Masonry, plaster thiab tshuaj khib
COV LUS TXWV TXAWV DAIM DAG DIAGRAM
Masonry thiab plastering tshuaj khib yog qhov tseem ceeb tshaj plaws ntawm kev lag luam kev ua lag luam hauv tsev, cellulose ether ua lub luag haujlwm tseem ceeb. Lub khib nyiab zoo yuav tsum muaj cov khoom siv zoo thiab yooj yim rau kev siv, du thiab tsis-txhav riam, sijhawm ua haujlwm zoo, yooj yim rau theem; hauv kev tsim kho tshuab cug yuav tsum ua kom zoo txaus kom yooj yim rau kev thov, du thiab tsis-riam riam, sijhawm ua haujlwm zoo, yooj yim rau theem; hauv kev tsim kho tshuab cug yuav tsum ua kom zoo txaus rau kev thov, du thiab tsis-riam riam, yooj yim rau theem; hauv kev tsim kho tshuab cug yuav tsum ua kom zoo txaus rau kev thov, du thiab tsis-riam riam, yooj yim rau theem; hauv kev tsim kho lub tshuab cug yuav tsum ua kom zoo txaus rau qib Kev tsim kho niaj hnub no, tshuaj khib yuav tsum tseem muaj cov twj tso kua mis zoo kom tsis txhob muaj qhov phom sij rau kev sib tsoo thiab cov yeeb nkab txhaws. Mortar hardened lub cev yuav tsum muaj lub zog zoo thiab lub ntsej muag zoo nkauj, tsim nyog compressive zog, kav ntev, tsis muaj qhov khoob nruas, tsis muaj qhov tawg.
Max cellulose ether dej cia cov khoom ua kom tsis txhob muaj dej nqus los ntawm cov chaw ua haujlwm ntau chaw, txhawb txoj kev muaj dej kom zoo dua ntawm cov khoom siv gel, hauv thaj chaw loj ntawm kev tsim kho. Nws tuaj yeem txo qhov tshwm sim ntawm qhuav ntawm cov tshuaj khib thaum ntxov thiab txhim kho qhov kev sib zog; nws txoj kev ua kom tuab tuaj yeem txhim kho txoj phuam ntub ntawm lub tsho khuam ntub mus rau qhov chaw puag. Cellulose ether ua kom lub ntsej muag ntub dej ntub, thiab txo qis lossis zam kom tsis muaj qhov paug thiab dej tso pa tawm. Rheology thiab txo tsis kam, yog li nce pumpability thiab txo kev siv zog. Hloov kho cellulose ethers muab tsis tuaj yeem tiv thaiv kev tiv thaiv thaum ua cov hmoov av tuab, uas tuaj yeem txo lub sijhawm tsim kho thiab txo cov khib nyiab.
Ntub dej tshuaj khib
KEV TSO CUA SOV KEV TSO CAI RAU QHOB
Ntub dej cug yog qhov sib xyaw ntawm cov cement, zoo sib xyaw ua ke, admixture (feem ntau cellulose ether), dej thiab ntau yam sib xyaw tau txiav txim siab raws li cov khoom, raws li qee qhov sib piv, tom qab ntsuas thiab sib xyaw hauv cov nroj tsuag sib tov, thiab tom qab ntawd thauj mus rau qhov chaw ntawm siv los ntawm kev sib xyaw cov tsheb thauj khoom, muab tso rau hauv cov thawv tshwj xeeb rau kev khaws cia, thiab siv nyob rau hauv ib lub sijhawm.

COV LUS TXWV TXAWV DAIM DAG DIAGRAM
Muab piv rau cov tsoos xaib sib xyaw ua ke, qhov sib txawv loj tshaj plaws yog kev qhia ntawm tshuab caws pliav, xws li kev qhia ntawm cov koob ntawm cov kab mob Max cellulose ether tuaj yeem yog cov admixture uas ua kom zoo dua ntawm cov tshuaj khib ua kom zoo, yog li ua cov tshuaj khib tshiab kom yooj yim, qhov dej siab ceev tus nqi, qhov ntev nyob deb, qhov siab siab tom qab nqus tseem Nws tau ua haujlwm zoo. Nws qhov zoo tshaj plaws yog qhov siab tsim kho qhov ua tau zoo, qhov zoo ntawm lub tshuaj khib tom qab sib sau, thiab vim qhov pib loj sai ntawm lub cug thaum txau. Yog li ntawd, nws tuaj yeem muaj ntau txoj kev ruaj ntseg dua nrog lub hauv qab, uas tuaj yeem txo qhov tshwm sim ntawm hollow nruas tawg.
