Introduction<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The global paper industry has undergone a profound transformation over the past three decades, shifting decisively from traditional acidic rosin-alum sizing systems to neutral and alkaline papermaking technologies. At the heart of this revolution lies Alkyl Ketene Dimer (AKD)\u2014a reactive synthetic sizing agent that has become the internal sizing agent of choice in the paper and pulp industry. First developed by Hercules Inc. in the 1950s and produced at industrial scale since 1956, AKD has evolved from a specialty chemical for high-water-resistance papers into a core component of modern papermaking systems worldwide.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>LY Chem Technology Co., Ltd.<\/strong> , a leading paper chemicals manufacturer based in Central China with over two decades of industry experience, offers a comprehensive range of AKD neutral sizing solutions designed to meet the diverse needs of modern papermakers. Our LY-AKD301 internal sizing agent and LY-AKD302 surface sizing agent represent the culmination of years of research and process optimization, delivering superior water resistance, enhanced paper strength, and exceptional operational reliability across a wide spectrum of paper grades\u2014from cultural paper and packaging board to specialty food-contact papers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This technical article explores the science behind AKD neutral sizing, its advantages over traditional acidic systems, and the key performance characteristics that make it indispensable for modern paper production.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">2. The Science of AKD Sizing: Mechanism of Action<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">2.1 Chemical Structure and Reactivity<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">AKD is a light yellow waxy solid belonging to the class of reactive sizing agents. Chemically, it is an unsaturated lactone featuring a characteristic four-membered lactone ring with two long-chain alkyl side groups. This unique molecular architecture enables AKD to form strong covalent bonds with cellulose fibers\u2014a fundamental distinction from traditional rosin-based sizing agents, which rely primarily on physical deposition and ionic interactions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2.2 The Covalent Bonding Mechanism<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">During the sizing process, the lactone ring of the AKD molecule reacts with hydroxyl (-OH) groups present on cellulose fiber surfaces to form \u03b2-keto ester bonds. This esterification reaction anchors the hydrophobic alkyl chains firmly to the fiber surface, with the long carbon chains oriented outward. The result is a permanent, water-repellent hydrophobic layer that significantly improves the paper\u2019s resistance to water penetration, ink bleed, and wrinkling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Importantly, this covalent bond is strong enough to resist attack by acids or bases, providing exceptional durability and aging resistance. Studies have shown that very little reacted AKD is required to achieve effective sizing\u2014typical addition levels range from 0.05% to 0.2% AKD formulation based on dry fiber weight.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2.3 Retention and Curing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The first step toward effective sizing is optimum retention of AKD particles on fiber surfaces, believed to occur through heterocoagulation of cationic particles to negatively charged fiber surfaces. Fast-cure type AKD variants with higher cationicity have demonstrated superior sizing performance even at low addition levels and without extended curing treatment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Drying conditions also play a critical role\u2014temperatures above 100\u00b0C are desirable for developing optimal sizing degree. While traditional AKD sizing typically requires 24\u201348 hours to fully cure at room temperature, modern fast-cure formulations have significantly reduced this curing time, enabling faster production turnaround.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">3. AKD vs. Traditional Acidic Sizing: A Paradigm Shift<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">3.1 The Limitations of Acidic Sizing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Traditional rosin-alum sizing operates under acidic conditions (pH 5.5\u20136.5) and presents numerous disadvantages that have driven the industry toward neutral alternatives:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>\u041f\u043e\u0436\u0435\u043b\u0442\u0435\u043d\u0438\u0435 \u0438 \u0445\u0440\u0443\u043f\u043a\u043e\u0441\u0442\u044c \u0431\u0443\u043c\u0430\u0433\u0438<\/strong>: Acidic conditions promote fiber hydrolysis, leading to paper that yellows over time and becomes brittle.<\/li>\n\n\n\n<li><strong>\u041a\u043e\u0440\u0440\u043e\u0437\u0438\u044f \u043e\u0431\u043e\u0440\u0443\u0434\u043e\u0432\u0430\u043d\u0438\u044f<\/strong>: The acidic environment accelerates corrosion of paper machine components, increasing maintenance costs and reducing equipment lifespan.<\/li>\n\n\n\n<li><strong>\u041d\u0435\u0432\u043e\u0437\u043c\u043e\u0436\u043d\u043e\u0441\u0442\u044c \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u043d\u0438\u044f \u043d\u0430\u043f\u043e\u043b\u043d\u0438\u0442\u0435\u043b\u0435\u0439 \u043d\u0430 \u043e\u0441\u043d\u043e\u0432\u0435 \u043a\u0430\u0440\u0431\u043e\u043d\u0430\u0442\u0430 \u043a\u0430\u043b\u044c\u0446\u0438\u044f<\/strong>: Acidic systems cannot accommodate alkaline fillers such as calcium carbonate, which are significantly more cost-effective than traditional fillers like talc or titanium dioxide.<\/li>\n\n\n\n<li><strong>Higher environmental load<\/strong>: Acidic papermaking generates higher white water pollution and requires more aluminum sulfate.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3.2 Advantages of AKD Neutral Sizing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">By contrast, AKD neutral sizing offers a comprehensive set of benefits that align with modern papermaking requirements:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Superior Paper Quality<\/strong>: AKD-sized papers exhibit improved brightness (whiteness increase of +5% to +8% ISO), enhanced opacity (+10% to +15%), and better bulk. The absence of acid-induced fiber degradation means tensile strength improves by 10%\u201315% and folding endurance increases by up to 20%.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Extended Paper Permanence<\/strong>: Neutral-sized papers do not suffer from the yellowing and embrittlement characteristic of acidic papers. The presence of alkaline fillers like calcium carbonate provides an added measure of permanence by absorbing acidic gases from the environment that might otherwise cause paper deterioration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Reduced Environmental Impact<\/strong>: AKD systems eliminate or dramatically reduce aluminum sulfate usage (by 80%\u2013100%), lower COD discharge per ton of paper by 40%\u201360%, and support compliance with stringent environmental regulations such as EU REACH.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Operational Efficiency<\/strong>: Neutral papermaking reduces equipment corrosion, extends machine service life, and enables the use of higher filler loadings\u2014all while maintaining sheet strength.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Cost Optimization<\/strong>: While AKD itself may have higher raw material costs than rosin, the overall system economics are favorable. AKD enables the use of calcium carbonate fillers (30%\u201350% cheaper than talc), reduces the need for optical brighteners, and in neutral\/alkaline conditions has proven 20%\u201325% more cost-effective than rosin alternatives.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">4. Key Performance Characteristics of LY Chem AKD Sizing Solutions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">4.1 Rapid Sizing Development<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Our LY-AKD301 and LY-AKD302 formulations are engineered to achieve effective sizing early in the drying section of the paper machine. Unlike conventional AKD products that may require extended curing periods, our advanced emulsions deliver superior sizing performance with minimal delay\u2014wet paper sheets already exhibit good performance at the size press stage. Fast-cure technology, characterized by higher cationicity, enables better sizing degree even at low addition levels and without extended curing treatment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4.2 Excellent Emulsion Stability<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">One of the persistent challenges with AKD sizing has been emulsion stability and the tendency for hydrolysis reactions to reduce sizing effectiveness. LY Chem\u2019s AKD emulsions feature optimized stabilization systems that minimize hydrolysis and maintain consistent performance throughout the papermaking process. The long alkyl chain length of our AKD formulations contributes to relatively low hydrolysis rates and superior emulsion stability compared to alternative sizing agents.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4.3 Elimination of Surface Slipperiness and Hydrolysis Issues<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Traditional AKD sizing has occasionally been associated with surface slipperiness (the \u201cslip\u201d problem) and hydrolysis-related performance degradation. Our formulations are specifically designed to overcome these challenges, ensuring that:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>No surface slipperiness occurs after sizing application<\/li>\n\n\n\n<li>Hydrolysis reactions are minimized, preserving sizing effectiveness<\/li>\n\n\n\n<li>Consistent, reliable performance is maintained across varying operating conditions<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4.4 Simplified Application with Reduced Additive Dependency<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">While AKD typically benefits from retention aid systems, our formulations are engineered for robust performance even with simplified additive packages. The high cationicity of our products promotes effective retention on fiber surfaces without requiring complex multi-component retention systems. When used with appropriate fixing agents, sizing degree improves significantly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4.5 Enhanced Paper Physical Properties<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Papers produced with LY Chem AKD sizing exhibit superior tactile and physical characteristics:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Improved elasticity<\/strong>: Paper feels smooth and refined, with enhanced flexibility<\/li>\n\n\n\n<li><strong>Superior printability<\/strong>: Even ink absorption and excellent print clarity<\/li>\n\n\n\n<li><strong>Enhanced durability<\/strong>: Resistance to yellowing and aging over long-term storage<\/li>\n\n\n\n<li><strong>Higher strength properties<\/strong>: Improved ring crush strength and burst strength (particularly relevant for packaging grades)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4.6 Broad pH and Pulp Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">LY Chem AKD sizing solutions perform effectively across a wide pH range (7.0\u20139.0), with optimal performance at pH 7.5\u20138.5. Our products are compatible with:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Diverse fiber sources<\/strong>: Wood pulp, straw pulp, recycled fiber (OCC\/waste paper), and non-wood alternatives<\/li>\n\n\n\n<li><strong>Calcium carbonate fillers<\/strong>: Both precipitated calcium carbonate (PCC) and ground calcium carbonate (GCC) can be used without interfering with sizing performance<\/li>\n\n\n\n<li><strong>Various paper grades<\/strong>: Cultural paper, board paper, newsprint, fruit bag paper, packaging paper, and food-contact papers<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">5.
