Preparing method for electrostatic type air purifier dust collecting plates

Abstract

The invention relates to a preparing method for electrostatic type air purifier dust collecting plates. The preparing method comprises the steps that 1, polypropylene plastic plates are subjected to surface oxidation processing through a potassium permanganate / sulfuric acid solution, and then acid pickling, deionized water cleaning and stoving are conducted; 2, the polypropylene plastic plates are immersed into an aniline solution and a hydrochloric acid solution for processing for 10-30 min and dropwise added with an ammonium persulfate solution under the stirring condition with the temperature being 5-15 DEG C, and the stirring reaction lasts for 18-30 hours; the polypropylene plastic plates are taken out, cleaned and dried in the air at the room temperature, and polypropylene plastic plates with a conductive material on the surfaces are obtained; and 3, the obtained polypropylene plastic plates are overlapped in an up-down mode and arranged in the direction of the conductive material in a staggered mode, and the two ends of each polypropylene plastic plate are connected through conducting wires or conductive plates. The preparing method for the electrostatic type air purifier dust collecting plates is mild in condition, safe and environmental friendly, adopted polyaniline is used as the conductive material on the surfaces of the plastic plates, the cost is low, and safety and environmental protection are achieved; the dust collecting plates are good in dust collecting effect and long in service life, and the electrostatic dust collecting plates can play a role in an air purifier effectively.

Description

technical field [0001] The invention belongs to the field of preparation of dust collecting boards, in particular to a method for preparing dust collecting boards of electrostatic air cleaners. Background technique [0002] In recent years, with the increasing outdoor air pollution, especially PM2.5 particulate pollutants have attracted people's attention, the demand for indoor air purification is increasing. In order to solve the problem of indoor air pollution, various air purification technologies have emerged as the times require, but there are still many technical problems to be solved when some new technologies are applied to practice. Therefore, the traditional adsorption technology and the electrostatic dust collection technology for a single pollutant are still the main technologies for purifying indoor particulate pollutants. Other new technologies need to strengthen the study of the synergistic effect of multiple technologies and improve the purification efficienc...

Problems solved by technology

However, there are also some disadvantages, such as electrical breakdown and leakage between the metal plates, which will generate ozone; and the dust collection efficiency will be reduced due to the wide spacing between the plates.

[0006] (3) At present, the dust collection plate of electrostatic air purifier has been developed from the traditional metal collection plate to the plastic display channel containing electret material. The dust collection plate of the plastic display channel containing electret material is coated with conductive paint Or apply a conductive plate to make the plastic wall conductive. At present, the shielding cost and filtration efficiency still need to be improved
