Embodiment 1

[0026] The PES solution was stretched under the action of an electric field to form nanofibers, which were deposited on a polypropylene nonwoven fabric pulled forward at a speed of 2 m / h.

[0027] Polypropylene non-woven fabric is mostly used for the filling layer of the filter element. It is characterized by high strength, good high temperature resistance, aging resistance, UV resistance, high elongation, good stability and air permeability, corrosion resistance, sound insulation, moth resistance, and no poison. PES has good heat resistance, hydrolysis resistance, creep resistance, excellent dimensional stability, and outstanding flame retardancy. It is used in the fields of electronic machinery, automobiles, medical equipment, coatings, etc. Bubble electrospinning method can prepare PES nanofiber membrane with large specific surface area, which can cover most of the pore diameter of polypropylene non-woven fabric, so that the pore diameter of non-woven fabric is reduced, and...

Embodiment 2

[0029] Titanium dioxide is added to the PES spinning solution. Titanium dioxide has the advantages of high photocatalytic activity, stability, non-toxicity, many times of reaction and easy acquisition, which makes it a very potential photocatalytic material at present. Therefore, the titanium dioxide is adhered to the polypropylene non-woven fabric and attached to the screen window by the method of bubble spinning, so that the air can be exchanged and the purpose of degrading VOC and other pollutants can be achieved, thereby achieving the process of being discharged outside. degrades it. At this time, the screen window mostly appears in the haze weather or in the newly decorated living room.

Embodiment 3

[0031] Add nano-activated carbon to the PES spinning solution. Activated carbon is a very small carbon particle with a large surface area, and there are smaller pores in the carbon particle-capillary. This kind of capillary has a strong adsorption capacity, and due to the large surface area of ​​the carbon particles, it can fully contact with the gas (impurity).

[0032] Add activated carbon non-woven filter layer, which can absorb extremely small particles, so that the air containing harmful substances can be filtered through the filter material of the screen window before entering the room. This kind of filter screen window not only has the function of dust removal, but also has the characteristics of sterilization and deodorization. It can be widely used in the office environment to eliminate indoor odor and smoke; in the home environment, it can remove the human body odor in the bedroom, the bathroom odor, and the musty smell in the kitchen; A large amount of toxic and vo...

Abstract

The invention discloses a nano window screen which comprises a frame and gauze embedded on the frame. The gauze comprises a non-woven fabric overlaid layer formed by two layers of non-woven fabrics and at least one layer of nanofiber film arranged between the two layers of non-woven fabrics; each nanofiber film is formed by nanofibers in a crossed manner; pores with an aperture range of 0.1mu m to 0.5mu m are formed between the nanofibers. According to the nano window screen, the nanofibers which are special superfine fibers are used; the surfaces of the superfine fibers are provided with activated carbon particles with an adsorption effect. The superfine fibers have large specific surface areas and have more contact probability with particles and micromolecular harmful substances in air. The pores formed by the fibers in the crossed manner also show a nano-scale distribution range, and commonly, each nanofiber film with a thickness of 10mu m has the aperture range of 0.05mu m to 0.5mu m, and thus, the window screen can block particles with the particle size of being no less than 0.5mu m and the blockage rate is improved a lot. The thickness of each nanofiber film can be controlled to change the aperture range so as to implement filtering on smaller particles in the air.

Description

technical field [0001] The invention relates to a screen window, in particular to a nano screen window capable of filtering PM2.5 particles. Background technique [0002] At the beginning, the screen window was mainly used to prevent mosquitoes and wind. In addition, it could filter some hairy objects and sundries entering the room. The screen window is more popular in the market. Generally, the invisible screen window can adjust the spring force inside the yarn box by itself. The yarn box can be removed to increase force and reduce force, and some can automatically remove floating dust. Because it is made of metal, the screen window is heavy, and the installation process of the screen window is complicated. In the era of SARS and swine flu, the Ministry of Health has been advocating that windows should be opened frequently to breathe fresh air and air conditioners should be turned on less frequently. This shows that screen windows must be used if the whole family wants to...
