Principle of use of anti-static table mat
1. Requirements for the foundation floor The requirements for the foundation bottom surface can be water milled bottom surface or porcelain bottom surface.
The ground needs to be flat, 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 storing and absorbing static electricity around the desktop. Its resistance is 10 to the 7th power-10 to the 9th power Ω, and the black bottom surface is a conductor ≤ 10 to the 6th power Ω/cm, because the conductor can quickly absorb the static electricity Static discharge, one end of the grounding wire is connected to the anti-static table mat, and the other end is connected to the ground, so the static electricity is smoothly discharged to the ground through the grounding wire, so that the static electricity around the desktop is discharged through this principle.
The method of using the anti-static table mat is to lay an anti-static table mat on the desktop, and then button one end of the anti-static grounding wire on the surface, and connect the other end to the conductor leading to the ground, so that the static electricity collected on the desktop can be grounded through the anti-static The line is let out.
3. Construction procedures and specific methods Use 120# gasoline or toluene to clean the magazine on the ground (use a cleaning machine to lay copper or aluminum strips on the ground, such as copper strips with a thickness of 0.02mm and a width of 30mm, and the number of strips is based on the actual requirements of the ground laying To measure the length and quantity, while leading the other end of the copper strip to the ground.
After the grounding grid is laid, clean and dry the ground, apply conductive glue, and let it dry for 20-30 minutes until the hands are not sticky. The anti-static rubber sheet is bonded to the ground, and then rolled 5 times with a heavy roller to make the surface of the anti-static adhesive flat, and it can be done after 48 hours at room temperature.
During construction, the ambient temperature shall not be less than 25°C and the temperature shall not be greater than and the ventilation shall be good.
The resistivity of the conductive glue is not more than 108Ω, and the peeling strength is KG/2.5cm.
The surface of the copper strip that can be coated with conductive glue and can also be pasted
