MDF (medium-density fibreboard) is an engineered wood product made from wood fibers collected using a defibrillator to break down hardwood and softwood. Waxing and resin adhesive are then used to adhere the wood fibers together. High pressure and temperature are used to turn them into panels. The resultant smooth wooden finish has no dark wood and resembles particle board in many ways. However, particleboard made of MDF is slightly more durable.
Peeler logs make fiberwood, and rotating wood logs across their horizontal axis peels thin layers from them. To make a plywood panel, the sheets of fiberwood obtained from this procedure are cut to the necessary proportions, dried, repaired, glued together, and cooked at 140 °C (284 °F) at 1.9 MPa (280 psi). Fibrewood may or may not be smooth and suitable for visually appealing interior wood components, depending on the grade. For the kitchen cabinetry, some grades of wood can be painted and made to appear attractive.
MDF (also known as medium-density fibreboard) is a fine wood chip-based engineered wood product. Fibreboards of the same thickness are made from felled wood or wood scraps (chips or circuits), which are cut into small fibers (chips) when exposed to high water and fed to the refiner’s revolving segments. All MDF board refined material is immediately sent to the drier for glue application.
The difference between particleboard and MDF chips is comparable to that between meat grinders and mixer goods. Lignin and wax are used to bind wood particles together (paraffin). As a result, MDF is a particularly environmentally friendly material.
MDF products can be placed in environments with an average humidity level of 80%, compared to 60% for wood products.
Benefits
MDF products can be placed in environments with an average humidity level of 80%, compared to 60% for wood.
MDF/HDF is a machine-able, manufactured product with strong structural integrity and environmental compatibility. It has several important advantages, including improved dimensional stability and shape adaptability.
The main advantage of MDF is the ideal relationship between thickness and hardness: thickness can range from 4 to 22 mm. Many door frames with MDF boxes and casings have recently surfaced, with high-cost wood species covering them. MDF boards are easy to handle since their surfaces are flat, smooth, uniform, and dense.
MDF/HDF is commonly used in the manufacture of furniture, doors, and laminated flooring.
Fibreboard is made by pressing wood particles together with a binding agent and then shaping the mixture into a sheet. Any reduced wood type, both softwood and hardwood, can be used to make particleboard. The density, shape, and size of wood and the amount of the binding agent all influence particleboard’s useful properties.
There are particleboards with one, three, and five layers with extremely low (350-450 kg/m3), low (450-650 kg/m3), average (650-750 kg/m3), and high (700-800 kg/m3) density. Fibreboard is not suitable for high-moisture environments.
Particleboard is a common material for cupboard items, home décor, roof and barrier constructions, and other applications.
Waterproof, robust, and simple to handle. Particleboard is machined (cut, pierced, milled, etc.), glued, and painted, and it firmly “holds” nails and screws. Another advantage of particleboard is its low cost. As a result, fiberboard is the most extensively utilized material for making low-cost furniture: particleboard makes up the bulk of office furniture.
Particleboard even outperforms natural wood in terms of physical-mechanical features: it expands less than wood material, is less explosive, does not warp, and has thermal and acoustic capabilities.
Board of Woodfibre
Hot compression of a uniformly cut wood mixture saturated with epoxy polymers, with the addition of specified additives to the mass, produces wood fibreboard. Pulverized wood chips are used to make wood fibreboard. Antiseptics, paraffin, colophony (to boost waterproofing ability), artificial resin (to increase board strength), and antimicrobials are applied to the wood combination to improve the qualities of fibreboard.
Woodfibre board, like MDF, is formed from crushed dust, but in the instance of Woodfibre board, the wood grains are steamed before being crushed.
The following are the different varieties of Woodfibre boards:
• Additional (density – 950 kg/m3);
• Hard (850 kg/m3) and semi-hard (400 kg/m3);
• Insulating-finishing (250 kg/m3);
• Insulating (up to 250 kg/m3).
Humidity drops are not a problem for Woodfibre board. Woodfibre board is used for the backsides of most cabinets and cupboards, and door bottoms. (Instead of Woodfibre board, plywood is used to make the most expensive furniture).
