Welcome to Huasheng aluminium, the leading manufacturer and wholesaler of hydrophilic aluminium foil. Our innovative product is designed to enhance heat transfer efficiency and humidity control in various applications, making it an ideal choice for air conditioning systems, refrigeration equipment, and more.

What is Hydrophilic Aluminium?

Hydrophilic aluminium is aluminium that has been specially treated or coated to exhibit hydrophilic properties, meaning it has an affinity for water. This unique characteristic allows water or water-based liquids to spread more easily and adhere to the surface. Our hydrophilic aluminium foil is created by subjecting ordinary aluminium foil to a hydrophilic treatment, coating it with anti-corrosion and hydrophilic layers, and then drying it in a drying oven through special processes.

This advanced material is particularly beneficial in applications that require efficient heat transfer or humidity management, such as air conditioner heat exchangers, refrigerators, and other cooling equipment. The hydrophilic coating on the aluminium surface enhances heat exchange efficiency by promoting the uniform distribution of condensate or water across the surface area, thereby improving overall performance.

Hydrophilic Aluminium Foil Properties

The surface of hydrophilic aluminium foil is highly hydrophilic, measured by the angle formed by water adhering to the surface of the foil. The smaller the angle (α), the better the hydrophilic property, with α typically being less than 35°.

Property	Description

Production Process of Hydrophilic Aluminium Foil

Our hydrophilic aluminium foil undergoes a rigorous production process to ensure quality and performance:

aluminium Coil Preparation: High-quality aluminium coils, often of alloys like 8011, are prepared for the coating process.
Surface Treatment: The aluminium coil undergoes a surface treatment process to create a hydrophilic layer. This treatment can involve chemical processes that modify the surface properties of the aluminium.
Coating Application: The hydrophilic coating is applied to the aluminium surface. This coating is designed to enhance wettability, resist corrosion, prevent mildew growth, and offer other desired properties.
Drying and Curing: The coated aluminium is subjected to a drying and curing process to ensure the adhesion and durability of the hydrophilic layer.
Quality Control: The finished hydrophilic aluminium foil undergoes quality control checks to ensure it meets the specified standards and requirements for the intended application.
Rolling and Cutting: The coated aluminium foil is rolled into coils or sheets and cut to the required dimensions for further use in specific applications.

Structure of Hydrophilic Aluminium Foil

Our hydrophilic aluminium foil is a special type of aluminium foil that has been treated to have a hydrophilic (water-absorbent) surface. This treatment is commonly used in air conditioning and refrigeration systems, especially in the construction of heat exchanger fins. The hydrophilic surface helps improve heat transfer efficiency by promoting the condensation of moisture on the fin surface.

Component	Description
Base Material aluminium Foil	The core material is standard aluminium foil. Usually made of high-quality pure aluminium, rolled into thin sheets.
Hydrophilic Coating	Hydrophilic properties are achieved by applying a specialized coating to one or both sides of the aluminium foil.
Surface Treatment	Hydrophilic coatings are usually applied through a chemical or electrochemical process to make them more attractive to water molecules.
Microstructure	Hydrophilic treatment changes the surface of the aluminium foil, reducing its contact angle with water droplets. This means that the water droplets spread and form a film on the surface, rather than beading up.

Storage of Hydrophilic Aluminium Foil

To maintain the quality and performance of hydrophilic aluminium foil, it is essential to store it properly:

Dry Environment: Store hydrophilic aluminium foil in a dry environment with low humidity. Moisture can affect the hydrophilic properties of the foil and cause degradation.
Temperature Control: Keep storage area temperatures stable. Extreme temperatures can affect the structural integrity and performance of foils.
Protect from Contaminants: Keep hydrophilic foil away from dust, dirt, and other contaminants that may affect its surface or hydrophilic coating.

Our aluminum foil products are used in a wide variety of industries and applications, including packaging, automotive, construction, electronics and household. Here are some examples of applications:
