    超聲波焊接的的影響因素有哪些?
    2019-09-13 10:50:16
    聚合物結構非結晶聚合物分子排列無序、有明顯的使材料逐步變軟、熔化 及至流動 的溫度(Tg玻璃化溫度)。這類樹脂通常能有效傳輸超音速振動並在相當廣泛的壓力 振幅範圍內實現良好的焊接。半結晶型聚合物分子排列有序,有明顯的熔點(Tm熔 化溫度)和再度凝固點。固態的結晶型聚合物是富有彈性的,能吸收部分高頻機械振 動。
    Polymer structure of amorphous polymer molecules arranged disorderly, obviously the material gradually become soft, melting and flow temperature Tg (glass transition temperature). This kind of resin is usually able to transmit the supersonic vibration effectively and realize the good welding in the very wide range of pressure amplitude. Semi crystalline polymer molecules arranged in an orderly manner, there is a clear melting point (Tm melting temperature) and re solidification point. Solid crystalline polymers are flexible and can absorb some of the high frequency mechanical vibrations.
    所以此類聚合物是不易於將超聲波振動能量傳至壓合麵,幫要求更高的振幅。需要很高的能量(高熔化熱度)才能把半結晶型的結構打斷從而使材料從結晶狀態變為 粘流狀態,這也決定了這類材料熔點的明顯性,熔化的材料一旦離開熱源,溫度有所 降低便會導致材料的迅速凝固。所以必須考慮這類材料的特殊性(例如:高振幅、接 合點的良好設計、與超音夾具的有效接觸、及優良的工作設備)才能取得超聲波焊接 的成功。
    So this kind of polymer is not easy to the ultrasonic vibration energy transmitted to the pressing surface, help demand higher amplitude. Need very high energy (high heat of fusion) to the semi crystalline structure interrupted so that the material from the crystalline state variable for viscous flow state, which also determines the obvious of the melting point of the material, the molten material once leaving the heat source, the temperature decreased will lead to materials of rapid solidification. Therefore, we must consider the material of this kind of special (for example: high amplitude, ground contact point of good design, and supersonic fixture, and excellent equipment) in order to achieve ultrasonic welding of success.
    聚合物:熱塑性與熱固性將單體結合在一起的過程稱為“聚合”。聚合物基本可分為兩大類:熱塑性和熱固性。熱塑性材料加熱成型後還可以重新再次軟化和成型,基所經曆的隻是狀態的變化而已-這種特性使決定了熱塑性材料超聲波壓合的適 應性。熱固性材料是通過不可逆反的化學反應生成的,再次加熱或加壓均不能使已成 型的熱固性產品軟化,所以傳統上一直認為熱固性材料是不適合使用超聲波的。
    Polymer: thermoplastic and thermosetting monomer combined process is called polymerization". The polymer can be divided into two major categories: thermoplastic and thermosetting. After heating the thermoplastic material, it can be re softened and formed again. The base undergoes only the change of the state. Thermosetting material is generated by chemical reaction of not rebellious, again heat or pressure can make is softening type of thermoset products, so traditional always think thermosetting material is not suitable for the use of ultrasonic.
