In at least one specific embodiment, a method for making an emulsified hydrophobizing composition, can include mixing a hydrophobizing agent, a liquid medium, and a lignosulfonic acid or salt thereof to provide a hydrophobizing composition and emulsifying the hydrophobizing composition using hydrodynamic cavitation to provide an emulsified hydrophobizing composition. The emulsified hydrophobizing composition can have an average particle size of about 0.3 microns to about 160 microns. The method can also include maintaining the emulsified hydrophobizing composition at a temperature of greater than a melting point of the hydrophobizing agent for at least 10 minutes.

This invention discloses adhesive compositions useful for providing cohesive strength to particles, for example a mat of wood particles produced while making particleboard prior to curing. The adhesive compositions has a) one or more biopolymers and b) one or more monomers or oligomers. An oligomer may have a degree of polymerization of 4 or less. The weight ratio of the monomer/oligomer to the biopolymer is optionally between 30:70 and 80:20. Optionally, the adhesive compositions may be combined with an isocyanate. The adhesive composition may be used to make no added formaldehyde wood composites such as particleboard.

The MDI included Net Zero Green Energy Pallet Composition, wherein the MDI included Net Zero Green Energy Pallet is composed of recycled wood, processing residual wood, sawdust, straw, etc., which are processed by machines, crushed and dried, and the wood chips are mixed with methylene diphenyl diisocyanate (MDI) component glue, made by hot-pressing molded. Among them, the MDI included Net Zero Green Energy Pallet has a primarily 22 grid look, consisting of a pallet body, numerous support legs, and multiple reinforcing ribs, combined with conveyor belt components or double-sided pallet type. When there are nine support legs, the outside of the legs are trapezoidal and the inside is concave downward, which includes the left, center, and right support legs. The reinforcing ribs are hot-pressed and molded into grooves on the pallet's surface, and they include connecting and arc-shaped reinforcing ribs, as well as central connecting and reinforcing ribs.

In some examples, one or more metal-containing catalysts and one or more waxes can be mixed or otherwise combined to produce an encapsulated catalyst composition. The wax can be at least partially coated on the metal-containing catalyst. A mixture of water and the wax can be agitated or otherwise mixed, and the metal-containing catalyst can be added to or otherwise combined with the water and wax mixture to produce a wax emulsified catalyst. A plurality of lignocellulose substrates, one or more oxidants, and the encapsulated catalyst composition can be mixed or otherwise combined to produce a lignocellulose binder mixture. The lignocellulose binder mixture can be heated to produce a composite product.

A method of manufacture of medium and high density fibreboard with moisture and mildew resistance and low formaldehyde emission, which includes the steps of: (a) providing wood chips; (b) pre-steaming; (c) refining the wood chips into fibers and adding 200-230 kg/m.sup.3 urea-formaldehyde resin adhesive, nigrosine solution with a mass percentage of nigrosine in absolutely dried fiber of 1-1.2%, 6-8 kg/m.sup.3 refined paraffin and 1.5-2 kg/m.sup.3 curing agent; (d) feeding activated carbon of 100-200 mesh to mix with the fibers and then drying the fibers to a water content between 8-10%; (e) separating qualified fibers to measuring silo; (f) laying the fibers onto a mat formation platform uniformly to form a fiber mat by pre-pressing; (g) pre-heating the fiber mat; and (h) processing continuous hot-pressing to form a raw board. The resulting fiberboard is black in color, has good physical properties and low formaldehyde emission rate.

The instant disclosure relates to an engineered wood precursor mixture. The engineered wood precursor mixture includes wood components and a binder reaction mixture. The binder reaction mixture is present in a range of from 3 parts to 25 parts per 100 parts of the dry weight of the plurality of wood components.
