Selection of cleaning agent for ultrasonic cleaning machine:
The extensive application of ultrasonic cleaner in industrial cleaning field is inseparable from the contribution of ultrasonic cleaner. That is to say, the mechanical and physical effects of ultrasound are combined with the chemical dissolution and softening of ultrasonic cleaner, so that the ultrasonic cleaner can achieve the best cleaning effect in the cleaning process. Because the cleaning objects vary from industry to industry, the nature and degree of the dirt, the requirements for surface corrosion inhibition or rust prevention after cleaning, and the requirements for cleaning quality and economic effect are different. Therefore, the selection of cleaning agents for ultrasonic cleaners must be based on specific conditions and specific analysis and comprehensive selection.
Usually, the cleaning agents used in ultrasonic cleaning machine can be divided into solvent cleaning agent and water-based cleaning agent.
1. Water-based cleaning agent is water-based cleaning products. Water-based cleaning agent is generally used in the use of ultrasonic cleaning machine. If water-based cleaning agent does not have anti-rust function, it will speed up the rusting of cleaning products. The reason is that removal of the surface maintenance layer after cleaning will speed up embroidery. If there is a requirement for anti-rust, water-based detergent with anti-rust function should be selected. Everything has advantages and disadvantages. If some components with anti-rust are added to water-based products, these components may reduce the cleaning function of water-based detergent, and its cleaning power may decrease. Water-based detergents have many advantages over organic solvent based products, such as low price, safe and convenient use. The biggest difference between water-based detergents is the need to rinse and dry after cleaning with an ultrasonic cleaner, which usually requires new equipment. These devices can be used in both large-scale production and small batch applications. Such equipment usually pays less than a year in return for investment, after which it can become a truly cost-effective cleaning method. Therefore, if the ultrasonic cleaning machine in use requires lower cleaning costs, volatilization of cleaning is not required, and is not sensitive to rust, water-based cleaning agent can be selected.
2. Solvent detergents generally refer to organic solvents that can volatilize quickly. They are mainly divided into hydrocarbons and chlorinated organic compounds. Hydrocarbon solvents have relatively low toxicity, good material compatibility, multiple volatilization rates and multi-temperature ignition points. Chlorinated organic solvents are relatively toxic and have poor compatibility with materials, but they can be dried quickly and are not easy to burn. In large-scale production, these two organic solvents generally require professional ultrasonic cleaners to meet the needs of anti-virus or problems caused by their ignition point. Solvent cleaning agent has the advantages of high cleanliness, no drying, and the solvent itself can be recycled by distillation. In addition, it solves the problem of difficult treatment of water-based cleaning agent waste liquid, and does not need additional investment in waste liquid treatment equipment. If the cleaning object requires fast volatilization, high cleaning efficiency and rust-proof requirements, solvent cleaning agent can be considered. The disadvantage is high cost and flammability. In addition, the odor of solvents can affect the working environment, especially when using semi-automatic ultrasonic cleaner which is not closed. Selection Principle of Cleaning Agent for Ultrasound Cleaner
There are many kinds of industrial cleaners used in ultrasonic cleaners, but there are no all-round cleaners. They are all special cleaners. They should be based on the material, cleaning requirements and dirt of the cleaned objects. It is better to use the ultrasonic cleaner to carry out technological tests, and then select them. However, several points should be considered in the selection:
(1) The main components of cleaning agent;
(2) The physical properties of the cleaning agent;
(3) Main characteristics of cleaning agents and matters needing attention;
(4) Scope of application of cleaning agents (main uses, dirt objects, etc.);
(5) Cleaning conditions, methods and implementation possibilities of cleaning agents;
(6) Discharge and waste liquid treatment methods;
(7) The cost of cleaning agent;
(8) Laws and regulations on cleaning, etc.
The problems that should be paid attention to in the use of supersonic cleaning agent are as follows:
1. The cleaning agent of the ultrasonic cleaning machine can be recycled. This cleaning method can save a lot of cleaning agents. After each use of the ultrasonic cleaning machine, it is better to put the cleaning agent into the container, and then pour into the cleaning tank when the next use, the remaining sediment can be disposed of. If the concentration of detergent is not enough, a small amount of the detergent can be added to reuse.
2. Knowing as much as possible about the physical characteristics of the cleaning agent can greatly improve the cleaning efficiency of the ultrasonic cleaner. For example, the cleaner with low viscosity is suitable for clearance cleaning; the cleaner with low boiling point has more volatilization loss, but it is suitable for steam cleaning; the selection of appropriate temperature according to different cleaning agents has a great influence on the cleaning effect, etc.
3. Waste liquid treatment. Taking the water system cleaning agent as an example, because the waste liquid of the ultrasonic cleaning machine contains grease and dirt, mud and sand, coke deposit, metal chips and polar oxides, etc., the water quality does not meet the discharge standards, so it should be treated. The general treatment can be divided into three steps:
(1) Settling and filtering by physical method to remove suspended matter, oil slick and sediment;
(2) Oil separation is achieved by combining demulsification oil, salting out, condensation, air flotation and electrolysis.
(3) Wastewater purification can be carried out by biochemical method, ozone method, sand filtration activated carbon adsorption method, etc.
The wastewater treated by three-stage process can meet the national wastewater discharge standard.
