Anti-static sticky mat laying method
Method for laying sticky mat
1. Basic ground requirements:
1 The ground should be flat, no obvious unevenness, and the unevenness should be less than 2/1000.
2 The basic ground can be water-grinding ground, porcelain ground, and wooden ground.
3 The ground needs to have sufficient strength, no sanding and shelling.
4 The ground needs to be dry.
2, anti-static sticky mat construction procedures and specific methods:
1 Clean the impurities on the ground with 120# gasoline or xylene (with a washing machine).
2 copper strip or aluminum strip is laid on the ground. For example, the thickness of the copper strip is 0.02 mm and the width is 30 mm. The length and number of the copper strip should be determined according to the actual requirements of the ground laying. The end of the laid copper strip should be at the same position as the ground.
3 After laying the grounding conductive mesh, clean and dry the floor, apply conductive adhesive liquid, and dry for 20-30 minutes until the hands are not sticky. The bottom surface (black surface) of the anti-static dust floor is operated the same (only one conductive adhesive is applied once), then the anti-static dust-proof floor mat is bonded to the ground, and then the heavy-duty roller is used for rolling 5 times to make the surface of the anti-static rubber sheet neat. Straight, can be used after 48 hours at room temperature.
4 During the construction period, the ambient temperature shall not be lower than 25 degrees Celsius, the humidity shall not be higher than 25 degrees Celsius, and the ventilation is good.
5 Conductive glue liquid resistance coefficient is not more than 108 Ωcm, peeling strength Kg / 2.5cm.
The conduction between the gaps can be achieved by applying a conductive adhesive liquid or sticking it to the surface of the copper strip.
The surface resistance of an antistatic dust pad is the ratio of the DC voltage between two points on the surface of the material to the current flowing through the material, expressed in ohms. Surface resistivity or volume resistivity is often used to describe the electrical resistance properties of a material. The surface resistivity is simply the measured resistance value between the two electrodes on the same surface. The electrode shape and the resistance value are combined to calculate the resistance value per unit area. The antistatic dust mat volume resistivity refers to the resistance value through the material thickness, and the unit is Ω·cm. The general surface resistance can be measured with a surface resistance meter.
