Soy-based adhesives have attracted much attention recently because they are environmentally safe, low cost, and readily available. To improve the gluability water resistance of soy-based adhesives, we prepared an enzyme-treated adhesive modified with epoxy resin. We investigated wet shear strength plywood bonded using boiling-water test. Fourier transformed infrared spectroscopy (FTIR) ¹H nuclear magnetic resonance analysis were used to characterize reaction between groups ⁻NH₂ in adhesives....
Wood fibers were prepared as core materials for a vacuum insulation panel (VIP) via dry molding process. The morphology of the wood and microstructure, pore structure, transmittance, thermal conductivity fiber VIP tested. results showed that had excellent properties formed porous structure by interweaving with one another. optimum bulk density led to low-cost highly thermally efficient was 180 kg/m3 200 kg/m3. kg/m3, high porosity 78%, fine size 112.8 μm, total volume 7.0 cm3·g-1. initial...
With rising interior air pollution, health, and food shortage concerns, wood adhesives derived from non-food sustainable materials have therefore attracted considerable attention. Here we developed an eco-friendly cottonseed-lignin adhesive consisting of defatted cottonseed flour (DCF), alkali lignin (AL), graphene oxide (GO). The cation-π interaction, hydrogen covalent bonds between AL@GO DCF collectively enhanced the cross-linking structure cured adhesive, based on Fourier-transform...
To evaluate the effects of preparation conditions a 'green' soy-based adhesive(SBA), Viscozyme L was employed to hydrolyze polysaccharides in defatted soy flour (DSF) for preparing SBAs, and plywood bonded by SBAs with Pinus massoniana veneer then produced. Effects enzymolysis pH, temperature, time, additive amount on water-insoluble substances content (WISC) bonding strength (boiling-water test) were investigated. Results showed that increased first decreased as pH temperature increased....
This paper investigates the perforation treatment of polyvinylchloride (PVC) plastic films and their plywood composites.
The feasibility of heat treatment Masson pine veneers (MPVs) was evaluated based on mass loss, tensile strength, bending and water absorption the heat-treated MPVs, its application in plywood explored.Fourier-transform infrared X-ray diffraction results showed that MPVs contained a lower amount hydrophilic groups had an increased crystallinity.The maximum strength 59.2 MPa when were at 210 °C for 5.0 min.The corresponding (384 h), values 1.72%, 105.44%, 83.1 MPa, respectively.Plywood...
Response surface methodology was employed to determine the effects of enzymatic pretreatment temperature, time, and pH on reducing sugar content bonding strength soy-based adhesives (SBAs).Plywood specimens bonded by SBAs with Pinus massoniana veneer were then produced.A significant positive correlation observed between SBAs.The temperature time also significant, but insignificant respect content; response values smallest.The optimal conditions SBA a 54 °C, 20.0 min, 5.1.Under these...
To improve the mechanical properties of fast-growing Chinese fir (Cunnighamia lanceolate), expand its range application, increase value, and avoid environmental pollution caused by impregnation with synthetic resin, was impregnated a shellac solution. Since solution difficult to penetrate into fir, so microwave pretreatment used irradiate wood permeability. This study investigated effects four factors, including content moisture in before it microwaved, chamber pressure microwave, time...
Fast-growing Chinese fir wood has shortfalls such as loose structure and low strength because it grows faster than natural trees. Resin impregnation is a great way to increase the of fast-growing fir. However, resin used for kind urea-formaldehyde resin, phenolic formaldehyde melamine like, which introduce harmful substances or into wood. In this paper, was impregnated with shellac polymer, effects variables on mechanical properties were examined. The in compression perpendicular grain...
