Method for producing mold-pressing door planks through wood scraps

Abstract

The invention discloses a method for producing mold-pressing door planks through wood scraps. The method comprises processes of chipping, screening, washing, heat grinding, drying, matting, pre-press molding, hot pressing, specification sawing after-treatment and the like. Small-sized timber, branches and wood machining residues are chipped and screened; wood chips are washed to remove impurities such as stone, sands and metals and are then boiled in a boiling cylinder; in a defibrator, the wood chips are heat-grinded into fibers at high temperature and high pressure, and before the heat grinding process, paraffin is added into the wood chips, and after the heat grinding process, adhesives, curing agent and buffer agent are added into fibers; the fibers are dried and then separated through cyclone to obtain qualified fibers; the qualified fibers are molded plank blanks; the plank blanks are hot-pressed in a hot press machine into fiber planks. According to the method for producing the mold-pressing door planks through the wood scraps, the obtained fiber planks can meet the personalized requirements of various consumers on furniture and make reasonable use of effective space and are humanized in design; furniture designed from the fiber planks can be assembled and disassembled to reduce inventory overstocking of different furniture.

Description

technical field [0001] The invention relates to the field of furniture, in particular to a method for producing molded door panels with miscellaneous wood. Background technique [0002] Medium density fiberboard (English name: Medium Density Fiberboard, abbreviated as MDF, referred to as MDF). Medium density fiberboard is made of small-diameter logs, harvesting, processing residues, and non-woody plant fiber raw materials. After slicing, cooking, fiber separation, and drying, urea-formaldehyde resin or other applicable adhesives are applied, and then hot-pressed. A kind of man-made board. [0003] Molded door panel: Under high temperature and high pressure conditions, the thin fiberboard is molded into a decorative panel with concave and convex patterns. The molded door panel is fixed on the door frame after surface coating to form a molded door, which can be used indoors. [0004] Molded door panels: The fiberboard used to produce molded door panels is called fiberboard f...

Problems solved by technology

[0008] The miscellaneous wood fiber is short and hard, and it is not easy to bend. It is produced by the large-scale tree species of Chengdu Plain according to the conventional process requirements. The curved part of the finished product is easy to crack, and the scrap rate is extremely high.
