The material of the iphone-shaped apple mobile phone mark is 304 stainless steel, SUS304 for short, and the current processing and cleaning process comprises the following steps: punching, coarse grinding by a chemical mechanical polishing machine, flushing, fine grinding of a nano silica sol plane, flushing, repeating for 3 times (alkaline ultrasonic soaking and cleaning, water washing, acidic ultrasonic soaking and cleaning), water washing, drying and assembling. And (3) the silica sol with the particle size of 80-100 nanometers adopted in the fine grinding process is polished to be mirror-surface bright within 10-20 min.
However, the nano-sized silica particles are strongly bonded to the matrix by complicated physicochemical actions, and the colloid formed after hydrolysis is extremely difficult to clean. The prior alkaline cleaning agent MC-131 and the acidic cleaning agent MC-431 have the following problems: 1. the cleaning time is too long, and the alkaline and acidic ultrasonic circulating soaking cleaning time needs more than 1 h; 2. the yield is low, the residual silica sol is not completely cleaned, and when the flashlight is irradiated and checked under strong light, the surface of the apple mark sometimes shows, a large area of the apple mark is not cleaned, and the apple mark is extremely stubborn and is difficult to clean, so that the yield is only 51%; due to the two reasons, the efficiency of the existing cleaning and processing process of the mobile phone apple marker is low, and the productivity is influenced. The customer is in urgent need of improving the yield and reducing the cleaning time.
Therefore, the development of a cleaning agent with short cleaning time and high yield after cleaning is a problem which is always concerned in the industry.
