Cleaning agent and cleaning process for aluminum alloy decorating part

Abstract

The invention discloses a cleaning agent for an aluminum alloy decorating part. The cleaning agent comprises the following components in parts by mass: 5-10 parts of sodium bicarbonate, 6-12 parts of sodium pyrophosphate, 6-10 parts of sodium triacetate, 5-10 parts of ethylenediamine tetraacetic acid, 5-10 parts of polyoxyethylene fatty acid, 5-10 parts of polyacrylamide, 3-6 parts of propylene glycol block polyether and the balance of water. The invention further discloses a cleaning process of the aluminum alloy decorating part, the aluminum alloy to be cleaned is placed in a groove type ultrasonic cleaning machine, any cleaning agent is poured into the groove type ultrasonic cleaning machine according to the dilution concentration of 10%, and the groove type ultrasonic cleaning machine is started to clean the aluminum alloy; cutting oil and ground powder on the surface of the aluminum alloy decorating part can be efficiently cleaned, meanwhile, corrosion and yellowing of products are effectively avoided, and the yield of the cleaned products is increased.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy cleaning, in particular to a cleaning agent and a cleaning process for aluminum alloy decorative parts. Background technique [0002] Nowadays, in the process of lightweighting of 3C electronic products such as mobile phones, the selection and requirements for materials are gradually increasing; aluminum alloy materials are gradually used in mobile phones because of their light weight, high strength and good texture after processing. Frame and camera trim. [0003] After the aluminum alloy decorative parts are CNC and polished, metal cutting oil and polishing liquid will remain on the surface, which needs to be cleaned to achieve a cleaning effect; however, aluminum alloys are relatively active due to their metal properties, so they can be used at high temperatures or in acidic and alkaline environments. , prone to chemical action, corrosion, or yellowing. [0004] At present, most of the...

AI Technical Summary

Problems solved by technology

[0003] After the aluminum alloy decorative parts are CNC and polished, metal cutting oil and polishing fluid will remain on the surface, which needs to be cleaned to achieve the cleaning effect; however, because the aluminum alloy is relatively active in metal characteristics, it can be used when the temperature is high or in an acid-base environment. , prone to chemical action, corrosion, or yellowing

[0004] At present, most of the cleaning agents for cleaning residual polishing fluid and metal cutting oil are strongly acidic or alkaline, which will cause damage to the product. Therefore, it is necessary to develop a cleaning agent and cleaning process for aluminum alloy decorative parts. While achieving the cleaning effect, reduce the damage of metal parts
