Glass Foam; Advantages, Applications and Production

Although glass foam is non-known product in Iran but it was produced in United State of America around 80 years ago. Already glass foam is use in wide range of construction and Industries in developed countries.Glass foam has variety of advantages as; very good insulating material for heat, noise and humidity, high compressive resistance, light weight with low density, passive fire protection as incombustible product, no water absorption, dimension stability, chemical resistance with all chemical (except HF), easy work with simple tools like hand saw and finally ecological product because could produce by waste glass and could also reused as filler in thermal insulation material or as gravel in the road or roof.Also with above wide range of advantages, it has also application in many of Industries, power plant and construction. To produce glass foam, it should be start from waste glass and grind it to clear particle size. Then it should be add the foaming agent and mix it carefully. finally it should be transferred to big steel mould and put in the kiln tunnel and heat up to 850 centigrade degree with special heating carve. At the exit of kiln glass foam in big block will be ready. This big block will cut and saw in standard sizes and packed.Total value of investment for 30000 cubic meters per year is around 11 to 12 million Euros.
