CHANGE of NATURAL DECORATIVE PROPERTIES of WOOD. Metallization

Metallization . Metallization as a kind of is decorative-art furnish of elements of furniture was most widely used in furnish of palace furniture and the equipment of interiors of the period of late revival (baroque, rococo). Specially prepared surface of wood completely disappeared under a thin layer of metal - bronze, silver, gold. The technics of gilding, silvering and bronzing has been brought to perfection. Now these kinds of furnish have lost the is decorative-art value and are applied basically at restoration works.

Recently in connection with development of technics and technology metallization starts to draw again attention of designers as one of perspective kinds of is decorative-protective furnish of nonmetallic materials.

Metallization of nonmetallic materials is made in practice plakirovaniem, impregnation by metal under pressure, dispersion of the fused metal and drawing poroshkoobraznogo metal in vacuum.

Plakirovanie (folgirovanie) sheet materials on the basis of wood is made by gluing on a plywood surface drevesnostruzhechnyh or wood-fiber plates thin (0,025 mm) a layer of metal (foil) from aluminium, copper or a brass. As glutinous materials are used bakelitovaja a film of mark And (GOST 2707-75), glues БФ-2, 88-N, etc. Thus at enough high durability of pasting design consolidation as a whole is observed. Decorative qualities of coverings are defined by a condition of a surface of a foil, its invoice and a protective transparent covering.

Impregnation of wood by metal under pressure is made in autoclaves and consists in forcing in wood fused fusible (svintsovo-olovjanistogo) an alloy at the pressure considerably exceeding the atmospheric.
