Conventional industrial cleaning generally uses solvent-based cleaning agents, and toxic and harmful solvent cleaning agents such as trichloroethylene have been eliminated. Therefore, environmentally friendly solvent cleaning agents have directly replaced their applications. For example, environmentally friendly hydrocarbon cleaning agents have been widely used. However, with the development of the economy, the reduction of industrial production costs is what every company is pursuing. New water-based cleaning agents have gradually been recognized and valued by enterprises. Water-based cleaning agents have gained recognition for their environmental friendliness, lower cost and higher efficiency.
If you have been using solvent-based cleaners before, what problems do you need to consider when you want to use water-based cleaners instead? How do you choose a water-based cleaner that suits your company's requirements? We stand in your perspective to analyze them one by one.
The first consideration is that the materials of industrial production are diversified, including stainless steel, copper, aluminum, iron, alloy, and plating. So is your product material suitable for washing? Does the cleaning process affect the material? For example, is it easy to rust when washed with iron or the like, and will copper, aluminum, etc. be oxidized and discolored after washing? The problem with the practical application of many water-based cleaning agents is that some companies have been skeptical and worried. In fact, the development and application of water-based cleaning agents has been a long time. The application of water-based cleaning agents in foreign countries and solvent-based cleaning agents can be said to be the same starting line. All aspects of technology have been relatively mature, but only in China. Marketing has started slowly. How to protect the active metal during the washing process to prevent the reaction from occurring, this problem no longer exists. If the material such as cast iron is easy to rust when it is in contact with water, the water-based cleaning agent should be rust-proof, which can protect the material from rust and corrosion while cleaning. This kind of water-based cleaning agent is used by various large casting processing enterprises. . For example, copper materials may change color when the pH changes. The targeted copper water-based cleaning agent should be selected, which can be cleaned without affecting the properties of the copper itself. The white copper cleaning is a lot of examples.
Secondly, when considering the applicability of the material, we should return to the application conditions of the enterprise itself. What kind of application conditions should be used for the water-based cleaning agent, and do not need equipment? Water-based cleaning agents generally need to be heated. In order to enhance the cleaning effect, many enterprises also apply ultrasonic cleaning equipment. However, depending on the surface of the product and the customer's requirements, cleaning equipment is not required. Then according to your own situation, you should consider whether your company currently has cleaning equipment, it is best to ask the water-based cleaning agent suppliers to see if they need to use the equipment. If there is an ultrasonic device then it is suitable to use a water-based cleaner. For example, you have an ultrasonic cleaning device before, and there are three internal grooves in the structure of the device. Is this suitable for the water-based cleaning process? The answer is yes, but process improvement is needed. After the improvement, the three inner tanks are divided into three stations, the first tank is added with a cleaning agent for decontamination cleaning, and the second and third are used for rinsing. The processed workpieces are then dried. This is the case when there is already equipment. If there is no equipment to consider purchasing cleaning equipment, of course, this is more to consider the equipment cost problem. We will discuss and discuss this issue in detail later.
Then, knowing the choice of cleaning agent and the understanding of the equipment situation, the next important thing is the feasibility of the actual water-based cleaning agent application of the specific enterprise. Is it really suitable for washing? The answer is: practice. There is no one hundred percent water-based cleaner. Due to the different types of products in each application unit, it is necessary to adjust the water-based detergent formulation for each specific application. So choose a water-based cleaner manufacturer with technical research and development capabilities to provide product suitability experiments and also advise you on the washing process you will use. But please bear in mind that everything is empty and practice is the test of truth.
Here is a real case:
A certain metal stamping product manufacturing factory in Shenzhen Longgang has received a batch of processing orders for stainless steel stamping parts. The customer has higher requirements on the surface of the product, and it is not allowed to have surface defects such as dirt, scratches and deformation. After the introduction of the peers, the factory contacted me Changlufeng Chemical Company to convey the cleaning requirements of the batch of products. Our company directly dispatched customer service personnel to the factory to conduct face-to-face negotiations. After the customer service arrived at the factory, they communicated with their manager Lin.
First of all, we communicated that the batch of materials is made of SUS304 stainless steel, the surface is dirty, the punching oil added during the processing, and some oil and dust stuck on the mold.
Our customer service staff introduced to Lin Manager that there are two methods of cleaning. One is solvent-based cleaning and the other is water-based cleaning. Since the plant has not had a cleaning process project before, Lin Manager has not been exposed to the cleaning process project, so his first question is which of the two cleaning methods is good, how the effect and application cost compare, what kind of process or device?
The customer service staff responded to Lin Manager with a more realistic response. If the product order is long-term and needs to be disposed of in the future, then we recommend a water-based cleaner. The water-based cleaning agent method uses a water-based cleaning agent as a concentrated liquid, and needs to be watered to a concentration of 2-5% when used, so the cost is relatively low. However, the use of water-based cleaning agents, the process is more, especially the subsequent rinsing according to the requirements of the customer's requirements, the surface can not see any dirt under strong light and dark light, so it is also necessary to use industrial pure water rinsing. Therefore, if long-term cleaning is required, it is better to consider the use of water-based cleaning agents from the overall cost, and the short-term demand is not cost-effective. If the product quantity is small and short-term, then we recommend a solvent-based cleaner. The solvent cleaning agent is used as a stock solution, and the cost per unit is relatively high, but the number of steps is relatively small. Therefore, it is more cost-effective to use a solvent type in the case where the short-term single amount is small.
Manager Lin said that the order is long-term, and the amount of cleaning required per day is about 100K, so the customer service staff recommended it to use water-based cleaning agent. Then, according to the company's situation, how to use the water-based cleaning method? According to the company's actual application of water-based cleaning agent, it needs to be designed as multi-tank. The process can be designed as: ultrasonic heating and rough washing - ultrasonic heating and fine washing - municipal water rinsing - municipal water rinsing - pure water rinsing -dry. Of course, this requires further practical feasibility testing. If the product surface requirements are not up to standard, in order to enhance the effect, spray rinsing and wind cutting water can be added in the middle. In the previous two ultrasonic cleaning processes, if one can be cleaned by experiment, only one ultrasonic cleaning can be used. The post-order pure water needs to be produced by an industrial pure water machine, but some customers can use the filtered water to meet the requirements.
After that, Manager Lin had a certain understanding of the project. However, our customer service staff adhere to the principle of "seeking truth and being pragmatic", let the customer contact and understand the real situation, and explain everything. After communicating with Manager Lin, we agreed on a time-based simulation experiment on the feasibility of the water-based cleaning agent.
At the experimental site, we first cleaned the product workpiece according to the general process. After the result came out, the manager of the forest judged that the product cleanliness reached the required standard. Next, our customer service staff simplified the cleaning process, using only one ultrasonic cleaning process, and the results of the manager Lin expressed satisfaction. Then, the final decision was made to use a simplified water-based cleaning process: ultrasonic cleaning - rinsing - rinsing - pure water rinsing - drying.
The case is ultimately a win-win result, and the two sides have been happy to cooperate.
