Grounding method of anti-static table mat
1. Laying method of anti-static table mat:
Lay an anti-static table mat on the desktop, and then buckle one end of the anti-static grounding wire button on the surface, and the other end is connected to the ground conductor, so that the static electricity collected on the desktop can be discharged through the anti-static grounding wire. The principle:
1. The green surface is for storage and absorption of static electricity around the desktop, and its resistance is 107---109 Ωcm;
2. The black bottom surface is a conductor ≤106Ωcm, because the conductor can quickly discharge the absorbed static electricity;
3. One end of the grounding wire is connected to the anti-static table pad, and the other end is connected to the ground. Therefore, the static electricity is discharged to the ground smoothly through the connection wire, so that the static electricity around the desktop is discharged through this principle.
2. Laying method of anti-static mat
1. Requirements for foundation ground:
①The foundation ground can be terrazzo ground, porcelain ground, or wooden ground. ②The ground should be level, without obvious unevenness, and the unevenness should be less than two thousandths. ③The ground should have sufficient strength without sanding and shelling. ④The ground should be dry.
2. Construction procedures and specific methods:
① Use 120# gasoline or xylene to clean the impurities on the ground (using a washing machine); ② Use copper or aluminum strips for floor laying, such as copper strips with a thickness of 0.02mm and a width of 30mm, and the number of strips is determined according to the actual requirements of the floor Length and quantity, lead one end of the laying copper bar to the ground at the same place. ③After laying the grounded conductive net, clean and dry the ground, apply conductive glue, and dry for 20-30 minutes, until the hands are not sticky, the operation of the bottom surface (black surface) of the anti-static mat is the same (apply conductive glue once), and then Glue the anti-static rubber sheet to the ground, and then roll it with a heavy roller 5 times to make the surface of the anti-static rubber sheet neat and straight. It can be used after 48 hours at room temperature. ④ During construction, the ambient temperature should not be less than 25 degrees Celsius, the humidity should not be greater than, and the ventilation should be good. ⑤The electrical resistivity of the conductive glue is not more than 108Ωcm, and the peeling strength is Kg/2.5cm. ⑥ Conduct conduction between the gaps, just use conductive glue, or paste on the surface of the copper strip.
