Paper Retention Aid

Fillers, fines, fibers, and minerals could be selectively retained in the sheet by optimizing retention. This approach will increase the paper quality and improving productivity. Well controlled retention will also improve dewatering and the retention of other papermaking chemicals. SDB paper retention aid, which is a highly effective retention agent for paper making, is designed to improve the water holding capacity, drainage, and operation of machines.Our retention aid could either be used as a single retention system or be used in combination with mineral or organic coagulants.

SDB paper retention aid characters:

• High retention capacity.
• Good filtration speed.
• Reduce steam consumption and breakdowns in wet parts.

Sludge Dewatering

Sludge treatment is an important part of the water treatment in paper industry which can be performed on filter, screw and belt presses and also centrifuges. For dewatering the target is to achieve maximum water releasement while getting acceptable rates of solids throughput. Technically there is an optimum condition for each unit where desired solid throughput and cake moisture are met. Also, the quality of water discharging from the unit is needed to be taken into account. SDB coagulants used in water treatment are an effective sedimentation and centrifugation reagent in the treatment of partially digested or activated or chemically treated waste sludge from the paper.

Dispersant Agent

SDB dispersant agent could help the solid material dispersed in a liquid easily and stably. Our products could deflocculate solids and thus significantly reduce the viscosity of dispersion and the solid loading could be increased accordingly. SDB dispersant agent, with shorter dissolving time, has been widely used in the papermaking of tissues, household papers writing papers and napkins.

SDB dispersant agent characters:

• Short dissolving time.
• Evenly disperses pulp fiber with good forming effects.
• Enhance dry-wet degree and tension.

Paper Reinforcing Agent

Paper Reinforcing Agent is a new kind type, which is the latest research achievements of SDB. The product has cationic and zwitterionic ions, and is choosed according to customer's paper type manufactured and physical strength index requirement.

Throughout the PH value, the product is ionizing completely,which can directly adsorb onto fiber pulp.The amide group and the hydroxyl group combine to form a covalent bond which efficiently improve the bond strength between fiber.

Also, the product is highly efficient fiber dispersing agent, enabling a more even distribution of pulp fibers in the uniform, and can improve the paper formation.

In the process of combination with tiny fiber, improve fiber retention rate.Paper Reinforcing Agent not only enlarge interfiber bond region, but also increase the number of hydrogen boning junction and strength- site, so that it effectively improve the physical indicators of the paper, such as the paper dry strength, fracture length, durability stiffness,pop strength, pressive strength and other indicators.
