Daxinban: scientific blockboard, in the middle of a multi-layered wood sticks sticky composite core, on both sides and then affixed to the thin plate, as the name suggests Daxinban. Advantages: simple processing technology, good nail holding power. Disadvantages: due to a variety of Zamu combined together, the density difference is larger, easy to produce distortion; high water content; high formaldehyde content; can not be used directly, must be done late. Usage: The commonly used processing method is manual single-layer paste veneer or brush mixed oil, paint varnish on the back, such as double-sided stickers are twice as expensive. Environmental testing standards: The amount of formaldehyde released per cubic meter of board should be less than or equal to 150 mg. Uses: Even if it has such defects, in the current home improvement projects, whether it is doors, door covers, window covers, heating covers, or lockers, partition cabinets, etc., are most commonly used as large core boards.
Several types of wood that can replace large core boards:
1. MDF. A kind of medium density fiberboard artificial board, degreased and peeled logs, crushed into wood chips and then high temperature, high pressure molding, high density, so called density board, the surface is often affixed with trimethylene ammonia or veneer and other ornaments surface. Advantages: excellent physical properties, uniform material, there is no dehydration problem, will not be moisture deformation; the surface of the tri-hydrin ammonia surface moisture, corrosion, wear resistance, high temperature and other characteristics, do not require post-processing, formaldehyde content low. Disadvantages: high processing accuracy and process requirements (due to high density, must be cut with a precision saw); poor nail holding power; not suitable for processing at the decoration site; high cost (according to the difference of imported and domestic veneer and thickness of veneer, Each price ranges from 80 yuan to 200 yuan.)
Usage: With large-scale equipment, double-sided simultaneous hot-pressing of tri-hydrogen ammonia finish on a medium density board, tightly attached to the surface of the medium-density board substrate, there are a variety of colors to choose from, must be professional precision equipment Processing, using a special connector to fix, can be disassembled and assembled. Environmental protection standards The formaldehyde emission per cubic meter of board should be less than or equal to 30 mg.
2. Particle board. One type of wood-based panel, which is crushed into pellets after being formed into various pellets, and then bonded by high pressure. Because its profile resembles a honeycomb, it is called particle board. Advantages: The inside is a granular structure with cross-stitch structure, so it has good nail holding power, good lateral load bearing capacity, and a lower manufacturing cost than the medium density board. Although the formaldehyde content is higher than the medium density board, it is much lower than the large core board; the price Relatively cheap (according to the difference in imports and domestic finishes and thickness of the finishes, each price ranges from 60 to 160 yuan). Disadvantages: Due to the fact that the method of manufacture is easy, the quality varies greatly, and it is not easy to distinguish. The flexural and tensile properties are poor, and the density is loose and loose.
Usage: The surface is often double-laminated with a tri-hydrin-based veneer. After the edge-sealing treatment, the appearance is the same as that of the medium-density board; it needs to be cut with precision equipment, and is also assembled with a dedicated connector. It is removable. Environmental testing standards: The amount of formaldehyde released per cubic meter of board should be less than or equal to 40 milligrams.
