There are many reasons that lead to the bubbling of plywood, it may be that the raw material is not qualified, the quality is not good, the surface smoothness of the substrate is poor, it is easy to cause the phenomenon of bubbling of multi-layer board finished products; It is also possible that the poor quality of the veneer material, some materials do not have the waterproof performance, use will be infiltrated into some foreign air, this should not occur. Or is the processing technology is not mature, the process is not standard, if the plate and veneer is not in place, then bubble appears is very common. Improper use of the end of the plywood factory in Guangxi will also cause the products of the multi-layer Plywood factory to blister. Even if the temperature and humidity are in an unsuitable situation, this situation will also happen. We need to know more about it, to make the panels work better.

Plywood also known as splint line commonly known as thin core board. Made of three or more layers of one-millimeter veneer or sheet adhesive hot-pressed. Is currently the most commonly used materials for handmade furniture. SPLINTS are generally divided into 3 cm, 5 cm, 9 cm, 12 cm, 15 cm and 18 cm (1 cm is 1mm) . And, of course, 21% and 25% , which are used by a lot of factories.

Plywood is by the log into veneer or wood planing thin wood, and then glued into the three or more layers of thin board. It is usually made of an odd number of veneers, with the fibers of the adjacent veneers arranged perpendicular to each other. Therefore, there are Sanhe, Wuhe, Qihe and other odd-numbered layers of plywood.

From the structural point of view, the plywood of the outermost veneer known as the surface, the front of the surface known as the panel, it is a better quality of veneer. The opposite side of the surface is called the backplane, followed by the quality of veneer. And the veneer of inner layer is called core board or medium board, with the worst quality veneer composition.

The plywood produced has the following characteristics: 1. All the advantages of plywood as a stamp-collecting natural wood, such as its light weight, high strength, beautiful texture, insulation, etc. , it can also make up for some defects of Natural Wood, such as knot, small size, deformation, great difference of vertical and horizontal mechanics, etc. . Rational utilization of plywood production capacity for logs. Since it has no Sawdust, 1 cubic metre of plywood can be produced from 2.2-2.5 cubic metres of logs, which can be used instead of 5 cubic metres of logs sawn into sheets, and 1.2-1.5 cubic metres of residue can be produced from 1 cubic metre of plywood products, this is the production of medium-density fiberboard and particleboard relatively good raw materials.

Plywood has many advantages, such as small deformation, large width, convenient construction, no warping and good tensile properties. Therefore, this product is mainly used in furniture production, interior decoration, residential construction of various plates, followed by shipbuilding, car manufacturing, various military, light industrial products and packaging and other industrial sectors only.

Plywood according to use is divided into ordinary plywood (suitable for a wide range of uses of Plywood) and special plywood (to meet the special purpose of plywood) . The quality requirements of plywood include appearance grade, specification and size, physical and mechanical properties. Appearance Grade, size, physical and mechanical properties of the three inspection are qualified to judge the product is qualified, otherwise the judgment is not qualified. When plywood leaves the factory, it shall have a certificate of quality from the Quality Inspection Department of the factory, indicating the type, specification, grade, bonding strength and moisture content of the plywood.
