The harm of static electricity in production: For example, in the plastic shell production line, due to static electricity, the plastic shell will be sprayed, electroplated, rough on the surface, have many trachoma, and have a poor feel. · In assembly lines such as drum paper, leather, plastic, chemical cloth/film, etc., due to the high insulation of the material, fast running speed, surface charge is not easy to dissipate, and the static electricity is extremely high, when the operator touches it, there will be an electric shock, and it can cause breakdown between the material layers, affecting product quality. · In the electronics industry, IC, LCD, LED, and other fine assembly lines, according to statistics, static electricity causes more than 20 billion US dollars in losses every year to the electronic device manufacturing industry! · In printing and packaging companies, static electricity can cause equipment control failures. ； Paper feeding is unstable and paper delivery is uneven. ； In transmission printing, it will also cause low overprint accuracy and serious ink whiskers, seriously affecting product quality. ◎The harm of static electricity to the human body We know that static electricity is very harmful in industrial production. It not only affects production, but also easily causes various fire and explosion accidents. Research has found that static electricity is also harmful to the human body. The human body is exposed to static electricity radiation for a long time, which can make people restless, have headaches, chest tightness, difficulty breathing, and cough. In family life, static electricity is not only found in chemical fiber clothes, but also in carpets under your feet, daily plastic utensils, shiny painted furniture, and various home appliances. Static electricity can absorb a large amount of dust in the air. The more charged it is, the more likely it is to absorb. The greater the amount of dust attached, and dust often contains a variety of toxic substances and germs, which can irritate the skin and affect the luster and tenderness of the skin, or cause skin sores in severe cases. In more serious cases, it can cause bronchial asthma, arrhythmia and other diseases. How to choose anti-static flooring? When choosing an anti-static movable floor in the construction of a computer room, you should pay attention to the following points: 1. First, you need to accurately determine the total area (or number of pieces) of the anti-static floor and various accessories required for the construction of the computer room (standard ratio 1:3.5, 1: 5.5) quantity, and leave a margin to avoid waste or shortage. 2. Fully understand the varieties and quality of anti-static flooring produced by manufacturers, as well as various technical performance indicators. The technical performance of anti-static flooring mainly refers to its mechanical and electrical properties. The mechanical properties mainly consider its load-bearing capacity and wear resistance. Install the entire anti-static floor on the overlapping trusses. After leveling the anti-static floor, its load-bearing capacity should reach a uniform load greater than 1000kg/m2. The concentrated load on any part of the anti-static floor should be greater than 300kg. When a 6cm diameter loading point bears a 300kg load, the deflection should be less than 2mm and there should be no permanent deformation. The adjustable support should be able to withstand a vertical load of more than 1000kg, and the board surface should have certain friction resistance. The electrical properties are mainly system resistance and surface resistance. The system resistance should be 106Ω-109Ω. When the temperature is 21±1.5℃ and the relative humidity is 30%, the electrostatic voltage of the anti-static floor should be lower than 2500V, and the surface resistance value should be 106Ω-109Ω. 3. The load of the anti-static floor should be determined based on the weight of the heaviest equipment among all the equipment in the computer room. This can prevent some equipment from being overweight and causing permanent deformation or damage to the floor. 4. The anti-static floor is less affected by external environmental conditions. That is, it will not significantly expand or contract due to excessively high or low external ambient temperatures. That is, when the temperature of the computer room is slightly higher, the anti-static floor will expand and expand and cannot be removed and replaced. ； When the temperature is low, the anti-static floor shrinks, causing a loose feeling. The amount of shrinkage of anti-static flooring affected by the environment should be less than 0.5mm, and the amount of deflection of the board surface should be less than 0.25mm. 5. The surface of the anti-static floor should be non-reflective, non-slip, corrosion-resistant, dust-proof, non-vacuuming, and easy to clean.
