Calcium Chloride Hexahydrate, with the CAS number 7774 - 34 - 7, is a hydrated form of calcium chloride. The chemical formula is CaCl₂·6H₂O. It appears as colorless or white crystals or granules. The molar mass of calcium chloride hexahydrate is approximately 219.08 g/mol. This product has a high solubility in water, which makes it easily dissolve and release calcium and chloride ions into the solution. It also has a relatively low melting point compared to anhydrous calcium chloride. It is hygroscopic, meaning it can absorb moisture from the air, which is an important property for some of its applications. The purity of our high - quality calcium chloride hexahydrate can reach a high level, ensuring its effectiveness in various uses.
1. Deicing: One of the most common uses of calcium chloride hexahydrate is in deicing applications. It can be used on roads, sidewalks, and parking lots during winter. When spread on ice, it lowers the freezing point of water, causing the ice to melt. This helps to improve safety by reducing the risk of slips and falls.
2. Dust Control: In industrial areas, construction sites, and unpaved roads, calcium chloride hexahydrate can be used to control dust. It absorbs moisture from the air and keeps the surface slightly moist, preventing dust particles from becoming airborne.
3. Food Industry: In the food industry, it can be used as a firming agent for fruits and vegetables. It helps to maintain the texture and freshness of the produce, extending their shelf - life. It is also used in some cheese - making processes to improve the curd formation.
4. Refrigeration Brines: Calcium chloride hexahydrate can be used in refrigeration systems as a brine. Its solution has a lower freezing point than water, making it suitable for use in cooling applications.
1. Deicing: For deicing, the product can be spread directly on the ice surface using a spreader. The recommended dosage depends on the thickness of the ice and the ambient temperature. Generally, a higher dosage is required for thicker ice and lower temperatures. After spreading, the ice will start to melt gradually.
2. Dust Control: To control dust, a solution of calcium chloride hexahydrate can be prepared by dissolving the product in water. The solution can then be sprayed on the surface using a sprayer. The concentration of the solution should be adjusted according to the specific conditions of the area to be treated.
3. Food Industry: When used as a firming agent in the food industry, the appropriate amount of calcium chloride hexahydrate should be added to the food product according to the recipe or industry standards. It should be dissolved in water first and then added to the food mixture while stirring gently.
4. Refrigeration Brines: In refrigeration systems, a proper concentration of calcium chloride hexahydrate solution should be prepared and circulated in the system. The concentration needs to be carefully controlled to ensure efficient cooling and prevent corrosion of the equipment.
1. Road Deicing: In a small town, during a severe winter, the local government used calcium chloride hexahydrate to deice the roads. They spread the product early in the morning when the snow started to accumulate. Within a few hours, the ice on the roads had started to melt, and the traffic flow was significantly improved. The use of this product reduced the number of accidents caused by slippery roads, ensuring the safety of the drivers and pedestrians.
2. Construction Site Dust Control: A large construction site was facing a dust problem due to the continuous excavation and movement of heavy machinery. The site manager prepared a calcium chloride hexahydrate solution and sprayed it on the unpaved areas of the site. After the spraying, the amount of dust in the air was significantly reduced, creating a healthier working environment for the workers. This also helped to comply with the environmental regulations regarding dust emissions.
3. Fruit Preservation: A fruit distributor used calcium chloride hexahydrate as a firming agent for strawberries. They soaked the strawberries in a diluted solution of the product for a short period. The strawberries remained firm and fresh for a longer time, reducing the spoilage rate. This allowed the distributor to transport the strawberries over longer distances without significant quality loss.
