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.
