口罩生产中需应用到的靈科超聲波焊接工艺

返回列表 來源：发布日期： 2022.04.13

口罩已經成爲我們生活中必不可少的消耗品。口罩的核心材料主要是熔噴布。如何制作口罩？實際上，口罩的制造工藝是會應用到超聲波焊接工藝的。超聲波焊接使用高頻振動波傳遞到兩個待焊接的物體表面。在壓力下，兩個物體表面相互摩擦，形成分子層之間的融合。

當超聲波作用于熱塑性塑料的接觸表面時，口罩上到處可以看到一些凹痕，如封邊、耳帶和呼氣閥，這些凹痕由超聲波焊接而成，它每秒將産生數萬次高頻振動。這種具有一定振幅的高頻振動將通過上部焊件將超聲波能量傳輸到焊接區域。由于兩個焊接區域之間的界面聲電阻較大，會産生局部高溫。

如上圖所示，在口罩的生産過程中，我們可以直觀地了解全塑料鼻梁條的焊接、折疊後的焊接、呼吸閥焊接、多層滾焊和耳帶焊接，這些都是可以通過超聲波焊接工藝完成的。

‘Oh, yes, you could. Now do just as I tell you, Alice. When you’ve eaten, we’ll talk again.’ "Not a sign of a sign! And yet I'll swear it! Do you know where she's gone?" "Go along with your doctor," said Maitrank now, in great good humour. "If you will have the goodness to call a cab I will get back to my hotel." "I am...." “Bad news?” Larry asked, climbing to the turf. Larry braced himself against the slap of the wheels into the surface water. That might offer just enough resistance to nose them in. However, it ended, as soon as Mr. Everdail had sailed on the yacht to join his wife at their lakeside camp in Maine, uncanny light, odd noises and other strange things had become evident again, as an excited local correspondent had notified the paper. Reporters, searching, and watching, had found nothing so far but the public would be informed as soon as they discovered the secret. He believed that he had no ties now, that friendships, the love of woman, and the kiss of children all had missed him, and that his, thenceforth, must be but vain regret. So far as he knew, Felipa had gone away without ever having received his letter. The man he had intrusted it to had been killed in the Aravaypa Ca?on: that he was certain of; and it never entered his head that his papers might have fallen into other hands, and the note have finally been delivered to her. She was leading the sort of life that would most quickly put him entirely out of her mind. He was taking the Washington papers, and he knew. She had gone away, not even sure that he had given her a thought since the night in the Sierra Blanca when Black River had roared through the stillness, and they had been alone in all the wild world. What a weird, mysterious, unearthly scene it had been, quite outside the probabilities of anything he had imagined or contemplated for a single minute. He had never regretted it, though. He believed in impulses, particularly his own. Yet she not only loved Cairness as much as ever, but more. Her church had the strong hold of superstition upon her, but she might have thrown it off, grown reckless of enforced conventions, and have gone to him, had not faithfulness and gratitude held her yet more powerfully. "Yes, that is she; glad to see you back, Missy," said the General, patting the cow on the back. "Take her back and give her a good feed, if you can find it, for probably she's pretty hungry." Have you never heard of AMP burning them, you silly damn fool? Her young face bowed to his neck, and suddenly his lips crept round and lay against the coolness of her cheek. She did not move, and he still walked on, the grass splashing under his feet, the rabbits scampering round him, showing their little cotton-tails in the dark.
