TCCA production process---------Sodium dichloroisocyanurate (sDc) deep chlorination method
Sodium dichloroisocyanurate is one of the chlorinated isocyanuric acid series products. In the joint production of SDC and TAAC, cyanuric acid and sodium hypochlorite solution are reacted at 20 to 25°C to generate SDC, and then it is deeply chlorinated to generate TCCA. The reaction formula is:
In this process, NCl3 is inevitably generated. In foreign countries, the production process of TCCA has been further improved, such as adding surfactants to improve the dispersion of CA in the reaction solution, so as to obtain products with more uniform quality; adding wetting agents and anti-foaming agents to control the particle size and make the product It is easy to filter and dry, and the dosage form of the product is also changed from a simple
The powder has been developed into multi-dose forms such as rods and granules.
Trichloroisocyanuric acid (TCCA) is one of the important varieties of chlorinated isocyanuric acid products. It is a new generation of high-efficiency bleaching agent, chlorinating agent and disinfectant. It has the characteristics of safe umbrella and long time to release effective chlorine in water.
