Product Description

Information

Multifunctional magnesium sulfate monohydrate, with its high purity (typically ≥98%), low water of crystallization, strong water solubility, and good flowability, is efficiently applied in agriculture, industry, medicine, and daily chemicals. It serves multiple functions including nutrient supplementation, processing, conditioning, and adjuvant therapy. The following are key information and application scenarios:

Key Characteristics and Specifications

· Chemical Formula: MgSO₄・H₂O, Molecular Weight 138.38, CAS: 14168-73-1.

· Appearance: White crystalline powder or granules, good flowability, not prone to clumping, stable during storage and transportation.

· Solubility: Easily soluble in water, solution is nearly neutral, easy to prepare and apply.

· Purity and Content: Agricultural/industrial grade typically ≥98%, Mg approximately 17%, S approximately 17%; pharmaceutical/daily chemical grade has higher purity and lower impurities.

Multi-domain Functions and Applications

Agriculture: High-efficiency dual-element fertilizer and soil conditioner

·Nutrition Supplementation: Magnesium is the core of chlorophyll, promoting photosynthesis and enzyme activation; sulfur participates in the synthesis of amino acids and vitamins, improving yield and quality.

·Application Methods:

·Base Fertilizer: Mix with organic fertilizer and broadcast, 10–13 kg per acre, to improve soil.

·Topdressing: Furrow application or fertigation, 250–500 g per fruit tree.

·Follicular Fertilizer: 0.5%–1.0% for fruit trees, 0.2%–0.5% for vegetables, sprayed 2–3 times consecutively.

·Suitable Crops: Rice, citrus, potatoes, tomatoes, roses, and other magnesium-loving crops.

·Compound Fertilizer Additive: As an anti-caking agent, adding 1%–2% can reduce moisture, improve fluidity, and enhance fertilizer efficiency.

Industry: Processing Raw Materials and Auxiliaries

·Building Materials: Production of magnesium sulfate cement, high strength, fireproof, used for fireproof boards and partitions.

• Chemical Industry: Preparation of magnesium salts such as light magnesium carbonate and magnesium hydroxide, used as auxiliaries in ABS/PVC synthesis.

• Printing and Dyeing: Developing salts for blue dyes, alkali absorbents for black dye liquor, maintaining pH 6.5–7 to ensure uniform dyeing.

• Papermaking: Pulp treatment to improve strength and regulate cooking pH.

• Water Treatment: Adsorption of impurities, aiding in softening and purification.

• Desiccants: Stabilizes water of crystallization, suitable for small-scale moisture-proof storage.

Pharmaceuticals and Daily Chemicals: Conditioning and Health Products

• Pharmaceuticals: Oral laxatives, magnesium supplements; intravenous use for eclampsia and hypertensive crisis (requires physician guidance).

• Daily Chemicals: Bath salts, foot bath solutions to soothe muscles and improve rough skin; added to shampoos to reduce oiliness and soften hair.

Feed and Others

• Feed Additives: Supplementing magnesium to promote bone development and enzyme activity in livestock and poultry; approximately 0.2% for ruminants, 0.04%–0.06% for non-ruminants. Other applications: Artificial snowmaking, leather filling agent, analytical reagent, etc.

Advantages compared to other magnesium sulfate products:

Highly efficient for storage and transportation: Low water content, less prone to moisture absorption and clumping, good fluidity, easy for mechanical fertilization and industrial formulation.

Controllable solubility: Superior to Anhydrous Magnesium Sulfate, avoids excessively high local concentrations, suitable for fine processing applications.

High cost-effectiveness: Balances purity and cost, requires less dosage than low-purity products, reduces overall cost for long-term bulk use.

Precautions for use:

Agriculture: Micronutrient fertilizer, avoid excessive dosage. Liquid fertilizer concentration ≤0.5 g/L; when mixed with farmyard manure, magnesium sulfate ≤50 kg per 1500 kg of farmyard manure.

Pharmaceuticals: Use with caution in patients with renal insufficiency. For intravenous administration, monitor knee tendon reflex, respiration, and urine output. Excessive dosage may cause hypermagnesemia.

Industry: Strictly control dosage and pH in printing and dyeing and papermaking to avoid affecting product quality.
