Songyuan lime

This product is used in different industries and has different functions. We need to do a good job of sealed storage in the process of daily use. Now, let's see why we need sealed storage. Calcium hydroxide is affected by carbon dioxide in the air. Produce calcium carbonate. It is also based on the principle that the clarified lime water is introduced into carbon dioxide to produce impurities. It is very sensitive to temperature, and the external temperature often changes to some extent. If there are acid substances in the environment.

You can use this reaction. It can also identify what the non-metallic oxide belongs to. Calcium oxide can react with certain salts. It can generate another alkali and another salt. It can react with some acids to form salt and water; It is also a method of making calcium salt, and can also identify acids. Calcium hydroxide plays a role in environmental protection and purification. Calcium hydroxide is a strong alkali, which has the general property of alkali, and can neutralize acidic wastewater or metal wastewater, making acidic wastewater neutral; It can absorb sulfur dioxide in flue gas.

Generally speaking, the setting time of cement will be shortened when the content of free calcium oxide is high. Pure quicklime is added into the cement after single calcination. Because there is no influence of impurities and oxides, it has great hydration. According to the introduction of calcium oxide manufacturers, both initial setting and final setting will be shortened with the addition of free calcium oxide content. Industrial limestone is calcined at high temperature, and its structure is fine and dense under the influence of silica, ferric oxide, aluminum oxide and other substances.
