定义
Aluminum hydroxide polymer is a complex inorganic polymer formed through the controlled hydrolysis and polymerization of aluminum salts. It serves as the active coagulating agent in polyaluminum chloride (PAC) formulations, characterized by its high positive charge density and large molecular structure that enables efficient destabilization of colloidal particles, organic matter, and suspended solids in water treatment processes.
工作原理
The aluminum hydroxide polymer operates through charge neutralization and adsorption-bridging mechanisms. Its high cationic charge neutralizes negatively charged particles in water, while its polymeric structure bridges between destabilized particles to form larger flocs that can be easily removed through sedimentation or filtration.
材料
High-purity aluminum hydroxide with controlled polymerization degreetypically containing 17-24% Al₂O₃ contentwith optimized basicity (OH/Al ratio) between 1.5-2.5 for optimal coagulation performance.

常见问题

What is the difference between aluminum hydroxide polymer and traditional aluminum sulfate coagulants?

Aluminum hydroxide polymer offers higher charge density, wider pH operating range, lower dosage requirements, reduced sludge production, and better performance in cold water compared to traditional aluminum sulfate.

How does basicity affect aluminum hydroxide polymer performance?

Higher basicity (OH/Al ratio) increases polymer size and charge density, improving coagulation efficiency but may reduce stability. Optimal basicity balances performance with product shelf life.
