Ultrasonic cleaning machine is not only used in our life, but also in many fields. The key function of the ultrasonic cleaner is cleaning, which makes our life healthier. How much do you know about the standard ultrasonic cleaner? Now let’s introduce the functions of the standard ultrasonic cleaner.
Standard ultrasonic cleaner – cleaning after grinding
Grinding is an important process in optical glass production, which determines its processing efficiency and surface quality (appearance and precision). The main pollutants in the grinding process are grinding powder and asphalt, and a few enterprises will have paint chips in the processing process. Among them, the types of grinding powder are different, generally alkali metal oxides mainly composed of cerium dioxide. Different types of grinding powder are selected according to the different materials and grinding precision of lenses. The asphalt used in the grinding process plays a protective role to prevent the polished mirror surface from being scratched or corroded. Cleaning equipment after grinding can be roughly divided into two types: one mainly uses organic solvent cleaning agent, and the other mainly uses semi water-based cleaning agent.
Standard ultrasonic cleaner – semi water-based cleaning
The biggest difference between this cleaning process and solvent cleaning is that the first two cleaning units: organic solvent cleaning only has a good cleaning effect on asphalt or paint chips, but can not clean inorganic substances such as grinding powder; Semi water-based cleaning agent is different. It can not only clean organic pollutants such as asphalt, but also clean inorganic substances such as grinding powder, which greatly reduces the cleaning pressure of water-based cleaning agent in subsequent cleaning units. Semi water-based cleaning agent is characterized by slow volatilization and low odor. Equipment cleaned with semi water-based cleaning agent does not need to be sealed in the first cleaning unit. However, since the viscosity of semi water-based cleaning agent is relatively high and it can emulsify water-based cleaning agent used in subsequent processes, the second unit must be rinsed with commercial water, and it is better to set it as flowing water rinsing.
Standard ultrasonic cleaner – cleaning after coating
Generally, it includes cleaning before inking, cleaning before jointing and cleaning before assembling, among which, cleaning before jointing (jointing refers to the process of bonding two lenses with photosensitive adhesive into a specified shape to meet the requirements that cannot be processed and formed at one time, or to produce a relatively special curvature and transmittance) is the most strict. The pollutants to be cleaned before jointing are mainly the mixture of dust, fingerprints, etc. It is not difficult to clean, but there are very high requirements for the cleanliness of the lens surface. The cleaning method is the same as the previous two cleaning processes.
The above is the functional knowledge of the standard ultrasonic cleaner. After reading the above introduction, I believe you have more knowledge about the ultrasonic cleaner. We all know that the use of ultrasonic cleaning machine has solved many cleaning problems and made our life healthier. Therefore, in order to make our life better and more comfortable, it is necessary for us to understand its knowledge.
