Precipitated Silica rau Txheej
Precipitated silica, feem ntau hu ua dawb carbon dub, tseem hu ua hydrated silicic acid, lub teeb silica, chemical expressionis feem ntau sau li mSiO2 • nH2O, cov tsos ntawm cov dawb heev dispersed amorphous hmoov, kuj ua tiav rau hauv pellets ua khoom muag. Qhov tshwj xeeb lub ntiajteb txawj nqus yog 2.319 ~ 2.653, thiab lub melting point yog 1750 degree.
Precipitated silica yog ib qho tseem ceebadditives nyob rau hauv cov tshuaj txhuam hniav. Nws plays ob lub luag haujlwm hauv tshuaj txhuam hniav. Ib qho yog cov nyhuv ntawm kev sib txhuam tus neeg sawv cev thiab lwm qhov yog cov thickener. Cov silica ua los ntawm txoj kev nag lossis daus muaj qhov loj tag nrho thaj chaw tshwj xeeb, muaj zog adsorption muaj peev xwm, cov khoom me me, cov khoom siv kho qhov muag zoo rau kev txhim kho pob tshab, qhov ruaj khov, tsis muaj tshuaj lom thiab tsis muaj mob, thiab yog cov tshuaj txhuam hniav zoo.
