韩国钢铁制造商 东国制钢(Dongkuk Steel) 旗下子公司 Dongkuk CM 推出全球首款专为双面光伏屋顶系统设计的 超高反射彩钢板。
彩钢板(预涂或彩涂钢)是一种兼具结构强度与装饰效果的建筑材料,广泛用于屋顶、墙体及多种建筑外饰。其通过有机涂层提升耐久性、美观性与抗腐蚀性能。
Dongkuk CM表示,新型屋面材料基于公司自主研发的 Soft-GLX三元防腐镀层技术,是全球首款针对双面光伏屋顶系统设计的超高反射彩钢板。
该产品通过精确调整锌、铝、镁比例,提高了耐腐蚀性和可加工性,防止在折弯施工中产生损伤。公司称:“SLX技术已获韩国、日本及多国专利。涂层可保持20年品质,镀层可维持30年。”
与传统屋面材料 50%至60%反射率 相比,新产品的 总太阳反射率(TSR)达80%至85%。公司表示:“应用后可使双面光伏组件的发电效率提高约30%。”
此外,新产品采用双层结构设计,将受光正面与贴合玻璃棉的背面分离,从而增强耐腐蚀性。
东国CM技术研究中心负责人 崔宇灿(Choi Woo-chan) 表示:“这是一种新一代高端建筑材料,具备卓越的反射率与防腐性能,即使在极端环境下仍能稳定运行。同时还可实现‘冷屋顶’效果,随着反射率提升,有助于降低屋顶温度、节省能耗。”
