Discussion on post-press drying process of high temperature glass ink for automobile
In automotive glass screen printing, high-temperature glass ink is mainly used. Before the glass is tempered or thermally bent, the ink printed on the glass surface must be dried, and the drying process of these ink layers has an impact on screen printing. Quality and speed play a crucial role.

The composition of high-temperature glass ink is mainly composed of three substances: pigment, flux of low-melting glass powder and toner. Among them, the pigment is a high-temperature decomposition product, and the firing temperature of at least 600 ° C must be guaranteed. Pigment is the main material for color rendering. The pigment composition of the most commonly used black tempered ink is iridium oxide or mixed cobalt chromate and manganese salt. The color composition of the white high-temperature glass ink is tin oxide, bone powder, zirconia or high manganese soil. The toner is composed of terpineol, turpentine and an appropriate amount of alkyd resin.
Therefore, the drying method of high-temperature glass ink is mainly based on volatilization drying, so that heating-type drying equipment should be selected for the drying device after printing. The correct choice of drying heating method can improve drying efficiency and quality on the one hand, and can save energy on the other hand. Improve the economic benefits of products.
