Corrosion nke tinplate nwere ike

A na-akpata mmebi nke ngwaahịa nkwakọ ngwaahịa igwe site na enweghị ike electrochemical nke ihe dị n'ime ihe na-emebi emebi. Ihe ndị bụ isi na-eguzogide corrosion nke tinplate atọ bụ ihe mkpuchi nke tank ahụ, akwa akwa akwa akwa na akwa ígwè, na mkpuchi elu na mkpuchi ala nwere mkpuchi. N'ihi na metal nkwakọ ngwaahịa nwere ụfọdụ shelf ndụ, mgbe tin nwere ike chepụta corrosion ndụ dị ukwuu karịa shelf ndụ nwere ike izute chọrọ nke mmepụta, iji hụ na àgwà na nchekwa nke nri na ihe ọṅụṅụ na shelf ndụ oge, ukwuu corrosion oke bụ ngafe àgwà, dịkwuo aku na uba na-eri nke ngwaahịa.

Ọrụ nnwale ahụ na-egosi na mkpuchi, akwa akwa akwa na akwa ígwè nke tinplate bụ isi ihe mgbochi nchebe corrosion nke tank. Akụrụngwa kwụsiri ike na teknụzụ ezi uche dị na ya nwere ike izute ihe nguzogide corrosion nke ọtụtụ ngwaahịa tankị siri ike. Nchọpụta metụtara na-achọpụtakwa na corrosion na tank nke ụfọdụ ngwaahịa mere na mbụ, n'ihi na dị iche iche nke corrosion na ọnọdụ nke omume, ya mmepe ọnụego dị nnọọ iche, ụfọdụ siri ike tank emepụta nchara tụrụ n'ime a izu ole na ole, oké corrosion ọbụna mgbe a ọnwa ole na ole ga-apụta corrosion perforation phenomenon, ụfọdụ siri ike tank corrosion nwere ike ịnọgide na shelf ndụ mgbe corrosion ga-eme kwa corrosion. Na usoro nke mmepụta na nchekwa nke tinplate Mkpọ, a na-ahụkarị na a ga-enwe tank corrosion tupu eru shelf ndụ nke siri ike Mkpọ, na isi corrosion ụdị na-ekewa n'ime edo corrosion na mpaghara corrosion.

1. Uniform corrosion

Uniform corrosion, nke a makwaara dị ka corrosion zuru oke, a na-ekesa ihe mmebi ahụ n'elu igwe dum, ọnụ ọgụgụ corrosion nke akụkụ nke ọ bụla nke elu ígwè ahụ bụ otu ihe ahụ, n'elu ígwè ahụ na-adịwanye njọ karị, na elu ígwè enweghị ihe dị iche iche na corrosion morphology, corrosion dị otú ahụ dị mfe ịchọta na ịchịkwa n'ihi na ọ na-eme n'elu ihe niile.

2. Mpaghara corrosion

Corrosion mpaghara, nke a na-akpọkwa corrosion na-abụghị nke ụdị, na-akpata site na nguzobe nke batrị mpaghara n'ihi adịghị arụ ọrụ nke electrochemical, dị ka ọla ndị na-adịghị ahụkebe, ntụpọ elu, iche iche nke uche, nchekasị nchekasị ma ọ bụ ọdịdị gburugburu ebe obibi.
