【Abstract】 It is determined that Fenugreek residues contain 41% protein, 14% polysaccharide and 1.7% fat, in which much of polysaccharide gum, steroidal saponins and fat have been separated from Fenugreek seeds. The effect of Fenugreek residues increment on the gluing property of urea formaldehyde resin has been studied. Fenugreek residues increment can greatly improve the properties of urea formaldehyde resin. It also can reduce pollution, simplify operation and reduce production cost. The rate of 20%～25% Fenugreek residue increment can add up 15% gluing strength of plywood, and the formaldehyde release reduces to 20 percent compared to urea formaldehyde resin to which no increment adds.更多还原
