Embodiment 1

[0020] 1. Sample preparation:

[0021] Select two identical metal parts, one of which is used as the sample to be tested and the other as the control sample, and record the flaws, marks and appearance of the sample to be tested in detail.

[0022] 2. Pretreatment environment: temperature is 21±2℃, relative humidity is 65%±2%

[0023] The test samples were placed in this preconditioning environment and allowed to stand for at least 4 hours.

[0024] 3. Test steps:

[0025] 1. Prepare a NaCl solution with a concentration of 1%, completely soak the pure cotton white cloth with the NaCl solution, and soak for 1min;

[0026] 2. After soaking, take out the pure cotton white cloth, gently squeeze out the excess solution on the pure cotton white cloth, so that there is no solution dripping;

[0027] 3. Wrap the sample to be tested with a soaked pure cotton white cloth, so that the contact surface between the sample to be tested and the pure cotton white cloth should be as large as ...

Abstract

The invention relates to a method for testing rust-proof and corrosion-resistant properties of metal parts used on garment products. The method comprises the following steps: selecting the two identical metallic components, and using one as a sample to be tested, and the other as a control sample; placing the sample to be tested in the pretreatment environment at the temperature of 21 DEG C+ / -2 DEG C and with the relative humidity of 65% plus or minus 2%, and allowing the sample to stand for at least 4 hours; preparing a NaCl solution with the concentration of 1%, taking a piece of pure cotton white cloth; completely soaking the white cloth in the NaCl solution; after the completion of the soak, taking out the pure cotton white cloth; lightly extruding out excess solution on the pure cotton white cloth; using the soaked the pure cotton white cloth to wrap well the sample to be tested, and placing the sample in an oven at the temperature of 38 DEG C+ / -1 DEG C; and after taking out the sample, comparing the sample to be tested and the control sample and recording and assessing the differences of the sample to be tested, wherein the greater the difference, the rust-proof and corrosion-resistant properties are worse. The method has the benefits that the rust-proof and corrosion-resistant properties of the metal parts used on the garment products can be tested and accessed; the method is simple and convenient; and test results are intuitive and clear.

Description

[technical field] [0001] The invention relates to the technical field of anti-rust and anti-corrosion testing, in particular to a method for anti-rust and anti-corrosion testing of metal parts used in clothing products. [Background technique] [0002] As accessories of clothing products, metal accessories are mainly used in metal zippers, metal snap buttons and other metal fastening parts. Because of their good durability, metal accessories are widely used in adults, children, and babies. And other clothing products. However, based on the inherent characteristics of the metal accessories, the metal accessories may be corroded or rusted on the metal accessories due to the influence of the external environment during use, and the corrosion and rust produced Can cause stains on clothing products and are difficult to remove. Therefore, there is an urgent need for a test method to test and evaluate the anti-rust and anti-corrosion properties of metal parts used in clothing prod...
