Abstract

The invention relates to a double-laser derusting method. The double-laser derusting method comprises the following steps that cleaning derusting is conducted on a rusted contamination layer of a to-be-processed portion of metal electrical equipment through a pulse laser device with the wave length being 10.6 [mu]m; after cleaning derusting is completed, the to-be-processed portion is subjected touniform passivation through a passivation laser device with the wave length being 1.06 [mu]m, and a compact oxidation film layer is formed on the to-be-processed portion. The double-laser derusting method can conduct short-time efficient derusting on the corroded rusted electrical equipment and conduct uniform passivation on the surface of the equipment to delay metal corrosion.

Description

technical field [0001] The invention relates to the technical field of electric equipment maintenance, in particular to a double-light laser rust removal method. Background technique [0002] The electric power industry is the basic industry of the national economy. The safe production of electric power is related to thousands of households, economic development and social stability. However, because most of the electrical equipment is exposed to the outdoors all the year round, affected by environmental and climatic factors, many equipments have rusted metal parts, which has buried serious safety hazards for the production of enterprises. As a mountainous province, Guizhou is located at a low latitude, and the Tropic of Cancer runs through the middle of the region. Most of the region is rich in heat and rain, and its sugar factories and wineries are widely distributed, which intensifies the corrosion and rust of electrical equipment. [0003] There are three factors relate...
