  • Aluminum powder blasting slurry sensitizer
    Patent number: 4348242
    Abstract: An improved water dispersible aluminum powder composition containing from 0.1% to less than 5% of a polyvinylpyrrolidone resin, and processes for its preparation are disclosed. This composition has the advantages that, in comparison to known compositions containing higher levels of polyvinylpyrrolidone, it can be more completely separated from hydrocarbons, and, when used as a water based slurry blasting agent sensitizer is effective in smaller diameter bore holes.
    Type: Grant
    Filed: November 27, 1979
    Date of Patent: September 7, 1982
    Assignee: Alcan Research and Development Limited
    Inventors: John H. O'Dette, Stanton E. Jack
  • Aluminum powder blasting slurry sensitizer
    Patent number: 4274894
    Abstract: Aluminum powder compositions, and methods for their preparation, comprising fine particle size aluminum powder, a polyvinylpyrrolidone resin in an amount of 5% to 20%, based on the aluminum, and either a hydrocarbon or a polar liquid medium in an amount of 30% to 50%, based on the aluminum, are described. These compositions find use as sensitizers in slurry-type blasting agents. Compared to known compositions, they are both dust free and substantially non-reactive, on storage, toward the aqueous milieu of such a slurry.

  • Product and process for non-dusting aluminum grain
    Patent number: 4207099
    Abstract: A new aluminum grain, together with a process for its preparation, suitable for use in blasting agents is described. The grain, obtained by shearing sheet material of various types with a modified cutter comprises largely flat particles with jagged edges, and contains minimal quantities both of oversize and undersize particles.
