Description

Technical Field

[0001] The utility model patent belongs to the technical field of hydrophilic aluminum foil performance testing, and specifically relates to a hydrophilic aluminum foil continuous immersion hydrophilic angle pre-treatment testing device. Background Art

[0002] Hydrophilic aluminum foil is usually used to make air conditioner radiator fins. It has strong hydrophilicity, which is conducive to the rapid diffusion of condensed water on the surface of the fins, thereby effectively eliminating the water bridge effect between the fins and ensuring good ventilation effect of the air conditioner.

[0003] The quality of hydrophilic aluminum foil is usually evaluated by measuring the contact angle formed by water droplets on its surface. The contact angle reflects the degree of hydrophilicity. Hydrophilicity can be divided into initial hydrophilicity, continuous hydrophilicity, and dry-wet infiltration hydrophilicity. Among them, continuous hydrophilicity mainly simulates the actual use environment of hydrophilic aluminum foil and tests its hydrophilicity through long-term running water flushing. The test requires that the hydrophilic aluminum foil be immersed in a container with a flow rate of 1L / min to 3L / min for 100 hours, then dried and the contact angle measured. Three samples are taken from each group and the average value is taken.

[0004] However, the existing technology has some shortcomings: first, the samples are placed overlappingly, which makes it difficult for the hydrophilic aluminum foil in the middle to fully contact the running water for flushing; second, the use of tap water will lead to differences in water quality, making it difficult to ensure the consistency of the test results, and continuous running water will cause waste of resources; finally, each group of samples is in a different flushing position, making the test conditions inconsistent and making it difficult to ensure the stability and repeatability of the results.
