Safety shoes can prevent injuries. Generally speaking, shoes are easily corroded under the action of moisture and sweat, so the inner head must have anti-corrosion effect. When checking the corrosion resistance of the internal filter head, place the treated filter paper on both sides of the filter head, and take out the filter paper after a period of time. The spots on the head after 5 o’clock should not exceed, and the area of each spot should not exceed 5 mm.
Prevent puncture. It can prevent the soles of the feet from being pierced by sharp objects, and can withstand a puncture force of up to 1100n. The energy absorption of the shoe seat area is ≥20j; ambient temperature: 23℃±2℃; relative humidity: 50%±5%.
Oil resistant. According to the oil resistance standard test, the volume increase does not exceed 12%. According to GB/T3903.1, when the volume does not increase or decrease, the decrease is greater than 0.5% of the original volume or the hardness increase is greater than 10 (Shore A), then the crack propagation is not greater than 7 mm after 40,000 bending
Electrically insulated labor protection shoes are usually called insulated shoes. Suitable for electricians, electronic operators, cable installers, substation installers, etc. Note: Suitable for working environment where the power frequency voltage is lower than 1KV. The working environment should be able to keep the uppers dry. Avoid contact with sharp tools, high temperature and corrosive substances, and the upper bottom must not be damaged by corrosion.
