湖南省長沙理工大學使用LUYOR-3500L紫外交聯儀對電力輸變電、風電葉片長效戶外防冰涂層紫外加速老化的性能評測,模擬戶外太陽光紫外輻照環境,定量表征防冰涂層紫外耐候、長效防冰性能衰減規律。紫外交聯儀LUYOR-3500L擁有精準穩定紫外輸出:標配 90 W 365 nm 專用紫外線燈管,輻照強度均勻,樣品臺距離標準化20cm,輻照能量恒定,防冰涂層紫外老化實驗數據誤差小,適合電力功能涂層標準化耐候評測。此外,紫外交聯儀LUYOR-3500L還有長時連續運行能力:支持長時間不間斷連續老化,無需中途停機維護,匹配長效防冰涂層加速耐候測試需求。紫外交聯儀LUYOR-3500L不僅適用于本研究 PDMS 基防冰涂層,還可用于生物分子交聯、大腸桿菌中RecA突變篩選、核酸分子膜交聯等。
長沙理工大學聯合國網湖南電力搭建電網防災減災重點實驗室,是國內以輸變電設備防災減災為研究方向的科研平臺。實驗室聚焦電網防冰、防山火、防雷及儲能安全等技術領域,研制出特高壓導線不停電地線融冰裝置、新型氟基滅火技術和環形氧化鋅避雷器等成果,應用于26省市電網及19個特高壓抗冰工程。實驗室建成我國電網防災產業園,其配電網真型試驗場是大型10kV真型試驗場。
本實驗采用紫外交聯儀LUYOR-3500L作為核心加速老化測試設備,用于模擬戶外太陽光中 365 nm 紫外波段持續輻照環境,對PAT系列防冰涂層開展長時紫外耐候加速老化測試,紫外交聯儀LUYOR-3500L可以定量對比老化前后涂層分子結構、潤濕性、結冰延遲時間、冰附著強度等關鍵防冰指標衰減幅度,驗證涂層抗紫外老化長效防護能力,所有涂層經LUYOR-3500L紫外交聯儀長時間輻照后,防冰性能保留率均高于70%,證實耐紫外老化與自修復、低冰粘附協同平衡。
該研究證實,LUYOR-3500L紫外交聯儀可用于涂層紫外老化測試。目前,LUYOR-3500L紫外交聯儀已經在國內外高校和科研院所投入使用并得到廣泛好評,歡迎私信或留言聯系上海路陽了解詳情!
原文段落
LUYOR-3500L紫外交聯儀原文描述
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.
紫外老化后涂層表觀與性能原文
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 PAT?, PAT?, and PAT? 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.
紫外老化后紅外結構分析原文
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.
