Shockproof ACM Composite Panels

Fire Testing Aluminium Composite Panels 1220 X 2440 X 4mm For Wall Cladding

Key highlights incorporate a totally smooth and level surface of the panel. The component of the structure that is significant for the evenness is the covering. Besides, the Fluorocarbon (PVDF) has another significant job, climate obstruction. The highlights of fire-evaluated aluminum composite panel items represent its wide region of use. Today, we can even discuss warmth and sound protection, just as fire obstruction on account of various coatings, for the most part the PVDF. This opens new skylines with respect to the utilization of the facade aluminium composite panel panels. Thus, territories of the utilization of the Fluorocarbon (PVDF) aluminum composite panels are wide. Today, we, for the most part, use it as a crude material in various types of enterprises. Plus, it is utilized for notice sheets and claddings, exteriors, for example, outsides of structures.

1. Material composition

MEGABOND™ is an Aluminum Composite Material (ACM) for the construction industry worldwide. It is not only a reasonable alternative to solid aluminum sheet, but also an individual material characterized by its own unique features. Its lightweight, high rigidity, excellent flatness and long lasting coating qualities are just what the construction industry has been looking for.

MEGABOND™ /fr is an aluminum composite material (ACM) with a fire-retardant core suitable for exterior and interior cladding, soffit linings and roof covering in new buildings and retrofit applications.

MEGABOND™A2 is an aluminum composite material (ACM) with a high fire-retardant core suitable for exterior and interior cladding, soffit linings and roof covering in new buildings and retrofit applications.

MEGABOND™, MEGABOND™/fr, MEGABOND™ A2 are often simply referred to as “MEGABONDs” or “MEGABOND products” in this brochure, if the context is applicable to both products. We will use the respective MEGABOND, MEGABOND/fr, MEGABOND A2 if we need to mention each of them separately.

The core of MEGABOND is black and those of MEGABOND/fr, MEGABOND A2 are gray or white containing a mineral. Thus, we can discern each product by appearance. The total thickness is 3, 4 and 5mm.

Fig. 1-1 Composition of MEGABONDs

Topside of MEGABONDs is finished with a paint called LITONG™-based fluoropolymer paints as standard and backside is finished with a thin polyester coating (wash coating) or a service coating. The topside is covered with a protective Film.

Total thickness: 3, 4 and 5 mm ( MEGABOND, MEGABOND/fr and MEGABOND A2),

2.Production process

The production process of MEGABONDs consists of two production lines: a coil coating line and a laminating line. In the coil coating line, LITONG-based fluoropolymer paints are applied to continuous aluminum coils. In the laminating line, the low-density polyethylene or the mineral-filled core is laminated between two coated coils, resulting in the finished composite material.

After laminating, the finished products are packed in wooden cases and shipped to customers’ workshops. Thus, MEGABOND products are shipped as flat panels and processed in local workshops according to project drawings.

3.Features

MEGABONDs have a number of unique features:

Flatness: The continuous laminating process results in excellent flatness of the panel.

Color uniformity: The coil coating process ensures complete color consistency.

Rigidity: As one of the attributes of ACM, MEGABONDs are light and strong sheet materials, reducing the weight by 9% (MEGABONDA2) or 15% (MEGABOND/fr) compared to solid aluminum sheets with equivalent rigidity.

Workability: MEGABONDs are easy to cut, bend, groove and shape with regular aluminum working and woodworking machines and tools.

Fire safety: With the fire-retardant core, MEGABOND A2 and MEGABOND/fr meet fire code requirements in several countries including Europe, North America, Middle East and Japan without any restrictions.

(1)Flatness

(2)MEGABONDs are very flat. Generally speaking, ensuring the flatness of sheet materials is not easily realized. Solid aluminum sheet, for example, has a slight distortion stemming from its rolling process: buckles, edge waves and overall warping are common.

MEGABONDs are extremely flat due to the thinness of the aluminum sheets (0.5mm) and our lamination process in which most of such distortions are eliminated.

(1) Rigidity

MEGABONDs are highly rigid compared to solid aluminum metal sheets. As shown in Fig. 1-4, two sheets of aluminum skin behave like a small H-section when pressure is applied on the panel. Consisting of 2 sheets of 0.5mm thick aluminum, MEGABONDs 4mm thick deliver the rigidity equivalent to an aluminum sheet of 3.3mm thick.

Table 1-1 Comparison of rigidity between MEGABONDs and solid aluminum sheet

Note 1: How to read the above table: MEGABOND /fr 4mm is equivalent to aluminum sheet 3.3mm in rigidity. Hence, the weight percent of MEGABOND to solid aluminum is 85%.

Note 2: MEGABOND A2 is heavier in weight than MEGABOND /fr due to high mineral content in the core.

(3) Workability

The workability of MEGABONDs is one of its outstanding features. It can be cut with circular saws. It can be folded after grooving with a groove cutter or a router. It can be bent with a 3-roll bender and press

brake. For joining, we can choose the most suitable method from several alternatives. For details, refer to Section 3 “Fabrication and installation.

(4) Fire safety

MEGABON A2 MEGABOND/fr, MEGABOND A2 fire-safe materials which pass mandatory requirements for exterior and interior in several countries. Though the core material does contain a small amount of combustible polyethylene, the main ingredient of the mineral does not permit the proliferation of flame and restricts the development of smoke detrimental to evacuation activities.

MEGABONDs are composed of two aluminum skins which retard the spread of fire. Extensive fire tests have been performed on MEGABOND/fr, MEGABOND A2 in accordance with requirements in various countries. Refer to Section 2 Characteristics” for details.
