Product Description
Coated glassCan be divided into heat reflective glass, low radiation and conductive glass, etc., mainly used in wall decoration, windows, special optical requirements of equipment or instruments and other fields.
- All kinds of color film, rich in color.
- The reflection film improves the light transmittance of the glass.
- The heat reflecting film reflects infrared rays and absorbs ultraviolet rays.
- Heating film, improve the glass heating performance, with defrosting and defogging effect.
Products are rich, can more effectively meet the needs of professional users in the industry, is a precision glass deep processing experts, including five series of products are as follows:
1. flat, hot bending, bending steel tempered glass series;
2. special glass such as: quartz glass tubular, flake, special-shaped processing and special quartz glass bead series; high borosilicate glass tubular, flake, special-shaped blown glass product series; induction cooker, electric ceramic stove, fireplace, heater with microcrystalline glass series;
3. optical glass cold processing, coated optical glass series; Security cameras, projectors with optical lenses and LOGO lenses and military gun pointing device, glued mirror military series products; Watches, audio with single-piece, double-piece tempered glass series;
4. appliances, smart home panel, lighting, lock card security tempered glass series;
5. diving goggles with flat, myopia lenses, hyperopia lenses, double-focus hyperopia lenses series;
6. processing: water cutting, carving, special-shaped edge grinding, car edge, polishing, sandblasting, silk screen printing, bending steel, film, etc:
7. private customization, to meet customer personalized products.
The above glass series products are widely used in lighting, smart home, smart wear, 5G, 3D printing, electronic scales, home appliances, security products, optical lenses, projectors, UV machines, windows, boilers, flashlights, watches, diving mirrors and other industries.
Coated glass is also called reflective glass. Coated glass is coated with one or more layers of metal, alloy or metal compound films on the glass surface to change the optical properties of the glass to meet certain specific requirements. According to the different characteristics of the product, the coated glass can be divided into the following categories: heat reflective glass, low-e glass (Low-E), conductive film glass, etc.
Heat reflective glass is generally coated with one or more layers on the surface of the glass, such as chromium, titanium or stainless steel and other metal or its compound composition of the film, so that the product is rich in color, for visible light has the appropriate transmittance, the infrared has a high reflectivity, the ultraviolet has a high absorption rate, therefore, also known as solar control glass, mainly used in construction and glass curtain wall; low-emissivity glass is a thin film system composed of multiple layers of metals such as silver, copper or tin or their compounds plated on the surface of the glass. The product has high transmittance to visible light, high reflectivity to infrared rays, and good thermal insulation. It is mainly used in buildings, automobiles, ships and other vehicles. Due to the poor film strength, it is generally made into hollow glass for conductive film. Glass is coated with conductive films such as indium tin oxide on the surface of glass, can be used for glass heating, defrosting, defogging and used as a liquid crystal display, etc.
There are many production methods of coated glass, including vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition and sol-gel. Magnetron sputtering coating glass using magnetron sputtering technology can be designed and manufactured multi-layer complex film system, can be plated on the white glass substrate a variety of colors, the film layer of corrosion resistance and wear resistance is better, is the production and use of the most one of the products. There is a certain gap between the variety and quality of vacuum evaporation coated glass and magnetron sputtering coated glass, which has been gradually replaced by vacuum sputtering. Chemical vapor deposition method is in the float glass production line into the reaction gas on the hot glass surface decomposition, evenly deposited on the glass surface to form coated glass. This method is characterized by less equipment investment, easy control, low product cost, good chemical stability, can be hot processing, is one of the most promising production methods. The sol-gel method produces coated glass with simple process and good stability, but the disadvantage is that the light transmittance ratio of the product is too high and the decoration is poor.
