Lihlahisoa tse ikhethileng tsa alumina ceramic

Tlhaloso e Khutšoanyane:

Likarolo tsa lisebelisoa tsa tlhahiso ea semiconductor (likarolo tsa cavity, li-flanges tsa insulation, likarolo tsa lisebelisoa tsa etching, wafer chuck); Likarolo tsa Crusher (classifier, leloala la moea, leloala la lifaha); Likarolo tse akaretsang tsa indasteri (li-nozzles tsa mochini o sebetsang oa laser, shafts, libering); Lisebelisoa tsa metallurgic tse phahameng ka ho fetisisa, tse nepahetseng, tse thibelang mocheso (sebopeho sa boemo, kopano ea kopano); Likarolo tse thibang ho roala (rolara ea tataiso ea mochini o takang, kanale ea terata, seporo sa tataiso); Likarolo tse sireletsang motlakase (li-insulators, gaskets, bushings).

Li-tag tsa Sehlahisoa

Alumina ceramicke mofuta oa thepa ea ceramic haholo-holo e entsoeng ka aluminium oxide (AI2O3), e sebelisoang e le thepa e sireletsang lisebelisoa tsa motlakase.Alumina ceramice na le conductivity e ntle, matla a mochine, le ho hanyetsa mocheso o phahameng. Litšobotsi tsa eona li e etsa hore e be e 'ngoe ea lirafshoa tse sebelisoang ka ho fetisisa tikolohong ea meralo, ea moaparo le e senyang.

Li-ceramics tsa aluminium

1. Boima bo phahameng

Rockwell hardness ke HRA80-90, ho thatafala ho tlase ho feta daemane, ho feta khanyetso ea tšepe e sa senyeheng le tšepe e sa hloekang.

2. E babatsehang ho apara ho hanyetsa

E lekantsoe ke litsi tsa lipatlisiso tsa litsebi, ho hanyetsa ha eona ho lekana le linako tse 266 tsa tšepe ea manganese. Gaoming tšepe cast 171.5 linako tse ling, ho ea ka lilemo tse fetang leshome tsa phuputso ea bareki latedisa, tlas'a maemo a tšoanang sebetsa, ka lelefatsa bophelo ba tšebeletso ea thepa bonyane makhetlo a leshome ho feta.

3. Boima bo bobebe

Boima ba eona ba 3.5g / cm3 ke halofo feela ea tšepe, e ka fokotsang thepa haholo.
