When it comes to magnesium sulfate, many people only associate it with a single scenario, but they don't know it is an "unsung hero" in industries such as industry, agriculture, and new energy. As a manufacturer with 10 years of experience in magnesium sulfate production, we will unlock its four core uses for you today—especially the third one, which holds the key to high-value applications!

First and foremost, it is a "water purification expert" in the industrial field. In electroplating and printing and dyeing wastewater treatment, magnesium sulfate can quickly combine with heavy metal ions to form precipitates, significantly reducing the COD value of wastewater. After an electroplating factory adopted our industrial-grade magnesium sulfate, the heavy metal removal rate reached 98%, and the treatment cost was reduced by 15% compared with traditional agents, successfully meeting emission standards. Its excellent color-fixing effect is also favored by printing and dyeing factories, making fabric colors more durable.

 

It is also a "yield-increasing tool" in agriculture. Magnesium deficiency in soil can cause crop leaves to turn yellow and yield to drop sharply. Agricultural-grade magnesium sulfate has become an ideal magnesium supplement fertilizer due to its good water solubility and high magnesium content. After being used by Shandong apple growers, the fruit tree leaves turned bright green, the fruit setting rate increased by 20%, the fruit sweetness increased by 1.2 degrees, and the repurchase rate has remained above 80% for many years.

 

The most easily overlooked one is its role as a "key additive" in the new energy field. High-purity magnesium sulfate (purity ≥ 99.5%) can be used as an additive in lithium-ion battery electrolytes, increasing the battery cycle life by more than 30%. With the booming development of the new energy industry, the electronic-grade magnesium sulfate customized and produced by us has been supplied to many battery enterprises and has become their core supplier.

 

It also serves as a "safety guarantee" in the pharmaceutical and food fields. Epsom salt made from pharmaceutical-grade magnesium sulfate can relieve constipation, and wet compresses can reduce swelling and pain; food-grade magnesium sulfate is widely used as a stabilizer in bean product processing. All our products have passed national standard certification, and each batch is accompanied by a test report.

 

From industrial water purification to new energy upgrading, the value of magnesium sulfate is far beyond imagination. We support customized production of industrial-grade, agricultural-grade and other specifications of products. We offer factory direct prices and 48-hour delivery.
