  Product name: Neutral AKD sizing agent   Neutral AKD compound glue (AKD Sizing Agent)   AKD(Alkyl Ketene Dimer) can be used in writing paper, two-side offset paper, electrostatic copy paper, coated paper, wrapping paper, etc.   I. Technical indexes   Chemical name:Alkylketene dimer CAS NO.144245-85-2   EINECS No.: 284-932-5 MF:R-CH=C-O-C-CH-R    Appearance: Milk white or yellowish emulsion Solid content: 15±0.5% (or upon customer's request) Ion type: Cationic PH value: 2-5 Viscosity: ≤30mPa.S(25°C) shelf life: 3 months (5-30°C)    II. Notes   1. PH should be 6.8~8.5 if used in chemical pulp. 2. To determine optimal proportion, adding mode and place in accordance with specific conditions. 3. Guarantee that the drying cylinder temperature of at least one paper machine soluble be higher than 95°C. 4. AKD emulsion should be kept at low temperature, shelf life is 60 days at 20°C.     III. Packing and storage   200kg or 1000kg plastic drum, tightly sealed in chambers at room temperature.   V.Attention 1. PH value of the forward mesh headbox is controlled in 6.8 ~ 8.5. If less than 6.8, adding alkali to adjust it.
2, The paper factory 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 °C.
4. The equipment and pipeline should be thoroughly cleaned by change acidic papermaking into mediate alkaline papermaking.
