Calcium Chloride Better Adsorption Performance And Stability
- Oct 24, 2017 -

Calcium chloride is an inorganic compound, a salt composed of chlorine element and calcium, which is a typical ionic type halide. The characters are white, hard fragments or granules. Slightly bitter, tasteless. Calcium chloride has prominent adsorption ability and low desorption temperature, and has great application prospect in the adsorption and separation of ammonia. However, because calcium chloride is not easy to form a stable porous materials, and gas ammonia contact area is small, and in adsorption, desorption process easy to expand, caking, so it is difficult to put into practice in this regard. The contact area of calcium chloride and ammonia can be greatly improved by loading calcium chloride on high specific surface carrier. It has been found that the composite adsorbent prepared by calcium chloride on molecular sieve has better adsorption performance and stability than single adsorbent.

Calcium chloride, a salt composed of chlorine and calcium elements, is chemically CaCl2. It is a typical ionic halide and is a white solid at room temperature. Its common applications include brine used in refrigeration equipment, road deicing agents and Desiccant. Because it absorbs moisture easily in the air [5], the anhydrous calcium chloride must be sealed in the container for storage. Calcium chloride and its hydrate and solution have important application value in food manufacture, building materials, medicine and biology.

1, used as a multi-purpose desiccant, such as nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases drying. The production of alcohols, esters, ethers and acrylic resins is used as dehydrating agents. Calcium chloride aqueous solution is an important refrigerant for refrigeration and ice-making, which can accelerate the hardening of concrete and increase the cold tolerance of building mortar, and it is an excellent building antifreeze. Used as a port for aerosol and road dust collection agent, fabric fire retardant. Used as a protective agent and refining agent for aluminum-magnesium metallurgy. is the production of color deposition pigments precipitation agent. For waste paper processing deinking. is the production of calcium salt raw materials.

2. chelating agent; curing agent; calcium enhancer; refrigerant for refrigeration; desiccant; anti-junction agent; Bacteriostatic agent; pickling agent; Tissue improver.

3, used as desiccant, road dust collection agent, aerosol, fabric fire retardant, food preservatives and used to make calcium salt

4. Used as lubricant additive

5. Used as analytical reagent

6, mainly used for the treatment of blood calcium reduction caused by hand and foot tetany disease, urticaria, exudative edema, intestinal and ureteral colic, magnesium poisoning, etc.

7, in the food industry as calcium enhancer, curing agent, chelating agent and Desiccant.

8, can increase the cell wall permeability of bacteria.
