Our results exhibited that the coatings enhanced the anti-corrosion performance of SS substrates. It was also obtained that the combination of GPTMS/MTMS/APS provided better corrosion protection properties and acts as a strong physical barrier to the corrosive molecules.
In the transportation and storage processes of modern industry, iron drums, as a traditional packaging material, are widely used due to their low cost and strong durability. with the continuous development of the chemical industry, some chemicals have increasingly significant corrosive effects on iron drums. Among them, silane coupling agents, as one of the commonly used surface treatment agents, have attracted attention due to their corrosive properties. This article aims to explore the corrosive effects of silane coupling agents on iron drums and propose corresponding protective measures.
Silane coupling agents are compounds containing siloxane bonds and organic groups, widely used in surface modification treatments of metals to improve material adhesion performance, corrosion resistance, etc. silane coupling agents also pose potential corrosion risks, especially when iron drums are exposed to certain specific environmental conditions.
Firstly, the siloxane bond in silane coupling agents may undergo a chemical reaction when in contact with the surface of iron drums, potentially destroying the oxide layer on the surface of the drums and thereby accelerating the corrosion process. Additionally, the organic groups in silane coupling agents may react with other substances on the surface of the iron drums, further increasing the corrosion rate.
Secondly, silane coupling agents have a strong volatility. During use, they may disperse into the air and react with contaminants on the surface of the iron drums, forming new corrosive media, thus intensifying the degree of corrosion.
To address these issues, the following protective measures can be taken:
- Select appropriate silane coupling agents: When choosing silane coupling agents, those with lower volatility and less corrosive properties should be selected to minimize damage to iron drums.
- Control the usage environment: During the use of silane coupling agents, ensure good ventilation to prevent the accumulation of volatile substances in confined spaces, which could harm the iron drums.
- Regular inspection and maintenance: For iron drums used over long periods, regular inspections and maintenance should be conducted to promptly detect and repair damage caused by silane coupling agent corrosion, preventing further expansion of corrosion problems.
- Use anti-corrosion coatings: Applying an anti-corrosion coating to the surface of iron drums can effectively isolate direct contact between silane coupling agents and the iron surface, reducing corrosion risks.
- Employ corrosion-resistant materials: In the future design and manufacture of iron drums, consideration can be given to using more corrosion-resistant materials such as stainless steel or aluminum alloys instead of traditional iron materials.
By implementing these measures, the corrosion resistance of iron drums can be effectively improved, their service life extended, and the safe storage and transportation of chemical substances ensured.
