1. Fully Automatic: It is a process that is automatically operated by the machine not humans in agricultural and industrial production.
2. What's an ultrasound? Ultrasonic is a sound wave with a frequency higher than 20000 Hz. It has good directivity and strong penetrating ability. It is easy to get more concentrated sound energy. It can travel far in water and can be used for ranging, velocity measurement, ultrasonic cleaning machine, welding, detritus, sterilization, etc. It has many applications in medicine, military affairs, industry, and agriculture. Ultrasound is so named because the lower limit of its frequency is approximately equal to the upper limit of human hearing.
3. What is cleaning? Cleaning refers to the removal of liquid and solid pollutants on the surface of the workpiece. So that the workpiece can achieve a certain degree of cleanliness. The cleaning process is the cleaning medium, pollutants, and the interaction between the workpiece surface. It's a complex physical and chemical process. Cleaning is not only related to the nature, type, shape, and adhesion degree of the contaminant, but also the physical and chemical properties of the cleaning medium. the cleaning function, the material, and the surface state of the workpiece. It is also related to the cleaning conditions such as temperature, pressure, and additional ultrasonic vibration, mechanical factors such as external force. Therefore, the selection of a scientific and reasonable cleaning process is very important. The process analysis must be carried out.
Full-automatic ultrasonic cleaning machine, we explain it in this way, is it clearer?
Under what background did it develop?
In the beginning, the development of the electronic industry has limitations. The automatic ultrasonic cleaning machine was not perfect: 1. Massive power source. 2. The stability is poor and the price is expensive. The general enterprise can not afford it. Then, as development increased in performance and service life, prices also decreased. In the 1980s, with China's reform and opening up and its integration with the world, the economy developed rapidly. The original demand is no longer satisfied with the status quo. Because of these factors and external pressure, the automatic ultrasonic cleaning technology has been forced to make breakthroughs and become more and more perfect. And it is favored by all walks of life. The automatic ultrasonic cleaning machine greatly improves the cleaning efficiency. It is easier to clean the usual dead end and the corner. After so long evolution, today's fully automatic ultrasonic cleaning machine in the technical aspect is more and more advanced. The price is more and more accepted, thus it is widely used.
What is it composed of?
The principle of ultrasonic cleaning is that the high-frequency oscillation signal sent by the ultrasonic generator is transformed into high-frequency mechanical oscillation by the transducer and transmitted to the medium. Tens of thousands of tiny bubbles are produced when the liquid flows. The tiny bubbles in the liquid vibrate under the action of the sound field. When the sound pressure reaches a certain value, the bubbles increase rapidly and then close suddenly. A shock wave is generated when the bubble closes, creating thousands of atmospheres of pressure around it, breaking up the insoluble dirt and dispersing it into the cleaning solution. And when the particles are coated with oil and adhere to the surface of the cleaning part, the oil is emptied, the solid particle and the separation. Thereby it achieves the goal of purifying the cleaning part.
Most of the cleaning agents used in the automatic ultrasonic cleaning machine are liquid detergents, which are made up of surfactants, filler, other additives, and other organic solvents such as trichloroethene.
When a sance is dissolved in water, even at very low concentrations, it can significantly reduce the surface tension between water and air or the interfacial tension between water and other sances. The molecular structures of water-soluble surfactants are characterized by asymmetric polarity. The adsorption on the interface between the aqueous solution and other phases greatly changes the physical properties of the system, especially the interfacial tension of each phase. The surface-active agents can be divided into anionic, cationic, neutral, and amphoteric surface-active agents according to the electric properties of the hydrophilic group when the surface-active agent is dissolved in water. Chelating agents and some metal ions in solution such as ca 2 + mg 2 + form a stable chelating body so that the detergent has the function of hard water resistance. It can also be combined with some Ca2 + Mg2 + containing sances on the surface of the lens to achieve the cleaning effect.
The addition of certain auxiliaries serves the following purposes:
Buffer action: make the PH value of detergent can maintain stability.
Resistance to corrosion of metals.
It can increase the emptying ability and emptying stability of detergent.
The invention can make the solution have good suspension ability and the ability to stabilize the suspension system, and can prevent the dirt from settling again.
The selection principle of exterior active agent, chelating agent, and auxiliary agent: 1 The detergent composed of has a strong cleaning ability; 2 the chemical property is gentle and does not damage the washed object; 3. There is no chemical reaction between the components to render them useless. 4. components have good bleaching properties.
The use temperature and concentration of the washing liquid should be determined by specific experiments. The purpose of the trichloroethene is to clean it by dissolving it in glue, wax, and pitch.
