Kind of foam glass waste as a raw material of foam glass production process

The present invention discloses a foam glass waste as a raw material of foam glass production process, comprising the steps of: after the mixing of raw materials, followed by milling, compression molding, foaming, annealing, to obtain a foam glass, parts by weight of the material of the following composition : 90 ~ 95 foam glass waste; foaming agent from 0.1 to 0.3; flux 3 to 7; particle size milled powder obtained is 80 ~ 120μm; foaming process the temperature controller were as follows: 20 ~ 35 ℃ / min rate of temperature rise to 400 ~ 450 ℃, then warmed to 700 ~ 750 ℃ ​​at a rate of 5 ~ 10 ℃ / min, and then at 2 ~ 4 ℃ min the temperature was raised to 830 ~ 900 ℃ /, and the thermostat 30 to 60 minutes to complete foam. The present invention not only waste glass foam timely and effective treatment, saving production costs, while the resulting foam glass was prepared with good performance.
