(Summary description)The raw materials of explosion-proof tools are mainly beryllium bronze and aluminum bronze. The beryllium bronze alloy and aluminum bronze alloy do not produce sparks during impact or friction. They are very suitable for manufacturing safety tools used in explosive, flammable, strong magnetic and corrosive situations. BeA-20C alloy withstands 561IJ impact energy in air oxygen containing 30% hydrogen or 6.5-10% methane for 20 times without spark and combustion. The main functions of explosion-proof tools are: knocking, collision, falling hammer, impact, etc. will not spark, but explosion-proof media are not corrosion resistant in all cases. For example, in wet ammonia, some ammonium salts, acetylene, wet fluorine, chlorine, ammonium chromium, some dichromate, potassium hydride and other media, the degree of corrosion is quite large. And some media will react with copper alloy after contact, Explosion-proof materials with high risk are generated, such as acetylene steel produced by the combination of acetylene and steel. Under the above conditions, explosion-proof materials should be used in a dry environment as much as possible. After the completion of daily work, explosion-proof tools must have a proper maintenance stage, which plays a key role in the life of the tools, because if the maintenance of explosion-proof tools is not proper, our tools can not serve us for a long time. First of all, we should put the tools in a dry place to keep some parts of the work from being damaged.
