Ethyl silicate CAS 78-10-4 yog dab tsi?

Ethyl silicate tseem hu ua tetraethyl silicate los yog tetraethoxysilane. Cov kua tsis muaj xim thiab pob tshab nrog cov ntxhiab tsw tshwj xeeb. Nws yog ruaj khov nyob rau hauv lub xub ntiag ntawm anhydrous tshuaj, decomposes rau hauv ethanol thiab silicic acid thaum sib cuag nrog dej, ua turbid nyob rau hauv cov huab cua noo, thiab yog soluble nyob rau hauv organic solvents xws li cawv thiab ether. Toxic thiab khaus heev rau lub qhov muag thiab ua pa ib ntsuj av. Nws yog tsim los ntawm distillation tom qab cov tshuaj tiv thaiv ntawm silicon tetrachloride thiab anhydrous ethanol. Nws yog siv los ua cov tshuaj tiv thaiv tshav kub thiab tshuaj tiv thaiv thiab npaj cov kuab tshuaj silicone. Nws kuj tuaj yeem siv rau hauv cov khoom siv organic, ua cov khoom siv raw rau kev npaj cov khoom siv qib siab, ua tus neeg saib xyuas iav kho qhov muag, cov ntaub qhwv, thiab ua cov khoom siv insulating hauv kev lag luam hluav taws xob, thiab lwm yam.

Daim ntawv thov

Ethyl silicate feem ntau yog siv rau hauv cov tshuaj-resistant coatings thiab tshav kub-resistant coatings, silicone solvents thiab precision manufacturing adhesives. Tom qab ua tiav hydrolysis, zoo heev silica hmoov yog tsim, uas yog siv los tsim phosphors thiab kuj siv tau raws li ib tug tshuaj reagent. Tetraethoxysilane feem ntau yog siv rau hauv cov iav kho qhov muag, cov tshuaj tiv thaiv kab mob, cov tshuaj tiv thaiv tshav kub thiab cov nplaum. Kev hloov kho ntawm cov tshuaj tiv thaiv corrosion Crosslinking tus neeg saib xyuas, khi, tus neeg saib xyuas lub cev qhuav dej; Kev tsim cov catalyst skeletons thiab high-purity ultrafine silica. Ethyl orthosilicate feem ntau yog siv rau hauv cov iav kho qhov muag, cov tshuaj tiv thaiv cov tshuaj tiv thaiv, cov txheej txheem kub-resistant thiab cov nplaum. Kev hloov kho ntawm cov tshuaj tiv thaiv corrosion Crosslinking tus neeg saib xyuas, khi, tus neeg saib xyuas lub cev qhuav dej; Kev tsim cov catalyst skeletons thiab high-purity ultrafine silica.
