Dub oxide yog txheej txheej hloov dua siab tshiab tsim los ntawm cov tshuaj tiv thaiv uas tsim tawm thaum cov khoom siv rau hauv alkaline aqueous ntsev tov ua haujlwm ntawm kwv yees li 285 degrees F. Cov tshuaj tiv thaiv ntawm cov hlau ntawm ferrous alloy thiab kub. oxide da dej tsim ib tug magnitite (Fe3 O4) ntawm qhov tseeb nto ntawm ib feem.
Ib yam li ntawd, tib neeg nug, dab tsi yog txheej txheem oxide dub?
Dub oxide yog cov txheej txheem hloov dua siab tshiab tsim los ntawm cov tshuaj tiv thaiv uas tsim tawm thaum cov khoom siv rau hauv alkaline aqueous ntsev tov ua haujlwm ntawm kwv yees li 285 degrees F. Cov tshuaj tiv thaiv ntawm cov hlau ntawm ferrous alloy thiab kub. oxide da dej tsim ib tug magnitite (Fe3 O4) ntawm qhov tseeb nto ntawm ib feem.
Ib yam li ntawd, koj siv cov oxide dub li cas? Raus ib feem nyob rau hauv lub mix Dub Oxide Kev daws thiab swirl ib ncig ntawm 30 vib nas this thiab 5 feeb. Tshem tawm ib feem ntawm kev daws thiab yaug hauv dej tshiab. Tam sim ntawd txhuam los yog poob rau hauv Penetrating Sealant, thiab tso cai rau soak hauv cov kua rau 5-10 feeb.
Yog li ntawd, yog dub oxide lom?
Thaum feem ntau cov txheej txheem hlau tiav siv tshuaj lom chemicals, cov dub oxide txheej txheem yog tshwj xeeb phom sij , thiab cov amateurs feem ntau yeej poob siab los ntawm kev sim kub blackening! Ib yam uas ua dub oxiding thiaj li txaus ntshai yog tias cov dub oxide da dej ua haujlwm ntawm li 290 degrees F.
Dab tsi yog dub oxide phom tiav?
Cov dub oxide txheej txheem yog yeej ib daim ntawv ntawm kub bluing nrog molten hydrated ntsev uas tawm hauv lub oxide dub dua xiav. Nws tsim ib tug magnetite ( dub hlau oxide ) ua kom tiav uas yog thinner ntau dua li cov phosphating (Parkerizing) da dej tsim.

Yuav ua li cas tiv thaiv ib tug dwarf dawb los ntawm tsoo mus rau lub qhov dub?
Lub hnub qub dwarf dawb yuav raug tso tseg los ntawm kev tawg txuas ntxiv vim qhov tsis txaus loj uas qhib qhov rooj rau Electron Degeneracy los ua nws txoj haujlwm. Nws yog hu ua Neutron degeneracy siab. Yog li ntawd, lub hnub qub neutron yuav tsis txuas ntxiv mus ua ib lub qhov dub
Yuav ua li cas ua poov tshuaj oxide?
Ntau lawm. Potassium oxide yog tsim los ntawm cov tshuaj tiv thaiv ntawm oxygen thiab potassium; Cov tshuaj tiv thaiv no them rau cov poov tshuaj peroxide, K2O2. Kev kho cov peroxide nrog cov poov tshuaj tsim cov oxide: K2O2 + 2 K → 2 K2O
