Compared with traditional refractory materials, although lightweight thermal insulation materials have superior thermal insulation performance, they lack high temperature and pressure resistance. In order to obtain lightweight heat insulation materials with superior properties such as higher strength and lower thermal conductivity, the following points can be considered:
1.Need to design a reasonable test ideas, after a number of formulations of the test, change the type and composition of the material, use different adhesives and amount of addition, explore the relationship between the material formula, process parameters and heat insulation effect, optimize the material the formula, determine the phase and structure composition of reasonable insulation materials, and develop lighter heat insulation materials with better performance;
2.The key to the production of lightweight insulation is the introduction of internal pores. Increase the porosity of closed air, in order to increase the thermal insulation effect while increasing the high temperature load capacity;
3.With appropriate multi-phase composite materials to improve the original single-phase material high temperature thermal insulation properties, such as insulation materials with a certain fire resistance, etc., so that it has low thermal conductivity and high strength. The development of new technology for composite materials will provide a variety of possible ways to realize this idea.
In addition, with the rapid development of science and technology, continuous progress in human society, people’s growing awareness of self-protection, the selective use of energy-saving materials has become a general trend. The development of heat-insulating materials that are lightweight, have good thermal insulation properties, have a low environmental pollution, and have a long service life will become an effective way to save energy. It is believed that the development prospect of lightweight heat-insulating materials will become more and more broad.
