Hydroxypropyl methylcellulose HPMC feem ntau siv hauv ntau qhov kev 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 masonry thiab plastering., Caulking thiab lwm yam kev tsim kho tshuab, tshwj xeeb tshaj yog nyob rau hauv kev tsim kho kom zoo nkauj.Nws feem ntau yog siv rau cov pobzeb pobzeb, marbles, thiab qee cov yas kho kom zoo nkauj.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 cov txheej txheem zoo thiab ci, tsis yooj yim rau tshem tawm cov hmoov, txhim kho cov qib kev ua tau zoo, thiab lwm yam, tshwj xeeb tshaj yog rau daim ntawv thov hauv thaj chaw ntawm lub tsev self-leveling mortar.
Self-leveling mortar feem ntau yog ib tug du thiab tus kheej-compacting peev xwm ntawm tshwj xeeb qhuav mortar khoom, nws tus kheej-compacting, txij li thaum lub peev xwm mus cuag ib tug seamless thiab du nto txheej yog heev tseem ceeb, rau zoo self-leveling khoom, yuav muaj kev ua haujlwm tsim nyog, thiab muaj peev xwm ua tau raws li lub sijhawm tsim kho, tswj nws qhov kev ua tau zoo ntawm tag nrho, thiab kev kho tus kheej muaj peev xwm, yog li, Qhov no yuav tsum tau mortar nyob rau lub sijhawm no kom muaj kev ruaj ntseg thiab zoo ib yam, thiab qhov thib ob, rau mortar tab sis kuj muaj ib qho Qee lub zog, nrog rau cov kabmob muaj peev xwm thiab kev sib khi ntawm lub hauv paus nto, cov no yog cov txheej txheem yooj yim rau cov ntaub ntawv hauv pem teb tuaj yeem siv tau, tus kheej-leveling cov kev siv no, kev ua tau zoo ntawm hydroxypropyl methyl cellulose ether zoo siab txais tos tuaj koom nrog peb, nws tuaj yeem ua. raws li thickening reinforced adhesion, Nws kuj muaj cov yam ntxwv ntawm kev tuav dej siab thiab siv sijhawm ntev.
Qhov siab dua qhov viscosity ntawm hydroxypropyl methyl cellulose yog, qhov zoo dua qhov viscosity ntawm cov ntaub ntawv hloov cement-based yog, tab sis yog tias cov viscosity loj dhau, nws yuav cuam tshuam rau qhov fluidity thiab kev ua haujlwm ntawm cov khoom.Tsis tas li ntawd, cov nyhuv thickening ntawm hydroxypropyl methyl cellulose kuj tuaj yeem ua rau cov dej xav tau ntawm cov ntaub ntawv cement-based, yog li ua rau cov khoom siv khib nyiab.Self-leveling mortar thiab self-compacting pob zeb, uas yuav tsum tau muaj fluidity, yuav tsum tau tsawg viscosity ntawm hydroxypropyl methyl cellulose.Tsis tshua muaj viscosity cellulose ether tuaj yeem ua rau muaj kev cuam tshuam zoo, tuaj yeem tiv thaiv slurry kev sib haum xeeb, kuj muaj kev ua haujlwm ntawm exudation, kuj tuaj yeem xyuas kom meej tias yuav tsis cuam tshuam rau tus kheej-leveling mortar cov khoom ntws, kev tsim kho yooj yim, tab sis kuj muaj cov yam ntxwv ntawm Gao Baoshui, tuaj yeem ua rau saum npoo ntawm cov dej ntws tom qab cov nyhuv zoo dua, txo qhov shrinkage ntawm mortar, tsis txhob tev tawg, thiab lwm yam.
Hydroxypropyl methyl cellulose yog siv dav hauv txhua yam khoom siv hauv tsev.Thaum siv rau hauv tus kheej-leveling mortar, nws muaj cov yam ntxwv hauv qab no:
1, dej tuav kev ua haujlwm siab, tuaj yeem ua kom ntev lub sijhawm ua haujlwm ntawm tus kheej-leveling mortar, txhim kho lub zog ntawm mortar, ua kom nws cov nyiaj ruaj khov, kev ua haujlwm ntub dej zoo, tuaj yeem txo cov av tshauv.
2, lub compatibility yog muaj zog, haum rau txhua yam ntawm lub tsev cov ntaub ntawv, nws tus kheej-leveling mortar, txo lub sij hawm sinking, txo lub qhuav shrinkage tus nqi, kom tsis txhob muaj cov phab ntsa thiab av cracking nruas thiab lwm yam teeb meem.
3, tiv thaiv los ntshav, nws tuaj yeem ua lub luag haujlwm zoo dua hauv kev ncua, tiv thaiv slurry deposition thiab kev ua tau zoo ntawm cov ntshav.
4, khaws cov khoom zoo, tsis tshua muaj viscosity ntawm hydroxypropyl methyl cellulose yuav tsis cuam tshuam rau kev khiav ntawm slurry, kev tsim kho yooj yim, dej tuav tau zoo, tuaj yeem tsim qhov chaw zoo tom qab nws tus kheej leveling nyhuv, tsis txhob tawg ntawm lub nruas, cellulose ether thiab ruaj khov kev ua haujlwm. , tag nrho lav qhov zoo liquidity, raws li zoo raws li lub peev xwm ntawm tus kheej-leveling, Tswj cov dej tuav tus nqi yuav ua rau nws solidify ntau sai thiab txo shrinkage thiab cracking.
