Example Embodiment
[0033] Example one:
[0034] This example provides five proportioning schemes, and each component and proportioning content are shown in Table 1. After the proportioning is completed, the components are mixed and stirred evenly at room temperature to obtain the water-based cleaning solution for glass substrates provided by the present invention.
[0035]
[0036] Table 1
[0037] This embodiment further provides a method for cleaning glass substrates using the above water-based cleaning solution. First, the above cleaning solution is added to an ultrasonic cleaning machine, the temperature is raised to 40°C, the glass substrate is placed in the cleaning solution, and the ultrasonic is turned on to clean About 3 minutes. Then, the cleaned glass panel is cleaned in 40°C deionized water under the same cleaning conditions for about 3 minutes, and then dried by an air knife.
[0038] It is assumed that the cleaning effect of the cleaning agent is evaluated from the following aspects:

Example Embodiment
[0055] Embodiment two:
[0056] In this embodiment, the above-mentioned inorganic alkaline substance is replaced with KOH, and the remaining substances remain unchanged, and 7 solutions are provided, each of which has a different content of each component, to detect the cleaning ability of the water-based cleaning solution for glass substrates in this embodiment. Each component and its percentage content are shown in Table 3:
[0057]
[0058] table 3
[0059] Similarly, the present invention also provides a method for cleaning a glass substrate using the above-mentioned water-based cleaning solution.
[0060] First, the above-mentioned cleaning solution is added to the cleaning bath, the temperature is raised to 50°C, and the glass substrate is put in the cleaning solution, immersed for 30 minutes, and left to stand. Next, the cleaned glass panel was immersed in deionized water at 25°C for 3 minutes, and then the panel was taken out, and the same operation was repeated on it, and fi...
