Precautions for the use of ultrasonic automatic cleaning machine
(1) The power supply of the ultrasonic automatic cleaning machine and the power supply of the electric heater must have a good grounding device.
(2) It is strictly forbidden to start the ultrasonic automatic cleaning machine without cleaning liquid, that is, the cleaning tank does not add a certain amount of cleaning liquid, and the ultrasonic automatic switch is not allowed.
(3) For cleaning equipment with heating equipment, it is strictly forbidden to turn on the heating switch when there is no liquid.
(4) It is forbidden to hit the bottom of the cleaning cylinder with heavy objects (iron pieces) to avoid damage to the energy converter chip.
(5) The power supply of the ultrasonic automatic generator should use a single 220V/50Hz power supply and be equipped with a voltage stabilizer above 2000W.
(6) The bottom of the cleaning tank should be cleaned regularly, and there should be no excessive sundries or dirt.
(7) Every time the new fluid is replaced, the parts can be washed only after the ultrasonic wave is automatically started.
Selection of related cleaning agents for ultrasonic automatic cleaning machines:
When discussing the preparation of ultrasonic automatic cleaning agents, we must first think of the cleaning principle and cleaning process of cleaning agents on dirt. Although the washing history is long, but due to the high complexity of the washing process and system, the theoretical circles still only have theoretical research on it, and it is difficult to achieve data control on the washing process. This is due to the fact that the solution system is a heterogeneous dispersion system. The dispersion medium is a complex solution containing a wide variety of components: the surfaces and interfaces involved in the system, as well as the nature of the dirt, are extremely complex.
The cleaning agents used in ultrasonic automatic cleaning machines are mostly liquid detergents, and the composition mode is: surfactants, additives, and other additives. When a substance dissolves in water even if the concentration is very small, it can significantly reduce the surface tension between water and air, or the interfacial tension between water and other substances, then the substance is called a surfactant. The molecular structures of water-soluble surfactants all have asymmetrical and polar characteristics. There are both hydrophilic and lipophilic groups in the molecule. Because of this asymmetrical polar structure, the surfactant is directional adsorbed on the interface between the aqueous solution and other phases, which greatly changes the physical properties of the system, especially The interfacial tension of each phase interface. Surfactants can be divided into anionic, cationic, neutral and amphoteric surfactants according to the electrical properties exhibited by the hydrophilic group when the surfactant is dissolved in water.
The entry of some additives restores the following functions: 1. Buffering effect: the pH value of the detergent can be kept stable. 2. Anti-corrosion effect on metal. 3. It can improve the emulsification ability and emulsification stability of detergent. 4. It can make the solution have good suspension ability and the ability to stabilize the suspension system, which can prevent the dirt from settling again. Selection rules for surfactants, chelating agents, and auxiliaries: (1) The combined detergent has strong cleaning ability; (2) The chemical properties are mild and will not damage the washed objects; The effect makes the components ineffective; (4) has good rinsing properties. The temperature and concentration of the prepared washing solution should be determined by careful experiments. The function of the solvent-based cleaning agent is to achieve the cleaning purpose by dissolving the glue, wax, and asphalt on it. Therefore, in ultrasonic automatic cleaning, it is necessary to select the appropriate cleaning agent according to the characteristics of the dirt of the cleaning object. Only by selecting the appropriate cleaning agent can the ideal cleaning effect be achieved.
