Soluble In Cold Water Dry Strength Agent Cationic Composition Improves Fiber Bonding And Increases Paper Sheet Durability

Product Description:

The D7 series dry strength agent is an innovative product developed by our company in response to the poor quality of domestic waste paper and the growing demand from customers for higher paper quality. This advanced agent is designed to enhance the overall performance of paper products by addressing these challenges effectively.

Once applied, the D7 dry strength agent quickly adsorbs onto pulp fibers. Through the combination of ions, it forms a complex network of ionic bonds that significantly strengthens the adhesion between fibers. This improved bonding results in enhanced paper strength and durability.

In addition to reinforcing fiber bonds, the D7 series product greatly enhances several physical properties of paper, including tear resistance, folding endurance, tensile strength, and ring crush resistance. These improvements ensure that the final paper products are more robust and reliable.

This versatile dry strength agent is extensively used in the manufacturing of various types of paper such as boxboard, tube paper, cardboard, specialty paper, and cultural paper. Its broad applicability makes it a valuable solution for producing high-quality paper products across different sectors.

Applications:

The point at which the application is made plays a crucial role in achieving optimal performance and retention of the additive. Choosing the appropriate location ensures that the desired effects are maximized during the papermaking process.

One of the most common methods is the Wet End Addition. In this approach, the Dry Strength Additive (DSA) is introduced into the thin stock, which is the diluted fiber slurry, before it reaches the headbox and the forming wire. This step is typically performed after the fan pump to allow proper mixing of the additive with the fibers. However, the residence time must be kept short enough to prevent degradation due to shear forces during the process.

The charge interaction between the fibers and the DSAs is a key consideration. Since most fibers carry a negative charge in water, cationic DSAs, such as cationic starch and cationic polyacrylamide (PAM), are frequently used at the wet end. These positively charged additives are electrostatically attracted to the fibers, enhancing retention and improving the bonding within the paper matrix.

Another application method involves the Size Press or Film Press, where certain DSAs are applied onto the surface of the pre-dried paper sheet. This technique is particularly effective for enhancing surface strength, reducing dusting issues, and improving the printability of the finished paper product.
