Recently, Professor Zhang Qiangqiang, a professor at Civil Engineering College of Harbin Institute of Technology, and some researchers from American universities made use of 3D printing technology to prepare the world's lightest material - ultra-light graphene airgel. The material has a complex microstructure with a density as low as 0.5 kg / m 3, which is roughly 1/1600 of the density of rice in conventional environments (about 800 kg / m 3), less than the air density (about 1.2 kg / m 3) 1/2. In recent years, the rapid development of 3D printing industry, one of the more compelling areas is the application of graphene materials in 3D printing. Zhang Qiangqiang and other researchers after repeated tests, for the first time in the international community with floating suspended topological pure three-dimensional graphene structure can be tailored design. Popularly, it uses a mixture of graphene oxide and water as "ink" and 3D-prints it on a surface by dripping at a temperature of -25 ° C. So that every layer of print will be frozen, and then printed with the support of ice to the next layer, so as to build ice as a space "stent" structure of the three-dimensional airgel. The researchers said that graphene materials prepared by this method have broad application prospects in the fields of multifunctional materials, flexible electronic devices, energy storage units, sensing devices, biochemical catalytic carriers, supercapacitors and the like. PPGL(Pre-Painted Galvalume) PPGL is a versatile and reliable coated steel product that offers excellent corrosion resistance, aesthetic appeal, and durability. Its wide range of applications and benefits make it a popular choice in the construction and manufacturing industries. ppgl,ppgl coil,ppgi ppgl,ppgl steel coil,color coil ppgl Wuxi Shengshu Metal Co., Ltd. , https://www.wuxissmetal.com
PPGL stands for Pre-Painted Galvalume, which is a type of coated steel product. It is a combination of a Galvanized Steel substrate (galvalume) and a pre-painted coating applied on top of it. The galvalume substrate is made by coating steel with a zinc-aluminum alloy, which provides excellent corrosion resistance.
PPGL is widely used in various industries, including construction, automotive, appliances, and more. Here are some key features and benefits of PPGL:
Corrosion Resistance: The galvalume substrate in PPGL provides superior corrosion resistance compared to regular galvanized steel. This makes PPGL suitable for applications where exposure to moisture, chemicals, or harsh weather conditions is expected.
Aesthetic Appeal: PPGL comes with a pre-painted coating, allowing for a wide range of colors and finishes. This enhances the aesthetic appeal of the finished products, making them visually appealing and versatile for different design requirements.
Durability: PPGL offers excellent durability due to its galvalume substrate and the additional protective layer of pre-painted coating. It can withstand various environmental conditions, including UV radiation, abrasion, and impact, ensuring a long lifespan for the coated steel product.
Easy Maintenance: The pre-painted coating on PPGL makes it relatively easy to clean and maintain. The coating helps to resist dirt, stains, and debris, allowing for simple cleaning with mild detergents or water.
Formability: PPGL retains the formability and flexibility of the underlying steel substrate, making it suitable for various manufacturing processes such as bending, roll forming, and stamping. This allows for the production of a wide range of products and components with different shapes and sizes.
Energy Efficiency: PPGL often features a reflective surface due to the pre-painted coating. This reflective property helps to reduce heat absorption, contributing to energy efficiency and potentially lowering cooling costs in buildings or appliances.
Sustainability: PPGL is a sustainable option as it utilizes a galvalume substrate, which is made with a significant portion of recycled materials. Additionally, the pre-painted coating is typically applied in an environmentally friendly process, and PPGL itself is recyclable at the end of its useful life.
