Cellulose ether rau Self-leveling Compounds
Self-leveling mortar yog cov khoom siv hluav taws xob ib puag ncig tiv thaiv nrog cov ntsiab lus thev naus laus zis thiab cov kev sib txuas nyuaj. Nws yog cov khoom siv hmoov sib xyaw qhuav uas muaj ntau yam khoom xyaw, uas tuaj yeem siv los ntawm kev sib xyaw dej ntawm qhov chaw. Tom qab me ntsis kis ntawm scraper, koj tuaj yeem tau txais qib siab ntawm lub hauv paus nto. Self-leveling cement muaj ib tug ceev hardening ceev. Nws tuaj yeem taug kev tom qab 4-5 teev, thiab kev tsim kho saum npoo (xws li hauv pem teb ntoo, pob zeb diamond board, thiab lwm yam) tuaj yeem nqa tawm tom qab 24 teev. Kev tsim kho sai thiab yooj yim yog unmatched los ntawm ib txwm phau ntawv leveling.
Self-leveling cement / mortar yog ib hom tiaj tiaj thiab du hauv pem teb uas tuaj yeem muab tso nrog txheej txheej kawg (xws li ntaub pua plag, ntoo pem teb, thiab lwm yam). Nws cov kev ua haujlwm tseem ceeb suav nrog kev ua kom nrawm nrawm thiab qis qis. Muaj cov txheej txheem hauv pem teb sib txawv ntawm kev ua lag luam, xws li cement-based, gypsum-based lossis lawv cov khoom sib tov.
Cov khoom tseem ceeb ntawm tus kheej-leveling cement / mortar
(1) Liquidity
Fluidity yog ib qho tseem ceeb qhia txog kev ua haujlwm ntawm tus kheej-leveling cement / mortar. Feem ntau, qhov fluidity ntau dua 210 ~ 260mm.
(2) Slurry stability
Qhov ntsuas no qhia txog kev ruaj ntseg ntawm tus kheej-leveling cement / mortar. Ncuav cov slurry sib xyaw rau ntawm kab rov tav tso iav phaj, thiab saib tom qab 20 feeb. Yuav tsum tsis muaj qhov pom tseeb los ntshav, delamination, cais, lossis ua npuas. Qhov ntsuas no muaj kev cuam tshuam ntau dua ntawm qhov chaw saum npoo thiab durability ntawm cov khoom tom qab molding.
(3) Compressive zog
Raws li cov khoom siv hauv pem teb, qhov ntsuas no yuav tsum ua kom tau raws li kev tsim kho tshwj xeeb rau cov cement pem teb. Lub hauv paus zoo tib yam cement mortar deg pem teb yuav tsum muaj lub zog compressive ntawm 15MPa lossis ntau dua, thiab lub zog compressive ntawm cement pob zeb txheej txheej yog 20MPa lossis ntau dua.
(4) Flexural zog
Lub zog flexural ntawm kev lag luam tus kheej-leveling cement / mortar yuav tsum siab dua 6Mpa.
(5) Teem sijhawm
Rau lub sijhawm teeb tsa ntawm tus kheej-leveling cement / mortar, tom qab paub meej tias cov slurry sib tov sib xyaw, xyuas kom meej tias nws lub sijhawm siv ntau dua 40 feeb, thiab kev ua haujlwm yuav tsis cuam tshuam.
(6) Kev cuam tshuam tsis kam
Tus kheej-leveling cement / mortar yuav tsum muaj peev xwm tiv thaiv kev sib tsoo los ntawm kev tsheb thiab thauj khoom, thiab qhov cuam tshuam ntawm av yuav tsum siab dua lossis sib npaug li 4 joules.
(7) Hnav tsis kam
Self-leveling cement / mortar yog siv los ua cov khoom siv hauv av thiab yuav tsum tiv taus kev tsheb khiav hauv av. Vim nws ntws
Lub tiaj tiaj yog nyias, thiab thaum lub hauv paus hauv av yog cov khoom, nws cov kabmob quab yuam yog nyob rau saum npoo, tsis yog nyob rau hauv ntim. Yog li ntawd, nws hnav tsis kam yog qhov tseem ceeb tshaj nws lub zog compressive.
(8) Bonding tensile zog rau lub hauv paus txheej
Lub zog sib txuas ntawm tus kheej-leveling cement / mortar thiab lub hauv paus txheej yog ncaj qha ntsig txog seb cov slurry yuav hollowed thiab tev tawm tom qab hardening, uas muaj kev cuam tshuam ntau dua ntawm cov khoom siv. Nyob rau hauv txoj kev tsim kho tiag tiag, pleev xim rau hauv av interface tus neeg sawv cev kom nws ncav cuag qhov xwm txheej zoo dua rau kev tsim cov khoom siv tus kheej. Daim ntawv cog lus tensile lub zog ntawm cov cement pem teb tus kheej-leveling cov ntaub ntawv feem ntau yog siab tshaj 0.8MPa.
(9) Kev tiv thaiv tawg
Crack resistance yog ib qho tseem ceeb qhia ntawm tus kheej-leveling cement / mortar, thiab nws qhov loj me yog cuam tshuam txog seb cov khoom siv tus kheej muaj cov kab nrib pleb, hollows, thiab shedding tom qab hardening. Qhov kev ntsuam xyuas qhov tseeb ntawm qhov tawg tsis kam ntawm tus kheej-leveling cov ntaub ntawv muaj feem xyuam rau qhov tseeb kev ntsuam xyuas ntawm kev vam meej los yog tsis ua hauj lwm ntawm tus kheej-leveling cov ntaub ntawv.
