qhuav mortar formulations.
