Brief description of the advantages and disadvantages of high temperature glass ink.
The price of high-temperature glass inks on the market varies, and the quality varies. Low-quality inks are mainly manifested in rough processing, or even no grinding process, and the particle fineness of the ink cannot reach the conventional 10-15m standard. In addition to the poor screen printing effect, the ink expansion coefficient cannot be controlled, which affects the impact resistance of the finished tempered glass, and is also an important factor in the bursting of the glass during the tempering process.

High temperature glass ink, also known as high temperature ink, tempered glass ink. Used in glass tempering and hot bending processes. What are the advantages and disadvantages of high temperature glass ink compared with ordinary glass ink?
The disadvantages of high temperature glass ink are:
1. The color of the ink will change after high temperature sintering, which has high requirements for color matching technology.
2. It needs to be equipped with large-scale equipment such as tempering furnace. The processing process consumes a lot of energy, the process is complex, and the application range is not as wide as that of low-temperature ink.
3. The color of high temperature ink is not as rich as that of low temperature ink, and the color is generally not as good as that of low temperature ink.
The advantages of high temperature glass ink are:
Glass is a non-adsorptive substrate with a smooth surface. In the glass screen printing process, low-temperature baking inks generally have problems such as insufficient adhesion, weak weather resistance, unstable performance, and are prone to paint loss and discoloration after processing.
High temperature glass ink is mainly composed of high temperature flux (glass powder) and pigment. After high temperature sintering at 500 to 720 ° C, it is melted and bonded to the glass surface. It is far from ultra-low temperature ink in terms of adhesion and weather resistance.
