Yuav Ua Li Cas Tom Qab Neodymium Ring Magnets Yog Oxidized

Neodymium nplhaib hlau nplaum, paub txog lawv cov khoom muaj zog sib nqus, tau siv dav hauv ntau yam lag luam, suav nrog hluav taws xob, tsheb, thiab kev kho mob. Txawm li cas los xij, cov hlau nplaum no muaj kev cuam tshuam rau oxidation, ib qho txheej txheem uas tuaj yeem cuam tshuam rau lawv cov kev ua tau zoo thiab kev ua haujlwm ntev.

Thaum neodymium nplhaib hlau nplaum raug rau huab cua, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig ntub, lawv tuaj yeem oxidize. Oxidation ua rau tsim ib txheej ntawm neodymium oxide rau ntawm qhov chaw. Cov txheej no yog nkig thiab tuaj yeem ua rau cov hlau nplaum degrade dhau sijhawm, poob nws lub zog sib nqus. Cov txheej txheem oxidation kuj tuaj yeem ua rau cov txheej txheem tsis muaj zog, ua rau cov hlau nplaum tuaj yeem tawg lossis tawg hauv kev ntxhov siab.

Txhawm rau tiv thaiv oxidation, cov tuam ntxhab feem ntau siv cov txheej txheem tiv thaiv xws li npib tsib xee, zinc, lossis epoxy rau saum npoo ntawm cov hlau nplaum neodymium. Cov coatings no ua ib qho kev thaiv, tiv thaiv kom tsis txhob raug ya raws thiab huab cua, yog li ua kom cov hlau nplaum ruaj khov. Txawm li cas los xij, yog tias cov txheej txheej puas los yog hnav tawm, cov hlau nplaum hauv qab yog rov ua rau oxidation.

Hauv kev xaus, oxidation yog ib qho kev pheej hmoo tseem ceeb rau neodymium nplhaib hlau nplaum, uas yuav txo tau lawv cov kev ua haujlwm thiab kev ua neej. Kev tuav tswj kom raug thiab kev tiv thaiv kev tiv thaiv yog qhov tseem ceeb rau kev tswj xyuas lawv cov kev ua tau zoo.
