Do you know how to choose a dimming glass?
[China Glass Network] 1. See the manufacturer At present, most of the domestic dimming glass processing manufacturers have a processing history of no more than 3 years, and there are few engineering cases. The quality and reputation are waiting to be verified by time. More care should be taken when purchasing. Buy a well-known brand on the market or a dimming glass product produced by a well-known manufacturer, you can choose a regular professional glass manufacturer. Instead of dimming glass sales agents or intermediaries such as trading companies, you can avoid potential risks and enjoy good quality and after-sales service. 2, see technical parameters Good quality dimming glass has excellent light transmission when it is energized, clear and transparent, beautiful appearance and transparent and opaque when power is off, which can protect privacy very well. Simple test method: 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 you can see the blurred back, you must not see the fingerprint of the palm. Or an object can be placed at a distance of 3cm from the front glass. When the two sides of the light are balanced and not one side is backlit, and one side is strong, the object should not be seen from the reverse side. The light transmittance of a good quality dimming glass should be around 75%. 3, dimming film quality The quality of the dimming film is one of the more important factors determining the quality of the finished dimming glass. Therefore, the quality of the dimming film of the dimming glass manufacturer should be discerned when purchasing the dimming glass. 4, see the project case For the purchase of dimmable glass products with stable performance and guaranteed after-sales service, it is more important to look at the relevant application engineering cases of the manufacturers. When we choose a manufacturer, we must not only look at the actual engineering case of the manufacturer, but also carefully check the actual photo of the actual installation site of the manufacturer's dimming glass, instead of the effect picture of the PS after the computer. Therefore, before purchasing dimming glass, you can ask the manufacturer to provide several well-known works and real photos for reference. 5, see production equipment The production of dimming glass by autoclave generally uses PVB film. The main advantage is high transparency and high bonding strength, but the temperature of PVB must be 135 degrees to meet the requirements of transparency and bonding strength, while the aging temperature of liquid crystal film is only 120. degree. Therefore, the edge shrinkage of the dimming glass made by the autoclave is generally 6-10 mm, such a wide bright side, when the partition requiring the seam is required, a transparent zone of 10-20 mm is formed between the two glasses, and is not electrically controlled. The seam stitching effect at the glass splicing is very poor. At the same time, the shrinkage rate of PVB film in the autoclave production process is a major drawback that causes a significant reduction in the performance and life of the dimming glass. In order to improve production efficiency, some domestic manufacturers use high-temperature autoclave to produce, so that the whole of the dimming glass products will appear yellow in the process of use, the transparent and opaque liquid crystal film can not be converted normally, and the liquid crystal film gradually shrinks. Therefore, it is recommended to use a high-temperature and high-pressure one-step vacuum forming method to obtain a dimming glass, which has the advantages of relatively stable product performance and long service life.
