The safety of anti static fluid, what are the measures for electrostatic protection

For the convenience of the narrative, the safety of the anti-static fluid is described here by taking the NAIR anti-static fluid as an example.

NALUT anti-static liquid is a water-based liquid, non-toxic, harmless, odorless, otherwise, environmentally friendly and safe, with good safety performance. According to the Food Sanitation Act, the test results are qualified, but the antistatic liquid contains organic substances, of course, it cannot be drunk, and it must be used with care according to the regulations.

When the anti-static liquid is applied to the workbench, the workbench has an anti-static function.

Nalut is a washable anti-static fluid, which will not lose its anti-static function even if rinsed with water or wiped with a damp cloth, while traditional anti-static liquid cannot be rinsed with water or wiped with a wet towel.

Direct contact should be avoided, and if it splashes on the **, it should be rinsed with water immediately. During storage and transportation, it should be waterproof and sunscreen, and it is strictly forbidden to turn it upside down. The retention period is one year.

I'm sorry, but I don't know about the safety of antistatic fluids. However, at room temperature and humidity, the anti-static durability of the anti-static liquid is valid for several months to more than one year, which can significantly reduce the surface resistance of plastic products, so that it reaches 10 to the 7th power to 10 to the 9th power ohm, antistatic is efficient and durable, non-toxic, in line with RoHS, and the compatibility with the resin is suitable, and does not affect the processing and use performance of the product.

Anti-static fluid is redundant.

1. Grounding: The equipment is grounded through metal wires with a cross-sectional area that meet the standards, and the personnel are grounded through bracelets, anti-static shoes and other measures.

2. Use anti-static materials: replace ordinary materials with static dissipative materials, such as anti-static mats and anti-static floors in anti-static work areas.

3. Lap (or jumper): electrically connect two or more independent metal conductors so that they are at roughly the same potential as each other.

4. Electrostatic shielding: using the Faraday cage principle, a closed conductor is used to shield the static power supply or products that need to be protected.

5. For insulators that can hardly leak static electricity, antistatic agents are used to increase the conductivity, so that static electricity is easy to leak.

6. Environmental humidification: spraying, sprinkling and other methods are used to increase the relative humidity of the environment to 60 to 70% to inhibit the generation of static electricity.

Static electricity is a kind of electric charge that is at rest or does not flow (a flowing charge forms an electric current). Static electricity is formed when the charge is gathered on an object or surface, and the charge is divided into two types: positive charge and negative charge, that is to say, the phenomenon of static electricity is also divided into two types, namely positive static electricity and negative static electricity. When the positive charge is gathered on an object, it forms positive static electricity, and when the negative charge is gathered on an object, negative static electricity is formed, but whether it is positive static electricity or negative static electricity, when the electrostatic object touches a zero-potential object (grounded object) or an object with a potential difference, the charge transfer will occur, which is the spark discharge phenomenon we see every day.

1. For the materials that are in contact with the electricity, the adjacent ones should be selected according to the live sequence and appropriately combined, so as to minimize the electricity.

2. In the design of production process and production equipment, try to achieve less contact area, less pressure, less contact times, and slower movement and separation speed.

3. In the most dangerous places, all electrostatic conductors should be grounded, especially the movable equipment or components should be grounded, and the electrostatic sub-conductors and electrostatic non-conductors should be indirectly grounded, and the connection must be firm and reliable, and the total grounding resistance between the earth and the earth should generally not be greater than 100 ohms.

4. Increase the relative humidity of the local environment to more than 50 to reduce the resistivity of the surface of some materials, and the specific degree of humidification should be determined by the actual conditions of the site.

5. Electrostatic conductor or electrostatic subconductor is used to replace electrostatic non-conductor.

6. For live materials, install an electrostatic moderator with a slower flow rate near the discharge port.

7. Personnel working in ** dangerous places should wear anti-static (conductive) shoes to prevent the human body from being electrified, and should be equipped with conductive ground. The "Coal Mine Safety Regulations" stipulates that personnel who come into contact with blasting materials above and below the mine shall wear cotton cloth or antistatic clothing, and it is strictly forbidden to wear chemical fiber clothing.

8. Add a small amount of appropriate anti-static additives to some materials to reduce their resistivity.

9. Using air ionization and electrostatic neutralization, static eliminators with different principles such as high-voltage power supply, induction or radiation can be used.

The most serious danger of static electricity is to cause ** and fire. Therefore, the electrostatic safety protection is mainly for the protection of ** and fire. These measures are also effective in preventing electrostatic shock and preventing static electricity from affecting production.

1) Control of environmental hazards.

In order to prevent the ignition of static electricity, measures to control the environment and fire danger can be taken to replace the combustion medium, reduce the concentration of the mixture, reduce the content of oxidant, etc.

2) Process control.

Process control is to limit and avoid the generation and accumulation of static electricity from the aspects of material selection, the limitation of friction speed or flow rate, the enhancement of electrostatic relaxation process, and the elimination of additional static electricity.

3) Grounding The main function of grounding is to eliminate static electricity on the conductor. Metal conductors should be directly grounded. In order to prevent spark discharge, the gap where spark discharge may occur should be connected and grounded so that each part of the site is equipotential with the ground.

4) Humidification In order to prevent a large amount of charge, the relative degree should be more than 50%; In order to improve the effect of reducing static electricity, the relative degree should be increased to 65%-70%; For polymeric materials with strong hygroscopicity, the relative humidity should be increased to 80% to 90% in order to ensure the effect of reducing static electricity. It should be noted that the method of humidification should not be used to eliminate static electricity on high-temperature insulators.

5) Antistatic additives.

Antistatic additives are chemical agents that have good electrical conductivity or strong hygroscopicity. Therefore, in highly insulating materials that are prone to static electricity, the addition of antistatic agents can reduce the volume resistivity or surface resistivity of the material to accelerate the leakage of static electricity and eliminate the danger of static electricity.

6) Static Eliminator.

Static eliminator is a device that can produce electrons and ions, due to the generation of electrons and ions, the electrostatic charge on the material is neutralized by the opposite charge, thereby eliminating the danger of static electricity.

Static eliminators are mainly used to eliminate static electricity on non-conductors. Although it may not be possible to completely eliminate static electricity on the charged body, it can be eliminated within a safe range.

I believe that many friends have been exposed to static electricity in their lives, but the hazards of static electricity and some protective measures may not be too clear, let's take a look at it together.

Hazards of static electricity

1. Static electricity can cause fire and fire, especially in petroleum, chemical, rubber, paper printing, powder processing and other industries.

2. Electrostatic shock may occur when the human body is close to a live object, or when the human body with static electricity is close to a grounded conductor or other conductors.

3. If the static electricity is not removed in the production process, it will often hinder the production or reduce the quality of the product, such as: the sieve hole is blocked, the textile yarn is entangled, and the handwriting of the printed matter is uneven; Semiconductor and electronic components are damaged or malfunctioned due to the discharge current, resulting in the scrapping of photographic films.

Protective measures against static electricity

There are many protective measures against static electricity, and the more common ones are grounding through bracelets, clothing, anti-static shoes and other measures; It is mainly the use of static dissipative materials to replace ordinary materials; Use closed conductors to shield static power sources or products that need to be protected; Antistatic agents are used to increase electrical conductivity, so that static electricity is easy to leak; Spraying, sprinkling and other methods are used to increase the relative humidity of the environment to 60 to 70% to suppress the generation of static electricity.
