Metal wood laminate

Boron has been included as a neutron absorber in various materials in addition to concrete. For example, borated graphite, a mixture of elemental boron and graphite, has been used in fast-reactor shields. Boral, consisting of boron carbide (B4C) and aluminum, and epoxy resins and resin-impregnated wood laminates incorporating boron have been used for local shielding purposes. Boron has also been added to steel for shield structures to reduce secondary gamma-ray production. In special situations, where a shield has consisted of a heavy metal and water, it has been beneficial to add a soluble boron compound to the water.

Epoxy resins are widely used as adhesives, surface coatings, encapsulates and casting materials. They are used in industrial tooling applications to produce moulds, master models, laminates, castings, fixtures, and other industrial production aids. This plastic tooling replaces metal, wood and other traditional materials, and generally improves the efficiency and lowers the overall cost or shortens the lead-time for many industrial processes. Epoxy resins are extensively used as a binder for marine paints, which is required to protect the naval structure from the corrosive marine environment. 

Occupations involved with manufacturing furniture, cabinets and fixtures can involve handling materials made of wood, laminates, metal, synthetics, plastics resins, reeds, rattan, upholstery fabric, leather, adhesives, and finishing products. For simplicity, the general categories of fabrication, assembly, repair, finishing, and upholstery are discussed. Table i gives examples of some of the job titles used in furniture manufacture.

Decorative panels are made by laminating vinyl or wood veneer to structural panels which can be steel, aluminum, pl)nvood, or particle board. Foam cores between the structural panels offer stiffness, sound deadening, and thermal insulation. Metal-polymer laminates are used as decorative panels in buildings. A viscoelastic core can be added between the metal sheets for sound damping. 

Water-borne adhesives are preferred because of restrictions on the use of solvents. Low viscosity prepolymers are emulsified in water, followed by chain extension with water-soluble glycols or diamines. As cross-linker PMDI can be used, which has a shelf life of 5 to 6 h in water. Water-borne polyurethane coatings are used for vacuum forming of PVC sheeting to ABS shells in automotive interior door panels, for the lamination of ABS/PVC film to treated polypropylene foam for use in automotive instmment panels, as metal primers for steering wheels, in flexible packaging lamination, as shoe sole adhesive, and as tie coats for polyurethane-coated fabrics. PMDI is also used as a binder for reconstituted wood products and as a foundry core binder. 

High-pressure laminates. Solvent-borne CR adhesives are used for bonding foams to wood or fabric, and for bonding metal, fibreglass and plastics. 

Laminating is the process of adhesive bonding of layers of metal, plastic, or wood to form apart. 

Paper coatings and finishes (paper laminates for wood decoration, high-gloss paper for gift wrapping, lacquer on metallized paper)... 

Other copolymers of this type with vinyl acetate or vinyl butyral resins have been found satisfactory for use in the lamination of wood, glass and metals. Glass-resin adhesives are also known. 

Decorative laminate is defined in ISO 472 but in common usage has come to mean sheet materials consisting of decorative surface papers impregnated with melamine resin and consolidated under heat and pressure with plies of core paper permeated with phenolic resin. In a wider sense the term can be applied to many associated products—including laminates in solid colour laminates with facings such as metal foils, textiles, or wood veneers polyester laminates direct faced boards and composite boards comprising thin laminates bonded to substrates of various kinds.
