Metal construction member with aluminium powder sprayed on surface

Abstract

The invention relates to a metal construction member with aluminium powder sprayed on surface. The metal construction member with the aluminium powder sprayed on surface comprises a structure containing the metal construction member and the aluminium powder and a structure of the metal construction member with the aluminium powder sprayed on surface, wherein the metal construction member can be iron and alloy material of iron. The inner surface of an infrared radiation heating device is aluminium alloy or titanium alloy which can reflect infrared radiation, thus most of energy of the infrared radiation can be absorbed by iron material and alloy of the iron, therefore, heating speed is fast, energy utilization rate is high, and no harmful substance can be produced in the whole process, thereby being extremely environmentally friendly. No pollution is produced in a coating process, operating cost is low, energy is saved, coating efficiency is high, application range is wide, and anticorrosion capacity of the metal construction member is more than twice of that of the traditional metal construction member prepared by hot galvanizing.

Description

technical field [0001] The invention relates to a metal component whose surface is sprayed with aluminum powder, which relates to the technical field of metal anticorrosion, in particular to the technical field of coating aluminum powder on the surface of objects with infrared radiation, and is applied to the anticorrosion of metal components. Background technique [0002] At present, the industrial methods for completing hot-dip galvanizing technology at home and abroad mainly include wet hot-dip galvanizing, Wheeling thermal method, Sendzimir method, etc. Although these methods have certain advantages, the main performance is that the processing cost is low, the reliability is good, and the coating The toughness is strong and the protection is comprehensive, but the coating hot zinc needs pickling and alkali washing, which will cause serious pollution, and their energy consumption is very large, it takes a long time to complete the galvanizing, and the one-time investment i...

[0002] At present, the industrial methods for completing hot-dip galvanizing technology at home and abroad mainly include wet hot-dip galvanizing, Wheeling thermal method, Sendzimir method, etc. Although these methods have certain advantages, the main performance is that the processing cost is low, the reliability is good, and the coating The toughness is strong and the protection is comprehensive, but the coating hot zinc needs pickling and alkali washing, which will cause serious pollution, and their energy consumption is very large, it takes a long time to complete the galvanizing, and the one-time investment is large, especially It is fuel oil and coal heating that use non-renewable resources. A large amount of coal will seriously pollute the environment, and the energy efficiency is relatively low. Therefore, the application scale of these heating methods to complete metal anti-corrosion methods in our country is limited.
