Magnesium sulfate has various contents and classifications, and can be classified into industrial grade and agricultural grade according to its use. According to the state, it can be divided into magnesium sulfate heptahydrate, magnesium sulfate monohydrate, anhydrous magnesium sulfate, etc. Generally, there are various forms such as crystal particles, powder, spherical particles, etc. Magnesium sulfate is unstable in the air. Magnesium sulfate heptahydrate is prone to dehydration in the air, while anhydrous magnesium sulfate is prone to water absorption.
Industrial Applications
Leather Industry: Used as a filling reinforcement agent to enhance heat resistance.
Printing and Dyeing: Acts as a fabric dyeing agent, weighting agent, and mordant for uniform dyeing.
Fireproof Materials: Serves as a flame retardant for plastics like acrylic resin.
Papermaking: Synthetic additive for ABS and PVC resins.
Organic Chemicals: Used as a desiccant and dehydrating agent in thin cotton and silk processing.
Electroplating: Conductive salt to improve conductivity and coating quality.
Environmental Protection: Used for industrial wastewater treatment to coagulate and settle waste water.
Agricultural Applications
Fertilizer: Direct use as base fertilizer, topdressing, and foliar fertilizer.
Nutrient Boost: High-quality dual nutrient fertilizer to increase yield and improve fruit taste.
Photosynthesis: Magnesium is vital for chlorophyll, promoting protein and fat formation.
Solubility: Higher solubility than other fertilizers, ideal for potted plants like roses and potatoes.
