Background

At present, powder in the industrial production process is a general name of dust, powder and granular substances. In various industrial production environments, a large amount of powder is generated in the production process, and comprises metal powder (aluminum powder, zinc powder, ferrosilicon powder, magnesium powder, iron powder and aluminum processing grinding powder), coal, grains (wheat, starch, sugar and milk powder), feed (blood powder and fish powder), agricultural and sideline products (cotton, tobacco and tea powder), forest products (paper powder and wood powder), synthetic materials (plastics and dyes) and the like. The powder of the materials is accumulated continuously due to charged dust, and when reaching a certain amount, the powder can discharge to generate electric sparks, thereby forming a direct fire source for explosion. The reason why the explosive combustion is easy to occur is that elements such as strong reducing agent H, C, N, S exist, and when the elements coexist with peroxide and explosive powder, the elements are decomposed, a large amount of gas is generated by oxidation reaction, or although the amount of the gas is small, a large amount of combustion heat is released to form explosion, so that great safety accidents are caused.

Statistics show that powder industrial disaster accidents are closely related to powder static electricity, and the proportion of dust explosion accidents caused by static electricity and electric sparks is relatively large in the powder industrial production process, wherein the damage of the static electricity is already to the extent that people have to pay high attention to the damage.
