一、概况近几十年来,能源越来越紧张,特别是73年以来,资本主义国家出现能源危机,使能源成本提高了好几倍,迫使许多国家展开节约能耗的研究工作,陶瓷纤维的试验,应用和研究工作也就是在这种情况下开始的。在高温的工业窑炉中,能耗很大,大量的热能消耗在炉窑本身和散失到周围环境中去了。针对这种情况,工程技术上就必须探索一种能耐高温的保温绝热材料;也就是同时具有耐火度高,导热系数低和热容小的新型材料。根据固体耐火材料的导热,保温机理,采用各种不同手段(如发泡、膨胀、纤维化等)发展了许多新型轻质耐火保温材料。
I. Overview In recent decades, energy is getting more and more tense. Especially since 73 years, the energy crisis has taken place in capitalist countries, resulting in an increase in energy costs several times, forcing many countries to carry out research on energy conservation and testing of ceramic fibers That’s where application and research work begins. In high-temperature industrial kilns, energy consumption is high and a great deal of heat is lost in the kiln itself and lost to the environment. In response to this situation, engineering must explore a high temperature insulation insulation material; that is, both high refractoriness, low thermal conductivity and heat capacity of the new material. According to the solid refractory thermal conductivity, thermal insulation mechanism, using a variety of different means (such as foam, expansion, fibrosis, etc.) the development of many new lightweight refractory insulation materials.
