Transparent Glass Backed Marble Stone Composite Panel for Indoor Decoration
Transparent Glass Backed Marble Stone Composite Panel for Indoor Decoration is a marble stone veneer composited with a glass backing plate. The product is good on lightening performance. The composite panel is formed by glass,stone and epoxy. The glass can be either tempered or laminated and bonded to the stone using a translucent epoxy that does not affect the natural colour of the stone.This method works well with stones of translucent onyx, alabaster or white marble as the pattern of natural veins of the stone will glitter and be transparent under lighting. Such composite panels are used in hotel proscenium, feature walls, elevators and ornamental ceilings.
The two parts are tightly bonded together with high strength glue under high temperature and pressure. The resultant composite panel not only preserves the natural beauty of the granite or marble, it also overcomes inherent properties and characteristics like fragility and heaviness present in natural stones. Composite panels can be produced virtually in any natural stone material including granite, marble, limestone, slate and sandstone.
|The standard composite panel comprising stone veneer with plastic laminated panels reinforced with honeycomb aluminium is 1/2 or 1/3 lighter than solid stone panel. This reduces the dead load of the building. As it is lighter, the erection speed is also improved, especially in high-rise building claddings. There is therefore savings in structural requirements, labour and time. Besides providing stability to the thin layer stone, the fabrication technique eliminates warpage – a natural characteristic often seen in long stone panels. The composite stone panel can be installed on most substrates using a variety of installation methods including adhesion or mechanical fastenings like concealed screws or interlocking channels.
|Better impact resistance, flexural strength and water resistant
|Composite stone panel has better impact resistance and flexural strength due to their backing support. The backing supportpanels can be flexed, making them ideal for a variety of architectural applications. They reduce the fragile and brittle properties of natural stones and can be used in place of natural stones for their aesthetic beauty. In addition, the epoxy skinned composite panel is impervious to water penetration, even with open structured stones such astravertine or limestone.
|Increase stone utilization ratio
|The use of thin stone veneer in composite panels maximizes the usage of natural stone. The utilization ratio is generally about 3 times higher than if the material comprise wholly of natural stone. For example, 1 m3 of raw stone can be used to fabricate up to 135 m2 of composite stone panels compared to about 45 m2 of natural stone panels. This is a more efficient use of limited resources, reduces the exploitation of natural resources and promotes environmental conservation. Furthermore, getting a larger quantity of stone veneer from a single block allows the manufacturer to achieve a more consistent tone and texture in the end-product
|better flexural strength.
|The thin polyester aluminum backing panel is about 2.5 to 4 mm thick and such composite panels are suitable for applications requiring light weight and thinness. It can be used for internal wall claddings, lift interiors and decorative ceilings. Apart from being light weight,the polyester aluminum panels are more even and resistant to corrosion and chemical attack.
The natural stone from the quarry in the form of blocks are cut into thin slabs. They are bonded to backing panels by special resin followed by application of uniform heat and pressure to ensure proper bonding throughout the whole slab. Once the glue has set, the slab is sawn into half and the pieces are polished or honed. Finally, the pieces are cut to size mechanically according to customer’s requirements.
A. Although the technology economizes the use of natural stone, speeds up installation and improves the performance and range of applications, it may not be cost effective in applications involving natural stones with low and medium cost range. However for applications that use high-end luxurious stones like onyx marble or sky blue granite,there are potential benefits and savings as the usage of the more costly raw material is greatly reduced.
B. The strength and performance of the composite stone panel are very much dependant on the manufacturing technology and the quality of resin used. Hence it is important to ensure the right materials and suppliers are chosen to supply the product.The choice of installation methods e.g. mechanical fastening or by adhesive glue, requires appropriate skilled labour to ensure the effectiveness of the installation.
C. Hence it may be necessary to ensure there are adequately trained workers to carry out the installation works before considering light weight composite stone panels.
They are used in a wide range of applications like exterior and interior wall claddings,elevators, over-lays, counter-tops and other special applications.
