When your hand touches a plastic box, there is always static electricity

In winter, when the weather is dry, the friction of clothes or friction with plastic boxes will produce static electricity, and the phenomenon of electric discharge will occur when it touches metal or other objects.

The main reason for the static electricity generated on the surface of plastic products is that the special electrical properties of plastics are relatively special, and it is easy to carry electrostatic charges. In addition, in the process of manufacturing, processing, transportation, storage, etc., friction, collision, shearing and other operations can also generate static electricity, which further exacerbates this phenomenon. To eliminate static electricity on the surface of plastic products, the following measures can be taken:

1.Plastic products are made with antistatic materials, which reduces the possibility of electrification on the plastic surface. 2.

The use of antistatic packaging materials and tools in the manufacturing and transportation of plastic products reduces the generation of static electricity. 3.Spraying antistatic agents on the surface of plastic products can effectively eliminate surface static electricity.

4.Using a static eliminator, a plastic product is placed into the eliminator, and the static electricity on the surface is neutralized by the working principle of the eliminator. In short, static electricity is a common problem on the surface of plastic products, but static electricity can be reduced or eliminated through the above methods, so as to improve the quality and use effect of plastic products.

Physical elimination is employed.

It is the most commonly used method to eliminate the pre-cavity without changing the properties of the material and using the characteristics of the static electricity itself.

The generation of static electricity is as follows:

The object itself is generally considered to be electrically neutral, and when two materials with different chemical compositions or different physical states come into contact with each other, charge redistribution occurs on their respective surfaces. When two substances are reseparated, each material has an excess of positive or negative charge than before contact, and this form of charge is called static electricity.

Electrostatic phenomena are very common in the production, processing and use of polymer smart shirts. When plastic materials are rubbed, they are easy to carry static electricity, and the order of their charging is (positive) polyurethane, nylon, acetate, polypropylene, polyester, polyacrylonitrile, polyvinyl chloride, vinyl chloride-acrylonitrile copolymer, polyethylene, polytetrafluoroethylene (negative).

The magnitude of static electricity generated by a plastic can be expressed in terms of its surface resistivity or volume resistivity. Different types of plastic products tend to show different surface resistivity and volume resistivity. <>

When you rub your hands or plastic bags against each other, static electricity is generated by friction. Since the charge of your hand and the plastic hand are opposite, then the interaction law between the charges is that the same charge repels each other, and the different charges attract each other, so the plastic bag will often get on your hand.

In addition, there is a saying in physics about the properties of charged bodies, which is called that charged bodies can attract small and light objects, so the plastic bag itself belongs to small and light objects, so your fingers will naturally attract the plastic bag to attach to your hand.

That's why if you have static electricity on your hands, it will stick to the plastic bag, and that's it. For such reasons, in fact, if you stick a plastic bag on your clothes, there is also a chance that it will stick to your clothes, not only on your hands.

Rubbed plastic bags can also stick to walls or other objects. It's all for this reason.

This is the same principle that a charged glass rod (or rubber rod) can attract small and light objects.

If you still have any questions, please feel free to ask.

Is it that you are wearing a lot of electricity, and you already have a lot of electricity, and there will be static electricity when you come into contact with plastic.

Because plastic is an insulator, plus drying, when it loses or gains electrons, it can remain charged and generate static electricity.
