The chemical mejupụtara nke nchara Ntụgharị "Tsinkar"
Ihe
Kedu ihe bụ Zinkar mere?
Ngwakọta kemịkalụ nke Tsinkar dịtụ mma maka ụmụ mmadụ, mana n'otu oge ahụ ọ gụnyere ihe ndị na-arụ ọrụ nke na-anagide ebe etiti mbibi ọla. Ọ na-adabere na phosphoric acid dị ọcha site na iji usoro pụrụ iche ma tinye ya na mmiri, nke a na-agbakwunye zinc na manganese ogige.
Otu ihe dị mkpa nke ntụgharị Zinkar nke nchara bụ na ihe mejupụtara nke ngwọta na-agụnye manganese na zinc na ọnọdụ na-emeghachi omume, nke na-emepụta ihe nkiri nchebe nke ike pụrụ iche na elu ígwè. Ndị ọkà mmụta sayensị egosila na ọ bụ ihe ndị na-arụ ọrụ kemịkalụ nke ọgwụ ahụ, na-eme ihe abụọ, na-eme ka o kwe omume iji nweta arụmọrụ dị elu nke Tsinkar - banyere 2-2,7 ugboro dị elu karịa nke ngwọta monophosphate, nke buru ibu na ahịa na ha bụ. dị ọnụ ala, ma ego echekwabara na-ezighị ezi .
Kedu ka ihe ndị mejupụtara nchara nchara Zinkar si arụ ọrụ?
Ọrụ bụ isi nke zinc bụ mmetụta kpọmkwem na etiti electrochemical corrosion, ịmepụta ihe nchebe ígwè. Ihe ọ pụtara bụ na n'okpuru mmetụta nke ikuku ikuku, ihe nchebe na-agbaji, na-eme ka nchekwa nke ihe ndị dị na ígwè dị n'okpuru ya.
Site n'enyemaka nke manganese, a na-ejikọta elu a na-emeso ya, ya bụ, a na-eme ka àgwà nke oyi akwa ahụ dịkwuo mma, nke na-eme ka Zincar dị iche na ogige monophosphate.
Orthophosphoric acid na-eme ka zinc na manganese kwupụta onwe ha n'ụzọ kacha mma. Usoro nke omume ya bụ ịmepụta oyi akwa mkpuchi n'ụdị ihe nkiri phosphate, nke na-eme ka adhesion dịkwuo mma, ya bụ, nchikota nke elu igwe na ihe osise a na-etinye na ya. Ọ bụrụ na agba agba na phosphate emebi emebi, uto nke ebe corrosion na-akwụsị n'ime oke mpaghara ebe e mebiri iguzosi ike n'ezi ihe nke oyi akwa. N'otu oge ahụ, mmetụta nke phosphoric acid na ọnụ ọgụgụ na oxides na-abụghị hydrated na-ebelata.
Tụkwasị na nke ahụ, ngwọta Zincar nwere tannin, yana adsorption na ndị na-emechi emechi. Nke mbụ dị mkpa maka ntughari nke ígwè oxide n'ime ogige ndị na-ekwe ka irighiri nchara na-arapara n'ọkwa molekụla na ibe ha na n'ụdị ígwè na-adịghị emebi emebi. Emebere nke ikpeazụ iji mee ka usoro mmebi ahụ kwụsịlata dị ka o kwere mee, na passivation na-eme site n'enyemaka nke ihe ndị nwere oxidation Njirimara. Igwe nchekwa ahụ, gụnyere ihe ndị na-agafe agafe, na-ebelata ọnụego nke nchara nke ọla. Ụkpụrụ nke ọrụ nke ndị na-eme ihe na-eme ihe na-emepụta ihe bụ ịmepụta ihe nkiri ọzọ na oyi akwa oxide, nke na-eme ka nchebe corrosion dịkwuo elu.
Nsonaazụ nke mmekọrịta nke chemical ọcha
Ngwakọta kemịkalụ nke Tsincar na-enye anyị ohere ikwu maka mgbochi nchara a dị ka otu n'ime ihe ndị na-egbochi corrosion kacha mma n'ihe gbasara arụmọrụ. Ozugbo etinyere ihe ngwọta na oyi akwa metal emetụtara, ihe ndị na-emepụta ngwaahịa ahụ na-amalite ibibi nchara, ebe ụdị oxide nke ígwè na-agbanwe ghọọ phosphate. N'oge usoro a, manganese na-emeghachi omume na zinc. Ha na-eme ka e guzobe oyi akwa nchebe a pụrụ ịdabere na ya nke ihe ndị na-arụ ọrụ.
