[China Glass Net] First of all, the good quality dimming glass has excellent light transmittance when it is energized, clear and transparent, and has a beautiful appearance. When it is powered off, it is transparent and opaque, which can protect privacy. The simple test method is to put the palm of your hand on the back of the glass. When the power is off, look at the palm of the back from the front. Although the blurred shadow is visible, you should not see the fingerprint of the palm. Or an object can be placed 10 cm away from the front glass. When the two sides of the light are balanced and not one side of the backlight, one side of the strong light, the object should not be seen from the reverse side. The light transmittance of a generally good dimming glass should be above 70%.
Secondly, consumers can choose to use the corresponding glass panels according to the application requirements of the glass. For example, tempered glass should be used as a dimming glass panel for public buildings and bathrooms with high safety factor requirements, and for outdoor curtain wall applications. For customers with high fire protection requirements, fire-resistant glass can be used as a panel, which should be used in places where bending is required. Bend glass to make panels, etc.
Later, the technical strength can be judged according to the glass width provided by the manufacturer. The production of dimming glass film is a technically high and difficult process. The larger the size, the harder it is to produce. Therefore, many domestic manufacturers need to block the splicing of some orders whose width exceeds the larger size of their dimming film. As is well known, for dimming glass, if a plurality of pieces of glass having a narrow width are spliced, it is visually ugly, and it is easy to affect visual aesthetics and practicality. Therefore, the production capacity of wide-format products can reflect the technical content and quality standards of the products to a certain extent.
