Hunan decorative inkViscosity and drying properties are particularly sensitive to changes in environmental temperature. As the temperature rises, viscosity decreases, and drying speed increases; conversely, viscosity increases and drying speed slows down. Now, let's understand how to store Hunan decorative ink.
Environmental humidity also affects the drying properties of the ink. Generally, the temperature in printing workshops is controlled between 18~25 degrees Celsius, and humidity is controlled between 55%~65%.
Hunan decorative ink also has a certain shelf life. If stored for too long, various components in the formula may loosen or precipitate. Therefore, it is not suitable for long-term storage, and a storage period of about 1 year is advisable. Otherwise, it may affect printing quality or cause printing defects.
1. How to extend the shelf life of Hunan decorative ink:
1. The remaining ink after use should be sealed and stored in a cool, dry place for future reuse. Before using again, it must be filtered with a filter of over 100 mesh, and mixed with new ink after thorough stirring.
2. In some northern regions, the winter climate is harsh, and ink should be stored outdoors to prevent low-temperature gelation. If the ink has gelled, it can be moved to a warmer warehouse or placed in hot water to restore the insoluble substances.
3. The storage and management of Hunan decorative ink should follow the "first in, first out" principle. That is, use the ink purchased earlier first to avoid the ink being stored for too long and affecting its use.
4. Seal to prevent dust. A large number of garbage particles and various impurities falling into the ink tank and adhering to the appearance of the label material can significantly affect print quality.
5. Safety should be a priority. When storing ink, it should be kept as far away from fire sources and heat sources as possible to prevent accidents.
6. The ink warehouse should maintain a constant temperature, and the temperature difference with the printing plant should not be too large. If there is a significant temperature difference, pour the ink into the printing plant in advance, which is beneficial for stabilizing performance and ensuring production efficiency.
2. Regarding the management of remaining Hunan decorative ink
1. The solvent used in Hunan decorative ink is a low-boiling solvent, so the volatilization during printing can lead to an unbalanced mixing ratio of the solvent, or the temperature drop during solvent volatilization can cause the surface of the ink and the surface of the roller to cool, allowing moisture in the air to penetrate into the ink.
2. During the printing process, due to reasons such as film fragments and dust attracted by static electricity mixing into the ink, especially when the pattern area is small and the amount of ink used is low, the remaining ink is prone to changes. The remaining ink has low viscosity, and separation and precipitation often occur early. Therefore, it must be thoroughly stirred before reuse or filtered with a wire mesh of over 1000 mesh and mixed with new ink for digestion.
