metal finishing treatment agent is a general term for various chemical agents used to treat metal finishings
including cleaning agents, rust inhibitors, phosphating solutions. It is mainly used for substrate pretreatment such as oil removal, rust removal, phosphating, rust prevention, to prepare for metal coating technology and metal protection technology. Therefore, before making custom metal parts, you can first understand the usage scenario and requirements of your project, and then choose which surface treatment method to use. Next, Mulan Group sheet metal processing service provider will provide a detailed introduction to metal finishing treatment agents as follows:
1. Cleaning agent:
used to remove grease, dirt, and impurities from metal finishings. Common cleaning agents include petroleum based cleaning agents (such as solvent gasoline, kerosene, or light diesel) and chlorinated hydrocarbon based cleaning agents (such as trichloroethylene and carbon tetrachloride). Petroleum based cleaning agents mainly clean by dissolving grease, while chlorinated hydrocarbon based cleaning agents are commonly used for steam degreasing due to their low boiling point and volatile characteristics.
2. Rust inhibitor:
used to prevent metal rusting, divided into water-soluble rust inhibitors and oil soluble rust inhibitors. Water soluble rust inhibitors such as sodium nitrite, potassium dichromate, etc. prevent corrosion by reacting with metals to form dense oxide films. Oil soluble rust inhibitors form protective films on metal finishings by adsorbing polar groups, commonly including sulfonic acid salts, carboxylic acids and their soaps, esters, amines, and sulfur and nitrogen heterocyclic compounds.
3. Electroplating solution and chemical plating solution:
used to deposit a layer of metal or alloy on a metal finishing to improve its corrosion resistance, wear resistance, and aesthetics. Electroplating solutions include chrome plating, nickel plating, gold plating, etc., while chemical plating solutions are used for surface treatment under non electrolytic conditions.
4. Cutting fluid and polishing agent:
Cutting fluid is used for lubrication and cooling in metal processing, reducing tool wear and workpiece deformation. Polishing agents are used to improve the smoothness and brightness of metal finishings, and common treatment methods include electrolytic polishing and chemical polishing.
The above treatment agents play an important role in industrial applications, significantly improving the performance and appearance of metal products. The selection of appropriate treatment agents should be determined based on specific application requirements and material properties.
Of course, choosing the appropriate metal finishing treatment agent is a process involving multiple factors. Below, we will explore some key considerations that can help us use it when making custom metal parts. Of course, if you are looking for a professional sheet metal factory to process, the factory will provide you with professional advice, so don’t worry.
Understand the metal material and surface condition
1. Metal material: Different metals have different requirements for treatment agents.
For example, metals such as steel, iron, aluminum, and copper require different types of treatment agents due to their differences in chemical and physical properties.
2. Surface condition:
The cleanliness, roughness, and degree of oil stains on the metal finishing can all affect the selection of treatment agents. For example, for metal finishings with heavy oil stains, it may be necessary to choose cleaning agents with strong degreasing properties.
Clarify the performance requirements of the treatment agent
1. Active agent content:
Active agents are key components of metal finishing treatment agents, and their content directly affects the treatment effect. Therefore, when selecting a treatment agent, it is necessary to understand whether its active agent content meets the treatment requirements.
2. Corrosion inhibitor type:
Corrosion inhibitors can slow down the corrosion rate of metals, and different types of corrosion inhibitors have different adaptability to different metals and environmental conditions. Therefore, it is necessary to choose the appropriate type of corrosion inhibitor according to the specific situation.
3. Processing time and temperature:
Different processing agents have different requirements for processing time and temperature. When choosing a treatment agent, it is necessary to understand its recommended treatment time and temperature range to ensure the treatment effect.
4. Process operating conditions:
Select suitable treatment agents based on specific production processes and operating conditions. For example, for metal finishings that require spraying, electroplating, or heat treatment, appropriate treatment agents need to be selected.
Consider processing costs and processing efficiency
1. Processing cost:
including the price and usage of treatment agents, energy consumption during the treatment process, and costs of wastewater and exhaust gas treatment. When selecting treatment agents, it is necessary to consider these factors comprehensively in order to choose products with high cost-effectiveness.
2. Processing efficiency:
Efficient processing agents can quickly improve the properties of metal finishings and increase production efficiency. Therefore, when choosing a treatment agent, it is necessary to understand whether its treatment efficiency meets production requirements.
Pay attention to the quality standards of processing agents
1. Clear ingredients:
Manufacturers must clearly indicate the proportion and formula information of the processing agent to ensure that all raw materials comply with relevant national regulations and standards.
2. Stable performance:
including the long-term stability of key properties such as corrosion resistance, rust prevention, and adhesion of the product. These performance indicators need to undergo rigorous testing and validation to ensure they meet industry standards and usage requirements.
3. Environmental requirements:
With the increasing awareness of environmental protection and the introduction of relevant policies, metal finishing treatment agents need to meet environmental requirements. When choosing, attention should be paid to whether it adopts advanced production processes and technological means to reduce wastewater, exhaust gas emissions, and solid waste generation.
4. Security of use:
Ensure that the safety and health of users are not compromised or threatened in any way.
Reference application areas and successful cases
Application areas: Understand the application of treatment agents in different fields, such as automotive manufacturing, home appliance manufacturing, industrial manufacturing, etc. These fields have different performance requirements for treatment agents, which can provide reference for selection.
After reading the above introduction to metal finishing treatment agents. We know the types of metal finishing treatment agents and the corresponding treatment processes. Choosing the appropriate metal finishing treatment agent requires comprehensive consideration of factors such as metal material, surface condition, performance requirements of the treatment agent, treatment cost and efficiency, quality standards, application fields, and successful cases.
