How to make anti-static mats to be durable
Principle of use of anti-static mat:
1. Requirements for the foundation ground The requirements for the foundation bottom surface can be terrazzo ground, porcelain mat, and wooden floor.
The ground should be level, without obvious unevenness, and the unevenness should be less than two thousandths.
The ground has sufficient strength without sanding and shelling.
The ground is dry.
2. The green surface is for storage and absorption of static electricity around the ground. Its resistance is 10 to the 6th power of 10 to the 9th power Ω, and the black bottom surface is for the conductor ≤ 10 to the 6th power Ω/cm. Because the conductor can quickly absorb the static electricity One end of the discharge and grounding wire is connected to the anti-static ground pad, and the other end is connected to the ground. Therefore, the static electricity is smoothly discharged to the ground through the grounding wire, so that the static electricity around the ground is discharged through this principle.
Three, construction procedures and specific methods Use 120# gasoline or toluene to clean the impurities on the ground (using a washing machine to pave the ground with copper or aluminum bars, such as copper bars with a thickness of 0.02mm and a width of 30mm, the number of bars is based on the actual requirements for laying on the ground To determine the length and quantity, and lead the other end of the copper strip to the ground.
After laying the grounding guide 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 floor mat is the same (apply conductive glue once), and then Glue the anti-static rubber sheet to the ground, and then roll it with heavy rollers 5 times to make the surface of the anti-static rubber even and flat, and it will work after 48 hours at room temperature.
During construction, the ambient temperature should not be less than 25℃, and the temperature should not be greater than and good ventilation.
The electrical resistivity of the conductive glue is not more than 108Ω, and the peeling strength is KG/2.5cm.
The surface of the copper strip can be pasted with conductive glue
