Abstract: A process for applying a thermoplastic coating to a substrate wherein the gases and other volatiles in a boundary layer between the substrate and the coating are evacuated using a high volume, high velocity air stream which traverses the surface of the substrate to be coated (functioning as an air knife) such that, when the coating is applied, gases/volatiles do not disrupt the coating while:the coating cools and solidifies. The effect of the air knife may be enhanced by heating the substrate and/or by applying a solvent to the substrate. The air knife also cools down the boundary layer of the substrate so that, as the thermoplastic coating is applied, this cooled-down and gas-evacuated boundary layer provides a measure of insulation between the coating and any gases/volatiles which have not been evacuated from the substrate.

The first step is pretreating the surface of the non-conductive object to ensure that the surface is suitably cleaned. The second step to apply a sufficient quantity of moisture on the surface of the non-conductive object to facilitate adhesion of a powder coating to the surface. The next step is to spray a polymer coating powder on the moistened surface of the non-conductive object. This spraying step is done immediately following the application of moisture but prior to a complete evaporation of the applied moisture. The fifth step is to evaporate any remaining applied moisture from the non-conductive object prior to curing. The last step is to cure the coating on the surface of the non-conductive object without decomposing the powder and then either cool or allow the non-conductive object to cool naturally.

Abstract: A method for treatment of one or more wood elements by pressurization comprises the steps embedding the wood elements into a pressure medium, of increasing the pressure in the pressure medium, whereby the wood element is compressed by transmitting the pressure via the pressure medium to the wood elements, and of reducing the pressure in the pressure medium, whereby the wood element is relieved. During the treatment, liquid present in the wood elements is driven out therefrom. The pressure medium comprises a plurality of solid bodies with intermediate spaces. The solid bodies transmit the pressure to the wood elements such that a pressure difference arises between the wood elements and said spaces, which pressure difference drives out the liquid. During the relief phase, the wood elements substantially resume their original shape. The method can also be used for introducing impregnating liquid into the wood elements after the liquid expulsion.
