There are strict regulations on smoking and open fire in flammable and explosive places such as chemical plants and oil refineries. How do combustion and explosion occur? In fact, at present, many explosion accidents are caused by mechanical sparks generated by metal impact, but many people are unaware of it. How to avoid these mechanical sparks?

Chenghua manufacturing suggests that some equipment in these inflammable and explosive factories that often have metal collision adopt explosion-proof materials, such as explosion-proof chain hoist for hoisting equipment, explosion-proof lamp for lighting, etc. The explosion-proof chain block adopts aluminum bronze as blank, and the collision will not produce mechanical sparks, so as to effectively avoid the occurrence of open fire.
