1 Scope

This part of GB/T 22638 specifies the method for the determination of the surface density of aluminum foil coatings. This part applies to the determination of the surface density of the coated aluminum foil coating. The high temperature baking method specified in this section applies to the determination of the surface density of the coating.

2 normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. Representation and Judgment of Numerical Correction Rule and Limit Value of GB/T 8170

3 Principle of the method

Place the known area and mass of the sample in the concentrated concentration of concentrated sulfuric acid (for organic coating), or into the muffle furnace at high temperature (For organic coating, inorganic coating, mixed coating). After the coating is completely removed, the sample mass is weighed and the unit area of the sample is calculated Mass loss, that is, coating surface density.

4 reagent

Concentrated sulfuric acid (ρ = 1.84 g/mL).

5 instruments and equipment

5.1 Analysis of the balance, the sense of 0.1mg. 5.2 muffle furnace, the temperature can be controlled at 550 ℃ ± 5 ℃. 5.3 oven, the temperature can be controlled at 100 ℃ ± 1 ℃. 5.4 beaker, 1000mL. 5.5 sampler, quantitative sample area of 0.01m2 quantitative standard sample sampler.

6 samples

Use a sampler (5.5) to draw a circular sample with an area of 0.01m2. The area deviation of the specimen should not be greater than ± 0.35cm2.

7 concentrated sulfuric acid method

7.1 Place the sample in an oven (5.3) at 100 ° C ± 1 ° C for 5 min and remove it with tweezers. Place in a dry dish and allow to cool. ......
