Problems solved by technology

Hard wood veneer (such as mahogany tree veneer, mountain twig veneer, brazil rosewood veneer and huanghuali veneer, etc.) is prone to cracking during the veneering process if it is directly pasted without treatment due to the hard wood. Bubble phenomenon, and during the service life after the processing is completed, affected by the temperature difference, the phenomenon of veneer cracking and paint delamination may also occur, and the quality of the product cannot be guaranteed

Embodiment 1

[0023] A processing technique for hard veneer, comprising the following processes:

[0024] (1) softening treatment:

[0025] ①Put the sheet curing agent: water = 2:1 weight ratio components into the corresponding container, and prepare the softening potion. The sheet curing agent is produced by akzonobel company;

[0026] ② Soak each piece of hard veneer in a container with softening potion for 2 minutes to soften it;

[0027] ③Wrap the soaked hard veneer with a film and store it in a dark place for more than 24 hours. There are many air holes on the film to make the softening potion remaining on the hard veneer slowly volatilize.

[0028] (2) drying treatment:

[0029] Place the softened hard veneer neatly on a hot press for drying. The hot pressing temperature is controlled above 100°C, the hot pressing pressure is 8MPa, and the drying time is 10 minutes. During the drying process, the hot press needs to be The hard veneer can be dried better by multiple depressurization...

Embodiment 2

[0036] A processing technique for hard veneer, comprising the following processes:

[0037] (1) softening treatment:

[0038] ①Put the sheet curing agent: water = 4:1 weight ratio components into the corresponding container, and prepare the softening potion. The sheet curing agent is produced by akzonobel company;

[0039] ② Soak each piece of hard veneer in a container with softening potion for 5 minutes to soften it;

[0040] ③Wrap the soaked hard veneer with a film and store it in a dark place for more than 24 hours. There are many air holes on the film to make the softening potion remaining on the hard veneer slowly volatilize.

[0041] (2) drying treatment:

[0042] Place the softened hard veneer neatly on the hot press for drying. The hot pressing temperature is controlled above 100°C, the hot pressing pressure is 6MPa, and the drying time is 15 minutes. During the drying process, the hot press needs to be The hard veneer can be dried better by multiple depressurizati...

Embodiment 3

[0049] A processing technique for hard veneer, comprising the following processes:

[0050] (1) softening treatment:

[0051] ①Put the sheet curing agent: water = 2:1 weight ratio components into the corresponding container, and prepare the softening potion. The sheet curing agent is produced by akzonobel company;

[0052] ② Soak each piece of hard veneer in a container with softening potion for 3 minutes to soften it;

[0053] ③Wrap the soaked hard veneer with a film and store it in a dark place for more than 24 hours. There are many air holes on the film to make the softening potion remaining on the hard veneer slowly volatilize.

[0054] (2) drying treatment:

[0055] Place the softened hard veneer neatly on the hot press for drying. The hot pressing temperature is controlled above 100°C, the hot pressing pressure is 8MPa, and the drying time is 5 minutes.

Abstract

The invention discloses a machining process of hard veneers. After the hard veneers are softened and dried, wood becomes soft, so that veneer splicing machining is smoother and the splicing effect is better in veneer splicing and hotly pressing veneer laminating processes; in the hotly pressing veneer laminating process, a phenomenon that the veneers are foamed can be effectively avoided; an obtained veneer laminated product is subjected to fine machining including paint spraying, fabric process, package and the like to prepare a veneer laminated furniture product; and in a utilization period of positive and negative temperature difference, phenomena that the veneers are cracked and paint is delaminated can be effectively avoided.

Description

technical field [0001] The invention relates to the field of plate processing, in particular to a processing technology of hard veneer. Background technique [0002] Existing products such as veneer furniture usually use natural solid wood and / or boards as substitute substrates, and the substitute substrates are initially processed into semi-finished products according to conventional procedures and methods. Paste natural veneer on the outer surface and inner surface of the semi-finished product to make a semi-finished product with skin. The semi-finished products of pre-skin furniture are finished by spraying paint, cloth art, packaging, etc. in turn to make finished products of pre-skin furniture. Various types of veneer products can be made by selecting veneers of different materials. Hard wood veneer (such as mahogany tree veneer, mountain twig veneer, brazil rosewood veneer and huanghuali veneer, etc.) is prone to cracking during the veneering process if it is directl...
