Hydroxypropyl methylcellulose yog sivfeem ntau yog siv nyob rau hauv ntau yam lag luam. Txawm hais tias ntau tus neeg tsis nkag siab nws zoo heev, nws cuam tshuam rau ntau yam kev lag luam. Nyob rau hauv cov txheej txheem ntawm kev tsim kho kev lag luam, nws yog feem ntau yog siv rau phab ntsa tsev thiab stucco kho kom zoo nkauj, Caulking thiab lwm yam mechanical siv teb, tshwj xeeb tshaj yog nyob rau hauv kev tsim kho kom zoo nkauj, nws yog feem ntau siv rau tiling, marble, thiab ib co yas decorations. Nws muaj qib siab ntawm adhesion thiab tuaj yeem txo cov cement siv. Nws yog siv rau hauv kev lag luam txheej, feem ntau yog siv los ua cov thickener, tuaj yeem ua rau txheej txheej zoo thiab ci, tsis yooj yim tshem cov hmoov, txhim kho qib kev ua tau zoo, thiab lwm yam, tshwj xeeb tshaj yog rau daim ntawv thov nyob rau hauv lub tshav pob ntawm lub tsev self-leveling mortar.
Tus kheej-leveling xuab zeb khoom plig yog qhov tshwj xeeb qhuav-sib xyaw mortar khoom nrog leveling thiab nws tus kheej-compacting zog. Nws tus kheej-compacting thiab self-leveling muaj peev xwm yog qhov tseem ceeb heev rau kev ua tiav ib txheej seamless thiab du hauv av. Rau cov khoom lag luam zoo tus kheej, ua ntej Nws yuav tsum muaj kev ua haujlwm tsim nyog, thiab muaj peev xwm tswj tau nws qhov kev ua tau zoo tag nrho thiab kho tus kheej lub peev xwm hauv lub sijhawm tsim kho. Nyob rau hauv no txoj kev, qhov no yuav tsum tau lub mortar kom tag nrho nws stability thiab uniformity nyob rau hauv lub sij hawm ntawm lub sij hawm no. Qhov thib ob, lub mortar yuav tsum muaj qee lub zog, uas suav nrog cov kabmob muaj peev xwm thiab lub zog sib txuas rau lub hauv paus nto. Cov no yog cov xwm txheej yooj yim rau kev siv cov ntaub ntawv ntawm tus kheej, thiab kev ua tiav ntawm cov khoom ntawm tus kheej-leveling yuav tsum tau hydroxypropyl ntxiv ntawm methyl cellulose ether tuaj yeem ua kom tuab thiab nce viscosity, thiab tseem muaj cov yam ntxwv ntawm cov dej khaws cia siab thiab ua kom lub sijhawm tsim kho.
Qhov siab dua qhov viscosity ntawm hydroxypropyl methylcellulose, qhov zoo dua qhov viscosity ntawm cov khoom siv cement-based hloov, tab sis yog tias cov viscosity siab dhau lawm, nws yuav cuam tshuam rau qhov fluidity thiab kev ua haujlwm ntawm cov khoom. Tsis tas li ntawd, cov nyhuv thickening ntawm hydroxypropyl methylcellulose tuaj yeem ua rau kom cov dej xav tau ntawm cov khoom siv cement, yog li ua kom cov qoob loo ntawm mortar. Self-leveling mortar thiab self-compacting pob zeb, uas yuav tsum tau muaj fluidity, yuav tsum tau tsawg viscosity ntawm hydroxypropyl methylcellulose. Lub low-viscosity cellulose ether tuaj yeem ua rau muaj kev cuam tshuam zoo, tiv thaiv cov slurry los ntawm kev daws teeb meem, thiab tseem muaj cov haujlwm los ntshav, uas tuaj yeem xyuas kom meej tias nws yuav tsis cuam tshuam cov nyhuv ntws ntawm tus kheej-leveling mortar khoom, yooj yim rau kev tsim, thiab muaj dej tuav cov yam ntxwv tuaj yeem ua rau cov nyhuv ntog tom qab leveling zoo dua, txo cov shrinkage ntawm cov mortar thiab tev.
Hydroxypropyl methylcellulose yog siv dav hauv ntau yam khoom siv hauv tsev. Thaum siv rau hauv tus kheej-leveling mortar, nws muaj cov yam ntxwv hauv qab no:
1. Cov dej tuav tau zoo tuaj yeem ua kom ntev lub sijhawm ua haujlwm ntawm tus kheej-leveling mortar, txhim kho lub zog ntawm mortar, ua kom nws lub zog sib txuas, thiab kev ua haujlwm ntub dej zoo tuaj yeem txo cov av tshauv.
2. Muaj zog sib raug zoo, haum rau txhua yam ntawm cov khoom siv hauv tsev, nws tus kheej-leveling mortar, txo lub sij hawm sinking, txo nws cov drying shrinkage tus nqi, thiab tsis txhob muaj teeb meem xws li tawg thiab drumming ntawm phab ntsa thiab pem teb.
3. Tiv thaiv los ntshav, nws tuaj yeem ua lub luag haujlwm zoo dua hauv kev ncua, tiv thaiv cov slurry los ntawm sedimentation thiab kev ua haujlwm los ntshav zoo dua.
4. Ua haujlwm zoo txaus, qhov viscosity tsawgHydroxypropyl methylcellulose yog tsim los ntawm cov tshuajyuav tsis cuam tshuam rau kev khiav ntawm slurry, kev tsim kho yooj yim, tshwj xeeb cov dej tuav tau zoo, tuaj yeem tsim cov nyhuv zoo tom qab nws tus kheej-leveling, thiab tsis txhob tawg nyob rau hauv cov ntaub ntawv ntawm cov nruas, ruaj khov kev ua tau zoo ntawm cellulose ether tag nrho guarantees zoo fluidity thiab self-leveling muaj peev xwm. Kev tswj cov dej tuav tus nqi tuaj yeem ua rau nws ruaj khov sai thiab txo qis shrinkage thiab tawg.
