The interior and exterior glass market is undergoing major changes centering on various designs. Although interior glass currently occupies about 35% of the total glass market in terms of volume, interior glass has been released in various designs recently, but more than 80% of the glass is supplied to general glass through chamfering. Occupies. Most of the color glass and design products that are often referred to as interior glass are around 15-20% of the total interior glass volume.
The glass ink has no limit of expression, and it is excellent in directing the space by designing the desire to decorate the space with the transparency of the glass. The integration of the interior concept in the living space goes beyond simply decorating the living space, and the interior is grafted to everything that is commonly encountered, such as bathrooms, furniture, and electronics, creating a visual beauty of the living space.
As a result, the use of glass is increasing greatly, and the use thereof can be considered infinite. Currently, the share of interior in the overall glass market is narrow compared to the growth potential, but it is a high potential market that can be gradually increased through the development of new products.
In the architectural market, various patterns such as lattice, flowers, and animals are produced by etching for translucent treatments for privacy and aesthetic reasons on the glass inside and outside of houses and buildings. Current etching process methods are time consuming and environmental problems due to high cost and difficulty of operation.
In the electronics market, most home appliances (air conditioners, refrigerators, dishwashers, etc.) in Korea have been vitrified and printed on the back of glass to maximize the visual effect. However, the application of glass realizes the high quality of the product, but the high glossiness causes the consumer to get tired quickly, and there are limitations in implementing the three-dimensional effect. In addition, the ink currently being applied for the front surface is a ceramic type, which requires heat-reinforced working conditions of 600 ° C or higher after printing, and it is difficult to realize simple colors and various effects.
