AKD wax introduction Chemical name: Alkyl Ketene Dimer Alias: AKD wax AKD powder is also called AKD wax. Chemical name is Alkyl ketene dimer. CAS registration number is 144245-85-2. Appearance is pale yellow flake or granular solid. It is produced by fatty acid (C16), via acylation and dehydrochlorination to become AKD wax. AKD wax is mainly used for papermaking neutral sizing agent. R or R' in the above structural formula is the alkyl group, and a series of alkyl ketene dimers can be obtained through modifying different alkyl groups. Octodecane and cetane are applicable to the papermaking neutral sizing agent. Alkyl ketene dimer is a white-to-yellow solid with the melting point of about 47 ~ 51 , which can be soluble in ethyl alcohol, benzene, chloroform and other organic solvents. The reactive group of alkyl ketene dimer-ketone group has high activity and makes esterification reaction with the hydroxyl in cellulose. Product Application AKD wax can be made into AKD emulsion applied as in sizing agent in the papermaking production. AKD wax is emulsified by the cationic emulsifier, and melted AKD wax and emulsifier undergo high-speed shearing and high pressure homogenization to form the liquid AKD sizing agent after cooled. In the papermaking process, application of AKD sizing agent gives the fluid resistance to paper and paperboard to prevent or delay the penetration and diffusion of some liquids on paper fibers, thus satisfying people's requirements on the processing and use of paper products. AKD contains hydrophobic group and hydrophilic group, which are well distributed in the sizing process to transfer to locate the process of bonding with cellulose. AKD emulsion particles stay between negatively charged paper fibers since they carry with positive charge by virtue of cationic starch and PAM and other retention agents; In the pressing and drying process of the paper machine, these globular AKD particles are easily expanded and distributed on the surface of fibers due to the lower melting point to form a homogeneous cover film; When paper is dried and stored for a period, the active group (lactone ring) on AKD molecule makes the esterification reaction with the hydroxyl on fibers under certain conditions to be binding on fibers in the form of fixed covalent bonds. Hydrophobic long-chain alkyls transfer to the paper surface in order to give the penetration resistance to paper.

AKD wax(Alkyl Ketene Dimer, Simplified: AKD) is a neutral sizing agent, which can directly react with fiber. AKD wax produced by Shandong Tiancheng Chemical Co., Ltd, With high content and low acid value, is more efficient a sizing agent. AKD WAX Advantage 1. Higher purity 2. Lower acid value PRODUCT DESCRIPTION AKD WAX Specification Assay %: 90 min Iodine Number gI2/100g: 45 min Acid Value cPs/25â??: 5.0 max Melting Point: 47 min Appearance: Pale yellow granule Packaging: 25kg/bag Shelf life: 6 months

Cationic reagent QUAT188 are aqueous solutions of monomer (3-chloro-2- hydroxypropyl) trimethylammonium chloride (CHPTAC). Cationic reagent are clear,odorless liquids.It is used to modify natural and syntheti polymers into quaternary ammonium compounds. It is used industrially for chemical processing of personal-care products, pulp and paper, textiles, and for water management. Advantage: The product appearance is transparent liquid, colorless and tasteless, the impurity content is low, is less than 10ppm. Because the use of continuous production process, product quality is stability; The product response rate is higher than 90%.
