How to laminating melamine paper on particle board and MDF board ?

Decorative veneer or melamine paper preparation process

1. Natural flat stitching is a pattern made of natural thin wood with radial and string-cut textures. There are three stitching methods: radial flat stitching, string flat stitching and radial flat flat stitching;

The advantages are: the natural transition of texture is the same as the smooth joining effect of wooden boards; it can be produced mechanized and is easy to scale up.

2. Combination pattern mosaic is a pattern made of thin wooden strips of certain specifications according to rules. Wood of different tones can be used to contrast the mosaic to create a strong three-dimensional decorative effect;

The advantages are: the decorative effects are flexible and diverse, suitable for manual stitching and pressing, and are often used in various parts of traditional furniture with good decorative effects.

Application of decorative veneer in American furniture manufacturing

Flat veneer can be selected according to the needs of furniture design, with a certain texture and color of veneer, and then mechanically or manually assembled into a decorative veneer with a specified pattern, and then hot-pressed and glued. It is to cover ordinary wood or artificial board products under certain conditions. Integrated finishing method. This method is widely used, and the important link is the combination of thin wood splicing patterns.

1) Cut thin wood crosswise with thin veneer shearing machine

Cut stacks of thin wood (50 mm) to the required length using a veneer cross shear.

2) Longitudinal cutting of thin wood

The veneer shearing machine is used in two forms: unilateral shearing and bilateral shearing to cut both sides of the stack of thin wood (20-80 mm) together. The edges of the thin wood that are flush with each other are straight and free from defects such as cracks and burrs, ensuring that the joints of the thin wood are tight.

3) Flatten thin wood

Use a press to heat the laminated thin wood (20 mm) to 110 degrees and pressurize it to 1Mpa. The pressurization time is maintained for 5 to 20 minutes. This is called flattening of the thin wood so that it can smoothly enter the next process; the moisture content is 8% to 10 %.

4) Thin wood splicing

The veneers are precisely cut into the specified specifications, and special materials are used to connect them into sheets of the required specifications. Common splicing methods include: tape splicing, glue line splicing, glue splicing, and non-woven fabric splicing.

① Tape tape splicing method: After assembling the pattern of thin wood of a certain specification, use tape tape to connect the fronts into sheets, and then sand the surface tape after veneer. The disadvantages of this method are: sanding is time-consuming and labor-intensive, and the residual glue in the brown eyes of the thin wood will discolor the thin wood. Currently, this method is rarely used.

② Glue line splicing method: Use glass fiber with hot melt glue as the bonding material; after heating, paste it on both sides of the thin wood joints, forming an “I” shape distribution, and it will be close to the surface of the base material without being exposed when covering. This method uses a toothed glue line veneer splicing machine, which is often used to splice thin veneers with a thickness of 0.2 to 0.3 mm.

③ Glue splicing method: Use a veneer splicing machine and adhesive to splice thin wood into sheets; the characteristic is that the splicing material is not exposed, the seams are tight and the connection strength is high, which makes up for the shortcomings of splicing methods such as glue lines. The thin wood spliced by this method is often used for Profile coating, special-shaped component surfaces, edge banding rolls; used for thin wood with a thickness of 0.4 to 3 mm.

④ Non-woven fabric splicing method: use non-woven fabric coated with PVAC glue on the back of the textured thin wood to form a sheet; the characteristic is that the connection strength of the thin wood is increased; often used for surface decoration of parts with large curvatures and The splicing of ultra-thin wood.

⑤ Double-end reinforcement of thin wood: The two ends of the spliced thin wood can be reinforced with glue lines to prevent the edges from being damaged during use and avoid unnecessary losses caused by damage to the thin wood.

⑥ Thin wood repair: Unqualified products with defects such as seams, cracks, spots, and wire drawing should be repaired in time. Commonly used methods include: glue injection method, wood fiber inlay method, etc. , this method is the mainstream trend in furniture industry applications.

⑦ Thin wood finger jointing: Short and narrow thin wood strips are spliced on the thin wood finger splicing machine. You can also join them to a certain width and then lengthen them. The spliced thin wood strips can be wound into a roll of a certain length, and then rolled The machine will cover the back of the non-woven fabric soaked with PVAC glue. The thin wood roll that has been compounded to increase its strength is sanded to a certain degree of smoothness by a high-precision sander, and then further cut into edge-sealing rolls. Edge wrapping rolls, etc., suitable for special-shaped edge sealing and special-shaped wrapping needs.
