technical field

The invention belongs to the technical field of mask recycling, and in particular relates to a mask recycling processing device and a processing method thereof.

Background technique

A mask is a sanitary product used to filter the air entering the mouth and nose and block particles, droplets, viruses, etc. from entering the mouth and nose. Taking medical surgical masks as an example, the mask structure includes an outer layer of non-woven fabric to prevent liquid splashing and large particles; a middle layer of electrostatic melt-blown layer, which uses electrostatic adsorption to effectively block tiny particles, especially particles or droplets that carry nano-scale viruses. To achieve effective blocking of particles such as viruses; the inner non-woven fabric is used to block exhaled water vapor. The filtering effect of the mask mainly depends on the electrostatic adsorption of the intermediate meltblown layer. During the use of the mask, due to the deposition of particles and droplets, especially the influence of exhaled water vapor, the electrostatic adsorption of the meltblown layer is greatly attenuated, or even completely disappeared, and the mask's ability to filter out viruses is significantly reduced.

While achieving the above two requirements, it is necessary to avoid the damage of the microstructure of the mask.

At present, masks have become a necessity for people's daily protection. However, their use time is only about 4 hours, and the consumption rate is extremely fast.
