Supply: Wuhan, foam glass, glass Wuhan, Wuhan cement foam board, foam cement board Wuhan foam glass was first invented by the U.S. 彼兹堡康宁 is determined by broken glass, blowing agents, modified additives and foaming promoting agent, after fine grinding and uniformly mixed, and then through high temperature melting, foaming, annealed glass made of inorganic non-metallic materials. It is composed of a large diameter of 1 to 2 mm a uniform bubble structure. Wherein the sound-absorbing foam glass is 50% or more open cells, heat-insulating foam glass is 75% or more of the closed cell, product density of 160-220 kg / m, according to the requirements of use, by producing changes in technical parameters to be adjusted . Because of this new material with moisture, fire, corrosion effect, combined with glass material has a long-term performance does not deteriorate the advantage, so that in adiabatic, cryogenic, underground, open-air, flammable, tidal and other harsh environment of chemical erosion Next greatly favored customers. Is widely used in wall insulation, petroleum, chemical, room noise, sound-absorbing wall highways, electricity, military products, the user called green type insulation. Foam glass from the broken glass, foaming agents, additives and the modified foam promoting agent, after fine grinding and uniformly mixed, and then through high temperature melting, foaming, annealed glass made of inorganic non-metallic materials. Has superior insulation (cold), sound absorption, moisture-proof, fireproof, lightweight, high strength and other characteristics. Advantages: 1, itself non-toxic, non-radioactive, does not release harmful substances, does not pollute the ground and groundwater for environmental-friendly materials; 2, no burning, moisture absorption and low water absorption, temperature range, the actual use of ordinary foam glass temperature of 240 ~ 280 ℃; 3, difficult to weathering, aging, from rat gnawing bites and microbial corrosion; 4, you can change the formula and foaming process, regulating bulk density, open pores and closed porosity and other properties.
