PVDF marble grain aluminium sheet description

Table Of Contents SHOW

PVDF marble grain aluminium sheet is commonly used in curtain wall decoration. The texture is the same as that of the stone slab, it is a perfect substitute for the stone slab for construction. PVDF marble grain aluminium sheet’s construction technology is simple, easy to install, while its service life is longer than that of stone slabs.

It is much lighter than stone slab for same square meters, and it can be recycled again. For some special purposes, it can be deep processed into stone grain honeycomb aluminum plate, stone grain heat insulation aluminum plate, etc., and the surface is sprayed with marble and other stone grain lines. STEK is PVDF marble grain aluminium sheet manufacturer with low price. All products can pass the national standard test and are used by many large projects such as Beijing and Shanghai.

PVDF marble grain aluminium sheet can fully meet the design requirements and can be made into a shape that stone can’t.

The coating of PVDF marble grain aluminium sheet has many excellent characteristics such as long life, fingerprint resistant, antibacterial, thermal insulation and corrosion protection, self-cleaning, anti-fading, high strength etc .

PVDF marble grain aluminium sheet Color change performance test standard

According to GB/T 9276, after the sample has been exposed for 10 years, the discoloration with ?E of not more than 5NBS compared with the original color is qualified. It can be directly measured with a computer color imeter, and the average value of the points is taken.

The measurement method is as following: after exposure, the sample is exposed to clean water and a damp cloth to remove the surface ash, and then the color change is measured.

At the same time, the same batch of unexposed samples is measured as a reference, and the color difference between the two is compared. Rinse the sample gently with water to remove the dust accumulation. It is not allowed to wipe or polish hard to avoid removing the powder.

Advantages of PVDF marble grain aluminium sheet

What are the advantages of PVDF marble grain aluminium sheet?

  • Long service life, forming an aluminum oxide film with the atmosphere to prevent further corrosion.
  • Energy saving and environmental protection, 100% can be recycled, and high recycling value, energy saving and environmental protection.
  • Recycling and preserving value, the value of recycling is 80% of the value of aluminum ingots, currently 9,000 yuan per ton. Color steel plates have almost no recycling value.
  • Low maintenance cost, corrosion resistance, no rust, and low maintenance cost.
  • The cost of construction is low, the weight is light, and the density is 2690KG per cubic meter, which reduces the weight and reduces the weight cost of the overall building structure material.
  • Fire safety, low melting point of 650 degrees Celsius, when fire happens , The roof is easy to burn through, it is helpful for fire fighting, and it can reduce the loss caused by the fire, and avoid the horizontal spread of the fire.
  • Various appearances, diversified surface treatments, hammering, embossing, anodizing, electrophoresis, painting, drawing, and frosting.
  • Additional benefits, no rust, no dust, no water, to improve the production environment, and provide an effective guarantee for product quality. It will not stop work and production due to replacement of wall and roof, increasing production efficiency.
