1. Product Overview

W&Q's Zinc sulfate monohydrate (chemical formula: ZnSO₄·H₂O) is a white crystalline powder with a slight astringent taste, belonging to inorganic zinc compounds. It is a naturally derived or chemically synthesized micronutrient product, characterized by high purity, stable chemical properties, and excellent bioavailability.

As an essential zinc source, it plays a crucial role in regulating physiological processes of plants, animals, and humans, and is widely applied in agriculture, animal husbandry, industry, pharmaceuticals, and food sectors. With its balanced performance, cost-effectiveness, and environmental friendliness when used as directed, it has become a preferred zinc supplement in various industries globally.

2. Product Benefits

W&Q's Zinc sulfate monohydrate boasts multiple competitive advantages that make it stand out among zinc supplements, catering to diverse application needs with reliable performance.

2.1 Superior Purity and Zinc Content

Compared with other zinc sulfate forms (such as heptahydrate), it has a higher zinc content (up to 35% minimum) and lower water content. This ensures efficient zinc supply per unit weight, reducing transportation and storage costs while minimizing waste, especially for large-scale applications.

2.2 Excellent Stability and Shelf Life

It is less hygroscopic, not easy to agglomerate, and can maintain its crystalline form and activity for a long time under normal storage conditions. The stable chemical properties prevent decomposition or deterioration, ensuring consistent performance across different usage scenarios and extending the product’s shelf life.

2.3 High Bioavailability

In agricultural and animal husbandry applications, zinc sulfate monohydrate is easily absorbed and utilized by plants and animals. It can quickly supplement the zinc element needed for growth, avoiding zinc deficiency symptoms without causing excessive accumulation or environmental pollution, thus supporting healthy growth cycles.

2.4 Versatile Application Scope

It is low-toxic when used as directed and compatible with most fertilizers, feeds, and industrial raw materials. This versatility allows it to be seamlessly integrated into diverse production processes without causing adverse reactions or reducing the quality of end products.

2.5 Cost-Effective Solution

With high zinc concentration and stable performance, it provides a cost-efficient way to meet zinc supplementation needs. Compared to organic zinc supplements, it offers comparable effectiveness at a lower cost, making it ideal for large-scale industrial, agricultural, and breeding operations.

3. Usage

3.1 Animal Husbandry Applications

As a feed additive, it effectively supplements zinc for livestock and poultry, supporting growth, enhancing immunity, and preventing zinc deficiency-related diseases.

Poultry: Add 50-100mg per kg of feed for chickens, ducks, and geese. It improves egg production rate, eggshell quality, and hatchability, and prevents skin inflammation and feather loss.

Livestock: Add 80-150mg per kg of feed for pigs, cattle, and sheep. It promotes weight gain, enhances feed conversion rate, and prevents hoof rot, dermatitis, and reproductive disorders.

Aquaculture: Add 0.3-0.5mg/L to fish ponds to supplement zinc for aquatic organisms (such as fish and shrimp), improve survival rate, and promote healthy growth. It also helps maintain water quality balance.

3.2 Industrial Applications

Chemical Industry: Used as a raw material for the production of other zinc compounds (such as zinc oxide, zinc stearate), and as a catalyst in chemical reactions.

Textile Industry: Used for fabric dyeing and printing, as a mordant to improve color fastness and brightness of dyed fabrics.

Coating Industry: Added to coatings and paints to enhance corrosion resistance, adhesion, and durability of the coating film.

Other Fields: Used in water treatment to remove heavy metals and turbidity; in the production of electrolytic zinc; and as a preservative in wood processing.

3.3 Pharmaceutical and Food Applications

In the pharmaceutical industry, it is used to prepare zinc supplements (tablets, oral liquids) for treating zinc deficiency in humans. In the food industry, it is used as a food fortifier, added to dairy products, cereals, and health foods to increase zinc content, in strict compliance with national and international food safety standards.

4. FAQ

4.1 Is zinc sulfate monohydrate toxic? How to ensure safe use?

It is low-toxic when used as directed. However, excessive intake or direct contact with eyes/mucous membranes may cause irritation. When using, wear protective gloves, masks, and goggles; avoid eating, drinking, or smoking. If it comes into contact with skin or eyes, rinse immediately with plenty of water. Keep it out of reach of children and pets. In case of accidental ingestion, seek medical attention promptly.

4.2 What is the difference between zinc sulfate monohydrate and heptahydrate?

The main differences lie in water content and zinc content: monohydrate contains 1 crystal water, with zinc content of ~35%, while heptahydrate contains 7 crystal waters, with zinc content of ~21%. Monohydrate is more stable, less hygroscopic, and suitable for long-term storage and large-scale applications; heptahydrate is more soluble in water but prone to agglomeration, suitable for scenarios requiring rapid dissolution and short-term use. Monohydrate is more cost-effective for high-zinc-demand applications.

4.3 How to store zinc sulfate monohydrate correctly?

Store in a cool, dry, well-ventilated warehouse, away from moisture, heat sources, and direct sunlight. Keep it sealed in original packaging to prevent absorption of moisture and agglomeration. Do not store with strong acids, alkalis, or oxidants to avoid chemical reactions. The storage period is usually 2 years under proper conditions; check for agglomeration or discoloration before use.

4.4 Can zinc sulfate monohydrate be mixed with other fertilizers/feeds?

Yes, it is compatible with most common fertilizers (such as nitrogen, phosphorus, potassium fertilizers) and feeds. However, avoid mixing with strong alkaline substances (such as lime, ammonia water) or phosphate fertilizers with high calcium content, as this may cause zinc precipitation and reduce effectiveness. It is recommended to conduct a small-scale compatibility test before large-scale use.

4.5 Will excessive use cause environmental pollution?

Excessive use in agriculture may lead to zinc accumulation in soil and water, affecting ecological balance. Follow the recommended dosage strictly; for agricultural applications, adjust the dosage according to soil zinc content and crop demand. In industrial and breeding applications, treat waste water and residues properly to meet environmental discharge standards, avoiding pollution.

4.6 What is the solubility of zinc sulfate monohydrate in water?

It is highly soluble in water. The solubility at 20℃ is about 54g/100mL water, and solubility increases with temperature. When preparing solutions, stir thoroughly to accelerate dissolution; avoid using hot water above 80℃ for a long time to prevent partial decomposition.

4.7 Is zinc sulfate monohydrate suitable for organic farming?

Yes, it can be used in organic farming as a mineral micronutrient supplement, provided it meets the standards of organic agriculture (no synthetic additives, compliant with organic certification requirements). It is widely used in organic crop cultivation to correct zinc deficiency and improve product quality.
