    Problems needing attention in application field of explosion-proof tools

    Jun 15, 2019
    DESCRIPTION

    Problems needing attention in the application of explosion-proof tools:

    In the following two cases, the sparks that ignite are generated not by the explosion-proof tool itself, but by the work object. The use of explosion-proof tools cannot prevent such explosion, but other explosion-proof methods should be adopted.

    1. When the tool hits the rock, it may produce sparks. In this case, the generation of sparks has nothing to do with metal. This electrical energy is released in the form of electrical sparks. Sparks are especially likely to occur in rocks containing quartz, silica, and sandstone. Generally speaking, the higher the content of quartz in rocks, or the larger the particles, the easier it is to ignite. In order to prevent the occurrence of explosion accidents, rocks can be injected into the water for explosion.

    2: when striking or rubbing aluminum coated copper and iron thermal work with explosion-proof tools, it is possible to ignite explosive material sparks. If the powder grains of aluminum, magnesium and their alloys adhere slightly to the surface of rusty steel. After being hit by a hard material or even hard rubber or plastic, a violent exothermic "aluminum-thermal reaction" may occur, which is likely to detonate.
