- The material of explosion-proof tools is copper alloy. Due to its good thermal conductivity and almost no carbon, the heat generated in a short period of time is absorbed and conducted when the tools and objects rub or collide. Another reason is that the copper itself is relatively soft, so it has a good concession when rubbing and impacting, and it is not easy to produce small metal particles, so we can hardly see sparks. Therefore, explosion-proof Tools are also called non sparking tools tools.
- Petroleum refining and petrochemical industry, coal mine, oil field, natural gas chemical industry, gunpowder industry, chemical fiber industry, paint industry, fertilizer industry and various pharmaceutical industries. Vehicles and aircraft of petroleum wheel and liquefied petroleum gas, warehouses dealing in inflammable and explosive goods, electrolysis workshop, communication machine assembly workshop, places where tools are required to be rust free, wear-resistant and antimagnetic, etc.
- After the use of explosion-proof tools in our daily work, there should be a proper maintenance stage, which is very important for the life of tools, because if the maintenance of explosion-proof tools is not appropriate, our tools can not serve us for a long time. First of all, we should keep the tools in a dry place, so that some parts of the work can not be damaged. In our daily work, after 20 times of continuous knocking, the surface attachment of the tool should be treated and cleaned before use. Never use the tool continuously, so as to avoid heating the tool due to long-term friction, which may damage our tool products.
