Problems solved by technology

[0004] In addition, in order to increase the production quantity of fiberboard and improve the hot-pressing efficiency of the hot-press machine for fiberboard preparation, many methods have been proposed for preheating the fiber-laid dry fiber rough slab, such as steam spray preheating, microwave heating, ambient air heating, etc. Currently, there are few studies on the direct heating of the core layer.

Abstract

The invention relates to a preparation method and pavement device of a high-strength fiberboard. The pavement device of the high-strength fiberboard is firstly provided and comprises a feeding conveying device and a pavement forming device. The pavement forming device comprises a fiber orientation pavement preheating device and a board blank transport device. The fiber orientation pavement preheating device is arranged between a fiber outlet of the feeding conveying device and the board blank transport device and comprises multiple anode boards and cathode boards and heating components on the two sides. The anode boards and the cathode boards are arranged adjacently and longitudinally at intervals. The preparation method of the high-strength fiberboard comprises the steps of wood chipping, fiber preparing, fiber gluing, fiber pavement, pre-pressing, hot pressing and rough board treatment. Fiber pavement is carried out through the pavement device. According to low-density, medium-density and high-density fiberboards produced through the method and the pavement device, the physical and mechanical property indexes of the boards can be increased under the same production process conditions.

Description

technical field [0001] The invention relates to a preparation method and device of a fiberboard, in particular to a preparation method of a high-strength fiberboard and a paving device thereof. Background technique [0002] Fiberboard is a kind of man-made board made of wood fiber or other plant fiber as the main raw material, prepared by fiber, applied with adhesive, paved and shaped after the fiber is dried, and then hot-pressed. Classified by bulk density, fiberboard can be divided into high-density fiberboard, medium-density fiberboard, and low-density fiberboard. Due to the uniform material of fiberboard, it is widely used in the processing of furniture, floors, wall panels, packaging boxes, ceilings, etc. After more than 40 years of development in the manufacturing technology of fiberboard, the production technology has reached the limit, and the physical and mechanical properties of fiberboard can not be greatly improved, especially in the development of lightweight ...
