Because of the work needs of some industries, it is necessary to wear anti-static shoes, but anti-static shoes are not casually worn. Everyone must understand the correct wearing requirements of anti-static shoes:
First, in order to ensure the rapid elimination of static electricity accumulated by the human body, the resistance of the ground at the time of normal work should be no more than 1.0 × 10 ^ 8 Ω;
Second, anti-static shoes also have certain requirements when wearing, the bottom of the shoes can not be insulated with insulating impurities, and at the same time waterproof and moisture-proof;
Third, pay attention to avoid wearing insulated thick socks and insulating insoles at the same time. The resistance of the anti-static shoe sole must be in the range of 0.5×10^5 Ω to 1.0×10^8 Ω. The resistance value of the sole should be measured after wearing for 200 hours to ensure that the resistance value of the shoe is within the specified range.
When you measure its resistance value, you should pay attention to the following points:
1. First place the vulcanized new shoes for more than 24 hours, then place them in the temperature and humidity environment required for measurement for more than 2 hours, in order to measure the most standard answers;
2. Connect the circuit, the measuring voltage applied to the shoe is 500±25V, the electric power should not exceed 3W, and the contact between the shoe body and the measuring electrode is good;
3. Adjust the output voltage of the voltage source to the value specified by the anti-static shoes;
4. When the report is issued, the test conditions of the shoes, such as temperature and humidity, should be recorded truthfully. The model and measurement results of the shoes must be filled in truthfully.
Anti-static shoes can eliminate the accumulation of static electricity in the human body. Anti-static shoes are suitable for use in flammable workplaces, such as gas station operators and liquefied gas filling workers. It is forbidden to use as insulated shoes; wear anti-static shoes should not wear insulated wool thick socks or use insulated insoles at the same time; anti-static shoes should be used together with anti-static clothing; anti-static shoes should not be used for shoe resistance. Once tested, if the resistance is not within the specified range, it cannot be used as an antistatic shoe.
