Flat mask specifications

Flat mask is divided into: 2 layers of non-woven masks, three non-woven mask, four activated carbon masks.

Size specifications: 18 9 adults) 15 9 children)

Flat mask raw material

2 layers of masks: non-woven, nose ribs, ear hanging.

3 layers of masks: non-woven fabrics, nose ribs, ear hanging, filter paper.

Activated carbon masks: non-woven fabrics, nose tendons, ear hanging, filter paper, activated carbon filter paper.

Classification of masks

There are many ways, usually I according to its structure and working principle, divided into two categories: air filter masks and gas supply masks.

Air filter type masks, or simply filter-type masks work is to make the air containing harmful substances through the mask filter evolution after being inhaled.

Air supply masks refer to clean air sources that are isolated from harmful substances, and are delivered to human faces via a catheter to the face of a human body by means of a dynamic action such as an air compressor, a compressed cylinder device, etc.

Filter mask is the most widely used in daily work of a large category, the following details of the selection of such a mask and the use of conditions. The structure of a filter masks should be divided into two parts, one is the main body of the mask, can be simply understood as a mask for its mask; the other is the filter part, including dust for the filter cotton and chemical filtration Box and so on. Therefore, the choice of the use of filter-type masks, and some of the production of wide products to provide you with the following convenience, that you can use the same mask the main body, when the dust in the operating environment needs dust, coupled with the corresponding Filter cotton, so you put on a dust masks; when you need to fight in a toxic environment, replace the filter cotton, the device with the corresponding chemical filter box, so it has become a protective mask or according to Your work needs to provide you with more combinations.

Introduction of the filter

Protective masks of the filter, mainly divided into two categories, namely, dust and anti-virus category. The role of harmful aerosols, including dust, fumes, droplets, gas and toxic vapors by the filter material adsorption, blocking and not being inhaled.

Masks of the filter

For a good protective mask of the filter, should have the following three conditions, one mask and the user's face close to the case of good filtering efficiency, the second is the small respiratory resistance, the third is the user feel comfortable. Dust-proof masks filter material has a variety of materials, including ordinary fabrics, animal hair, non-woven fabrics. At present in the national standard is a very popular synthetic electrostatic treatment of non-woven materials.

Gauze mask structure and the adhesion of the human face is very poor, many of my great harm to the tiny particles will be through the mask and the face of the gap into the respiratory tract to the lungs, the filter is generally more mechanical fabrics, this filter to To achieve high resistance to dust, the only way is to increase the thickness, and increase the negative effect of the thickness of the user to feel a lot of breathing resistance, feeling uncomfortable. And the electrostatic treatment of non-woven fabrics can not only block large dust particles, and attached to the surface of the electrostatic charge can be electrostatic attraction will be small dust adsorption, to achieve a high dust efficiency. And the thickness of the filter is very thin, greatly reducing the user's respiratory resistance, and feel comfortable, so as to achieve the above mentioned a good filter of the three necessary conditions. With a good filter material, with a scientific design of the mask structure, it constitutes an efficient high-quality masks can make you feel easy to use, comfortable, and can really protect your health.
