Starch etherFeem ntau yog siv rau 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).
Lub luag haujlwm tseem ceeb
(1) Zoo ceev thickening peev xwm: nruab nrab viscosity, siab dej tuav;
(2) Qhov ntau npaum li cas me me, thiab qhov qis dua tuaj yeem muaj txiaj ntsig zoo;
(3) Txhim kho lub peev xwm los tiv thaiv sag ntawm cov khoom nws tus kheej;
(4) Nws muaj lubricity zoo, uas tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom siv thiab ua rau kev ua haujlwm smoother.
Mib nta
Cov yam ntxwv ntawm cov hmoov txhuv nplej siab ether feem ntau nyob hauv:
(a) Txhim kho sag kuj;
(b) Txhim kho kev tsim kho;
(c) Txhim kho cov dej tuav tus nqi ntawm mortar.
Synergy
Starch ether feem ntau yog siv ua ke nrog methyl cellulose ether, uas qhia tau hais tias muaj txiaj ntsig zoo ntawm ob qho tib si.Ntxiv qhov tsim nyog ntawm cov hmoov txhuv nplej siab ether rau methyl cellulose ether tuaj yeem txhim kho qhov sag resistance thiab slip resistance ntawm mortar.Tus nqi siab dua.
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 tshuaj khib 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 tshuaj ntxiv hauv cov hmoov qhuav mortar, dav siv hauv cov nplais nplaum, kho cov tshuaj khib nyiab, 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 yog tsim rau txhua yam (cement, gypsum, txiv qaub calcium-raws li) sab hauv thiab sab nrauv phab ntsa putty, thiab ntau hom kev mortar plastering mortar.
Nws tuaj yeem siv los ua cov khoom sib xyaw rau cov khoom siv cement, cov khoom siv gypsum thiab cov khoom txiv qaub-calcium.Cov hmoov txhuv nplej siab ether muaj kev sib raug zoo nrog lwm cov kev tsim kho thiab cov khoom sib xyaw;Nws yog qhov tsim nyog rau kev tsim cov khoom sib xyaw qhuav xws li mortar, adhesives, plastering thiab dov cov ntaub ntawv.Starch ether thiab methyl cellulose ether (KimaCellMC qib) yog siv ua ke hauv kev tsim vaj tsev sib xyaw kom sib xyaw kom tuab dua, cov qauv muaj zog, sag kuj thiab yooj yim ntawm kev tuav.Lub viscosity ntawm mortars, adhesives, plasters thiab yob renders uas muaj ntau dua methyl cellulose ethers yuav txo tau los ntawm kev ntxiv ntawm starch ethers.
