液化石油气制备金属焊割气的优化研究

Optimized research of liquefied petroleum gas manufacture metal welding gas

制备了一种液化烃类焊割气,由5 kg液化石油气加入15 mL 30%过氧化物和10 mL高锰酸钾溶液(2.5 gKMnO4加水500 mL)组成。该焊割气的焊割速度达860 mm/min,优于乙炔气,可代替乙炔气广泛应用于实际生产中,具有较强的应用价值。

A liquefied petroleum gas was prepared,which consiste of 5 kg LPG,adding 15 mL 30% peroxide and 10 mL potassium permanganate solution（2.5 g KMnO4,water 500 mL）.Its cutting speed can reach 860 mm/min,which is better than the acetylene gas,it has good application value in actual production.
