• Treatment of iron-containing wastewater from steel plants

• Rapid dissolution even at low temperatures (0–5°C)

• Demulsification of oily wastewater

• Can be used in combination with polyacrylamide (PAM)

High-end industrial and consumer goods sectors

• Pharmaceuticals: auxiliary for vaccine clarification

• Cosmetics: astringent and suspension stabilizer

• Precision casting: shell reinforcement for investment casting

• Leather processing: improves leather softness by over 20%

Dissolution and Usage Methods

• Dissolve the solid product with water at a 1:3 ratio

• Further dilute 10–30 times before use

• Common solution concentration: 5%–10%

• Effective pH range: 5–9, optimal at 6–8

• Rapid mixing for 10–30 seconds after dosing

• Sedimentation time: approximately 30–60 minutes

Precautions

• The solution is mildly corrosive; corrosion-resistant equipment is recommended

• Avoid mixing products from different manufacturers or grades

• Use clean water at room temperature for dissolution

• Shelf life is 12 months; moisture absorption does not affect usability

Packaging and Storage
