Precautions for purchasing anti-static mats
Anti-static mats are mainly made of a variety of processes using conductive materials, static dissipative materials and synthetic rubber. The top layer is a static dissipative layer of about 0.3-0.5 mm thick, and the bottom layer is a conductive layer of about 1.5-1.7 mm thick. The anti-static table mat has the advantages of long-lasting use, good anti-acid, anti-alkali and anti-chemical flux properties, and is truly wear-resistant and easy to clean.
The anti-static workbench countertop adopts anti-static fireproof board and anti-static mat. Some workbench is stainless steel. The desktop needs to be covered with an anti-static mat. The mat is connected to the ground through the connecting line to achieve the effect of diarrhea and static electricity. The anti-static table mat adopts the production process of the bottom layer as a conductive layer, so that the anti-static table mat plays a good anti-static and conductive effect.
What should I pay attention to when purchasing anti-static mats?
1, the color is unchanged, the table mat is exposed to sunlight or strong light.
2, harmful toxic gases, substances meet the requirements of the specification, should comply with SGS testing.
3, should be flattened, the table mat is cut on the table top according to the required size, not on the table, such as the edge will increase with the use of time, the more serious the edge.
4, anti-static mat should not be oily light without fine sand, if the oil light or fine sand, the appearance should not have a heavy smell, it means that the anti-static agent overflow, anti-static performance will be greatly shortened.
5, friction voltage <200V, static decay time <2, the newly purchased anti-static table mat surface resistance is about 510^8 ohms, whether it meets the anti-static index specified by the specification (resistance is 110^6 ohm~~110^9 Ohm. It is difficult to guarantee the validity period of one and a half to two years.
