Problems solved by technology

[0002] With the rapid development of the national economy and the continuous improvement of people's living standards, the consumption of energy is also increasing, and the problem of energy shortage is becoming more and more prominent. Therefore, people pay more and more attention to energy-saving and environmentally friendly building materials. It is widely used. Usually, the lower insulation brick is made of sawdust, polylight ball, kaolin, bauxite clinker, etc., but the cost of the above-mentioned raw materials is relatively high, and the sintering temperature is high in the process of preparing refractory insulation brick. From Another aspect increases the processing cost
Moreover, the demand for low-density refractory bricks in industrial production is increasing, and the requirements for the compressive strength of low-density products are also getting higher and higher. The compressive strength must be above 1.5MPa. However, the low-density refractory bricks currently on the market The above compressive strength cannot be achieved, seriously affecting the reliability and safety of construction projects
