摘要： The invention relates to a method for testing connections of metal workpieces to plastic compounds for cavities by means of ultrasound, wherein the plastic compound is arranged between the workpiece as an intermediate layer or is connected to the workpiece on one side and the cavity is located within the plastic compound, wherein the cavity is connected to the workpiece by means of a remaining plastic layer or plastic skin and wherein the plastic compound is exposed to ultrasonic signals of a certain test frequency and pulse length from the metal side of the workpiece by means of at least one ultrasonic probe, and in particular the ultrasonic signals reflected by flaws in the plastic compound are detected by the same or another ultrasonic probe and converted into electrical signals that can be evaluated and subjected to a threshold observation. The test frequency of the ultrasonic signals is set in a range of 1 to 10 MHz so that the attenuation of the sound is minimal after passing through the plastic skin.

摘要： Reactive adhesives are prepared based on polyurethane compositions obtained by reacting at least one type of polyol with at least one type of diisocyanate containing at least 80 percent by weight 2,4′-diphenylmethane diisocyanate. Such adhesives are applied to a surface to be glued of at least one substrate, thermally reactivated separately in time and/or space from application of the adhesive, and then used to join together the substrates to be adhered to each other.
摘要翻译：基于通过使至少一种类型的多元醇与至少一种含有至少80重量％的2,4'-二苯基甲烷二异氰酸酯的二异氰酸酯反应而获得的聚氨酯组合物来制备反应性粘合剂。这样的粘合剂被施加到待粘合的至少一个基底的表面上，在施加粘合剂的时间和/或空间中分开热重新激活，然后用于将待粘附的基底彼此连接在一起。
