Embodiment 1

[0018] Embodiment 1: in the preparation method of this embodiment, the material selected as the metal electrode plate is a 0.50mm 316L stainless steel sheet, and a common degreasing cleaning agent composed of nitric acid and nonionic surfactant is used to carry out pre-degreasing cleaning, After rinsing, dry it with compressed air, then immerse it in an aqueous solution of acid or salt of a high-valent metal oxide with oxidizing properties (such as a commercially available chromium salt passivator solution) for 5 minutes at room temperature or under heating, then rinse and dry it In this way, the metal ions in the high-valent metal oxides are reduced by soaking or spraying the dust-collecting board whose surface has been degreased to form low-valent oxides or hydroxides containing hydroxyl (-OH) on the surface of the dust-collecting board. substances, thereby forming a nano-scale oxide protective film with a higher oxidation potential, that is, a passivation film, on the surfac...

Embodiment 2

[0021] Embodiment 2: This embodiment is roughly the same as the embodiment of Embodiment 1, but the materials used are different. In the manufacturing method of this embodiment, the material selected as the metal electrode is 0.45mm AL7075 aluminum alloy sheet, using The common degreasing cleaning agent composed of phosphoric acid and non-ionic surfactant is used for pre-greasing cleaning, after rinsing, it is blown dry with compressed air, and then immersed in the chromium-free aluminum alloy passivator of the following specifications for treatment, and then rinsed and blown dry :

[0022] CeCl3 44g / L

[0023] H2O2 13%

[0024] NaOH 0.1mol / L

[0025] water balance

[0026] Temperature 35-45°C

[0027] Time 25 minutes

[0028] The aluminum alloy electrode plate after the passivation treatment can be immersed in an organic solvent (ether or acetone, etc.) with a content of 0.1-15% perfluorooctylethyltrimethoxysilane at room temperature for several seconds to tens of minute...

Abstract

The invention provides a method for anti-contamination treatment on the surface of dust-collecting plates of electrostatic air purifiers. The method comprises the following steps: cleaning and degreasing the metal dust-collecting electrode plates, and then passivating them; using the hydroxyl activity on the nano-passivation layer to The group further undergoes a heating condensation reaction after hydrolysis with perfluorocarbon siloxane or perfluorocarbon chlorosiloxane, and finally forms a firm 2-10 nanometer perfluorocarbon stain-resistant film on the dust collection plate, and at the same time Almost does not affect the original electrostatic field strength.

Description

【Technical field】 [0001] The invention relates to cleaning and maintenance of an electrostatic air purifier or device, in particular to a treatment method for anti-contamination of the surface of a dust collecting plate. 【Background technique】 [0002] In recent years, as people have become more and more aware of the hazards caused by air pollution, more and more air purifiers or purification devices have been used in various fields. High-voltage electrostatic air purifiers and purification devices are gradually being used in various places because of their high one-pass purification rate under low wind resistance. However, this relies on high-voltage static electricity to ionize the air, so that particles such as dust and bacteria that are ionized and charged under the action of high-voltage static electricity are generally difficult to be cleaned or blown off after being adsorbed on the dust-collecting electrode plate. Therefore, it is indeed necessary to develop a surfac...
