Advantages:
1. High dispersibility and permeability: Small-particle silica sol has a small particle size and can be more evenly dispersed in the ink. At the same time, it has good permeability and can fully penetrate into the paper fiber, enhancing the adhesion and durability of the printed product.
2. Improve printing accuracy: Due to its small particle size, small-particle silica sol can provide better detail performance and pattern clarity during the printing process, and is suitable for high-precision printing tasks.
3. Enhance ink performance: Small-particle silica sol can be used as an additive to ink to improve the dispersibility, stability and printing performance of the ink.
Disadvantages:
1. Relatively high cost: The preparation process of small-particle silica sol is relatively complex, and the requirements for raw materials, equipment and environment are high, so the cost may be higher.
2. Special treatment may be required: In some cases, special pretreatment or the addition of other additives may be required to ensure the stability and dispersibility of small-particle silica sol in ink.
