摘要： An atomized fluid, such as a mist of water, is applied to a preheated substrate, such as wood, a wood product, paper, or ceramic just prior to or contemporaneously with electrostatically applying a coating powder to the substrate. The atomized fluid is absorbed or adsorbed by the substrate so as to enhance the charge-carrying capacity of the substrate to an extent necessary to promote efficient electrostatic application of the coating powder to the substrate.

摘要： A water soluble dicarboxylic acid or an alkali metal salt thereof acts as a mold release agent for salt pellets when a salt-contacting surface of a roll-type briquetting press is coated with from about 0.02 to about 5 mg/cm.sup.2 of a powder of the acid or alkali metal salt just prior to a charge of salt. The coating is achieved by spraying an air stream entraining the powder onto the press rolls or by spraying a solution of the release agent onto the rolls and evaporating the solvent to leave the powder on the rolls. The acid has from 6 to 10 carbon atoms; adipic acid being preferred. Salt pellets having a layer of the powder on their surface may be used in water softening systems wherein the pellets sit in a brine reservoir and supply salt for the recharging of an ion exchange resin. There is no formation of an unsightly scum on the surface of the brine and on the sides of the reservoir.
