A method for coating and curing a material on a product having a plurality of edges and faces. More specifically, disclosed is an efficient method for coating and curing engineered wood products (EWP) in general, and the edges of EWP in particular.

Efficient infrared absorption system for edge sealing medium density fiberboard (MDF) and other engineered wood laminates using powder and liquid coatings

The present invention has to do with an efficient system for coating and caring engineered wood products (EWP) in general, and the edges of EWPs in particular. An efficient system for coating and curing coatings is provided.

The present invention has to do with an apparatus for generating a three dimension heating gradient field for curing powder coated wood products. The three dimension heating gradient field is generated with catalytic heater panels having independently adjustable angles and adjustable heat outputs.

Apparatus and system for three dimensional infrared gradient heating for curing powder coatings on porous wood products

An improved apparatus is provided for curing powdered coatings on the face of porous wood products, such as medium density fiberboard (MDF), wherein a pair of inclined infrared catalytic heaters are used to apply heat directly onto the side edges of the board. In addition, catalytic heaters that are normally used to heat and cure the face surface of the board are moved father back to reduce their effectiveness and to limit out-gassing of entrapped air from the inner low density core of the board. This arrangement also allows the coating to cure at the side edges of the board at approximately the same rate as the face of the board, promoting a more uniform curing of the powder coating.

Apparatus for heating and curing powder coatings on porous wood products

The invention provides a method of preheating a catalyst in a catalytic heater comprising the steps of preparing a gaseous mixture of hydrogen and nitrogen in a volume ratio of between about 95% hydrogen to about 5% nitrogen and about 5% hydrogen to about 95% nitrogen and dispersing the gaseous mixture into contact with the catalyst for a period of time sufficient to raise the temperature of the catalyst to a level that will promote the flameless oxidation of a fuel gas in the presence of the catalyst.

Method of preheating catalytic heater

A gas catalytic heater having an improved temperature distribution is disclosed which includes a body having an open end in which is disposed a porous catalytically active layer containing a catalyst such as platinum metal. A sealed plenum chamber is disposed below the catalytically active layer and has a gas-permeable wall portion facing toward the active layer and a gas inlet orifice for introducing a fuel gas into the chamber. The gas-permeable wall portion may comprise a perforated metal plate having a plurality of tiny apertures the total open area of which is significantly less than that provided by perforated plates used in catalytic heaters of the prior art.
