TiO₂ Photocatalytic Aluminum Honeycomb Filter Panels for VOC, Formaldehyde and Odor Removal

Custom Aramid Honeycomb Core

서론

1. Our TiO₂ photocatalytic aluminum honeycomb filter panels combine a lightweight aluminum honeycomb substrate with a high‑activity titanium dioxide coating to deliver efficient air purification and VOC decomposition. The thin‑wall honeycomb structure offers a very large specific surface area and low pressure drop, allowing airflow to pass through smoothly while maximizing contact with the active TiO₂ layer. Under UV or suitable visible light, the photocatalyst decomposes formaldehyde, benzene, VOCs, smoke and odors into harmless CO₂ and H₂O, making it ideal for continuous purification in HVAC systems and air treatment equipment.

2. The aluminum honeycomb core provides excellent mechanical strength, corrosion resistance and thermal conductivity, ensuring long service life and stable performance in both residential and industrial environments. We offer customized cell sizes, thicknesses and panel dimensions, as well as different TiO₂ formulations and coating loads to match your light source, air volume and target pollutants. These catalytic honeycomb filter panels are widely used in central air conditioning, air purifiers, coating lines, parking garages, hospitals, offices and other places requiring efficient, low‑maintenance air cleaning.

   사양

   유형	TiO₂ catalytic aluminum honeycomb substrate / filter panels / blocks; supplied as bare aluminum honeycomb with TiO₂ coating or assembled in framed filter modules for VOC, formaldehyde, odor removal and photocatalytic air purification in HVAC, indoor air quality, and industrial exhaust systems.
   Structure	Lightweight aluminum honeycomb core with thin‑wall, straight‑through cells (typically hexagonal or square), coated on the internal surfaces with a titanium dioxide (TiO₂) photocatalyst layer to provide very high specific surface area, low pressure drop, and efficient contact between pollutants and active sites.
   Base Material (Substrate)	Aluminum honeycomb made from aluminum foil (commonly 3000 or 5000 series alloys) for low weight, good formability and corrosion resistance; other aluminum grades available according to mechanical or environmental requirements.
   Catalyst Grade (TiO₂)	High‑activity titanium dioxide photocatalyst (typically anatase‑rich or mixed‑phase TiO₂); optional doped or modified TiO₂ formulations available to enhance activity under UV or visible light and to target specific VOCs, formaldehyde, and odor compounds.
   Cell Size	Typical cell size from about 3 mm to 10 mm (e.g., 1/8″, 3/16″, 1/4″); smaller cells increase geometric surface area and catalytic efficiency, while larger cells reduce pressure drop and are suitable for higher flow rates or systems sensitive to airflow resistance.
   Cell Shape	Standard hexagonal cells or square/rectangular channels depending on the aluminum honeycomb specification; special geometries and perforation schemes available to meet airflow, pressure‑drop, and installation requirements.
   Foil Thickness	Aluminum foil thickness typically from about 0.03 mm to 0.1 mm, selected to balance strength, rigidity, weight, and pressure‑drop performance; thicker foils used where higher mechanical strength or larger panel sizes are required.
   Overall Thickness Range	Honeycomb core thickness typically from about 5 mm to 100 mm; finished catalytic panel thickness depends on core height, frame profile, and optional protective meshes, usually in the range of 10–80 mm for HVAC and air purification systems.
   Panel Size (L × W)	Panels available from small cut pieces for equipment integration to large‑format modules (e.g., up to approx. 1200 × 1200 mm or as required by air handling units); special sizes and custom framed cartridges can be supplied according to system design.
   Coating Loading	TiO₂ coating weight and thickness can be adjusted to application needs, balancing catalytic activity, adhesion, and pressure drop; typical loadings designed to maximize surface coverage without blocking channels or significantly increasing airflow resistance.
   Mechanical Properties	Aluminum honeycomb provides high stiffness‑to‑weight ratio and good compressive strength; the catalytic layer is firmly bonded to the substrate to resist dust blow‑off and normal cleaning or maintenance operations in HVAC and industrial systems.
   Photocatalytic Performance	Under UV or suitable visible light irradiation, TiO₂ generates reactive species (•OH, •O₂⁻) that oxidize VOCs, formaldehyde, odors, and other organic pollutants into CO₂ and H₂O; performance depends on light intensity, wavelength, contact time, pollutant concentration, and catalyst formulation.
   Thermal & Airflow	Excellent airflow characteristics due to straight‑through honeycomb channels with low pressure drop; aluminum substrate offers good thermal conductivity, helping to dissipate heat and maintain stable catalytic performance over extended operation.
   Surface Finish (Core)	Aluminum honeycomb substrate can be supplied in mill finish or pre‑treated (e.g., cleaned, chemically etched) to enhance TiO₂ coating adhesion; edges can be cut and sealed or framed to suit mounting, sealing and contamination‑control requirements.
   Surface Finish (Panels)	With frame or casing: galvanized steel, aluminum, or stainless steel frames; optional protective meshes, pre‑filters, or downstream filters can be added; external surfaces can be painted or treated according to corrosion‑protection or aesthetic requirements.
   Bonding & Coating Process	TiO₂ typically applied as a slurry or sol–gel coating followed by drying and calcination/curing to ensure strong adhesion and stable photocatalytic activity; additional binders or additives may be used to improve mechanical robustness and resistance to dust and moisture.
   Operating Conditions	Designed for air treatment at ambient to moderately elevated temperatures typically encountered in HVAC and industrial exhaust (exact limits depend on frame, seal materials, and TiO₂ system); requires UV or suitable visible light source for photocatalytic activation.
   Corrosion & Chemical Resistance	Aluminum honeycomb with appropriate surface treatment and frame selection offers good resistance to typical indoor air and many industrial exhaust environments; specific coatings or materials can be selected for more aggressive atmospheres or higher humidity conditions.
   Processing & Forming	Panels and cores can be cut, framed, and assembled to fit existing ducts or equipment housings; modular design allows parallel or series arrangement to meet required air volume and purification efficiency.
   Dimensional Tolerances	Controlled cell size, core thickness, and panel dimensions; tolerances can be specified according to project requirements or relevant HVAC/industrial standards to ensure proper sealing, low bypass, and stable installation.
   Standards & Reference	Manufactured with reference to applicable HVAC, air filtration, and catalyst substrate standards (e.g., EN, ISO, and industry guidelines) regarding mechanical integrity, pressure drop, and performance testing where requested.
   Application Range	Central air‑conditioning systems, air purifiers, clean rooms, hospitals, offices, shopping malls, parking garages, printing and coating lines, VOC and odor control systems, kitchen exhaust treatment, and other applications requiring continuous photocatalytic air purification.
   Customization	Custom cell size, TiO₂ formulation and loading, core thickness, panel size, frame type, and connection method; panels can be designed according to drawings, CAD models, and specific airflow and pollutant‑removal requirements.
   Form of Supply	Supplied as bare TiO₂‑coated aluminum honeycomb blocks, cut‑to‑size catalytic plates, or fully framed filter modules ready for installation in air handling units or dedicated reactors; optional pre‑filters and mounting accessories available.
   Packaging	Panels and cores packed with edge protection and moisture‑resistant wrapping; suitable cartons or wooden crates used to prevent mechanical damage, contamination, or coating abrasion during transport and storage; special packaging can be provided for export or high‑cleanliness applications.
