Thaum nws los txog rau mortar daim ntaub ntawv, ua kom pom kev ua haujlwm tau zoo yog qhov tseem ceeb rau kev tsim kho kom zoo.Ib qho khoom tseem ceeb uas tuaj yeem txhim kho kev ua haujlwm tau zoo yog MHEC (Methyl Hydroxyethyl Cellulose).Hauv tsab xov xwm no, peb yuav qhia txog qhov ua tau zoo ntawm kev siv MHEC los ua tus tswv daim ntawv thov mortar thiab qhib nws lub peev xwm tag nrho.
Nkag siab MHEC:
MHEC yog cellulose-raws li additives uas ua raws li dej-retaining tus neeg sawv cev nyob rau hauv mortar.Nws cov khoom tshwj xeeb ua rau nws tiv thaiv kom tsis txhob ntxov ntxov evaporation thiab nqus dej noo hauv cov khib nyiab ntub dej.Los ntawm khaws cov dej, MHEC ncua cov txheej txheem dej ntawm cov cement, ncua lub sijhawm ua haujlwm ntawm cov tshuaj khib nyiab.
Cov txiaj ntsig ntawm MHEC hauv Mortar Applications:
ib.Lub Sijhawm Ua Haujlwm Txuas Ntxiv: MHEC tso cai rau lub sijhawm ua haujlwm ntev dua, ua rau daim ntawv thov ntawm txheej txheej mortar, du plastering, thiab tshem tawm qhov xav tau ua ntej wetting ntawm absorbent substrates.
b.Txhim kho Plasticity: Qhov sib ntxiv ntawm MHEC rau mortar txhim kho nws cov yas, ua kom yooj yim sib xyaw, sib kis, thiab zoo li qub.Qhov no txhim kho kev ua haujlwm tag nrho thiab kev ua haujlwm ntawm kev siv.
c.Tswj Lub Sijhawm Teeb Meem: MHEC ua raws li tus neeg thim rov qab, kho lub sijhawm teeb tsa ntawm cov mortar tshiab.Qhov kev tswj hwm no tso cai rau kev hloov pauv tau zoo dua thiab hloov kho thaum lub sijhawm tsim kho, ua kom cov txiaj ntsig zoo.
Cov tswv yim siv tswv yim:
ib.Kev Siv Kom Zoo: Nws yog ib qho tseem ceeb los txiav txim siab qhov tsim nyog npaum li cas ntawm MHEC raws li qhov xav tau ntawm kev ua haujlwm thiab cov haujlwm tshwj xeeb.Ua raws li cov chaw tsim khoom cov lus qhia thiab ua cov kev sim me me kom kho qhov ntau npaum li cas.
b.Cov txheej txheem sib xyaw: Ntxiv MHEC rau cov mortar qhuav maj mam thaum sib tov, kom ntseeg tau tias muaj kev sib cais.Nws raug nquahu kom siv cov khoom sib tov zoo kom ua tiav homogeneous sib xyaw.
c.Ntxiv dej: Kho cov ntsiab lus dej raws li cov neeg tsim khoom pom zoo thiab qhov xav tau sib xws.MHEC cov dej tuav cov khoom pab tswj cov mortar cov dej noo, txo qhov kev pheej hmoo ntawm kev ziab ntxov ntxov.
d.Daim Ntawv Thov Kev Siv: Siv lub sijhawm ua haujlwm txuas ntxiv los ntawm MHEC kom ua tib zoo siv cov mortar.Smooth thiab zoo li lub mortar raws li xav tau, kom ntseeg tau tias txawm tias kev pab them nqi thiab adhesion kom raug.
MHEC hauv Real-Life Projects:
Qhia txog cov haujlwm ua tau zoo uas MHEC tau siv los ua kom tau txais kev ua haujlwm tau zoo, qhia txog kev txhim kho kev ua haujlwm, txo qis rov ua haujlwm, thiab txhim kho kev tsim kho tag nrho.Sib tham txog cov teeb meem tshwj xeeb tau ntsib thiab yuav ua li cas MHEC pab kov yeej lawv.
Mastering mortar daim ntawv thov yuav tsum muaj kev nkag siab zoo ntawm cov khoom xyaw siv.Los ntawm kev koom ua ke MHEC rau hauv cov khoom sib tov sib xyaw, cov neeg cog lus tuaj yeem ua tiav kev ua haujlwm zoo, txhim kho cov yas, thiab kev tswj xyuas zoo dua rau lub sijhawm.Raws li kev tsim kho kev xav tau nce ntxiv, kev siv lub zog ntawm MHEC yog qhov tseem ceeb rau kev ua tiav qhov project.Txais MHEC cov khoom tuav dej, thiab qhib nws lub peev xwm los coj koj cov ntaub ntawv mortar mus rau qib tom ntej ntawm kev ua tau zoo.
