塑料焊接原理

塑料中含有氟素，爲何“超聲波焊接”無法密合

若塑料材质内含氟素原料，焊接方式为先挤压熔接柱（单点），然后超声波溶化熔接柱使两零件接合（面接合处有超声波线），産品熔点为263度，此温度应是超声波熔接可作业的范围，但熔接后却总是无法达到密合的地步。

解析：
1.若材質是超聲波熔接領域的範圍，但無法達到熔合的效果，應可從幾點分析：
a)熔接加工條件（如緩沖、熔接時間、硬化是否爲最佳設定）；
b)産品定位（以阶梯公母套定位为佳）；
c)超声波导熔线是否符合産品功能需求（如焊接质量、水密要求、气密要求等）；
d)超声波机器的输出能量是否适当。

2.任何産品使用超声波熔接，均建议提早发振，即上模接触産品前约3~5mm时，先将超声波发振，并调整下降缓冲，让第二段行程速度降低，这即为産品熔接的预热原理。

“超聲波”焊接塑料不均勻的原因

超聲波焊接與塑料特性

‘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.
