GB/T 12967.1-2020 Test methods for anodic oxidation coatings and organic polymer coatings of aluminium and aluminium alloys - Part 1: Measurement of abrasion resistance
1 Scope
This part of GB/T 12967 specifies the abrasive blasting method, sand falling method, paper tape wheel abrasion method, rubber wheel abrasion method, rubber abrasion method and friction coefficient measurement method.
The abrasive blasting method is applicable to the measurement of abrasion resistance of anodic oxidation coatings and organic polymer coatings with thickness of coating not less than 5 μm, and is applicable to smaller specimens and those with uneven surface.
The sand falling method is applicable to the measurement of abrasion resistance of anodic oxidation coatings and organic polymer coatings, and is applicable to smaller specimens and those with uneven surface.
The paper tape wheel abrasion method is applicable to the measurement of abrasion resistance of anodic oxidation coatings and organic polymer coatings with thickness not less than 5 μm, and may be used for measuring the overall abrasion resistance of the coatings and the change of abrasion resistance along thickness of coatings, but is not applicable to specimens with uneven surface.
The rubber wheel abrasion method is applicable to the measurement of abrasion resistance of anodic oxidation coatings and organic polymer coatings, and may be used for measuring the overall abrasion resistance of coatings, but is not applicable to specimens with uneven surface.
The rubber abrasion method is applicable to the measurement of abrasion resistance of anodic oxidation coatings and anodic oxidation composite coatings with thickness less than 5 μm, and may be used as reference to functional coatings and texture coatings.
The friction coefficient measurement method is applicable to products such as aluminium floor and aluminium foil which require slip resistance.
