Abstract

The invention relates to a method for producing veneers and wood jointed boards, comprising the following steps of: breaking up rubber wood used as raw material into big square rods for manufacturing the veneers, and breaking up remaining small materials into small square rods; antiseptic material boiling: boiling the big square rods with water and then keeping the constant temperature for 4.5-6 hours and then taking the big square rods out; boiling the small square rods with the water and then keeping the constant temperature for 1.5-2 hours; adding 20kg/m<3> of borax, 15kg/m<3> of boric acid and 2-6kg/m<3> of sodium pentachlorophenate to the water when the materials are boiled; then dispersing, drying, planing, shuttle tooth gluing, toothing, board arranging, gluing and board jointing, then gluing and stacking to certain thickness, and then slicing the veneers, and drying the veneers at the temperature of 80-160 DEG C to obtain veneer finished products and then casing. In the invention, the rubber wood veneers with high quality are produced by taking the rubber wood as the raw material by using a special production method. The production method overcomes the defects of the prior art and opens up the new application of the rubber wood. Moreover, the product has high quality, high yield and cost reduction and does not discolor or deform.

Description

The production method of a kind of wooden skin and wooden jigsaw

Technical field

The present invention relates to wooden processing technique field, specifically the production method of a kind of wooden skin and wooden jigsaw.

Background technology

Natural veneer because its very thin thickness, in the production to the having relatively high expectations of timber, need reasonable timber could the quality of production wooden skin preferably.Rubber wood timber is difficult to produce the measured wooden skin finished product of matter because wooden unstability produces variable color and distortion easily with existing method.

Summary of the invention

The purpose of this invention is to provide a kind of method of producing wooden skin and wooden jigsaw with rubber wood timber.

The production method of wooden jigsaw of the present invention is carried out according to the following steps:

1) raw material: take rubber wood timber as raw material, be broken down into system generous of wooden skin after, remaining small powder solution becomes little side's bar;

2) the anticorrosion material that boils: constant temperature keeps playing pot in 4.5～6 hours behind generous the water boil, and constant temperature kept 1.5～2 hours behind little side's bar water boil, puts into borax 20～kg/m in the water when boiling material ³, boric acid 15～kg/m ³, pentachlorphen sodium 2～6kg/m ³

3) generous and little side's bar take the dish out of the pot and scatter in rear 10 minutes, avoid sealing for a long time in a pile variable color;

4) oven dry: enter kiln drying with generous with little side's bar, the greenhouse degree is 50～85 ℃ in the kiln, dries about 24 hours for generous, little side's bar oven dry about 7 days, kiln discharge when making then kiln temperature drop to 45～50 ℃;

5) by each face of planing behind the specification fracture;

6) carry out shuttle tooth → gluing → toe joint → row's plate → gluing → jigsaw with generous with little side's bar and become satisfactory generous wood strip piece and little side's wood strip piece;

7) generous wood strip piece planish on four sides rear gluing, be stacked high to certain thickness (to 38～42cm), carry out then wooden skin slicing, the oven dry of wood skin, get wooden skin finished product vanning after 80～160 ℃ of (according to wooden tape measure cun size, thickness, in this scope, selecting bake out temperature) oven dry of bake out temperature.

The present invention produces high-quality rubber wood timber wood skin with special production method, and utilizes the residue small powder to produce wooden jigsaw take rubber wood timber as raw material, takes full advantage of natural timber.Production method of the present invention has overcome the deficiencies in the prior art, has opened up the new purposes of rubber wood timber, and good product quality, nondiscolouring, indeformable, and the yield rate height, cost reduces.

The specific embodiment

Embodiment 1:

2) the anticorrosion material that boils: constant temperature keeps playing pot in 4.5 hours behind generous the water boil, and constant temperature keeps playing pot in 1.5 hours behind little side's bar water boil, puts into borax 20kg/m in the water when boiling material ³, boric acid 15kg/m ³, the addition of pentachlorphen sodium is: do day: square bar 7 days take interior processing as 2kg/m ³, that processed in 10～14 days is 3kg/m ³, that processing is 4kg/m more than 15 days ³, the control fire can not be too big after the water boiling, in order to avoid liquid medicine runs off;

4) oven dry: enter kiln drying with generous with little side's bar, the greenhouse degree is 65 ℃ in the kiln, dries about 24 hours for generous, little side's bar oven dry about 7 days, kiln discharge when making then kiln temperature drop to 45～50 ℃;

5) by each face of planing behind the specification fracture;

6) carry out shuttle tooth → gluing → toe joint → row's plate → gluing → jigsaw with generous with little side's bar and become satisfactory generous wood strip piece and little side's wood strip piece (shuttle tine length: 0.9cm, toe joint side's bar length keeps the plus tolerance of 2～3cm),

7) generous wood strip piece planish on four sides rear gluing, be stacked high to certain thickness to 38～42cm, carry out then wooden skin slicing, the oven dry of wood skin, 100～160 ℃ of bake out temperatures are (according to wooden tape measure cun size, thickness, in this scope, select bake out temperature, be about 140 ℃ such as the thick temperature of 0.4mm, about 110 ℃ of thick temperature of 0.3mm) after the oven dry wooden skin finished product vanning.It is by the splicing of specification requirement size that assembly is pulled, two ends equating then, and white glue with vinyl is all coated on both sides, prevents to split.

Embodiment 2:

Following steps as different from Example 1:

2) the anticorrosion material that boils: constant temperature keeps playing pot in 6 hours behind generous the water boil, and constant temperature keeps playing pot in 2 hours behind little side's bar water boil, puts into borax 20kg/m in the water when boiling material ³, boric acid 15kg/m ³, the addition of pentachlorphen sodium is: rainy season the sky: square bar 7 days take interior processing as 4kg/m ³, that processing is 6kg/m more than 7 days ³The control fire can not be too big after the water boiling, in order to avoid liquid medicine runs off;

4) oven dry: enter kiln drying with generous with little side's bar, the greenhouse degree is 85 ℃ in the kiln, dries about 20 hours for generous, little side's bar oven dry about 6 days, kiln discharge when making then kiln temperature drop to 45～50 ℃.

Claims

1. the production method of a wooden skin and wooden jigsaw is characterized in that carrying out according to the following steps:

3) generous and little side's bar take the dish out of the pot and scatter in rear 10 minutes;

5) by each face of planing behind the specification fracture;

7) generous wood strip piece planish on four sides rear gluing, be stacked high to certain thickness, carry out then wooden skin slicing, the oven dry of wooden skin, 80～160 ℃ of bake out temperatures, after the oven dry wooden skin finished product vanning.
