Embodiment 1
[0024](1) a new type of cleaning powder, including the following components by weight: 48% inorganic base, 22% sodium hydroxyethyl phosphonate, 5% sodium citrate, 22% sodium gluconate, 1% sodium formate, 1% sodium nitrogen triaceate, 1% sodium fluoride.
[0025](2) Preparation method:
[0026]S1, first pulverizing the inorganic base by a pulverizer to 100 mesh powder;
[0027]S2, by stirring under stirring conditions, sequencing corrosion inhibitor, inorganic base, buffer, chelating agent, and stirred for 30 minutes to uniform.
[0028](3) How to use: First add new cleaning powder to water to 3% mass concentration, ultrasound cleaning at 60 ° C.

Embodiment 2-3
[0032]Example 2-3 Novel Cleaning Powder and Comparative Example 1-4 The preparation method of cleaning powder is the same as in Example 1.
[0033]First, performance test
[0034]For Examples 1-3 clean flour, comparison 1-4 cleaning powder for performance test, specific:
[0035]1. First add the cleaning powder to water to 3% mass concentration.
[0036]2. Ultrasound washed 2 min under the condition of 60 ° C. After cleaning, drying, the drying sample glass is determined by performing performance, and the details of the measurement results are shown in Table 2.
[0037]Table 2
[0038]
[0039]From the above, it is known that the application for optical glass cleaning powder relative to the existing electronic glass cleaning agent, after cleaning, the product scratches are significantly reduced by 1-6%, and the yield is increased by about 10-43%, and the droplet angle is reduced by 40-50. %about. The smaller the average of the water droplet, the higher the clean degree, the smoother the glass surface.
