Application and development of refractory insulation fibre products 2

     Compared with traditional refractory materials, refractory insulation fibre products have superior thermal insulation performance, but their high-temperature compressive strength is low. In order to obtain refractory insulation fibre products with excellent properties such as higher strength and lower thermal conductivity, the following points can be considered:

     1. It is necessary to design a reasonable test idea, after some formula composition tests, change the type and composition of the material, use different binders and addition amounts, analyse the relationship between the material formula, process parameters and the heat insulation effect, and optimize Material formula, confirm the phase and structure of reasonable insulation materials, and develop more superior refractory insulation fibre products.

     2. The key to the refractory insulation fibre products lies in the method of introducing internal pores. Increase the rate of closed bubbles to increase the load capacity under high temperature while improving the thermal insulation effect.

     3. Use suitable multi-phase composite materials to improve the high-temperature thermal insulation performance of the original single-phase materials, such as thermal insulation materials with certain fire resistance, etc., make it both low thermal conductivity and high strength.

     In addition, with the rapid development of science and technology, the continuous progress of human society, people's awareness of self-protection continues to increase, and the selective use of energy-saving materials has become a general trend. The development of light-weight, good thermal insulation performance, low environmental pollution, and long service life thermal insulation materials will become an effective way to save energy. It is believed that the development prospects of refractory insulation fibre products will become more and more broad.
