Description

Wooden splint and preparation method thereof

Technical Field

The invention relates to the field of processing of wooden splints, in particular to a wooden splint and a preparation method thereof.

Background

The wood plywood in the market is various. Wooden cleats also have many of their own advantages: the wood is easy to process. The wooden sandwich plates are mostly subjected to tenon joint, nail joint and cementation and various metal connecting pieces; or bending and compressing after steaming. The wood has a higher strength-to-weight ratio than common metals, i.e., the wood is light and strong. The air-drying material is a good thermal and electric insulating material. The handle of the appliance is made. The wood has natural beautiful patterns, luster and color, and can play a special decorative effect. The wood has the functions of absorbing ultraviolet rays and reflecting infrared rays. The wood has good acoustic effect. The wood is elastic plastic material, has certain jade when damaged, gives people a sense of safety, and can be used as a sleeper. The wood can adjust temperature and release moisture, and has good environmental characteristics.

However, at the same time, wood has some disadvantages: dry shrinkage, wet swelling, and anisotropy. When the moisture content of the wood is changed below the saturation point of the fiber, the size of the wood is changed. Due to the anisotropy, the wood has different dry shrinkage and wet expansion in all directions, which may cause the defects of cracking, warping and the like of the wood. Wood is susceptible to decay and attack by insects. The wood is used as coastal aquatic building materials, wooden ships and the like, and is often damaged by marine drilling animals. Wood is easily burnt. The variability of wood is large, and different tree species, different producing areas, different climates and different parts (such as heart wood, early and late wood, young wood and mature wood) are different. Wood has natural defects such as: scabs, insect eyes, etc.

And the wooden plywood made of wood has a great variety.

The natural, environment-friendly and healthy wooden splint can show the beauty of nature and originality. The wood plywood is rich and not weak, and the natural wood color of the wood plywood is analyzed from the color. The original wood color wooden splint is natural and has no chemical pollution, which is a healthy fashion choice and accords with the psychological needs of modern urban people for advocating the natural world.

However, the main problems of the existing wooden plywood are that the plywood is easy to deform due to the change of the moisture content, so that the plywood cannot be directly irradiated by sunlight, the indoor temperature cannot be too high or too low, and an excessively dry and humid environment is not suitable for the wooden plywood. In addition, the components of the wooden splint are usually combined by adopting a tenon structure and an adhesive, and the finished product can not be disassembled generally and is inconvenient to carry.

Because the textures and the hardness of each jointed board strip are different, the thicknesses of the strips cannot be consistent even though the fixed-thickness sander is used, and the strips on the surface of the plate are uneven. After painting, the uneven phenomenon of each batten is more obvious.

If the transverse splicing quality is poor, the brain is recovered to splice obvious transverse splicing glue seams. If the transverse splicing strength is not enough, cracks are easy to appear at the glue seam. Therefore, in the conventional wooden plywood, the height of the battens and the glue lines between the battens can be observed when the painted surface of the furniture is seen in the direction opposite to the light. The phenomenon is small due to the exquisite material selection and scientific process, but cannot be avoided fundamentally.
