First, the glass size deviation of non-tempered glass
Non-tempered sunlight control coated glass size allowable deviation, thickness allowable deviation, curvature, diagonal difference should be in accordance with the provisions.
Second, the range of size deviation of glass products of tempered glass
Toughened sunlight control coated glass and semi-toughened sunlight control coated glass size allowable deviation, thickness allowable deviation, curvature, diagonal difference should be in line with the provisions.
Third, the appearance quality of glass meets the technical requirements
Appearance quality of the original sunlight control coated glass should be in line with the appearance of automotive-grade technical requirements, as a curtain wall with toughened, semi-tempered sunlight control coated glass should be edge of the original edge of the fine grinding treatment.
Optical properties of glass products
Ultraviolet transmission ratio, visible light reflection ratio, direct sunlight transmission ratio, direct sunlight reflection ratio and total sunlight transmission ratio.
V. Color uniformity
The color uniformity of sunlight control coated glass is expressed by the color difference of CIELAB uniform color space, unit CIELAB.The reflected color difference of sunlight control coated glass is superior.
Abrasion resistance of glass products
The abrasion resistance of the coated glass is tested according to the following abrasion resistance test, and the difference in the average value of visible light transmission ratio before and after the test ****** should not be more than 4%.
Acid resistance of glass products
The acid resistance of the glass shall be tested according to the following acid resistance test, and the difference of the average value of the visible light transmittance ratio before and after the test shall not be more than 4% of the average value of the visible light transmittance ratio of ******. And the film layer should not have obvious changes.
Eight, the alkali resistance of glass products
Alkali resistance of glass according to the following acid resistance test, before and after the test, the difference between the average value of visible light transmission ratio of ****** should not be greater than 4%. And the film layer should not have obvious changes.
