Q:What is plywood?

It is commonly known as plywood plywood, natural wood boiled softening, use of wood along the ring spin into large slices (veneer) in general 2.7mm thickness 20mm and above, according to the principle of symmetry, generally consists of three or more layers of a millimeter thick thin veneer, wood fiber layer adjacent to each other in the vertical blank, after drying, imposition, glue, hot pressing, glued into three or more layers (usually 3 - odd layer, 13 layer plate material). High quality product surface is smooth and smooth, without degumming, sand injury, press injury, no obvious color difference, no stains, good size processing accuracy, small thickness deviation, bonding strength 0.7Mpa, moisture content 6 - 14%. Usually used as substrates and panels, they can be used in building, interior decoration, furniture manufacturing, shipbuilding, packaging and other industrial products.Buy Plywood first, look at environmental protection. Depends on whether the release of harmful gases in line with national standards, especially the release of formaldehyde free glue is excessive. For these professional too strong things, most consumers may not clear, and can not be measured, so it is a shortcut to see whether manufacturers have environmental labeling products in china. Because to pass the certification, must be based on quality, environmental protection double standards as the premise.Next, look at the material. The price of different tree species is different. Consumers can choose different kinds of materials according to different demands. At present, the market is full of a large number of low price of Eucalyptus core plywood. In fact, this is the poplar core board made of surface coloring treatment, so the appearance of the board is basically the same, but the quality is very different. In fact, the core board, whether it is component or hardness, toughness, are higher than poplar core board, consumers should carefully identify when buying, so as not to be fooled.

Q:What is an offset press? And what are the machines for printing paper?

Q:What kind of glue does bamboo plywood use in general?

Water soluble phenolic resin adhesive is usually used. Water soluble phenolic resin adhesive is one of the most important types of insoluble phenolic resin adhesive. The component of free phenol content is low (usually <2.5%), less harm to human body, and a water soluble phenolic resin can save a large amount of organic solvent, easy cleaning in coating operation, so it is widely used in wood processing industry. The binder is mainly used for bonding wood.Bamboo plywood is made of bamboo with groove and equal thickness bamboo as its unit, and bamboo is made by rolling and planing. Bamboo plywood can be used as an ordinary structural board, and also can be used as the floor of a car by the length and surface treatment of sheet metal

Q:What's the market price of bamboo plywood?

Bamboo plywood is made of bamboo material as the main structure and filling material! Because of the high hardness, bending resistance and compressive resistance of bamboo plywood, steel formwork has been replaced in many use areas! Because bamboo is easy to cultivate, quick forest trees, three to five years will be cut down, can replace wood, therefore, the State Forestry Department policy supports the development of wood-based panels with bamboo as the main materials, has replaced the use of wood plates in a lot of places! What specifications are required for different thicknesses?
