Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of plate processing, and in particular relates to an improved saw blade which can solve the problem that the edge of a plate is easy to become blurred. Background Art
[0002] Fiberboard is a man-made board made by applying adhesive to wood fibers after high-temperature cooking and high-speed grinding, and then gluing them together under heat and pressure. The key processes in fiberboard production are fiber preparation, gluing system, hot pressing, etc. The role of hot pressing is to quickly solidify the glue. The existing formaldehyde-free high-density fiberboard produced by pure MDI glue has high density and strong hardness. Therefore, when sawing, the requirements for saw blades are relatively high, and the quality requirements for boards after sawing are also higher. The boards produced by MDI glue have strong hardness. The teeth of existing saw blades are usually stepped flat teeth, with a back angle of 11°, left and right bevel teeth of 11°, and a blade tooth length of 6mm. When the saw blade cuts the board, the service life will be shortened, and the edges of the board will easily become blurred during sawing. Utility Model Content
