Distinguish between anti-static mats
Anti-static mats, also known as anti-static rubber, anti-static mats, etc., are generally two-layer structure, the surface layer is a static dissipative layer, and the bottom layer is a conductive layer. The color of the surface layer is green, gray, blue, etc., and there are smooth and matt surfaces, and the bottom layer is black.
There are many types of anti-static mats available in the market, such as PVC, all-rubber, and even many anti-static mats are produced from recycled materials. Operators will say that the quality of the anti-static mats they sell is the best, is it really good? Which one is better? Let's analyze it together.
Anti-static mats are mainly made of conductive materials, static dissipative materials and synthetic rubber. They are used for a long time, have good acid, alkali and chemical solvents, and are wear resistant. Easy to clean, so it can be seen that the main material of the anti-static mat is rubber, also known as nitrile rubber. Nitrile rubber is originally a natural semiconductor with antistatic function. Its molecular structure is composed of many carbon chains. It can store a certain amount of static electricity and can be introduced into the inner layer in a short time and dissipated. The biggest function of the anti-static table mat is to store a large amount of static electricity and discharge electricity in a moment, and the general life is about 5 years.
Compared with rubber anti-static mats, anti-static mats made of PVC are cheap. The reason why it can prevent static electricity is because anti-static agent is added in the production. This product belongs to chemical products, with 3-6 The moon will slowly fade away, which will also lead to worse and worse electrostatic effects.
After the above comparison, everyone should know that the material of the table mat is better. We can make a difference according to several methods, such as resilience, smell, fire, surface scratches, contrast softness, etc. These surface analysis can help you to distinguish the quality of it to a large extent. Some professional knowledge, it is not difficult for you to buy a good quality anti-static mat.
