Abstract: The impregnating or extracting treatments of resin-containing wood substrate using a resin-soluble supercritical fluid as delivering or extractive solvent medium problems due to exudation of resin from the wood substrate at pressure release necessary before the termination of the treatment are avoided or reduced by displacing at least partially the supercritical fluid by a fluid of relatively low solubility in the resin before pressure release down to atmospheric pressure is terminated. Thereby the total process time can be substantially reduced.

Abstract: The surfaces of particulate polymers are tackified by contacting them with a liquid that is normally a gas at room temperature. The gas is at or near its supercritical phase (i.e., in "supercritical range") and tackified surfaces of the polymers are modified by variously adhering solids to their surfaces, by altering their surface geometry, or by increasing their size by controlled agglomeration.

Abstract: The present invention is directed to methods for the spray application of additive compositions containing additive materials in the manufacture of sheet material products, such as paper products, textile products, and flexible sheet products by using compressed fluids, such as carbon dioxide and ethane, as a spraying medium. Additive compositions with high viscosity and which are substantially free of water and/or volatile solvent can be applied to sheet materials. Water-borne additive compositions with reduced water content can also be applied to sheet materials. One preferred spray method uses a decompressive spray of the compressed fluid which produces a uniform spray pattern and a narrow droplet size distribution that can improve application efficiency and quality when additive compositions are applied during the spraying step to rapidly conveyed sheet materials.

Abstract: Solid films are deposited, or fine powders formed, by dissolving a solid material into a supercritical fluid solution at an elevated pressure and then rapidly expanding the solution through a short orifice into a region of relatively low pressure. This produces a molecular spray which is directed against a substrate to deposit a solid thin film thereon, or discharged into a collection chamber to collect a fine powder. Upon expansion and supersonic interaction with background gases in the low pressure region, any clusters of solvent are broken up and the solvent is vaporized and pumped away. Solute concentration in the solution is varied primarily by varying solution pressure to determine, together with flow rate, the rate of deposition and to control in part whether a film or podwer is produced and the granularity of each. Solvent clustering and solute nucleation are controlled by manipulating the rate of expansion of the solution and the pressure of the lower pressure region. Solution and low pressure region temperatures are also controlled.
