Soluble In Cold Water Dry Strength Resin for Paper Ensuring Enhanced Paper Strength and Storage Stability Up to 6 Months

Product Description:

The D7 series dry strength agent is an innovative product developed by our company in response to the inferior quality of domestic waste paper and the growing demands from customers for enhanced paper quality. This advanced formulation addresses the challenges faced in paper production by significantly improving the performance characteristics of the final product.

Upon application, the agent rapidly adsorbs onto pulp fibers. It facilitates the formation of a complex ionic network through ion interactions, which effectively strengthens the bonds between fibers. This enhanced fiber bonding translates into superior mechanical properties in the finished paper.

Moreover, the D7 series dry strength agent significantly enhances key physical attributes of paper including tear resistance, folding endurance, tensile strength, and ring crush strength. These improvements ensure that the paper maintains its integrity and durability across various uses.

This versatile product is extensively utilized in the manufacturing of a wide range of paper types such as boxboard, tube paper, cardboard, specialty papers, cultural papers, and more. Its application helps fulfill the stringent quality requirements of multiple papermaking sectors.

Applications:

The application point plays a crucial role in achieving optimal performance and retention of the product.

One of the most common methods is the Wet End Addition. In this process, the Dry Strength Additive (DSA) is introduced into the thin stock, which is a diluted fiber slurry, before it reaches the headbox and the forming wire. Typically, the DSA is added right after the fan pump. This placement ensures thorough mixing while maintaining a short enough residence time to prevent degradation caused by shear forces.

Charge interaction is another important factor to consider. Since the majority of fibers carry a negative charge in water, cationic DSAs such as cationic starch and cationic polyacrylamide (PAM) are most frequently used at the wet end. Their positive charge allows them to be electrostatically attracted to the negatively charged fibers, thereby enhancing retention.

Alternatively, some DSAs can be applied later in the process, specifically at the Size Press or Film Press stage. This application occurs on the surface of the pre-dried sheet and is highly effective in improving surface strength. Additionally, it helps to reduce dusting and enhances the printability of the final product.
