随着石化工业的发展,生产或使用石油产品等可燃物质的单位和场所愈来愈广泛。可燃物质是形成燃烧的基础材料,分为固态,液态和气态,就其危险性而言,气态最大,液态次之,固态最小,都是极危险的易燃易爆物质。就可燃气体而言,与空气混合成爆炸性气体后接触火源就会产生爆炸。爆炸按其性质分为化学性爆炸、物理性爆炸和综合性爆炸三种类型。可燃性 With the development of the petrochemical industry, the units and places where flammable substances such as petroleum products are produced or used have become increasingly widespread. Combustible material is the basic material of combustion, which is divided into solid, liquid and gas. In terms of its danger, the gas is the largest, the liquid is second, the solid is the smallest, and both are extremely dangerous inflammable and explosive materials. In the case of combustible gases, explosives are formed when exposed to an ignition source after being mixed with air as an explosive gas. According to their nature, the explosion is divided into three types: chemical explosion, physical explosion and comprehensive explosion. Flammability
