In the metal carved plate, the so-called A grade means the non-combustible material, wherein the inorganic material (ie cement) is the A grade, the inorganic fireproof insulation board is used for the insulation material of the wall, instead of the red brick, the thickness of the wall is thinned. Energy conservation is even more powerful, and indirectly expands the building area and reduces the building's own weight. It is both a thermal insulation material and a cold insulation material. However, the existing building exterior insulation materials in the market in China are mainly organic materials. Even with the addition of flame retardants, the highest level can only reach the B1 level.

If the strictest fire-fighting order in history is to be strictly enforced, it means that China's insulation materials industry will face a situation of shuffling or even elimination. Therefore, for some time, the industry's call for revision of the standards for exterior insulation products is quite high.

According to the meeting of the work symposium prepared according to the development of safety and environmental protection exterior wall insulation materials industry and industry access conditions, the new generation of metal engraved sheet materials should be safe and environmentally friendly materials, and should meet three conditions:

1. The first is that the material production process is safe and environmentally friendly, and it can neither cause direct harm nor bury hidden dangers to the safe and healthy environment;

2. The second is that the material has high intrinsic safety, and it is not easy to cause safety hazards in the aspects of storage, transportation, operation, use and disposal, and it is difficult to cause secondary disasters;

3. The third is the further improvement of material consumption, energy consumption, waste discharge and treatment, impact on ecological environment and climate, and comprehensive cost of materials over the life cycle.

People in the industry believe that “hard to avoid safety hazard” is essentially different from “no safety hazard”. The Ministry of Industry and Information Technology has made the industry of insulation materials see a vitality. The manufacturers of insulation materials must also transform their investment into new environmentally friendly building materials. industry.
