河北煤炭四处动力科,在1985年8月引进了电气设备防爆面磷化处理工艺,并在全处推广应用。九个多月的实践证明,这个处所有经过磷化处理的井下电气防爆设备,没有再出现失爆现象,既保证了井下电气设备的使用安全,又提高了设备的完好率,取得了良好的效果。 Hebei Coal Power Division, in August 1985 the introduction of the electrical equipment explosion-proof surface phosphating treatment technology, and promote the entire application. More than nine months of practice have proved that this place after all phosphating underground electrical explosion-proof equipment, there is no loss of explosion phenomenon, not only to ensure the safe use of underground electrical equipment, but also improve the equipment intact rate, and achieved good effect.
