MDF fiber board - in Medium Density Fiberboard in fiber board is a kind of Density board, including long fiber board and fiber board with wood fiber or other plant fiber as raw material, after the break, fiber separation, drying applying urea-formaldehyde resin or other suitable adhesive, then through hot pressing after a man-made plank. Its density is generally in the range of 0.5 0.8 g/cm 3, generally for 5-30 mm thickness. A, physical and mechanical properties due to the plate uniform fibre, high bonding strength between the fiber, therefore, its static music intensity, planar tensile strength, elastic modulus, good grip geometric chipboard screw force. Moisture absorption, water absorption performance, thickness expansion rate is low. Second, decorative performance due to the medium density fiberboard (MDF) surface level off, smooth, easy to adhesive sliced veneer material such as two sub-companies named seaport and tissue paper, and is advantageous for the finishing and coating saving.Three, the processing properties of medium density fiberboard (MDF) can produce from a few millimeters to a few millimeters thick plate, can substitute for arbitrary thickness of wood, timber, and has a good mechanical processing performance, sawing, drilling, slotting, camphor, sanding process and sculpture, the edge of the plate can press any shape processing, smooth surface after machining. Due to its excellent performance and is reasonable and comprehensive utilization of timber
The medium density fiberboard (MDF) is currently one of the most promising product. Its features are: 1. The internal structure of uniform, moderate density, good dimensional stability, deformation small, moderate physical and mechanical properties. 2. The surface level off is smooth, the machining performance is good, can paste on the plane cut two sub-companies named seaport or decorative pattern is novel, beautiful, so loved by people in the home decoration, often used in making furniture, partition and so on. The following aspects should be paid attention to when choosing medium density fiberboard (MDF); 1. Watch its thickness and density is uniform and edges have damaged, have the phenomenon such as delamination, beat, carbonation, presence of loose parts. 2."When a conditional, but saw a small piece of medium density fiberboard (MDF) on the water temperature is 20 ℃ water soak for 24 hours, the concept of change, the thickness of observed surface if there is a small bulge. Thickness change is big, the plate has a small bulge that surface water proofing property is poor. 3. Choose to release a quantity to low medium density fiberboard (MDF), when the choice in the sense of smell smell, should choose to stimulate flavor small medium density fiberboard (MDF), because the smell, the greater the formaldehyde release a quantity to the higher, the pollution caused by the greater. Density board, also known as fiber board, wood fiber or other plant fiber as raw materials, applying pulse aldehyde resin or other applicable adhesive made from man-made plank. According to the amount of different, divided into high density board, MDF, low density board
