近日，有网友发文称，用湿巾擦拭星宇橙配色的iPhone 17 Pro Max后，手机镜头组边缘和摄像头凸起处的表面着色层脱落，露出银色金属底色，但背板主体 部分仍保留原本的星宇橙颜色。湿巾清洁却致手机"毁容"，不少网友质疑高昂的电子产品漆面竟如此"脆弱"。 手机表面着色层掉色，湿巾该不该"背锅"？如何科学清洁电子产品？12月9日，科技日报记者采访了北京化工大学材料科学与工程学院副教授赵旭辉。 不全是湿巾的"锅" 针对此次湿巾擦拭iPhone 17 Pro系列星宇橙机身导致掉色的原因分析，网友给出了两种不同的主流观点。一种观点认为是使用了含有漂白、强氧化等功能的 湿巾导致的，属于不当清洁。苹果中国大陆客户服务热线工作人员曾向媒体透露，普通湿巾擦拭不会影响机身颜色，但如果使用含高浓度酒精、丙酮或其他 含腐蚀性液体的湿巾则有可能掉色。另一种则认为主要与iPhone 17 Pro系列产品的生产工艺缺陷有关，湿巾并非主要原因。 "此前有用户表示，iPhone 17 Pro星宇橙机身在紫外线照射后也出现了变色。目前苹果公司官方并未披露具体原因，但从多个掉色案例可以认为，掉色不全 是湿巾的锅，最多算是诱因，根本原因还得归结 ...

Core Viewpoint - Apple is reportedly recalling iPhone 17 Pro and iPhone 17 Pro Max devices due to a color fading issue, which is believed to be a limited manufacturing defect rather than a widespread problem [1][9]. Group 1: Issue Overview - Users have reported color changes in their iPhone 17 Pro and Pro Max, particularly in the "Starry Orange" color, leading to significant attention on social media [1]. - The fading issue has been observed mainly at the edges and around the camera bump, while the back panel with the Apple logo remains largely unchanged [1]. - Some users have also noted similar fading in the deep blue version of the iPhone 17 Pro, although the color difference is less pronounced [3]. Group 2: Technical Analysis - Apple has advised against using bleach or hydrogen peroxide for cleaning the iPhone 17 Pro, suggesting that exposure to such substances or prolonged UV light may contribute to the discoloration [7]. - Analysts suggest that the issue may stem from the aluminum alloy used in the iPhone 17 Pro, which is less corrosion-resistant than the titanium alloy used in previous models, making it more susceptible to oxidation [7]. - The anodization process, which is intended to protect the aluminum, may not have been properly sealed during production, allowing the aluminum to oxidize and change color [8]. Group 3: Company Response - As of now, Apple has not officially responded to the reports of color fading, but users have indicated that Apple is providing replacement services for affected devices [9].
