Abstract

The enamel stripping is carried out in suitable enamel-stripping solutions by ultrasonic means at 20 to 100 degrees C. Ultrasonic treatment is carried out at a pressure of 100 millibars to 10 kbar.

Description

Die Erfindung betrifft ein Verfahren zur Entlackung in geeigneten Entlac­ kierungslösungen mittels Ultraschall. Verfahren der gattungsgemäßen Art zur Entlac­ kung in geeigneten Entlackierungslösungen existieren bereits. Diese bekannten Verfahren sehen die Entlackung im Tauchverfahren bei Raumtemperatur bzw. bei Temperaturen zwischen 40-100°C vor. Neu ist die kombinierte Anwendung dieser Entlackungsverfah­ ren mit einer Ultraschallbehandlung.The invention relates to a process for stripping paint in suitable paint shops marking solutions using ultrasound. Process of the generic type for Entlac suitable paint stripping solutions already exist. This known method see the paint stripping in the immersion process at room temperature or at temperatures between 40-100 ° C. What is new is the combined application of this paint stripping process with an ultrasound treatment.

Der Erfindung liegt die Aufgabe zugrunde, bestehende Entlackungsverfahren durch eine neuartige Kombination mit einer speziellen Ultraschallbehandlung zu optimieren. Der wesentliche Vorteil liegt in einer Verkürzung der Einwirkzeiten sowie in einer Steigerung der Entlackungsleistung. So ist es erstmalig möglich, Polykondensate und Polyadditive zu entlacken. Durch die verkürzten Einwirkzeiten werden die Polykondensate und Po­ lyadditive nur wenig angegriffen und können wiederverwendet werden. Im Fall der Hei­ ßentlackung kann bei deutlich niedrigeren Temperaturen gearbeitet werden, was zu einer Minimierung des Gefahrenpotentials führt.The invention has for its object to existing paint stripping process by optimize a new combination with a special ultrasound treatment. Of the the main advantage is a reduction in exposure times and an increase the paint stripping performance. For the first time it is possible to use polycondensates and polyadditives to remove paint. Due to the shorter exposure times, the polycondensates and Po lyadditive only slightly attacked and can be reused. In the case of the Hei ßentlacking can be worked at significantly lower temperatures, which leads to a Minimization of the hazard potential leads.

Durchgeführte Versuche haben gezeigt, daß nach dem erfindungsgemäßen Verfahren durchgeführte Heiß- und Kaltentlackungen folgende Vorteile gegenüber dem Stand der Technik aufweisen:
Experiments carried out have shown that hot and cold stripping carried out by the process according to the invention has the following advantages over the prior art:

  • - erstmalig können Polykondensate und Polyadditive entlackt werden- For the first time, polycondensates and polyadditives can be stripped
  • - die Einwirkzeiten werden deutlich verringert- The exposure times are significantly reduced
  • - Verbesserung der Entlackungsleistung- Improve paint removal performance
  • - Absenkung der Entlackungstemperaturen im Falle der Heißentlackung.- Lowering the stripping temperatures in the case of hot stripping.

Zur Erläuterung der Erfindung sind nachfolgend einige Beispiele aufgeführt:A few examples are given below to explain the invention:

Beispiel 1example 1

Stoßfänger aus Polyester konnten in 10 min im Ultraschallbad bei 65°C und nachfolgen­ dem Waschgang mit kaltem Wasser vollständig entlackt werden.Bumpers made of polyester could follow in 10 minutes in an ultrasonic bath at 65 ° C and the wash cycle should be completely stripped with cold water.

Beispiel 2Example 2

Aufnahmen für Lackierstraßen konnten in 9 h im Kaltentlackungsverfahren kombiniert mit einer Ultraschallbehandlung entlackt werden, ohne daß es bei empfindlichen Teilen zu einer Formveränderung kam. Dies ermöglicht eine erneute Verwendung der Aufnah­ men im Lackierbetrieb.Recordings for painting lines could be combined in 9 hours using the cold stripping process can be stripped with an ultrasound treatment, without it for sensitive parts came to a change in shape. This enables the recording to be used again men in the paint shop.
