High-Performance Alkylketene Dimer (AKD) Neutral Sizing Agent LY-AKD301<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

LY-AKD301 is a premium, high-efficiency Alkylketene Dimer (AKD) emulsion designed to entirely overcome the inherent operational disadvantages associated with traditional acid sizing systems<\/sup>. Available in both Ordinary and High-Temperature-Resistant<\/strong> grades, this advanced chemical agent provides superior sizing efficiency across a massive spectrum of paper grades<\/sup>.<\/p>\n\n\n\n

By establishing permanent covalent bonds with cellulose fibers under neutral-to-alkaline conditions, LY-AKD301 significantly boosts physical paper strength, improves energy efficiency, and maximizes paper mill throughput<\/sup>. It serves as a benchmark solution for contemporary high-speed paper machines prioritizing clean wet-end operations and minimized carbon footprints<\/sup>.<\/p>\n\n\n\n

Ventajas t\u00e9cnicas fundamentales y propuesta de valor<\/h2>\n\n\n\n

1. Exceptional Sizing Efficiency & Heavy Sizing Stability<\/h3>\n\n\n\n

LY-AKD301 features high reactive chemical activity, providing an exceptional sizing effect that allows mills to run heavy sizing configurations without sizing regression or aging degradation<\/sup>. The resultant paper gains superior, long-lasting liquid resistance, which significantly extends the physical lifespan and storage durability of finished paper products<\/sup>.<\/p>\n\n\n\n

2. Comprehensive Improvement in Paper Quality<\/h3>\n\n\n\n

Integrating LY-AKD301 into the wet end elevates multiple critical physical and optical parameters of the paper sheet. It yields noticeable improvements in whiteness, opacity, printability, and mechanical surface strength<\/strong><\/sup>. This ensures sharper ink definitions and minimizes dusting or picking during high-speed commercial printing runs.<\/p>\n\n\n\n

3. Maximum Fiber Cost Optimization via Ground Calcium Carbonate (GCC)<\/h3>\n\n\n\n

Operating in a reliable neutral sizing environment allows paper mills to completely substitute expensive calcined clay or talc with heavy ground calcium carbonate (GCC)<\/strong> as a primary filler<\/sup>. Furthermore, the system\u2019s chemical tolerance permits a higher utilization rate of short fibers and broke (recycled damaged paper) instead of long fibers, dramatically lowering the overall cost per ton of papermaking<\/sup>.<\/p>\n\n\n\n

4. Energy Conservation & Cleaner Wet-End Operations<\/h3>\n\n\n\n

The high fiber affinity of LY-AKD301 decreases refining energy consumption and minimizes steam demands in the drying section, leading to notable energy savings<\/sup>. Additionally, it maintains a cleaner, deposit-free wet-end system, significantly curtails paper machine corrosion, and simplifies white water loop closure to drastically lower wastewater treatment volumes<\/sup>.<\/p>\n\n\n\n
