Ask for help with anti static detection methods?? A specific and simple approach is best described a

If there is a specific situation, if there is a situation, you can explain the situation (environmental conditions and the requirements to be met), so that there is a corresponding method.

What can be discussed together.

A resistance value of 10 to the 6-12th power is antistatic.

In general, a resistance value of 10 to the 1st to the 2nd power is superconductive. A resistance value of 10 to the 3-5th power is conductive. The resistance value of 10 to the 6-12th power is antistatic, and the smaller the resistance value, the better the antistatic effect.

A resistance value of 10 or more to the 13th power is insulation. The antistatic agent is added as a transparent liquid, the product is colorless and transparent, and it does not affect the transparency of the product after use, and it is easy to adjust the color and does not affect the color of the product.

Common sense of life. In people's daily life, sometimes due to clothing, climate, friction and other reasons, often cause the body to accumulate static electricity, and when suddenly touching metal, it will suffer the pain of electric shock, and it can even cause some psychological pressure when it often occurs at a certain stage. If you temporarily avoid touching the iron, you may accumulate more electrical charges on your body, and sooner or later you will receive a greater electric shock.

In the house, static electricity may be generated when the carpet rubs against the soles of the shoes, and it can also become electrified outside the house due to wind. At this time, be careful when entering and exiting the iron door, as your hands may be beaten by electricity. After encountering this situation repeatedly, the following methods can be taken to avoid electric shock:

When touching an iron door, do not touch the iron door directly with your hands, but use your hands to grasp a string of keys in your pocket (usually this will not be shocked), and then use the tip of a key to touch the iron door, so that the electricity on your body will be discharged and you will not be shocked.

Principle: The pain of the discharge on the hand is due to the high-voltage discharge, because the hand and the iron door are suddenly in contact with a very small area during the discharge, resulting in instantaneous high voltage. If you take out the key in your pocket, first hold the key in a large area (a bunch of keys themselves can not transmit much charge so there will be no electric shock at this time), and then use the tip of a key to contact the large conductor, this Gao Wu Hui, the discharge contact point is not a point on the hand, but the tip of the key, so the hand will not feel pain.

The anti-static ground resistance is usually less than 10.

1. The surface resistance value of the ground or floor mat should be between 105-1010, and the friction voltage value should be less than 100V.

2. The resistance value of the electric group of the wall is generally required to be between 5 104 and 109.

3. The surface resistance value of the working table or pad should be maintained between 106 and 109, and the friction voltage should be less than 100V; The resistance of the ground system is in the range of 106-108.

4. The resistance requirement of the working chair facing the caster is between 106 and 108, and it cannot exceed this specified value.

5. The friction voltage of anti-static overalls, dust-free caps and anti-static gloves should be less than 300V, and the friction voltage of the soles of anti-static shoes should be less than 100V.

6. Wrist strap connection cable resistance 1m; The system resistance should be between 1-10m when wearing the wristband. Heel strap (shoe harness) System resistance 105 108 .

7. The resistance of the logistics vehicle facing the wheel system is 106-109.

8. The surface resistance value of logistics transmission equipment such as material boxes, turnover boxes, PCB racks, etc. is 103 108; The friction voltage is less than 100V.

9. The friction voltage of the packaging bag and the ant burning packaging box should be less than 100V.

10. The comprehensive resistance of the human body is 107 108. <

Test with an electrostatic tester.

The electrostatic tester is suitable for measuring the electrostatic voltage (potential) of live objects, such as conductors, insulators, and the electrostatic potential of the human body. It can also measure the liquid level potential and test the performance of anti-static products. It is a non-contact portable electrostatic field tester with a built-in microprocessor, which is accurate in measurement, but lightweight and easy to use.

Methods for testing static electricity:

1. All anti-static grounding wires use 6m multi-strand copper core insulated wires, and each floor or appropriate section is switched with copper bars or switches above 40A, and the gate knife is connected to the main line to facilitate inspection and maintenance.

2. The anti-static grounding cable should be well insulated from the equipment shell, workbench iron frame, work lamp stand, etc., to prevent short circuit, lap connection or broken skin connection.

3. In the segmented copper bar or switch"Trunk end"and lay another inspection line. (i.e.), each workshop set up 2 3 checkpoints, fixed, clearly marked.

4. Measurement: use pointer multimeter and resistance file.

The resistance between each anti-static test point and the anti-static ground wire is 5 15, and the ideal should be 0But the actual measurement is 2m, the resistance of the wire from the test point to the summary point is +6m, and the sum of the resistance of the wire from the summary point to the measured point, this value is about 5-15 and basically unchanged, if the measurement result tends to infinity, it is a broken wire for the anti-static ground wire or the measurement line, which should be repaired in time.

The resistance between the anti-static grounding wire and the ground of the equipment, this resistance value is composed of the line resistance of the anti-static ground wire itself + the line resistance of the ground wire itself + the ground resistance between the two wires. However, due to the degree of dryness and wetness of the ground, especially the ground current, the magnitude, direction, and frequency between the two grounding wires are changing from moment to moment.

And it mainly determines the measurement results, so it can only be measured with a pointer meter, and its value is normal from more than a dozen euros to hundreds of k, which only means that there is no short circuit or open circuit between the two places.
