One-piece ultrasonic cleaning machine is now the first choice of industrial cleaning is mainly due to the cleaning equipment can use the cavitation effect for good clean, large and small objects in our daily life plays a very important role in production, so in order to better use of the equipment, the following will give you answer this general method of cleaning products.
1. Cleaning after grinding.
Grinding is an important process in the production of optical glass to determine its processing efficiency and surface quality (appearance and precision). The main pollutants in the grinding process are grinding powder and bitumen. The types of grinding powders are different, generally the alkali metal oxides mainly with cerium dioxide. Depending on the material of the lens and the grinding accuracy, different types of grinding powder are selected. The asphalt used in the grinding process is protective to prevent the mirror of the polished ultrasonic cleaning machine from being scratched or corroded. After grinding, the cleaning equipment can be divided into two types: one is mainly organic solvent cleaning agent, and the other one mainly USES semi-water-based cleaning agent.
2. Cleaning before coating.
Cleaning before coating is the main pollutant of the o core oil (also called edge grinding oil, core is also known as the core, core, refers to in order to get the core radius and precision of the rules and choose process), fingerprints, dust, etc. Because the coating process is very strict to the cleanliness of the lens, the choice of cleaning agent is very important. While considering the cleaning ability of some kind of cleaning agent, it is necessary to consider his corrosive and other aspects.
Generally includes paint ink cleaning, joint before the cleaning and assembly before cleaning, including joint before cleaning (joint refers to the two pieces of lens with photosensitive adhesive into the shape of a regulation, to satisfy the needs of a cannot processing molding, or create a relatively special curvature, a process with the light transmittance) is the most demanding. Joint should be clean before pollutants is mainly a mixture of dust, fingerprints, etc, are not very difficult to clean, but for the lens surface cleanliness have very high demand, the cleaning method is the same as the front two cleaning process.

Selection of frequency of ultrasonic cleaning machine:
The ultrasonic cavitation threshold is closely related to the frequency of ultrasonic wave, and the higher the frequency, the higher the cavitation valve. In other words, the frequency is low, the easier cavitation, and under the condition of low-frequency liquid by compression and sparse effect has a longer time interval, the bubbles grow to larger size before collapse, increase strength, high cleaning effect. Therefore, the low-frequency ultrasonic cleaning is suitable for the surface of the large part or the surface of the cleaning part.
