China board trading network news:
Paint-free boards are papers with different colors or textures that are soaked in melamine resin adhesive and then dried to a certain degree of curing. They are laid on particleboard, moisture-proof boards, medium-density fiberboard, plywood, blockboard, or other materials. Above the solid wood panels, the decorative panels made by hot pressing are often called melamine panels.
First, the production process
"Melamine" is one of the resin adhesives used in the manufacture of this type of board. After the paper with different colors or textures is immersed in the resin, it is dried to a certain degree of curing, and it is decorated by laying it on wood board or solid wood board. The board, the name of the specification, is a melamine-impregnated paperboard facing board, saying that its melamine board actually speaks out part of its finish.
Melamine impregnated plastic film paper manufacturing process: plastic glue → glue (add curing agent, release agent, etc.) → first impregnation (mixed with melamine formaldehyde resin and urea formaldehyde resin) → first drying → second impregnation (melamine formaldehyde Resin) → second drying → cooling cut.
Second, the material and structure
It is reported that there are currently three kinds of paint-free boards on the market:
1. There is a problem of non-environmental protection for the core board and the non-painted board with melamine finish, which cannot be duplicated and the internal stress is unbalanced, resulting in the problem of easy deformation.
2. The unpainted plate market of triple-ply laminated core substrates is generally easy to open.
3, plate core plus plate in the re-adhesive melamine finish paint-free plate, although high adhesion, stability, but the process requirements are extremely high.
In addition to reference to the structure of the above board, we must be able to distinguish between good and bad from the board surface, that is, the carbonization point.
Carbonization point: The non-painted board is observed at a 45-degree angle on the lower side of a good light. If there is an unsmooth small piece on the smooth surface of the board, it is a charring phenomenon that is produced during the production process.
The carbonization point is the most serious problem on the board surface during the production process of the paint-free board. It is also an insurmountable technical problem for the domestic paint-free board manufacturers. The surface carbonization rate of similar paint-free board is as high as 30% or more and the surface is carbonized. Seriously affect the life of the paint-free board and decorative effect.
Third, the advantages
The non-painting decoration material has a natural texture, a clear wood grain, and can be compared with the original wood. There are all kinds of wood species in the world and there is no color difference on the surface of the product. Paint-free decorative materials also have the characteristics of self-extinguishing, washable, wear-resistant, moisture-proof, anti-corrosion, anti-acid, anti-alkali, non-stick dust, and moldy blackness. The products are well-designed and the color matching is reasonable.
In addition, the construction of paint-free decorative materials is convenient, good sawing, good cutting, never breaking, repairing and trimming the use of paint-free lines, the effect is elegant, the cost is reduced, and it is green, non-toxic, tasteless and pollution-free cross century. A new generation of paint-free decorative materials will lead the new trend of decorative materials with its high-end benefits.
Fourth, the main purpose
Because the paint-free board has the characteristics of environmental protection and free paint, it can meet the requirements of modern people for rapid environmental protection and convenient decoration. It can be used in cloakrooms, closets, wall decorations, ceilings, wardrobes, bookcases, tables and chairs, shoe cabinets, bathroom cabinets, wine Cabinets and other decoration furniture.
V. Environmental performance
There is no absolute environmental protection plate, the main source of common plate pollution comes from the glue and the paint used in the processing of the plate, and the advantage of the paint-free plate over other plates is that it is free of paint and eliminates the pollution of benzene, paint, etc.
The above information, relevant Baoyuan plate supply information, plate purchase, etc. Please pay attention to the Chinese plate trading network
