Description

technical field [0001] The invention relates to the technical field of glass online coating, in particular to a preparation process of light blue low-reflection sunlight control coated glass. Background technique [0002] With the increasing use of solar control coated glass, solar control coated glass is used in large-scale curtain wall buildings. However, since solar control coatings are all heat-reflective coated glasses, their visible light reflection is generally relatively high. The commonly used solar control coated glass is made of Ti, Cr and other metals and metal oxides on the glass surface. The on-line production is basically a silicon film. All of these often cause "light pollution" due to their reflection effects. Light pollution is followed by exhaust gas, A new source of environmental pollution after waste water, waste residue and noise pollution, mainly including white light pollution, artificial daytime pollution and color light pollution. The existence of ...
