MDF is medium density fiberboard a product of composite wood. This product is made from waste wood fibers impregnated with resin under the influence of heat and pressure glued on the board. Ability of coating made from this product beautiful and durable plates, especially in places like the kitchens. MDF is very convenient for kitchen cabinet door and cornice, because it is smooth and uniform, has not disadvantages of wood, does not warp, with a compact, smooth, firm and without knots properties easily machined.
MDF is stronger and denser than chipboard. The reason is that it is made of tiny particles that are not easily recognizable. MDF is painted and then the opposing surface changed into very smooth. Because MDF has no grain it can be cut, drilled, bend and was sanded without damaging the surface.
MDF has many advantages, its surface is extremely smooth because the wood fibers used in its manufacture. Its texture is very smooth and has a quality that makes it hard to "discrete" means that when sawed off rough-cut edges will be to be replaced by a smooth edge.
Standard MDF shows minimum reaction against the moisture in high humidity areas such as the kitchen or bathroom cabinets, not swing or not swollen.
To coating MDF, color, natural veneer (wood), synthetic varnishes and laminates are used.
MDF with wood coatings, only use in cases where there is no risk of moisture and heat. Wood veneers generally very sensitive to moisture, heat, impact, abrasion. Sheet coated MDF After pressing, will remain at least 8 hours to cool. The beauty of natural wood veneer will attract consumers but the major disadvantages of these natural coatings are not resistance to moisture, heat, chemicals, etc.
MDF Furniture, cabinets, and doors with wood veneer would only place in safe and dry locations.
HDF High Density Fiberboard is made of wood fiber or other plant fiber adding urea formaldehyde or other synthetic resin with the process of compressing in pressurized heating conditions.
With its excellent physical properties, High Density Fiberboard also have all the ad vantages of Medium Density Fiberboard and is widely used in indoor and outdoor decoration, office and high-grade furniture, stereos, interior decoration of senior cars and electronics industry.
It also serves as good production materials for antistatic flooring in computer rooms, wall defense clapboard, burglarproof door, wall panels, and shelves and so on. It is also fine packaging material. What’s more, it is widely used in interior decoration in place of high-class hardwood and can be directly processed into composite floor, strengthened wood flooring etc.
With its smooth surface, solid texture and long life, it is well received by the users.
Chipboard or Neopan, is a common product that is made from resin coated particles of softwood. Though it is denser than conventional wood, it is the lightest and weakest type of fiberboard. These plates can be coated and uncoated with natural or synthetic materials. Chipboards with coated surfaces is called "MFC” or melamine faced chipboard. Chipboard is in series of wood-based industries and made from wood’s wastages and other cellulosic materials are evenly spread over a flat plate and heat bonded together under high pressure presses.
The chipboard are divided into several parts according to their cutting shapes a plywood board, plywood, non-specific and multiple layers which are manufactured by roller presses.
Another group of Neopan is produced by moulding press. The main difference between these two kinds of presses is in the form of the form of the press’s pallet which forms the board by embossed, sunken, curved, and lineal.
Chipboard is divided into four categories based on the surface:
* Plain chipboard which is found in sanded form applications where exposed as false ceilings and closets
* Chipboard coated with natural (wood) is used for decoration and aesthetic surfaces, such as interior design, home desks and cabinets. To do this, the wood veneer such as walnut, beech ... is used.
* Chipboard coated with synthetic paper impregnated with synthetic adhesives simple, colorful and with the inspired designs of wood planks in environments where heat and humidity are high, such as walls, bathrooms and locker rooms, restaurant tables, kitchen cabinets
* Melamine face chipboard coated by an impregnated moisture and heat resistant decorative finish found either side of the board, often seen in white but also in hundreds of colours and wood grains in different textures and sheen levels from matt to gloss available. There are other types of chipboard available including flooring grade, moisture resistant, melamine veneered, plastic veneered (used on worktops), white melamine coated as well as other colours including wood grains (as used in kitchen cabinet construction) and real wood veneered (used on cabinet doors and laboratories services).
(Wood Plastic Composites) WPC or wood - plastic composite is a product that is made in any shape of woods and thermo plastics that is commonly known as Poly-Wood.
Varied products in various industries come from the composite products such as construction (frame, profiles, doors components, windows, cornice, fences and shelving), automotive (car interior), decoration (furniture, cabinets and kitchen counter), railroads (railways sleepers and rails), shipbuilding (aboard ships, docks ports) are used.
These composites are highly resistant and safe to heat, moisture and fungus and insect infestation.
Poly-woods in experience gained compounds show similar responses to fire. Another distinguishing feature of composite plastic - wood is environmentally friendly because it has a negligible waste and the waste recycling and reuse.
These composites are not containing any formaldehyde gas or volatile organic compounds. Such waste is not hazardous materials they can be discharged using standard methods.
Poly-woods are good strength and durability. Plastic is strained under the temperature, while wood is expanding at different humidity. Add wood to plastic reduces the linear expansion to fifty percent and further. This product has a very high hardness, Combination of plastic and wood ready this composite to use for building applications that require strength and stiffness. Adding wood fiber to plastic pores can make it harder to twice and sometimes three times.
