Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0027] Such as figure 1 As shown, the detection method of the car wash cleanliness of the present embodiment comprises the following steps:
[0028] 1. Select a piece of clean transparent material as the substrate, and the light transmittance of the transparent material is P0;
[0029] 2. Coating the test solution on the surface of the substrate and drying it to make a sample with a standard coating;
[0030] 3. Measure the light transmittance P1 of the sample and make a record;
[0031] 4. Use the water jet to record the water pressure, flow velocity, flow rate, angle, water quality and working time to wash the sample to remove the coating on the surface of the substrate;
[0032] 5. Dry the sample;
[0033] 6. Measure the light transmittance P2 of the sample after drying, and make a record;
[0034] 7. Analyze the dirt removal effect by...
