In the laboratory, ultrasonic equipment is widely used for a variety of cleaning tasks, including the cleaning of oxides. This article will introduce the method of cleaning oxides by laboratory ultrasonic equipment, including cleaning principles, cleaning steps and precautions.

First, the principle of cleaning.
The principle of ultrasonic cleaning of oxide is mainly to use the energy of ultrasonic waves to produce strong vibration and high-speed jet, so that the dirt, dust and impurities on the surface of the oxide are subjected to strong impact and friction, so as to be effectively removed. At the same time, the cavitation effect of ultrasonic waves can also form tiny bubbles on the oxide surface, which create a stronger impact when they burst quickly, further cleaning the oxide surface.
Second, the cleaning steps.
1.Preparation.
Before you start cleaning, you need to prepare the materials and tools you need, including an ultrasonic cleaner, cleaning agents, lab utensils, gloves, and protective glasses. At the same time, it is important to ensure that the laboratory environment is clean and tidy to avoid affecting the cleaning effect.
2.Cleaning agent selection.
Choose the appropriate cleaning agent according to the nature of the oxide and the degree of contamination. For some common oxides, such as metal oxides, silicates, etc., cleaning agents such as acids, alkalis, or organic solvents can be selected. When choosing a cleaning agent, you need to consider its impact on the environment and the human body, and try to choose an environmentally friendly and low-toxicity cleaning agent.
3.Cleaning operation.
Pour the cleaning agent into the ultrasonic cleaner and dilute it with an appropriate amount of water. Place the oxide to be cleaned in the cleaning basket and place it in the ultrasonic cleaner. Set the appropriate ultrasonic frequency and time to start the ultrasonic cleaner. During the cleaning process, the changes of the oxide should be observed, and the cleaning should be stopped in time if any abnormalities are found.
4.Post-cleaning treatment.
After cleaning, remove the oxide and rinse it with clean water. If further processing is required, it can be dried using a hair dryer or drying oven. After treatment, store the oxide in a dry, dark place to avoid re-contamination.
3. Precautions.
1.When using the ultrasonic cleaner, make sure that the power cord is well connected to avoid safety accidents such as leakage. At the same time, it is necessary to ensure that the washing machine is placed smoothly to avoid accidents such as tipping.
2.When using cleaning agents, wear personal protective equipment such as gloves and protective glasses to avoid causing harm to the human body. At the same time, it is necessary to ensure that the cleaning agent is stored in a cool, dry place to avoid safety accidents such as leakage.
3.During the cleaning process, the changes of the oxide should be closely observed, and the cleaning should be stopped in time if any abnormalities are found. At the same time, it is necessary to regularly check the operation of the ultrasonic cleaner, and repair or replace the parts in time if a fault is found.
4.After cleaning, the cleaning agent should be properly disposed of to avoid harm to the environment and the human body. At the same time, the ultrasonic cleaner should be regularly maintained and maintained to ensure its normal operation and use effect.
