What are the uses of calcium hydroxide?

Thread Content

It is important to have a good understanding of the 6 most common uses of it. Next, let’s take a look at information regarding manufacturers of calcium hydroxide: 1. It can be used as a raw material for producing calcium carbonate. 2. Calcium hydroxide is alkaline, and therefore can be used to reduce soil acidity, thereby improving the soil structure. Bordeaux mixture in pesticides is prepared by mixing lime milk (calcium hydroxide dissolved in water) with an aqueous solution of copper sulfate in a specific ratio. To protect trees from insects during winter, apply lime slurry 80 centimeters above the roots of the trees. 3. Products with high purity and brightness are mainly used in the production of epichlorohydrin and propylene oxide. 4. It can be used in rubber and petrochemical additives; for example, in the petroleum industry it is added to lubricants to prevent coking and sludge deposition, as well as to provide corrosion protection. 5. Used in the production of bleaching powder, bleaching liquor, disinfectants, acidifiers, astringents, water softeners, agents to prevent soil acidity, depilatories, buffers, neutralizers, curing agents, etc. 6. Calcium hydroxide also reacts with carbon dioxide in the air to form calcium carbonate, which is insoluble in water. In sugar production, calcium hydroxide is first used to neutralize the acids in the syrup; thereafter, carbon dioxide is introduced to react with the remaining calcium hydroxide, forming a precipitate that is filtered out, thereby reducing the acidity of the sugar.
