Peru will build an eco-city of 2,500 hectares that can accommodate 20,000 inhabitants in the desert area near the city of Paragas in the province of Ica. According to local media reports, the city named “Paragas Ecological Paradise†will use solar energy and wind energy as the main energy sources, and residents in the city will use biogas to cook. To reduce pollution, fossil fuels cannot be used in any vehicle driving in the urban area. According to the plan, the "Paragas Ecological Paradise" will be divided into three regions: agriculture and animal husbandry areas, residential living areas, and ecological villa areas for visitors to stay temporarily. Local agriculture is dominated by the cultivation of grapes, peppers, jasmine, olives, asparagus, etc., and grape as raw material is the priority for the development of Pisco wine brewing industry. All crops are not allowed to use chemical fertilizers and pesticides to ensure that the products produced are green foods. Livestock husbandry is based on raising chickens, ducks, sheep, and cattle, and a horse farm opened to tourists is set up. These agricultural and pastoral products mainly meet the needs of the residents of the eco-city. In the residential area, a 30-meter-wide central street is planned to be laid out, and a 6-meter-wide green belt is established in the middle to plant trees that are conducive to clean air. Peru is an earthquake-prone country, so residential circular houses will use seismic technology. The idea of ​​the "Paragas Ecological Paradise" project began in 2009 when teachers and students from the tourism school belonging to the University of St. Martin in Peru drafted the project during a survey and study in the Pisco region. This huge project is expected to require investment of 170 million U.S. dollars. The Paragas Eco-City Association is applying for assistance from some international organizations. According to the plan, this eco-city will start construction on January 5, 2011 and be completed in 2014.
Anodizing treatment is a surface finishing process for aluminum that forms a protective oxide layer on the surface of the metal. The process involves immersing the aluminum material in an electrolytic solution and passing an electric current through it. This creates a uniform and durable oxide coating that enhances the corrosion resistance and aesthetic appeal of the metal.
There are two main types of anodizing treatment: sulfuric acid anodizing and hard anodizing. Sulfuric acid anodizing is the most common type and produces a thinner, more decorative layer of oxide coating, while hard anodizing results in a thicker, harder, and corrosion-resistant layer that is ideal for industrial and automotive applications.
Anodizing treatment provides numerous benefits to aluminum products. It increases their resistance to corrosion and wear and tear, making them suitable for use in harsh environmental conditions. The process also enhances the strength and durability of the metal, extending its lifespan and reducing the need for maintenance.
Another advantage of anodizing treatment is its ability to add color and texture to aluminum products. Different dyes can be added to the electrolyte solution to produce a range of colors, from bright and vibrant to more subdued tones. Additionally, different textures and finishes can be achieved through specialized anodizing processes, such as matte anodizing or brushed anodizing.
Anodizing treatment is commonly used in various industries, including aerospace, automotive, construction, and consumer goods. It is an eco-friendly process as it uses no hazardous materials and produces minimal waste. However, it is important to note that anodizing treatment may affect the dimensional accuracy of the product and may mask defects that are present on the surface of the material.
Overall, anodizing treatment provides an effective way to enhance the functionality and appearance of aluminum products. As research and innovation continue to advance, even more advanced and innovative applications of anodized aluminum are expected to emerge.
