How to detect enamel cracking in enamel-coated equipment?
Thread Content
The enamel-lined reaction vessels used in the field can experience enamel cracking during use, and the medium containing hydrochloric acid accelerates this corrosion process. Once cracking occurs, it not only affects the iron ion content of the product but also poses a risk of leakage. Currently, production is carried out batch by batch, and it is possible to filter the residue during discharge; one can determine this by checking whether there are any ceramic shards trapped in the filter screen. But in the future, continuous feeding and discharging production will be adopted; how can any cracks in the porcelain be detected during this process? Please help!~
:(What’s your reaction? Please share your thoughts – what kind of reaction occurs with iron? How does the material change over time? Our enamel-lined reactors are inspected regularly, and it’s generally possible to determine how long they’ve been in use. Moreover, once the color of the material darkens, it usually means that the enamel has started to wear off.)
The material contains hydrochloric acid. We now filter over 100 liters after each batch is produced; if demagnetization occurs, it will definitely be detected. But if it becomes continuous production, with materials coming in and going out continuously, how can this be observed? The material is also not transparent. If the products are substandard, there will be a lot of waste. Or it might simply leak, as hydrochloric acid causes corrosion quite rapidly.
It’s in production; this method can’t be used, right? :L
;P If your material can be sampled regularly for testing purposes regarding iron ions or moisture levels, etc., you can add those as sample parameters. For materials like yours, it’s important to determine which parameters are most sensitive; without any observable reactions, it’s difficult to know what significant changes might occur
Glass splices can be added, but the effect may not be noticeable
Rest assured, intermittent operation, frequent temperature changes, or rough feeding can easily cause the porcelain to crack. By switching to a continuous operation device, the operation is smoother and the temperature remains relatively constant, which makes it less likely for the porcelain to crack. Just be careful whenever starting or stopping the vehicle.
How to determine that it is indeed a problem, how to take samples and how to conduct tests
