Glass cover new scheme: still do not make ceramic ink + physical strengthening and trouble
Ceramic ink after 680° high temperature instant baking and instant cooling of the physical strengthening, and glass melting as one, to achieve the color on the glass is very strong adhesion and durability, can withstand years of sunlight, corrosion of the atmosphere has a certain resistance, is the first choice for outdoor display glass cover plate processing.
Ceramic ink is also called high - temperature ink, is the need to be processed with physical strengthening. There are some relative problems.
1, physical strengthening is not in a dust-free environment, the processing process is easy to have miscellaneous points, foreign bodies and other poor quality, for the appearance of strict quality requirements of electronic display, good yield is not high, the cost is relatively high.
2, physical strengthening needs more than 3mm glass can be processed (glass is too thin, easy to break after high temperature), and there are requirements on size (products below 5 inches are not enough to strengthen the gap between the furnace roller, the glass will fall).
3, glass with ceramic ink only black and white, other colors will use low temperature ink.
In this way, for small size, thin, the need for multi-color printing of the glass cover plate and how to meet the outdoor sunlight does not fall off, does not change the condition.
