A
metal lead
powder production method comprises the steps of melting
metal, atomizing and the like, wherein the temperature of fusing lead liquid in a
metal melting process is controlled at around 425-440 DEG C, a
benzotriazole additive is added in the process of atomization, the
benzotriazole additive accounts for 0.001%-0.005% of the melted metal lead liquid in weight, and
high pressure air flow which is added in the process of the atomization is controlled at about 5-6.5 m <3> / minute (min). According to the metal lead
powder production method, an additive is selected in the process of metal lead power production in an atomization method, the properties of the addictive, the interaction between the additive and the metal and the favorable environment of atomization are used, and therefore the additive is atomized to form a protective layer which can avoid oxidation and
caking on the surface of the metal lead
powder.
Metal lead powder products which are produced through the metal lead powder production method are packed with normal packaging, and the oxidative
deterioration rate of the metal lead powder products can be controlled within the range of 0.5%-3.5%. Due to the fact that the normal packaging is used, the production cost is reduced effectively, the safety of a production
system is good, returned goods rate is reduced greatly, and economic benefit is remarkable.
