1. Glass size deviation of non-tempered glass
Non-tempered sunlight control coated glass size tolerance, thickness tolerance, curvature, diagonal difference should meet the regulations.
Non-tempered sunlight control coated glass size tolerance, thickness tolerance, curvature, diagonal difference should meet the regulations.
2. Dimensional deviation range of tempered glass products
The size tolerance, thickness tolerance, bending degree and diagonal difference of tempered sunlight control coated glass and semi-tempered sunlight control coated glass shall meet the requirements.
3. The appearance quality of the glass meets the technical requirements
Appearance quality The appearance quality of the original solar control coated glass should meet the automotive-grade technical requirements. As the toughened curtain wall, the semi-tempered original solar control coating should be edge-finished.
4. Optical properties of glass products
Ultraviolet transmittance, visible light reflectance, direct sunlight transmittance, direct sunlight reflectance and total solar transmittance.
5. Color uniformity
The color uniformity of sunlight control coated glass is expressed by the color difference of CIELAB uniform color space, the unit is CIELAB. The reflection color color difference of sunlight control coated glass is excellent
6. Wear resistance of glass products
The abrasion resistance of the coated glass shall be tested according to the abrasion resistance test described below. The difference between the average value of the visible light transmittance before and after the test shall not exceed 4%.
7. Acid resistance of glass products
The acid resistance of the glass is tested according to the following acid resistance measurement. The difference between the average value of the visible light transmittance before and after the test should not be greater than 4%. And the film layer must not have obvious changes.
8. Alkali resistance of glass products
The alkali resistance of the glass is tested according to the following acid resistance measurement. The difference between the average value of the visible light transmittance before and after the test should not be greater than 4%. And the film layer must not have obvious changes.
