一个反常识的知识点：钢“生锈”，反而是好事？

Core Viewpoint - The development of "Danxia Steel®" by Baowu Steel is a significant innovation aimed at addressing the challenges faced by photovoltaic (PV) installations in harsh desert environments, particularly regarding the durability and maintenance of steel supports [7][19]. Group 1: Industry Challenges - Desert regions are ideal for large-scale solar power plants due to abundant sunlight and vast land, but they present severe environmental challenges that can significantly reduce the lifespan of conventional steel supports [3][5]. - Ordinary galvanized steel supports can suffer over 30% reduction in lifespan due to corrosion from wind, sand, and saline soil, leading to increased maintenance costs and operational difficulties [5][16]. Group 2: Innovation in Materials - "Danxia Steel®" is a specially developed weather-resistant steel that utilizes a protective rust layer to prevent further corrosion, effectively allowing the material to "rust" in a controlled manner to protect itself [7][9]. - This innovative steel has a denser and stronger rust layer compared to traditional weather-resistant steels, enhancing its durability in extreme conditions [10][13]. Group 3: Benefits of Danxia Steel® - The protective rust layer formed on Danxia Steel® acts as a robust barrier against corrosive elements, eliminating the need for additional coatings and maintenance throughout its lifecycle [16]. - With a thickness of only 1.5 to 1.8 mm, Danxia Steel® is 20% lighter than traditional materials, facilitating easier transportation and installation while also reducing carbon emissions by 35% during projects [17]. - The successful application of Danxia Steel® in various photovoltaic projects across different terrains demonstrates its reliability and effectiveness in combating the harsh conditions of desert environments [19].
