Carboxymethyl cellulose (cmc) hauv cov tshuaj khib qhuav hauv kev tsim kho

Carboxymethyl cellulose (CMC) feem ntau siv hauv cov tshuaj tov qhuav hauv kev tsim kho kev lag luam vim nws cov khoom tshwj xeeb. Ntawm no yog li cas cmc tau siv hauv cug qhuav:

1. Dej khaws cia: CMC ua raws li cov dej tswj kav hauv cov tshuaj txhuam hniav qhuav. Nws pab tiv thaiv kom tsis txhob poob dej sai thaum sib xyaw thiab kev thov, pub rau kev txhim kho lub zog ua haujlwm thiab qhib lub sijhawm qhib. Qhov no ua kom pom tseeb tias lub tshuaj khib tseem noj txaus rau kev kho tus kheej kom zoo thiab cov nplaum kom ua tiav.
2. Txhim kho kev ua haujlwm: Qhov sib ntxiv ntawm CMC txhim kho lub zog ntawm cov cap muag los ntawm kev txhim kho nws cov kev sib xws, thiab yooj yim ntawm daim ntawv thov. Nws txo cov cab thiab kev tawm tsam thaum troweling lossis kis mus, ua rau cov ntawv thov kom ntsug ntawm ntsug lossis ua haujlwm tshaj plaws.
3. Txhim kho Adhesion: CMC txhim kho cov nplaum ntawm cug cug qhuav rau ntau yam substrates, xws li pob zeb, ntoo, thiab hlau. Nws txhim kho cov nyiaj sib xyaw thiab cov txheej txheem, txo qhov kev pheej hmoo ntawm kev cuam tshuam lossis tshem tawm lub sijhawm.
4. Txo cov shrinkage thiab tawg: CMC pab kom txo qis shrinkage thiab tawg hauv cov cohesion qhuav los ntawm kev txhim kho cov dej ntws ntuj thaum kho. Qhov no ua rau muaj qhov ntev thiab tawg-resistant cort uas tswj nws kev ncaj ncees nyob rau lub sijhawm.
5. Lub sijhawm tswj lub sijhawm: CMC tuaj yeem siv los tswj lub sijhawm ua kom qhuav los ntawm kev kho nws cov nqi hydration thiab rheological cov khoom. Qhov kev tso cai no ua rau cov neeg cog lus los kho lub sijhawm teem kom haum cov kev xav tau tshwj xeeb thiab ib puag ncig.
6. Txhim khu rhuaology: CMC txhim kho cov yam ntxwv qhuav ntawm cov kab hlau ua kom qhuav, xws li viscosity, thixotrostropy, thiab shear thinning tus cwj pwm. Nws ua kom muaj zog sib xws thiab cov nqi qib siab, yooj yim ntawm cov ntawv thov thiab xov cug ntawm cov chaw tsis xwm yeem lossis cov kab ntawv.
7. Txhim kho cov khoom siv suab paj nruag thiab ua tiav: muaj ntawm cov cmc hauv cov cmc qhuav ua rau smoother thiab ntau cov khoom sib txawv, uas yooj yim rau cov xuab zeb thiab ua tiav. Nws txo qis saum npoo roughness, porosity, thiab nto tsis zoo, ua rau muaj kev ua tiav zoo uas tau npaj txhij rau kev pleev xim lossis kho kom zoo nkauj.

Qhov sib ntxiv ntawm carboxymethyl cellulose (CMC) kom qhuav lawv cov kev ua tau zoo, ua rau muaj kev siv rau cov khoom siv kho, nrog rau kev kho pobzeb, thiab kho kom ntuas kom yooj yim.
