How to purchase dust-free ESD shoes
ESD shoes are currently used in microelectronics, medicine, aerospace, precision machinery, microelectronics factories, etc. With the widespread use, some buyers have begun to worry and don't know how to choose. The editor below will take you to have an in-depth understanding.
ESD shoes are also called purification shoes and anti-static dust-free shoes. The uppers are made of special polyester filaments and high-performance permanent conductive fibers. The conductive fibers are stripes or grids with a spacing of 5mm, which have good electrostatic discharge effects. At the same time, it also effectively suppresses dust generated by workers moving around in the clean room.
As special work shoes, anti-static dust-free shoes are different from ordinary work shoes in terms of selection and purchase, and require certain identification skills and experience. People who often use anti-static shoes have experience and have very high requirements for the material ratio of the soles, such as the color, weight, hardness, odor, performance, etc. of the soles, which must be quite suitable.
Used in a clean room with dust-free clothing, dust-free shoes are a very reliable human body static electricity and dust control system. Since dust-free shoes and soles are made of static dissipative materials, they have good electrostatic properties. The sole and upper are integrally formed, so employees will not feel soreness or fatigue in their legs due to standing or walking for a long time, meeting the actual requirements of standing or walking around for a long time in a clean room. The anti-static function of anti-static dust-free shoes mainly lies in the application of sole and insole technologies. Currently, there are three sole molding technologies, including PU, PVC, and SPU one-time molding. It is easier to distinguish between PU and PVC. From the corners, the bottom of PU is much thicker than PVC, and there is also a difference in feel. PU feels much softer than PVC, while SPU is somewhere between PU and PVC.
Therefore, when choosing dust-free shoes, you must pay attention to the material of the soles to see which one is the most suitable. In addition, when buying dust-free shoes, special attention should be paid to the material of the insoles, which should also be anti-static, so that it can truly discharge static electricity.
In addition, dust-free shoes need to be purified and cleaned frequently. If the soles cannot be dried in time after purification and cleaning, bacteria will breed and seriously affect wear. After purification and cleaning (choose a professional purification and cleaning company), there will be no phenomenon that the soles cannot be dried (no bacteria will breed), and it will not affect the cleanliness of the dust-free purification workshop.
