Anionic Corrugated Box Reinforcing Agent
Paper Reinforcing Agent is a new kind type, which are the latest research achievements of our company. 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.
Product performance characteristics:
• Excellent solubility, longer product warranty period.
• Improve the physical strength of paper, improve the water filtration performance and retention performance of the slurry
• Reduce the generation of system deposits, improve paper machine operation efficiency and product quality
• Reduce the amount of other wet-end chemicals such as dry strength agents, retention and filter aids, and improve the efficiency of wet-end chemicals
• High content of active ingredients
• Controllable foam
3, How to use it
Dosing point: the dosing point is generally at the entrance of the mixing tank. The appropriate dosing point should be selected according to the properties of the slurry and the characteristics of the production process. The basic requirement is to ensure the PAM has sufficient reaction time with the fibers in the slurry, and before the addition point of dry strength agent.
Dosage: The dosage of PAM should be determined according to the actual situation. Experience on wrapping paper general polynection ® The dosage of fs9610 ranged from 0.06% to 0.6%, and the dosage of special paperboard could reach 1.0% to 2.0%.
Dosing method: double tank batch dissolving device was used to dissolve The PAM powder is dissolved into 2.0-5.0% storage water solution;, It is suggested that the water at 15-30 ℃ should be used to dissolve the drug, and the continuous stirring time is about 30-45 minutes after adding the drug to the water. Then, the storage solution is diluted online by 5 ~ 10 times of water with a metering pump and added into the slurry. It is suggested that the concentration of the slurry should be 1.0-2.0%. It is required to use volumetric dosing pump, and screw pump is generally used to transfer or add the aqueous solution of the drug, so as to avoid the destruction of polymer chain by mechanical shear force.
Application notice: The PAM should be used as soon as possible after dissolving, and the storage time should not exceed 6 hours; It is suggested to use clean water for dissolution. If the acid / alkaline ratio of dissolution water is too high, the hardness of water is high, the content of SS is high, the COD is high, the residual chlorine is high, and the water temperature is too high, the dissolution and use effect of the product will be affected; If it is dissolved manually, the powder particles will be evenly scattered in the water when dissolved, and it is easy to cause caking if the feeding is too fast.
Material selection of dosing system: it is stored in glass, stainless steel, plastic or epoxy resin containers, and iron, copper or aluminum containers are not allowed.
