Novel fiberboard manufacturing process

Abstract

The invention discloses a novel fiberboard manufacturing process. The novel fiberboard manufacturing process is characterized in that a fiberboard comprises a middle layer, and the middle layer is externally provided with a surface chemical fiber layer and is a composite layer made of coconut fiber and chemical fiber; the fiberboard manufacturing process comprises the following steps of S1, raw material preparation, S2, raw material storage, S3, primary middle layer raw material mixing, S4, primary middle layer raw material carding, S5, secondary middle layer raw material mixing, S6, secondary middle layer raw material carding, S7, surface-layer chemical fiber raw material preparation, S8, surface-layer chemical fiber net paving, S9, surface-layer chemical fiber needling, S10, semi-finished product synthesis, S11, drying machining, S12, cooling shaping, and S13, finished product completion. According to the novel fiberboard manufacturing process, the natural coconut fiber and the chemical fiber are composited, the produced fiberboard is of a three-layer structure, and the coconut fiber is covered with the chemical fiber, so that the fiberboard is more beautiful, and the toughness of the fiberboard is improved; and fiber on the surface layer is subjected to needling treatment, the strength of the fiberboard is improved, and thus, the fiberboard is not prone to being abraded.

Description

technical field [0001] The invention relates to the technical field of fiberboard processing, in particular to a novel fiberboard manufacturing process. Background technique [0002] Fiberboard, also known as density board, is a wood-based panel made of wood fiber or other vegetable fiber and applied with urea-formaldehyde resin or other suitable adhesives. Adhesives and / or additives may be applied during the manufacturing process. Fiberboard has the advantages of uniform material, small vertical and horizontal strength difference, not easy to crack, etc., and has a wide range of uses. The disadvantage of fiberboard is that there is a texture on the back, resulting in unequal surface areas on both sides of the board. After moisture absorption, the board is warped due to the difference in expansion force; the surface of hard board is hard, difficult to nail, and poor water resistance. Although dry-laid fiberboard avoids some disadvantages, the cost is relatively high. Con...

The disadvantage of fiberboard is that there is a texture on the back, resulting in unequal surface areas on both sides of the board. After moisture absorption, the board is warped and deformed due to the difference in expansion force; the surface of hard board is hard, difficult to nail, and poor water resistance.

Although dry-laid fiberboard avoids some disadvantages, the cost is higher
