2. The size deviation range of the glass tea pot of tempered glass, the allowable deviation of the size of the tempered sunlight control coated glass and the semi-toughened sunlight control coated glass, the allowable deviation of the thickness, the curvature, and the diagonal difference should meet the regulations.
3. The appearance quality of the glass meets the technical requirements, and the appearance quality of the original solar control coated glass sheet should meet the automotive-grade technical requirements. As the tempering and semi-tempered solar control coated original sheet for the curtain wall, the edge finishing is required.
4. Optical properties of glass tea pot, ultraviolet transmittance, visible light reflectance, direct sunlight transmittance, direct sunlight reflectance and total sunlight transmittance.
5. Color uniformity, the color uniformity of sunlight-controlled coated glass is expressed by the color difference of CIELAB uniform color space, and the unit is CIELAB. The reflected color difference of sunlight-controlled coated glass is excellent
6. The abrasion resistance of glass tea pot and the abrasion resistance of coated glass shall be tested according to the following abrasion resistance test. The difference between the average value of visible light transmittance before and after the test shall not be greater than 4%.
7. The acid resistance of glass tea pot, the acid resistance of glass shall be tested according to the following acid resistance measurement, and the difference between the average value of visible light transmittance before and after the test shall not be greater than 4%. And the film layer can not have obvious changes.
8. The alkali resistance of glass tea pot, the alkali resistance of glass shall be tested according to the following acid resistance measurement, and the difference between the average value of visible light transmittance before and after the test shall not be greater than 4%. And the film layer can not have obvious changes.
