Asking about materials resistant to bromoacetic acid
Thread Content
As the title suggests, the factory is purchasing filters, and the solvent used for filtration contains bromoacetic acid. After researching relevant information, it seems that 316L and 317L steels are not effective in resisting corrosion caused by bromoacetic acid; titanium material works, but it’s too expensive. So, what other materials exist that can resist corrosion from bromoacetic acid aside from titanium?
For low temperatures, use fluorinated-lined materials; for high temperatures, use enamel-coated ones
When selecting materials resistant to bromoacetic acid, it is indeed necessary to consider the material’s corrosion resistance. In addition to titanium, there are some other materials that can be considered. Here are some suggestions: 1. **Hastelloy**: Hastelloy is a nickel-based corrosion-resistant alloy that exhibits excellent resistance to corrosion caused by acids, alkalis, and redox agents. Among them, Hastelloy C-276 (UNS N10276) and Hastelloy C-22 (UNS N06022) exhibit excellent corrosion resistance in many corrosive environments, and can be considered for use in filters resistant to bromoacetic acid. 2. **Monel alloy**: Monel is a nickel-copper alloy with excellent corrosion resistance. Monel 400 (UNS N04400) and Monel K-500 (UNS N05500) are two common types of Monel alloys that can be considered for use in filters resistant to bromoacetic acid. 3. **Rare earth metals**: Such as zirconium and tantalum, these rare earth metals possess excellent corrosion resistance, but their prices can be high. 4. **Plastics and rubbers**: Certain plastic and rubber materials exhibit good corrosion resistance to bromoacetic acid, such as polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), and fluororubber (Viton). These materials can be chosen as filter materials under certain conditions. It should be noted that when selecting materials, in addition to considering corrosion resistance, other factors such as temperature, pressure, and mechanical properties also need to be taken into account. It is recommended to conduct experiments in practical applications or consult relevant professionals to ensure that the selected materials meet the required specifications. .
