Electrophobia makes us wary of reaching out our hands. Where does the static electricity that bothers everyone come from? How can we prevent it? Today and everyone to understand the static electricity of those things ~

01【 What is static electricity? 】

Static electricity is an electric charge that is at rest or does not flow. Static electricity is not static electricity, but macroscopic electricity that temporarily stays somewhere.

In daily life, this phenomenon is not uncommon: when you take off your clothes to sleep at night, you often hear a crackling sound in the dark, and accompanied by blue light; When you brush your hair in the morning, your hair often floats with the comb and becomes more and more chaotic. When the door handle and the water tap are "electrocuted", they often make a sound of "snap, snap, snap", which is the static electricity that occurs in the human body.

In the case of good insulation of the friction material (that is, there is no iron chain connected to the ground), these charges cannot be lost, and they will accumulate. And because the capacitance of the insulation is very poor, resulting in a high voltage although the amount of charge is not large. (Because the electricity is equal to the capacitance times the voltage, the electricity is not large, but the capacitance is also small, so the voltage is very high.)

Wearing clothes made of chemical fibers is more likely to generate static electricity, while cotton clothes produce less. And because the dry environment is more conducive to the transfer and accumulation of charge, people will feel the static electricity on their bodies in winter.

Under different humidity conditions, the electrostatic voltage generated by human activities is different. In the dry season, the static electricity of the human body can reach several thousand volts or even tens of thousands of volts. Experiments have proved that the human body does not feel uncomfortable when the electrostatic voltage is 50,000 volts, and there is no life danger when taking 120,000 volts of high voltage static electricity. Therefore, in general, the static electricity carried by the human body in winter will not affect the physiological function of the human body, please rest assured.

02 [What are the dangers of static electricity?]

Explosion and fire

Explosion and fire are major hazards of static electricity. Although the electrostatic energy is not large, it is easy to discharge because of its high voltage. When the charged body and the uncharged or low electrostatic potential objects are close to each other, if the potential difference reaches 300 V or more, there will be a spark discharge. If the spark energy of electrostatic discharge has reached the smaller ignition energy of the surrounding fuel, and the concentration of the fuel in the air reaches the explosion limit, combustion or explosion will occur immediately.

The harm of electrostatic shock to human body

Hazards to pregnant women

Persistent static electricity can cause the pH value of human blood to rise, increase the excretion of calcium in urine, reduce the blood calcium, the health hazard of pregnant women is relatively large, static electricity can cause the level of progesterone in pregnant women to decline, so that they are easy to feel fatigue, irritability and headache, so it is necessary to take appropriate precautions.

Danger to the baby

First of all, it will increase the alkaline concentration of the blood, and reduce calcium, which is a big taboo for infants and young children who are in the growth and development period. Also, electrostatic adsorption of a large number of dust contains a variety of viruses, bacteria and harmful substances, they will make the baby's skin spot inflammation, weak resistance of the baby may even cause bronchitis, asthma and arrhythmia and so on!

On the skin

In the environment of TV, computer and microwave oven for a long time, it is often possible to have enlarged pores, dry skin, red spots, skin itching and other symptoms. The incidence rate of facial diseases such as facial erythema and pigmentation of office white-collar workers who operate computers every day is much higher than that of those who do not use computers, which is due to the static electricity generated by the computer screen attracts a lot of suspended dust, causing facial stimulation. This is especially true for people with sensitive skin.

Harm to the output and quality of products, equipment and production environment

Static electricity can make the powder deposition in the production, block the pipeline, screen, etc., resulting in poor transmission and system pressure, overpressure can lead to equipment rupture. In the process of storage and transportation of plastics and other products, electrostatic discharge will lead to product melting, bonding, discoloration and even decomposition, deterioration, scrap and so on. Electrostatic discharge energy may cause damage to silicon components in computers, production control instruments, and safety control systems, resulting in misoperation and accidents.

03【 Basic measures to prevent electrostatic hazards 】

Elimination of static electricity by human body

1. Eliminate static electricity with metal objects

Metal objects are good at eliminating static electricity. Just take metal items such as keys, coins, nails, etc. with you, and when you touch the items with static electricity, gently touch the metal items and the static electricity will be released.

2. Use an antistatic spray

Antistatic spray is a product that can remove static electricity very well. Simply spray some antistatic spray on your clothes or carpet, and it will create a protective film that reduces the likelihood of static electricity.

3. Use antistatic clothing

Some specially designed clothing can help reduce static electricity generation. These clothes are usually made of antistatic fibers, which can reduce friction between the clothes and the body and reduce the generation of static electricity.

6. Use antistatic gloves

The hand is one of the main places where static electricity is generated. Therefore, using antistatic gloves can help reduce the generation of static electricity. These gloves are usually made of antistatic materials, which can reduce the friction between hands and objects and reduce the generation of static electricity.

The above method can be free from static electricity in life, and the nervous nerves caused by static electricity will also alleviate a lot

Production static elimination

The principle of preventing electrostatic damage is to control the generation of static electricity and prevent the accumulation of static electricity. Controlling the generation of static electricity is mainly to control the process and rationally select the materials used in the process. Preventing the accumulation of static electricity requires trying to accelerate the leakage and neutralization of static electricity, so that static electricity does not exceed the safe limit.

Process control method is to take measures in the process flow, equipment structure, material selection and operation management to achieve the purpose of limiting the generation of static electricity or controlling the accumulation of static electricity. The specific methods are as follows:

1) Limit the transmission speed: reduce the friction speed in liquid transportation or the flow rate of liquid materials in the pipeline and other working parameters, which can limit the generation of static electricity.

2) Accelerate the escape of electrostatic charges: including the use of buffers, when conveying liquid materials, before the charged liquid enters the storage tank through the pipeline, it first enters the buffer "buffer" for a period of time, so that most of the charge escapes during this period, thus greatly reducing the charge brought into the storage tank; The liquid injected into the storage tank should stand for a period of time before measuring, sampling and other work, so that the accumulated charge to the wall, liquid level concentrated and discharged into the ground; To eliminate impurities, oil products should avoid mixing between water, air and other impurities and oil products and different oil products in the production and transportation.

Ruizer antistatic masterbatch is more easily dispersed than the previous direct addition of liquid, powder or paste antistatic agent to achieve the ideal antistatic effect.

The antistatic masterbatch is resistant to high temperature, has good performance, and will not decompose during spinning or injection molding. The addition amount is low, the effect is fast, and the effect is lasting. According to the processing characteristics of different resins, different high-efficiency antistatic agents are selected to meet the requirements of various processing industries.
