Odor control pulp composition
The present technology is directed to fluff pulps with improved odor control as well as methods of making such fluff pulps. A fluff pulp is provided that includes a bleached kraft fiber and a copper ion content from about 0.2 ppm to about 50 ppm by weight of the bleached kraft fiber. The bleached kraft fiber includes a length-weighted average fiber length of at least about 2 mm, a copper number of less than about 7, a carboxyl content of more than about 3.5 meq/100 grams; an ISO brightness of at least 80; and a viscosity from about 2 cps to about 9 cps.
BOARD, METHOD OF MANUFACTURING A BOARD AND A PANEL COMPRISING SUCH BOARD MATERIAL
Boards have a mineral content, including magnesiumoxychloride and/or magnesiumoxysulphate, and may be finished with a DPL laminate decorative layer.
Total heat exchange element paper and total heat exchange element
Total heat exchange element paper having excellent moisture resistance and gas barrier properties, comprising a substrate sheet and a moisture absorbent and colloidal silica both of which are adhered to the substrate sheet, wherein the substrate sheet contains natural pulp which has been beaten to a freeness specified in JIS P 8121-1:2012 of not lower than 80° SR and the colloidal silica is cationic colloidal silica.
Sheet forming binder, container, sheet forming apparatus, sheet forming method, and powder set
A sheet forming binder includes a first powder and a second powder having a larger volume average particle size than the first powder. The proportion of the first powder is 10.0% by mass or more relative to the total mass of the first powder and the second powder.
Laminate pigment with spacing properties and high UV-greying stability
The invention relates to a titanium dioxide particle with high opacity and UV-greying resistance comprising two silica coats and at least one alumina coat, to a method for the obtaining the same, and to the use of said particle in a method for obtaining a decorative paper laminate or a décor foil. The present invention further pertains a decorative paper laminate or a décor foil containing said coated titanium dioxide particle.
Treated titanium dioxide pigment with high magnesium oxide addition, process of making thereof and use thereof in paper manufacture
Process for the surface treatment of a titanium dioxide pigment, characterized in that it comprises the following steps: an aqueous suspension of titanium dioxide pigments is formed, in a first step, a layer of alumina phosphate is precipitated on the surface of the pigment, in a second step, a layer of alumina is precipitated over the first layer of alumina phosphate, and in a third step, a layer of magnesium oxide and alumina is precipitated on the layer of alumina. Also included are titanium dioxide pigments made by the disclosed process and method using said pigments in paper manufacturing.
