Performance and application of glazed tempered glass

[China Glass Net] Color glazed tempered glass has been used as a decorative material for decades, and it has a history of nearly 20 years in China. Glazed tempered glass has become a mature glass processing product, and its use has been widely and widely used. Jinbo has launched glazed glass for many years. The more prominent feature of glazed glass is its decorative function, which is widely used in the architectural decoration industry to add luster to high-rise buildings and add color to the building. The use of glazed glass in other fields can also turn monotonous glass into a colorful world and beautify people's lives. The following will give explanations on different aspects of glaze, process, product characteristics, standards, applications, etc., so that the glazed glass product is better used by people.

The glaze glass industry uses inorganic glazes mainly for the production of architectural glazed glass, automotive glass, bottles and other decorative glass such as stove top stove glass, microwave oven shield, refrigerator electrical glass and so on. Glaze materials are divided into oxide glazes and precious metal glazes, among which inorganic non-metallic glazes are commonly used in architectural glazes. The glaze for building glaze is mostly screen printing or roller printing, so the glaze is also called ink. The ink has three major components: color, frit, and oil. The coloring materials are mostly metal oxides, which are covered on the surface of the glass after printing and sintering to form an opaque colored layer (the individual colored glazes are transparent or translucent), which exerts the coloring function of the colored glaze. The frit itself is a vitreous material that binds to the colorant after sintering and produces a unique luster. In addition, the frit has the function of adjusting the expansion coefficient of the glaze layer, so that the color glaze layers of different colors are matched with the thermal expansion coefficient of the glass substrate, thereby avoiding the phenomenon of cracking and falling off of the glaze layer. The oil agent is used to adjust the viscosity of the ink, making the ink suitable for different printing processes.

The process glaze glass is a glass product which is printed on the surface of the glass by screen printing (or a roller machine, etc.), and then dried and heat-treated to form a long-lasting glaze layer on the surface of the glass. The production process of glazed glass usually includes four main steps: production preparation, glazing, drying and heat treatment. Among them, the production preparation is very different due to different printing methods. In particular, the silk screen printing is more complicated and professional, and has formed a small industry circle, so it is skipped here. Glazing can be realized by screen printing, roller printing, etc., and even glazing can be performed by spraying or hand-painting. Drying is usually carried out continuously following the glazing. The purpose of drying is to gradually evaporate the oil and avoid direct heating to cause blasting. The thicker the glaze layer, the higher the coverage and the more obvious and necessary drying effect. The heat treatment includes different heat treatment methods such as tempering, semi-tempering and hot bending. The sintering temperature of the glazed glass is generally between 650 and 750 ° C. When the temperature is too high, the color becomes lighter. If the temperature is too low, the melting is not complete and the gloss is lacking.

Color glaze glass features colorful glaze glass with rich colors and patterns. Its color and pattern can be customized according to customer's requirements. It has a wide range of uses, stable color, anti-aging, acid and alkali resistance, no fading, and outstanding decorative effect. At the same time, it can absorb and reflect part of the solar heat energy, and the shading effect is obvious. Different heat treatments are available to obtain glass products with different functions. The glazed glass can be further processed by lamination, interlayering, hollowing, etc., adding more functions and effects. Not only flat glaze, but also curved glazed glass.
