Here is the Granbosonic Guidance on selection of cleaning agent for ultrasonic cleaning machine

Ultrasonic cleaning machine is more and more widely used in every industry; Before purchasing the ultrasonic cleaning equipment, users should first make clear that the purpose of the ultrasonic cleaning machine to achieve cleaning depends on the physical cavitation of the ultrasonic and the chemical decomposition and stripping of the ultrasonic cleaning agent. The combination of the two functions can achieve the purpose of cleaning. However, the purchase of the ultrasonic cleaning machine can not achieve the purpose of thorough cleaning, because most of the parts we clean have residual oil and dust on the surface, Fingerprints, processing residues and other pollutants need to be thoroughly cleaned with the help of ultrasonic cleaning agents! What about the ultrasonic cleaner? Granbosonic uses years of experience to tell you if you choose the right ultrasonic agent;

It is necessary to clarify the pollutant components on the cleaned articles;

Types of oil stains on hardware parts: processing oil, cutting oil, tapping oil, stamping oil, stretching oil, polishing wax, grinding powder, engine oil, carbon residue, processing residue, etc

It is necessary to specify the material of the cleaned articles;

Why should we clearly understand the material of the cleaned objects? Different types of cleaning agents need to be selected for different parts’ materials. Copper and aluminum parts are active metals. If water-based cleaning agents are used to clean the surface of parts, oxidation will occur. If electroplating or oxidation treatment is required after cleaning, it doesn’t matter. If parts are shipped directly after cleaning, it is recommended that such metal parts be cleaned with solvents as much as possible; It is recommended to preferentially use hydrocarbon cleaning agent for cleaning, and select vacuum drying or suction drying mode for drying; If water-based cleaning agent is used, it is recommended to use neutral water-based ultrasonic cleaning agent. Passivation treatment is recommended after cleaning and rinsing, and then drying treatment is recommended! Iron and carbon steel parts must be treated with rust prevention after ultrasonic cleaning;

Ultrasonic cleaning temperature needs to be specified

The ultrasonic cleaning temperature is generally 45-60 degrees, and some special pollutants require a cleaning temperature of about 80 degrees; For example, the cleaning temperature of the polishing wax is recommended to be 80 ℃, and the polishing wax of plastic parts is recommended to be cleaned with low-temperature polishing wax cleaner at room temperature to avoid the temperature exceeding 45 ℃, so as to avoid deformation of plastic parts;

Electronic circuit board, pcba, optical glass, TP glass cover plate, prism lens, high-precision parts cleaning, etc. must be rinsed with DI water to avoid water marks on the surface of parts after drying;

It is recommended to use special cleaning agent for cleaning parts of laboratory instruments to avoid corrosion of high-precision parts; It is recommended to rinse and dry the surgical instruments and tools with alcohol detergent after cleaning;

The ultrasonic cleaning instruments in biopharmaceutical laboratories mainly use water as the cleaning fluid. Pay attention to controlling the water temperature and liquid level of ultrasonic cleaning instruments; After the emulsification, degassing and dispersion processes are completed, please turn off the power supply of the ultrasonic cleaning instrument;

It is forbidden to use flammable and explosive hazardous chemicals as cleaning agent when using ultrasonic cleaning machine or ultrasonic cleaning instrument. It is forbidden to put parts directly into ultrasonic cleaning tank. Try to use ultrasonic cleaning basket or bracket for cleaning;

The following is a guide for beginners of ultrasonic machines.

What kind of cleaning agent is used for ultrasonic cleaning machine and how to select cleaning agent for ultrasonic cleaner

As we all know, when purchasing an ultrasonic cleaner, we must first analyze the cleaned workpiece as follows: understand the material composition, structure and quantity of the workpiece, and understand the dirt to be removed. After specific analysis, we can determine what kind of cleaning method should be adopted, and at the same time judge whether to use water-based cleaning agent or solvent. Therefore, the cleaning process of the ultrasonic cleaner should be verified by cleaning experiments, so that the cleaning effect of the ultrasonic cleaner can reach the desired state. However, in addition to these, we should also design a reasonable cleaning process and select appropriate cleaning agents. In addition, the physical characteristics of the cleaning agent should also be considered, because some characteristics will also affect the cleaning effect of the ultrasonic cleaner. Steam pressure, surface tension, viscosity and density should be significant factors. The operating temperature will affect these factors, so it will also affect the cavitation efficiency. It can be seen that the cleaning agent must be used when the ultrasonic cleaner works.

So, what factors should be considered before selecting the cleaning fluid of the ultrasonic cleaning machine? We generally summarize it into the following three types:

First, cleaning efficiency: when selecting an effective cleaning solvent, experiments must be carried out. For example, if ultrasonic wave is introduced into the existing cleaning process, it is generally unnecessary to change the solvent;

Second, simple operation: the liquid used should be safe and non-toxic, simple operation and long service life;

Third, cost: the cost of cheap cleaning solvents is not necessarily low. The cleaning efficiency and safety of the solvent, the number of workpieces that can be cleaned by a certain amount of solvent, and the utilization rate must be considered. Of course, there is also the selected cleaning solvent. In addition to achieving the desired cleaning effect, the more important cleaning solvent cannot react with the cleaned workpiece material. Water is a common cleaning solution, so the system using water-based solution has the advantages of simple operation, low cost and wide application. However, some materials and dirt are not suitable for aqueous solutions, so there are many solvents to choose from.

Tips About Ultrasonic agent

Different ultrasonic cleaning systems shall be selected for different cleaning solutions.

Water system: it usually consists of an open tank in which the workpiece is immersed. If the system is more complex, it is composed of multiple tanks and equipped with circulating filtration system, shower tank, drying tank and other accessories.

Solvent system: it mainly includes ultrasonic gas-phase degreasing and cleaning machine. In addition, it is often equipped with waste liquid continuous recovery device. At present, the new product hydrocarbon cleaning machine, which is environmentally friendly, safe and zero emission, is favored by many enterprises.

In addition, the treatment of clean parts shall be considered. Another factor to be considered in the ultrasonic cleaning machine is the loading and unloading of cleaning parts or the design of tooling. When cleaning the workpiece in the cleaning tank of the ultrasonic cleaning machine, neither the cleaning part nor the cleaning part basket can touch the bottom of the tank. The total cross-sectional area of the cleaned parts shall not exceed 70% of the cross-sectional area of the ultrasonic tank. Rubber and non toughened plastics absorb ultrasonic energy, so care should be taken when using these materials in tooling. Special attention shall also be paid to insulation cleaning parts. If the tooling basket is improperly designed or the workpiece is too heavy, the efficiency of the ultrasonic cleaning system will be greatly reduced. Hooks, shelves, and beakers can be used to support cleaning parts
