塑料焊接原理

塑膠熔接常見的熔接方式（二）

一、高周波熔接
主要原理是由電子管自激振蕩器産生高頻電場，使塑料內部極性分子高頻運動沖撞産生內熱，經壓合後達到熔接的目的。
适用：分子具有极性的塑料薄膜的热合，各种聚氯乙烯（PVC）为主的塑胶，其中産品有鞋类、商标、贴纸、雨衣、雨帆、雨伞、皮包、手提袋、海滩袋、文具、名牌、吹气玩具、水床、汽、机车坐垫、遮阳板、车门板、特殊硬壳真空包装。

二、热熔熔接
直接通過加熱板對受熱件進行高溫加熱，溶解，達到鉚合或金屬件埋植的目的。
适用：用于螺丝埋植及热铆压，如开关、手机、各类电子産品。

三、塑封口機
主要用于吸塑泡壳与纸卡的热合包装，利用脉冲发热原理36V电压使电木模具发热，根据工件大小（热合面积）选择不同电流输出及通电时间，然后在冷却加压情况下完成热合包装。包装産品透明美观，包装速度快。
適用：包裝精美玩具、文具、日用品、化妝品、工業品及五金制品、小型工具等，封成美觀透明外套，盡量令被包裝之物品表露各種優點，一目了然。

塑膠熔接常見的熔接方式（一）

‘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.
