What are the features of anti-static shoes?
The anti-static shoes are made of loose electrostatic material PU or PVC material, and the sole is integrally formed on the upper surface, and then the upper thread is reinforced. The finished shoes are beautiful, generous and strong. In particular, PU anti-static shoes have superior wear resistance and are more than 5 times more wear-resistant than ordinary rubber shoes;
First, anti-static shoes commonly used materials: wearing anti-static shoes is an effective and reliable way to discharge the electrostatic charge of the operator, due to the requirements of enterprise products, the current anti-static shoes not only need anti-static function, but also need Use low dusting materials to suppress the dust generated by people moving around in the clean room;
Upper material: anti-static PVC leather, PU leather, canvas, etc.;
Second, the characteristics of PU materials and PVC materials:
High strength, thin and elastic, soft and smooth, waterproof; good tensile strength and tortuosity at low temperature, good light aging resistance and hydrolysis stability; strong flexibility, appearance and performance Close to natural leather, easy to wash and decontaminate, easy to sew; smooth and compact surface, can be used for a variety of surface treatment and dyeing, variety;
Third, PU material and PVC material maintenance methods:
Wash with water and detergent, avoid petrol cleaning; can not dry clean, only wash, recommended washing temperature 40 ° C, drying temperature 50 ° C; can not be exposed to sunlight; can not touch some organic solvents, should not be bleached.
Fourth, the comparison of PU shoes and PVC shoes:
PVC and PU materials are common materials for making anti-static shoes. The full name of PVC is "polyvinyl chloride", which is a type of plastic. The full name of PU is "polyurethane", which is a type of synthetic leather. There are many differences between the two, and the products made with these two materials are also very different in performance.
Commonly used anti-static shoes must be equipped with thin nylon stockings or socks mixed with conductive fibers, rather than socks that can be worn with wool and synthetic materials. There is no additional insole in the anti-static shoes, especially the insulating insole. Do not stick the insulating film or other paint on the sole. The venting resistance of the local ping is very large, (10 to the 10th power) wearing anti-static shoes can not effectively eliminate static electricity.
For the newly purchased anti-static shoes, all the resistances should be checked before use and recorded. After using for a period of time, when the surface of the shoes is significantly contaminated, or the sole is worn, the shoe body is deformed, or the original person has When the electrostatic click is felt, the resistance of the antistatic shoe must be retested and checked. The resistance of anti-static shoes changes due to humidity, so it should be tested in summer and winter to grasp the extent of change.
