AKD WAX, AKD1840, AKD1865, AKD1895, ALKYL KETENE DIMER

Product Description

General product information:
       Common Name: AKD wax
       Chemical Name: Alkyl Ketene Dimer
       CAS: **********2
       AKD and ASA have become more frequently used in the papermaking industry during the last decade as neutral sizing agent which has replaced the acidic sizing agent (Gum Rosin) greatly. Advantages: Compare to Acidic sizing agent (Gum Rosin), The Neutral / Alkaline Sizing Agent (AKD) is a chemical treatment that reduces machine breakdown and water recycling difficulties. 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 amount of AKD particles per unit volume through effective dispersion, resulting in obvious improvement of sizing effects in the range of pH 6.5~9.0.
 Application：
       AKD wax does not contain poisonous chemicals like toluene and so on owing to it is produced without impregnate. It is specially used in process of packaging paper for liquid food. It is easy for AKD wax to be emulsified. It can melt at ****0℃. Usually we choose C-starch or cation polymer as emulsifying agent. It can be reduced to particles with uniform charge and be dispersed throughout a fluid by valve homogenizer. During melting process, The temperature of meltage should be strictly controlled. If the temperature is exceed requisite value, The sizing function and stability of AKD emulsion will be affected. As same time, The pressure of the valve homogenizer should be kept stable in requisite value, because the process of the valve homogenizer will directly affect quality of AKD emulsion
