AKD sizing agent

Capability AKD sizing agent is one of newly-developed products in our company for the purpose of avoiding defects such as slow ripening, easy to be under machine moisture regain, high cost, ect.. Common AKD emulsion using amylum as emulsifier, which cause low retention rate, large dosage, slow ripening. A100 neutral polyester sizing agent adopts a new type of polymer emulsifier that our company developed independently which takes the petroleum resin as main raw material, and is supplemented by other cationic surfactant,. The emulsifier is polymer, high cationic charge density and thus the emulsification has highly efficiency, uniform dispersion, and small particle size. The manufactured AKD sizing agent ripens fast with high efficiency and small dosage. General resistance to water penetration under the machine is up to 60 seconds, The dosage of per ton paper that compared with the ordinary AKD products can be reduced more than 15%. The Main Technical Indicators 1. Appearance: white emulsion 2. PH value: 3-5 3. Solid content: 15% ¡À 0.5% 4. Iconicity: cationic 5. storage period: 3 months (5-30 ¡æ) Direction 1. Within the PH value range of 6 to 8.5, the product is recommended to use calcium carbonate as the filler, which can replace traditional rosin sizing agent and AKD neutral sizing agent. 2. The added amount of per ton absolute dry pulp is 5-10 kg, It¡¯s preferable with metering pump that continuously added into the Mixing tank, high tank or slurry pipeline. 3. Per ton absolute dry pulp adds 200 grams -300 grams of polyacrylamide and the molecular is 6.0 million. The results will be better. Attention 1. PH value of the forward mesh headbox is controlled in 7.0 ~ 8.5. If less than 7.0, adding alkali to adjust it. 2, The mill should select the best ratio, adding locations and adding way according to the specific situation. 3. Make sure that at least one of the paper machine¡¯s drying cylinders temperature do not lower than 95 ¡æ. 4. The equipment and pipeline should be thoroughly cleaned by change acidic papermaking into mediate alkaline papermaking. Packaging and storage Pack it with 200 kg or 1000 kg plastic barrels, sealed and stored at room temperature, stay indoor. 200 kg drum
