Synthetic armorphous silica rau number case, painting thiab txheej
Synthetic armorphous silica (precipitated silica) feem ntau hu ua silica, kuj hu ua hydrated silicic acid, lub teeb silica, tshuaj qhia yog feem ntau sau ib daim ntawv raws li mSiO2 · nH2O, cov tsos ntawm cov dawb siab dispersion ntawm amorphous hmoov, tab sis kuj ua rau hauv granular li ib tug khoom muag . Kev ntiajteb txawj nqus ntawm 2,319 ~ 2,653, lub melting point ntawm 1750 ℃. Tsis txhob yaj nyob rau hauv dej thiab feem coob ntawm cov acids, .Nws yuav polymerize nyob rau hauv cov huab cua tom qab lub haum ntawm cov dej. Soluble nyob rau hauv caustic dej qab zib thiab hydrofluoric acid. Ruaj rau lwm yam tshuaj, kub tsis decompose, tsis txhob hlawv. Muaj ib tug high hluav taws xob rwb thaiv tsev, ntxeem tau, loj deg hauv cheeb tsam, ib tug dej haum, uas tsis yog-tshuaj lom.
