Faqs

1. Sodium Dichloroisocyanurate (SDIC) is a high-efficiency solid disinfectant with dichloroisocyanuric acid sodium salt as the active component, usually containing 90% available chlorine. It appears as white powder, granules, or tablets, with strong oxidizing and bactericidal properties. It can rapidly kill bacteria, viruses, fungi, and bacterial spores, and decomposes stably in dry conditions, making it a widely used disinfectant in multiple fields.

1. Water disinfection: Used for swimming pools, drinking water purification, industrial circulating water, and sewage treatment. 2. Public health: Disinfects environments and surfaces in hospitals, schools, hotels, and public toilets. 3. Aquaculture: Sterilizes fish and shrimp ponds to inhibit pathogenic microorganisms and algae growth. 4. Agriculture: Prevents and controls crop diseases as a fungicide for fruits, vegetables, and grains. 5. Emergency epidemic prevention: Used for environmental and water disinfection in disaster-stricken areas and epidemic sites.

1. By physical form: Powder type (fast dissolution, suitable for large-scale dilution), granular type (easy to measure, for automatic feeding), and tablet type (precise dosage, convenient for daily use). 2. By purity grade: Industrial-grade (for sewage treatment, industrial water) and food-grade (for drinking water, food processing). 3. By application: Water treatment-specific, agricultural-specific, and public health-specific.

1. Drinking water disinfection: Add 0.5g SDIC to 1000 liters of water, stir well, and stand for 30 minutes (residual chlorine 0.3-0.5mg/L). 2. Swimming pool disinfection: Add 3-5g SDIC per 100 cubic meters of water, maintain residual chlorine at 0.6-1.0mg/L. 3. Surface disinfection: Dilute 5g SDIC with 10 liters of water, wipe or spray the surface, and air dry after 20 minutes. 4. Aquaculture disinfection: Sprinkle 100-150g SDIC per 1000 cubic meters of pond water, stir evenly, and reapply after 7 days if needed.

1. Store in a cool, dry, and well-ventilated place with temperature ≤30℃, avoiding sunlight and moisture. 2. Keep the package sealed tightly to prevent moisture absorption, decomposition, and loss of available chlorine. 3. Store separately from acids, ammonia, organic substances, and reducing agents to avoid dangerous reactions. 4. Keep away from children and pets, and do not store with food, beverages, or feed.

1. Raw material reaction: React cyanuric acid with sodium hydroxide and chlorine gas under controlled temperature and pressure to generate SDIC. 2. Purification: Remove impurities through crystallization, filtration, and washing to improve product purity. 3. Forming: Process the purified product into powder, granules, or tablets (add stabilizers and binders for tablets). 4. Quality inspection: Test available chlorine content, solubility, and stability, then package after passing the inspection.

1. Personal protection: Wear gloves, goggles, and a mask during operation; avoid direct contact with skin and eyes. Rinse with plenty of water for 15 minutes if contact occurs. 2. Prohibit mixing: Do not mix with acids, ammonia, or organic compounds, as toxic chlorine gas may be produced. 3. Safe operation: Dissolve thoroughly before use; do not use in closed spaces without ventilation. 4. Waste disposal: Dilute unused products with a large amount of water and discharge in accordance with environmental regulations; do not discard directly. 5. Emergency handling: Use dry powder fire extinguishers for fires; do not use water.
