3. Product functions
3.1 To increase the retention rate of paper fines and fillers dramatically so as to decrease the pulp consuming qty.
3.2 To decrease the concentration of whitewater,wastage of fines&fillers and the whitewater pollution.
3.3To increase the permeability properties of pulp and the wet strength of paper.To increase the production speed of paper-making machines so as to increase the production.
3.4Without any pungent odor.And has better fluidity under lower temperature.
4. Dosage&Usage tips
4.1 Dosage:around 0.3kg to 0.8 kg per mt paper(adjust as per different pulps and production processes)
4.2To add JH-8501 evenly and slowly into dilution tank with ready water. And add additional water till requested qty(the dilution concentration of JH-8501 is usually 1‰-3‰).
4.3 To stir the diluted concentration for around 20 to 30 minutes before entering into paper-making system via flow pump.
5. Product function mechanism during the paper-making process
5.1 To neutralize the paper surface charge.The pulp and filler are of negative charges and the charges can be neutralized and decreased by adding into JH-8501so as to form micro-floc when the potential towards zero.
5.2 To be inlaying effect.The electrostatic of positive charge on JH-8501 surface can attract pulps and fillers whose surface is of negative charges.
5.3 To be bridging effect.Higher molecular weight and longer enough molecular chain will result in bridging between fines and fillers so as to form micro-floc.
5.4The micro-floc of fines and fillers will decrease the porous structure blockages of wet paper layers and increase the permeability properties of papers.
6. Package,Storage&Shelf life time:
The package is 200 Liters plastic drum or 1000 Liters IBC drums or as per clients’ requests.
It should be stored between 5℃-30℃.The shelf life time is 6 months.
7. Notes:
To wave the JH-8501 before dilution and the diluted liquid can be stored 3 days at most.
Smart and Responsive Polymers: Developing aids that change behavior in response to specific process conditions (e.g., pH, temperature, shear).
Enhanced Bio-Based Aids: Further research into modifying natural polymers (like guar gum, starch, chitosan) for higher performance and broader application, improving sustainability .
Multi-Functional Additives: Single additives designed to provide a combination of retention, strengthening, sizing, and drainage benefits more effectively.
Precision Control and Monitoring: Integration with online sensors and automated control systems for real-time dosage adjustment based on instant retention and ash measurements.
Tailored Solutions for Recycled Fiber: As recycled fiber use increases, developing systems even more robust to high levels of contaminants and ionic interference will be crucial .
Selecting the right retention aid is a strategic decision that significantly impacts paper quality, production efficiency, cost, and environmental footprint. The choice depends heavily on the specific furnish composition, paper grade, machine conditions, and desired outcomes.
For high-value grades where strength is paramount (e.g., packaging), multi-component cationic resins or systems incorporating cationic PVA offer significant benefits.
For applications requiring natural products or clean combustion (e.g., cigarette paper, food packaging), cationic guar gum is an excellent choice.
For general-purpose cost-effective retention across many grades, CPAM remains a versatile option, often used as a component in more complex systems.
