如何控制纏繞膜生産的溫度？缠绕膜在生产过程中会受到各种因素的影响，这些因素会对缠绕膜质量多多少少会存在影响，在这里小编来和大家探讨一下关于控制缠绕膜生产的温度的问题，这也是关系到生产质量好坏的因素，下面我们就一起来看一下吧。

拉伸纏繞膜生産溫度要控制的恰當，才能保證流延生産線的穩定，生産的拉伸纏繞膜産品更加優質。

拉伸纏繞膜爲了保證不斷膜，要讓張力穩定，就控制在10kg以內，避免伸長率等性能降低導致的斷膜。生産中冷卻輥溫度升高，屈服強度提高，但是就會導致其他的功能降低，流延加工膜的溫度以20℃～30℃爲佳。流延線的張力影響拉伸膜的平整度及收卷松緊度，所以要注意這一點。流延法生産熔體溫度範圍一般控制在250℃～280℃，避免流動速度快。在進行冷卻的時候溫度控制在20℃～30℃，收卷張力要低，讓粘性劑遷出PVC拉伸纏繞膜生産溫度如何控制同時減少拉伸膜內應力。

上面就是我們的小編給大家整理的關于控制纏繞膜生産的溫度的問題，相信大家在生産的時候注意各方面的因素可以生産出質量更好的纏繞膜。

"Don't bother," said the Clockwork man, as Arthur stirred slightly, "I'm not going that way. I shall go back the way I came." "This is dreadful," he said. "The man who died in the Corner House changed four hundred sovereigns into notes. Part of them he put into a letter to send to a certain person who appears to have been nameless. We know that he was going to send that money to his brother." Hetty permitted herself the luxury of a smile at Gilbert's expense. 3. The saving from condensation, to which steam is exposed, avoidance of heat, and the consequent contraction and expansion of long conducting pipes. Before entering on our task, one more difficulty remains to be noticed. Plato, although the greatest master of prose composition that ever lived, and for his time a remarkably voluminous author, cherished a strong dislike for books, and even affected to regret that the art of writing had ever been invented. A man, he said, might amuse himself by putting down his ideas on paper, and might even find written178 memoranda useful for private reference, but the only instruction worth speaking of was conveyed by oral communication, which made it possible for objections unforeseen by the teacher to be freely urged and answered.117 Such had been the method of Socrates, and such was doubtless the practice of Plato himself whenever it was possible for him to set forth his philosophy by word of mouth. It has been supposed, for this reason, that the great writer did not take his own books in earnest, and wished them to be regarded as no more than the elegant recreations of a leisure hour, while his deeper and more serious thoughts were reserved for lectures and conversations, of which, beyond a few allusions in Aristotle, every record has perished. That such, however, was not the case, may be easily shown. In the first place it is evident, from the extreme pains taken by Plato to throw his philosophical expositions into conversational form, that he did not despair of providing a literary substitute for spoken dialogue. Secondly, it is a strong confirmation of this theory that Aristotle, a personal friend and pupil of Plato during many years, should so frequently refer to the Dialogues as authoritative evidences of his master’s opinions on the most important topics. And, lastly, if it can be shown that the documents in question do actually embody a comprehensive and connected view of life and of the world, we shall feel satisfied that the oral teaching of Plato, had it been preserved, would not modify in any material degree the impression conveyed by his written compositions. Poor old Grove is dead. He got so that he couldn't chew and they You know that I've always had a very special feeling towards you; not strong. Take care and don't catch cold. These fall rains A bulbul, flying out of a temple where it had been picking up the offered rice, perched on a pomegranate tree and began to sing, at first a little timid chirp, and then a ripple of song, soon drowned by the shrieks of parrots, which came down on the tree and drove out the little red-breasted chorister. “That doesn’t check up,” he said. “The confederate—Mimi—knew the imitations! She wouldn’t throw them at all. If she knew the real ones were hidden in that life belt she’d have flung that. But we know that the imitations went overside and were in the gum—as Sandy cleverly discovered. So—that makes it all muddled up again!” "Good boy," said Si, patting him on the shoul der. "You're a soldier already." The Deacon Reconnoitered the Situation 62 "I'm sorry, General, that you felt that Click place so bad that you were compelled to take personal action. I have known for some time that something ought to be done, but I've been trying to collect evidence that would hold Glick on a criminal charge, so that I could turn him over to the civil authorities." Evidently he had pleased the multitude, for there was now a thick crowd in the central space, and already dancing had begun. Farm-hands in clean smocks, with bright-coloured handkerchiefs round their necks, gambolled uncouthly with farm-girls in spotted and striped muslins. Young farmers' wives, stiff with the sedateness of their bridehead, were drawn into reluctant capers. Despairing virgins renewed their hope, and tried wives their liveliness in unaccustomed arms. Even the elders danced, stumping together on the outskirts of the whirl as long as their breath allowed them. That night he lay awake long hours in the smell of apples. He pondered many things. Those past months had been sweet in their revived tenderness, their simple freedom. But Boarzell had reasserted itself—Naomi was now quite well again—she must no longer shirk her duties. She must have more children. HoME 全免费午夜一级毛片1川1川ENTER NUMBET 003www.ge5.com.cn
