PEO for paper industry

Item :

Details :

PEO use in the papermaking industry:
For long stapled dispersant
        In manufacturing bumf, napkin, teabag’s filter paper, handkerchief paper and cardboard, use PEO for long stapled dispersant, can use lower beating degree of pulp, manufacture good evenness of paper sheet, moreover the plasticity and strength of paper is better, and can reduce the cost at the same time.
For filling’s retention agent
        In the manufacturing process, it will have lost a considerable number of filling and fine fibers. If add 0.225-0.05kg high molecular PEO in per dry fiber, so it can reduce the loss of paint, filling and fine fiber obviously, and that also can reduce the resin type of organics’ aggradations on the paper machine. The mixture of polyethylene glycol oxide (5%~95%) and acrylate copolymer (95%~5%) can use to improving the persistence of filling and fine fiber in papermaking. Such as: add 0.328kg mixture which is composed by 25% of polyethylene glycol oxide an 75% of polyacrylamide, the rate of persistence of filling and fine fiber is 88.2%. But add 0.328kg of per dry paper, the rate of persistence of polyacrylamide is only 80%.
For water-soluble adhesive
        In preparing paper (like bumf, towel paper) which wrap on one core rod, we must use a kind of appropriate adhesive to let the header of paper adhibit on the core rode, analogously the end of axile paper must adhibit with the under layer, to avoid loosening when loading and unloading, packing or other operating, in this kind of usage, has used traditional hot melt adhesive, but is has a shortage which will form permanent splicing between paper and core rod, or between the end of shaft of two paper wool, when lift down paper from the shaft, it shall cause the undesirable tearing of paper. Use PEO resin’s aqueous solution and other ingredients to make water-soluble adhesive, when adhesive is drying, it will lose viscosity, so, when lift down paper from the shaft, it never exist the problem of paper tearing.
Paper particular type of paper which containing synthetic fiber and glass fiber’s polyolefin.
        Use PEO for glass fiber of dispersant, mix with organic fiber, fibrin plasm and adhesive, prepare thin paper containing glass fiber, the surface of paper is very smooth. Will mix, fuse and extrude 100 PEO and 25 calcium carbonate, launch extruding 500% in 700 centigrade, from thin film, receive favorable writing nature of substitute paper.
        PEO’s coated paper has higher luster and smooth over the traditional, can use higher amount of coat of paper, using the techniques of PEO coat can improve the quality paper.
