Selection of sheet metal

- Feb 22, 2019-

The selection of the board depends on the environmental protection and environmental protection. The amount of formaldehyde released directly from the building materials must be less than or equal to 1.5 mg per liter.

1. Blockboard: The moisture-proof effect is good, but it can't be directly painted. The middle of the wood-washing board is a core made of natural wood strips. The two sides are glued with very thin veneer, which is one of the most important materials in the decoration. . Can be used for furniture and wooden doors and door covers, curtain boxes, etc. It is advisable to select a blockboard with a gap of 2MM between the inner woods. The large core board is divided into 3, 5, and 9 PCT plates according to the thickness, and everyone can choose according to the pressure and strength to withstand. When picking one, look at the appearance: one side of the large core board must be a whole piece of wood, and the other side only allows one seam. The surface must be dry and clean. In addition, the large core board can not be used as a panel, and a layer of plywood should be attached as a panel, otherwise there will be problems such as paint blistering.

2, solid wood board: integrated board, not easy to deform, using high quality imported large diameter logs. Intensively processed, this board has superior environmental performance, and it is one-eighth of the amount of formaldehyde allowed in the large core board, and the price is higher than that of the high-grade large core board. Plates made of solid wood such as American spruce can be directly painted and painted. It is necessary to save a process compared to the large core plate. Finally, the construction cost will be flat.

3, particle board is the main material of the current cabinet. The MDF is pressed and formed with powdered wood chips, which has good flatness but poor moisture resistance. In contrast, the nail holding force of the MDF is worse than that of the particle board. If the screw is loosened after screwing, due to the strength of the MDF. Not high, it is difficult to fix, so it is rarely used for cabinets.

4, the facing three plywood is cheap and cheap, also called three plywood and plywood, the different layers are called different. It can also be called 3-9 cents for half a year. Its pros and cons mainly depends on raw materials. The main use in the home decoration is the veneer plywood, which has already attached a very thin solid wood veneer to the three plywood in the factory. The veneer plywood is easy to use and the price is cheaper than the one that buys the veneer to make the construction team stick.

5, veneer: the same effect as the manufacture of solid wood. It is a veneer that is cut with high-grade wood with obvious wood grain. It is very thin and the thinnest is only 0.3MM. Thick is also 2-3MM. The color of common veneer is from shallow to deep. There are more than ten varieties of cherry, maple, white oak, red oak and walnut. The price is high. Large-scale use is best to buy directly facing the plywood

The artificial board used for decoration is a product of secondary processing of ordinary artificial board through the veneer. According to the decorative materials, there are many types of natural wood veneer wood-based panels, plastic veneer wood panels, and paper-finish wood panels.

Paper-finished wood-based panel This panel is a special paper-based finish material with wood-based or other patterns on the surface of wood-based panels. Its various surface properties are slightly worse than plastic veneered wood-based panels. Commonly available are Polaroid plates, ornate plates.
