What things are acid resistant?

"Acid resistant" is a relative term, as the level of resistance depends on the specific acid, its concentration, and the temperature. However, here are some materials known for their resistance to acids, categorized by their common uses:

μέταλλα:

* ανοξείδωτος χάλυβα: A widely used material, particularly grades like 316L and 304L, which have high resistance to many acids (except concentrated nitric acid).

* Titanium: Highly resistant to many acids, including hydrochloric, sulfuric, and nitric acids. However, it can be attacked by hot concentrated sulfuric acid.

* Tantalum: Extremely resistant to most acids, including hydrochloric, sulfuric, and nitric acids, even at high temperatures.

* Hastelloy: A nickel-based alloy with excellent resistance to various acids, including hydrochloric, sulfuric, and nitric acids.

* Monel: A nickel-copper alloy resistant to many acids, including hydrochloric and sulfuric acids.

Non-Metals:

* γυαλί: Resistant to most acids, except hydrofluoric acid. Special types of glass, like borosilicate glass (Pyrex), have higher resistance to acids.

* κεραμικά: Various types of ceramics offer acid resistance. For example, porcelain and alumina ceramics are used in acid-resistant equipment.

* Πλαστικά: Some plastics like PTFE (Teflon) and PVDF (Polyvinylidene fluoride) are very resistant to acids, but their temperature tolerance can be limited.

Άλλα υλικά:

* καουτσούκ: Certain types of rubber, like nitrile rubber and neoprene, offer resistance to some acids.

* μολύβδου: Lead is used in some applications due to its resistance to sulfuric acid. However, it's not suitable for all acids.

* Concentration and Temperature: The resistance of materials to acids varies greatly depending on the acid concentration and temperature. Higher concentrations and temperatures generally increase the corrosive effect.

* Specific Acid: Each acid has its own set of properties that affect material compatibility.

* Εφαρμογές: Η επιλογή του ανθεκτικού σε οξέα υλικό εξαρτάται από τη συγκεκριμένη εφαρμογή, συμπεριλαμβανομένου του τύπου οξέος, της συγκέντρωσης, της θερμοκρασίας και της προβλεπόμενης χρήσης του υλικού.
