Usage
W&Q magnesium sulfate monohydrate is widely applied in multiple fields, with dedicated specifications for each industry to ensure optimal application effects.
In agriculture, it serves as a high-efficiency magnesium fertilizer, which is an essential nutrient for plant chlorophyll synthesis. It can supplement magnesium deficiency in soil, promote crop photosynthesis, enhance stress resistance (drought, disease), and further improve crop yield and quality, suitable for grain, fruits, vegetables, and cash crops.
In industry, it is used in water treatment (as a flocculant to remove impurities and heavy metals), textile dyeing (as a mordant to improve color fastness), and chemical synthesis (as a catalyst or raw material for producing other magnesium compounds). It is also applied in building materials to enhance product hardness and durability.
In healthcare and food industries, the food-grade and pharmaceutical-grade products of W&Q are utilized as nutritional supplements to provide magnesium, which is crucial for human and animal nerve conduction, muscle contraction, and bone health. They are also used in food processing as stabilizers and regulators to improve product quality and shelf life.
