Embodiment 1

[0019] Embodiment 1, the preparation method of this example comprises the following steps:

[0020] (1) Milling of small-diameter wood: cut small-diameter wood into short pieces of 400mm, and then use the milling machine to radially mill into large pieces of shavings. The size of the shavings is: length 20mm, width 7mm, thickness 0.2 mm;

[0021] (2) Grinding large pieces of shavings: put large pieces of shavings into the toothed disc grinder (such as figure 1 As shown) ground into fibrous fine shavings, the size of the shavings is: length 20mm, width and thickness close to each other, about 0.1 mm;

[0022] (3) Pipeline sizing: Pipeline sizing is used for sizing. The adhesive used is urea-formaldehyde resin adhesive. The concentration of the adhesive is controlled at 40% (conventional formula). 8% of the amount of fine shavings, while adding ammonium chloride of 0.5% of its solid adhesive weight as a curing agent in the adhesive;

[0023] (4) Drying of fibrous fine shavings...

Embodiment 2

[0028] Embodiment two, the preparation method of this example comprises the following steps:

[0029] (1) Milling of small-diameter wood: cut small-diameter wood into short wood sections of 1000mm, and then radially mill them into large pieces of shavings on a milling machine. The size of the shavings is: length 50mm, width 12mm, thickness 0.4 mm;

[0030] (2) Grinding large pieces of shavings: put large pieces of shavings into the toothed disc grinder (such as figure 1 As shown) ground into fibrous fine shavings, the size of the shavings is: length 50mm, width and thickness close to each other, about 0.15 mm;

[0031] (3) Pipeline sizing: use the pipeline sizing method for sizing, the adhesive used is a modified urea-formaldehyde resin adhesive, the concentration of the adhesive is controlled at 45% (conventional formula), and the amount of sizing is the solid weight in the liquid glue. 12% of the amount of dry fibrous fine shavings, while adding 1.0% ammonium chloride of it...

Embodiment 3

[0037] Embodiment three, the preparation method of this example comprises the following steps:

[0038] (1) Milling of small-diameter wood: cut the small-diameter wood into short pieces of 700mm, and then use the milling machine to radially mill them into large pieces of shavings. The size of the shavings is: length 35mm, width 10mm, thickness 0.3 mm;

[0039] (2) Grinding large pieces of shavings: put large pieces of shavings into the toothed disc grinder (such as figure 1 As shown) ground into fibrous fine shavings, the size of the shavings is: length 35mm, width and thickness close to each other, about 0.12 mm;

[0040] (3) Pipeline sizing: Pipeline sizing is used for sizing, the adhesive used is modified urea-formaldehyde resin adhesive, the concentration of the adhesive is controlled at 43% (conventional formula), and the amount of sizing is the solid weight of liquid glue. 10% of the amount of dry fibrous fine shavings, while adding 0.8% ammonium chloride of its solid a...

Abstract

The invention relates to a method for preparing a fiber particle board and aims to provide a method for preparing the fiber particle board which has high wood utilization rate, is difficult to warp or deform, has a flat panel and is easy to realize mechanical production by processes of drying, sizing, paving and the like. In the technical scheme disclosed by the invention, the method for preparing the fiber particle board is characterized by comprising the following steps of: (1) small-diameter wood milling; (2) wafer grinding; (3) pipeline sizing; (4) fiber fine wood wool drying; (5) paving (6) prepressing; (7) hot pressing; and (8) post processing. The method for preparing the fiber particle board is suitable for the industries of furnitures, decoration and the like.

Description

technical field [0001] The invention relates to a preparation method of fiber particleboard. It is suitable for furniture and home decoration industry, etc. Background technique [0002] At present, natural forest resources are extremely scarce in the world, and the supply and demand of timber resources are tense, especially the contradiction between supply and demand in mine is very prominent. However, the raw materials used in my country's timber industry have changed from natural forests to the development and utilization of fast-growing small-diameter timber in artificial forests. Therefore, how to effectively develop and utilize my country's fast-growing small-diameter timber resources has always been a major problem and research focus for forestry workers in my country. . [0003] In order to efficiently utilize timber resources, Australian scientist J.D. Coleman proposed a novel and unique idea of ​​using small-diameter timber to manufacture recombined wood in 1973, ...
