Problems solved by technology

[0003] At present, there are mainly several structural types of electrostatic precipitators. One directly uses copper and aluminum metal sheets. This kind of dust remover has obvious dust removal effect, but it is prone to surface discharge or sparking under high voltage conditions, and at the same time releases heat energy. , easy to cause fire and insufficient safety, so it is generally used in the industrial field; the other uses a polymer film as the base material to print a conductive ink layer, and then covers a layer of polymer film to form a "sandwich" structure. The purification efficiency is high, the amount of ozone generated is far lower than the international standard, and the occurrence of undesirable phenomena such as ignition and arcing is completely avoided
However, this new type of dust removal sheet has no public literature reports and studies in terms of substrate selection, appearance design, ink performance requirements, and large-scale production methods.

Abstract

The invention discloses an industrial production method for an electrostatic dust collection sheet and relates to the technical field of air purification. The industrial production method comprises asubstrate pretreatment step, a printing step, a drying step, a coating step and a cutting step. By selecting a PET coiled material as a substrate, a strip-like ink pattern is printed to the substrate,a PET film coats the dried substrate, the substrate is laminated by a laminating machine and is then tailored to obtain the electrostatic dust collection sheet. The industrial production method for the electrostatic dust collection sheet is simple in process, easily available in raw material, low in cost and high in efficiency.

Description

Technical field [0001] The invention relates to the technical field of air purification, and more specifically to an industrialized production method of an electrostatic precipitator. Background technique [0002] At present, a new type of air purifier that uses high-voltage electrostatic dust removal is gradually being favored by the market. Compared with traditional filter air purifiers, this type of equipment has the outstanding advantages of higher dust removal efficiency, the filter is easy to disassemble and wash, and can be repeated use. This new type of air purification device is composed of wind wheels, dust collection modules, housings, motors and other components. The main components of the dust collection module are the positive and negative electrostatic precipitators. [0003] The current electrostatic precipitator mainly has several structural types. One directly uses copper and aluminum metal plates. This kind of dust removal film has obvious dust removal effect, b...
