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.

Embodiment

[0020] Example: such as figure 1 As shown, a method of producing molded door panels with miscellaneous wood, including chipping, sieving, washing, hot grinding, drying, paving, pre-pressing, hot-pressing and post-treatment after specification sawing, the main process is :

[0021] 1. Preparation means chipping and sorting:

[0022] 2. The small-diameter wood, branches and wood processing residues are chipped and screened (the small ones are sent to the thermal energy center as fuel, and the oversized wood chips are crushed by the re-crusher and incorporated into qualified wood chips, screened Use magnets before and after to remove iron).

[0023] The wood chips that meet the specifications are washed to remove stones, mud, sand, metal and other sundries, and then sent to the pre-steaming bin. The wood chips are heated and cooked by steam in the pre-heating bin. Enter the vertical cooker for cooking and softening treatment. After the softened wood chips are added with paraf...

Abstract

The invention discloses a method for producing molded door panels with miscellaneous wood. , tree branches and wood processing residues are processed by chipping and screening. After the wood chips are washed with water to remove stones, mud, sand, metal and other sundries, they are sent to the cooking tank for cooking, and then the wood chips are mechanically ground into fibers in a heat mill under high temperature and high pressure conditions. Add paraffin wax to the wood chips before hot grinding, and add adhesive, curing agent and buffer to the fibers after hot grinding; the dried fibers are sorted by cyclone to obtain qualified fibers; the qualified fibers are pre-pressed into slabs, and then the slabs are heated Thermoforming is completed in the press to produce fiberboard. The fiberboard produced by the invention can meet the individual needs of different consumers for furniture, rationally utilize the effective space, and have a more humanized design; the furniture designed by the fiberboard can be assembled and disassembled, reducing the inventory backlog 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...
