In a sense, renewable resources are non-renewable resources, recycling zinc ash, non-renewable resources are renewable resources, but they are different from each other conversion time fills renewable resource regeneration cycle is short, you do not need hundreds of years crustal movement, rather than a renewable resource, need to go through the hundreds or even millions of years to form and deposit, so in the sense that both can be conducted into each other, but with the process of modernization of human pollution intensifies, many Originally resource is a renewable resource recycling zinc ash, already facing the risk of non-renewable resources become like water pollution is threatening the water quality of rivers and lakes, is air pollution and other industrial emissions. Renewable energy refers to the period of time is inexhaustible resources, strictly speaking, not a permanent resource. But also limited use, do not think it is a renewable energy use without limits. Most of the renewable energy sources are actually other form of storage of solar energy. People began to see the importance of renewable energy and to take certain measures to protect non-renewable resources. Small aluminum density (ρ = 2.7g / cm3), about 1/3 of iron, low melting point (660 ℃), aluminum is face-centered cubic structure in Shandong zinc ash recycling, it has a high plasticity (δ: 32 ~ 40%, ψ: 70 ~ 90%), ease of processing, can be made into a variety of profiles, sheet metal, good corrosion resistance. But the strength of aluminum is very low, annealed σb value of approximately 8kgf / mm2 Anhui zinc ash recycling, it is not suitable for structural materials. Through long-term production practice and scientific experiments, people gradually adding alloying elements and heat treatment and other methods to strengthen the aluminum, which has been a series of aluminum alloy. Add some elements to form the alloy while maintaining the advantages of lightweight aluminum with high intensity while, σb values ??of up to 24 ~ 60kgf / mm2. This makes the "specific strength" (strength and weight ratio σb / ρ) is better than a lot of steel, an ideal structural material, widely used in machinery manufacturing, transportation machinery, power machinery and aviation industries, the aircraft fuselage , skin, compressor, etc. often aluminum to reduce weight. Aluminum instead of steel materials, welding, structural weight can reduce more than 50%. Zinc ash recycling _ _ Shengxin Henan zinc ash recycling scrap metal recycling (certified merchants) recovered from the Linyi City Shengxin scrap metal Limited. Road Zhiyuan, temper forward. Linyi City Shengxin scrap metal recycling Ltd. (shengxin.tz1288.com) aims to become and you win symbiosis, strategic partners to move forward, the more determined to become the most influential of the scrap metal business, and you leap to jointly Success!
