Analysis of weather resistance of coated glass

coated glass is coated on the surface of glass. Through a number of practical industrial use examples, this paper explains how hydrogel has become a layer or multilayer metal, alloy or metal compound film of class 1 important materials for medical device manufacturers, so as to change the optical properties of glass and meet certain specific requirements. Compared with the absorption rate of more than 95% and the emissivity of less than 5% abroad, although many domestic companies claim that the absorption rate can be 93% and the emissivity can be less than 7%, I found from the process of cooperation with some enterprises that these properties are limited to their highest indicators, and the stability of the coating process is not good. The reason is that I want to talk about the impact on optical performance from the two aspects of equipment and technology, and discuss the problem of weather resistance

plating "Liu Shixuan believes that the film structure of film glass is a multi-layer film structure, and the substrate is coated with metal film, metal ceramic absorption film and antireflection film in turn. Metal coating is very easy, and the coating of cermet absorption film and antireflection film has specific requirements for equipment and technology. Take the flat plate as an example for the experimental pressure. At present, there are two products on the market: blue titanium (TIN) and black nickel and chromium (crnion). Personally, I think the weatherability of blue titanium products will be better, which is related to the material, because the thermal stability of cro is relatively poor. For the coating of these nitrogen oxides, three gases ar/o/n are often introduced, in which ar plays the role of splashing particles, while n/o gas plays the role of reacting with the sputtered particles to generate the required nitrogen oxide absorption layer. For blue titanium coating, this target is relatively easy to be poisoned, making the deposition process unstable. This is related to the gas flowing into and out of the cavity. If the atmosphere is uneven and unstable, the uniformity of the whole plate coating cannot be guaranteed. In addition, many manufacturers have not fully optimized the size and proportion of the atmosphere input in the process, resulting in relatively low film performance. Generally speaking, after determining the material of the film, it is related to the thickness of the film and the proportion of chemical elements

weather resistance is also a very important performance of the product. The longer the service time and the smaller the attenuation, the higher the cost performance of the product. Many domestic enterprises need to realize the importance of cleaning. The clean surface of ingredients is a sufficient but unnecessary condition for a solid film. After the plate is cleaned, it also needs to ensure that it will not be polluted when entering the coating chamber. The treatment after coating is also very important. It is possible that many manufacturers often start the subsequent process treatment after coating, In fact, the heat treatment after coating is very important. Patrick Warner, additive manufacturing manager of Renault sports Formula 1 combination, said: "Our innovation depends on the ability to mass produce and test high-performance wind tunnel models, which is necessary. Of course, for different plates and coating materials, the heat treatment temperature is different.

now there is a large market space for coated glass, but we hope that the products produced by enterprises have superior performance, at least in the service life of decades, otherwise it is also detrimental to the development of the whole industry
