1. Glass size deviation of non-tempered glass
The allowable deviation of the size, thickness, curvature, and diagonal deviation of non-tempered solar control coated glass should meet the requirements.
2. The size deviation range of tempered glass glass products
The allowable deviation of the size, thickness, curvature, and diagonal deviation of tempered solar control coated glass and semi-tempered solar control coated glass should 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 and semi-tempered original solar control coated glass for curtain walls, the edges should be finely polished.
Fourth, the optical properties of glass products
Ultraviolet transmittance, visible light reflectance, direct sunlight transmittance, direct sunlight reflectance and total solar transmittance.
Five, color uniformity
The color uniformity of the solar control coated glass is expressed by the color difference of the CIELAB uniform color space, and the unit is CIELAB. The excellent product of the reflected color of the solar control coated glass
6. Wear resistance of glass products
The wear resistance of the coated glass is tested according to the following wear resistance test. The maximum difference between the average value of the visible light transmittance before and after the test should not be greater than 4%.
Seven, the acid resistance of glass products
The acid resistance of the glass is tested according to the following acid resistance test. The maximum 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 can not have obvious changes.
8. Alkali resistance of glass products
The alkali resistance of the glass is tested according to the following acid resistance test. The maximum 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 can not have obvious changes.
