Surface Anodized Aluminium Honeycomb Roof Panel for the Assembled Floating Roof of the Oil Tank

Product Description

Surface Anodized Aluminium Honeycomb Roof Panel for the Assembled Floating Roof of the Oil Tank is a special surface treated aluminum honeycomb panel which can be used on the floating roof oil tank. The surface can sustain oil corrosion while the cost is competitive.

Internal floating roofs (IFR) first found their place in the oil industry to conserve product and prevent fires. Later, they were required for controlling hydrocarbon emissions into the atmosphere, as regulated. An IFR tank has a floating deck below a fixed roof. The floating deck rises and falls along with the liquid level, leaving no room for a vapor zone. Depending on the product and the plant environment, floating roofs are readily available in steel or aluminum. Fiber reinforced plastic can also be an option in highly corrosive environments.

Among various types of IFRs available, aluminum internal floating roofs are widely used due to their cost effectiveness. Among them, full contact honeycomb-sandwich roof panel, a honeycomb-sandwich roof is in full contact with the product with a honeycomb core sandwiched between aluminum sheeting.

Milled finish means the aluminium surface should not do any treatment but just leave it as it comes out from the plant. Milled finish has the following advantages: 1. save the material and process cost; 2. can support further process; 3. suitable for many specific application field.

For the edge open solution, as the aluminium honeycomb panel will be used in the downstream production process for change the size such as cutting and carving, the edge treatment before use is a waster. It is not necessary to make the edge closed so that the cost and time can saved. Also, for the installation method, there will be supporting frames applied to the aluminium honeycomb panel and after installation, the edge will be covered by the installation frame, it is not necessary to make the edge sealed.

General Description

Aluminum honeycomb panel is a bonded sandwich structure system of two surface aluminium plates and one honeycomb cores with a special purpose adhesive. Industrial used aluminium honeycomb panel will add some more processes such as surface treatment, edging, embedding, carving and so on to make the panel suitable for special conditions. It has been widely used by the industries of civil construction, transportation, exhibition, signage, elevator, clean room etc. The honeycomb technology is from aerospace technology. The whole production process is finished in the modern factory, using hot pressing or vacuum pressing technology. Due to the high thermal conductivity between the aluminum plates and honeycomb, it is synchronized the thermal expansion and contraction of the inside and outside aluminium material. There are small holes on the honeycomb core foil wall so that the air is free of flowing inside the panel box. Furthermore, sliding mounting buckle system does not cause structural deformation during thermal expansion and contraction.

Features

The center material is aluminum hexagonal honeycomb with a small density (about 3 to 7 kg per square meter), about 1/5 of the weight of wood with the same area and thickness, 1/6 of the glass, 1/7 of solid aluminium, which greatly reduced the building load and construction cost. Thanks to the air contained in the core, the panel can be sound and thermal insulated. Because of no combustible material contained, the fire rating can be at least B1 level. The panel performs well also on waterproof, moisture-proof, no harmful gas release, with a high unit mass of the specific strength and stiffness, not easy to deformation, completely overcoming the collapse and deformation in the center area if with large panel. The panel edge can be cut depending on real conditions. The PVDF coating can guarantee the product life more than 30 years.

After surface treated with corrosion resistant fluorocarbon resin, it can be widely used on curtain wall, roof, large façade, signs and interior decoration. The front plate of the aluminum honeycomb panel is painted with E. C. C. A. quality standards PVDF fluorocarbon paint with ordinary color or metallic color, so the surface has excellent weather resistance.

In case of heavy rain, there is particularly large noise when the raindrops hit the aluminum veneer or aluminum-plastic panel, while honeycomb panel can avoid this situation. Aluminum honeycomb panels are generally made of fluorocarbon coated aluminum plates. The continuous roller coating with PVDF material is the most important point to avoid color difference and flat coating film. Based on this, it can keep the exterior building with bright color for long time.
