A multilayer transparent wood prepared by laminating two kinds of tree species

Abstract

Transparent wood (TW) is a new material with a certain light transmission performance, which can be widely used as new energy-saving material. However, the application and development of TW are limited by material and thickness. In this work, the representative species of softwood and hardwood were selected for lamination. After chemical treatment, the lignin in natural wood was removed, and then the epoxy resin with a similar refractive index to the cell wall was impregnated in vacuum. By using the viscosity of epoxy resin itself, the single-layer materials could be effectively laminated together to prepare a new type of multilayer transparent wood (MLTW). By testing the optical properties, mechanical properties. and surface properties of MLTW materials, we found that the optical transmittance and mechanical properties can be effectively controlled and selected through the selection of materials and assembly methods. Besides, the surface properties of MLTW are mainly related to its surface material. In short, MLTW is a new composite material prepared by simple lamination at the macro level. The properties of the material can be controlled through the selection of single-layer materials and assembly methods. Compared with the traditional TW, MLTW has better performance regulation ability.

Photoluminescent Transparent Wood with Excellent UV-Shielding Function

“…The wave numbers of the epoxy resin H758 are 2962 cm –1 (symmetric stretching vibration of C–H group on CH 3 ), 2860 cm –1 (antisymmetric stretching vibration of C–H group on CH 3 ), 1606 and 1506 cm –1 (asymmetric vibration band of benzene ring skeleton), 1456 and 734 cm –1 . The characteristic peaks at CH 3 shear oscillation, 1243 cm –1 (stretching vibration of adipose ether C–O–C) and 827 cm –1 (out-of-plane deformation of para-substituted benzene ring CH) are consistent with previous studies …”

Study on Transparent Basswood Dyed with Reactive Dyes and Its Properties

“…After dyeing treatment of DW, it can be observed that the skeleton vibration of RW increases at 1641 cm −1 , which corresponds to the triazine ring in the dye structure, and the stretching vibration of C−O−C increases at 1160 cm −1 , indicating that the dyed wood contains reactive red X-3B and there may be the formation of dye fiber covalent bonds. 18 Characteristic bands of 2954 cm −1 , 1135 cm −1 (C−H vibration), and 1724 cm −1 (C�O vibration) were found in the infrared spectra of TW and RTW. These bands are related to UV resin, indicating that UV resin successfully impregnated the stained and unstained wood templates.…”

Study of Cutting Power and Power Efficiency during Straight-Tooth Cylindrical Milling Process of Particle Boards

“…Under the environmental protection goal of carbon neutrality and carbon peak, sustainable manufacturing has become the new development direction of the manufacturing industry. This has led to a focus on recycling and the conservation of natural resources and energy in furniture manufacturing processes [1][2][3]. Particle boards (PBs) as a kind of wood-based panel, are widely applied for the manufacturing of custom furniture in China [4][5][6] and milling occupies a large proportion of that manufacturing process [7,8].…”
