How to check the effectiveness of anti-static rubber sheet after laying
Method for detecting anti-static rubber sheet by surface resistance tester:
The surface resistance tester is an instrument for testing the surface resistivity of an object. It can perform simple and repeatable tests of electrical conductivity, surface resistance, and insulating surface properties. The test range is between 10 to the 3rd power and 10 to the 12th power, 10 to the 3rd power to 10 to the 5th power is the conductive range, and the green light shows: 10 to the 6th power to 10 to the 11th power to prevent ) Static electricity range, yellow light display; 10 to the 12th power or more is the insulation range, red display.
The effective range of the anti-static rubber sheet is: the surface resistance of the anti-static rubber sheet (green layer resistance) is 10 to the 6th power of 10 to the 9th power of the anti-static layer; the back resistance of the anti-static rubber sheet (black resistance) is Between 10 to the 3rd power and 10 to the 5th power is the conductive layer.
During the use of the anti-static rubber sheet, the surface resistance tester is often placed on the surface of the anti-static rubber sheet and then the use button of the surface tester is pressed.
When the surface resistance instrument shows a yellow light, the anti-static rubber sheet is effective, when the light shows a red light or a green light, the anti-static rubber sheet is invalid;
Use the same method to test the back of the anti-static rubber sheet. When the light shows a green light, the anti-static rubber sheet is effective. When the light shows a yellow light or a red light, the anti-static rubber sheet fails; when the surface of the anti-static rubber sheet When the resistance and the back resistance meet the standards at the same time, it is considered as qualified.
