Before assembling the test device, it should be placed in the laboratory environment for a sufficient time to make its temperature consistent with the ambient temperature. 6.2 Assembly of the test device. Punch a 15mm diameter through hole in the center of the surface of a No. 13 rubber stopper and two No. 9 rubber stoppers. Press the test piece processed in 4.2.4 into the through hole of the large surface of the No. 9 rubber plug, so that the test surface is parallel to the large surface of the No. 9 rubber plug, and the part of the test piece protruding from the large surface of the No. 9 rubber plug does not exceed 3mm, as shown in Figure 1. Pass the aluminum tube through the center of the No. 13 rubber plug, and insert the No. 9 rubber plugs into the exposed aluminum tubes at both ends, respectively, with the small surfaces of the two No. 9 rubber plugs facing the No. 13 rubber plug. Pre-sleeve an insulating rubber tube between the small surface of the No. 13 rubber plug and the No. 9 rubber plug with the test piece. The saw tube in the No. 9 rubber plug with the test piece should be in contact with the concave surface of the test piece.

A pin was pinned to the lower end of the sample to make it droop naturally. The assembled rubber plug was placed in a 1000mL wide-mouth bottle. The bottom of the bottle was pre-filled with 10mL of 95% glycerol distilled water, so that the wide-mouth bottle formed a relative humidity of 90% at 20℃, as shown in Figure 2. The assembled wide-mouth bottle was placed in an incubator at 20℃±1℃, and taken out after 20h. The aluminum tube on the wide bottle was quickly filled with water at a temperature of 0℃~2℃, and then immediately placed in an incubator at 20℃±1℃. After 3h, the test body was taken out, the water in the aluminum tube was poured out, and the rust on the test surface was immediately checked. If there is visible condensation on the test surface, immediately use tweezers to pick up a cotton wool soaked in anhydrous ethanol, gently wipe it and then check it. Four groups of parallel tests are performed, one of which is a blank test. 7.1.2 Test of gas phase rust inhibitor Inject 10mL of 35% by mass propylene glycol distilled water solution into the bottom of the wide-mouth bottle to form 90% 3 GB/1 16267--2008 in the wide-mouth bottle at 20℃. 0.5% powdered gas phase rust inhibitor is evenly distributed in the glassware, and then the bottom of the bottle is placed. The test device is assembled according to the method in 6, 2 and put into the wide-mouth bottle, as shown in Figure 3. The assembled product bottle is placed in an incubator at 20℃±1℃, and water at 0℃~2℃ is added to the top of the bottle, and then it is immediately returned to the incubator at 20℃±1℃. If the test object is not of good quality, drain the water from the inclined tube and check the rust of the test equipment. If there is visible dew on the surface of the milk test surface, remove it immediately with cotton wool without anhydrous ethanol and wash it gently before checking. The test group of the positive red north is the research group.

The gas phase anti-rust plastic film with gas phase anti-rust agent is sealed into a 100mm×400mm sealed film after air is completely removed from the film. The film is placed in a drying oven at C=2℃ for 12h, 72h, 48h, 24h, and cooled naturally to room temperature. Then, the sample test is carried out according to the provisions of 7.1.1. 7.2.2 Gas phase anti-rust filter test 0.5g powdered gas phase anti-rust agent is added to the filter paper with a size of 12um. Place in a medium box at 60℃ to 2℃ for 120h, then take out and cool naturally in the air.
