Powder Surface Modification Technology: How to Significantly Enhance Product Value-Added?

Powder surface modification technology is an important means of increasing product value-added. By physical or chemical methods, it can change the physical and chemical properties of powder surfaces, such as surface energy, wettability, dispersibility, etc. For example, after surface modification of calcium carbonate powder, its hygroscopicity and oil absorption are reduced, particle size becomes smaller, it is easier to disperse in organic media, and the thermal stability temperature can also be sign

ificantly improved. In addition, modification technology can enhance the compatibility of powders with downstream products and improve the comprehensive performance of materials.

As a result, powders can be upgraded from general fillers to functional fillers, and their prices can also be significantly increased. Taking heavy calcium powder as an example, after coupling agent modification, its price can jump from 200-600 yuan per ton to 800-1200 yuan per ton, and the price of high-quality modified powder is even as high as 1800-2200 yuan per ton.
