Other Aluminium Extrusion Products Aluminium ceiling extrusion is a process of manufacturing aluminium ceiling panels by extruding them through a die. Extrusion is a process in which a material is forced through a die to create a specific shape or profile. In the case of aluminium ceiling extrusion, the aluminium is heated and then pushed through a die to create a panel with a specific shape and size.

1. INTRODUCTION:
This is Electric control Whiteness Testing Machine.
Whiteness Testing Machine is mainly used to test the whiteness of diversified objects such as paper and board, pulps and chemical fiber, textile, plastic, ceramic, enamel, fecula, salt, white cerement, porcelain clay and French chalk, etc. It can also be used to test the optical performance of sheet materials, for example, opacity test.
2. APPLICATIONS:
Paper, Board, Pulps, Chemical fiber, Textile, Plastic, Ceramic, Enamel, Fecula, Salt, White cerement, Porcelain clay and French chalk etc.
3. STANDARDS:
ISO 2469, ISO 2470, ISO 2471, GB/T 7933, GB/T 7974, GB/T 8940.2, GB/T 1840, GB/T 2913, GB/T 13025.2, GB/T, 1543, ISO 2471, GB/T 10339, GB/T 5950 etc.
4. FEATURES:
1). Measure the Blue Reflectance Factor (R457) of samples. Blue Reflectance Factor is so called "Blue Whiteness" or "ISO Brightness".
2). Analyze the sample to find out whether it contains any fluorescent brightener. If so, measure the fluorescent whiteness further, namely whitening rate.
3). Measure the opacity, transparency, light scattering coefficient and light absorbing coefficient.
NO.

The extruded aluminium ceiling panels are lightweight, durable, and easy to install. They can be used in a variety of applications, including commercial and residential buildings, hospitals, schools, and other public spaces. Aluminium ceiling panels are also available in a range of finishes, including powder-coated, anodized, and painted.
Aluminium ceiling extrusion is an efficient and cost-effective way to manufacture high-quality ceiling panels. The process can be automated, which reduces labor costs and increases production efficiency. Additionally, aluminium is a recyclable material, which makes it an environmentally friendly choice for ceiling panels.
