Density board, also known as fiberboard, is a man-made board made of wood fibers or other plant fibers with the application of urea-formaldehyde resin or other applicable adhesives. According to its amount, it is divided into high density board, medium density board and low density board.
Density board is a good material for making home furniture in foreign countries due to its soft texture and impact resistance, and also easy to reprocess, but due to ?
The national standard on high density board is several times lower than the international standard, so the quality of the use of density board in China has yet to be improved.
Medium and high density board (MDF-Medium? Density? Fiberboard), according to national standards GB11718-89: wood fibers or other plant fibers as raw materials, the application of aldehyde urea resin or other applicable adhesives, made of density in the range of 0.50 ~ 0.88 Board, known as medium and high density fiberboard.
High-density board than particle board poor grip, screw tightening, if loose, due to the strength of the density board is not high, it is difficult to fix. Moreover, now furniture more use high density board, and poor quality high density board furniture, the content of formaldehyde is very high, the human body is also very harmful.
