Abstract:
TEXTURING THE SURFACE OF THE SHEET MATERIAL-WAX-TISSUE LAMINATE BY ADDING A LUBRICANT TO THE WAX WHICH IS COATED ON THE SHEET MATERIAL PRIOR TO LAMINAING WITH THE TISSUE, THE LUBRICAWNT, WHICH IS PREFERABLY LIQUID AT ROOM TEMPERATURE, MIGRATES THROUGH THE TISSUE LAYER TO THE SURFACE OF THE LAYER OF SHEET MATERIAL WHICH BECOMES ADJACENT THERETO WHEN THE LAMINATE IS COILED.
Abstract:
A metal working lubricant which can be used for drawing and ironing of sheet stock as well as used as a mechanical lubricant such as a hydraulic oil in the associated metal working equipment comprises a combination of a carboxylic acid; a film forming and wetting agent which comprises a long chain mono or diester of a carboxylic acid; a non-ionic, non-metallic ester or ether emulsifier; and a mineral oil. The viscosity of the lubricant should be at least 250 Saybolt seconds (SSU) and the lubricant, when emulsified, should preferably have an acidic pH.
Abstract:
Use of a vertical separating tank-hydraulic leg arrangement to continuously separate the light and heavy phases of a gravityseparable three-phase dispersion containing third-phase contaminants and to flush the contaminants at intervals.
