How to judge the pros and cons of anti-static table mats
1. Whether it meets the anti-static index specified by the standard (resistance is 1*10^6 ohm~~1*10^9 ohm, friction voltage <200V, static decay time <2s), the resistance of the newly purchased table mat is 5 *About 10^8 ohms, it is difficult to guarantee the validity period of 1.5 to 2 years.
2. The surface should have no heavy odor, should not be shiny and free of fine sand. If it is shiny or there are fine sand particles, it means that the antistatic agent is overflowing, and the antistatic performance period will be greatly shortened.
3. After cutting the table mat according to the required size, spread it on the table top. It should be flat and not warped. Such as edge warping will increase with the use time, the more serious the edge warping.
4. The table mat does not change color when exposed to sunlight or strong light.
5. It shall comply with the SGS inspection, and the hazardous and toxic gases and substances shall meet the standard requirements.
