Description

Removable formula wave type filter pulp

Technical Field

The utility model relates to a filter pulp technical field specifically is a removable formula wave type filter pulp.

Background

The range of filter cotton is relatively wide, and the filter cotton (filter screen) is commonly referred to as air filtration. The filter material of the filter cotton is divided into four types according to the difference of materials: synthetic fiber filter cotton, non-woven fabric filter cotton, glass fiber filter cotton and active carbon filter cotton. An adult requires approximately 19m3 of air per day to obtain the required oxygen therefrom. If the air of a working place of a worker contains a large amount of dust, the dust amount sucked into the lung of a person working in the environment is large, a plurality of harmful gases, liquids or certain metal elements can be adsorbed on the dust, the harmful gases, liquids or certain metal elements are taken into the deep part of the lung or adhered to the tube wall of a bronchus along with the breathing of the person to cause or aggravate various diseases of respiratory organs, when a certain amount is reached, the lung tissue can be caused to generate fibrosis lesion, the lung tissue is gradually hardened, the normal respiratory function is lost, and related diseases are caused, so that the mask can effectively prevent the diseases in the environment with poor air index, and the mask is one of filter cotton and can effectively filter dust particles in the air, so that the cleanliness of the sucked air is ensured.

The existing gas mask is matched with a plane filter cotton and an activated carbon tank, and an outer cotton cover is tightly buckled, so that the edge is sealed and isolated from air, and the air enters from the front side of the filter cotton and enters the activated carbon tank through a filter layer of the filter cotton. Although the tight buckling and pressing has the sealing effect, the volume of the filter cotton layer is compressed, the breathing resistance is increased, a wearer feels stuffy, the dust holding capacity of the filter cotton is reduced, the service life is shortened, and most of the filter cotton is fiber melt-blown cotton which has fiber lines and uneven surface, so that the air leakage is caused due to poor sealing performance of the filter cotton and the outer filter cotton shell.
