Cov teebmeem ntawm Cement Slurry nrog Ntxiv ntawm Cellulose Ethers ntawm Ceramic Vuas Bonding

Qhov sib ntxiv ntawm cellulose ethers rau cov cement slurries tuaj yeem muaj ntau yam teebmeem ntawm cov pobzeb ceramic sib txuas hauv cov ntawv nplaum nplaum. Nov yog qee qhov teebmeem tseem ceeb:

1. Txhim kho Adhesion: Cellulose ethers ua raws li cov dej khaws cia thiab cov thickeners hauv cov cement slurries, uas tuaj yeem txhim kho qhov adhesion ntawm cov vuas luaj ceramic rau substrates. Los ntawm kev tswj kom zoo hydration thiab ua kom cov viscosity ntawm slurry, cellulose ethers txhawb kev sib cuag zoo ntawm cov pobzeb thiab substrate, uas ua rau muaj kev sib raug zoo zog.
2. Txo Shrinkage: Cellulose ethers pab txo qis qis hauv cov cement slurries los ntawm kev tswj cov dej evaporation thiab tswj cov dej-rau-cement piv. Qhov kev txo qis hauv qhov shrinkage no tuaj yeem tiv thaiv kev tsim cov voids lossis qhov khoob ntawm cov pobzeb thiab cov substrate, ua rau muaj kev sib txuam ntau dua thiab ruaj khov.
3. Txhim khu kev ua haujlwm zoo: Kev sib ntxiv ntawm cellulose ethers txhim kho kev ua haujlwm ntawm cov cement slurries los ntawm kev ua kom lawv cov dej ntws thiab txo qis qis lossis poob qis thaum siv. Qhov kev txhim kho kev ua haujlwm no tso cai rau kev yooj yim dua thiab meej tso ntawm cov vuas luaj ceramic, ua rau kev txhim kho thiab kev sib txuas.
4. Ua kom muaj zog ntxiv: Cov cement slurries uas muaj cellulose ethers tuaj yeem ua tau zoo dua qub vim lawv cov adhesion zoo dua thiab txo qis. Qhov kev sib raug zoo ntawm cov pobzeb ceramic thiab substrate, ua ke nrog kev tiv thaiv ntawm cov teeb meem cuam tshuam nrog shrinkage, tuaj yeem ua rau cov vuas luaj thiab ntev ntev.
5. Kev Tiv Thaiv Dej Zoo dua: Cellulose ethers tuaj yeem txhim kho cov dej tsis kam ntawm cov cement slurries, uas yog qhov zoo rau cov pobzeb ceramic installation hauv qhov chaw ntub dej lossis ntub dej. Los ntawm khaws cov dej hauv cov slurry thiab txo cov permeability, cellulose ethers pab tiv thaiv dej infiltration tom qab cov vuas, txo qhov kev pheej hmoo ntawm daim ntawv cog lus tsis ua hauj lwm los yog substrate puas thaum lub sij hawm.
6. Txhim kho Lub Sij Hawm Qhib: Cellulose ethers pab txhawb rau ncua sij hawm qhib hauv cov cement slurries, tso cai rau cov sij hawm hloov tau yooj yim dua thiab cov cheeb tsam loj dua los ua cov pobzeb yam tsis muaj kev cuam tshuam kev sib txuas. Lub sijhawm ntev ua haujlwm tau muab los ntawm cellulose ethers ua rau cov neeg tsim khoom ua kom tiav cov pobzeb tso thiab kev hloov kho ua ntej cov nplaum nplaum, uas ua rau muaj kev ruaj khov thiab txhim khu kev qha.

Qhov sib ntxiv ntawm cellulose ethers rau cov cement slurries tuaj yeem cuam tshuam cov pobzeb pobzeb sib txuas los ntawm kev txhim kho adhesion, txo qis shrinkage, txhim kho kev ua haujlwm, ua kom muaj zog, txhim kho dej tsis kam, thiab ncua sijhawm qhib. Cov teebmeem no ua rau muaj txiaj ntsig zoo dua thiab txhim khu kev txhim kho cov txheej txheem pobzeb, ua rau cov pobzeb zoo zoo nrog kev ua haujlwm zoo thiab ua haujlwm ntev.
