An external rust removal and repair device for a power distribution cabinet and its application method

Abstract

The invention discloses a power distribution cabinet external rust removal repairing device and a using method thereof, and belongs to the field of rust removal repairing. According to the scheme, before paint spraying, a circle of annular non-rust area is arranged on a power distribution cabinet shell in advance, and therefore in the rust removal process, a small number of rust chippings which are attached to the edge of a paint layer are reduced; after an annular area is formed, lubricating oil is smeared on the annular non-rust area, and a gap between the paint layer and the metal surface can be sealed; when the rust area is treated, the situation that the rust chippings enter the gap between the paint layer and the metal surface can be reduced through a lubricating oil layer; after anedge strip area is arranged on the annular non-rust area, the treated area is arranged to be in a protruding shape, and then paint spraying is carried out; and through cooperation of the edge strip area and a protrusion, the attachment effect between paint and the metal surface can be improved, and therefore the possibility that the dried paint falls off is reduced, and bubbling is not prone to occurring between the dried paint and the metal surface.

Description

technical field [0001] The invention relates to the field of derusting and repairing, and more specifically relates to a device for derusting and repairing the exterior of a power distribution cabinet and a method for using the same. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final equipment of the power distribution system. Power distribution cabinets are collectively referred to as motor control centers. , The motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load. This level of equipment should provide protection, monitoring and control for the load. [0003] Rust removal refers to the method of applying various means to remove metal surface rust. Metal rust is metal oxide....

AI Technical Summary

Problems solved by technology

[0003] Rust removal refers to the method of applying various means to remove metal surface rust. Metal rust is metal oxide. When the power distribution cabinet is in use, it is usually coated with anti-rust paint on its surface. During long-term use, Partial dry paint will fall off in the power distribution cabinet, and the metal on the surface will be corroded. If the rust on the surface cannot be treated technically, it may cause further corrosion of the power distribution cabinet, thereby reducing the service life of the power distribution cabinet. service life

[0004] In the prior art, when derusting the power distribution cabinet, the loose dry paint on the part of the power distribution cabinet is usually artificially torn off, and the rusty part is polished, and finally sprayed on the polished part with spray paint. The polished part is protected again, but its disadvantages are also obvious. The residual rust stains may not be cleared during the grinding process, so that the residual rust stains will be covered on the paint layer and the metal during the painting process. between the surface, so that the metal surface will continue to oxidize, and there will be a gap between the newly added paint layer and the metal surface, so that after long-term use, there will be bubbles between the paint layer and the metal surface, so that the dry The paint is easy to crack and fall off, so that the metal surface is exposed to the air, making the metal surface more likely to be rusted
