    摘要： The invention relates to a process for making paper or paper board comprising forming a cellulosic suspension, flocculating the suspension, draining the suspension on a device to form a sheet and then drying the sheet, wherein the suspension is flocculated using a formation improving 3-component flocculation system comprising a) a linear cationic or ampoteric co-polymer of: i) acrylamide, and ii) a substance with formula (I) with a halide as counter-ion; b) at least one water soluble component chosen from the group of anionic polyacrylamide, non-ionic polyacrylamide and polyethyleneoxide; and c) inorganic microparticles, whereby the flocculation system does not contain a wafer-dispersible or branched anionic organic polymer. The invention also relates to use of the flocculation/retention system in the manufacture of paper or paper board, and to paper and paper board thus produced.

    摘要： "PROCESS FOR OBTAINING MAGNETIC CELLULOSE PAPER AND THE RESPECTIVE PRODUCT" refers to a method for the production of magnetic paper and the respective paper, belonging to the field of paper products; in its usual form, the magnetic sheets, known as magnetic paper, are composed by magnetic blankets covered with cellulose sheets, and this setting results in a sheet of high thickness and high cost, in order to solve these disadvantages, the object of the present patent application was developed, referring to a magnetic paper, which differentiates itself from others because it has magnetic particles in its fibers, and also in its production process, more specifically in the magnetic cellulose sheet, in presentation is comprised by paper sheet (17) which can be of varied densities and has magnetized (11) ferrous-magnetic granules or particles of magnets inserted between its cellulose fibers during the manufacturing process of the sheet.
