Abstract: A hog fuel board is made by placing a hog fuel mat including an ammonium chloride catalyst with flexible non-sticking layers on outside surfaces between screens in a preheated platen press and pressing the mat to preset stops and for a predetermined time and pressure to cause adhesives naturally present in the hog fuel to disperse throughout the board. The presence of ammonium chloride as a catalyst uniformly distributed through the hog fuel mat significantly lowers the temperature required at the heating press platens to form a board which also has improved properties. There is also described a hog fuel veneer board with a hog fuel mat sandwiched between veneer sheets and a lumber product with a hog fuel coating thereon. These additional products are both formed using the ammonium chloride catalyst to reduce press temperatures and create a product with improved properties, particularly, internal bond strength.

Abstract: A laminated decorative tile particularly for flooring purposes, is made by forming a base layer of granulated cellulosic material in a matrix of fusible plastics, and placing on the base layer a thin decorative layer of cellulosic material with natural holes and recesses therein. After a film of fusible plastic has been applied on the decorative layer the laminate is hot pressed and then immediately cooled in a cold press.

In this embodiment the tile has a smooth wear resisting layer surface but this surface can be provided with a relief pattern such that it conforms to the structure of the decorative layer, if the tile after cooling is heated in a free state, i.e. without press plates.

Abstract: Flameproof and fireproof products are formed from a fire-unstable material coated with a polymeric material which is capable of intumescing beginning at a low temperature and has adhesive qualities in conjunction with the fire-unstable material. Upon the application of heat or flame to the products, the coating material copiously intumesces to form a protective thermal insulating foam barrier which prevents the fire-unstable material from igniting or degrading to the point of evolving flammable gases or losing its dimensional stability. Continued application of heat or flame will cause the foam to char but will not destroy the products for a suprisingly long time. The polymeric coating material comprises the resinous reaction product of phosphoric acid and a reducing sugar with a hardener and containing at least one modifying agent capable of rendering the coating material highly and permanently intumescent at a low initiating temperature even after prolonged storage of the flameproof and fireproof product.
