烷基Ketene二聚体蜡

Descreption: Alkyl Ketene Dimer wax, AKD wax, is pale yellow waxy flake solid, it is widly used in paper industry as sizing agent. After sizing with AKD emulsion,it can make paper less water absorbing and controls its printing properties. Specifications Apperance:pale yellow waxy solide Assay:90% min Iodine value (gI2/100g ):45 min Acid value (mgKOH/g) :5 max Melting point,C:48-50 min Physical state: flakes Advantages: Comparing to rosin size, AKD sizing agent is a chemical treatment that reduces machine breakdown and water recycling difficulties of the standard acidic paper manufacture process by minimizing water absorption and enhancing the surface conditions of paper during a neutral paper manufacturing process.AKD plays a significant role in minimizing the detrimental environmental impact of water contamination by facilitating the recycling of water in the paper production process. In particular, the reactive neutral sizing AKD emulsion produced by us has increased the amont of AKD particles per unit volume through effective dispersion,resulting in improved sizing effects in the rang of PH 6.5- 9.0.
