Electrostatic hazard and static elimination in flocking plants
Electrostatic phenomena in modern industrial production are ubiquitous. Because industrial production inevitably avoids mutual contact and mutual movement between processing materials and processing machinery, physical conditions of various forces, heat, sound, light, and electricity may become factors that generate static electricity. Static electricity is also divided into two, beneficial and harmful to people's production and life. Electrostatic flocking, electrospinning, electrostatic precipitator, electrostatic spraying, xerography and electrets provide many new processes, new technologies and new equipment for industrial production, bringing a good economy to production and construction. Benefits and social effects. However, static electricity often causes great harm to production. The flocking factory uses flocking while using static electricity, and it also affects production due to static electricity.
Here I will know a little about the hazards and countermeasures of static electricity in flocking factories.
About the danger of static electricity
The so-called electrostatic hazard refers to the damage caused to people's production and life due to the phenomenon of static electricity. It is mainly divided into two categories: one is the sudden explosion caused by static spark discharge, and once it happens, it often causes a one-time huge loss. . Another type of electrostatic hazard is the adsorption caused by the electrostatic force, which brings trouble to the production. The damage has a wide range of influences, and the damage is not easy to count, and sometimes it is not easy to detect, so it is not easy to attract attention. In fact, this kind of Electrostatic hazards have a major impact on product quality and labor productivity. He also occurs in all aspects of flocking production. Most of the materials produced by flocking are chemical fiber materials, which are easy to generate static electricity, and the climate is relatively dry. The static charge generated during flocking production is not easy to run off, and it accumulates on the cloth surface. The more you absorb the hair, the more you absorb it. Even if the hair is floating in the bristle box, it is difficult to be brushed off, and sometimes the more the brush is absorbed, the more it absorbs. This is because the brush constantly rubs the flocking cloth during the brushing process, and generates a large amount of static electricity. Even if the floating hair is forcibly brushed down, it will be pulled back to the cloth surface by electrostatic force. So eliminating static electricity should be a big problem.
About static elimination
The so-called static elimination, here includes two meanings, one is that static electricity has been produced and tried to eliminate, and the other is that static electricity is not produced before trying to prevent it from being produced. Therefore, there are always two aspects to static electricity: on the one hand, prevention and reduction of static electricity generation. On the other hand, it prevents and reduces the accumulation of static electricity. At present, the measures to solve static electricity in the industry come down to the following: one depends on "ground" (take grounding measures); the second depends on "devices" (installation of various static eliminators); the third depends on "agents" (add various anti-statics) Agent). Grounding in the petroleum and chemical industries is a major measure, and grounding is rarely able to solve problems in the textile, flocking, and papermaking industries. The main thing is to install a static eliminator and add an antistatic agent. Eliminating static electricity with the "grounding" method is one of the simplest measures to eliminate static buildup. He bleed the charge on the charged body to the earth through the metal (or wire) connected to the ground. If the charged body itself is a conductor, the effect can be achieved. However, it is futile to attempt to eliminate static electricity by using grounding measures for materials that are electrically insulated (such as flocking cloth). Because it is difficult to move the charge on the insulating material, it is not possible to leak the charged charge by grounding like a conductor. In addition to the "grounding" measures, the main method for eliminating the main application of industrial electrostatics is to install various static eliminators to promote the ionization of the air around the charged body, and to achieve static elimination by electrostatic neutralization. At present, the static eliminator can be roughly divided into
There are three types: one is external photon ionization, the other is radioactive ionization, and the third is tip discharge type.
