他们的环氧胶粘剂貌似已经通过了GL认证，还给了我们很多样品，还有低温快速胶粘剂，现在还堆在库房里，都没试过，不知道好不好啊。
不是媚外，是不敢啊。

我测过，拉剪不错，Tg比HEXION低不少。应该国内有少量在用了。

这是2008年发生的事情：

Suzlon Blade Recall: Retrofit Program to Address Cracking

Suzlon Energy Ltd. (Pune, India), the world’s fifth leading and India’s largest wind turbine manufacturer, has announced a retrofit program to resolve blade cracking issues discovered during the operations of some of its S88 turbines in the United States.

The retrofit program involves the structural strengthening of 1,251 composite blades (417 sets) on S88 (2.1 MW) turbines, of which 930 blades are already installed, while the remaining blades are in transit or inventory.

“We have a close working relationship with our customers, and this program is a proactive measure to safeguard the interest of all our stakeholders,” says Andre Horbach, CEO of the Suzlon Group, in a company press release. “The retrofit program is designed to minimize impact for our customers and Suzlon.”

Horbach added that the company, with its integrated global value chain and in-house blade design and manufacturing capabilities, is equipped to resolve the issue within a short time frame and in a cost-efficient manner: “We are in close contact with all our customers and are keeping them fully informed of the progress. We expect no impact on the order and execution pipeline.”

The six-month retrofit program will be carried out by maintaining a rolling stock of temporary replacement blades to minimize the downtime for operational turbines. The program will use Suzlon’s global technical capabilities and its blade manufacturing and service facility in Pipestone, Minn., for U.S. blades. The cost of the retrofit program is estimated to be $25 million (USD).

历时六个月的修复，直接成本：2千5百万美元。

每一片的直接修复费用就为2万美元。

关键是大家要对结构胶性能要求进行全面剖析，针对某一指标进行评价，不科学。HUNTSAMAN的聚氨酯的Tg只有50度，也照样用于叶片结构粘接。作为技术工作者，我觉得，我们应集体行动，大家都提出合理的技术要求，让有条件的朋友进行测试，大家一起跟随国内风电的发展，一起成熟。

不敢，不敢，

可以考虑把油污状物采集送到实验室作红外光谱分析看看，如果反应不完全就可以看到双酚A或者F，还有胺类固化剂(或者其他类固化剂的基团) ,即使与固化后也可以看出特征峰的。如果出现其他化学基团的特征峰，用产商标准样对比特征峰。

老吴应该没学过有机分子结构波普分析吧，这可是我的老本行[s:1]

wumingsheng

啥子分子结构波谱分析？  俺没印象阿，好像仪器分析里面没记得有这个名称。

是红外光谱分析，分析基团特征峰。

wumingsheng

检测某种分子基团的存在，不需要去搞什么分子结构分子分子。 [s:2]

如果需要可以把分析流程搞上来，

国际上做环氧产品的，都在搞多元胺固化体系的这个问题。抑制极性基团与空气中的水汽和 carbon dioxide 之间的反应

大哥，已经说了，不是去搞大分子结构分析。

用不到那老什子。　 [s:2]
