Hong Kong Dali Company has a joint venture with China to operate a red brick factory in Shenzhen, Shenzhen Special Economic Zone. The red brick produced by the plant is pressed with high pressure to form a common soil-admixed adhesive. Its performance exceeds China’s standard red brick standard. Also has no bending, no shrinkage, smooth and straight surface, waterproof, heat insulation, sound insulation and other properties. As a building material. Its various technical indicators are indeed excellent. The brick has a compressive strength of more than 150kg/cm~2, a water absorption rate of less than 10%, a fire-resistant temperature of 1200°C, a thermal conductivity of 1.76×10~3cal/cm·sec, and an external dimension of 240mm×
