Aluminum Open Cell Foam for Flooring Panels

Product Description

Henan Chalco aluminum uses open cell aluminum foam technology and adopts the innovative preparation process. The aluminum alloy matrix can be arranged uniformly, densely and regularly into spherical cavity. The diameter of the cavity is controllable, and the pore diameter is interconnected. The specific surface area of 10-45cm2/cm3 is much larger than that of the closed cell and other processes, so its application performance is superior.

According to the cell size, there are three types:

1. Large cell---open both sides

The shiny silver skin on both sides of this low density materials is removed to create a translucent panel. This panel is extremely lightweight and allows light to pass through. All chalco aluminum foam panels are highly reflective; however the bottom of this panel may be even more than others; sharply reflecting light and even picking up the colour of well lit material at a reflective angle to the panel.
Large cell--open one side
The shiny silver skin of the large cell is removed and the cells underneath are exposed. This creates a surface that has been described as appearing like an " aluminum sponge". This is a low density material resulting in large, deep open cells.

1. Middle cell---open one or two sides

These Middle cell aluminum foam panels are created by removing the surface on one side or both sides of the panel, through a special blasting process. The cells below the skin are exposed. This surface consists of a series of middle cell open areas and swirling solid areas, which mingle together to create an appearance described as similar to the surface of the moon or a frozen porous lava flow.

1. Small cell----Open one or two sides

As per the middle open cell product, this small aluminum foam panel is created by removing the surface on one of the sides of the panel or both sides, through a special blasting process. Cells below the skin are exposed. This surface consists of a series of small open areas and swirling solid areas. They mingle together to create an appearance described as similar to the surface of the moon or a frozen porous lava flow.
Through hole foam aluminum is widely used in noise reduction, noise reduction, impact prevention, explosion protection, heat insulation and so on. It is used for making bumper cars, flooring, doors and ceiling materials, mufflers, commercial floor, box, chariot armor, and safety warehouse.
Through hole foam aluminum is also widely used in rail transit and highway noise barriers.
Through hole foam aluminum is also used to spread noise, noise, hull collision, explosion proof overtime, luxury sound insulation wall and so on.
Through hole foam aluminum is also used in building decoration curtain wall, ceiling ceiling and so on.
The aluminum foam is also used in the noise reduction and electromagnetic shielding of the telecommunication room, which has great effect on reducing the pollution of electromagnetic radiation.
