Colour-coated hydrophilic aluminium panels: a dual upgrade in functionality and decoration Colour-coated hydrophilic aluminium panels are functional panels developed based on traditional colour-coated aluminium panels, featuring **hydrophilic properties** achieved through special surface treatment. They retain the colour diversity and decorative appeal of colour-coated aluminium panels while offering core advantages such as efficient water repellency, anti-condensation, and ease of cleaning. These panels are widely used in evaporators and condensers of refrigeration equipment such as air conditioners, refrigerators, and air-source heat pumps, as well as in building decoration applications in humid environments. The following analysis covers technical principles, core characteristics, and application scenarios: 1. Core Technology of Colour-Coated Hydrophilic Aluminium Panels: From Coating to Hydrophilic FunctionalityThe ‘hydrophilic properties’ of colour-coated hydrophilic aluminium panels are not naturally inherent but are achieved through a base material pre-treatment + functional coating composite  process. The core technical pathways include: 1.Base Material Selection: Aluminium Substrates Suitable for Functional Requirements- Typically, 1-series (pure aluminium) or 3-series (aluminium-manganese alloy) aluminium sheets with a thickness of 0.1–0.3 mm (commonly used for air conditioning heat exchanger fins) are selected, which offer excellent ductility and thermal conductivity: - 1-series pure aluminium: Purity ≥99.5%, high thermal conductivity (237 W/(m·K)), suitable for high heat exchange efficiency requirements; - 3-series aluminium-manganese alloy: Manganese is added to enhance strength, offering superior corrosion resistance compared to pure aluminium, making it suitable for humid environments. - The substrate surface must undergo **degreasing, phosphating, or chromate treatment** to remove oil residues and oxide layers, enhance coating adhesion, and prevent peeling in later stages. 2. Hydrophilic coating technology: the carrier of core functionsHydrophilic coatings are the ‘soul’ of colour-coated hydrophilic aluminium sheets. They achieve optimised surface ‘wettability’ by adding hydrophilic groups (such as hydroxyl or carboxyl groups) or nano-scale hydrophilic materials** to the colour-coated primer or topcoat. Mainstream coating types include: (1) Organic hydrophilic coating (mainstream application) - Composition: Based on polyester or acrylic resin, with hydrophilic additives (such as polyethylene glycol, surfactants) and nano-silica (to enhance wear resistance); - Process: Applied via roller coating or spraying onto the surface of colour-coated aluminium sheets, with a thickness of 3–5 μm (thinner than traditional colour coatings to avoid affecting thermal conductivity); - Hydrophilic principle: Hydrophilic groups in the coating form hydrogen bonds with water molecules, reducing surface tension and causing condensation to spread into a film rather than form droplets. (2) Inorganic hydrophilic coating (high-end applications) - Composition: Primarily composed of inorganic materials such as silica sol and titania sol, formed into a porous structure via the sol-gel method, utilising capillary effects to adsorb water molecules; - Advantages: High temperature resistance (can withstand temperatures above 150°C), excellent ageing resistance, suitable for long-term high-temperature and high-humidity environments (such as heat pump condensers); - Limitations: Weak colour expression, mostly transparent or light-coloured, lower decorative properties than organic coatings. (3) Composite coatings (functional layering) - Utilises a three-layer structure of ‘primer (corrosion protection) + coloured topcoat (decorative) + hydrophilic topcoat (functional)’, balancing colour diversity, corrosion resistance, and hydrophilicity: - Primer: Epoxy resin or polyurethane, providing adhesion and corrosion resistance; - Topcoat: Polyester or fluorocarbon coating, providing colour and basic weather resistance; - Topcoat: Hydrophilic functional layer, 1–2 μm thick, ensuring hydrophilic performance without affecting thermal conductivity. 3. Performance Optimisation Process: Ensuring Functional Stability- Curing process: High-temperature baking at 180-220°C to cross-link and cure the coating, ensuring stable adhesion of hydrophilic groups and preventing degradation of hydrophilic performance over time; - Surface microstructure control: Using nanoimprint technology to create micron-level uneven structures on the coating surface, increasing contact area with water and enhancing wettability; - Weather Resistance Enhancement: UV absorbers and antioxidants are added to prevent coating degradation caused by sunlight or high temperatures, with hydrophilic performance efficacy lasting up to 8–10 years (air conditioning industry standard). II. Core Characteristics of Colour-Coated Hydrophilic Aluminium Panels: Dual Advantages of Functionality and Aesthetics1. Hydrophilic Core Functionality: Enhancing Equipment Efficiency and Stability- Efficient hydrophobic anti-condensation: Condensate rapidly spreads into a uniform water film on the surface (contact angle ≤30°), rather than condensing into droplets that fall off, preventing droplets from blocking the gaps between heat exchanger fins and ensuring a 15%-20% increase in airflow; - Enhanced Heat Exchange Efficiency: The larger contact area between the water film and air facilitates more thorough heat transfer, improving air conditioning cooling efficiency by 5%-8% and achieving significant energy savings; - Mould-resistant and corrosion-resistant: The rapid flow of the water film reduces moisture retention, lowering the risk of mould growth (mould survival rate decreases by over 60%), while the coating isolates water vapour from aluminium contact, achieving salt spray resistance of over 500 hours. 2. Decorative colour coating: Expanding application scenarios- Colour diversity: Through colour-coated topcoats, pure colours (white, grey, blue, etc.) and matte/high-gloss effects can be achieved, meeting aesthetic requirements for equipment appearance or architectural decoration; - Surface texture options: In addition to traditional flat surfaces, embossing and brushing processes can be combined to add textural decoration while maintaining hydrophilicity, suitable for indoor humid environments (such as bathroom walls); - Customised adaptation: Adjust the coating gloss (30°-80°), colour saturation, and even print simple patterns according to requirements, balancing functionality and design aesthetics. 3. Physical properties: Suitable for harsh environments- Temperature resistance: Long-term operating temperature range of -40°C to 120°C (special coatings can reach 150°C), adapting to temperature fluctuations caused by air conditioning cycles; - Mechanical strength: Coating adhesion reaches Grade 0 (no peeling in cross-hatch adhesion test), scratch resistance ≥3H (pencil hardness), and withstands friction during equipment assembly; - Lightweight: Density is only 2.7 g/cm³, 60% lighter than copper, reducing equipment weight, suitable for mobile air conditioners, vehicle-mounted refrigeration equipment, and other applications. III. Typical application scenarios: from industrial equipment to building decoration1. Refrigeration and HVAC equipment (core application areas) - Air conditioner evaporators/condensers: heat exchange plates for household air conditioners and central air conditioners; hydrophilic coatings reduce condensation residue, improve heat exchange efficiency, and reduce air resistance and noise; - Refrigerator evaporators: Prevents uneven frosting that reduces cooling efficiency; hydrophilic properties accelerate defrosting water drainage, reducing the risk of cabinet corrosion; - Air-source heat pumps: In low-temperature, high-humidity environments, hydrophilic coatings prevent evaporator frosting and blockages, ensuring stable heating performance. 2. Building decoration in humid environments - Bathroom walls/ceilings: Hydrophilic coatings allow water vapour to diffuse quickly, reducing condensation droplets, while resisting moisture corrosion and preventing rust and discolouration of traditional aluminium panels; - Kitchen countertop splashbacks: Resistant to grease and easy to clean, water droplets and grease can be quickly wiped away to maintain a clean surface; - Underground garage ceilings: In high-humidity environments, hydrophilic properties prevent condensation and water accumulation, while decorative colour coatings enhance the aesthetic appeal of the space. 3. Special industrial applications - Dehumidifiers/humidifiers: Core heat exchange components use colour-coated hydrophilic aluminium panels to improve moisture handling efficiency, while colour coatings facilitate identification of internal equipment structures; - Cold chain logistics equipment: The hydrophilic coating on the interior walls of refrigerated vehicles and the side panels of refrigerators reduces condensation adhesion, while antimicrobial additives (such as silver ions) inhibit bacterial growth; - Marine environment equipment: In high salt fog environments, the corrosion-resistant hydrophilic coating protects aluminium from corrosion, making it suitable for marine air conditioning and offshore platform refrigeration equipment. 4. Core differences from ordinary colour-coated aluminium sheets and hydrophilic aluminium foilComparison dimension    Colour-coated hydrophilic aluminium sheet    Ordinary colour-coated aluminium sheetCore Functionality    Hydrophilic anti-condensation + colour decoration    Colour decoration + basic corrosion resistanceCoating Structure    Primer + colour-coated topcoat + hydrophilic topcoat    Primer + colour-coated topcoatHydrophilic Performance    Contact angle ≤30°, long-term stability    Contact angle >90° (hydrophobic)Decorative Properties    Diverse colours, customisable textures    Diverse colours, but no hydrophilic propertiesApplication Scenarios    Decorative applications in humid environments + moderate to low thermal conductivity requirements    Decorative applications in dry environments- Summary Colour-coated hydrophilic aluminium panels, through their composite design combining ‘decorative colour coating + hydrophilic functionality,’ break through the limitations of traditional aluminium panels' ‘single functionality,’ simultaneously meeting aesthetic requirements for equipment or spaces while addressing issues such as condensation, corrosion, and efficiency degradation in humid environments. From the efficient operation of air conditioning heat exchangers to the dry and clean walls of bathrooms, colour-coated hydrophilic aluminium sheets are leveraging their ‘multi-functional’ advantages to become an important functional material in industrial equipment and architectural decoration, driving the deep integration of ‘practicality and aesthetics.’

The following are some factors that will accelerate the corrosion of aluminum sheet: 1.Environmental factors Humidity: A high - humidity environment is one of the important factors accelerating the corrosion of aluminum sheets. When the relative humidity in the air exceeds a certain level (usually about 60%), a thin water film will form on the surface of the aluminum sheet. Various corrosive substances, such as oxygen, carbon dioxide, sulfur dioxide, etc., may be dissolved in the water. These substances react chemically with aluminum, leading to the corrosion of the aluminum sheet. For example, in coastal areas or regions with a long rainy season, the high - humidity environment makes the aluminum sheet more susceptible to corrosion. pH value: Aluminum is prone to corrosion in both acidic and alkaline environments. In an acidic environment, hydrogen ions react with aluminum to produce aluminum ions and hydrogen gas. For example, in an industrial environment, if aluminum sheet comes into contact with acidic gases (such as sulfur dioxide, hydrogen chloride, etc.) or acidic liquids (such as sulfuric acid, hydrochloric acid, etc.), the corrosion will be accelerated. In an alkaline environment, hydroxide ions also react with aluminum to produce aluminate and hydrogen gas. For example, in some environments containing alkaline substances, such as cement, lime, etc., the aluminum sheet is also prone to corrosion. Salt spray: In coastal areas or marine environments, the air contains a large amount of salt, forming salt spray. Chloride ions in the salt spray can accelerate the corrosion of aluminum sheets. Chloride ions have a strong penetrating ability and can damage the oxide film on the surface of the aluminum sheet, exposing the aluminum to a corrosive environment and thus accelerating corrosion. For example, the aluminum sheets used on offshore oil platforms, ships and other facilities are vulnerable to the erosion of salt spray. Temperature: An increase in temperature accelerates the corrosion rate of aluminum sheets. On the one hand, a rise in temperature speeds up the chemical reaction rate, thus accelerating the reaction between aluminum and corrosive substances. On the other hand, a high - temperature environment makes the oxide film on the surface of the aluminum sheet unstable and prone to cracking, thus losing its protective effect on aluminum. For example, in high - temperature industrial environments such as refineries and chemical plants, the corrosion rate of aluminum sheets will increase significantly.  II. Human Factors Mechanical damage: During the transportation, installation, and use of aluminum sheets, if they are subject to mechanical damage such as scratches and collisions, the oxide film on their surface will be damaged, exposing the aluminum to the air and thus accelerating corrosion. For example, during the construction process, accidentally scratching the surface of the aluminum sheet, or colliding with sharp objects during handling, may cause corrosion of the aluminum sheet. Improper cleaning: If the aluminum sheet is cleaned with inappropriate cleaning agents or methods, it may also accelerate corrosion. For example, using acidic or alkaline cleaning agents to clean the aluminum sheet will damage the oxide film on its surface; using rough cleaning tools such as wire brushes will scratch the surface of the aluminum sheet, thus accelerating corrosion. Poor welding: During the welding process of aluminum sheets, if the welding process is improper, such as too high welding temperature or too long welding time, the oxide film on the surface of the aluminum sheet will be damaged, and at the same time, welding defects such as pores and cracks may occur, which will accelerate the corrosion of the aluminum sheet. For example, in some steel structure projects, if the welding parts between the aluminum sheet and the steel structure are not properly treated, corrosion problems are likely to occur.  III. Material factors Impurity content: The impurity content in aluminum sheets can affect their corrosion resistance. If the aluminum sheet contains a relatively high amount of impurities such as iron, copper, and silicon, these impurities will form a galvanic cell with aluminum, accelerating the corrosion of aluminum. For example, some low - quality aluminum sheets, due to impure raw materials and a high impurity content, are prone to corrosion. Alloy composition: Different aluminum alloy compositions also have different sensitivities to corrosion. Some aluminum alloys containing specific alloying elements, such as magnesium, zinc, etc., may accelerate corrosion in specific environments. For example, some high-strength aluminum alloys are prone to stress corrosion cracking in a humid environment. Surface treatment quality: The surface treatment quality of aluminum sheet is crucial to its corrosion resistance. If the surface treatment is incomplete, such as uneven thickness of the oxide film and poor coating adhesion, the aluminum sheet will be more prone to corrosion. For example, the surface treatment process of some low - cost aluminum sheets is simple, and the coating quality is poor, which easily leads to problems such as peeling and blistering, thus accelerating corrosion.
