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

Carboxymethyl cellulose (CMC) feem ntau yog siv rau hauv cov tshuaj mortar qhuav hauv kev tsim kho kev lag luam vim nws cov khoom tshwj xeeb. Nov yog li cas CMC siv rau hauv cov tshuaj khib nyiab qhuav:

1. Kev tuav dej: CMC ua tus neeg saib xyuas dej hauv cov tshuaj khib nyiab qhuav. Nws pab tiv thaiv kom tsis txhob poob dej sai thaum sib tov thiab thov, tso cai rau kev txhim kho kev ua haujlwm thiab ncua sijhawm qhib. Qhov no ua kom ntseeg tau tias cov tshuaj khib nyiab tseem muaj dej txaus rau kev kho kom zoo thiab adhesion rau substrates.
2. Txhim Kho Kev Ua Haujlwm Zoo: Qhov sib ntxiv ntawm CMC txhim kho kev ua haujlwm ntawm cov tshuaj khib nyiab qhuav los ntawm kev txhim kho nws qhov sib xws, sib kis tau, thiab yooj yim rau kev thov. Nws txo cov luag thiab tsis kam thaum lub sij hawm troweling los yog kis tau, ua rau smoother thiab ntau yam daim ntawv thov ntawm ntsug los yog overhead nto.
3. Enhanced Adhesion: CMC txhim khu cov adhesion ntawm qhuav mortar rau ntau yam substrates, xws li pob zeb, masonry, ntoo, thiab hlau. Nws txhim kho kev sib raug zoo ntawm cov tshuaj khib thiab cov substrate, txo qhov kev pheej hmoo ntawm delamination lossis detachment thaum lub sijhawm.
4. Txo Shrinkage thiab Cracking: CMC pab txo qis shrinkage thiab tawg hauv cov khib nyiab qhuav los ntawm kev txhim kho nws cov cohesion thiab txo cov dej evaporation thaum kho. Qhov no ua rau muaj kev ruaj khov thiab tawg-resistant mortar uas tuav nws txoj kev ncaj ncees nyob rau lub sijhawm.
5. Tswj Lub Sijhawm Teeb Meem: CMC tuaj yeem siv los tswj lub sijhawm teem sijhawm ntawm mortar qhuav los ntawm kev kho nws tus nqi dej thiab rheological zog. Qhov no tso cai rau cov neeg cog lus los kho lub sijhawm teeb tsa kom haum rau cov kev xav tau tshwj xeeb thiab ib puag ncig ib puag ncig.
6. Enhanced Rheology: CMC txhim kho cov khoom rheological ntawm cov tshuaj mortar qhuav, xws li viscosity, thixotropy, thiab shear thinning cwj pwm. Nws ua kom cov dej ntws zoo ib yam thiab cov yam ntxwv zoo sib xws, ua kom yooj yim rau daim ntawv thov thiab ua tiav ntawm cov tshuaj khib rau ntawm qhov chaw tsis xwm yeem lossis textured.
7. Txhim kho Sandability thiab Finish: Lub xub ntiag ntawm CMC nyob rau hauv mortar qhuav ua rau smoother thiab ntau yam xim, uas yooj yim rau xuab zeb thiab tag. Nws txo qhov roughness, porosity, thiab defects ntawm qhov chaw, uas ua rau ib tug high-zoo tag uas yog npaj rau painting los yog kho kom zoo nkauj.

Qhov sib ntxiv ntawm Carboxymethyl cellulose (CMC) kom qhuav mortar formulations txhim khu lawv cov kev ua tau zoo, kev ua haujlwm, durability, thiab zoo nkauj, ua rau lawv tsim nyog rau ntau yam kev tsim kho, nrog rau kev kho pobzeb, plastering, thiab kho qhov chaw.
