melamine faced boards, whose substrates are particleboard, MDF, plywood, etc, are made by bonding the substrate and the surface. The surface veneers are mainly domestic and imported. Because they are fireproof , Anti-wear, waterproof immersion treatment, the use effect is the same as the composite wood floor.
melamine coated mdf full name is melamine impregnated adhesive film paper veneer wood-based board. Melamine covered mdf is to soak paper with different colors or textures in melamine resin adhesive, then dry to a certain degree of curing, and pave it on particle board, moisture proof mdf board, medium density fiberboard, plywood, blockboard, multiplex MDF board or other melamine fiberboard surface, by hot pressing made up mdf decorative panels. In the production process, it is generally composed of several layers of paper, and the quantity depends on the purpose. 18mm melamine board is not a new product, and the fancy name does not mean that the product is fresh.
Usages
melamine mdf sheets is often used in the decoration of indoor buildings and various furniture and cabinets. Some panels, walls, cabinets, cabinet laminates, etc.
Classification
According to the internal fiber form, it can be divided into two types: melamine particle board and melamine mdf board; the base material of melamine particle board is to beat wood into particles and sawdust, which are formed by, redirecting, hot pressing and gluing; the base of melamine mdf board is formed by cutting wood into sawdust, reorienting, hot pressing, and gluing. The difference between the two is: the particle board has high strength and strong nail suction ability, while the melamine faced mdf board is relatively weak.
Melamine decorative mdf board performance
1, colored melamine sheets can imitate various patterns arbitrarily, with bright color, used as a veneer of various wood-based panels and wood, with high hardness, wear resistance and good heat resistance.
2, The performance of chemical resistance is general, and 18mm melamine faced mdf board can resist the abrasion of general solvents such as acid, alkali, grease and alcohol.
3. The surface is smooth and clean, easy to maintain and clean.
Melamine board has excellent properties that natural wood can't have, so often used melamine sheets for cabinets, furniture or interior architecture.
Melamine board is a wall decoration material. Some people use melamine board 8x4 to counterfeit laminate flooring for floor decoration, which is inappropriate.
melamine sheets sizes: 2440mm×1220mm, thickness 1.5-1.8cm.
Component
"Melamine" is a kind of adhesive used to make wood. After soaking paper with different colors or textures in it, it is dried to a certain degree of solidification. Pressed decorative board, the standard name is melamine impregnated paper veneer artificial board, and its melamine decorative board is actually its surface decoration part.
Generally, it is composed of surface paper, decorative paper, covering paper and partial paper.
① Surface paper is placed on the top layer of the decorative board to protect the decorative paper, making the surface of the board highly transparent after heating and pressing, and the surface of the board is hard and wear-resistant. This kind of paper requires good water absorption performance, clean white and clean, and transparent after dipping.
② Decorative paper, that is, wood grain paper, is an important part of the decorative board. It has a background color or no background color, and is printed into decorative paper with various patterns. It is placed under the surface paper and mainly plays a decorative role. This layer requires Paper has good hiding power, impregnation and printing performance.
③ Covering paper, also called titanium white paper, is generally placed under the decorative paper when manufacturing light-colored decorative boards to prevent the bottom phenolic resin from penetrating to the surface. Its main function is to cover the color spots on the surface of the substrate. Therefore, good coverage is required. The above three types of paper were impregnated with melamine resin.
④ The bottom paper is the base material of the decorative mdf sheet, which plays a role in the mechanical properties of the board. It is impregnated with phenolic resin glue and dried. During production, several layers can be determined according to the purpose or the thickness of the decorative board.
When choosing this type of melamine furniture board, in addition to satisfactory color and texture, you can also distinguish the appearance quality from several aspects. Whether there are stains, scratches, indentations, pores, whether the color and gloss are uniform, whether there is bubbling, and whether there are partial paper tears or defects.
Advantages
The advantages of this kind of melamine laminated mdf board are: the surface is flat, the double-sided expansion coefficient of the board is the same, it is not easy to be deformed, the color is bright, the surface is more wear-resistant, corrosion-resistant, and the price is economical.
Disadvantages
The shortcomings of this kind of melamine ply board are: the edge is easy to collapse, and it can only be straight edge.
Difference
In terms of cost, most household-oriented melamine furniture grade mdf on the market uses MDF and particleboard as the base material, and higher-grade white melamine boards use blockboard (solid wood core) as the base material. In contrast, the performance of blockboard (solid wood core) is better than the former two. The internal structure of the blockboard is uniform, the bonding force is large, the deformation is small, the surface flatness is good, and the nail holding force is strong. Therefore, the waterproof melamine board using blockboard as the base material is stronger and more durable, and can better play the characteristics of panel furniture to resist assembly. The texture of MDF and particleboard is relatively loose, the nail holding power is poor, and the cost is lower than the former.
There is also the difference of the steel plate of the melamine veneer press, which can make the effect of the surface of the board, divided into smooth surface, hemp surface (coarse hemp, fine hemp and fluffy hemp), embossed surface (large relief and small relief). Matte noodles and embossed noodles are 2-3 yuan more expensive than smooth noodles, but they are generally used as cabinet doors, and generally the cabinet body is smooth.
Environmental protection
18mm melamine faced mdf is light, mildew-proof, fire-resistant, heat-resistant, shock-resistant, easy to clean, and renewable. It is fully in line with the established policy of energy saving, consumption reduction and ecological protection, so people also call it ecological board. In addition to solid wood furniture, all kinds of high-end panel furniture have the participation of high gloss melamine board. Adding melamine board to mid-to-high-end overall wardrobes can effectively prevent environmental pollution caused by formaldehyde and urea-formaldehyde resin used as preservatives. In addition, white melamine board 18mm can also replace wooden panels, aluminum-plastic panels, etc., to make mirrors and high resistance. Polished, anti-static, embossed, metal and other finishes.
white melamine mdf is a decorative board formed by hot pressing on the surface of particle board, moisture-proof board, medium density fiberboard or hard fiberboard. In the production process, it is generally composed of several layers of paper, and the quantity depends on the purpose.
The performance of MDF is better than the latter. The internal structure of the MDF is uniform, the binding force is greater than that of the particleboard, the deformation is small, and the surface is smooth. Therefore, the 12mm melamine board with medium density board as the base material is more durable and can give full play to the characteristics of panel furniture to resist assembly. The texture of particleboard is relatively loose, and the cost is lower than the former.
Formaldehyde problem
wood melamine sheets itself has little toxicity, is relatively stable, and will not be free of toxicity after curing. Whether the melamine faced mdf used to make furniture pollutes the air depends on the medium density board or particleboard base material used in the melamine board. If the formaldehyde emission of the base material meets environmental protection standards, melamine will not aggravate the material pollution. The melamine faced mdf 18mm has no odor. The odor is produced by inferior medium density boards and coatings using adhesives or additives that contain formaldehyde and other substances. It is not possible to find boards that do not contain formaldehyde at all, but the accumulation of a variety of furniture will easily cause the formaldehyde to exceed the standard after the decoration, so after the decoration, keep ventilation for several months, and wait until the harmful gas in the air reaches the national standard before moving in.
