This standard is drafted by the National Nonferrous Metals Standardization Technical Committee, the National Nonferrous Metals Standardization Technical Committee is responsible for the drafting of this standard: Tianbei Pan Industry Co., Ltd. The main starters of this standard are Mingxiang, Kongyang Peng, Gongshu, Cheng Jie, Xie Xin, Zhang Yang, Shang Anzhi, this standard The technical requirements of the National Nonferrous Metals Standardization Committee are explained in detail. 1. Test method for aluminum foil Part 1 Test method for the wetting tension of aluminum foil surface This part defines the wetting tension test method. This method is applicable to the surface of aluminum foil products. 2. Principle of the method YS/T455.1—2003 This method is based on the test method of repeated verification of the surface properties of materials. Different test liquids are selected to test the wetting tension of the foil. 3. Test liquid and materials 3.1 Neutral (analytical grade) 3.2 7.2 Nitrate (analytical grade) 3.3 Degreasing sieve 3.4 Test bottle 4 Preparation of test liquid
According to the volume number in the table, transfer formyl and acetyl alcohol to prepare the test solution, put them into the test bottle and prepare: Table 1
Surface humidity (mm × 13N/m2)
5 Test piece
Energy/ml
5.1 Test under normal temperature, humidity: 232C, relative humidity: 50°C) 5.2 The tested agent should be at least 3mm above the surface. 6 Test method
Energy/mL
Use a ball to take the prepared test solution and test on an area of ​​not less than 603mm on the surface of the standard: If the test solution does not break into small pieces, the test method can be repeated in the next step until the test solution is formed on the surface of the test piece. The corresponding test in the previous step is shown in Table 1
yS/T 455.12003
The surface wetting tension is defined as the wetting value of the inspected box. If the test liquid used for screening cracks within 2, re-sample and brush with the test liquid with low wetting tension until the test screen remains unchanged within 2! The surface wetting tension of this test is defined as the wetting tension value of the inspected box.
