Life's essential course to avoid static electricity

Winter has arrived, have you ever experienced being shocked by static electricity when taking off your sweater or opening car door? Recently, a video of a fire caused by static electricity while refueling has also attracted everyone's attention. In the video, a female driver ignited the nozzle due to static electricity while refueling, which is shocking. How to effectively prevent static electricity, let the community newspaper tell you some small methods.

Reasons for body to produce static electricity

When the human body moves, the skin and clothes between each other, as well as the clothes and clothes between each other, will produce electricity due to friction. And the soles of our shoes are usually insulated, so the static electricity generated by the friction between the woolen sweater and the body or clothes is stored in large quantities. When these static electricity encounters a conductor, it will be instantly released, and the "snap" sound will be produced. Overall, material is the most prone to static electricity, followed by mixed chemical fiber woolen cloth, and then in turn are leather clothes, sweaters, polyester, cotton T, and chiffon.

Where are you most likely to be shocked

Opening and closing doors, touching each other, touching dogs, will all make a snap sound. addition, touching with the tip of the finger is more painful than touching with the entire palm. The pain of the static electricity at the tip of the finger is due the high voltage discharge, because the contact area between the hand and the metal object is extremely small during discharge, so it will produce an instantaneous high voltage.

How to to prevent static electricity

1. Wear more pure cotton clothes: because cotton clothes produce less static electricity than wool and synthetic fiber clothes.

2. Wear woolen clothes fine metal wires: because the conductive metal wires can connect with the human body, so that the opposite charges produced between the two are neutralized.

3. Gofoot: only for indoor activities, and the indoors are relatively warm, otherwise you will catch a cold.

4. Wear anti-static shoes with conductive soles: static electricity generated will be continuously released.

How to properly discharge static electricity

1. Increase the contact area: if the charge has already accumulated on our body, as as the body is simply "grounded", the charge on the body can be released, such as washing hands, touching pipes, faucets, or other grounded metal. However, when discharging, remember to have a large area of contact with the conductor, such as touching with the palm of your hand, to prevent the instantaneous voltage (the reason has been explained above).

2. Hold a key to touch metal: if you are afraid of static electricity when opening the door in winter, you pinch the key to touch the door, and the contact point of the discharge will not be a certain point on your finger.

3. Use your knuckles to touch objects: because the knuckles have fewer nerve endings and lower pain.

4. Humidifier: the nemesis of static electricity.

5. Hand cream: Although effect is not the best, but in autumn and winter, the air is relatively dry, many boys and girls have the habit of applying hand cream, from a practical of view, hand cream is better.

The correct way to get out of the car

1. Keep holding the door frame when getting out of the car: make that your hand touches the metal door frame before getting out of the car, and you must keep in contact with it until you completely leave the seat.

2. If suddenly realize that you forgot to grab the door frame after getting out of the car, and you are full of static electricity, what should you do? You can hold metal part of the key with your hand, and then touch the car door with the tip of the key.

Special reminder: for car owners, it is especially important pay attention to releasing static electricity when refueling.
