阻化剂是一项新的防火技术,英、西德、苏联、匈等国正在试验研究和应用,但真正应用到工作面的也只有苏联和西德等少数国家。关于阻化剂防火原理问题,一般都认为阻化剂氯化钙、氯化镁是一种吸水性很强的盐类,在喷洒的过程中它能浸入到煤的层理、节理和微小的裂缝中去;在煤的表面形成氯化物的液膜,能阻止氧和煤的接触,减少煤的氧化,从而起到了防火作用。1974～1975年辽宁省煤炭研究所曾同平 Resistance is a new fire-retardant technology, Britain, West Germany, the Soviet Union, Hungary and other countries are experimental research and application, but the real application to the face of only the Soviet Union and West Germany and a few countries. On the principle of fire retardant inhibitor, generally considered the resistance of calcium chloride, magnesium chloride is a highly water-absorbing salts, it can be immersed in the spray process of coal bedding, joints and tiny cracks To; the formation of chloride in the surface of the liquid film, can prevent oxygen and coal contact, reduce the oxidation of coal, which played a role in fire prevention. 1974-1975 Coal Institute of Liaoning Province had the same level
