Water-based ink printing aluminum foil fading reasons
- 2024-08-02 17:23:10
- admin
Aluminum foil can also be printed with water-based ink. As a non-absorbent substrate, aluminum foil poses a major challenge to water-based ink printing. However, some aluminum foil products that require food-grade printing cannot be printed with oil-based inks, so water-based inks have become the best choice. However, due to the poor absorption of aluminum foil to water-based ink, many inexperienc...

Analysis of water based emulsion breaking phenomenon
- 2024-09-13 13:23:06
- admin
There are several main reasons for water-based emulsion breaking: 1.Large temperature changes, water-based emulsion is easy to separate into water phase and oil phase at high temperature, and easy to crystallize at low temperature. 2.The selection of emulsifier is improper, and the type and dosage of emulsifier are different, which has a great impact on the stability of emulsification. The choice ...

Textile coating process detailed explanation
- 2024-08-23 17:32:42
- admin
Before the textile coating, it is necessary to pretreat the textile surface to ensure the adhesion and quality of the coating. Common surface treatment methods are: cleaning, degreasing, polishing and so on. Cleaning can be done with hot water or solvents, degreasing can be done with alkaline or acid degreasing agents, and polishing is done by mechanical removal of surface hair. The choice of coat...
