The test materials of poplar were enhanced by dipping PF. Three factors, including dipping concentration, dipping time and vacuum degree, were discussed in the influence of the rate of medicine with the orthogonal test method, and the optimized impregnation process was obtained. At the same time, compression ratio, hot pressing time, hot pressing temperature were discussed in the influence of physical...
Poly (vinyl alcohol) (PVA) is a water-soluble synthetic polymer with excellent adhesive property. But the water resistance is poor. The aim of this study is to explore the suitable formula for PVA cross-linking with sodium silicate to form new kind of wood adhesive which has the perfect bonding strength as well as water resistance. When PVA and sodium silicate are mixed directly, they then become...
