Process for obtaining magnetic cellulose paper and the respective product

“Process For Obtaining Magnetic Cellulose Paper And The Respective Product” refers to a method for the production of magnetic paper and the respective paper, and the major disadvantage of the magnetic papers existing in the market till present lies in its high production cost, besides the relatively high thickness resulting from the structure of the magnetic sheet, placed between cellulose papers;

• in order to solve these disadvantages, the object of the present patent application was developed, denominated as method for obtaining magnetic cellulose paper (1), characterized by comprising the following stages:
• initially leave the post-use papers (2) soaked for 24 hours in a container (3), making sure they are all covered with water;
• then pour the cellulose pulp (4) obtained into a mixer (5) and carefully blend;
• pour the resulting mixture (6) into a container (7);
• dip the mold (8) in the container (7) until it is covered by the mixture (6);
• carefully remove the mold (8) from the container and smoothen the paste or mixture with a spatula (9) or spoon;
• once the paste or mixture (6) is conveniently placed on the mold (8), put the said mold (8) on a flat, smooth and leveled surface;
• then, place a neodymium plate magnet (10) on the mold (8);
• sprinkle granules of ferromagnetic material (11) over the mold (8), uniformly covering the entire surface of the mixture (6), the ferromagnetic granules (11) can be obtained by scraping a metallic material (12), such as a nail or similar item, with the use of a file (13);
• then, place the flattened mixture (14) between two sheets of newspaper (15) (to aid in the absorption of water) and then press this arrangement with two wooden boards (16);
• the sheet of paper (17) obtained after drying is placed between two metallic cubes (18) and this set is placed in a spool (19) made of electrical wire;
• then, connect the ends of the spool's wire to a direct current source (20), to create a magnetic field inside it in order to magnetize the metallic particles embedded in the cellulose paper;
• after magnetizing, the magnetic cellulose paper is ready.
