Colorless Transparent Liquid Dry Strength Resin with pH Value 3-6 Enhances Paper Dry Strength and Fiber Bonding Efficiency

Product Description:

The D7 series dry strength agent is an innovative product developed by our company in response to the low quality of domestic waste paper and the growing demands from customers for better paper quality. This advanced agent is designed to enhance the overall strength and durability of paper products.

Once applied, the D7 dry strength agent rapidly adsorbs onto pulp fibers. Through ionic interactions, it forms a complex network of ionic bonds, which significantly enhances the bonding strength between the fibers. This strong fiber network results in improved structural integrity of the paper.

In addition to strengthening the fiber bonds, the product effectively boosts several key physical properties of paper, including tear resistance, folding endurance, tensile strength, and ring crush strength. These improvements ensure that the final paper product performs well under various mechanical stresses.

The D7 series dry strength agent is widely utilized in the production of various types of paper, such as boxboard, tube paper, cardboard, specialty papers, and cultural papers. Its versatility and performance make it an ideal choice for papermaking applications that require enhanced paper quality.

Applications:

The point at which the application is made plays a crucial role in achieving optimal performance and retention of the product. Proper timing and location of the additive introduction can significantly influence the overall efficiency of the process.

One of the most common methods is the Wet End Addition, where the Dry Strength Additive (DSA) is introduced to the thin stock, which is essentially a diluted fiber slurry. This occurs prior to the headbox and the forming wire, ensuring that the additive is well incorporated into the fiber suspension.

Typically, the DSA is added right after the fan pump. This position is chosen because it allows excellent mixing while keeping the residence time short enough to prevent degradation caused by shear forces, thereby preserving the additive’s effectiveness.

Regarding charge interaction, since most fibers in water carry a negative charge, cationic DSAs such as cationic starch and cationic polyacrylamide (PAM) are favored at the wet end. Their positive charge enables them to be electrostatically attracted to the negatively charged fibers, enhancing retention during the forming process.

Additionally, DSAs can be applied using a Size Press or Film Press on the surface of the pre-dried sheet. This technique is particularly beneficial for boosting surface strength, minimizing dusting, and improving printability, making it a valuable option for enhancing the quality of the final product.
