Background technology
Hydrophobicity also claims hydrophobicity, is that material is a kind of when contacting with water in air can not be by the character of water-wet.Reason is when interactional cohesive force is less than the cohesive force between the hydrone between material molecule and the hydrone, hydrone can not be spread at material surface and scatter, can only roll at the material surface glomeration, roll on lotus leaf, so be commonly called as lotus leaf effect just as the globule.At this moment, in the junction of material, water and air, the interior angle that becomes with material surface along the tangent line on water droplet surface, i.e. contact angle θ＞90 °, material presents hydrophobicity; In contrast, the interactional cohesive force between material molecule and the hydrone is during greater than the cohesive force between the hydrone, and hydrone will inevitably be spread at material surface and scatter.At this moment, in the junction of material, water and air, the interior angle that becomes with material surface along the tangent line on water droplet surface, i.e. contact angle θ≤90 °, material presents hydrophily.
The common aluminium that does not have hydrophobicity, or the hydrophily aluminium is when using in refrigerating environment, when surface temperature is lower than the dew point of surrounding air, hydrogenesis in the surrounding air becomes water droplet, not only reduced the heat exchange effect of refrigeration system, thereby increased energy consumption, increased the corrosion chance of aluminium material surface simultaneously, reduction of service life.Especially when air-conditioning when outdoor air subzero environment heats work, the heat-exchanging part of outdoor body is being born sending into after the outdoor heat conversion indoor, the water droplet that the heat-exchanging part surface condensation becomes must be frozen into frost and be attached to the surface in outdoor air subzero environment, cause heat exchange effect sharply to reduce on the one hand, on the other hand in order to guarantee the operation that works on, the air-conditioning heating operation of having to temporarily stop, reinstate the defrosting program, refrigerating operaton in reverse direction, in order in the heat-exchanging part of outdoor body, produce heat to remove the frost that outdoor body heat replacement part surface condensation becomes, this has just caused the waste of the defrosting energy, and heating effect was low when air-conditioning carried out heating operation at outdoor air subzero environment.
