Principle of anti-static table mat and auxiliary method of floor mat
1. Working principle of anti-static table mat:
Install an anti-static table pad on the desktop, and then buckle one end of the anti-static grounding wire button on the surface, and the other end of the anti-static grounding wire is connected to the ground, so that the static electricity collected on the desktop can be discharged through the anti-static grounding wire.
The principle is as follows:
1. The green surface is for storage and absorption of static electricity around the desktop, and its resistance is 107~109Ωcm;
2. The black bottom surface is a conductor, and the resistivity is ≤106Ωcm. Because it is a conductor, it 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 grounding wire. In this way, the static electricity around the desktop can be discharged through this principle.
2. Auxiliary method of anti-static floor mat
1. Requirements for foundation ground:
a. The foundation ground can be terrazzo ground, porcelain ground, or wooden ground.
b. The ground should be level, without obvious unevenness, and the unevenness should be less than two thousandths.
c. The ground must have sufficient strength without sanding and shelling.
d. The ground should be dry.
2. Construction procedures and specific methods:
a. Use 120# gasoline or xylene to clean impurities on the ground (using a washing machine);
b. Copper or aluminum bars are used for ground accessories, just like copper bars with a thickness of 0.02mm and a width of 30mm. The number of bars shall be determined according to the actual requirements of the ground accessories, and the length and quantity of the copper bars shall be led to the ground at the same time;
c. After laying the grounded conductive net, clean and dry the ground, apply conductive glue, and dry for 20 to 30 minutes, until the hand is not sticky, 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;
d. The ambient temperature during construction should be no less than 25℃, and good ventilation should be required;
e. The electrical resistivity of the conductive glue is not more than 108Ωcm
