Embodiment

[0028] A method for making an anti-smog nano window screen, the method steps are as follows:

[0029] (1) Preparation of electrospinning solution

[0030] Add polyamide 6 particles into a formic acid solution with a concentration of 98%, and stir at room temperature to completely dissolve the polyamide 6 particles to form an electrospinning solution with a polyamide 6 mass concentration of 13%;

[0031] (2) Electrospinning

[0032] Use the electrospinning device to spray the above prepared electrospinning solution on the PET polyester fiber mesh substrate, and form a layer density of 1.25g / m2 or 2.5g / m2 on the PET polyester fiber mesh substrate. The nanofibrous membrane has an average fiber diameter of 217nm and a surface pore diameter of 234nm.

[0033] The above electrospinning device adopts the DT-200 electrospinning machine produced by Dalian Dingtong Technology Development Co., Ltd.

[0034] When the electrospinning device is working, the voltage of the high voltage ge...

Abstract

The invention provides a haze-proof nano window screen manufacturing method. The method comprises the steps that polyamide 6 particles are added into a formic acid solution with the concentration ranging from 92% to 99% and are stirred at room temperature to be completely dissolved, and an electrostatic spinning solution with the polyamide 6 mass concentration being 13% is formed; an electrostatic spinning device is utilized for spraying the prepared electrostatic spinning solution on PET polyester fiber net window screen basic materials, and a layer of nanofiber membrane is formed on the PET polyester fiber net window screen basic materials; nanometer titania is sprayed on the nanofiber membrane. The haze-proof nano window screen manufacturing method has the advantages that the nanofiber membrane can effectively filter out various respirable fine suspended particles such as dust (containing PM2.5), coal dust, smog, fiber impurities and pollen in the air, indoor air is kept clean, and human health is facilitated; the nanometer titania can resolve hazardous substances in air into innocuous substance under the action of light, and the purposes of controlling bacterial reproduction and purifying air are achieved.

Description

technical field [0001] The invention relates to the technical field of window screens, in particular to a method for manufacturing anti-fog and haze nano window screens. Background technique [0002] Window screen is a gauze installed on a door or window, specifically a mesh used to prevent mosquitoes and other small insects from disturbing. Most of the common window screens on the market are made of nylon or glass fiber and other materials, and the common ones are white, green and blue window screens. [0003] With the rapid development of modern industry, urban house building and road construction, vehicle exhaust emissions, and tree felling are becoming more and more serious, resulting in the air being often filled with pollutants such as dust and harmful particles, especially fine particles such as PM2.5 in the air in recent years. The concentration of the content in it is getting higher and higher, which directly endangers human health. [0004] For residents living i...
