Abstract

The invention discloses an ultrasonic bright cleaning agent for an aluminum case workpiece of a mobile phase battery. The ultrasonic bright cleaning agent comprises the components in percentage by weight as follows: 0.1-0.4% of potassium hydroxide, 1-7% of sodium tripolyphosphate, 1-4% of sodium pyrophosphate, 1-6% of sodium silicate pentahydrate, 0.1-2% of ethylene glycol monobutyl ether, 1-5% of activator (Y-71), 1-6% of activator (Y-90), 0.1-1.0% of activator (QYL-252C), 0.5-2% of JFC, 1-3% of NP-6, 1-2% of defoamer and the balance of deionized water. The preparation method comprises the following steps of: firstly, adding calculated and weighed deionized water into a stainless steel reaction kettle, starting a stirrer and controlling the rotating speed at 60rpm; then, sequentially adding the calculated and weighed solid raw materials into the reaction kettle; at least stirring each raw material for 10 minutes; then sequentially adding liquid raw materials calculated and weighed into the reaction kettle slowly; stirring while adding; and continuously stirring till the liquor is the uniform maize-yellow liquor.

Description

technical field [0001] The invention relates to an ultrasonic cleaning agent for aluminum workpieces, in particular to an ultrasonic bright cleaning agent for mobile phone battery aluminum shell workpieces that can completely remove dirt on the workpiece, ensure the cleanliness and brightness of the workpiece surface and has a long service life, and its preparation method. Background technique [0002] Metal cleaning is to use corresponding process equipment and process conditions to remove the dirt on the surface of the metal product workpiece with a specific solution, so that the product meets the technical requirements of the design, such as ultrasonic cleaning, steam cleaning, high pressure cleaning, ozone-UV Cleaning, ion beam cleaning and plasma cleaning, etc. For example, the aluminum shell of a mobile phone battery needs to be ultrasonically cleaned during processing. There are always two technical problems in the existing ultrasonic cleaning agent for the aluminum ...
