Yuav ua li cas Magnet Coatings cuam tshuam rau kev ua haujlwm ntawm U-puab Neodymium Magnets

Cov hlau nplaum neodymium zoo li tus U muaj lub zog sib nqus zoo dua, tab sis lawv kuj ntsib qhov tsis muaj zog tshwj xeeb vim lawv cov qauv geometry thiab qhov tsis zoo ntawm cov khoom neodymium. Thaum lub hlau nplaum tseem ceeb tsim lub zog sib nqus, lub txheej yog nws cov txheej tiv thaiv tseem ceeb, uas txiav txim siab ncaj qha rau nws cov kev ua tau zoo, kev nyab xeeb thiab lub neej ua haujlwm. Kev saib tsis taus qhov kev xaiv txheej tuaj yeem ua rau tsis ua haujlwm ua ntej, txo qis zog lossis tawg txaus ntshai.

Lub Luag Haujlwm Tseem Ceeb ntawm Cov Txheej Txheem
Cov hlau nplaum neodymium xeb sai sai thaum raug dej noo, av noo, ntsev lossis tshuaj lom neeg, ua rau lub zog sib nqus tsis rov qab thiab tawg yooj yim. Lub duab U-puab ua rau cov kev pheej hmoo no hnyav dua: nws lub qhov nkhaus sab hauv ua rau muaj kev ntxhov siab ntawm lub tshuab, nws cov duab geometry txwv tsis pub muaj kuab paug, thiab nws cov kab nkhaus nyuaj rau kev sib npaug ntawm cov txheej txheem. Yog tsis muaj kev tiv thaiv zoo, kev xeb tuaj yeem pib ntawm lub qhov nkhaus sab hauv, ua rau cov zis sib nqus lwj thiab pib tawg uas tuaj yeem ua rau lub hlau nplaum tawg.

Cov txheej txheej ua ntau dua li kev tiv thaiv xeb xwb
Cov txheej txheej zoo ua haujlwm ua ntau yam kev tiv thaiv: lawv tsim ib qho kev thaiv lub cev tiv thaiv kev hem thawj ntawm ib puag ncig, txhim kho kev tiv thaiv kev khawb thiab chipping thaum lub sijhawm tuav, muab kev rwb thaiv hluav taws xob rau cov motors / sensors, thiab tswj kev sib txuas lus hauv qab kev ntxhov siab thermal. Kev npog tob tob yog qhov tseem ceeb rau cov hlau nplaum U-puab - txhua qhov sib txawv yuav ua rau kev ua haujlwm poob qis hauv thaj chaw muaj kev ntxhov siab siab.

Kev Sib Piv ntawm Cov Kev Xaiv Txheej Txheem
Nickel-Tooj Liab-Nickel (Ni-Cu-Ni) plating pheej yig dua thiab muab kev tiv thaiv zoo thiab kev tiv thaiv kev hnav, tab sis muaj kev pheej hmoo ntawm micro-porosity thiab kev npog tsis sib npaug hauv U-bend, yog li nws zoo tshaj plaws rau kev siv sab hauv tsev qhuav.
Cov txheej epoxy zoo heev nyob rau hauv qhov chaw nyuaj - lawv cov txheej tuab dua, kua ntau dua nkag mus tob rau hauv qhov khoov, muab cov dej noo / tshuaj lom neeg zoo heev thiab rwb thaiv hluav taws xob, tab sis lawv txi qee qhov kev tiv thaiv khawb.
Parylene muab cov khoom siv molecular encapsulation zoo kawg nkaus, tsis muaj pinhole txawm tias nyob hauv qhov sib sib zog nqus, ua rau nws zoo tagnrho rau cov xwm txheej hnyav (kev kho mob, aerospace), tab sis nws txoj kev tiv thaiv tshuab yog txwv thiab nws tus nqi siab.
Zinc siv tau ua ib txheej txheem fij rau hauv cov chaw tsis muaj kuab paug uas nws pheej yig, tab sis tsis muaj kev ruaj khov mus sij hawm ntev.
Kub ua kom muaj kev tiv taus xeb thiab kev coj hluav taws xob hauv cov khoom siv hluav taws xob tshwj xeeb, tab sis yuav tsum tau siv ua ke nrog nickel rau kev txhawb nqa cov qauv.

Cov nyhuv ntawm kev xaiv txheej rau kev ua tau zoo
Cov txheej txheej ncaj qha txiav txim siab qhov ruaj khov ntawm lub zog sib nqus - kev xeb tas mus li txo qhov Gauss lub zog thiab lub zog rub. Nws tswj kev ua kom ruaj khov ntawm cov qauv los ntawm kev tiv thaiv cov kab nrib pleb hauv cov khoov sab hauv uas tsis tau txheej. Nws ua kom muaj kev nyab xeeb los ntawm kev tiv thaiv cov khoom tawg uas nyuaj siab. Los ntawm qhov pom ntawm hluav taws xob, cov txheej txheej tiv thaiv cov voj voog luv luv (epoxy / parylene) lossis ua kom muaj kev ntws tam sim no (nickel / kub). Qhov tseem ceeb, cov txheej txheej tsis sib xws ua tsis tiav hauv qhov chaw nyuaj: cov hlau nplaum U-puab nickel-plated tus qauv xeb sai sai hauv qhov chaw ntub dej, thaum cov hlau nplaum tsis muaj rwb thaiv tsev tuaj yeem cuam tshuam nrog cov khoom siv hluav taws xob nyob ze.

Xaiv Cov Txheej Txheem Zoo Tshaj Plaws: Cov Kev Xav Tseem Ceeb
Tsom koj qhov chaw ua haujlwm tseem ceeb: ntsuas qhov av noo, qhov kub thiab txias hloov pauv, kev raug tshuaj lom neeg, thiab kev siv sab hauv tsev/sab nraum zoov. Txheeb xyuas lub neej ua haujlwm uas xav tau - cov xwm txheej hnyav xav tau epoxy lossis parylene coatings. Txheeb xyuas cov kev xav tau hluav taws xob: kev rwb thaiv tsev xav tau epoxy/parylene coatings; conductivity xav tau nickel/kub coatings. Soj ntsuam kev ua haujlwm kho tshuab: nickel coatings tiv taus kev hnav ntau dua li epoxy coatings mos dua. Ib txwm hais txog kev npog sab hauv - cov neeg muag khoom yuav tsum lav qhov sib xws hauv thaj chaw no los ntawm cov txheej txheem tshwj xeeb. Sib npaug cov nqi thiab kev pheej hmoo: Cov kev ntsuas tiv thaiv tsis txaus tuaj yeem ua rau muaj kev ua tsis tiav kim. Rau cov ntawv thov tseem ceeb, yuam kom kuaj ntsev tsuag.

Siv cov kev coj ua zoo tshaj plaws
Qhia meej txog hom txheej thiab qhov tuab tsawg kawg nkaus hauv cov lus qhia tshwj xeeb (piv txwv li, "30μm epoxy"). Yuav tsum tau cov chaw tsim khoom muab cov pov thawj sau ntawv ntawm kev npog inbend. Ua haujlwm nrog cov kws tshaj lij uas muaj kev paub txog U-puab magnet geometries - lawv cov txheej txheem txheej txheem tau calibrated rau cov duab nyuaj. Sim cov qauv prototypes nyob rau hauv lub ntiaj teb tiag tiag ua ntej tag nrho cov khoom tsim tawm; tso rau lawv rau qhov kub thiab txias, tshuaj lom neeg, lossis av noo kom paub tseeb tias ua tau zoo.

Xaus Lus: Cov Txheej Txheem Ua Tus Saib Xyuas Zoo
Rau cov hlau nplaum neodymium zoo li tus U, cov txheej txheej tsis yog kev kho saum npoo, tab sis yog cov kev tiv thaiv tseem ceeb rau kev ntseeg tau. Kev xaiv cov txheej txheej epoxy rau cov chaw ntub dej, cov txheej txheej parylene rau kev phais mob kom raug, lossis cov txheej txheej plating rau kev coj ua hluav taws xob tuaj yeem hloov pauv qhov tsis yooj yim mus rau hauv kev tawv. Los ntawm kev sib phim kev ua tau zoo ntawm cov txheej txheem rau cov kev xav tau ntawm daim ntawv thov thiab txheeb xyuas kev tiv thaiv ntawm qhov tseem ceeb, koj tuaj yeem ua kom muaj kev ua tau zoo ntawm cov hlau nplaum rau ntau xyoo caum. Tsis txhob cuam tshuam rau kev tiv thaiv txheej: koj lub zog hlau nplaum nyob ntawm nws.
