造成複合卷膜卷曲的原因有哪些

2020/09/20 分類:材料新聞 1736 0

當下的複合卷膜已经运用到了各个行业内，而且需求还在不断的扩大，因此在选择购买複合卷膜的时候要注意，一定要注意複合卷膜是否有卷曲。

一般複合卷膜在进行复合的过程时，会受到多方面的影响如(机器、温度等)，从而导致複合卷膜出现卷曲的问题。以下是複合卷膜卷曲出现的规律：

首先是內層材料：當它的收縮率越大，而在此同時，外層的材料的挺度也越差的情況下，這個時候出現複合膜的卷曲就大大增加了這個幾率。

其次是縱向卷曲程度：當它大于橫向的卷曲程度並且開口長度越長的話，那麽它的卷曲也是越明顯，這是由于收到張力的影響。

在有是複合成品：幹複産品會比擠複産品少出現翹曲的現象，這是因爲前者在生産時不用設定高溫。

最后是其它方面：常见的有复合张力未控制好、收卷触压未控制好、干燥温度未控制好等问题也是引起複合卷膜卷曲的原因

以上是对于“造成複合卷膜卷曲的原因有哪些”的介绍，希望对您有所帮助。飞富润包装彩印是一家专业生产複合卷膜的厂家，可根据客户需求进行定制生产。

"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 0010www.aaa73.com.cn
