Problems solved by technology

However, manual brushing is prone to product chipping and cleaning blind spots, and the rate of product chipping and dirt after cleaning is still high. In addition, the efficiency of manual scrubbing is low. For small-sized products, such as camera glass on mobile phones, the required amount Customized fixtures for auxiliary cleaning, high production costs

Abstract

The invention relates to the technical field of glass cover plate cleaning, in particular to a glass cover plate cleaning agent and a cleaning method thereof, and the glass cover plate cleaning agentcomprises an acidic cleaning agent and an alkaline cleaning agent; the method comprises the following steps: putting the glass cover plate into an ultrasonic cleaning machine, firstly cleaning the glass cover plate for 2-6 minutes at the temperature of 40-80 DEG C by adopting the acidic cleaning agent, then cleaning the glass cover plate for 5-15 minutes at the temperature of 40-80 DEG C by adopting the alkaline cleaning agent, then washing the glass cover plate with water, and then drying the glass cover plate. According to the cleaning agent, by adopting the dispersing agent, small-particleimpurities adhered to the surface of the glass cover plate can be separated, fingerprints, dust, glass powder, grease and other organic and inorganic solid particles on the surface of the glass coverplate are effectively removed, and the cleaning effect is good. The cleaning method disclosed by the invention is particularly suitable for cleaning polished 2.5 D and 3D glass, can avoid a manual brushing process and use of a strong alkaline cleaning agent, and can improve the cleaning efficiency and the cleaning yield.

Description

technical field [0001] The invention relates to the technical field of glass cover plate cleaning, in particular to a glass cover plate cleaning agent and a cleaning method thereof. Background technique [0002] With the diversification of electronic products such as mobile phones and watches, the requirements for glass panel materials and processing are more stringent. Mobile phone glass is generally made of Corning materials, but the surface of this product is not resistant to ultrasonic cleaning of strong acid and strong alkali cleaning agents after shape processing, and it is prone to dense and fine scratches on the product surface, increased surface roughness, and even bluish defects on the entire surface. defect. At present, the existing technology generally adopts a high-alkali and high-chelating cleaning agent with an alkalinity greater than 1%, and ultrasonically cleans glass products for 90-240s at 55-75°C. ~60%. [0003] Moreover, the requirements for the surfa...
