Preparation of Environmentally Friendly Glueless Boxwood Timber by Acidic Environmental Treatment and High-Temperature Pressing

Abstract

In the context of high-quality development, environmental issues are being paid more and more attention to, and the release of free formaldehyde has become a major problem that needs to be solved. Glueless plywood mainly adopts natural substances as raw materials, without adding chemical products, such as resin adhesives, and it does not contain harmful substances, such as formaldehyde. Glueless plywood is a green product that causes no pollution in the environment and no harm to the human body. In this study, the corresponding weak-phase components in boxwood were pre-delivered by an acidic environmental treatment, and the high-temperature and high-pressure compacting process produced a glueless boxwood panel with excellent water resistance and mechanical properties, while remaining environmentally friendly.

Study on the Difference of Superhydrophobic Characteristics of Different Wood Furniture Substrates

“…Based on the Cassie and Baxter model, as well as extensive research, the contact between a water droplet on a superhydrophobic surface and a solid surface comprises two forms of contact, namely, solid–liquid contact and liquid–gas contact. In an acidic environment, there is some direct interaction between an acidic solution and modified wood, which results in the breaking of hydrogen bonds between molecules [ 37 ]. Additionally, acid or alkali solutions can corrode and dissolve some of the silicon dioxide in the coating, as well as the low surface energy silane on the surface, which may spall off, causing the original rough structure to deteriorate and a reduction in surface hydrophobicity.…”
