What are the quality requirements of glass bottle manufacturers for glass products?

One,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.

Two,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.

Three,The appearance quality of the glass meets the technical requirements

Appearance quality The appearance quality of the original solar control coated glass sheet should meet the automotive-grade technical requirements. As the tempered and semi-tempered solar control coated original sheet for the curtain wall, 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

Six,Wear resistance of glass products

The wear resistance of the coated glass is tested according to the following wear resistance test, and the 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, and the difference between the average value of visible light transmittance before and after the test should not be greater than 4%. And the film layer can not have obvious changes.

Eight,Alkali resistance of glass products

The alkali resistance of the glass is tested according to the following acid resistance test, and 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 can not have obvious changes.
