Mobile phone plate stamping oil how to clean?

At present, there are two main materials for mobile phone medium plate: aluminum magnesium alloy medium plate and stainless steel medium plate. Processing technology is generally used by stamping technology. Because the stamping process in order to ensure the quality of the metal surface and prolong the service life of abrasive tools, stamping oil needs to be used to lubritate and cool the stamping process. At present, the stamping oil used on the market is mostly used to mineral oil, synthetic resin and some polymer lubricants and other raw materials. These substances are easy to form oil film on the metal surface, causing greater difficulty to the rear cleaning.

At present, in the industry, medium plate cleaning, there are mainly the following problems:

1, the use of solvent-based cleaning agent, neither environmental protection nor safety

2, the use of water-based cleaning agent, there are the following problems:

A. The safety of Al-Mg alloy is insufficient, which is easy to cause corrosion of Al-Mg alloy in the cleaning process

b, cleaning performance is insufficient, there is stamping oil residue on the workpiece surface, after high temperature baking will form yellow oil spots

C, cleaning agent residue, in high temperature baking, residual water stains and cleaning agent react with metal surface at high temperature to form an irremovable watermark.
