Low temperature plasma cleaning steps process detailed.

In industrial production and daily life, cleaning is an essential task. With the development of science and technology, low temperature plasma cleaning technology is gradually widely used in various fields, such as electronics, aviation, automotive and so on. This article will give you a detailed introduction to the step-by-step process of low temperature plasma cleaning to help you better understand the charm of this technology.

Equipment preparation

1. Low temperature plasma generator: This is the key equipment for low temperature plasma cleaning, which is generally composed of power supply, discharge tube, reaction chamber and other parts. The power supply provides a stable DC voltage to the generator, the discharge tube is responsible for generating a high-frequency pulsed electric field, and the reaction chamber is where the plasma is generated and stabilized.

2. Cleaning machine: According to the actual needs, you can choose different types of cleaning machine, such as handheld, desktop or automatic production line equipment. These devices usually include parts such as control systems, delivery systems and spray systems.

Treatment before cleaning

1. Filter the cleaning objects: the items that need to be cleaned are screened according to the characteristics of material, shape, etc., in order to adopt targeted cleaning methods.

2. Oil removal pretreatment: For items with serious oil pollution, oil removal pretreatment can be performed first. Commonly used methods are chemical methods (such as pickling, alkali washing) and electrochemical methods (such as electrolytic degreasing).

low temperature plasma cleaning process

1. Turn on the air source and power supply.

2. Open the power supply of the low-temperature plasma generator, so that the discharge tube generates a high-frequency pulsed electric field. Electrons in the electric field collide with oxygen molecules, forming a plasma. Pay attention to control the discharge frequency and intensity to avoid damage to the cleaning object.

3. Put the items to be cleaned into the reaction chamber, so that the plasma evenly covers the surface of the items. The reaction time depends on the degree of oil pollution and cleaning requirements of the item, generally between tens of seconds to a few minutes.

4. After cleaning, turn off the power and air supply.

low temperature plasma cleaning after processing

1. For some special materials, such as metal, rubber, etc., may need to be dried or high-temperature roasting treatment to remove residual organic solvents and other substances.

2. For some high-precision optical devices, electronic components, etc., you can use a microscope and other tools to check to ensure that the cleaning effect meets the requirements.
