隆基绿能中国分布式业务市场部负责人钱鑫介绍了Hi-MO X10防眩光产品。隆基Hi-MO X10防眩光组件不但具备 防眩光功能，而且还拥有强大的防起火、防积雪能力。 4月23日，在2025中国民航技术装备及服务展上，隆基绿能（601012）发布全球首款机场专用Hi-MO X10防眩光组 件，为机场光伏建设提供全新解决方案。 清华大学建筑学院副院长林波荣在主题演讲《低碳绿色机场关键技术研究及实践案例分享》中表示，在"双碳"背 景下，急需跨学科思路，以低碳和绿色为导向，突破和创新机场和航站楼规划设计运维的理论、方法、技术和范 式。如果仅因为眩光问题而导致机场无法安装光伏电站，不但会加大机场碳排放方面的压力，而且还会导致机场 优质屋顶的资源浪费。 国家太阳能光伏产品质量检验检测中心(CPVT)副主任朱晓岗在主题演讲中表示，减少光伏组件眩光，实质是降低 组件表面反射光的最大亮度值，方法是增加反射光的分散面积，最终通过玻璃结构设计、电池片结构设计等方式 有效地降低眩光度。 国家太阳能光伏产品质量检验检测中心(CPVT)对Hi-MO X10防眩光组件的防眩光性能进行了测试。测试结果显 示，采用BC技术的隆基Hi-MO X ...

如何定义高纯石 揭秘石英界的"大熊猫" 高纯石英砂 在石英界的广袤天地中,高纯石英砂犹 如"大熊猫"般珍稀。其产量稀少,制 备过程更是挑战重重,但在半导体芯 片、太阳能光伏、光纤通信、航空航 天、精密光学和特种玻璃等高新技术产 业中,却扮演着举足轻重的角色,堪称 这些领域的"灵魂材料"。 高纯石英砂:为何如此独特? 高纯石英砂的魅力,源自其卓越的物 理化学性质。其独特的晶体结构、物 理和化学性质,赋予了它耐高温、耐 腐蚀、热膨胀系数小、抗热震性能 好、高度绝缘等"超能力"。更为难 得的是,它还具备压电效应、谐振效 应以及独特的光学特性,这些特性使 得高纯石英砂成为半导体等工业对载 具等加工器件材料中碱金属和重金属 含量要求极为苛刻的理想之选,堪称 天然水晶,因其晶体结构完整、纯度高 而备受青睐。然而，天然水晶的生长条 件苛刻,储量有限,导致原料稀缺,成 本高昂。 对于高纯石英砂的定义,业界尚无统一标 准。但我们可以从多个角度窥见其真容。 国际公认的高纯石英砂要求杂质元素的含 号小干20ppm,其中碱金属更是被严格限 科技界的"全能选手" 制在1ppm以下,而在更高级别的标准 中,则对Fe、Mn、Cr、Ni等1 ...
