出于安全考虑,难燃液压液在一些特殊行业获得广泛应用,如煤炭、钢铁、冶金、电力等行业。介绍了国内外难燃液压液的检验标准,重点讨论了几类有代表性的液压液喷射燃烧难燃性。喷射燃烧难燃性检验结果与开口闪点、歧管难燃性检验方法得到的结果具有很好的一致性,是一种科学、有效的评价方法。 For safety reasons, flammable hydraulic fluid is widely used in some special industries, such as coal, steel, metallurgy, electric power and other industries. The test standards of the domestic and foreign flame retardant hydraulic fluids are introduced, and some representative flame retardancy of hydraulic fluid injection combustion are discussed. Flame-retardant combustion test results and the opening flash point, the test results obtained by the manifold flame retardancy has a good consistency, is a scientific and effective evaluation method.
