塑料焊接原理

超聲波焊接與塑料特性

超聲波焊接與塑料特性

超声波熔接可应用到各种热塑性塑料制品上，不需要添加溶剂，粘接剂或其他的辅助品，不仅能提高生产率，降低成本，还能提高産品质量跟生产安全。

材料	塑料熔接特性	材料	塑料熔接特性
ABC 丙烯晴丁二烯苯藝烯共聚物	質輕，兼具轫性，剛性與耐化學品性，用途廣泛，此材質導熱性佳，特別適合超聲波熔接	General purposeps 一般聚苯乙烯	比重輕，對水及化學物之抗蝕性強，安定、絕緣性佳，特別適合于射出及壓出成形，常用于玩具、裝飾品、盂洗設備、磐子、透鏡、浮動輪等的制造。由于彈性系數高，適合超聲波熔接。
Acrylics壓克力	自重輕、硬度大、耐重擊、不受酸之作用，有高度光學明晰性，著色性良好，常用于汽車尾燈、儀表板、獎章、水龍頭把手等。超聲波熔接時，須注意衰明度問題。	Impact ps 耐重擊聚苯乙烯
Acetal 縮醛	抗張及耐壓強度高，耐磨性佳，最具強轫及強性，常用作接練、螺絲、軸承、滾筒、廚房用具等，因摩擦系數低，用超聲波熔接時需高振動幅度及較長的熔接時間。	20-30% glass Filled PS 玻織強化聚苯乙烯
Celluloeics 酯酸織維性物質	超聲波振動時材質易變化變色，接觸面不易吸收能量，熔接較困難。	Unmodified PP 聚丙烯	比重輕，熔點高，結晶度高，表面剛度和抗劃痕特性好，有良好絕緣性、抗吸濕性、抗酸堿腐蝕性、抗溶解性，抽絲後可制成繩綱等織品。對芳香烴（如苯）溶劑、氯化烴（四氯化碳）溶劑等沒有抵抗力。典型應用：汽車工業（主要使用含金屬添加劑的PP：擋泥板、通風管、風扇等），器械（洗碗機門襯墊、幹燥機通風管、洗衣機框架及機蓋、冰箱門襯墊等），日用消費品（草坪和園藝設備如剪草機和噴水器等）；制品有玩具、行李箱、音樂外殼、電氣絕緣物、食品包裝等。本材質因彈性系數低，易衰減聲波振動，較難熔接。
Noryl 聚苯醚	性極轫、電性佳、絕緣度高，常用爲電子零件等。因熔點高，所需熔接時間長，振幅高。	Filled pp 強化聚丙烯
Nylon 尼龍	材質強轫，耐磨損，摩擦系數極低，耐酸，常用作軸承、齒輪、管子、廚房用具、毛刷等。用超聲波溶接時，因熔點高，所需熔接時間長，熔接前先經烘幹會較易熔接。	PVC 聚氯乙烯	電性佳，耐弱化學品，低溫性佳，具難燃性，常用于各種合成皮軟管、料膜等，材質柔軟，易衰減聲波振動，熔接面易劣化。
P.C. 聚碳酸脂	耐熱，有絕佳透明性，拉伸及曲折強度高，常用于鏡片，如熱管、過濾器等。因熔接點高，所需熔接時間長。由于材質具吸濕性，熔接前應先烘幹。	Polyster 聚酸脂	熔接能量大
High Density PE 高密度聚乙烯	比重小，在低温及室温下富柔曲性，防水、防蚀、可制成各种颜色。价格低的産品，常用于皿磐、封装薄膜、软水管、奶瓶、软绳等。密度越高越适合于超声波熔接。	Polysulfone 聚砜	質硬、強度大、具轫性、長期受熱不影響其電性能，常用爲電視機零件護蓋、馬達零件等。因熔接點高，需較高之能量熔接。
Low Density PE 低密度聚乙烯		Polypheny lene Qxide(ppO) 聚氧化二甲苯	耐熱于耐濕性，耐化學品，不怕蒸汽，常用作端子、轉子、外殼、葉輪和管件等，熔點高，需較高之能量熔接。

塑料中含有氟素，爲何“超聲波焊接”無法密合

都知道超聲波能焊接塑料，但你清楚如何鑒別塑料嗎？（二）

‘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.
