example 1
[0016] 1) Mix 290g of tea seed powder with 199g of edible alkali and 95g of sodium phosphate to make a cleaning agent;
[0017] 2) Brew the mixture in step 1) with 4.5L of 80°C hot water, stir until completely dissolved, and then filter through a 120-mesh screen;
[0018] 3) Pour the filtered solution into an ultrasonic tank, adjust the ultrasonic frequency to 30kHz, and when the temperature of the solution is at 50°C, put 1,000 thermistors with a glass-sealed diode structure soaked in methyl silicone oil into it and start cleaning , wash for 5 minutes;
[0019] 4) After cleaning, rinse with tap water until the surface of the component is rinsed clean, and dry.
example 2
[0021] 1) Mix 300g of tea seed powder with 190g of edible alkali and 90g of sodium phosphate to make a cleaning agent;
