The use of ceramic ink for touch screen cover has some special advantages and characteristics, which make ceramic ink an important material in the production of touch screen cover. The following is a detailed analysis of its special features:
1, high temperature stability
High-temperature resistance: ceramic ink can remain stable in high-temperature environments above 300 degrees, while the touch screen cover plate may encounter a variety of high-temperature environments in the course of use, such as direct sunlight, high-temperature working environment. The high temperature resistance of ceramic ink ensures that the touch screen cover can still maintain stable performance in these environments.
High bonding strength between ink and glass: after high-temperature baking and physical strengthening, the bonding strength between ceramic ink and glass is very high and not easy to fall off or discoloration, which ensures the long-term stability and durability of the touch screen cover.
2. Weathering and corrosion resistance
High weather resistance: under long-term use, ceramic ink is not easy to appear discoloration, loss of light, cracking, peeling and other problems, which makes the touch screen cover plate in the outdoor or harsh environments can still maintain excellent performance.
Chemical resistance: ceramic ink can resist the erosion of chemical substances, not easy to be corroded by acid and alkali, has the characteristics of water resistance, acid and alkali resistance, detergent resistance, solvent resistance, salt spray resistance, etc., which ensures the stability of the touch screen cover plate in a variety of environments.
Wide range of applications
Diversified application scenarios: Since ceramic ink has the above multiple advantages, the touch screen cover printed with ceramic ink can be applied to various scenarios, such as park scenic spots (outdoor display), aviation, ships (seaside, offshore), special vehicles, highways, industrial embedded, agricultural machines, charging piles, self-service kiosks, express cabinets, bus stops, and so on.
Production process of ceramic ink glass cover plate: The glass cover plate produced with ceramic ink is slightly different from the glass cover plate process produced with conventional low-temperature ink.
The production process of glass cover produced by conventional ordinary ink is: cutting - CNC engraving - grinding - chemical tempering - screen printing - coating - cleaning - packaging.
The production process of glass cover plate with ceramic ink is: cutting - CNC engraving - grinding - screen printing - physical tempering - coating - cleaning - packaging.
The main process difference between them is the order of screen printing and tempering and the way of tempering. The ceramic ink is printed on the glass, which is fused with the glass after instantaneous baking at a high temperature of 680-720℃ and instantaneous cooling for physical reinforcement, realizing a very strong adhesion and durability of the color on the glass, which can withstand years of sunlight and have a certain degree of resistance to atmospheric corrosion.
