CHANGE of NATURAL DECORATIVE PROPERTIES of WOOD. Emalevidnoe oksidirovanie

Emalevidnoe oksidirovanie is an anodizing version. Difference consists in surface preparation: polishing is replaced matirovaniem. Received anodizatsionnaja the film is exposed to easy polishing. The covering hiding the invoice of metal and reminding enamel as a result turns out.

Ematalirovanie is also an anodizing version. The received film is opaque oksidnym a covering reminding porcelain or plastic of various soft pastel tones. High corrosion firmness, thermal stability, hardness, wear resistance is peculiar to films. They are applied to is decorative-protective furnish of elements of the products which are not exposed to mechanical influences.

At deep, firm anodizing are formed okisnye (anode) films in the thickness from 30 to 300 mk, possessing high hardness, heat resistance (to 1500 В°), wear resistance. Colour of a film more dark, than at ematalirovanii. Reception of firm anode films difficult, labour-intensive process, therefore this method is applied only in separate industries.

Wide application finds in building and mechanical engineering emalirovanie aluminium and its alloys by drawing on a surface melkodispersnyh stekloemalevyh powders in the form of water suspensions (shlikerov) with the subsequent oplavleniem. Coverings possess high hardness, firmness to solutions of acids, washing-up liquids and atmospheric influences, in addition strengthen a design.

Considering high cost galvanic, chemical and anodizatsionnyh coverings, it is necessary to approach to their choice taking into account all complex of technical and economic and operational requirements. The basic requirements to a choice of the coverings put elektroliticheskim, chemical, anodizatsionnym, hot, diffuzionnym, metallizatsionnym and kondensatsionnym in the ways, are regulated GOST 14623-69 “Coverings the metal and nonmetallic inorganic. The basic requirements to a covering choice” and GOST 14007-68 "Service conditions".
