 Explosion-proof hand pump 
 Brand: the anti- 
 Type: Power Conference 
 Product Performance Description: Ex tool material is copper alloy, due to the good thermal conductivity of copper and almost no carbon characteristics, so that tools and objects, friction or impact, a short time the heat is absorbed and the conduction, another reason As the copper itself is relatively soft, friction and collisions have a good compromise and difficult to produce small metal particles, so we barely see the spark, so no spark proof tools, also known as tools. 
 Impact or explosion-proof tools spark does not occur when friction is very suitable for manufacturing the explosive, flammable, corrosive occasions to use magnetic and security tools.
