The present disclosure discloses a high-temperature fast-curing starch-based adhesive for particleboards and a preparation method thereof, belonging to the technical field of adhesive preparation. The low viscosity of the starch-based adhesive is ensured by selecting a crosslinking monomer which does not self-crosslink in a reaction process in the present disclosure, and a binary crosslinking agent matched with the crosslinking monomer is added before use to be quickly crosslinked with the crosslinking monomer at high temperature so as to ensure better thermosetting property and water resistance as well as faster curing speed of the starch-based adhesive at the same time, which meets the requirements of the particleboards for the adhesive, solves the problem of long curing time of the existing starch-based adhesives at high temperatures, further shortens the curing time of the starch-based adhesives to about 60 s, and improves the production efficiency of the particleboards.

A bottle forming unit and method for dry-forming a cellulose bottle from an air-formed cellulose blank structure in a bottle forming unit is provided. A first section of the shaped cellulose blank structure is fed to a first forming mould and a semi-closed bottom portion of the cellulose bottle is formed from the first section in the first forming mould, simultaneously with forming the neck portion of a directly preceding cellulose bottle from the first section in the first forming mould. A following second section of the shaped cellulose blank structure is fed to the first forming mould and the neck portion of the cellulose bottle is formed from the second section in the first forming mould, simultaneously with forming a semi-closed bottom portion of a directly following cellulose bottle from the second section in the first forming mould.

A wood substrate or member is included, having an increased density with respect to natural, untreated wood. The process includes drying the wood prior to application of heat and pressure, which are controlled to reduce or eliminate color change on a surface of the wood member where heat and pressure are applied.

A surfacing product (e.g., flooring element) can be elongate along a longitudinal axis. The surfacing product can have a core having a first surface and an opposed second surface that are spaced along a thickness axis. A veneer can be coupled to the first surface of the core. The veneer can have a first veneer segment that is elongate along the longitudinal axis, a second veneer segment that is elongate along the longitudinal axis, and an insert segment positioned between the first veneer segment and the second veneer segment along the longitudinal axis.

A method of producing a veneered element, including providing a substrate, applying a sub-layer on a surface of the substrate, applying a veneer layer on the sub-layer, and applying pressure to the veneer layer and/or the substrate, such that at least a portion of the sub-layer permeates through the veneer layer. Also, such a veneered element.
