To provide a board material processing composition allowing for production of a board material laminate that is non-combustible and is excellent in adhesion performance. In order to solve this problem, a board material processing composition inhibiting combustion of a board material due to heating, comprises: a carbonization promotion component, being inorganic, promoting carbonization of an organic component within the board material at the heating; a chain inhibition component, being inorganic, inhibiting a reaction chain to a neighboring component due to a product of endothermic decomposition generated at the heating; and binder particles, being inorganic and hydrophobic, bonding the organic component within the board material to the carbonization promotion component and the chain inhibition component, wherein the carbonization promotion component includes boric acid, the chain inhibition component includes ammonium dihydrogen phosphate, and the binder particles include silica sand.

A veneer panel may include a face veneer, a first inner layer bonded to the face veneer, a second inner layer bonded to the first inner layer, and a thermally conductive layer bonded to the second inner layer. The first inner layer and the second inner layer are treated with a flame retardant. The first inner layer is disposed between the face veneer and the second inner layer, and the second inner layer is disposed between the first inner layer and the thermally conductive layer.

A method of producing a core board suitable for a coated multi-ply wood panel, as well as a coated multi-ply wood panel. The method comprises the steps of providing a wood based material in the form of a plurality of layers and an adhesive suitable for bonding the layers to each other; the layers of the wood based material and the adhesive being arranged in alternating order to form a stack, the stack having two opposite faces formed by a wood based layer. On at least one of the faces of the stack there is further provided adhesive and fibrillated fibers to form a modified stack which is pressed by one-step pressing to form a multi-ply wood panel having a facing coated with a layer of fibrillated fibers. The even and smooth surface of the core panel makes it particular suitable for coating with, e.g., glossy films.

A fan blade has a body made of plywood/fiberboard and having two opposite ends, at least one assembling hole disposed at one of the two opposite ends of the body, and a tip disposed at the other one of the two opposite ends of the body and being flat or curved. A manufacturing method for the fan blade has four steps. Step 1: manufacturing plywood panels/fiberboards by carpentry machining. Step 2: adhering paper/veneers/melamine paper to the plywood panels/fiberboards. Cutting the plywood panels/fiberboards into shape to form the body. Step 3: cleaning debris on the body. Step 4: coating a pattern being consistent with patterns of the upper and bottom surfaces of the body on the circumferential edge of the body by heat pressing. With the pattern printed on the circumferential edge of the body, the fan blade is consistent in appearance.
