Set for production of thermal insulating foam glass using the wet method using a glass recycling cullet

摘要

black glass foam produced in the heat treatment process using glass powder and additive, glycerine and coal dust as a measure spieniaju0105cego, characterised by the fact that glass powder has a fineness of less than 100? m and the following chemical composition in percentage by weight: sio2 62u00f775; al2o3 1u00f75; cao 4u00f78 2u00f73,5; mgo; na2o k2o 11u00f717; 0.1 - 3; so2 0.2 - 0.6.the invention also includes the method of black glass foam, which is characterised by that the glass powder is subjected to the chemical activation by the solution of potassium nitrate kno3 and / or alternatively sodium nitrate nano3 with added dust charcoal or coal in the acetone in the quantity 6u00f712 percent by weight.
