Ventilation pressurization type nano-silver melt-blown cloth diffusion device

Abstract

The invention relates to the field of melt-blown cloth, in particular to a ventilation pressurization type nano-silver melt-blown cloth diffusion device. The technical aim is to provide the ventilation pressurization type nano-silver melt-blown cloth diffusion device. According to the technical scheme, the ventilation pressurization type nano-silver melt-blown cloth diffusion device comprises a mounting rack, an operation control screen, a mounting workbench plate, a first ascending ladder, a second ascending ladder and the like; and the operation control screen is connected with the mounting rack. According to the invention, double-face spraying of melt-blown cloth is achieved; after folding is conducted, the two opposite faces of the inner side of the melt-blown cloth conduct repeated friction movement, so that a nano-silver solution on the surface of the melt-blown cloth can be evenly distributed to the surface of the melt-blown cloth; and airflow is enabled to penetrate through micropores of the melt-blown cloth through airflow pressurization, so that the nano-silver solution can be diffused into the micropores of the melt-blown cloth, and the nano-silver solution can be uniformly distributed in the outer surface of the melt-blown cloth and the micropores in the melt-blown cloth.

Description

technical field [0001] The invention relates to the field of melt-blown cloth, in particular to a ventilation and pressurized nano-silver melt-blown cloth diffusion device. Background technique [0002] Melt blown cloth is the core material of the mask. The melt blown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure, and good wrinkle resistance. The ultrafine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the melt blown cloth has good filterability, shielding, heat insulation and oil absorption. It can be used in air and liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials, oil absorption materials and wiping cloths and other fields. [0003] At present, in order to make the mask have a bactericidal effect in the prior art, nano-silver solution is used to s...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the bactericidal effect of the mask in the prior art, nano-silver solution is used to spray the melt-blown cloth, and then the melt-blown cloth is put into the mask processing process after spraying, but in the prior art, the melt-blown cloth is simply sprayed. The surface is sprayed, and the spraying effect is not good. The covering spraying method is used for spraying, and the nozzle coverage is limited. Usually, the nozzle is moved for spraying. The nano-silver solution is colorless. After spraying, it is impossible to observe whether the spraying is uniform with the naked eye. Some areas are not sprayed but cannot be observed. After spraying, it is impossible to ensure that every position on the surface of the entire melt blown cloth is wetted by nano silver solution. At the same time, only the surface of the melt blown cloth is wetted by nano silver solution after spraying, while the There is no nano-silver solution in the micropores, that is, the bacteria cannot be killed by the nano-silver solution when they enter the micropores of the mask melt-blown cloth, resulting in the bacteria remaining in the micropores and being inhaled by the human body, which will endanger human health. Question: Provide a ventilated and pressurized nano-silver melt-blown cloth diffusion device
