What are the main electrical functions of anti-static shoes?

Static electricity is an objective natural representation, which occurs in many ways, such as touch, conflict and so on. Electrostatic protection skills, such as electronic industry, petroleum industry, weapon industry, textile industry, rubber industry, Xinghang and military areas, seek to reduce the loss of electrostatic formation.

 

What are the ways to eliminate static electricity? Next, Shuncai anti-static shoes will talk to you about ways to eliminate static electricity:

 

Although the occurrence of static electricity will not present any big doubt, it will still have a little conflict with people's body. Then how to eliminate static electricity and what are the methods to eliminate static electricity?

 

Physical or chemical methods can be used:

 

Usually it can be summed up as "relying on the ground";

 

Second, rely on "eliminator" (install eliminator);

 

Three rely on "anti-static agent" (add antistatic agent);

 

Four rely on "shielding".

 

On some special occasions, we can also rely on anti-static shoes, anti-static clothes and other commodities.

 

The air ionization skill of electrostatic eliminator is increasingly used to control or neutralize static charges in key occasions. Its principle is that the electrostatic eliminator made of air electric ion generator is actually enough to make the air conductive to eliminate static electricity on insulators and insulated conductors.

 

Air ions are molecules that get or lose electrons in the air. Ions exist in normal air, but are deleted after filtration and air conditioning. When ions apply high voltage to top objects, they lead to radiation, that is, corona discharge.

 

The main electrical functions of anti-static shoes are:

 

1、 Baotou anti impact function

 

The steel impact hammer with regular component shall be used for impact test. When the Baotou is impacted, the gap height under the Baotou shall be less than the regular value, and the Baotou shall not show any penetrating crack in the direction of the test axis. It is worth noting that the rules for the weight, specification, impact height and structure of the experimental machine of the impact hammer are different in the specifications of various countries, which should be distinguished in the practical test.

 

2、 Anti puncture function

 

The testing machine is equipped with a pressing plate, which is equipped with a test nail. The test nail is a head with the top cut off, and the hardness of the nail head shall be greater than 60HRC. Place the sole sample on the chassis of the testing machine so that the experimental nail can pierce through the outsole. The experimental nail pierces the sole at the speed of 10 mm / min ± 3 mm / min until the penetration stops, and record the maximum force required. Select 4 points on each sole for the experiment (at least one point is at the heel), the distance between each point is not less than 30mm, and the distance from the edge of the insole is more than 10mm. The bottom with anti sliding block shall be pierced between blocks. Two of the four points shall be tested at an interval of 10-15 mm from the edge line of the planting bottom ridge. If the humidity will affect the results, immerse the sole in deionized water at 20 ℃± 2 ℃ for 16 ± 1H before the test.

 

3、 Electrical functions of conductive shoes and anti-static shoes

 

After adjusting the shoe in a dry and wet atmosphere, the clean steel ball is filled into the shoes and placed on the metal probe equipment. The resistance between the front two probes and the third probes is measured by the regular resistance tester. Generally, the required resistance of conductive shoes should not be greater than 100k ohm; The required resistance of anti-static shoes shall be between 100k ohm and 100m ohm.
