Definitions

  • the present invention relates to a paper sizing process and more specifically to a process for the sizing of paper filled with calcium carbonate.
  • the fiber aqueous suspension is supplemented with a resin sizing agent, normally based on colophony, which is precipitated by means of a precipitating agent.
  • the precipitating agent of most popular and common use is the alumium sulphate which is added to the aqueous suspension of fibers in form of a water solution.
  • the fiber suspension is added with an inert filler, suitable for giving particular properties to the paper.
  • the specification indicated a general range of 5 to 8, and a preferred interval of 5.5 to 7.0.
  • a polyvalent anion for example the anion of a mineral acid such as sulphuric acid.
  • aluminium polychloride and polyhydroxychloride polymers which for instance in. the case of the polyhydroxychlorides have the general formula: wherein 1 is an integer varying between 5 and 15 for instance of the type produced according to the USP No. 3909439.
  • the present invention provides a process for the paper sizing, of the type in which a precipitating agent is added to an aqueous suspension of fibers containing a colophony based resin size, wherein morevoer calcium carbonate or a like substance is used as the paper filler, characterized in that as the precipitating agent there is used a compound selected among aluminium polyhydroxychlorides, having the formula: wherein 0.85 r x ⁇ 6 and aluminium polychlorides having the f ormula wherein 0 ⁇ , the precipitation taking place at a pH of neutral to alkaline.
  • the process according to the invention permits unexpected and unforeseable results to be achived, since it becomes possible to use traditional sizing agents instead of special highly expensive sizing agents, whereby also this sizing operation is brought within a traditional technology, satisfactorily used since long time. There is moreover permitted the recovery and recycling of the coated brokes. Examples are now given illustrating, in a non limiting manner, the results achieved by the present invention.
  • This example discloses a traditional sizing treatment, relating to the production of fine white paper, having a weight of 140 g/sq.m. wherein kaolin is used as the filler.
  • the paper pulp comprises bleached cellulose (90%) and waste paper pulp (10%).
  • This example relates to the production of paper for exercise books having a weight of 65g/sq.m. filled with 5% of calcium carbonate and 5% of kaolin, these percentages being referred to the dry paper.
  • the paper pulp forming the fiber suspension had the following composition:
  • This example relates to the production of 50 g/sq.m paper useful as a support for coated paper.
  • the pulp forming the fiber suspension had the following composition:
  • coated brokes have on the overage a calcium carbonate content of 20-30%.
