Plastic storage tanks for calcium chloride
Calcium chloride (CaCl2) is a highly soluble inorganic compound, a salt with a chemical formula of CaCl2. It is commonly used in plastics as an additive and is also used in fire extinguishers, blast furnaces, and fabric softeners. Calcium chloride is also used in the food industry as a firming agent in canned vegetables and in the production of tofu and caviar substitutes.
When considering the use of plastic storage tanks for calcium chloride, it is important to note that non-metallic materials like plastic are suitable for smaller tanks at near-ambient temperatures. However, their puncture resistance and structural strength relative to carbon steel should be carefully evaluated. Calcium chloride tanks should not be exposed to temperatures greater than 100 degrees Fahrenheit (38 degrees Celsius) during delivery or storage. HDLPE (High-Density Linear Polyethylene) and HDXLPE (High-Density Crosslinked Polyethylene) are commonly used materials for calcium chloride tanks, offering a 1.9 specific gravity rating.
It is crucial to ensure that the tanks are properly vented during liquid transfer to prevent potential tank rupture or collapse. The design of the unloading system depends on factors such as desired unloading time, distance to storage, elevation change, and available utilities. Calcium chloride tanks should be positioned on a smooth, level concrete or asphalt pad to provide adequate support and prevent deflection in the bottom support of the tank.
Additionally, flexible connections are recommended to reduce vibrations from pumps and piping stress on the tank, fittings, and gaskets. The connections, piping, and valves must have structural support independent of the tank's sidewalls and dome. It is important to note that pressure or a vacuum may cause the tank to deform or sustain damage, voiding the tank's warranty. Therefore, proper precautions must be taken to maintain atmospheric pressure in the tank.
In summary, plastic storage tanks can be used for smaller quantities of calcium chloride at near-ambient temperatures, but careful consideration should be given to the tank's structural integrity, ventilation, and support to ensure safe and effective storage.

Plastic piping for handling liquid calcium
Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a white crystalline solid at room temperature and is highly soluble in water. However, there is no clear indication that plastic is soluble in calcium chloride.
Plastic piping is an effective solution for handling liquid calcium. Plastic pipes, specifically PEX pipes, are more resistant to limescale mineral build-up than copper pipes. Limescale, or calcium buildup, is a common issue in plumbing systems, especially in areas with hard water, or water with a high mineral content. PEX piping can handle a wide range of temperatures and pressures, which adds an extra layer of protection against limescale.
PEX pipes are also cost-effective, as they provide higher water flow rates and pressures than copper pipes. They are also safer than copper pipes, as they do not require the use of chemical solutions to remove calcium buildup. These chemical solutions can contain toxic substances and powerful acids or enzymes that can be dangerous and damaging to humans and the environment.
In addition to PEX piping, there are other ways to reduce calcium buildup in pipes. One way is to install a water softener system, which removes or counteracts hard minerals from the water as it enters the home. Another way is to use natural methods such as vinegar or lemon juice, which can effectively break down calcium deposits.
Overall, plastic piping, specifically PEX piping, is a recommended solution for handling liquid calcium due to its resistance to limescale buildup, cost-effectiveness, and safety compared to other types of piping.

Calcium chloride in food plastics
Calcium chloride, an inorganic compound with the chemical formula CaCl2, is a highly soluble salt that is commonly used in the food industry as a firming agent and additive. It is derived from calcium and chlorine and is known for enhancing texture, stability, and flavour in various food applications.
In the food industry, calcium chloride is frequently used as a firming agent to maintain the texture and crispness of canned vegetables, such as canned tomatoes and cucumber pickles. It is also used in firming soybean curds into tofu and in producing a caviar substitute from vegetable or fruit juices. In addition, calcium chloride can be added to the brine or liquid used to preserve pickles, fruits, and vegetables, helping to keep them firm during processing and storage.
Calcium chloride also serves as a stabilizer in food products, aiding in maintaining consistency and preventing undesired changes such as texture degradation or separation of ingredients. This is particularly important in dairy products like cheese, where calcium chloride is used as a coagulant to facilitate curd formation, resulting in a firmer and more compact cheese texture.
Furthermore, calcium chloride can enhance the flavour of certain foods by increasing the perception of saltiness without actually increasing the sodium content. This makes it especially useful in low-sodium or reduced-salt food formulations. Calcium chloride is also used as an additive in sports drinks and other beverages, providing an electrolyte component and adding taste to bottled water.
Outside of the food industry, calcium chloride has numerous applications, including as an additive in plastics, fire extinguishers, blast furnaces, fabric softeners, and swimming pool water. It is also used for de-icing, dust control, and in the production of sodium carbonate and titanium.

Calcium chloride in medicine and health
Calcium chloride (chemical formula CaCl2) is a highly soluble inorganic compound. It is commonly used in medicine and health for the following purposes:
Medicine
Calcium chloride is used as a medication to treat hypocalcemia (low calcium levels in the blood) and hyperkalemia (high potassium levels in the blood). It can also be used as an antidote to magnesium intoxication caused by an overdose of magnesium sulfate. When taken orally, calcium chloride dissociates into calcium ions (Ca2+) in the gastrointestinal tract, resulting in readily bioavailable calcium. This high concentration of calcium ions facilitates efficient absorption in the small intestine.
However, the use of calcium chloride as an oral calcium supplement is less common than other calcium salts due to potential adverse effects such as gastrointestinal irritation and discomfort. Calcium chloride injections are also available and are typically administered in a hospital or clinic setting.
Health and Wellness
In addition to its medicinal uses, calcium chloride is also used in various health and wellness applications. For instance, it is added to swimming pool water to increase the "calcium hardness" value, preventing the water from becoming corrosive to equipment, pumps, and metal fittings.
Calcium chloride is also used as a firming agent in canned vegetables, particularly tomatoes and cucumber pickles, as well as in the production of tofu and fruit or vegetable juice-based caviar substitutes. It helps enhance the texture of various food products, including whole apples, hot peppers, strawberries, diced tomatoes, and peaches.
