In the future, anti-static clothing will have more applications
In most industrial processes, static charges accumulate, which may make people feel uncomfortable and even cause harm to the human body. Even in the process of loading, unloading and transporting flammable gas, liquid and dust, fire and explosion accidents can occur. In particular, there are potential hazards in the field of static electricity, such as chemical, petroleum, paint, plastic, pharmaceutical, food, printing, and electronic industries that are prone to static electricity hazards.
The resistivity of the human body is very low and can be regarded as a conductor. When the human body is wearing insulated shoes or standing on an insulated floor, the human body can be charged by contact. The human body can also be charged by induction, and can conduct conduction through contact with other charged bodies. The common reason is the need for anti-static clothing. The common static electricity generation process of the human body is as follows:
(1) The process of people getting up from chairs or wiping walls (the initial charge separation occurs on the outer surface of clothes or other related objects, and then the human body is charged by induction).
(2) People walk on insulated floors made of high-resistance materials (the initial charge separation occurs between the shoes and the floor, and then, for conductive shoes, the human body is charged through charge transfer; for insulated shoes, the human body is charged by induction) .
(3) Static electricity when the jacket is taken off. This occurs when the outer layer of the clothing and the inner layer of the clothing are in contact with electricity, and the human body is charged through charge transfer or induction.
(4) Pour out the liquid or powder from the container held by the person (the liquid or powder will take away the polar charge and leave the same amount of opposite charge on the human body).
(5) Contact with charged materials. For example, when sampling highly charged powders.
Although the accumulation of static charge can be reduced by increasing the air humidity, it is not easy to keep the air humidity above 65%-70% in the increasingly dry and dry global climate. Therefore, it will become a trend for workers and even ordinary people to wear anti-static clothing.
