  • Patent number: 5955412
    Abstract: A powder blend of 95% Sodium metasilicate anhydrous and 5% sodium lauroyl sarcosinate which is hygroscopic. The mixture is formulated for effective use when 11.25 ounces are dissolved in one gallon of water or diluted up to six gallons of water. The constituent powders are added to the drum at their mixture ratio of 95% sodium metasilicate and 5% sodium lauroyl sarcosinate which will form the blend. The drum is resealed with the processing lid trapping only low moisture air inside. The drum is relocated to the blending machine which rolls and tilts the drum for blending for 30 minutes at 16 rpm, which ensures complete and uniform blending of the 2 constituent powders. Next, the drum is removed from the blending machine, and the processing drum lid is removed in the process room ensuring low moisture exposure. A filling lid is installed which includes an auger feed, and the drum is rotated and placed in the filling stand. An air motor is attached to the auger.
