How to prevent the cracking of melamine boards? During the use of melamine board manufacturers, boards may sometimes crack to varying degrees, affecting the appearance and use of the boards. Therefore, we need to understand the causes of cracking of melamine boards and deal with them in a timely manner.
Normally, the cracking of melamine board is caused by the moisture content of the selected wood being too high or too low. If the moisture content of the wood does not reach an equilibrium value, it is easy for the stress to be different due to the change of dryness and humidity in the external environment, resulting in the cracking of paulownia melamine board. Therefore, in terms of selection, try to go to a regular melamine board manufacturer and choose locally produced melamine board. Foreign or imported wood is easily affected by thermal expansion and contraction in the local area, and it is easy to deform or crack.
If the melamine board is cracked, the melamine ecological board manufacturer recommends going to the building materials market to buy some putty, mixing some flour and water, and then filling it into the cracks. It will not be visible after surface treatment, but this does not make us ignore the importance of maintenance.
The boards produced by melamine board manufacturers are based on particleboard and density board. They are widely used in many fields, especially in home decoration. What are the advantages and disadvantages of such a board?
Melamine board is a composite material, green and environmentally friendly, and the material does not contain formaldehyde; the surface is smooth, beautiful, and elegant in color; paint-free, non-toxic, moisture-proof, flame-retardant, and non-volatile odor. The surface has good hardness, impact resistance, sound insulation, shockproof, no shrinkage, no cracking, good durability, and can be curved. However, there are also some shortcomings in use that we need to understand clearly. The use of melamine board requires high process requirements for cutting and edge sealing, otherwise it is easy to break. And the feel is significantly different from solid wood when touched。
How to use melamine board
Melamine board is a kind of board widely used in the fields of construction and furniture. It has the advantages of high strength, water resistance, fire resistance, corrosion resistance, and environmental protection. This article will introduce how to use melamine board, including board cutting, splicing, painting and other aspects.
1.Board cutting
Before using melamine board, you need to cut the board first. Common cutting methods are manual cutting and machine cutting. Manual cutting: First place the board on a flat workbench, then measure it according to your needs, and use a saw or cutting tool to cut the board. Machine cutting: For large-area board cutting, you can use machines such as electric saws and laser cutters for fast and accurate cutting.
2.Board splicing
When using melamine boards for construction or furniture making, it is often necessary to splice the boards together. There are several ways to splice boards.
*Direct splicing method
Place two boards side by side and splice them together using screws, glue, etc.
This method is simple and easy, and the splicing points are strong, which is suitable for some building structures and furniture making.
*Seam splicing method
The seam splicing method is to process the edges of two boards into seam shapes and then splice them together. After painting, the seam looks like a whole board, and the appearance is more beautiful. It is suitable for some buildings or furniture with high requirements for appearance.
*Mortise and tenon splicing method
The mortise and tenon splicing method is to cut and process two boards into tenons and mortises that match each other, and then insert the tenons into the mortises to complete the splicing. The splicing points of this method are stronger than the direct splicing method, which is suitable for some furniture that needs to be disassembled and installed frequently.
3.Painting
After splicing, polishing and other processing, melamine boards usually need to be painted. Painting can protect the surface of the board, making it more wear-resistant, beautiful, waterproof, etc.
The steps of painting are as follows:
*Clean the surface: Before painting, you need to clean the surface of the board to remove dust, grease and other dirt on the surface.
*Primer painting: After the surface is clean, apply primer to enhance the adhesion and water resistance of the coating
*Polishing: After the primer is dry, use sandpaper or a grinder to polish the board to make the surface flat and remove uneven parts.
*Topcoat painting: After polishing, apply a layer of topcoat to protect the surface, enhance color and gloss.
