Anti-static mats should be regularly tested
Anti-static table mats should be regularly tested. Surface resistance testers with heavy hammers are recommended. High-precision instruments are recommended for conditions. The measured parameters will be more accurate. If you simply put anti-static mats on the work. On the countertop, the static indicators do not meet the requirements, and it is impossible to release the static electricity, which will cause a large amount of waste products. The quality of the products of the enterprise cannot be guaranteed, which seriously affects the development of the enterprise.
Let's share the measurement method of the table mat:
A. Place two measuring electrodes on the surface (using a surface resistance tester with a weight), the middle distance is 1M, connect the two wiring suppliers of the instrument to the electric level, and measure the resistance between the poles;
B. Place a measuring electrode on the ground, connect the meter to the electrode a few days before grounding, and connect the grounding terminal to the grounding grid of the workshop, and measure the resistance value of the ground point to the ground;
C. Select at least 5 test points for each working environment and warehouse. The test points should be selected at the place where the production workers operate or move frequently, and require 1M away from the grounding body.
D, whether it is the inter-electrode resistance value or the polar resistance value, take the arithmetic mean;
E. The resistance value under the conductive rubber pad is 5×104Ω or 5×104-106Ω; the surface resistance of the anti-static pad should be in the range of 106-109Ω.
High-quality environmental protection anti-static mats, if necessary, you can contact customer service to send samples for free
1. The anti-static table mat adopts double-layer structure. The surface layer is anti-static layer. The bottom layer is black conductive layer.
2. It is mainly composed of static dissipative layer and conductive layer. It is made of high-quality nitrile rubber as the main raw material, adding high-quality conductive carbon black and static dissipative agent.
3. This product has good wear resistance, oil resistance, acid and alkali resistance, anti-aging, anti-combustion, high elasticity, smooth surface and no curling.
4. The appearance is green, alleviating visual fatigue, the surface layer is 1mm thick, the service life is twice as long as the average product, and the surface is smooth and easy to stick dust.
5. The volume resistance is ≤107Ωcm, the static discharge time is short, and the service life is not less than 2 years.
6. Product general specifications: 1.2m (width) × 10m (length) × 2mm (thickness)
7. Exported abroad to be selected as one of the products, the symbol ROHS 2.0 detection
8. If you need samples, you can contact customer service for free samples.
