乙炔是一种可燃性气体,它与氧气混合燃烧时产生的火焰温度可达3000～3300℃.广泛应用于金属切割.乙炔有一个特点:如果将其装在一般容器里压力不能超过0.2Mpa,否则就要发生爆炸.如果将乙炔装入钢瓶中填满浸透雨酮的多孔材料内,就可在1.5～2.5Mpa之间安全制取,贮存瓶内供使用.乙炔钢瓶在使用过程中严禁横躺卧放,否则溶解有乙炔的丙酮就会从钢瓶中流出,不仅乙炔与空气混合而发生爆炸,同时雨酮蒸气与空气混合到1.6 ～13.0%时遇明火也会爆炸.因此,乙炔钢瓶只能直立使用.其次,乙炔钢瓶在使用过程中,必须安装回火防止器,因为一旦发生回火,如果没有安装回火防止器,就可能使火焰进入乙炔钢瓶内,造成钢瓶内温度急剧上升,同时使钢瓶内的压力急剧升高,造成钢瓶爆炸事故.
Acetylene is a flammable gas, which when mixed with oxygen combustion flame temperature up to 3000 ~ 3300 ° C. Widely used in metal cutting. Acetylene has a feature: if the pressure in the general container can not exceed 0.2Mpa, Otherwise it will explode.If the acetylene into the cylinder filled with porous materials impregnated with rain ketone, can be safely prepared between 1.5 ~ 2.5Mpa, storage bottle for use. Acetylene cylinders are prohibited during the use of horizontal Lying on the lying, or dissolved acetylene acetone will be out from the cylinder, not only acetylene and air mixture explosion, while the rain and ketone vapor mixed with air to 1.6 ~ 13.0% of the case of fire will explode.So acetylene cylinders Second, the acetylene cylinder must be installed in the use of tempering preventer, because once the tempering, if not installed tempering preventer, it may make the flame into the acetylene cylinder, resulting in a sharp temperature rise in the cylinder, At the same time so that the pressure inside the cylinder rose sharply, resulting in cylinder explosion.
