Embodiment 1

[0026] The production process of hydrophilic aluminum foil is:

[0027] (1) The "double-coating and double-baking" production process technology is adopted to produce hydrophilic aluminum foil with good hydrophilicity and strong corrosion resistance.

[0028] Primer coating, also known as corrosion-resistant coating, adopts the coating method of coating on both sides of the strip at the same time, and the rotation direction of the coating roller is opposite to the direction of the strip, that is, reverse coating. The purpose is to evenly coat a layer of anti-corrosion coating on both sides of the aluminum foil, so that the aluminum foil can achieve the purpose of increasing the service life.

[0029] The surface coating is also called hydrophilic coating, and its working principle is the same as that of the primer. The purpose is to apply a layer of hydrophilic coating evenly on both sides of the primer, so that the water droplets on the fins will spread rapidly, and the water...

Abstract

The invention relates to the components of the general heat exchange or heat transfer equipment in the heat exchange field, more particularly, relates to the making method of the hydrophilic aluminum foil. The invention mainly solves technique problems of bad hydrophilic property and low corrosion resistance of the prior art; the invention provides the making method of environment-friendly high performance hydrophilic aluminum foil with reasonable design, excellent hydrophilic property and rather strong corrosion resistance. The invention has the major technique proposal that: the curing method of the coating layer develops into an advancer and evener air cushion suspension type hot blast circulation heating means from the original infrared heating means by adopting the two-coating and two-baking technique.

Description

technical field [0001] The invention relates to parts of general heat exchange or heat transfer equipment in the field of general heat exchange, in particular to a method for manufacturing hydrophilic aluminum foil. Background technique [0002] Hydrophilic aluminum foil is a composite material based on aluminum foil. It has good heat dissipation of ordinary aluminum foil, and has corrosion resistance and hydrophilicity that ordinary aluminum foil does not have. It is a substitute for ordinary aluminum foil for air-conditioning heat exchangers. [0003] The surface of hydrophilic aluminum foil has strong hydrophilicity. When used in air conditioners, it can make the water droplets in the hot air condense on the heat exchange sheet easy to spread and flow down the sheet. The water droplets between the heat sheets "bridge" to affect the ventilation effect of the heat exchanger, thereby increasing the heat exchange rate by 5%. In addition, hydrophilic aluminum foil also has ot...
