company news about Lanyao Water Treatment Co., Ltd. Introduces White Poly Aluminum Chloride (PAC) for Sustainable Papermaking Applications

Lanyao Water Treatment Co., Ltd. is proud to introduce White Poly Aluminum Chloride (PAC) as a game-changing product for the papermaking industry. This high-purity, eco-friendly coagulant is designed to enhance paper quality, optimize production efficiency, and reduce environmental impact. Below are the key roles and advantages of White PAC in modern paper manufacturing:

1. Neutral Sizing Agent for Cost-Effective, High-Quality Paper Production

White PAC replaces traditional aluminum sulfate (alum) as a sizing agent, enabling neutral or alkaline papermaking processes (pH up to 7.5). This innovation allows manufacturers to use low-cost calcium carbonate fillers instead of expensive synthetic materials, reducing production costs by up to 30% while improving paper whiteness, smoothness, and fold resistance568. Unlike alum, White PAC minimizes system corrosion and simplifies wastewater management, aligning with sustainable practices68.

2. Enhanced Retention and Drainage Efficiency

White PAC acts as a superior retention and drainage aid, effectively binding fine fibers, fillers, and additives to improve their retention in paper sheets. This results in faster dewatering, reduced energy consumption during drying, and enhanced paper formation. Its high cationic charge density ensures optimal interaction with anionic particles, boosting both mechanical and optical properties of paper.

3. Improved Environmental Performance

Reduced Chemical Usage: White PAC achieves equivalent or better performance at one-third the dosage of conventional alum, significantly lowering chemical expenses and sludge generation.

Eco-Friendly Formulation: With ultra-low iron content (<0.3% insolubles) and no heavy metals, it produces clear, non-yellowing solutions, ideal for high-grade paper and packaging materials.

Wastewater Purification: It efficiently removes suspended solids and toxic substances from papermaking wastewater, ensuring compliance with environmental regulations.

4. Versatility Across Paper Grades

From newsprint to premium packaging, White PAC adapts to diverse production needs. It enhances ink absorption for sharper print quality, strengthens tear resistance, and stabilizes paper performance in varying humidity conditions.

5. Technical Support and Customization

Lanyao offers tailored solutions, including free water analysis, dosage optimization trials, and on-site technical support, ensuring seamless integration of White PAC into existing papermaking processes.
