Differences between tcca and sdic

Introduction of Trichloroisocyanuric Acid

Trichloroisocyanuric acid is a kind of chlorinated isocyanurate compound, which is an important bleaching agent, chlorinating agent and disinfectant.Compared with traditional chlorination agents (such as liquid chlorine, bleach powder, bleaching powder), it has the characteristics of high effective chlorine content, stable storage and transportation, convenient forming and use, high sterilization and bleaching power, long release of effective chlorine in water, safe and non-toxic, etc., so its development and research have attracted the attention of various countries. Trichloroisocyanuric acid 90% effective chlorine is widely used in industrial water, swimming pool water, hospital, tableware and other fungicides, with a broad prospect for development and utilization. At present, trichloroisocyanuric acid has been widely used in industrial circulating water.Its active chlorine content is 2 ~ 3 times higher than that of bleach.Trichloroisocyanuric acid is the replacement product of bleaching powder and bleaching powder. The ratio of three wastes to bleaching powder is greatly reduced. In advanced countries, it is used to replace bleaching powder.

Introduction of Dichloroisocyanuric Acid

Dichloroisocyanurate sodium dichloroisocyanurate is a white powder or granular solid, which is the most broad-spectrum, efficient and safe disinfectant among oxidized fungicides, and is also the leading product of chloroisocyanurate. It can kill all kinds of pathogenic microorganisms, such as bacterial spores, bacterial propagators and fungi, etc. It has a special killing effect on hepatitis virus, and can kill and strongly inhibit the blue-green algae, red algae, seaweed and other algae in circulating water, cooling tower and pool system.It can kill sulphuric acid reducing bacteria, iron bacteria and fungi in circulating water system.

Fengbai sodium dichloroisocyanurate is widely used in power plant, petroleum, chemical, textile, electronic and other industrial recycling water system sterilization algae, completely kill the system pipe, heat exchanger, cooling tower and other bacteria algae reproduction.Solve the problems of bacteria and algae forming slime, blocking and corroding pipes;In the daily chemical, textile industry is a good performance of bleaching, disinfection fungicide;Disinfection of water bodies and aquaculture sites in animal husbandry and aquaculture;In agricultural planting, a variety of crop fungi, bacteria and other diseases have special effects;In the food and beverage processing industry cleaning and disinfection, as a swimming pool disinfectant and hospitals, hotels and other public disinfection.

Difference Between TCCA And SDIC

At present, the most mainstream swimming pool disinfectant is trichloroisocyanurate. Why not dichloroisocyanurate sodium?

The suspension quantitative germicidal test method was used to compare the germicidal efficacy of two kinds of swimming pool disinfectants.Results sodium dichloroisocyanurate and trichloroisocyanurate aqueous solution containing 150mg/L available chlorine were used.

The average killing log values were 6.71 and 7.62, respectively, for e. coli in suspension treated for 5 min.The average killing logarithms of Staphylococcus aureus in suspension were 5.37 and 6.47, respectively. The effective chlorine containing sodium dichloroisocyanurate and trichloroisocyanuric acid were used to treat candida albicans in suspension for 5 min, and the average killing logarithms were 4.75 and 6.41, respectively.

Sodium dichloroisocyanurate and trichloroisocyanuric acid containing 1500 mg/L available chlorine were used to treat bacillus subtilis black variant spore in suspension for 10 min, and the average killing value was 2.47 and 7.51, respectively.

The conclusion is obvious that under the same effective chlorine concentration, the bactericidal effect of trichloroisocyanuric acid is better than that of sodium dichloroisocyanurate.This is also the reason why trichloroisocyanuric acid can stand out among many swimming pool disinfectants.

Trichloroisocyanuric acid effervescent tablets are a highly effective, low-toxic, broad-spectrum, rapid disinfectant that has been widely promoted internationally.
