Application Scope

This product is mainly composed of alkyl ketene dimer emulsion. It contains long carbon chain hydrophobic functional groups. It binds with hydroxyl groups on pulp fibers to form stable sizing effect. It endows paper with high water resistance and better glossiness. It is widely applied in cultural paper, packaging paper, specialty paper and pulp molding products.

Usage Method

Add this product into the mixing tank, and mix evenly with pulp before use. Please use up the mixture within 2 hours.

It can also be added continuously online by metering pump. The recommended dosage is 0.4% to 3%. The optimal system pH ranges from 7.0 to 8.5. Filter with an 80-100 mesh screen before use. This step prevents potential paper defects.

FAQ

Q: What are the advantages of AKD Sizing Agent compared with rosin sizing?

A: AKD neutral sizing causes no equipment corrosion. It extends the service life of wire and felt. It improves paper strength. The paper resists yellowing and aging during long storage. It raises filler utilization. The finished paper has better smoothness and printing performance.

Q: What leads to slow curing and insufficient sizing degree of AKD sizing?

A: It is mainly caused by low drying temperature, short drying time, low system pH, excessive filler and unreasonable additive combination. These factors limit the crosslinking of AKD molecules and cause slow curing.

Q: What are the core advantages of AKD sizing?

A: It features low dosage and high retention rate. It realizes fast curing. It provides long-lasting moisture and water resistance. It effectively cuts overall production costs.
