Vacuum heat insulation board is a kind of vacuum insulation material, which is composed of filling core material and vacuum protective surface. The product has low thermal conductivity, environmental protection and energy-saving characteristics. Under the same insulation requirements, the vacuum insulation board has the advantages of thin thickness, small volume and light weight. Vacuum heat insulation board requires the core material itself low thermal conductivity, non-combustible, a certain strength, stable performance. There are two kinds of glass fiber and gas silicon for selection.

Glass fiber has the advantages of light constitution, low thermal conductivity, thermal insulation and sound absorption, and is an ideal core material. But the vacuum heat insulation board made of this core material, once the loss of vacuum degree after the expansion rate of the plate reaches more than 80%, if applied to the building will bring great safety risks.

The gas phase silica not only has the same advantages of glass fiber, and the vacuum insulation board made of gas phase silica is very stable, even after vacuum failure, the expansion rate is below 5%. At the same time, the gaseous silica itself has a strong activity, can be in the process of use may penetrate into the plate trace water vapor adsorption, so that the vacuum insulation board has a longer service life.

The core material of vacuum adiabatic plate is mainly adiabatic material, which greatly reduces the heat transfer caused by heat conduction. The vacuum encapsulation technology reduces the air content inside the material, which can effectively avoid the heat transfer caused by air convection. Special COMPOSITE gas barrier film is made of metal aluminum foil film, nano glass fiber polymerization film, special binder and other main materials, made of thermal bonding technology, wherein the metal aluminum foil film can reflect 70%-90% radiant heat.
