Wood-based panels of sheet metal class interior finish materials

Wood-based panels of sheet metal class interior finish materials

(1) Plywood
1) plywood Category:
Ordinary plywood with wood veneer into thin slices, then press the odd adhesive layers, layers of fibers perpendicular to the direction of hot glue made of man-made sheet. Our logs are mainly used birch, poplar, ash, pine, wrought wood, pine and some imported logs. Should be an odd number of layers of plywood, according to the number of layers of plywood can be divided into three folders (PCT) board, five folders (PCT) board, seven folders (PCT) boards and nine folders (PCT) board, three clips (PCT ) board, five folders (PCT) board is most commonly used. The thickness of the plywood is 2,7 mm, 3,0 mm, 3,5 mm, 4,0 mm, 5,0 mm, 6,0 mm, etc., from 6mm by 1mm increments from. Thickness of less than or equal to 4mm thin plywood. The most common format size plywood is 2440mmx1220mm marine deck material.

 2) Plywood advantages:
 ① plywood sheet large format, ease of processing; longitudinal and transverse tensile ② sheet, uniform shear strength, adaptability; ③ board formation, shrinkage is small, not Alice does not crack; ④ board has a beautiful grain , is the most frequently used decorative works, the largest number of the plate, the substrate can be done both decorative panels, and can be directly used for decorative panels, can get natural wood texture.

 3) Plywood Scope:
  Plywood for architectural interior wall decoration, but also used to make furniture. Plywood surface into various types of paint can paint can laminating a variety of wallpaper, wall covering, decorative panels can be pasted all kinds of plastic, but also for spraying paint. Principal product is mainly used for high-level architectural decoration, furniture and other special needs products, first-class product for the more advanced architectural features, and high-ranking furniture, all kinds of electrical enclosures and other products. Plywood classification, characteristics and scope of application composite marine flooring for boats.

   (2) Blockboard
   Blockboard, also known Daixinban, is one of the building with the main varieties of decorative wood-based panels. It is a strip of wood core, the outer veneer wood processing wood profiles. Blockboard has a density, deformation, high strength, good dimensional stability, grip nails and so on. Therefore, a home decoration wall, the top of the decoration and wood products essential to the production of furniture. Blockboard intermediate wooden materials are generally poplar, paulownia, fir, willow press, white pine and so on. Quality products plate surface smooth, no unglued, sand injury, indentation, thickness deviation is small, no air core after sawing.

   (3) MDF
   MDF also known as fiber, is a wood fiber or other plant fibers for applying pulse-formaldehyde resin or other synthetic resin under heat and pressure, a pressed sheet. MDF panels than the average density is higher, according to their different densities, divided into high, MDF, low-density boards. Now the market is commonly used MDF. MDF uniform structure, moderate density, high mechanical strength, dimensional stability, deformation, smooth surface, solid edge and good decorative surface properties of the plate, so it can be made into a variety of type faces for manufacture of laminate flooring, furniture, ships and vehicles as well as partitions, walls, doors and other architectural decoration materials. The disadvantage is the higher precision and process requirements, higher cost; because of its high density, it is necessary to use precision saw cutting, not in the decoration scene processing; Besides poor nail holding power. MDF product quality testing can generally be deviations from size, appearance, quality, physical and mechanical properties and formaldehyde emission limits and other four aspects to reflect best deck and patios.

   (4) Particle Board
   Particleboard is made of wood and scrap (wood shavings, sawdust or similar material) or non-wood plant scrap (flax crumbs, sugar cane bagasse, wheat straw, rice straw or similar material) together with adhesive made of hot plates. Particleboard board formation, very solid, high physical and mechanical strength, consistent with the longitudinal and transverse strength; insulation, mold, economic, insulation. Particleboard its honeycomb-like cross-section, hence the name. Advantages: Internal crossover scattered granular structure, good nail holding power; cost cheaper than MDF, and formaldehyde content is much lower than Daixinban, is one of the most environmentally friendly man-made sheet. Disadvantages: quality differences between different products, which is difficult to distinguish; bending and tensile poor; low density, easy to loose. Particleboard press materials, divided into: wood particleboard, bagasse particleboard, particleboard scrap linen, cotton stalk particleboard, particleboard and other bamboo. Divided by the surface condition: No sanding sheet, sanding plate, coated plate, decorative materials decorative panels. Use is divided into: general purpose boards for use in dry conditions, in the dry state using the furniture and interior decoration panels, the structure used in the dry state with a plate structure in the wet state boards for use in dry enhancement structure used by the state board, reinforced structures in the wet state boards for use deck new plastic finishing.
