According to foreign reports, mainly due to the Japanese earthquake and tsunami on March 11th, the amount of imported caustic soda in the United States in April fell by 28% to 132,643 tons, a year-on-year drop of 10%. Goods imported from Japan decreased by 39% to 8,999 tons. In the first week of March, the price of caustic soda in Asia was approximately US$375/dmt (CFR South East Asia), while in the first week of April, the price rose to US$485/dmt (CFR South East Asia). Rising prices in Asia have led to dependence on imported West Coast buyers from the United States to start looking for supplies from the United States Gulf of Mexico. In addition, the amount of caustic soda that China and Taiwan exported to the United States decreased by 56% and 33% respectively. Silica Matting Agent In Canvas Paint, Canvas Material Silica Dioxide,Canvas Material 7631-86-9,Eco Solvent Agent Silica Guangzhou Quanxu Technology Co Ltd , https://www.silicamattingagent.comSilica-based matting agents are often used in the production of eco-friendly solvent-based canvas materials to give the finished product a non-glossy, or "matte" finish. These agents work by scattering light in multiple directions, which reduces the glare and enhances the visual texture of the fabric.
In the context of eco-solvent printing on canvas, silica matting agents can help reduce environmental impact while still providing high-quality print results. They typically have the following properties:
1. **Non-toxicity**: Silica-based products are generally considered safe for both the environment and human health, making them a good choice for eco-conscious applications.
2. **Low VOCs**: Eco-solvent inks already emit fewer volatile organic compounds (VOCs) compared to traditional solvent inks. Incorporating a silica Matting Agent can further reduce VOC emissions without compromising the quality of the printed image.
3. **Energy Efficiency**: Using a silica matting agent can potentially improve the efficiency of the printing process. By reducing the glossiness of the ink, it may require less energy to dry, especially when compared to highly glossy inks.
4. **Durability**: Silica matting agents can also contribute to the longevity of the printed canvas by enhancing its resistance to fading and wear.
Some common types of silica matting agents include:
- **Nano-silica**: These fine particles can be incorporated into the ink formulation to provide a subtle matte effect without significantly altering the color appearance.
- **Coated silica**: This type of silica is treated with a surface coating to improve compatibility with the ink and enhance the matting effect.
- **Hybrid silica**: These materials combine the benefits of different silica types to achieve a specific finish, such as improved light scattering for better texture or enhanced durability.
When selecting a silica matting agent for an eco-solvent canvas application, it's important to consider factors like the specific requirements of the printing process, the desired aesthetic outcome, and the overall environmental impact of the product. Consulting with material suppliers and testing under real-world conditions can help ensure the best results.
