Different styles of anti-static shoes
Electrostatic work shoes are divided into ordinary static area and clean area shoes. There are two kinds of materials used in the sole, pvc and pu. The upper has pvc leather and pu leather. The midsole is a conductive electrostatic polyester cloth and t / c cloth. The shoes for general static area have various styles of uppers, and users can design uppers according to the requirements of enterprises.
In the context of today ’s environmental protection, pu soles / pu leather surface antistatic shoes are gradually being valued. Although they are not recyclable, they are light in wear and moderately breathable. , Deeply loved by well-known large enterprises. Although the price of anti-static shoes is different, from the beginning, the hardness / resistance of soles of anti-static shoes should be checked according to national standards, and the thickness / tension of leather should be analyzed. In the combination of the upper and the sole, attention should be paid to its adhesion. If there is glue opening, it will affect the environment of the electrostatic work area. The dust-free boots will have an increase in the amount of dust generated, so that the corresponding purification level cannot be achieved.
In general, under the same material conditions, the adhesion is more ideal, for example: pu leather surface corresponds to pu soles, pvc leather surface corresponds to pvc soles, affected by cost control, anti-static shoe factories often use pvc leather surface In combination with the pu bottom, under this condition, when the help surface and the pu bottom are treated, a special treatment agent is usually used to make it strongly bonded during the production process. This method can be used in a non-washing state. However, the dust-free boots are often washed repeatedly, and the glue may appear after drying, which depends on the selection of PVC leather. In the process of testing electrostatic shoes, electrostatic performance is also a key link. At the appropriate humidity (22 ℃ -25 ℃) and humidity (not less than 45 ℃) inspections, two data, surface resistance and grounding resistance, must be measured.
