Thermal insulation material is compared, plank class thermal insulation material is at low cost, it is high-strength it is light, heat insulation effect is good, and can be prefabricated, realize automation
Production；Finished product can cut, is assembled at the scene, and construction efficiency is improved, and in China, in the market, heat preservation plate material is mesh to thermal insulation material
Preceding widely used a kind of thermal insulation material.
External-wall heat-insulation material fire resistance is unquestionable to the importance of building, and traditional organic insulation material fire resistance
The problem of difference, causes its foreground to cause anxiety.Glass bead insulation plate be it is a kind of with glass bead, cementitious material, nemalite suede,
The heat insulating inorganic plate that additive is prepared as a raw material, the thermal insulation board is not only light high-strength, but also prepares, easy construction,
Compared to vitrification micropearl morttar, thermal insulation board can be prefabricated in the factory, and realize that automatic batch production, finished product can cut, spell at the scene
Dress, construction efficiency are improved.But current glass bead insulation plate heat insulating ability is poor, intensity is low, and quality still needs to carry with performance
It is high.
