Description

Multilayer plywood of LVT veneer

Technical Field

The utility model relates to a plywood technical field specifically is a multilayer plywood of LVT veneer.

Background

Plywood is a three-layer or multi-layer plate material made up by using wood segments and making them be rotary-cut into single board or sliced into thin wood and using adhesive to make them be glued together, and usually using odd number of layers of single board and making the fibre directions of adjacent layers of single board be mutually perpendicular. The plywood is one of common furniture materials, is one of three large plates of an artificial plate, and can also be used as a material for airplanes, ships, trains, automobiles, buildings, packing boxes and the like. A group of veneers are typically assembled and glued perpendicular to each other in the direction of the adjacent layers of wood grain, and the skins and inner sheets are typically symmetrically disposed on either side of the center layer or core. The glued veneer is pressed into the wood grain board blank by the criss-cross matching of the glued veneer according to the wood grain direction under the condition of heating or not heating. The number of layers is generally odd, and a few are even. The difference of physical and mechanical properties in the longitudinal and transverse directions is small. The types of plywood commonly used are plywood, plywood and the like. The plywood can improve the utilization rate of the wood and is a main way for saving the wood. Typical length and width specifications are: 1220X 2440mm, and the thickness specification is generally: 3. 5, 9, 12, 15, 18mm, etc. The main tree species are: beech, cinnamomum camphora, willow, poplar, eucalyptus, and the like. In order to make the plywood structure conform to the two basic principles, the number of layers should be odd. Therefore, plywood is usually made of three layers, five layers, seven layers and other odd number layers. The name of each layer of the plywood is: the surface veneer is called a surface veneer, and the inner veneer is called a core veneer; the front surface board is called a panel, and the back surface board is called a back plate; in the core board, the core board in which the fiber direction is parallel to the face board is called a long core board or a middle board. The face plate and back plate must be facing closely outward when the cavity platen blank is assembled.

The multilayer plywood that is used for the LVT veneer now prevents fires, waterproof performance is lower, leads to the core to go milden and rot, and flame retardant efficiency is poor, and the potential safety hazard is great when running into a fire.
