Retention aid in papermaking (PEO)
Poly Ethylene Oxide (PEO) is linear and high molechar polymer. It has good water-solubility, lubricity, thermoplastic hot melt and reducing rent performance, its water solution has high viscosity and superior stringiness, it is used widely in papermaking industry as pulp dispersant which use in papermaking. Short fiber paper which containing filling and paints in the process of papermaking can loss partial filling (paints) and short fiber paper with the water. If in the process of papermaking, add a kind or several kinds composition with PEO which can form associating first, then add tiny PEO (0.03-0.05kg PEO/Ton pulp), shall take back filling (paints) above 90%, recovers short fiber above 85%, can reduce the consumption of raw material, increases output. The addition of PEO makes pulp’s fiber into order, sequentially strengthen the paper’s pull, also can improve the travel speed. At the same time it also in favor of water paper’s drainage, reduces resin type of organics’ depositing in paper machine, also can accelerate the recycling of water usage and wastewater carbon emission reduction in papermaking.
