GB/T 8005.3-2008Aluminium of aluminium alloys -- Terms and definitions -- Part 3: Surface treatment (English PDF)

Foreword

GB/T 8005 "aluminum and aluminum alloy term" is divided into three parts.

--- Part 1. Product and processing technology;

--- Part 2. Chemical analysis;

--- Part 3. Surface treatment.

This section GB/T 8005 Part 3.

The partial modification of the use of ISO 7583. 1986 "aluminum and anodized aluminum term," and according to ISO 7583. 1986 re-drafted.

For ease of comparison, the data are listed in Appendix A of this part of the list of control clauses and the corresponding chapter of the international standards.

This section in the use of international standards has been modified. The technical differences between the single vertical line in terms of their identity involved margins Margin. The main technical differences are as follows.

--- In the "Range" set forth the terms and definitions in this section apply to the surface treatment of aluminum and aluminum alloys;

--- Increased Chapter 6, "Painting and paint" content, including 26 entries;

--- Increases the performance of detection and the content of the organic polymer film, comprising 47 entries;

--- Added "natural oxidation 2.2", "2.20 washing", "organic polymer coating film 2.26", "2.27 Functional oxide Film "," plating 2.28 "," 2.29 plating "," color 2.30 ", 3.1" surface preparation "," satin handle 3.2 " 3.3 "matt", "3.14 emulsion degreasing", "organic solvent degreasing 3.15", "3.17 ultrasonic cleaning" "Recovery 3.29", 4.3 "pulse anodizing," "constant current anodizing 4.12", "5.6 multicolor coloration" "Hydration heat sealing 5.11", "5.13 boiling water sealing", "cold sealing 5.16", "5.20 Medium temperature sealing" 21 entries;

--- Remove the impedance test, the loss factor, burning, chalking, peeling, stress cracking, frost weathering spots, plugging gray, orange peel and other 18 items.

This Part replaces GB/T 11109-1989 "anodized aluminum and aluminum term." this section compared with the GB/T 11109-1989, the main changes are as follows.

--- Standard name to read. "The term aluminum and aluminum alloys - Part 3. Surface treatment term";

--- Extend from aluminum and anodized aluminum alloys to the surface treatment;

--- Adjust the chapter structure. This section divided into six chapters. 1. Basic vocabulary; 2. Surface pretreatment; 3. Anodizing; 4. Coloring and sealing;

5. Painting and paint; 6. Performance and testing. Each class in terms rearranged in accordance with the technical concept or process sequence;

--- An increase of 94 entries, 13 entries deleted.

1 Scope

This section provides the basic vocabulary of aluminum and aluminum alloy surface treatment, surface preparation, anodizing, coloring and sealing, paint and coatings, Performance and testing of six terms and definitions.

This section applies to surface treatment of aluminum and its alloys.

2 Term basis

An electrochemical oxidation process. The surface of aluminum or aluminum alloy in the process is typically converted to the oxide film, the protective film has, mounted or other decorative features.

No artificial oxidation process accelerated in the atmosphere.

Chemical generation processing aluminum oxide film in an oxidizing chemical solution, formerly known chemical oxidation.

During electrolysis, negative ion discharge electrode to generate positive ions or other oxidation reactions.

During electrolysis, the positive ion discharge electrode to generate negative ions or other reduction reactions.

In the electrolysis process, to a uniform distribution of the cathode current or additional anode oxide film to obtain a uniform employed.

Unit surface area of \u200b\u200bthe electrode by the current intensity. Usually amperes per square meter (A/m2) or amperes per square decimeter (A/dm2) FIG.

Specific current density electrolysis occurs is different sometimes unexpected reaction electrode above or below this value.

The ratio of the oxide film effectively consumed current according to Faraday's law electric current between the calculated theoretical formed during the anodic oxidation, through Commonly expressed as a percentage.
