Precautions for use of metal cleaners

Metal cleaning agents are widely used in industrial production and daily maintenance, which can effectively remove oil, rust and other impurities on the metal surface, and maintain the finish and good performance of the metal. However, when using metal cleaners, the following precautions should be taken to ensure that the cleaning operation is safe and effective.

Metal cleaning agents are composed of surfactants and added cleaning aids (such as alkaline salts), rust inhibitors, defoamers, fragrances, etc. Its main ingredient surfactants include several types, and the domestic ones are mainly non-ionic surfactants, including ether, ester, amide, and polyether, which have strong decontamination ability.

When choosing a metal cleaning agent, you should pay attention to the following points:

<!--[if !supportLists]-->1.<!--[endif]-->Pay attention to the concentration of cleaning agents. First of all, be sure to read the product manual carefully before using metal cleaners. Different metal cleaners may have different compositions and properties, and it is important to understand their scope of application, how to use them, safety precautions, and more. Operate in strict accordance with the requirements of the manual to avoid safety accidents caused by misuse or poor cleaning effect. The concentration of the cleaning agent is closely related to the cleaning effect, and usually when the concentration increases, the decontamination ability is also enhanced, but after reaching a certain concentration, the decontamination ability is no longer significantly improved. Generally, it is advisable to control the concentration at 3%-5%. If the detergent concentration prepared according to the product instruction manual is not satisfactory, the detergent concentration should not be increased, but other formulations of detergent should be selected.

<!--[if !supportLists]-->2.<!--[endif]-->Grasp the temperature of the cleaning agent. In general, as the temperature of the cleaning agent increases, the decontamination capacity also increases, but after a certain temperature, the decontamination ability decreases. Therefore, each cleaning agent has an optimal temperature range, and the higher the temperature, the better. In particular, non-ionic cleaners can become cloudy when heated to a certain temperature, which is called "cloud point".At this time, the solubility of the active agent in water is reduced, some components are decomposed by heat and fail, and the decontamination ability is reduced. Therefore, the temperature of non-ionic cleaners should be kept below the cloud point. Second, we should pay attention to protective measures. Metal cleaners are often irritating and corrosive, and may cause discomfort or injury if they come into contact with the skin or eyes. Therefore, wear appropriate protective gloves, goggles and other protective equipment during use, and avoid direct contact with the cleaning agent. In case of accidental contact with cleaning agents, rinse immediately with plenty of clean water and take corresponding first aid measures according to the specific situation.

<!--[if !supportLists]-->3.<!--[endif]-->Know how long the cleaning agent lasts. A single preparation of cleaning agents can be used multiple times, and its use time depends mainly on the number of parts to be cleaned and the degree of contamination of the cleaning agent, in general, the cleaning agent formulated at one time can be used continuously for 1-2 weeks. In order to save the amount of cleaning agent and improve the cleaning quality, the cleaning sequence should be reasonably arranged according to the characteristics of the parts. For example, cleaning the main parts and the less dirty parts first, and then the secondary parts and dirtier parts can extend the use of the cleaning agent. In addition, it is important to be aware of the differences when using metal cleaners for different types of metals. For example, certain metals may be sensitive to certain cleaner components and are susceptible to corrosion. Tests should be carried out before cleaning to determine the appropriate cleaning agent and cleaning conditions for the metal to avoid damage to the metal.

<!--[if !supportLists]-->4.<!--[endif]-->Pay attention to the type and nature of the dirt on the parts. The types and properties of dirt on auto parts vary greatly, including solid oil stains such as oil sludge, scale, carbon deposits, rust, and liquid oil stains such as lubricating oil and grease residues. Scale and rust are commonly removed with descaling and cleaning agents; Other oils, greases, etc. can be cleaned with heavy oil cleaners. Furthermore, we should pay attention to environmental safety. Metal cleaners may produce harmful gases or volatiles during use, which can be harmful to human health and the environment if not handled properly. Use metal cleaners in well-ventilated areas and avoid prolonged operation in confined spaces. At the same time, properly dispose of the waste water and waste residue generated in the cleaning process, and treat it in accordance with relevant environmental protection requirements to prevent environmental pollution.

<!--[if !supportLists]-->5.<!--[endif]-->Prevent parts from being corroded. For copper, lead, zinc and other parts that are easy to be corroded, as well as parts of precision instruments and meters, it is necessary to choose a cleaning agent that is close to neutral, less corrosive and has strong rust prevention ability.

<!--[if !supportLists]-->6.<!--[endif]-->Consider the cleaning conditions. If there are steam heating conditions, high-temperature cleaning agents can be used; When manual cleaning is mainly used or the parts to be cleaned are not suitable for heating, low-temperature cleaning agents are used; When using mechanical cleaning and pressure spraying, use a low-foaming cleaning agent.

Finally, keep the metal cleaner in a safe place. Store the cleaning agent in a cool, dry and well-ventilated place, away from fire and flammable materials, away from direct sunlight and high temperature environment, to prevent the cleaning agent from deteriorating or dangerous. At the same time, keep the detergent out of the reach of children to prevent accidental ingestion or misuse.

In conclusion, the correct use of metal cleaners is extremely important to keep the metal in good condition and improve work efficiency. Only by strictly adhering to the precautions for use and taking protective measures can metal cleaning agents be used safely and effectively, providing strong support for industrial production and daily maintenance.
