Foam glass is a kind of hard heat insulating material. It is a kind of uniform independent closed gas which is made of ground glass powder as the main raw material, added by foaming agent, sintered and foamed, and annealed and cooled. A novel inorganic insulation material with a gap structure.
Foam glass is the only material for low temperature insulation at home and abroad. It has low bulk density, low thermal conductivity, no moisture permeability, no water absorption, no combustion, no mildew, high mechanical strength, but easy processing, chemical corrosion resistance other than hydrogen fluoride, non-toxic, chemically stable, and capable of It is used in a wide temperature range from ultra-low temperature to high temperature (-268°C--+482°C).
At the same time, its important value is not only good thermal insulation performance that will not deteriorate for many years, but also plays a role in fire prevention and shock resistance. It is not only safe and reliable, but also durable in the harsh environment of low temperature, deep cooling, underground, open air, flammable, damp and chemical attack. It is called “permanent insulation material without replacementâ€. Therefore, it is widely used in the insulation and cold preservation of permanent projects such as petroleum, chemical, cold storage, underground engineering, shipbuilding, and national defense.
