Starch ether
Siv ua ke nrog methyl cellulose ether, nws qhia tau hais tias muaj kev sib koom ua ke zoo ntawm ob. Ntxiv qhov tsim nyog ntawm cov hmoov txhuv nplej siab ether rau methyl cellulose ether tuaj yeem txhim kho qhov sag kuj thiab plam tsis kam ntawm mortar, thiab muaj txiaj ntsig zoo.
Nyob rau hauv lub mortar uas muaj methyl cellulose ether, ntxiv ib qho tsim nyog cov hmoov txhuv nplej siab ether tuaj yeem ua rau kom muaj qhov sib xws ntawm cov mortar thiab txhim kho cov dej ntws, ua rau kev tsim kho smoother thiab scraping smoother.
Hauv mortar uas muaj methyl cellulose ether, ntxiv cov hmoov txhuv nplej siab ether uas tsim nyog tuaj yeem ua rau kom cov dej tuav ntawm cov tshuaj khib thiab ua kom lub sijhawm qhib.
Cov hmoov txhuv nplej siab ether yog cov tshuaj hloov pauv cov hmoov txhuv nplej siab ether soluble hauv dej, sib xws nrog lwm cov khoom ntxiv hauv cov hmoov qhuav mortar, dav siv hauv cov nplais nplaum, kho cov tshuaj khib, plaster plaster, sab hauv thiab sab nrauv phab ntsa putty, gypsum-raws li caulking thiab sau cov ntaub ntawv, cov neeg ua haujlwm sib txuas, masonry mortar.
Cov hmoov txhuv nplej siab ether feem ntau yog siv hauv kev tsim mortar, uas tuaj yeem cuam tshuam qhov sib xws ntawm mortar raws li gypsum, cement thiab txiv qaub, thiab hloov kev tsim kho thiab sag kuj ntawm mortar. Cov hmoov txhuv nplej siab ethers feem ntau yog siv ua ke nrog cov tsis hloov pauv thiab hloov kho cellulose ethers. Nws yog haum rau ob qho tib si nruab nrab thiab alkaline systems, thiab yog sib xws nrog feem ntau additives nyob rau hauv gypsum thiab cement khoom (xws li surfactants, MC, starch thiab dej-soluble polymers xws li polyvinyl acetate).
Cov yam ntxwv ntawm cov hmoov txhuv nplej siab ether feem ntau nyob hauv:
⑴ Txhim kho sag kuj;
⑵ Txhim kho kev tsim kho;
⑶ Txhim kho cov dej tuav tus nqi ntawm mortar
