X Link®:瞬间完成交联控制

在太阳能模块中,乙烯醋酸乙烯酯(EVA)和聚烯烃封装可为敏感的太阳能电池提供保护。因此,乙烯醋酸乙烯酯(EVA)或聚烯烃分子间的交联度对模块的长期稳定性和性能有着决定性影响。在层压过程中,可通过对聚合物进行热固处理实现交联。X链接系统可在层叠后立即对乙烯醋酸乙烯酯(EVA)或聚烯烃进行评估,具有快速性、自动化、非破坏性和准确性等特点。该系统可集成于任何太阳能模块生产线,100%的覆盖整个制程和质量控制过程。

联机版本

在联机应用中,测量头可集成于层压机的冷却压机上,或集成于生产线中。系统中的多测量头可测定中心点至边缘之间的均匀性。以此促进X链接闭合回路的反馈过程控制,保证质量。

离线版本

离 线版本适用于实验室、手动的手持式生产线、研发实验室和试验性生产线,可以配备或未配备框架的条件下测试全尺寸生产模块。研发实验室甚至可以在不使用玻璃 或背板的情况下,检测乙烯醋酸乙烯酯(EVA)或聚烯烃板。可执行高分辨率的交联度空间映射。此外,手动离线版本可实现对层压模块、脱产模块和现场模块的 多点测量。对于模块制造商、投资商、认证机构和顾问而言,该装置是一款非常有效的质量控制工具。 X链接离线系统不仅适用于工程师和操作人员,用户在使用该系统时,可以方便的定位测量头下方的模块。此外,该设备还支持激光束定位。设备配备有触摸屏,可 通过用户友好型软件控制整个测量过程。

X Link® SAM: semi automated mapping system

PV module lamination control: Mapping of curing state of encapsulant across the whole moduleX Link® SAM is a semi-automated X Link mapping system which  creates maps of the curing state of full-size modules. After loading a module into the device, the tool measures the degree of cross-linking at predefined positions on the module with a typical measurement time of less than one minute per point. The whole measurement procedure is non-destructive and does not affect the functionality of the tested modules. Presentation of the measured data as color maps give immediate information on the uniformity of the curing state of the encapsulant across the whole module.

The X Link® SAM has been developed with focus on regular spot tests in production lines and delivery control. Used in a production line, it gives fast feed-back on homogeneity in the lamination process, allowing quick reaction on production issues. In delivery control it allows to check the quality of the encapsulation, spotting quality issues at a glance.

优势

在使用X链接直接反馈时,可以快速优化层压工艺,通过调节加热区和层压的持续时间,获取更好的交联质量。完美的层压工艺是生产高质量模块的关键。

X Link® in mass production

X Link® offers a lot of benefits for mass production of PV modules. Hanwha Q CELLS GmbH (Germany) published recently the results of their X Link® evaluation. Their tests have shown that the tool provides extremely accurate measurements, faster and more exact process control, quality control, recipe evaluation as well as laminator characterization. All this enables an early failure detection and saves costs! Find more in our summary of Hanwha’s technical paper  …more>

Calibration

High accuracy of X Link® systems is indispensable for process control and quality management in solar module production. It is recommended to calibrate X Link® after its delivery or moving as well as once a year to fulfill the requirements of quality auditors. To guarantee X Link's high precision, LayTec offers X Cal - a set of high precision equipment for on-site calibration of X Link® systems.

背景

雷 泰和弗劳恩霍夫USA联手研发了这一新方法,用于测量密封剂的交联度。该方法以与交联水平相关的物理性质测量为基础。通过北板执行高精确度测量,因此可确 定密封剂的交联度未受到破坏。测量过程仅需几秒钟,不会影响被测模块的性能,精确度可达±1.5%。该方法已成功应用于乙烯醋酸乙烯酯(EVA)和聚烯 烃。通过对X链接的进一步研究,可适用于其他新型的密封剂材料。
