How do I translate this sentence? Regarding AKD sizing

For reference: The redistribution of AKD over a cellulose fiber surface is an important process in AKD sizing. The redistribution of alkylene dioles on the cellulose surface is a key process in the sizing of cellulose fibers.

After checking, “sizing” refers to “size application.” The redistribution of AKD on the surface of cellulose is an important process in AKD size application. This post was last edited by RainWolf on 2009-2-13 10:28]

Size agent properties: A papermaking additive. It can endow paper and cardboard with ink resistance, water resistance, emulsion resistance, corrosion resistance, etc., to improve smoothness, strength, and handling time. They can be divided into internal sizing agents and surface sizing agents. Internal size agents can be roughly divided into three categories: rosin-based size agents, synthetic size agents, and neutral size agents. Surface sizing agents generally use anionic polymers. AKD (short for alkylene diamine) is a fiber-reactive sizing agent used in paper manufacturing under moderately alkaline conditions; it represents an upgrade to the rosin-based sizing agents. Its reaction mechanism involves AKD emulsion particles (typically 0.2–2 um in size) being fixed to the fiber surface with the help of cationic starch, polyacrylamide, or other monovalent or divalent retention systems. During drying and storage, AKD molecules undergo esterification reactions with the hydroxyl groups on cellulose molecules, thereby completing the sizing process. It is suitable for the production of high-quality cultural papers such as writing paper, coated paper, electrostatic copying paper, and offset paper, as well as papers used for fruit cultivation bags, photographic paper, packaging paper, and cardboard. Compared to acidic sizing agents, alkaline sizing in AKD improves paper strength and toughness, enhances printability, and confers good optical properties and stable chemical properties to the paper. It also helps to save long-fiber raw materials, reduce pulp consumption, and minimize equipment corrosion. The English term for sizing is sizing. I agree with rainwolf’s translation.

Dictionary: sizing agent, adhesive, slurry, sizing agent, sizing compound. Also see: http://www.airiti.com/ceps/ec_en/ecjnlarticleView.aspx?jnlcattype=1&jnlptype=4&jnltype=474&atliid=997151 http://epub.cnki.net/grid2008/detail.aspx?filename=ZGVO199905001075&dbname=CPFD1999

The redistribution of AKD (referring to the emulsion here) on lignocellulose is a key step in the AKD sizing process. ------------------------ Alice Chuh, Yanzhou Tiancheng Chemical Co., Ltd.
