乙炔瓶在使用过程中,随着乙炔气的释放,瓶内的丙酮要流失一些。按GB11638—89《溶解乙炔气瓶》规定,当新乙炔瓶在环境温度15—25℃的范围内,以不小于2m~3/h的流量连续放气,丙酮损失率应不大于50g/kg(丙酮/乙炔气)。为了保证乙炔瓶的安全性,所以在充装乙炔气 Acetylene bottle in use, with the release of acetylene gas, the bottle of acetone to be lost. According to the GB11638-89 “Dissolved Acetylene Cylinder” regulation, when the new acetylene bottle should be continuously deflated at a flow rate of not less than 2m ~ 3 / h at an ambient temperature of 15-25 ℃, the acetone loss rate should not exceed 50g / kg (Acetone / acetylene gas). In order to ensure the safety of acetylene bottles, so filling acetylene gas
