How to effectively distinguish which material is used in the sole of anti-static shoes
More and more high-tech electronic products bring great convenience to our daily life production. Electronic products are also very sensitive and fragile. Therefore, electronic products have strict requirements on the production environment. The existence of static electricity has caused great problems to electronic products. Threats, in order to protect the safe production of electronic products, workers need to wear anti-static shoes, anti-static shoes need to be equipped with anti-static clothing in the clean room. The anti-static shoes can guide static electricity from the human body to the earth, thereby eliminating static electricity of the human body, and at the same time effectively suppressing the dust generated by the walking of the person in the clean room. In order to cater to various production needs, anti-static shoe manufacturers have chosen different anti-static materials to make anti-static shoes. The materials of anti-static shoes can be roughly divided into three materials: SPU, PU and PVC, but many people do not know. How to distinguish between these three materials.
First of all, SPU material of anti-static shoes, SPU material is generally used to make anti-static slippers, because SPU material can be molded at one time, relatively light, very suitable for custom anti-static slippers. The distinction between PU and PVC can be achieved by looking at the two methods. First, the base fabric of the PU is much thicker than the PVC from the corners. In the touch, PU material anti-static shoes feel softer, while PVC anti-static shoes are relatively hard to feel. The third can smell, burn the PVC and PU materials with fire, the burning PU material tastes lighter, and the PVC material tastes much stronger.
If you don't know how to distinguish the material when you choose anti-static shoes, you can use the above three methods to make a distinction. In fact, the SPU, PU, and PVC materials of the anti-static shoes can also be seen with the naked eye. This requires everyone. Do more to understand, so you can make better choices when buying anti-static shoes.
