The present invention discloses a formaldehyde-reducing process in the production process of veneered strip-glued board and its equipment. Said equipment mainly includes ventilating ducts and fan, and its formaldehyde-reducing process includes the following steps: spaced stacking the adhesive-coated mechanically-matched or hot-pressed board blanks, making the air inlets of ventilating ducts be positioned at two sides of board blank stack respectively, making the air outlets of ventilating ducts be positioned in the exterior of processing field, under the action of the fan a negative pressure action is formed around the board blank stack, so that the peripheral air of the board blank stack can be led out to the exterior of processing field so as to quickly discharge out free formaldehyde produced in the adhesive-coating process, and effectively prevent the free formaldehyde from being absorbed by board core and finished product board and can reduce formaldehyde content in the product obviously. |
