Hauv thaj chaw ntawm cov ntaub ntawv tsim kho, cov binders ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ncaj ncees thiab ua haujlwm ntev ntawm ntau yam qauv. Thaum nws los txog rau cov ntawv thov tiling, cov ntaub ntawv tseem ceeb yog qhov tseem ceeb rau kev ruaj ntseg cov vuas rau qhov chaw zoo. Ib qho piv txwv zoo li no tau txais kev saib xyuas zoo rau nws cov khoom siv ntau yam thiab eco-friendly xwm yog Hydroxyethyl Methyl Cellulose (HEMC).
1. Nkag siab HEMC:
Hydroxyethyl Methyl Cellulose (HEMC) yog ib qho uas tsis yog-ionic cellulose ether muab los ntawm ntuj cellulose los ntawm kev hloov kho tshuaj lom neeg. Nws yog cov hmoov dawb dawb dawb, tsis muaj ntxhiab, thiab tsis qab ntsev uas yog soluble hauv dej thiab tsim cov pob tshab, kua nplaum. HEMC yog tsim los ntawm kev kho cellulose nrog alkali thiab tom qab ntawd ua rau nws nrog ethylene oxide thiab methyl chloride. Cov khoom tsim tau nthuav tawm cov khoom sib xyaw ua ke uas ua rau nws tsim nyog rau ntau yam kev siv, suav nrog cov pobzeb khi.
2. Cov khoom ntawm HEMC Muaj feem cuam tshuam rau pobzeb khi:
Kev tuav dej: HEMC muaj cov khoom tuav dej zoo, uas yog qhov tseem ceeb rau cov nplaum nplaum. Nws pab tswj cov dej noo tsim nyog hauv cov nplaum sib tov, tso cai rau kom muaj dej txaus ntawm cov ntaub ntawv cementitious thiab ua kom pom kev zoo rau ob lub pobzeb thiab substrate.
Thickening Effect: HEMC ua raws li tus neeg sawv cev thickening thaum ntxiv rau cov qauv dej. Nws imparts viscosity rau cov nplaum sib tov, tiv thaiv sagging los yog slumping ntawm cov vuas thaum thov. Cov nyhuv thickening no kuj pab txhawb kev ua haujlwm zoo dua thiab yooj yim ntawm daim ntawv thov.
Zaj duab xis tsim: Thaum ziab, HEMC tsim cov zaj duab xis hloov tau yooj yim thiab cohesive rau ntawm qhov chaw, uas ua rau kom muaj zog ntawm cov pobzeb thiab cov substrate. Cov yeeb yaj kiab no ua raws li kev tiv thaiv kev tiv thaiv, txhim kho qhov tsis kam ntawm cov nplais nplaum rau ib puag ncig yam xws li noo noo thiab kub hloov pauv.
Txhim Kho Kev Ua Haujlwm Zoo: Kev sib ntxiv ntawm HEMC rau cov nplais nplaum nplaum txhim kho lawv txoj haujlwm ua haujlwm los ntawm kev txo cov nplaum nplaum thiab txhim kho kev sib kis. Qhov no tso cai rau smoother thiab ntau daim ntawv thov ntawm cov nplaum, uas ua rau kom zoo dua kev pab them nqi thiab adhesion ntawm cov vuas.
3. Kev siv HEMC hauv pobzeb khi:
HEMC pom kev siv dav hauv ntau daim ntawv thov pobzeb khi, suav nrog:
Pobzeb Adhesives: HEMC feem ntau yog siv los ua cov khoom tseem ceeb hauv cov nplais nplaum vim nws muaj peev xwm txhim kho adhesion, workability, thiab dej tuav. Nws yog tshwj xeeb tshaj yog haum rau nyias-txaj pobzeb installation qhov twg ib tug du thiab uniform nplaum txheej yuav tsum tau.
Grouts: HEMC kuj tuaj yeem muab tso rau hauv cov pobzeb grout formulations los txhim kho lawv cov kev ua tau zoo. Nws txhim kho cov khoom ntws ntawm cov sib tov sib xyaw, tso cai rau kom yooj yim sau cov pob qij txha thiab zoo dua compaction nyob ib ncig ntawm cov vuas. Tsis tas li ntawd, HEMC pab tiv thaiv kom tsis txhob shrinkage thiab tawg hauv cov grout thaum nws kho.
Self-Leveling Compounds: Nyob rau hauv tus kheej-leveling pem teb tebchaw siv rau kev npaj subfloors ua ntej cov pobzeb installation, HEMC ua raws li ib tug rheology modifier, xyuas kom meej txaus txaus thiab theem ntawm cov khoom. Nws pab kom ua tiav qhov du thiab txawm nto, npaj rau daim ntawv thov ntawm cov vuas.
4. Cov txiaj ntsig ntawm kev siv HEMC ua cov pobzeb Binder:
Txhim kho Adhesion: HEMC txhim kho kev sib raug zoo ntawm cov vuas thiab cov substrates, ua rau cov pobzeb ruaj khov thiab kav ntev.
Txhim Kho Kev Ua Haujlwm Zoo: Qhov sib ntxiv ntawm HEMC txhim kho kev ua haujlwm thiab kev sib kis ntawm cov nplais nplaum thiab cov grouts, ua rau lawv yooj yim rau kev thov thiab txo lub sijhawm teeb tsa.
Kev tuav dej: HEMC pab tswj kom pom cov dej noo nyob rau hauv cov nplais nplaum nplaum, txhawb nqa dej kom zoo ntawm cov ntaub ntawv cementitious thiab txo qhov kev pheej hmoo ntawm cov nplaum tsis ua haujlwm.
Txo Shrinkage thiab Cracking: Cov yeeb yaj kiab tsim cov khoom ntawm HEMC ua rau txo qis thiab tawg hauv cov nplais nplaum thiab cov nplaum, ua kom ruaj khov thiab txhim khu kev qha thaum lub sijhawm.
Environmentally Friendly: Raws li cov cellulose-raws li polymer tau los ntawm cov khoom siv txuas ntxiv, HEMC yog ib puag ncig tus phooj ywg thiab muaj kev ruaj ntseg, ua rau nws yog qhov kev xaiv zoo rau cov phiaj xwm ntsuab.
5. Xaus:
Hydroxyethyl Methyl Cellulose (HEMC) muaj ntau yam khoom uas ua rau nws yog ib qho zoo tagnrho khi rau pobzeb installation. Nws cov dej tuav, thickening, zaj duab xis-tsim, thiab kev ua haujlwm-txhim kho cov khoom ua rau txhim kho adhesion, durability, thiab yooj yim ntawm daim ntawv thov nyob rau hauv ntau yam ntaub ntawv sib khi daim ntaub ntawv. Nrog nws cov xwm txheej hauv eco-phooj ywg thiab ua pov thawj kev ua tau zoo, HEMC tseem yog qhov kev xaiv zoo tshaj plaws rau cov neeg cog lus thiab cov neeg tsim khoom nrhiav kev daws teeb meem zoo thiab ruaj khov rau cov phiaj xwm tiling.
