Ukuhlolwa kuka-Xinfeng kubonise ukuthi i-cubic centimeter yeI-Sintered NdFeb Magnetingagqwala yi-oxidation ngemva kokuchayeka emoyeni ku-150 ℃ izinsuku ezingu-51.Igqwala kalula ezixazululweni ze-asidi ezibuthakathaka.Ukuze wenze i-NdFeb Permanent Magnet ihlale isikhathi eside, idingeka ukuthi ibe neminyaka engama-20-30 yempilo yesevisi, kufanele ibhekane nokwelashwa kokugqwala kwendawo, ukuze imelane nokugqwala kwendawo edlayo kuMazibuthe.Futhi ngokuvamile ibizwa ngokuthiElectroplating Permanent Magnet.
Njengamanje, umkhakha wokukhiqiza unomphela wesistimu kazibuthe we-NdFeb ngokuvamile wamukela insimbi ye-electroplating, i-electroplating + i-chemical gold-plating, i-electrophoretic coating kanye nokwelashwa kwe-phosphating, njll. i-medium corrosive ihlukanisiwe, ukuze kuvinjwe umonakalo we-medium kuya kuzibuthe.
1.Ngokujwayelekile i-galvanized, i-nickel + ithusi + i-nickel, i-nickel + ithusi + i-nickel engena-electroless plating izinqubo ezintathu, ezinye izidingo ze-metal plating, ngokuvamile ekufakweni kwe-nickel bese kuba nokunye okusetshenziselwa insimbi.
2.Kwezinye izimo ezikhethekile uzosebenzisa i-phosphating
1) Emikhiqizweni kazibuthe ye-NdFeb ngenxa yenzuzo, isikhathi sokulondoloza side kakhulu futhi indlela yokwelapha yokulandelela indawo engacacile, ukusebenzisa i-phosphating kulula futhi kulula;(2) Uma uzibuthe udinga okunamathelayo kwe-epoxy, upende, iglu, upende namanye amandla okuhlanganiswa kwe-epoxy organic kudinga i-substrate ukuthi ibe nokusebenza okuhle kokungena.Inqubo ye-Phosphating ingathuthukisa amandla okungena endaweni kazibuthe.
I-3.I-Electrophoretic coating isiphenduke enye yezindlela ezisetshenziswa kakhulu zokulwa nokugqwala.Ngoba ayinakho nje kuphela ukuthi inamandla okubopha ngobuso bukazibuthe ongenayo, kodwa futhi inokumelana nokugqwala kwesifutho sikasawoti, i-asidi ne-alkali, njll., ukumelana nokugqwala okuhle kakhulu.Kodwa uma kuqhathaniswa nesifutho, ukumelana kwayo nokushisa nomswakama kubi.
Amakhasimende angakhetha enamathela ngokuvumelana nezidingo umsebenzi umkhiqizo wabo.Ngokunwetshwa kwezicelo zezimoto, amakhasimende anezidingo eziphakeme zokumelana nokugqwala kwe-NdFeb, kanyeHigh Quality Electroplating Permanent Magnetiyadingeka.Ukuhlolwa kwe-HAST (ukuhlolwa kwe-PCT) kuklanyelwe ukuhlola ukumelana nokugqwala kozibuthe be-sintered NdFeb ezindaweni ezimanzi nezishisayo.
Amakhasimende anquma kanjani ukuthi i-coating iyahlangabezana nezidingo?Ukuhlolwa kwesifutho sikasawoti kuyinjongo yengaphezulu le-anti-corrosion coating ephathwa nge-sintered NdFeb uzibuthe ukwenza isilingo esisheshayo sokulwa nokugqwala, ekupheleni kokuhlolwa, isampula elisuka ebhokisini lokuhlola, elomile, elinamehlo noma ingilazi yokukhulisa ukuze bheka indawo yesampula enamabala, amabala osayizi webhokisi ashintsha umbala.
Ukufingqa, kuphela ngokuqonda inqubo yokukhiqiza kanye nezidingo zomkhiqizo lapho ikhasimende lingahlulela ngendlela efanele ukuhambisana komkhiqizo.Kafushane nje, wukubamba ukusebenza, ukulawula ukubekezelelana kobukhulu, ukutholwa kokunameka kanye nokuhlolwa kokubukeka.
Mayelana nokusebenza, i-Br(i-residual magnetism), i-Hcb(ukuphoqelela), i-Hcj(i-intrinsic coercivity), (BH) Max (umkhiqizo omkhulu wamandla kazibuthe) kanye nejika lokususa uzibuthe lingatholwa ngokusebenza.Ukubekezelelana Dimensional, ukunemba ingalinganiswa vernier calipers;Ku-coating, umbala nokukhanya kwe-coating kungabonwa ngeso lenyama futhi kutholwe ngokubopha amandla nokuhlolwa kwesifutho sikasawoti.Ukubukeka sekukonke, ikakhulukazi ngeso lenyama noma ngengilazi yokukhulisa, noma isibonakhulu sokubona (komugqa womkhiqizo ongaphansi kuka-0.2mm), ingaphezulu likazibuthe libushelelezi, azikho izinhlayiya ezibonakalayo nemizimba yangaphandle, azinachashazi, azikho i-engeli ewayo enqenqemeni ewayo, ukubukeka kuyafaneleka.
