The problem of using dichloroisocyanurate in summer should be noted

- Jun 12, 2019-

In the summer, sodium dichloroisocyanurate is in peak use in the fields of circulating water system, swimming pool disinfection, sewage treatment, aquaculture, etc., and also brings sodium dichloroisocyanurate in applications such as use, transportation and storage. Some questions.

Sodium dichloroisocyanurate is a white crystalline powder with a strong chlorine odor. Contains 56% of available chlorine and a melting point of 225 °C. Soluble in water, and hydrolyzed to hypochlorous acid, the solution is weakly acidic. The pH of the 1% aqueous solution is 5.5 to 7.0. The stability of the aqueous solution is poor. At about 20 ° C, the efficiency can be lost by about 20% in one week; at 30 ° C, it can be lost by about 50%.

Sodium dichloroisocyanurate is not easy to burn. When it is exposed to water or moisture, it can react with water and release a lot of heat. If this reaction cannot be removed in time, it will cause spontaneous combustion of dichloro. The decomposition products are: chlorine gas, carbon dioxide, sodium chloride, ammonia, and nitrogen oxides. At the same time, a large amount of smoke is released, and the decomposition of heat can burn paper, wood, and wood packaging. Also, when mixed with ammonia, ammonium, and amine, it is prone to combustion and explosion. At the same time, the substance is decomposed due to the influence of fire, and harmful gases are released. Therefore, when a fire occurs, firefighters must wear gas masks, put on overalls, and For the fire at the upper air outlet, water and foam fire extinguishing agent can be used.
