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 method for cleaning a glass element. The preparation method includes the steps that a polished glass element is firstly placed in an acid cleaning fluid for the first ultrasonic processing and the second ultrasonic processing in turn; then the glass element is placed in an alkaline cleaning fluid for the third ultrasonic processing, and finally a cleaned glass element isobtained through water-washing and drying; and the frequency of the first ultrasonic processing is 10 KHz-30 KHz, and the frequency of the second ultrasonic processing is 40 KHz-70 KHz. The method for cleaning the glass element can effectively improve the efficiency of cleaning the glass element and has no damage to the glass element.

Description

technical field [0001] The invention relates to the field of glass cleaning, in particular to a method for cleaning glass elements. Background technique [0002] In the production process of glass components, in order to reduce the roughness of the glass surface, the surface of the glass needs to be polished. During the polishing process, the surface of the glass is usually polished with polishing powder, 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 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 compon...
