What is the difference between the active carbon mask and the general mask in the folding mask machine

With the development of industrialized cities, our living environment is facing severe pollution. We all know that environmental pollution has certain harm to human health, such as haze, dust, smoke and dust in the air are persecuting our health all the time. In order to protect our health, it has become a habit for us to wear masks when we go out, and the active carbon mask is also one of them. Next, I will introduce the difference between activated carbon mask and general mask.

The general mask is a kind of sanitary product, which is generally used to filter the air into the inlet nose by wearing it on the mouth and nose, so as to reach the appliance to block harmful gases, smells and droplets from entering and leaving the wearer's mouth and nose, and is made of gauze or paper, etc.

Activated carbon masks used to be mainly used in military affairs. They have been widely used since World War II. They are mainly used as anti-virus and anti biochemical weapons. The difference between them and other general masks lies in their primary structure and principle. Adding activated carbon to the filter data of masks is to use the adsorption of activated carbon to absorb toxic gases, which is commonly called filter type Yes, activated carbon masks.



1、 Adsorption principle of activated carbon

According to the different forces between the molecules of activated carbon and pollutants in the adsorption process, the adsorption can be divided into two categories: physical adsorption and chemical adsorption. In the adsorption process, when the force between the activated carbon molecule and the pollutant molecule is van der Waals force, it is called physical adsorption; when the force between the activated carbon molecule and the pollutant molecule is chemical bond, it is called chemical adsorption.

2、 According to these properties and operation principles of activated carbon, the mask made by the
mask manufacturer has the following characteristics:

1). Effectiveness of anti poison, deodorization, bacteria filtering, dust prevention, etc.

2). It is especially suitable for occasions containing irritant gases such as organic gases, acid volatiles, pesticides, sulfur dioxide and chlorine.

3). It can be used to avoid the dust below 5 microns that the general mask can not work and a variety of bacteria transmitted by the respiratory tract.

4). It can be used to isolate benzene, ammonia, formaldehyde, peculiar smell, malodor and other harmful gases in the air to ensure human health.
