1. How to choose a product?
One should complete the product selection form and send it to us by email: biuro@gt85.com.pl or by fax: 081 745 12 95.
Having received the form, our employee will contact you and provide additional information.
2. How to place an order?
Orders are received via email at biuro@gt85.com.pl or by fax 081 745 12 95. Orders placed before 1 a.m. are dispatched on the same day. Standard order handling takes up to 48 h.
3. When should the bath be replaced?
The bath has been used up if the effects of washing are unsatisfactory or when the bath is saturated with impurities. The bath should then be replaced with a new one.
4. What is the optimal temperature for ultrasonic washer operation?
Most preparations for ultrasonic washing operate at a temperature of 50-60 °C
5. What is the meaning of the term “sound”?
All that can be perceived by hearing is described as sound. Human hearing can perceive sounds of the frequency between 16 hertz and approximately 18,000 hertz (18 kHz). 1 hertz = 1 vibration per second.
Sound can propagate only in flexible environments. These include solids, liquids and gases. Sound cannot propagate in vacuum. Sound waves cause periodic phases of overpressure and underpressure in the medium they propagate in. The speed of sound and the form of its propagation depend on the medium (sound conductor).
6. What are ultrasounds?
The notion of ultrasounds includes all sound waves that are beyond the range of human perception. It is known that liquids take their form due to forces of intermolecular attraction (cohesion). In the case of a constant rise in ultrasound intensity in the liquid, it is partially transformed into vapour in the underpressure phase and microscopic bubbles of vapour are formed.
In the subsequent overpressure phase these vapour bubbles implode. During this process, extremely big forces occur, which leads to the appearance of micro-shock waves and microflows.
This physical process of “vapour cavitation” also has other applications, in which high underpressure phases act on liquid, e.g. in the case of screw propellers or turbines.
7. What does cavitation depend on?
Cavitation depends on many parameters. These are external pressure, temperature, sound frequency and intensity, type of liquid and other acoustic parameters.
Finally, cavitation creates the perfect cleaning effect, similar to that of using many microscopic brushes.
