Three ways to process eco-friendly furniture wood-Reactive Polyurethane Hot-melt Adhesive (PUR)

April 20,2022
It will be a dream come true if I can buy a house of my own. When you move to a new place, the objects you need to buy must include furniture. Furniture not only provides you the convenience of your daily life, but the beautiful appearance can make your room has a unique style. To let the customers have various options, the style of furniture has become more and more different. Do you ever think of the processing of furniture? This article will introduce three ways to use reactive polyurethane hot-melt adhesive (PUR) to process the wood and let you know the composition of the furniture.

Cladding Processing

Cladding processing means using adhesive to wrap the substrate together and prolong the life of the substrate. Take furniture as an example, the furniture use cladding processing usually window frame, cabinet decoration, kick plates, and door frame decoration. The main appearance is a round outer frame.
The substrate of the cladding process can be divided into two kinds of materials, which are MDF and LVL.

1. Medium Density Fiberboard (MDF) can be called density fiberboard. It can be divided by the density as high-density fiberboard, medium-density fiberboard, and low-density fiberboard. Fiberboard is composed of wood fiber and other fiber that compress together. The advantages are even structure, impact resistance, and stable function, so it usually is made of furniture and other products.

2. Laminated Veneer Lumber (LVL) uses round wood as raw materials, it is also the wood that is processed through crop and compression. During the cropping process, it can separate the cracks and defects of the round wood. Its advantages would be stable quality, even intensity, and is usually applied in the huge wooden structure.

Laminating Processing

The definition of laminating processing is using the adhesive to laminate the decorating materials on the surface of another material, it is usually applied in furniture, kitchen utensils, and automobile decoration. The first step of processing is sanding the surface, making the surface smooth, and matching the laminating materials. Next, it would use the adhesive to glue the decorating materials to the surface and employ the cold press machine or hot press machine to compress and cure. The last step is correct the wood surface and a wood process with laminating is done.

Laminate Flooring

Laminate flooring is a material processed with more than two kinds of wood. There will be composed of three layers, which are the faceplate, substrate, and soleplate. Compared with the round wood floor, laminate flooring has these advantages:

1. It’s not easy to warp and deform.
If you use the round wood floor, because it doesn’t through the specfic process, it’s easily influenced by the environment humidity changing, and caused the warp and deform.

2. Easily to maintain
Normally, you can wipe the laminate flooring with a mop to do efficient maintenance.

3. High wear resistance
Because the surface of laminate flooring has extra processing, the wear resistance would be better than the round wood floor.

4. Eco-friendly
If you use the reactive polyurethane hot-melt adhesive (PUR) as the adhesive of wood, because the adhesive is a solvent-free type, it doesn’t emit the VOCs that are harmful to the environment. Moreover, using the laminate flooring can efficiently reduce the usage of wood, and reach the function of environmentally friendly.


The Advantages of Reactive Polyurethane Hot-melt Adhesive (PUR)

1. Eco-friendly and not harmful
The reactive polyurethane hot-melt adhesive (PUR) is a solvent-free adhesive, it doesn’t emit the volatile organic compounds (VOCs) to the environment and cause pollution, it also doesn’t contain the formaldehyde. From the interior decoration perspective, because the VOCs would be harmful to humans, so using the reactive polyurethane hot-melt adhesive (PUR) as the adhesive of furniture and building materials is very important.

2. Saving energy
There will be no need for a drying machine to let the adhesive solid during the process, so it can save the energy of using the drying machine.

3. High adhesion after the adhesive is finished
After the reactive polyurethane hot-melt adhesive (PUR) meets with heat and is active with the humidity, it means the adhesive is finished. The finished adhesive has higher adhesion than before.
