Kev Sib Txuas: Kev Siv Tau Ntau Yam thiab Kev Ntsuas Tseeb

 

Txheej Txheem Txheej Txheem:

Cov hlau nplaum neodymium sib txuas yog tsim los ntawm kev siv txoj hauv kev sib txawv uas cuam tshuam nrog kev muab cov khoom sib nqus tso rau hauv cov polymer matrix. Cov txheej txheem suav nrog cov kauj ruam hauv qab no:

 

1. • Kev Tsim Hmoov:Zoo ib yam li cov txheej txheem sintering, neodymium, hlau, thiab boron yog alloyed thiab crushed rau hauv ib tug hmoov zoo.

 

1. • Sib xyaw nrog Polymer:Cov hmoov sib nqus yog sib xyaw nrog cov polymer binder, xws li epoxy lossis yas, los tsim cov khoom sib xyaw ua ke.

 

1. • Kev pwm thiab kev kho:Cov khoom sib tov no raug txhaj tshuaj los yog nias rau hauv cov pwm ntawm ntau yam duab, tom qab ntawd kho lossis tawv kom ua tau lub hlau nplaum kawg.

 

1. • Kev Sib Nqus:Ib yam li cov hlau nplaum sintered, cov hlau nplaum bonded kuj raug magnetized los ntawm kev raug rau lub zog magnetic teb.

 

 

 

Cov txiaj ntsig:

 

• • Cov Duab Sib Txawv:Cov hlau nplaum sib txuas tuaj yeem ua pwm rau hauv cov duab thiab qhov ntau thiab tsawg sib txawv, muab kev ywj pheej tsim qauv ntau dua rau cov engineers.

 

• • Qhov Hnyav Sib Dua:Cov hlau nplaum no feem ntau sib dua li lawv cov sintered counterparts, ua rau lawv zoo tagnrho rau cov ntawv thov qhov twg qhov hnyav yog qhov tseem ceeb.

 

• • Tsis Txhob Nyuaj:Cov polymer matrix muab cov hlau nplaum sib txuas ua ke ntau dua qhov yooj ywm thiab tsawg dua brittleness, txo qhov kev pheej hmoo ntawm chipping lossis tawg.
