[0002] Science and technology veneer is a new type of decorative material processed by high-tech means. It is made from ordinary wood as raw material, through a series of complex processes such as slicing, bleaching, dyeing, and recombination. Science and technology veneer can simulate the textures and colors of various precious woods, and even create unique textures that do not exist in nature. It has strong decorative and ornamental properties, with uniform color, beautiful and regular texture, and can provide high-quality decorative effects for furniture, doors and windows, interior decoration, etc. At the same time, it also has good physical properties, such as high strength, good toughness, not easy to deform, corrosion-resistant, etc., and is more durable than natural veneer. In addition, the production process of science and technology veneer is relatively environmentally friendly, can effectively utilize wood resources, reduce the felling of natural precious woods, and meet the requirements of sustainable development. In practical applications, science and technology veneer is widely used in furniture manufacturing, interior decoration, audio equipment, automotive interior decoration and other fields, providing people with a beautiful, practical and environmentally friendly decorative option; When producing science and technology veneer, it is usually necessary to use dried logs for processing. The logs are prone to dropping debris during drying. The debris is flammable and prone to safety hazards.
