Trichloro S Triazinetrione vs Calcium Hypochlorite
Comparison between trichloroisocyanuric acid and calcium hypochlorite
There are two substances today, one is trichloroisocyanuric acid (Trichloro S Triazinetrione), and the other is calcium hypochlorite (Calcium Hypochlorite). Both are commonly used disinfection and bleaching agents. They are used in many fields. However, their properties and uses have similarities and differences. Try to analyze them in detail.
First, physical and chemical properties
Trichloroisocyanuric acid, which is a white crystalline powder or granular solid with strong chlorine odor. It contains extremely high effective chlorine, up to about 90%. It can be rapidly dissolved in water and hydrolyzed to produce hypochlorous acid. Its aqueous solution has excellent stability and can maintain a certain concentration of effective chlorine for a long time.
Calcium hypochlorite, a white powder, has a strong chlorine odor. The available chlorine content is about 60% - 70%. It has strong hygroscopicity and is prone to moisture decomposition in the air for a long time. When it interacts with water, hypochlorous acid is also produced. However, the stability of its aqueous solution is slightly inferior to that of trichloroisocyanuric acid, and the available chlorine is easy to decrease with time.
Second, disinfection and sterilization efficiency
Trichloroisocyanuric acid, due to its high content of available chlorine and stable release characteristics, has strong disinfection and sterilization ability. It has a good killing effect on bacteria, viruses, fungi and other microorganisms. In the disinfection of swimming pool water, it can quickly kill pathogens in the water, and can maintain the water quality clean for a long time to protect the health of swimmers.
Calcium hypochlorite also has significant disinfection and sterilization ability, and has a high-efficiency killing effect on common pathogenic microorganisms. However, due to the rapid release of available chlorine and poor stability of the aqueous solution, in long-term disinfection scenarios, it is necessary to add more frequently to maintain the effective chlorine concentration and ensure the disinfection effect.
Third, application field
Trichloroisocyanuric acid is widely used. In addition to swimming pool disinfection, it is commonly used in drinking water disinfection, hospital sewage disinfection, food processing sites disinfection, etc. Because of its good stability, it is easy to store and transport, and is suitable for a variety of complex environments.
Calcium hypochlorite is also commonly used in drinking water disinfection, industrial circulating water sterilization and algae killing, silkworm disinfection and other However, due to its strong hygroscopicity, it is necessary to pay attention to moisture-proof when storing, and apply it in a high humidity environment, or special treatment is required to ensure the effect.
Fourth, safety
Although trichloroisocyanuric acid has good disinfection effect, it is corrosive to a certain extent. If the concentration is too high or the operation is improper, it may cause irritation to human skin and mucous membranes. When used in a poorly ventilated place, the chlorine gas produced by its decomposition may cause respiratory discomfort.
Calcium hypochlorite is also corrosive, and it is easy to produce a large amount of chlorine gas in case of acid, which has the potential risk of poisoning. When using, it is necessary to strictly follow the operating procedures and take protective measures.
To sum up, trichloroisocyanuric acid and calcium hypochlorite In practical applications, when selected according to specific needs, environmental conditions and other factors, in order to achieve the best disinfection, bleaching and other effects, and ensure the safety of the use process.
