疊層無紡布材料焊接原理

無紡布的超聲波焊接應用

非織造布的“超聲波焊接”是一種極其快速和穩定的過程，易于重現且無需預熱即可立即使用。該技術可以同時進行壓花、層壓和切割。層壓材料提供令人愉悅的柔軟度，並滿足對舒適性和功能性的所有要求。

超聲波焊接即使對于具有熱塑性成分的無紡布，其原理也是可以通過超聲波激發和熔化材料的塑料成分，稱爲超聲波發生器的焊接工具將振動引入非織造布中。

在工业用途中，20 至 35 kHz 的超声波频率很常见，振幅（工具运动）为 10 ?m 至 50 ?m。非织造布通常以高幅速度在连续过程中加工。通过使用旋转刀具，加工速度可达800米/分钟。其具有表面结构的滚筒用作焊接、压花或切割砧。滚轮的轮廓集中能量并精确确定相应産品所需的焊接点。

无纺布的超聲波焊接特别适用于：

將不同的無紡布層層壓在一起
引入浮雕結構
被分離和被遺漏的邊緣區域

爲板材打孔

超聲波焊接腹板産品时，目标是保持材料和超声波发生器之间的距离恒定。因为只有这样才是好的，甚至可能的结果。“靈科超聲波”可爲客戶提供 珠海超声波、中山超聲波焊接机、江门超声波塑焊机、阳江超音波设备配件等。它通過位置分辨率非常高的步進電機控制進給單元或超聲波發生器的運動，從而確保超聲波工具中的熱感應變化是平衡的，並且超聲波發生器和輪廓滾輪之間的力始終保持不變。

“超聲波焊接”在无纺布行业的优势

‘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.
