There are two kinds of blue star online LOW-E coated glass. One is pure low-E coated glass, which not only maintains the high visible light transmittance of colorless transparent glass, but also has excellent low radiation function. Second, the colored low-emissivity coated glass has good light transmittance and shading performance, and excellent low-emissivity function. Heat insulation, sun shading and low radiation are all good manifestations of the energy-saving concept, and various combinations of products bearing the energy-saving concept provide the possibility for the processing and selection of insulating glass, which is a good foundation for realizing the building energy-saving standard.
Product features: high efficiency, energy saving and environmental protection: good thermal insulation performance, and it is an ideal energy saving and environmental protection material.
Good lighting: high visible light transmittance and good lighting effect. Stable chemical properties: it can be used on a single chip and preserved for a long time, giving full play to the advantages of deep processing enterprises.
Stable hot working performance: it can be used for deep processing such as tempering, hot bending and interlayer at will.
Stable mechanical properties: firm film layer, good wear resistance and not easy to scratch. It is not necessary to remove the edge film in the hollow machining process. Adopt online continuous production technology, with large scale and high production efficiency. Variety, can produce many colors. Coated glass is also called reflective glass. Coated glass is to coat one or more layers of metal, alloy or metal compound films on the surface of glass to change the optical properties of glass and meet certain requirements.
According to the different product characteristics, coated glass can be divided into the following categories: heat reflective glass, Low-E glass, conductive film glass and so on. Generally, heat reflective glass is coated with one or more thin films made of metals such as chromium, titanium or stainless steel or their compounds, so that the product is rich in color, with appropriate transmittance for visible light, high reflectivity for infrared light and high absorption rate for ultraviolet light. Therefore, it is also called sunlight control glass, which is mainly used in buildings and glass curtain walls. Low-emissivity glass is a kind of thin film system composed of multilayer metals such as silver, copper or tin or their compounds plated on the glass surface. The product has high transmittance of visible light, high reflectivity of infrared light and good heat insulation performance. Mainly used in buildings, cars, ships and other means of transportation. Due to the poor strength of the film, it is generally made of insulating glass. Conductive film glass is a conductive film such as indium tin oxide coated on the glass surface, which can be used for heating, defrosting, defogging, liquid crystal display and so on. There are many production methods of coated glass, mainly including vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition and sol-gel method. Magnetron sputtering coated glass can be designed and manufactured by magnetron sputtering technology, and can be plated with various colors on white glass substrates. The film has good corrosion resistance and wear resistance, and it is one of the most widely produced and used products at present. There is a certain gap between the varieties and quality of vacuum evaporation coated glass and magnetron sputtering coated glass, which has been gradually replaced by vacuum sputtering. Chemical vapor deposition (CVD) method is to introduce the reaction gas into the float glass production line, decompose on the hot glass surface, and uniformly deposit on the glass surface to form coated glass. This method has the characteristics of less equipment investment, easy adjustment, low product cost, good chemical stability and hot processing, and is one of the most promising production methods at present. The production of coated glass by sol-gel method is simple and stable, but its disadvantages are high light transmittance and poor decoration. Heat reflective glass and low emissivity glass are widely used for coating glass. Basically, vacuum magnetron sputtering and chemical vapor deposition are used.
