摘要以某化肥公司1200氨冷器殼體開裂泄漏的失效分析為例，通過對檢驗數據和結果及有關文獻資料的分析研究，探究了液氨介質壓力容器產生應力腐蝕裂紋的原因：設備中存在較高的焊接殘余應力；液氨介質具備應力腐蝕環境，即含水量0 . 2 % ，且有空氣（ o2或co2 ）污染（或摻入） ，使用溫度高於零下5 ；母材強度越高，應力腐蝕裂紋產生的傾向就越大。But its high leakage current and poor retention is the main obstacle to its application. improving the quality of ferroelectric thin films and avoiding the reaction and diffusion between f - s interfaces is one of the crucial keys to overcome this problem. that is to say that the preparation and properties of ferroelectric thin films is compatible with the semiconductor integrated circuit
但是其漏電流過大和保持力差成為制約其實用化的最大障礙，攻克這一難題的關鍵之一就在於鐵電薄膜質量的進一步提高，盡量減少或者避免f - s界面的互擴散，也就是說鐵電薄膜的制備工藝和各項鐵電性能必須與半導體集成工藝兼容。Alkaline zinc - manganese battery is widely used all over the world it has good performance of storage ， low cost ， stable discharge and convenience of carrying the sealing of the battery is a crucial factor to the performance of the battery due to the disadvantages of present sealants ， leakage of electrolyte often happens what ’ s more ， the sealing capability affects the performance of the battery the way to raise the sealing capability is to search for a good additive ， which can improve the sealing capability through adding according to chemical principles ， this article picks out ptfe and nylon66 as additive adding ptfe or nylon66 into the pitch can improve the sealing capability of the pitch at the same time ， the temperature ， the time ， the amount of addictive ， the way to drop temperature and the time of churning all should be considered by testing the constitutions ， softening point ， moving degree and length of needle of various pitch samples ， we can compare the properties of different sealants can be studied by using of x - ray, the constitutions of the pitch can be indicated which can help us to explain these changes this article includes ： testing the constitutions ， soften point ， moving viscosity and needle penetration of various pitches ； raising the sealing capability by adding ptfe nylon66 into the pitches ； testing the constitutions ， soften point ， moving viscosity and needle penetration of raised samples ； analyzing and discussing the basic principles of this method it is showed that soften point ， moving viscosity and needle penetration of pitches are increased by adding ptfe nylon66 and the discharge time ， initial voltage ， capacity of battery with pitch raised by nylon66 are good and get to the requirement of gb t7 1 1 2 in a11 the method proposed in this article is available in practical industry use
通過測定改進瀝青的軟化點、運動粘度和針入度等指標參數來比較不同的添加劑及不同的添加條件對瀝青封口性能的影響。本論文的主要研究結果為：系統測試了多種瀝青樣品的組成、軟化點、運動粘度、針入度；對市售瀝青分別添加聚四氟乙烯乳液、有機硅樹脂和尼龍66進行改進，制備了改進產品；對改進瀝青的組成、軟化點、運動粘度、針入度進行了測試和比較；使用改進瀝青組裝成電池並對電池進行恆電流放電測試、短路電流測試和電池漏氣、漏液性能的測試；對瀝青改進的原理進行了分析和討論。實驗結果表明：在瀝青中添加尼龍66和聚四氟乙烯乳液對瀝青的封口性能有明顯的提高；通過對工藝條件的不斷改進，目前的工藝條件已完全可以用於實際生產操作；以添加尼龍66改進的瀝青為封口劑組裝成的電池完全滿足堿錳電池生產的需要，且電池電容量、短路電流等指標均達到gb t7112標準要求；本文提出的改進方案，通過驗證是一種效果好、實用性強的方法。分享友人
