Viscosity 6000 to 10000cps Dry Strength Agent pH Value 3 to 6 Storage Stability Less Than 6 Months Ideal for Paper Reinforcement Applications

Product Description:

The D7 series dry strength agent is an innovative product developed by our company in response to the substandard quality of domestic waste paper and the growing demands from customers for enhanced paper quality. This advanced agent is designed to address these challenges effectively.

One of the key features of this product is its ability to rapidly adsorb onto pulp fibers. Through ionic interactions, it forms a complex network of ionic bonds that significantly enhance the bonding strength between fibers. This improvement at the microscopic level translates to better cohesion within the paper structure.

Moreover, the D7 series dry strength agent contributes to the enhancement of several important physical properties of paper. It effectively increases tear resistance, folding endurance, tensile strength, and ring crush strength, among other durability indicators. These improvements ensure that the paper performs better during manufacturing and in its end-use applications.

This versatile product is extensively utilized in the production of various types of paper, including boxboard, tube paper, cardboard, specialty papers, and cultural papers. Its broad applicability makes it a valuable solution for the papermaking industry.

Applications:

The point at which the application occurs is crucial for achieving optimal performance and ensuring proper retention. Selecting the right application stage can significantly impact the effectiveness of the chemical additives used during the papermaking process.

Wet End Addition (Most Common): The dry strength additives (DSA) are typically introduced to the thin stock, which is a diluted fiber slurry, before it reaches the headbox and forming wire. This method allows the DSAs to integrate thoroughly with the fibers as the paper structure begins to form.

Location: Generally, DSAs are added after the fan pump. This placement guarantees good mixing while minimizing the time the additives spend exposed to shear forces that could degrade their performance. The short residence time helps preserve the functionality of the DSAs.

Charge Interaction: Fibers in water usually carry a negative charge. Therefore, cationic DSAs, such as cationic starch and cationic polyacrylamide (PAM), are most commonly used at the wet end. These positively charged additives are electrostatically attracted to the negatively charged fibers, enhancing retention and bonding within the paper matrix.

Size Press or Film Press: In some cases, DSAs can be applied on the surface of a partially dried paper sheet. This application method is particularly effective for improving surface strength, reducing dusting, and enhancing printability, contributing to the overall quality of the finished product.
