Problems solved by technology

[0002] At present, there are many lightweight solid wall materials in my country's domestic market. Although the weight of these wall materials has been reduced, they will be affected by the reduction in wall density in terms of fire prevention, moisture resistance, nail hanging, sound insulation, and impact resistance. However, the performance cannot meet the requirements of use, and the lighter the weight, the greater the impact. In addition, the production cost and environmental protection problems cannot be properly resolved. Therefore, the development of low-cost new environmental protection and energy-saving wall materials is the current top priority.
