Problems solved by technology

[0009] The technical problem to be solved by the present invention is that the prior art can only evaluate the antirust property or dehydration property of the dewatered antirust oil alone, and cannot quickly test the actual effect of the dehydrated antirust oil when used in a water-containing environment, and cannot simultaneously describe The problems of dehydration, rust prevention and oil film condition of dehydration antirust oil provide a new test method for the performance of dehydration antirust oil

Embodiment 1～2

[0028] Wrap the metal adsorption material in the filter membrane to obtain metal purses, see Table 1 for details of each metal purse.

[0029] [Example 1] The metal purse was fully soaked and adsorbed in water for 60 seconds, and then drained for 30 seconds. Inject different types and brands of dehydrated antirust oils A, B, C, D, E and F on the market into the dehydration tank with a metering tube. Dip the drained metal purse into 450 grams of dehydrated antirust oil to be tested, and suspend it in the dehydration tank. Start timing from the moment when the metal purse is completely immersed in the dewatered antirust oil to be tested, and record the time when the first drop of water falls and the water volume reading in the metering tube, so as to evaluate the dehydration of the dehydrated antirust oil to be tested. The test results are shown in Table 2.

Embodiment 3

[0036] The metal purse of [Example 2] was fully soaked and adsorbed in water for 90 seconds, and then drained for 20 seconds. Inject the oil to be tested into the dehydration tank with metering tube. Dip the drained metal purse into 600 grams of the oil to be tested and hang it in the dehydration tank. Start timing from the moment the metal purse is fully immersed in the oil to be tested, record the time when the first drop of water falls and the water volume reading in the metering tube. The dehydration performance of different types and brands of dehydrating antirust oils A, B, C, D, E, F and G and one non-dehydrating antirust oil in the market was tested. Take the metal purse out of the oil to be tested, and evaluate the dehydration antirust oil A, B, C, D, E, F and G and a non-dehydration antirust oil according to the rust imprint on the purse filter membrane and measure the area of ​​the rust Oil rust resistance.

[0037] Put the metal purse on the filter paper, and ev...

Abstract

The invention relates to a method for testing the use performance of dewatering rust preventive oil, and mainly solves the problems existing in the prior art that the rust preventive performance or the dewatering performance only can be independently evaluated, the actual effect achieved by the dewatering rust preventive oil during the use in a water-containing environment cannot be rapidly tested, and the dewatering performance, the rust preventive performance and the oil membrane state of the dewatering rust preventive oil cannot be described at the same time. The method wells solves the problems through adopting the steps as follows: a) metal adsorbing material is wrapped in at least one filter membrane to obtain a metal pouch, and the dewatering performance of the dewatering rust preventive oil to be tested is evaluated through testing the actual dewatering time and the dewatering amount of the metal pouch already absorbing water; b) the rust preventive performance of the dewatering rust preventive oil is evaluated according to the situation of corroded blots on the filter membrane of the pouch and the measurement of the areas of the corroded blots; and c) the oil membrane condition of the dewatering rust preventive oil is evaluated according to the diffusion diameter of a residual oil membrane on the metal pouch on the filter paper. The method can be used in formulation research and product quality inspection of the dewatering rust preventive oil.

Description

technical field [0001] The invention relates to a method for testing the service performance of dehydrated antirust oil. Background technique [0002] The main performance of dehydration anti-rust oil includes dehydration, anti-rust and oil film state. [0003] At present, the test methods commonly used at home and abroad to evaluate the dehydration performance of dehydrating agents or dehydrating anti-rust oils include the dehydration test method based on whether the test piece is rusted or not, and the dehydration test method based on the diameter of the water film of the replacement test piece. Test method, dehydration time measurement method. The dehydration test method based on whether the test piece is rusted or not is simple to test, but there are two shortcomings in this type of method. One of the disadvantages is that the test period is long, and it usually takes more than 3 hours to complete the test, so it cannot meet the needs of product research and developmen...
