Embodiment 1

[0018] A method for processing Chinese fir densified furniture profiles, the specific steps are:

[0019] (1) Preparation of thin plate: The thinning fir wood is used as the raw material, and the thin plate is cut into a thin plate with a thickness of 12mm. The two sides of the thin plate are rolled with pores of a certain density, and the moisture content is controlled above 70% to ensure the implementation of the softening process;

[0020] (2) Prefabrication of plastic film: According to the use of the material, raw or recycled polyethylene plastic film can be selected as the bonding material, and cut into corresponding specifications. The cost of the two plastic films is different;

[0021] (3) Softening treatment of the sheet: The sheet is treated with microwaves with an output power of 500W, and the treatment time is 4 minutes, so that the sheet is softened and the moisture content is controlled below 15%;

[0022] (4) Assembling the blank: Determine the compression rati...

Embodiment 2

[0026] A method for processing Chinese fir densified furniture profiles, the specific steps are:

[0027] (1) Preparation of thin plate: The thinned fir wood is used as the raw material, and the thin plate is cut into a thin plate with a thickness of 10mm. The pores of a certain density are rolled on both sides of the thin plate, and the moisture content is controlled above 70% to ensure the implementation of the softening process;

[0028] (2) Prefabrication of plastic film: According to the use of the material, raw or recycled polyethylene plastic film can be selected as the bonding material, and cut into corresponding specifications. The cost of the two plastic films is different;

[0029] (3) Softening treatment of the sheet: The sheet is treated with microwaves with an output power of 550W, and the treatment time is 3 minutes, so that the sheet is softened and the moisture content is controlled below 15%;

[0030] (4) Assembly: Determine the compression rate according to ...

Embodiment 3

[0034] A method for processing fir densified furniture profiles, comprising the following steps:

[0035] (1) Preparation of thin plate: The thinned fir wood is used as the raw material, and the thin plate is cut into a thin plate with a thickness of 8 mm. The two sides of the thin plate are rolled with pores of a certain density, and the moisture content is controlled above 70% to ensure the implementation of the softening process;

[0036] (2) Prefabrication of plastic film: According to the use of the material, raw or recycled polyethylene plastic film can be selected as the bonding material, and cut into corresponding specifications. The cost of the two plastic films is different;

[0037] (3) Softening treatment of the thin plate: The thin plate is treated with microwaves with an output power of 400W, and the processing time is 6 minutes, so that the thin plate is softened and the moisture content is controlled below 15%;

[0038] (4) Assembly: Determine the compression r...

Abstract

The invention belongs to the technical field of base material preparation of wood processing and furniture production, and particularly relates to a China fir dense furniture profile and a processing method. A plastic film replaces an adhesive to prepare the dense furniture profile; the thickness of China fir sheets is 8-12 mm, the width is selected according to the specification of the furniture profile, and the sheets are subjected to microwave softening treatment, then assembled to be put into a home-made pressurization mold and pressurized and glued into the dense furniture profile under the certain hot-pressing conditions. The processing method ensures that the base material is free of aldehyde and environmentally friendly, and the processing method is a processing technology capable of efficiently improving the additional value of middle cutting wood of fast-growing China firs. The consumption concepts of environmental protection, safety and health in the current wood industry and furniture industry are met, and the application fields are wide.

Description

technical field [0001] The invention belongs to the technical field of base material preparation for wood processing and furniture production, and in particular relates to a fir densified furniture profile and a processing method. Background technique [0002] The growth process of Chinese fir fast-growing forest requires timely thinning to promote tree growth. The yield of fir thinning is high, but the material of fir is poor, soft, easy to absorb moisture, low in practical value, and its utilization is limited. At present, it is mainly used for packaging materials, disposable chopsticks and blockboard core boards, etc. The utilization rate of wood and the added value of products are extremely low. Improving the density of fir interwood, that is, densification technology, is an important way to expand the application field of fir interwood. Research on wood densification at home and abroad mainly focuses on the use of low-molecular PF, MP and other resins or through cross...
