Exceptional Sizing Efficiency &amp; Heavy Sizing Stability<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">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><\/sup>. The resultant paper gains superior, long-lasting liquid resistance, which significantly extends the physical lifespan and storage durability of finished paper products<sup><\/sup>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Comprehensive Improvement in Paper Quality<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Integrating LY-AKD301 into the wet end elevates multiple critical physical and optical parameters of the paper sheet. It yields noticeable improvements in <strong>whiteness, opacity, printability, and mechanical surface strength<\/strong><sup><\/sup>. This ensures sharper ink definitions and minimizes dusting or picking during high-speed commercial printing runs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Maximum Fiber Cost Optimization via Ground Calcium Carbonate (GCC)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Operating in a reliable neutral sizing environment allows paper mills to completely substitute expensive calcined clay or talc with <strong>heavy ground calcium carbonate (GCC)<\/strong> as a primary filler<sup><\/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><\/sup>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Energy Conservation &amp; Cleaner Wet-End Operations<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">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><\/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><\/sup>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u0420\u0435\u043a\u043e\u043c\u0435\u043d\u0434\u0430\u0446\u0438\u0438 \u043f\u043e \u043f\u0440\u0438\u043c\u0435\u043d\u0435\u043d\u0438\u044e \u0438 \u0434\u043e\u0437\u0438\u0440\u043e\u0432\u043a\u0435<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To capture the highest chemical retention and target Cobb values, implement the following industrial procedures:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Addition Points:<\/strong> LY-AKD301 can be added directly as a concentrate to thick stock or diluted and fed into the stock mixing tank.
