There are many manufacturers producing metal cleaning agents, but the cleaning effect of their products varies greatly depending on the brand. People often have no idea when choosing and don't know which one to choose. In the end, if you randomly choose to use one, but find that the effect is not good, mistakenly thinking that this is a quality issue with metal cleaning agents, how to choose the right metal oil cleaning agent for yourself has always been the most headache for enterprise procurement. So, what are the things we must know when choosing? Technical experts will answer for you:
1. Before selection, it is necessary to understand the composition and type of oil stains to be cleaned. Suitable metal cleaning agents should be selected based on the type of oil stains. For example, the types of oil stains on automotive parts mainly include natural coke, rust proof oil, lubricating oil, grease, rust, sweat stains from workers, and other liquid residues.
2. Avoid corrosion of mechanical components and equipment caused by cleaning agents. In the mechanical industry, due to special requirements, the composition of workpieces varies, such as copper, lead, zinc, etc., and these parts are most prone to corrosion. For example, workpieces with sensitive materials such as precision instruments, meters, and accessories may have certain requirements for the anti-corrosion properties of cleaning agents.
3. Centralize the cleaning of components, select appropriate proportions, and increase the cleaning concentration accordingly, while also improving the ability to remove dirt. The general cleaning concentration shows that the cleaning ability of the components is not significant. When the concentration reaches a certain level, the cleaning ability will increase.
4. Understand and master the temperature of metal industry cleaning agents. During the cleaning process of cleaning agents, there is a heating process, during which the cleaning ability gradually becomes stronger. But beyond a certain temperature limit, the cleaning agent's ability to remove dirt will decrease and eventually lose its ability to remove dirt. Therefore, each different cleaning agent has its own optimal temperature range, and the higher the temperature, the better the cleaning agent's ability to remove dirt. Especially some cleaning agents contain non-ionic substances. When heated to a certain temperature, the cleaning agent will become turbid, and this temperature is called the "cloud point". In autumn, some elements are lost due to the decomposition of water-soluble active agents. Therefore, the cloud point temperature of non-ionic cleaning agents should be controlled below.
5. Use cleaning agents according to the prescribed usage time. A cleaning agent can be used on various metal components, and the duration of use depends on the contamination of the components and the cleaning method. Under normal circumstances, solvent based metal cleaning agents can be used repeatedly.
