Introduction

Aluminum and aluminum alloy anodic oxide film and organic polymer film are used for the protection and decoration of aluminum and aluminum alloy surface.

It is widely used in many fields such as appliances, home appliances, interior decoration, food packaging, mechanical parts and functional materials. GB/T 8013 "Aluminum and aluminum alloy anodes Oxide Films and Organic Polymer Films stipulate the general technical requirements for all types of aluminum surface anodization and organic polymer films, aiming to meet The needs of different users. GB/T 8013 establishes general technical requirements for general-purpose films, and also establishes a decorative effect with texture And/or the technical requirements of the specific function of the film.

GB/T 8013 is planned to consist of five parts.

---Part 1: Anodized film. The purpose is to establish general-purpose anodic oxide film performance evaluation methods and requirements.

---Part 2: Anodized composite film. The purpose is to establish a general-purpose anodic oxide composite film performance evaluation method And requirements.

---Part 3: Organic polymer coating film. The purpose is to establish a general-purpose organic polymer coating film performance evaluation method And requirements.

---Part 4: Textured film. The purpose is to establish the evaluation method and requirements of the film layer performance with texture decoration requirements.

---Part 5: Functional film. The purpose is to establish specific performance evaluation methods and requirements for films with specific functional requirements.

In 1987, my country first formulated GB/T 8013-1987 "Aluminum and Aluminum Composites" in accordance with ISO 7999:1983 "General Specification for Aluminum General Specification for Gold Anodized Anodized Film. In.2007, referring to the new changes and new needs of relevant domestic and foreign standards, my country

GB/T 8013-1987 has been revised, based on GB/T 8013.1-2007 "Aluminum and aluminum alloy anodic oxide film and organic polymer film No. 1 Part. Anodic Oxide Film" instead of GB/T 8013-1987, and GB/T 8013.2-2007 "Aluminum and Aluminum Alloy Anodic Oxide Film and Organic Polymer Film Part 2: Anodic Oxidation Composite Film, GB/T 8013.3-2007 Aluminium and Aluminum Alloy Anodic Oxide Film and Organic Polymerization Physical Film Part 3: Organic Polymer Spray Film" to meet the application requirements of electrophoretic coating, electrostatic spraying, roller coating and other surface treatment films. close Over the years, the anodized texture film or organic polymer texture film (texture film for short) made by various texture processing methods, and through special Anodized functional film or organic polymer functional film with specific functions such as antibacterial, non-stick and high wear resistance obtained by special surface treatment (simplified (Called functional film), the application on aluminum alloy products is more and more extensive, and the development prospect is broad, but GB/T 8013.1~GB/T 8013.3 Many of the film performance evaluation methods and requirements specified in the

GB/T 8013.4 and GB/T 8013.5 were supplemented in China.

GB/T 8013.4 focuses on supplementing the specific evaluation methods and requirements of textured films, and standardizing the inspection methods and performance requirements of textured films to meet the requirements of The user pursues the aesthetic needs of materials with multi-color patterns or multi-style three-dimensional effects.
