When the weather is dry in winter, when I get up and comb my hair in the morning
Hair is often fluttered with a comb
Often when you take off your clothes
Hear the crackling sound

The finger just touched when the meeting shook hands
A shiver of &hellip that is convenient for electricity;
A lot of people think it's normal.
It is not known that it exists.
What is the hidden danger of security

At the gas station, a woman is at the mouth of the tank
Pull the clothes around.
Then the hand was extended to the gas gun
Fire ball at the moment of the junction of the tank

You don't think it's just an example
There are many similar events.
Why many cities are in succession
No self-help refueling, and it's known at last.

In addition to the gas station, at home
It may also cause an electrostatic explosion!!!
case
A 78 year old man with a gas explosion caused a large area of burns in the head and hand.
According to the investigation, the explosion is probably due to the aging of the LPG pipeline at home, resulting in the leakage of LPG in the air, plus the old man wearing the chemical fiber fabric in the morning, resulting in strong static electricity. The two contacts cause the explosion.

Seemingly inadvertent static electricity
It's going to have such a big impact
In this dry season in autumn
The body's static electricity can reach thousands of volts and even tens of thousands of volts

The experiment proved that the electrostatic voltage of 50 thousand volts
There is no feeling of discomfort in the human body
There is no life danger with 120 thousand volt high voltage static electricity
So, static electricity in the body of the body in the winter
It doesn't affect the physical function of the human body

But in the chemical industry
Most media have flammable and explosive properties
In the process of production, transportation, storage and use
Often produce and accumulate static electricity

If these charges can't be released in time
Gradually accumulate to a certain degree
Very easy to occur electrostatic discharge
Ignite flammable and explosive gas, liquid vapor, or
Suspended dust and air formed
A combustible mixture, causing a fire or even an explosion.
Chemical static protection in chemical industry
For chemical enterprises
The main objective of electrostatic safety protection
I'm going to make it popular with you today
On the protection of static electricity

Basic measures to prevent the harm of static electricity
You
The principle of preventing electrostatic hazards is to control the generation of static electricity and prevent the accumulation of static electricity.
The control of static electricity is mainly the material used to control the process and to choose the process.

1. process control method
It is to take measures in the aspects of technological process, equipment structure, material selection and operation management to achieve the purpose of limiting the occurrence of static electricity or controlling the accumulation of static electricity.
(1) limiting the speed of transport: reducing the velocity of friction in the liquid transport or the flow rate of the liquid material in the pipe can limit the generation of static electricity.
Accelerating electrostatic charge dissipation:
Including the use of buffer in the delivery of liquid material, the charged liquid into the tank through the pipeline before entering the buffer in the &ldquo buffer; ” for a period of time, make the most of the charge dissipation during this period of time, thereby greatly reducing the charge into the storage tank;
In order to make the charge of the accumulative charge to the wall and the surface of the liquid, the liquid of the injection tank should be fixed for a period of time.
To eliminate impurities, oil products should avoid mixing water, air, and other impurities with oil products and different oils in production and transportation.
The elimination of additional source static: such as the bottom liquid flow spray, water flow into the container by mixing, liquid or powder body into the air or gas bubbles and dust in the hopper or silo, the impact of liquid or powder mixed stirring etc..
4. Select the suitable material to eliminate the static electricity.
Properly arrange the order of material input: in some stirring process, proper arrangement of feed can reduce the harm of static electricity.

2. electrostatic shielding method
Electrostatic shielding, which is about to shield the conductor near the electrostatic body, in order to reduce the danger of electrostatic discharge and prevent the effect of electrostatic induction.
It can be screened as a whole, and can also be shielded according to the needs. It can be used as a network shield or a plate shield. But it is important to note that shielding does not eliminate electrostatic charge.
3. electrostatic leakage method
The so-called leakage is to remove the static electricity. The leakage method includes the methods of grounding, humidification, adding antistatic agent, coating conductive coating and so on.
4. electrostatic eliminator
Electrostatic eliminator is an effective device to prevent insulator from being charged. It is divided into 3 types: radiation type, external power supply and self inductance.

Measures to prevent the live charge of the human body
You
1. human grounding
In the place where the static electricity is harmful, we should pay attention to dress, wear antistatic clothes, shoes and gloves, and not wear chemical fiber clothes.
In the place where the human body must be grounded, the metal grounding rod should be installed — — the power dissipation device, the staff should be exposed to the grounding rod by hand at any time. In the case of work, the staff can wear the earthing wristbands.

2. ground conductance
The working ground of a special dangerous place should be conductive or cause electrical conductivity.
3. safe operation
A cloth or cloth scrubbing object that is not allowed to be made with chemical fiber materialsOr the ground. In the work, we should try not to carry out the activities that make the human body live. In a place where static electricity is in danger, metal items that are not related to work are not allowed.

Like a little editor

All kinds of electricity or electricity.
It is not sour and refreshing.
If you are like me
