The production of foam glass block principle
Foam glass block was first invented by the United States Pittsburgh Corning company, is broken glass, foaming agent, modified additives and foam accelerator, etc., after fine grinding and even mixing, and then after high temperature melting, foaming, annealing Into the inorganic non-metallic glass material. It consists of a large number of 1 to 2 mm in diameter uniform bubble structure. Which absorbs foam glass block for more than 50% of the pores, adiabatic foam glass for more than 75% of the closed-cell bubbles, according to the use of the requirements, through the production of technical parameters to adjust.
Because of this new material with moisture, fire, anti-corrosion effect, coupled with the long-term use of glass material does not degrade the advantages of its adiabatic, cryogenic, underground, open air, flammable, tide and chemical erosion and other harsh environments Favored by users. It is widely used in wall insulation, petroleum, chemical, engine room noise reduction, expressway sound-absorbing wall, electricity, military products, etc., by the user called green environment-friendly insulation materials.
According to the various properties of foam glass block , it can be used as a heat insulation material in various parts of the construction project, but also for shipbuilding, chemical, low temperature and high temperature technology. White and stained glass are also used for sound and decorative materials. The waste in production - foam glass block powder and scrap can also be used as a filler for decorative light concrete and other uses. According to the use of different, the use of the corresponding process of production of foam glass products can be divided into four categories, namely, thermal insulation foam glass, sound-absorbing decorative foam glass, decorative foam glass and granular foam glass.
