Cellulose ether rau Cov Tshuaj Sib Xyaws Tus Kheej
Cov tshuaj mortar uas nws tus kheej leveling yog ib yam khoom siv thev naus laus zis siab heev uas muaj cov ntsiab lus thev naus laus zis siab thiab cov kev sib txuas lus nyuaj. Nws yog cov khoom siv hmoov qhuav sib xyaw ua ke ntawm ntau yam khoom xyaw, uas tuaj yeem siv los ntawm kev sib tov dej ntawm qhov chaw. Tom qab nthuav me ntsis ntawm lub scraper, koj tuaj yeem tau txais qib siab ntawm qhov chaw. Cov cement uas nws tus kheej leveling muaj qhov ceev ceev hardening. Nws tuaj yeem taug kev tom qab 4-5 teev, thiab kev tsim kho nto (xws li pem teb ntoo, pob zeb diamond, thiab lwm yam) tuaj yeem ua tiav tom qab 24 teev. Kev tsim kho sai thiab yooj yim tsis muaj qhov sib piv los ntawm kev siv tes leveling ib txwm muaj.
Cov cement/mortar uas ua rau nws tus kheej tiaj tus yog ib hom pem teb tiaj tus thiab du uas tuaj yeem muab tso rau nrog cov txheej tiav kawg (xws li cov ntaub pua plag, pem teb ntoo, thiab lwm yam). Nws cov kev cai tseem ceeb rau kev ua haujlwm suav nrog kev tawv sai thiab tsis tshua ntsws. Muaj ntau hom pem teb sib txawv hauv khw, xws li cov cement, gypsum lossis lawv cov khoom sib xyaw.
Cov khoom siv tseem ceeb ntawm cov cement/mortar uas siv tau rau tus kheej
(1) Kev Siv Nyiaj Tau Los
Kev nploov pauv yog ib qho cim qhia tseem ceeb uas qhia txog kev ua tau zoo ntawm cov cement/mortar uas nws tus kheej ua kom tiaj tus. Feem ntau, qhov nploov pauv yog ntau dua 210 ～ 260 hli.
(2) Kev ruaj khov ntawm cov slurry
Cov ntsuas no qhia txog kev ruaj khov ntawm cov cement/mortar uas nws tus kheej leveled. Muab cov slurry sib xyaw rau ntawm lub phaj iav uas tso kab rov tav, thiab saib tom qab 20 feeb. Yuav tsum tsis muaj qhov pom tseeb ntawm kev los ntshav, kev tawg, kev sib cais, lossis kev tig ntawm cov npuas dej. Cov ntsuas no muaj feem cuam tshuam ntau dua rau qhov xwm txheej ntawm qhov chaw thiab kev ruaj khov ntawm cov khoom tom qab molding.
(3) Lub zog compressive
Ua ib yam khoom siv hauv pem teb, qhov ntsuas no yuav tsum ua tau raws li cov lus qhia txog kev tsim kho rau cov plag tsev cement. Cov plag tsev cement mortar hauv tsev xav tau lub zog compressive ntawm 15MPa lossis ntau dua, thiab lub zog compressive ntawm cov txheej cement concrete yog 20MPa lossis ntau dua.
(4) Lub zog khoov
Lub zog flexural ntawm kev lag luam tus kheej-leveling cement / mortar yuav tsum ntau dua 6Mpa.
(5) Lub sijhawm teem tseg
Rau lub sijhawm teeb tsa ntawm cov cement / mortar uas nws tus kheej ua kom sib npaug, tom qab paub tseeb tias cov slurry sib xyaw sib npaug, xyuas kom meej tias nws siv sijhawm ntau dua 40 feeb, thiab kev ua haujlwm yuav tsis raug cuam tshuam.
(6) Kev cuam tshuam tsis kam
Cov cement/mortar uas nws tus kheej leveled yuav tsum muaj peev xwm tiv taus kev sib tsoo los ntawm kev tsheb khiav ib txwm thiab cov khoom thauj, thiab qhov kev tiv thaiv ntawm av yuav tsum ntau dua lossis sib npaug rau 4 joules.
(7) Hnav tsis kam
Cov cement/mortar uas siv tau rau hauv av yog siv los ua cov khoom siv rau hauv av thiab yuav tsum tiv taus kev khiav hauv av ib txwm muaj. Vim nws ntws zoo.
Cov txheej tiaj tiaj yog nyias, thiab thaum lub hauv paus hauv av khov kho, nws lub zog feem ntau yog nyob rau ntawm qhov chaw, tsis yog nyob rau ntawm qhov ntim. Yog li ntawd, nws qhov kev tiv thaiv kev hnav yog qhov tseem ceeb dua nws lub zog compressive.
(8) Kev sib txuas lub zog tensile rau txheej hauv paus
Lub zog sib txuas ntawm cov cement/mortar uas ua rau nws tus kheej thiab cov txheej hauv paus yog ncaj qha cuam tshuam nrog seb cov slurry puas yuav raug hollowed thiab tev tawm tom qab hardening, uas muaj kev cuam tshuam ntau dua rau qhov ruaj khov ntawm cov khoom siv. Hauv cov txheej txheem kev tsim kho tiag tiag, pleev xim rau tus neeg sawv cev hauv av kom nws mus txog qhov xwm txheej uas tsim nyog dua rau kev tsim cov khoom siv uas ua rau nws tus kheej. Lub zog tensile ntawm cov cement hauv tsev cov khoom siv uas ua rau nws tus kheej feem ntau yog siab dua 0.8MPa.
(9) Tiv thaiv kev tawg
Kev tiv thaiv kab nrib pleb yog ib qho cim tseem ceeb ntawm cov cement/mortar uas nws tus kheej leveling, thiab nws qhov loj me yog cuam tshuam nrog seb cov khoom siv uas nws tus kheej leveling puas muaj kab nrib pleb, qhov khoob, thiab qhov poob tom qab hardening. Kev ntsuam xyuas kom raug ntawm kev tiv thaiv kab nrib pleb ntawm cov khoom siv uas nws tus kheej leveling yog cuam tshuam nrog kev ntsuam xyuas kom raug ntawm kev ua tiav lossis kev ua tsis tiav ntawm cov khoom siv uas nws tus kheej leveling.
