Problems solved by technology

[0003] However, if solid wood is used as furniture now, the price is relatively high, and if solid wood is not maintained for a long time, it will often lead to cracking in a relatively dry environment with high temperature, causing huge losses and waste. The price is cheap during the preparation process, and it will not cause cracking and deformation. It has high strength and good toughness, and is easy to further process into various shapes. However, when plywood is produced now, manufacturers often reduce the production process in order to increase production. process, resulting in plywood cracking in the final stage of use, poor quality, and unable to meet the needs of the market

Embodiment 1

[0018] This embodiment provides a kind of processing method of plywood, and the operation steps are as follows:

[0019] 1) Log processing: Saw the logs, then cook and peel them, and peel the peeled wood sections for veneer peeling.

[0020] 2) Drying: The veneer after rotary cutting is firstly cleaned, and then dried at a temperature of 73° C., and finally cooled at room temperature.

[0021] 3) Gluing treatment: apply a layer of adhesive to the surface of the veneer after rotary cutting, stack 6-8 veneers together, and add a piece of camphor veneer on both sides of the superimposed veneer.

[0022] 4) Press plate molding: Fix the veneer in step 3) on the die sleeve of the press machine, control the temperature at 81°C, and press the plate for 3 hours.

[0023] The log used in the log processing step is poplar.

[0024] The drying time in the drying operation step is 2 hours.

[0025] The plywood after the press plate molding is carried out vacuum drying again, and the dry...

Embodiment 2

[0027] This embodiment provides a kind of processing method of plywood, and the operation steps are as follows:

[0028] 1) Log processing: Saw the logs, then cook and peel them, and peel the peeled wood sections for veneer peeling.

[0029] 2) Drying: The veneer after rotary cutting is firstly cleaned, and then dried at a temperature of 61° C., and finally cooled at room temperature.

[0030] 3) Gluing treatment: apply a layer of adhesive to the surface of the veneer after rotary cutting, stack 6-8 veneers together, and add a piece of camphor veneer on both sides of the superimposed veneer.

[0031] 4) Press plate molding: Fix the veneer in step 3) on the mold sleeve of the press machine, control the temperature at 93°C, and press the plate for 2.5 hours.

[0032] The log used in the log processing step is poplar.

[0033] The drying time in the drying operation step is 1 hour.

[0034] The plywood after the pressed plate is formed is vacuum-dried again, and the drying tem...

Embodiment 3

[0036] This embodiment provides a kind of processing method of plywood, and the operation steps are as follows:

[0037] 1) Log processing: Saw the logs, then cook and peel them, and peel the peeled wood sections for veneer peeling.

[0038] 2) Drying: The veneer after rotary cutting is firstly cleaned, and then dried at a temperature of 67° C., and finally cooled at room temperature.

[0039] 3) Gluing treatment: apply a layer of adhesive to the surface of the veneer after rotary cutting, stack 6-8 veneers together, and add a piece of camphor veneer on both sides of the superimposed veneer.

[0040] 4) Press plate molding: Fix the veneer in step 3) on the die sleeve of the press machine, control the temperature at 86°C, and press the plate for 2.6 hours.

[0041] The drying time in the drying operation step was 1.7 hours.

[0042] The plywood after pressing is then vacuum-dried. The drying temperature is controlled at 24° C. for 4.5 hours.

Abstract

The invention provides a machining process method for plywood, and relates to the field of wood machining. Machining operation of the plywood is carried out through four steps including log machining, drying, glue passing processing and pressing plate molding. The compressive strength and the toughness of the plywood are sufficiently improved, the toughness can be improved to a certain degree through the structure of the plywood, cracking is reduced, the production rate of inferior-quality products is reduced, the overall technological process is novel, and further application and popularization can be carried out.

Description

technical field [0001] The invention relates to the field of wood processing, in particular to a processing method for plywood. Background technique [0002] With the current industrialization, people now demand more and more from nature. In people's daily life, because of aesthetic requirements, they often choose more environmentally friendly and natural wood as furniture instead of the current crafts. Plastic, rubber, metal and other products. [0003] However, if solid wood is used as furniture now, the price is relatively high, and if solid wood is not maintained for a long time, it will often lead to cracking in a relatively dry environment with high temperature, causing huge losses and waste. The price is cheap during the preparation process, and it will not cause cracking and deformation. It has high strength and good toughness, and is easy to further process into various shapes. However, when plywood is produced now, manufacturers often reduce the production process...
