Which one is more resistant to acids (alkali acids, sulfuric acid), enamel or graphite? And which one is more resistant to alkalis (liquid caustic)? ? It’s best to back up claims with data or regulations. Also, is steel-lined graphite or steel-lined enamel a good choice?
Are you in design? Based on the series of issues mentioned recently, you still lack hands-on experience in the field; it is recommended that you take the opportunity to spend more time on the ground, as this will be very helpful for your design work.
Under normal circumstances, enamel is resistant to acids and alkalis; it is recommended to use enamel as it has a relatively low cost
What concentration of alkali can enamel withstand? At room temperature, does graphite resist alkalis? I’m not in the chemical industry, so I have limited exposure to this area; please forgive me.
I’m sorry; different fields are like separate mountains – no matter how much I explain, you still won’t understand
You had better go and ask on Baidu first; if there are still issues, then you can ask again
Not much is needed; just some basic knowledge dissemination will suffice.
It’s better to check the manuals related to corrosion; I can help you look them up depending on the material and temperature involved
Enameled materials have strong acid resistance; only a few types of acids can corrode them (such as hydrofluoric acid). Graphite has good alkali resistance, but it contains micropores, so it needs to be impregnated with resin. Steel lined with enamel is what is known as glass-lined steel.
Enameled surfaces have poor resistance to alkalis, which can lead to corrosion and the formation of tiny holes on their surface; electrical spark testing can detect conductivity in such areas.
Enameled steel has good acid resistance, but it is already damaged. Avoid sudden changes in temperature. Prevents ceramic cracking. Not resistant to alkalis. Graphite can withstand both acids and alkalis.
