Description

Dampproofing plywood

Technical Field

The utility model relates to a plywood technical field specifically is a dampproofing plywood.

Background

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.

The existing plywood is a three-layer or multi-layer plate-shaped material which is formed by rotationally cutting wood sections into single plates or slicing wood squares into thin wood and then gluing the thin wood with an adhesive, but the strength of the plywood is lower, and the interior of the plate is easily affected with damp. Therefore, the utility model provides a dampproofing plywood to solve the problem that proposes in the above-mentioned background art.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a dampproofing plywood to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a dampproofing plywood, includes offset plate and lower offset plate, the junction of going up offset plate and lower offset plate is equipped with the ripple limit, and bonds between going up offset plate and the lower offset plate, goes up the offset plate and sets up the through-hole that runs through with the junction of lower offset plate, is equipped with the drier in the through-hole, the upper surface of going up the offset plate bonds and has last glass fiber screen cloth, and the upper surface of going up glass fiber screen cloth bonds and has last dampproofing membrane.

As a further proposal of the utility model, the upper surface of the upper moisture-proof film is bonded with the upper surface plate, and the surface of the upper surface plate is smooth.

As the utility model discloses further scheme again, the lower surface of offset plate bonds and has lower glass fiber screen cloth.

As the utility model discloses further scheme again, the lower surface of lower glass fiber screen cloth bonds and has lower dampproof membrane.

As a further proposal of the utility model, the lower surface of the lower moisture-proof film is bonded with the lower surface plate, and the surface of the lower surface plate is smooth.

As a further aspect of the present invention, the drying agent is lime powder.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses in, the setting on ripple limit on last offset plate and the lower offset plate has increased the area of contact between last offset plate and the lower offset plate, effectively improves the fastness of plywood, utilizes glass fiber screen cloth and lower glass fiber screen cloth, can improve the intensity of plywood.

2. The utility model discloses in, go up the inside moisture of plywood of drier ability effective absorption plywood in offset plate and the lower offset plate, keep the inside dry of plywood, go up the dampproof membrane and dampproof membrane down, can play better dampproofing effect.
