Problems solved by technology

[0002] Metal materials are damaged by the action of the surrounding medium, which is called metal corrosion. Metal rust is the most common form of corrosion. During corrosion, a chemical or electrochemical multiphase reaction occurs on the metal interface, causing the metal to turn into oxidation (ion ) state, which will significantly reduce the mechanical properties of metal materials such as strength, plasticity, and toughness, destroy the geometry of metal components, increase wear between parts, deteriorate electrical and optical physical properties, shorten the service life of equipment, and even cause fires, Catastrophic accidents such as explosions
[0003] At present, there are many ways to remove rust on the metal surface. The rust on the surface of different types of metal materials is different, so the methods of rust removal are also different. The commonly used surface rust removal methods include chemical immersion, electrochemical rust removal However, the chemical soaking method and the electrochemical rust removal method consume a large amount of chemical reagents, and the sewage process is complicated

Embodiment 1

[0037] refer to figure 1 , a metal plate surface cleaning method is characterized in that: comprising the following steps:

[0038] (1) Metal plates are cleaned and degreased, and mechanically derusted;

[0039] (2) Immerse the metal plate in the surface treatment solution, heat it to 80 to 90°C, and the treatment time is 30 to 40 minutes;

[0040] (3) Rinse the metal plate with deionized water for 0.5 to 1 minute;

[0041] (4) Immediately carry out neutralization treatment, immerse the metal plate in 0.5% sodium carbonate aqueous solution for 5 minutes;

[0042] (5) Passivation treatment, immerse the metal plate in the purification solution, heat to 80 to 90 ° C, and the treatment time is 5 to 10 minutes;

[0043] (6) Rinse the metal plate with deionized water, dry the surface of the metal plate and perform oil seal treatment.

[0044] Wherein, gasoline or acetone is used for cleaning and degreasing the metal plate in the step (1).

[0045] see figure 2 , figure 2sho...

Embodiment 2

[0055] Compared with the first embodiment, the second embodiment provides a specific grinding disc structure. The grinding disc 465 includes a grinding liquid supply port 4651, several circular teeth 4652 arranged concentrically, and several arc-shaped grooves 4653 connected with the grinding liquid supply port 4651. At the same time, the circular teeth 4652 have a distance of -4654 on a circle. There is a distance two 4655 between circular teeth 4652 corresponding to different diameters along the radial direction. Since the particles after grinding decrease from the inside to the outside, the distance between the distance one 4654 and the distance two 4655 can be reduced from the inside to the outside.

[0056] The present invention first cleans and degreases the metal plate, and performs mechanical derusting treatment; then immerses the metal plate in the surface treatment solution, heats it to 80 to 90°C, and takes 30 to 40 minutes; rinses the metal plate with deionized wate...

Abstract

The invention relates to a surface cleaning method and a cleaning device of sheet metal. The method comprises the steps of cleaning and removing oil from the sheet metal, performing mechanical derusting treatment, immersing the sheet metal in surface treatment liquid, heating to 80-90 DEG C, treating the sheet metal for 30-40min, flushing the sheet metal for 0.5-1min with deionized water, neutralizing the flushed sheet metal immediately, immersing the sheet metal in a 0.5% sodium carbonate aqueous solution for 5min, performing passivating treatment, immersing the sheet metal in purified liquid, heating to 80-90 DEG C for 5-10min, flushing the sheet metal with the deionized water, wiping up the surface of the sheet metal, and then performing oil seal treatment. At the same time, the invention further discloses the cleaning device for the mechanical derusting treatment of the surface of the sheet metal. Rusty spots on the surface of the sheet metal can be effectively removed by the cleaning method; micro scratches generated by the mechanical derusting treatment are treated; and at the same time, the method has no influence on the size, shape, surface roughness, luster and the like ofthe sheet metal.
