Problems solved by technology

On the one hand, the polishing powder particles remaining on the surface of the glass element will corrode the surface of the glass element. For example, the remaining polishing powder particles on the optical glass element after precision polishing are one of the key factors affecting the ability of the element to resist laser radiation damage; On the other hand, after the glass component is assembled on the electronic product, the polishing powder remaining on the surface of the glass component will seriously affect the stability and reliability of the electronic product, and even cause the electronic product to fail
[0003] The traditional methods of cleaning the surface polishing powder of glass components mostly use alkaline cleaning agents to clean the surface of glass components, but the use of alkaline cleaning agents for the removal of polishing powder on the glass surface is not effective; Environmentally friendly cleaning agent is used to clean glass components, but it needs to be cleaned repeatedly, resulting in a large amount of sewage and a lot of consumables; in addition, the operation of manual scrubbing is uncertain, which will inevitably lead to slight scratches on the surface of glass components, which in turn will affect the quality of the glass.

Abstract

The invention relates to a cleaning method for a glass element. The preparation method comprises the following steps: placing the polished glass element in an acidic cleaning solution for the first ultrasonic treatment and the second ultrasonic treatment in sequence, and then placing the polished glass element in an alkaline cleaning solution. In the cleaning solution, the third ultrasonic treatment is carried out, and finally, water washing and drying are carried out to obtain the cleaned glass element; wherein, the frequency of the first ultrasonic treatment is 10KHz~30KHz, and the frequency of the second ultrasonic treatment is 40KHz~70KHz. The cleaning method can effectively improve the cleaning efficiency of the glass element without damage to the glass element.

Description

technical field [0001] The invention relates to the field of glass cleaning, in particular to a cleaning method for glass elements. Background technique [0002] In the production process of glass elements, in order to reduce the roughness of the glass surface, the surface of the glass needs to be polished. In the polishing process, polishing powder is usually used to polish the surface of the glass, and a part of the polishing powder remains on the glass surface after polishing. On the one hand, the polishing powder particles remaining on the surface of the glass element will corrode the surface of the glass element. For example, the polishing powder particles remaining on the optical glass element after precision polishing are one of the key factors affecting the resistance of the element to damage caused by laser radiation; On the other hand, after the glass component is assembled on the electronic product, the polishing powder remaining on the surface of the glass compo...
