Dị ka anyị maara, n'etiti efere efere nke okpomọkụ Exchanger, titanium efere pụrụ iche n'ihi na ya magburu onwe iguzogide corrosion.Na na nhọrọ nke gasket, viton gasket bụ ama maka iguzogide acid na alkali na kemịkalụ ndị ọzọ.Ya mere enwere ike iji ha ọnụ mee ka nguzogide corrosion nke efere ọkụ na-agbanwe?
N'ezie, Titanium efere na viton gasket enweghị ike iji ọnụ.Mana gịnị mere?Ọ bụ ụkpụrụ na-eguzogide corrosion nke titanium efere na ihe abụọ ahụ enweghị ike ijikọ ọnụ, n'ihi na efere titanium dị mfe ịmepụta oyi akwa nke ihe nkiri nchebe nke titanium oxide n'elu, nke a nwere ike ịmepụta ihe nkiri oxide ngwa ngwa na oxygen- nwere gburugburu ebe obibi mgbe mbibi.Na nke a na-enye ohere ka mbibi na nrụzi (repassivation) nke ihe nkiri oxide na-echekwa na steeti kwụsiri ike, na-echebe ihe ndị titanium dị n'ime na-emepụta mbibi ọzọ.
Foto corrosion a na-ahụkarị
Otú ọ dị, mgbe titanium metal ma ọ bụ alloy na gburugburu ebe fluorine nwere fluorine, n'okpuru omume nke hydrogen ion na mmiri, fluoride ions si na viton gasket na-emeghachi omume na metal titanium na-emepụta fluoride soluble, nke na-eme ka titanium pitting.Nhazi mmeghachi omume bụ nke a:
Ti2O3+ 6HF = 2TiF3+ 3H2O
TiO2+ 4HF = TiF4+ 2H2O
TiO2+ 2HF = TiOF2+ H2O
Nnyocha achọpụtala na na ngwọta acidic, mgbe ntinye fluoride ion ruru 30ppm, enwere ike ibibi ihe nkiri oxidation na elu titanium, na-egosi na ọbụlagodi ma ọ bụrụ na ion fluoride dị ntakịrị ga-ebelata nrụrụ nke efere titanium.
Mgbe ígwè titanium na-enweghị nchebe nke titanium oxide, na gburugburu ebe obibi na-emebi emebi nwere hydrogen nke evolushọn hydrogen, titanium ga-anọgide na-amịkọrọ hydrogen, mmeghachi omume REDOX na-eme.Mgbe ahụ, a na-emepụta TiH2 n'elu kristal titanium, nke na-eme ka mmebi nke efere titanium dị ngwa ngwa, na-eme ka ọkpụkpụ na-eduga na nkwụsị nke ihe na-ekpo ọkụ ọkụ.
Ya mere, na ihe na-ekpo ọkụ na-ekpo ọkụ na efere, titanium plate na viton gasket agaghị ejikọ ọnụ, ma ọ bụghị ya, ọ ga-eduga na corrosion na ọdịda nke ihe na-ekpo ọkụ efere.
Shanghai Heat Nyefee Equipment Co., Ltd (SHPHE) nwere ọgaranya ọrụ ahụmahụ na efere okpomọkụ Exchanger ụlọ ọrụ, na nwekwara metụtara anụ ahụ na chemical laboratories, nke nwere ike ngwa ngwa na n'ụzọ ziri ezi ikpebi ihe efere na gasket maka ndị ahịa na mmalite ogbo nke. nhọrọ, iji hụ na arụ ọrụ akụrụngwa dị mma na ntụkwasị obi.
