Description :

　　Bleach powder is a mixture of calcium hydroxide, calcium chloride, and calcium hypochlorite, mainly composed of calcium hypochlorite (Ca (ClO))? ）The effective chlorine content is 30% -38%. Bleach powder is a white or off white powder or particle, with a significant chlorine odor, very unstable, strong moisture absorption, and is easily decomposed by light, heat, water, and ethanol. Bleach powder dissolves in water, and its aqueous solution can turn litmus paper blue, gradually fading and turning white. When exposed to carbon dioxide in the air, hypochlorous acid can be released, while when exposed to dilute carbon dioxide, a large amount is produced. Bleach powder is made by reacting with hydrated lime. Because dry calcium hydroxide does not react, chlorine can only be adsorbed by calcium hydroxide. Therefore, in industry, hydrated lime containing less than 1% free water is used for chlorination, and the water used also contains less than 0.06% water. Utilize the free water in these raw materials to hydrolyze and generate acids (HClO, HCl), which are neutralized by hydrated lime. Subsequently, relying on the water released from calcium hydroxide during the chlorination reaction, chlorine continues to hydrolyze, allowing more calcium hydroxide to participate in the reaction process and generate a series of compounds. Bleach powder is a composite of these compounds.
