他們的環氧膠粘劑貌似已經通過了GL認證，還給了我們很多樣品，還有低溫快速膠粘劑，現在還堆在庫房里，都沒試過，不知道好不好啊。
不是媚外，是不敢啊。

我測過，拉剪不錯，Tg比HEXION低不少。應該國內有少量在用了。

好久沒來了，各位行業朋友以后請多指教

這是2008年發生的事情：

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).

歷時六個月的修復，直接成本：2千5百萬美元。

每一片的直接修復費用就為2萬美元。

關鍵是大家要對結構膠性能要求進行全面剖析，針對某一指標進行評價，不科學。HUNTSAMAN的聚氨酯的Tg只有50度，也照樣用于葉片結構粘接。作為技術工作者，我覺得，我們應集體行動，大家都提出合理的技術要求，讓有條件的朋友進行測試，大家一起跟隨國內風電的發展，一起成熟。

不敢，不敢，

可以考慮把油污狀物采集送到實驗室作紅外光譜分析看看，如果反應不完全就可以看到雙酚A或者F，還有胺類固化劑(或者其他類固化劑的基團) ,即使與固化后也可以看出特征峰的。如果出現其他化學基團的特征峰，用產商標準樣對比特征峰。

老吳應該沒學過有機分子結構波普分析吧，這可是我的老本行[s:1]

wumingsheng

啥子分子結構波譜分析？  俺沒印象阿，好像儀器分析里面沒記得有這個名稱。

是紅外光譜分析，分析基團特征峰。

wumingsheng

檢測某種分子基團的存在，不需要去搞什么分子結構分子分子。 [s:2]

如果需要可以把分析流程搞上來，

國際上做環氧產品的，都在搞多元胺固化體系的這個問題。抑制極性基團與空氣中的水汽和 carbon dioxide 之間的反應

大哥，已經說了，不是去搞大分子結構分析。

用不到那老什子。　 [s:2]
