Синтез кремнеземного наполнителя на основе отхода карагандинского кремниевого завода

Abstract

This work is devoted to the synthesis of the silica filler- fumed silica based on various liquid glass (sodium and potassium) for further out of the use in the rubber industry. We obtained water glass was heated to 70 degrees with constant stirring. Selection by us revealed that for every 50 ml needed water glass 5 ml of hydrochloric acid to precipitate a white termination loss - white carbon. The hallmark of this study is that the raw material for fumed silica is a waste of Karaganda silicon plant - microsilica does not require energy - costs compared to analogical ways.
