2026年,湖南省长沙理工大学电网防灾减灾重点实验室在《Coatings(ISSN2079-6412)》(SCI期刊，MDPI工程材料类主流期刊)发表文献《SynergisticAgingResistanceandAutonomousSelf-HealinginTrimethylolpropane Triglycidyl Ether-Based Anti-Icing Coatings》,文献中使用LUYOR-3500L用于自修复耐老化防冰涂层紫外老化测试.LUYOR-3500L拥有精准稳定紫外输出：标配 90 W 365 nm 专用紫外灯管，辐照强度均匀，样品台距离标准化 20 cm，辐照能量恒定，防冰涂层紫外老化实验数据误差小，适合电力功能涂层标准化耐候评测,LUYOR-3500L还有长时连续运行能力：支持长时间不间断连续老化，无需中途停机维护，匹配长效防冰涂层加速耐候测试需求,此外,LUYOR-3500L不仅适用于本研究 PDMS 基防冰涂层，还可用于生物分子交联,大肠杆菌中RecA突变筛选,核酸的膜交联等.
长沙理工大学联合国网湖南电力搭建电网防灾减灾重点实验室，是国内以输变电设备防灾减灾为研究方向的科研平台。 实验室聚焦电网防冰、防山火、防雷及储能安全等技术领域，研制出特高压导线不停电地线融冰装置、新型氟基灭火技术和环形氧化锌避雷器等成果，应用于26省市电网及19个特高压抗冰工程。实验室建成我国电网防灾产业园，其配电网真型试验场是大型10kV真型试验场。
本实验采用LUYOR-3500L作为核心加速老化测试设备，用于模拟户外太阳光中 365 nm 紫外波段持续辐照环境，对 PAT 系列防冰涂层开展长时紫外耐候加速老化测试，LUYOR-3500L可以定量对比老化前后涂层分子结构、润湿性、结冰延迟时间、冰附着强度等关键防冰指标衰减幅度，验证涂层抗紫外老化长效防护能力,所有涂层经LUYOR-3500L紫外交联仪长时间辐照后，防冰性能保留率均高于70%，证实耐紫外老化与自修复、低冰粘附协同平衡.
该研究证实，LUYOR-3500L紫外交联仪可用于做自修复耐老化防冰涂层紫外老化测试。LUYOR-3500L紫外交联仪在国内外高校和科研院所得到广泛好评，欢迎私信或留言联系上海路阳了解详情！

LUYOR-3500L设备原文描述
UV aging was conducted in a LUYOR UCL-3500L UV cross-linking chamber (Shanghai, China). Coatings were positioned 20 cm directly beneath a 90-watt UV lamp (wavelength: 365 nm) for 168 h of continuous exposure.
紫外老化后涂层表观与性能原文
Following 168 h of UV irradiation, the coating exhibited slight color deepening without observable blistering or chalking. After UV aging, the retention rates of the freezing delay times for PAT₁, PAT₂, and PAT₃ are 70.2%, 77.6%, and 71.6%, respectively, while the corresponding retention rates of ice adhesion strength are 69.7%, 83.4%, and 84.1%, respectively. The coating’s UV resistance is primarily attributable to the absence of free radicals in PDMS and copolymer polymer chains, which prevent photochemical degradation. Additionally, UV attenuation is enhanced through π→π* electron transitions in the aromatic ring system, where increased benzene ring density improves radiation absorption.
紫外老化后红外结构分析原文
FTIR analysis has been conducted on the PAT coating that underwent a 168 h UV aging test. The results of this analysis are then compared with those of the original sample. UV irradiation accelerated the oxidation/rearrangement of organic components in the cured network, and the magnitude of structural changes is proportional to the APD ratio.
