Calcium formate is the calcium salt of formic acid. A chemical component that is practically not found in nature and is rarely formed in some natural minerals. Has the formula Ca(HCOO)2. May have several names: calcium formic acid, HCOOH, calcium formate, E238, calcium formate.
Calcium formate is widely used in construction, chemical and food industries.
According to its physical properties, calcium formate is a white powder of a fine fraction, technical calcium formate can have gradations from white to gray. Produced in Russia, Sweden and China. The smell is not expressed. Formic calcium dissolves well in water and decomposes at a temperature of 300 ° C.
The main property of calcium formate is its hydrophilicity, the ability of the substance to interact with water, to absorb, which allows it to be used as a water removal mechanism. When calcium formate reacts with strong acids, calcium and formic acid salts are formed.
One of the most famous areas of application of calcium formate is its use as an additive in concrete, glue, plaster, which has strongly pronounced antifreeze properties. Calcium formate allows you to work at low temperatures, increasing the strength of the material used.
Features of the use of calcium formate in construction:
• applied to reinforced and non-reinforced concrete.
• can be used for different types of plaster and tile adhesive.
• low consumption, 2-4% of the total mass is used.
• dependence of the consumption volume on the ambient temperature.
• organic. The absence of chlorine in the composition has made calcium formate an environmentally attractive component for use in construction and road sectors.
Storage of calcium formate should be carried out in covered areas protected from direct sunlight and moisture. Despite the fact that the substance is not combustible and not explosive, the use of open flames and smoking in storage warehouses is prohibited. The requirement for increased tightness is applied to packages, since the substance absorbs moisture.
Calcium formate packs are supplied in 25 kilograms. Transportation is carried out in accordance with the hazard class.
