I. Product Features

　　Sodium dichloroisocyanurate dihydrate is a highly effective, low-toxicity, broad-spectrum, and fast-acting disinfectant and bactericide. It emits a milder odor, maintains its active chlorine content for a longer duration, exhibits greater chemical stability, and delivers more prolonged disinfection effects. This compound can rapidly and efficiently eliminate a wide range of bacteria, fungi, spores, molds, Vibrio cholerae, and other harmful microorganisms. Notably, it is particularly effective against hepatitis A and hepatitis B viruses, while also demonstrating remarkable efficacy against sexually transmitted diseases and HIV. Additionally, sodium dichloroisocyanurate dihydrate boasts impressive capabilities in algae control, odor removal, water purification, and bleaching.

IV. Usage and Dosage

　　1: Drinking water disinfection: Add 5 grams per cubic meter of water, stir well, let it sit for a while, and prepare fresh solution each time before use.

　　2: Swimming Pool Disinfection: Add approximately 10–15 grams per cubic meter daily to the pool, ensuring that the residual chlorine level remains consistently between 1.0 and 1.5.

　　3: Disinfection of hospital wards, hospital waste, and medical instruments: Add 10 grams per liter, and after complete dissolution, either soak or spray the surfaces.

　　4: Disinfection of public places and spaces: Add 5 grams per liter, and after complete dissolution, use for wiping or spraying. Allow it to act for 10–30 minutes—this effectively kills bacterial spores.

　　5: Dining Utensils: Add 0.5–1.0 grams per liter, ensuring complete dissolution before soaking; allow an action time of 15–30 minutes.

　　6: When using Dichloroisocyanurate as a biocide in circulating cooling water systems, add 15–20 ppm every 2–3 days during summer. In spring and autumn, apply once every 3–5 days, and in winter, add it every 5–7 days. To ensure effective biocidal performance, non-oxidizing fungicides can also be added periodically.

　　7: Disinfection of infectious disease areas and post-disaster contaminated zones: Add 2-5 grams per liter, ensure complete dissolution before spraying, and allow a contact time of at least 30 minutes.

　　8: For disinfecting feces and other excreta, add 40–60 grams per liter and allow it to act for 1–2 hours.
