3D Mask

2020 Jul 04

The three-dimensional design of the mask is consistent with the shape of the face, so as to eliminate the gap between the mask and the side, such as the nose, cheeks and chin, which cannot be achieved with ordinary masks.Three - dimensional masks are mainly duck - billed masks, folding masks and cup masks

Structure type:

Stereoscopic masks are the most widely used in our daily work.The structure of a three-dimensional mask should be divided into two parts. One is the main body of the mask, which can be simply understood as a mask shelf.The other is the filter material part, including the filter cotton used for dustproof and chemical filter box used for poison prevention.Therefore, for the selection of three-dimensional mask, some products of Guangjia provide you with the following convenience: you can use the same mask body, and when dust prevention is needed in the dust working environment, it is matched with the corresponding filter cotton, so that you wear a dust prevention mask;When it is necessary to prevent virus in a toxic environment, replace the filter cotton and install the corresponding chemical filter box, so that it becomes a respirator, or according to your work needs, provide you with more combinations

Efficiency of dust:

The dust resistance efficiency of a three-dimensional mask is based on its barrier efficiency for fine dust, especially for respirable dust under 5 micrometers.Because this size of dust can be directly into the alveoli, the impact on human health is the greatest.General gauze mask, its dust resistance principle is mechanical filtering, is when dust collision into gauze, through - layer upon layer barrier, will be some large particles of dust in the sand.However, some fine dust, especially those smaller than 5 microns, will pass through the mesh of the gauze and enter the respiratory system.Now there are some dust masks abroad, the filter material is composed of fiber filled with permanent static electricity, those smaller than 5 microns of respirable dust in the process of passing through this filter material, attracted by static electricity and adsorption in the filter material to capture the fine dust, really play the role of dust resistance.

Or degree:

Air, like water flow, flows first where there is little resistance.When the shape of the three-dimensional mask is not close to the face, the air hazards will also never close leakage into the people's respiratory tract.So, even if you choose the filter material again good mask.It doesn't protect your health.Many foreign regulations and standards stipulate that workers should be regularly tested for the tightness of non-woven masks.The purpose is to ensure that workers choose suitable non-woven masks and wear masks according to the correct procedures.

Comfortable wear requires small respiratory resistance, light weight, wear sanitation, easy maintenance.Then workers will be willing to wear them in the workplace and improve their productivity.There is no need to clean or replace the parts of the current maintenance-free masks. They are discarded when the dust is saturated or the masks are damaged, which not only ensures the hygiene of the non-woven masks, but also saves the time and energy for workers to maintain the masks.In addition, many masks adopt the arched shape, which not only ensures a good close fit with the face shape, but also keeps a certain space in the non-woven mask for comfort.
