What is melamine Board,melamine mdf,melamine plywood?

Melamine board is also called double-trimmed board, and some people call it one-off board. Its substrate is also particle board, made of substrate and surface bonding, the surface veneer mainly has two types of domestic and into the product, because it is fire-resistant, anti-abrasive, waterproof immersion treatment, the use of the effect is similar to the composite wood flooring.

1. Introduction

The decorative paper is colored melamine sheets soaked in melamine solution, and then pressed on after hot pressing. So, do furniture moisture-proof board is generally called waterproof melamine board, melamine is a solution does not contain formaldehyde, is environmentally friendly, so that posting up not only will not cause 2 pollution, but will reduce the release of the substrate inside, this treatment method is recognized by everyone, most of this in doing. However, this surface treatment is also divided into good and bad, because the price of melamine solution is almost 10 times the price of other glue, there are many people in the solution mixed with Leyland glue of melamine covered mdf, this is not environmentally friendly, so the board is also divided into full melamine and half melamine board, this non-professional bad recognition, the main look at the surface through the bottom (new, do not take the old look). There are also melamine veneer press of different steel plates, can make the white mdf home depot surface effects, divided into light, hemp (coarse hemp, fine hemp and velvet hemp), relief surface (large relief and small relief). Hemp and embossed surface than the glossy surface expensive 2-3 RMB, but generally used for cabinet doors, the general cabinet body or glossy white melamine boards for sale.

Melamine laminated mdf, referred to as melamine board, the industry prefers to be called ecological board, the full name is 6mm melamine faced mdf impregnated with adhesive film paper finish man-made board. The paper with different colors or textures is soaked in melamine resin adhesive, and then dried to a certain degree of curing, it will be laid on the surface of particle board, moisture-proof board, MDF, plywood, joinery or other hard fiberboard, the decorative white coated mdf made by hot pressing. In the production 6mm melamine process, it is generally made by combining several layers of paper, the number of which depends on the usage. Melamine board is not a new product, the name fancy does not mean that the product is fresh. This kind of board has long been produced in China, initially used to make office furniture such as computer desks, mostly monochrome board, with the popularity of panel furniture in the home, it gradually became the preferred manufacturing material of various furniture factories, the surface color and pattern is also more. The market for panel furniture uses both imported and domestic large melamine sheets.

According to the internal fiber form can be divided into melamine particle board and melamine density board two; melamine particle board substrate is the wood into particles and wood chips, by, reorientation arrangement, hot pressing, gluing dry formation; melamine mdf board prices substrate is the wood into sawdust, by reorientation arrangement, hot pressing, gluing dry formation. The difference between the two is that: the particle board is strong and has strong ceiling absorption capacity, while the density board is relatively weak, and of course the latter is cheaper.

2 Performance

The performance of melamine decorative board.

It can be used as veneer of various mdf and melamine boards and woods, with high hardness, wear resistance and good heat resistance. General chemical resistance, resistant to general acid, alkali, grease and alcohol and other solvent abrasion and smooth surface, easy to maintain and clean.

Melamine board 30mm has the excellent performance that natural wood cannot have, so it is often used in interior architecture and various furniture and cabinet decoration.

Melamine board is a wall decoration material. Some people use melamine board to fake laminate flooring for floor decoration, which is not suitable.

Common specifications: 2440mm×1220mm, 2-30mm thick.

3 Composition

“Melamine” is one of the resin adhesives for the manufacture of such gloss melamine board prices, with different colors or textures of paper dipped in resin, dried to a certain degree of curing, it will be laid on the surface of particle board, MDF or rigid fiberboard, hot pressed and made of the installed board, the standard name is melamine-impregnated film paper-finish 3mm melamine faced mdf. Called its melamine board is actually said to be part of its finish into.

Generally divided into surface paper, decorative paper, covering paper and bottom paper and other components.

① Surface layer mdf with white laminate, is placed on the uppermost layer of the decorative board, play a role in protecting the decorative paper, so that the surface of the board after heating and pressing is highly transparent, the board surface is hard and wear-resistant, this paper requires good water absorption, white and clean, transparent after dipping glue.

② Decorative paper, that is, wood grain paper, is an important part of the decorative board, with a background color or no background color, by printing into various patterns of decorative paper, placed under the surface layer of paper, mainly to play a decorative role, this layer requires paper with good covering power, the

Impregnation and printing properties.

③ Covering paper, also called titanium white paper, generally in the manufacture of light-colored decorative maple melamine sheets, placed under the decorative paper to prevent the bottom layer of the main function is to cover up the color spots on the surface of the substrate. Therefore, a good covering power is required. The above three papers are dipped in melamine resin respectively.

④ Base layer paper, is the base material of melamine mdf 18mm, the board plays a role in mechanical properties, is dipped in phenolic resin glue by drying and into, production can be determined according to the use or decorative board thickness of a number of layers. In the selection of such board furniture, in addition to color and texture satisfaction, you can also identify the quality of appearance from several aspects. There are no stains, scratches, indentations, porosity, color gloss is uniform, there is no bulging phenomenon, there is no local paper tear or defective phenomenon.

4 Advantages

The advantages of this sheet are: flat surface, not easy to deform because of the same expansion coefficient on both sides of the sheet, bright color, more wear-resistant surface, corrosion resistance, and economic price.

5 Differences

The melamine board furniture on the market for the family is mostly based on MDF and particle board, compared to the performance of the joinery board is better than the first two. Blockboard has uniform internal structure, high bonding force, small deformation, good surface flatness, and strong nail holding power. Therefore, the 3mm white melamine faced mdf with joinery as the base material is more robust and durable, and can better play the characteristics of the board furniture to resist assembling. The texture of white melamine board 15mm and particle board is relatively loose, poor nail grip, lower cost than the former.

6 Sealing edge cracking

Melamine sheets lowes makes the appearance of furniture strong, printed with color or imitation wood grain paper itself is fragile, in the melamine board transparent

After soaking in melamine resin to form the film paper to be much harder, this film paper and the substrate hot pressed into one has a very good performance, with its furniture made without paint, the surface of the natural formation of protective film, wear-resistant, scratch-resistant, acid and alkali resistant, hot, pollution-resistant. Consumers in the selection of such board furniture, in addition to taking into account the color and texture satisfaction, but also from several aspects to identify the quality of appearance. There are no stains, scratches, indentations, porosity, color gloss is not uniform, there is no bulging phenomenon, there is no local paper tear or defective phenomenon, etc.. If the phenomenon of cracked or broken veneer, can be repaired by the following methods.

First put a wet cloth on the broken place, then put a hot iron on the wet cloth to force moisture into the veneer, so that the veneer becomes very tough and not easy to break. This can first scrape the old glue clean, and then apply a layer of emulsion glue on the base wood, and then apply a layer of new glue on the reverse side of the loose veneer, compact, and leave the glue to dry completely.

7. Environmental protection

Melamine board is light, mildew-resistant, fire-resistant, heat-resistant, shock-resistant, easy to clean, renewable, fully in line with the established policy of energy saving and ecological protection, so the industry is also known as ecological 5×10 melamine sheet. In addition to solid wood furniture, all kinds of high-grade panel furniture have melamine board participation. The addition of melamine board in the high-end closet can effectively prevent environmental pollution caused by formaldehyde and urea-formaldehyde resin used as a preservative, and melamine board can also replace wood panels and aluminum panels to make mirror, high wear-resistant, anti-static, embossed, metal and other finishes.

E1 melamine board, referred to as melamine board, is a decorative board made by hot pressing it on the surface of particle board, 22mm melamine moisture-proof board, MDF or rigid fiberboard. In the production process, it is usually made by combining several layers of paper, the number of which depends on the usage.

The performance of MDF is better than the latter. The internal structure of MDF is uniform, the bonding force is greater than that of particle board, the deformation is small, the surface flatness is good, and the nail holding force is strong. Therefore, the white coated mdf board as the base material is more robust and durable, and can better resist the characteristics of panel furniture assembling. The texture of particle board is relatively loose, poor nail grip, lower cost than the former

8 .Formaldehyde problem

Regardless of what kind of board, in the manufacturing process are essential to use glue, so after forming the 19mm melamine board will release free formaldehyde, but under a certain concentration is harmless to humans, consumers in the recognition of the quality of the board at the same time, the most important concern is the furniture used in the formaldehyde release of the board. According to national standards, the formaldehyde emissions per 100 grams of particle board should be less than or equal to 30 mg; E1 level MDF per 100 grams, formaldehyde emissions less than or equal to 9 mg; E2 level MDF, formaldehyde emissions between 9 mg and 40 mg. In other words, formaldehyde emissions higher than the above standards of board furniture, should not be purchased. Consumers can ask the business to produce a test report of the furniture substrate to identify whether this indicator meets the requirements.

Melamine itself is very toxic, relatively stable, and textured melamine sheets will not be free of toxicity after curing. The air pollution of melamine panels for furniture production depends on the substrate used for melamine panels or particle board, if the amount of formaldehyde released from the substrate meets environmental standards, melamine does not aggravate material pollution, melamine boards b&q do not have any odor, the odor is the lesser quality of MDF, paint using adhesives or additives containing formaldehyde and other substances emitted.
