Molecular Barrier Protection: Advanced Powder Surface Modification and Anti-Caking System Engineering
In the global trade of granular NPK, nitrate-based, and water-soluble fertilizers, maintaining free-flowing physical stability during extended transit through humid tropical regions is a primary commercial challenge. Highly hygroscopic compounds naturally absorb atmospheric moisture, triggering salt dissolution and recrystallization that cements loose granules into solid, unmarketable blocks. Traditional anti-caking practices—such as basic oil spraying or…
