Application Guide
Recommended application method
Water Treatment
- Recommended dosage: 5-50 mg/L (adjust based on water quality).
- Usage: Add directly to the circulating water system
- Effect: Effectively chelates calcium and magnesium ions to prevent scaling
Textile Printing & Dyeing Auxiliaries
- Recommended dosage: 0.5-2 g/L
- Usage: Use with dyes to adjust pH to neutral
- Effect: Chelates metal ions in water, improving dyeing uniformity and color fastness.
Agricultural Fertilization
- Recommended dosage: 1-3 L/acre, dilute 500-1000 times.
- Usage: drip irrigation, flushing, or foliar spray
- Effect: Supplements iron, prevents and treats iron-deficiency chlorosis in crops
Precautions:Store in a dry place, avoid contact with alkaline substances. Use as soon as possible after opening, seal for preservation to prevent deterioration. Specific usage and dosage can be adjusted based on actual process conditions.
