Basic Information and Parameters

Calcium sulfate (CaSO₄) is a widely used inorganic compound with the CAS number 7778 - 18 - 9. It exists in several forms, including anhydrous calcium sulfate (CaSO₄), calcium sulfate dihydrate (CaSO₄·2H₂O, also known as gypsum), and calcium sulfate hemihydrate (CaSO₄·0.5H₂O, commonly called plaster of Paris). The molecular weight of anhydrous calcium sulfate is approximately 136.14 g/mol, while that of calcium sulfate dihydrate is around 172.17 g/mol.

Our factory - supplied calcium sulfate is of high purity, meeting strict quality control standards. It usually appears as a white crystalline powder or solid. The product is odorless and has a relatively low solubility in water, with solubility varying depending on the form and temperature.

Uses of Calcium Sulfate

1. Construction Industry: Calcium sulfate, especially gypsum, is a crucial raw material for making plasterboard, plaster, and wallboard. Plasterboard is widely used in interior partitioning and ceiling construction due to its fire - resistance, sound - insulation, and easy installation properties. Gypsum plaster can be used for smooth finishing of walls and ceilings.

2. Agriculture: It is used as a soil conditioner. Calcium sulfate can improve soil structure, especially in clayey soils, by reducing soil compaction and increasing water infiltration. It also provides calcium and sulfur nutrients to plants, which are essential for plant growth and development.

3. Food Industry: In the food industry, calcium sulfate is used as a coagulant in the production of tofu. It helps in the formation of curds from soy milk, making it an important ingredient in the tofu - making process. It is also used as a calcium supplement and a firming agent in some food products.

4. Medical Field: Plaster of Paris, a form of calcium sulfate hemihydrate, is commonly used in orthopedics for making casts to immobilize broken bones during the healing process. It sets quickly and provides a rigid support structure.

How to Use Calcium Sulfate

1. Construction: When using calcium sulfate - based plaster or plasterboard, follow the manufacturer's instructions carefully. For plaster, mix it with the appropriate amount of water to achieve the desired consistency. Apply it evenly on the surface using a trowel. When installing plasterboard, ensure proper spacing and secure it firmly to the framing.

2. Agriculture: For soil conditioning, spread the calcium sulfate evenly over the soil surface. The application rate depends on the soil type and its nutrient status. Generally, it can be applied at a rate of 100 - 500 kg per hectare. After application, till the soil to incorporate the calcium sulfate into the root zone.

3. Food Industry: In tofu production, dissolve the appropriate amount of calcium sulfate in water to make a solution. Slowly add the solution to the soy milk while stirring gently. The curds will start to form, and then they can be separated from the whey.

4. Medical Field: In orthopedics, the plaster of Paris is first soaked in water until it reaches a workable consistency. Then it is wrapped around the affected limb in multiple layers. Care should be taken to ensure proper molding around the limb and to avoid any pressure points.

Usage Case Studies

1. Construction Case: A large - scale commercial building project used our factory - supplied gypsum plasterboard for interior partitioning. The plasterboard's high - quality finish and fire - resistance properties met the strict building codes. The ease of installation also saved a significant amount of construction time, resulting in cost savings for the project.

2. Agriculture Case: A farm in a region with heavy clayey soil applied our calcium sulfate as a soil conditioner. After several months, the soil structure improved significantly, with better water infiltration and aeration. The crops showed improved growth and higher yields, especially in vegetables and grains.

3. Food Industry Case: A tofu - making factory switched to our high - purity calcium sulfate as a coagulant. The resulting tofu had a better texture, higher yield, and longer shelf - life. The factory was able to increase its production efficiency and customer satisfaction.

4. Medical Field Case: A hospital used our plaster of Paris for making casts for patients with broken
