Problems solved by technology

[0002] With the acceleration of industrialization, the problem of air quality is becoming more and more serious. Indoor smog and dust pose a huge threat to people's health. Air purifiers have almost become a must-have household appliance for ordinary families, but they have the following disadvantages : 1) High cost: The price of brand purifiers on the market is generally more than 2,000 yuan, and the filter element will be replaced at least once a year in the later period, and the price is about 200 yuan; 2) Carbon dioxide hazard: the premise for the air purifier to achieve indoor purification effect is to close the indoor door The windows cannot be ventilated. During long-term use, the concentration of carbon dioxide will gradually increase with people's breathing, causing physical discomfort; 3) There are noise and power consumption problems

Embodiment 1

[0042] Put 2.4g of polyvinylpyrrolidone (PVP, molecular weight: 1 million) and 17.6g of ethanol in the Erlenmeyer flask, seal it with sealing tape, stir magnetically for 3 hours until the PVP is completely dissolved, and the solution appears uniform and transparent. Let it stand for 1 hour to obtain the mass concentration 12% spinning solution for use;

[0043] Take an indoor King Kong net window screen (size is 40cm×100cm, 0.4m 2 ), the diamond mesh window screen is cleaned up with water and dried. Such as figure 1 As shown, extract 5mL of the spinning solution with a 5mL syringe, install the needle on the syringe, and install the syringe with the needle in the cavity of the electrospinning device; connect one end of the zero potential line to the rear of the electrospinning device The shell is connected by soldering, and the other end is connected with the diamond mesh screen by soldering; hold the electrospinning device in hand, adjust the distance between the needle and ...

Embodiment 2

Abstract

The invention provides an indoor dust and haze preventing method based on a diamond gauze window. The indoor dust and haze preventing method comprises the following steps of curing a spinning solutionby an electrostatic spinning method in the processes of cracking in air, tensioning and fining, solvent volatizing and the like; using a diamond net window gauze with conductivity as a cathode for collecting nanometer fibers, and depositing the nanometer fibers at the surface of the diamond net window gauze to form a nanometer fiber film. Proofed by results in embodiment, the nanometer fiber filmhas the advantages that the filtering ability is very high; the diamond net window gauze attached with the nanometer fiber film can effectively block more than 70% of haze particles and more than 99%of dust particles from entering a room, and can still maintain more than 50% of air ventilating property and light transmission property. The indoor dust and haze preventing method has the advantagesthat the problem due to use of air purifiers is solved; the indoor air circulation and purifying can be realized at very low cost; the economic and environment-friendly effects are realized; the electric energy is completely not consumed, and the noise is avoided; the market application prospect is broad.
