Factory Supply Calcium Sulfate CAS 7778-18-9 With Good Price: User Guide

Basic Information and Parameters

Calcium sulfate with the CAS number 7778 - 18 - 9 is a widely used chemical compound. Its chemical formula is CaSO₄, and it exists in several forms, including anhydrous calcium sulfate (CaSO₄), calcium sulfate dihydrate (CaSO₄·2H₂O, known as gypsum), and calcium sulfate hemihydrate (CaSO₄·0.5H₂O, known as plaster of Paris). The product we supply is of high - quality and comes from the factory at a good price.

Physical properties: Anhydrous calcium sulfate is a white crystalline powder. It is odorless and insoluble in water. Gypsum is a soft mineral with a monoclinic crystal system. It has a density of about 2.32 g/cm³ and a melting point of around 1450 °C. Plaster of Paris is a fine white powder that hardens when mixed with water.

Uses

1. Building and Construction: Calcium sulfate, especially gypsum, is a key material in the construction industry. It is used to make drywall, plaster, and mortar. Drywall made from gypsum provides fire - resistance and sound - insulation properties. Plaster of Paris is used for decorative purposes, such as creating moldings and statues, and for repairing walls and ceilings.

2. Agriculture: Gypsum is used as a soil conditioner. It can improve soil structure by reducing soil compaction and increasing water infiltration. It also provides calcium and sulfur to the soil, which are essential nutrients for plant growth.

3. Food Industry: Calcium sulfate is used as a food additive. It is used as a coagulant in the production of tofu, helping the soy milk to solidify. It can also be used as a firming agent in canned vegetables and a dough conditioner in baking.

4. Medical Field: In dentistry, plaster of Paris is used for making dental molds. In orthopedics, it is used to make casts for broken bones.

Usage

1. For building materials: When using gypsum to make plaster, first, add the appropriate amount of water to the plaster of Paris powder in a clean container. Stir the mixture thoroughly until it reaches a smooth, lump - free consistency. Then, apply the plaster to the surface to be covered using a trowel. For drywall installation, ensure proper alignment and use appropriate fasteners.

2. In agriculture: Spread the gypsum evenly over the soil surface at the recommended rate. Then, till the soil to a depth of 6 - 8 inches to incorporate the gypsum into the soil. Water the soil after application to help the gypsum dissolve and release its nutrients.

3. In food production: When using calcium sulfate as a coagulant in tofu making, dissolve the appropriate amount of calcium sulfate in water. Slowly add the solution to the hot soy milk while stirring gently. Stop adding the solution when the soy milk starts to coagulate.

Case Studies

1. Construction Project: A commercial building project in a large city used our factory - supplied gypsum for drywall installation. The project required high - quality, fire - resistant materials. The gypsum drywall provided excellent fire - protection and sound - insulation, meeting the strict safety and comfort requirements of the building. The use of our gypsum also reduced construction time and costs, as the drywall was easy to install and of consistent quality.

2. Agricultural Farm: A soybean farm in a rural area applied our gypsum as a soil conditioner. Before the application, the soil was compacted, and the soybean yield was low. After applying gypsum at the recommended rate, the soil structure improved significantly. Water infiltration increased, and the soybean plants grew stronger and healthier. The farm saw a 20% increase in soybean yield in the following season.

3. Tofu Factory: A local tofu factory switched to using our calcium sulfate as a coagulant. The tofu produced had a better texture and flavor compared to the previous method. The new coagulant was more efficient, reducing the production time and waste. As a result, the factory increased its production capacity and improved its product quality, leading to higher customer satisfaction and increased sales.

User’evaluation of us

"vivalr is my partner for years. Met at 2014 Shanghai CPHI Expo. Not interested then as had stable supplier. In Sep 2016, original supplier couldn't guarantee quality and delivery. Thought of Zhai and his company first. So far, have stable business relationship and good personal friendship."

Marcus Long

" In years of sourcing from China, first found working with Sincere Chemical great. They help in production, delivery and tech, saving time. When first asking Zhai for optical brightener quote, got detailed one with prices, trade details, company info, R&D and production capacity, packaging and raw material control."

" Hi, I'm Kim, Zhai's partner. Don't like him much (as he never gives more for my prices, haha), but still write customer feedback. Zhai's emails help me understand product and industry. Satisfied with his work ethic. He provides quotes and helps with work details, so I can focus on other things. He's the best supplier for me."
