What anti-static knowledge? Electrostatic charging phenomenon is a common phenomenon, as in dry weather with a plastic comb hair, can be heard "crackling" sound of the discharge. The use of static electricity can list many examples of electric painting, electrostatic dust, electrostatic flocking, electrostatic photocopying, but these are the use of high voltage electrostatic field generated by the external energy to work, and the production process described below is generated harmful static electricity is not exactly the same, the following focuses on the static, static electricity hazards and measures to eliminate static electricity hazards. First, the static electricity generating substance is composed of molecules, molecules are made of atoms, atomic nuclei and its periphery by the electronic component. When the two substances in close contact and then separated, passed to an electronic substance and another substance is positively charged, another material was negatively charged electrons, thus creating static electricity. In the production of common electrostatic phenomena: friction charging, mobile charging, charged spray, impact charging, rupture charged droplets charged more. Second, the electrostatic electrostatic hazards of harms way are the following three types: 1. Fire and explosion fire or explosion hazard electrostatic largest. Static electricity, although modest, because the voltage is high and prone to discharge static electricity sparks. In the workplace with a flammable liquid, such as oil shipment places, it may be caused by static electricity spark fires; in explosive dust or explosive gases, vapors places, such as coal, flour, aluminum, hydrogen, etc., may be caused by static electricity sparks cause an explosion. 2. Shock shock caused by static electricity may occur in the body close to the electrostatic material time, that may occur in the human body electrostatic charge close to grounding when the moment static from your body up to thousands of volts. Static shock severity and body with static electricity stored energy related, energy, the more severe electrical shock. Electrostatic capacitance greater body or the higher the voltage, the more severe the degree of electric shock. Electrostatic energy generated in the production process is small, so the resulting shock does not directly make deadly. But the body may cause electric shock fall, fall, causing the second accident. In addition, staff can cause electrical shock stress affect. 3. Hinder production of electrostatic hinder production, or reduce product quality. In the textile industry, fiber-entangled static electricity, dust absorption, reduce the quality of textiles; in the printing industry, the paper line electrostatic missing, can not be separated, the impact of print speed and print quality; in the photographic film industry, the film static spark sensitive, lower film quality; in powder processing industry, static electricity powder adsorbed on the device, Powders filtering and delivery; static electricity may cause malfunction of electronic components; interference to radio communications. Third, anti-static measures necessary condition for explosion and fire caused by static electricity are: the presence of static electricity; electrostatic discharge level has been reached; hazardous locations; ignition energy of the flammable substance or a large explosion concentration limit has been reached. A necessary condition for the occurrence of electrostatic shock are: the presence of static electricity; has reached the discharged state. Interfere with the production of the necessary conditions caused by static electricity is conducted: an electrostatic capacity to some degree. Electrostatic hazards caused by the basic conditions are: the static, and presence; charged with the discharge of the object; the presence of flammable substances dangerous mixture. Therefore, it must take to reduce the above-mentioned basic conditions for the generation of static electricity, guidance and dissipate static electricity, to prevent electrostatic discharge, effective measures to control the concentration of hazardous substances and other combustible mixture in order to prevent static electricity hazards. Clear electrostatic hazards measures roughly ground method, the leak method, neutralization method, process control methods. 1. Ground method is to eliminate static electricity hazards easiest way. Ground is mainly used to eliminate static conductive body, it should not be used to eliminate static electricity insulator. If the insulator with static electricity, the insulator directly to ground but prone to spark. In a fire and explosion hazard place, in order to avoid a static spark caused by an accident, you should take the following grounding measures: (1) Where to processing, storage, transportation of various flammable liquids, gases and powders equipment, storage tanks, storage Cylinder and product transportation equipment, closed transport units, exhaust injection equipment, must be grounded mixers, filters, dryers, sublimation, a adsorber so. If the pouch-shaped filter made by a textile similar items, you can use a wire through the seam and be grounded. (2) factory and workshop of oxygen, acetylene and other channels must be connected into a continuous whole and be grounded. All other can produce static piping and equipment such as air compressors, ventilation and air ducts, especially local exhaust air duct must be connected into a continuous whole, and be grounded. Such as pipes made of non-conductive material, it should be in the tube or pipe around the metal wire and grounding wire. Metal non-conductive pipe joints must be grounded. (3) oiling funnel, float tank top, work stations and other auxiliary equipment or tools should be grounded. (4) Auto fuel tank should be with a metal chain, a chain of upper and tank car chassis connected to the other end in contact with the earth. (5) Some more dangerous places, in order to make reliable ground shaft, slip rings, brushes grounding method can be conductive lubricant or adoption. Static grounding device should be connected securely, and have sufficient mechanical strength, may be grounded by a grounding device with other purposes. 2. Take measures and adopt humidifier leak methods antistatic additives to promote themselves dissipate electrostatic charge from the insulator, this method is called leakage method. (1) humidification. Humidification is to increase the humidity of the air. Humidity for electrostatic leakage great. Humidity increases, the surface resistance of the insulator is greatly reduced, the electrical conductive reinforcing accelerate electrostatic leakage. If the relative humidity is maintained at about 70%, to prevent accumulation of static electricity. (2) adding antistatic additives. Antistatic additive is a special adjuvant, after some additives to produce static electricity insulation, can increase or ionic hygroscopic materials to enhance conductivity, accelerated static leakage; some additive itself has a good electrical conductivity. (3) the use of conductive material or paper insulation. For easy to produce static mechanical parts as a conductive material. Inner container made of insulating material, lined with a conductive layer or a metal network, and be grounded; using conductive rubber in place of the ordinary rubber or the like, will accelerate electrostatic charge leakage. 3. And law and law is an important measure to eliminate static electricity hazards. Static neutralization process is in place to try to electrostatic charge density of charged ions produced, the Department of electrostatic charge in and out. Static neutralization method can be used to eliminate static electricity insulator. You may use sensors and devices, and control hypertension, radiation and other devices in the elimination of static electricity hazards. 4. Speaking in front of the humidification process control method is a danger of measures to eliminate static electricity from the process. However, humidifiers not control static, but accelerating electrostatic charge leakage to avoid the accumulation of electrostatic charge to the degree of danger. In the process, it may adopt appropriate measures to limit the generation of static electricity, control the accumulation of electrostatic charge. For example: instead of using the gear belt drive to reduce friction; reduce the flow rate of liquids, gases or dust material, to limit the generation of static electricity; maintain normal tension belt to prevent slipping; perfusion fluid through the pipe to the bottom or close to the side wall of the container, Avoid shock and splashing liquid, etc. Other measures still do not belong to the above four measures, for example in order to prevent harm to human tape caused by static electricity, staff can wear antistatic overalls and work shoes, take ventilation, dust and other measures also help prevent static electricity damage.
