如何對複合膜進行檢測呢

2020/09/19 分類:行業資訊 1314 0

在衆多材料加工成包裝袋之後，在暴露在環境中時，會收到各種各樣的影響，從而導致包裝袋的複合層收到損害，因此我們需要對複合膜進行檢測，最終檢測出適合我們的材料。

那么要如何對複合膜進行檢測呢?具体如下：

第一點試樣准備：複合膜等材料的試樣尺寸爲寬(15.0+0.1)mm，長200mm。

第二點試樣制備：將複合膜樣品寬度方向的兩端除去50mm，沿樣品寬度方向均勻采取縱、橫試樣各5條。複合方向爲縱向。

第三點試驗環境：試樣應在溫度(23+1)℃、相對濕度45%～55%的環境中放置4h以上，然後在上述環境中進行試驗。

第四點試驗速度：(300+50)mm/min。

以上是對于“如何對複合膜進行檢測”的介紹，希望對您有所幫助，飛富潤是一家專業生産各類包裝袋的廠家，若您有需要可以直接聯系在線客服進，獲取相關資料。

"But you don't get all the whales you see, by a long shot. Many a whale gets away before you can fasten to him, and many another whale, after you have laid on and fastened, will escape you. He sinks, and tears the iron loose; he runs away to windward ten or twenty miles an hour, and you must cut the line to save your lives; he smashes the boat, and perhaps kills some of his assailants; he dies below the surface, and when he dies there he stays below, and you lose him; and sometimes he shows[Pg 66] such an amount of toughness that he seems to bear a charmed life. We fight him with harpoon and lance, and in these later days they have an invention called the bomb-lance or whaling-gun. A bomb-shell is thrown into him with a gun like a large musket, and it explodes down among his vitals. There's another gun that is fastened to the shaft of a harpoon, and goes off when the whale tightens the line; and there's another that throws a lance half-way through him. Well, there are whales that can stand all these things and live. The reply came slowly. "No; her husband is quite another man; this man's wife has been dead for years. No, Charlotte Oliver lives in--hark!" "Since the hour of her marriage she has never gone into her chamber without locking the door; she has never come out of it unarmed." The only purpose of my publication was to convince everybody of this, and thereby prevent the repetition of such a scandalous scene. An interpreter translated to the accused the questions put by the judge, who understood the replies, though he was not allowed to speak excepting in English. Dick, examining with the thoroughness of an expert, with Jeff’s and his chum’s life perhaps depending on his care, stated that he saw no damage to the waterproofed coverings of the water supports. Declaring that they would stand by and watch the airplane, Sandy and Dick watched Larry and Jeff get settled, Dick spun the propeller to pump gas into the still heated cylinders, Jeff gave the “switch-on—contact!” call, Dick, pulling down on the “prop,” sprang aside to avoid its flailing blades, and the amphibian’s engine took up its roar. He transmitted the suggestion. Almost as his hand touched the cable and twitched at it, his other hand, as he lay with his weight on his chin, face and chest, contacted something else—a large, roundish object, feeling like a spare landing wheel tire. It was short and to the point upon Cairness's part, and having finished he stood up. "I don't believe a word of hit," said the woman, who yet showed that she was touched by the allusion to the Baptist Church, as the Deacon had calculated, for most of the people of that section professed to be of that denomination. "What'll yo' gi' me for them chickens?" HoME 学生妹被老师 ENTER NUMBET 00102000sc.com.cn
