Electrostatic control laboratory instrument not only for safety, incidental purpose may also improve the quality of products, the grinding operation, for example, electrostatic charge can affect the finished product is excellent quality, or electrostatic charge can cause the fibers in the running of some textile mills, vertical rather than supine, resulting in defective. As we all know, chute or pipeline transport materials savings electrostatic charge, resulting in material adhered to the inner wall of the chute or pipe, this will cause clogging.

    1, the minimum ignition energy

    Electrostatic discharge caused by fire or explosion hazards, the discharge occurs in the combustible gas mixture can be converted into heat, the combustible gas temperature rise exceeding the ignition temperature results. The temperature rises to the ignition temperature of minimum energy called the minimum ignition energy as an explosion, fire, the value of a target value.

    2, to prevent electrostatic disaster countermeasures

    The electrostatic disaster With the charge generation, charge accumulation, discharge phenomenon, flammable substances exist four conditions occur. Eliminate these conditions can prevent the occurrence of disasters. Is important should accurately determine the Suppression of which of the four segments, and take appropriate measures. Starting to introduce their specific methods intended to prevent, suppress with a static point of view as the basic measures to prevent electrostatic disasters.

    (1) inhibition of the generation of static electricity: Because of the occurrence of static electricity source is friction between the objects or separating action, so to be suppressed as much as possible of these effects. For example, in the liquid conduit conveying dust air conveying or extrusion of plastic and other operations, the best approach is to reduce the speed. In fact, this will affect the operating efficiency. Petroleum safety velocity of 1m / s or less. Static electricity due to the different substances with different charge or polarity. Therefore feasible measure is to avoid the use of easily charged insulating material, the use of a static-generating materials by combining Difficult.

    (2) to promote the occurrence of leakage of charge: Disaster Response, the easiest way is to be grounded. The method is to quickly disappear into the earth of the occurrence of charge through metal conductors. However, using this method, if the charged body is a conductor can be simply eliminated, and the insulating material of the plastic or synthetic, petroleum like, since the charged portion of the charge is difficult to move, with little effect.

    Further, there is attached to the object within the method of the conductive substance of the charge drain. This includes added metal powder or carbon black, the chemical class or plastic using a hydrophilic finish to prevent charging in the flooring material of the tire or the operator's boots and chemical plants. If the increase in the relative humidity in the air, it is a water-absorbing layer is formed in a surface to enhance the conductivity, and a humidity of 80% or more is hardly charged. To do this in place charged may can improve regulation humidity device or sprinkler and other methods to increase the humidity. But the problem is that people may feel unwell or have an adverse effect on the equipment and products.

    (3) eliminating the charged charge: in the case of even inhibit charge occurs, prompting the charge leakage, still with electrostatic actively eliminated with the electrostatic. This can be used in addition to static in addition to static in the development and sales. The current development in addition to static device is the use of ion charge removal. Ions generated by the self-discharge type in addition to electrical voltage Additional addition to electrical, radioisotopes addition to electrical three kinds.

    3, electrostatic protective earthing

    Where processing flux, powdered substance or other flammable products, often there is a dangerous potential, because the accumulation of static electricity on the device, the processing of the material, even in the operator body. Electrostatic charge discharge Crackdown flammable or explosive substances or other equipment, would inevitably lead to a fire and explosion, causing many casualties and bring a lot of property damage each year.
