分析臭氧老化試驗機的動、靜態試驗

来源：林频环境试验解決方案作者：林頻儀器发布日期：2021-08-19 13:33

　　臭氧老化試驗機分爲兩種風格，動態和靜態拉伸試驗，主要是因爲內部夾具的不同，其中動態的可以滿足靜態試驗，但是靜態不能滿足動態。所以購買測試設備前，須考慮到産品測試的動態與靜態。

分析臭氧老化試驗機的動、靜態試驗

　　臭氧老化试验可以提高产品的使用价值和适用性。臭氧老化試驗機作为环境模拟加速老化的气体腐蚀试验，根据不同产品的使用情况而定义使用哪种试验状态。

　　臭氧老化試驗機的动态拉伸试验是将样品的两端夹在标准规定的夹具上，使夹具可以自动伸缩，使样品进行拉伸复位，拉伸频率为0.5±0.025Hz，拉伸速率为0-极限拉伸值，在规定的臭氧浓度下，夹具上的样品循环拉伸复位，并与样品架一起旋转进行试验。在规定时间后，检查样品是否开裂。

　　靜態拉伸試驗是將樣品伸長到一定的伸長率，一般爲20%。夾具安裝在旋轉的樣品架上。樣品架轉速在(20-25)毫米/立方米之間，溫度爲(40±2)℃，相對濕度不超過65%。樣品在規定時間後開裂。

　　通过以上分析。小编希望客户在了解完臭氧老化試驗機的动、静态试验，在试验时合理的考虑样品适应性。我司专业生产各种试验设备，有需要的客户可以联系我司。

Lawrence laughed and departed with the assurance that Isidore should know soon enough. He spent the rest of the morning at the club, and after luncheon took his way gaily in the direction of Lytton Avenue. We could not keep to the main road all the time, for it was forbidden by proclamation to go farther than nine miles and a half from the town, and we should have been stopped without fail. And disadvantaged aye begins the strife. "Who told you he was?" she asked. Alberoni, though defeated at sea, was more successful in Sicily, and he continued his cabals against England in nearly every Court of Europe with only the more assiduity. He was zealously at work in France, England itself, Holland, Piedmont, and Sweden. By his ambassador at the Hague he endeavoured to keep the Dutch out of the Quadruple Alliance by exciting their commercial jealousy; but he was ably opposed by our minister there, the Earl of Cadogan. In Piedmont he endeavoured to deter Victor Amadeus from entering into this alliance by assuring him that he was only endeavouring to secure Sicily to keep it out of the hands of the Austrians, and reserve it for him; while, on the other hand, he threatened him with thirty thousand bayonets if he dared to accede to the Quadruple Treaty. The Allies, however, threatened still greater dangers, and the Duke at last consented to accept Sardinia in lieu of Sicily, and that island remains attached to the kingdom of Italy to the present time. AFTER CULLODEN: REBEL HUNTING. Grenville, being on the look-out for new taxes, had paid particular attention to the rapid growth of the American colonies, and was inspired with the design of drawing a revenue from them. The scheme had been suggested to Sir Robert Walpole, when his Excise Bill failed, by Sir William Keith, who had been governor of Pennsylvania; but Sir Robert had a far deeper insight into human nature than the shallow and obstinate Grenville. He replied, "I have already Old England set against me, and do you think I will have New England set against me too?" "Simeon Wheelwright." along at the head of Co. Q, though I have been Acting Major "No," answered the Captain; "help has been sent for for them, and there it comes." "There is nothing for me to do," she said, and her eye closed. "No. I wait for you, but only to tell you this: there is nothing I can do." "Stand clear!—who wants your tricks? I'm going to show him wot a man's worth—a man wot's had his beard longer than this puppy's bin in the warld." She pulled herself together with an effort. Calverley was now forced to assume a courage which he did not feel; and looking sternly around, he asked, in as firm a voice as he could command, why he was thus surrounded? or whether they intended to make him a prisoner?
