In recent years, fireproof plugging materials have attracted widespread attention all over the world. As a typical organic elastic fireproof plugging material, fireproof mud has the advantages of long-term non-curing, good plasticity and high temperature resistance. However, with the development of society and technological progress, converter stations, as an important hub of the current HVDC transmission system, have put forward higher requirements for fireproof materials, especially in the face of power fires and hydrocarbon fires.
Power fires and hydrocarbon fires are two major fire threats at converter stations. Polymer materials and transformer oils in power equipment are potentially flammable materials that can have serious consequences in the event of a fire. Therefore, how to effectively deal with these special fire forms has become an important topic in the current research field of fireproof materials.
In this context, inorganic expanded fireproof mud came into being. Compared with the traditional organic elastic fireproof plugging material, inorganic expanded fireproof mud has more stable chemical properties and higher fire resistance temperature, which can better cope with the challenges of power fire and hydrocarbon fire. Its main features include high temperature resistance, non-toxic and harmless, no expansion, no cracking, etc., making it have a wide range of application prospects in the field of fire protection.
Studies have shown that inorganic intumescent fireproof mud performs well in power fires and hydrocarbon fires. In power fires, its stable chemical properties and high temperature resistance can effectively isolate the fire source, reduce the possibility of fire spread, and reduce losses. In hydrocarbon fires, the non-expansion and non-cracking characteristics of inorganic expanded fireproof mud can effectively control the fire and reduce the damage caused by the fire.
However, at present, the research on the role of inorganic expanded fireproof mud in power fires and hydrocarbon fires is still limited. In order to solve this problem, future research can be carried out from the following aspects: firstly, strengthen the performance evaluation of inorganic expanded fireproof mud in power fires and hydrocarbon fires, especially under different temperature and air pressure conditions; Secondly, the formula and preparation process of inorganic expanded fireproof mud were optimized to improve its ability to cope with special fire environments. Finally, the collaborative application of inorganic expanded fireproof mud and other fireproof materials was carried out to explore the comprehensive protection effect of a variety of fireproof materials on special fires.
In short, as a new type of fireproof material, inorganic expanded fireproof mud has shown great potential in the protection application of power fires and hydrocarbon fires. In the future, through in-depth research and practical verification, it is believed that inorganic expanded fireproof mud will provide more reliable protection for the safe operation of converter stations.
