How to judge the pros and cons of anti-static mats? Now let's analyze it in detail:
(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), newly purchased table mat surface resistance 5*10^8 ohms or so, it is difficult to guarantee the validity period of 1 year and a half to 2 years.
(2) The surface should have no heavy odor, it should not be oily, no fine sand. If the oil is light or there is fine sand, it means that the antistatic agent overflows, and the antistatic performance is effectively shortened.
(3) The table mats are cut to the required size and laid on the table top. They should be flattened and not trimmed. If the edge is raised, it will increase with the use time, and the more serious the edge is.
(4) The table mat is exposed to sunlight or strong light and does not change color.
(5) The anti-static table mat should meet the SGS test, and the harmful toxic gases and substances meet the standard requirements.
