Abstract

The invention discloses a method for preparing wood shavings by using waste wood, which comprises the following steps of S1, selecting raw materials; s2, shaving; s3, shaving and crushing; the water content of the selected material in the processing method is within the range of 40% -60%, so that the problem that the prepared wood shavings influence the later glue spinning effect when the water content is too high is effectively avoided, the problem that too many fine wood shavings and crushing are generated when the wood shavings are sliced when the water content is too low is also avoided, and the loss of glue and blades is reduced; the phenomena of low strength of wood shavings, easy conglomeration of glue mixing, deep surface color of the shaving board and easy stripping when the bark content in the raw material is more than 10 percent are avoided; the normal production of the later stage working procedure is further ensured by re-crushing the wood shavings.

Description

Method for preparing wood shavings from waste wood

Technical Field

The invention belongs to the technical field of wood shaving preparation, and particularly relates to a method for preparing wood shavings by using waste wood.

Background

With the rapid development of economy and the advancement of science and technology in various regions, wood becomes an indispensable part of modern society, people use wood to manufacture a plurality of furniture and artworks, wood shavings become the most main source for manufacturing artworks by wood,

however, the existing wood shavings are produced into excessive fine wood shavings and crushed, and the glue amount and the loss of the blades are excessive sometimes; the strength of the shaving is low, the glue is easy to agglomerate, and the phenomena of deep surface color and easy peeling of the shaving board occur;

an effective solution to the problems in the related art has not been proposed yet.

Disclosure of Invention

In order to achieve the above object, the present invention adopts a technical scheme that the present invention provides a method for preparing wood shavings from waste wood, comprising the steps of, S1, selecting raw materials; s2, shaving; s3, shaving and crushing;

preferably, in step S1, the raw materials are: logs, logging residues, wood processing residues.

Preferably, in step S1, the water content of the raw material is 40% to 60%.

Preferably, in step S1, the bark content in the raw material is < 10%.

Preferably, in step S2, the wood shavings are C-shaped wood shavings.

Preferably, the thickness of the C-shaped shaving wood chips is 0.2 mm; the length-thickness ratio of the surface layer wood shavings is 150-; the length-thickness ratio of the core layer wood shavings is about 60.

Preferably, in step S2, the wood shavings include direct wood shavings and chips.

Preferably, the material of the direct shaving sheet is wood with regular shape and large diameter grade.

Preferably, the direct flaking equipment is a disc flaker; a drum flaker.

Preferably, if the raw material has irregular shapes, such as wood chip sizes with length of 30-50mm, width of 20mm and thickness of 12-15 mm; the size of the wood shavings: 10-30mm, about 10mm wide and 0.3-0.7mm thick, wherein the wood is processed into wood chips by a chipping machine; then, a wood chip is processed into wood shavings by a flaker; the equipment is a drum chipper or a disc chipper.

Has the advantages that: compared with the prior art, the processing method has the advantages and positive effects that the moisture content of the selected material is within the range of 40% -60%, the problem that the prepared wood shavings influence the later glue spinning effect when the moisture content is too high is effectively avoided, too much fine wood shavings and crushing are generated when the wood shavings are sliced when the moisture content is too low is also avoided, and the loss of glue and blades is reduced; the phenomena of low strength of wood shavings, easy conglomeration of glue mixing, deep surface color of the shaving board and easy stripping when the bark content in the raw material is more than 10 percent are avoided; the normal production of the later stage working procedure is further ensured by re-crushing the wood shavings.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Examples

In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described with reference to the following examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments of the present disclosure.

Examples, as can be seen from the specification, the present disclosure provides a method for preparing wood shavings from waste wood, comprising the steps of, S1, selecting raw materials; s2, shaving; s3, shaving and crushing;

further, in step S1, the raw materials are: logs, logging residues, wood processing residues.

In step S1, the water content of the raw material is 40%.

Further, in step S1, the bark content in the raw material is less than 10%.

In step S2, C-shaped wood shavings are used as the wood shavings.

Further, the thickness of the C-shaped wood shaving is 0.2 mm; the length-thickness ratio of the surface layer wood shavings is 150-; the length-thickness ratio of the core layer wood shavings is about 60.

Further, in step S2, the wood shavings include direct wood shavings and shavings.

Further, the direct shaving sheet is made of wood with regular shape and large diameter.

Further, the direct flaking equipment is a disc flaker; a drum flaker.

Further, if the raw material is irregular in shape, for example, the size of the wood chips is 30-50mm long, 20mm wide and 12-15mm thick; the size of the wood shavings: 10-30mm, about 10mm wide and 0.3-0.7mm thick, wherein the wood is processed into wood chips by a chipping machine; then, a wood chip is processed into wood shavings by a flaker; the equipment is a drum chipper or a disc chipper.

Example 2

A method for preparing wood shavings from waste wood comprises the following steps of S1, selecting raw materials; s2, shaving; s3, shaving and crushing;
