AKD Surface Sizing Agent,
Surface Sizing Paper Making Chemicals
Paper making chemical white emulsion AKD surface sizing agent for the water resistance
AKD surface sizing agent
The purpose of surface sizing is usually to prevent liquid penetration, obtain better surface properties and improve the physical properties of the paper sheet (such as surface strength and internal binding force), which is an effective means to improve the performance of the base paper. Through the surface sizing machine, the emulsified glue is continuously, evenly and stably applied to the surface of the paper, and after a series of physical effects such as infiltration, penetration and extrusion, an extremely thin waterproof layer is formed on the surface of the paper , Greatly improve the paper's water absorption resistance, and at the same time improve the bonding strength between fibers and the paper's tightness under the action of glue, thereby improving the paper's horizontal ring pressure index, longitudinal splitting length and other technical indicators.

3. Product description:
Sizing agent is a paper surface treatment agent, which can provide different paper types to the resistance of different liquids, its low viscosity characteristics provide this product is easy to pump properties, general standard low shear metering pump is suitable.
Based on the high-efficiency characteristics of this product, the selection of the general addition point should be as close as possible to the top rubber roller. The use of starch or the suction end of the outlet pump is the recommended addition point.
The surface sizing agent is compatible with most starch types and other additives on the surface of the rubber roller used. Other additives include: OBA, defoamer, etc. However, the compatibility test is recommended to be evaluated before the formal test.
The surface sizing agent has a shelf life of 60 days under normal environment. If the storage environment temperature is too high or the storage time is too long, it will reduce the efficiency of the product. The glass fiber material can be used in the storage tank or conveying pipeline .
Fourth, product application:
The recommended addition amount of surface sizing agent is generally 2-4kg/t paper. The addition point is the suction end of starch using barrel or outlet pump. Surface sizing can be used in the starch bucket at the same time as other additives, but it cannot be pre-mixed. The pH of the gumming roller starch should be controlled above 7.0 to maintain the treatment effect to ensure the use effect.
