Silicon nitride ceramic seal bushing

Kufotokozera Kwachidule:

Silicon nitride ili ndi kukana kwamphamvu kwamafuta kuposa zoumba zina. Kuphatikizidwa ndi mphamvu zambiri, kutsika kwamafuta ochepa, kukana kwa dzimbiri komanso kulimba kwa fracture, silicon nitride imagwiritsidwa ntchito nthawi zambiri m'mafakitale apamlengalenga kapena magalimoto. ntchito zina monga nozzles burner, kusungunuka zitsulo processing, etc. Kutchinjiriza magetsi, kukana dzimbiri, sing'anga kutentha kutentha (13000C), ziwiya zadothi structural, katundu makina, otsika matenthedwe kukula, mkulu matenthedwe madutsidwe, zabwino kwambiri matenthedwe bata bata, otsika enieni. mphamvu yokoka.

Silicon nitride ndi ceramic yotuwa yokhala ndi kulimba kwambiri, kukana kutentha kwambiri, komanso zinthu zomwe sizingalowe muzitsulo zosungunuka.

Pogwiritsa ntchito mawonekedwewa, amagwiritsidwa ntchito pazigawo za injini zoyatsira mkati monga zida za injini yamagalimoto, ma nozzles a makina owotcherera a blowpipe, ndi zina, makamaka magawo omwe amayenera kugwiritsidwa ntchito m'malo ovuta monga kutenthedwa.

Ndi kukana kwake kuvala kwambiri komanso mphamvu zamakina apamwamba, kugwiritsa ntchito kwake ponyamula zida zodzigudubuza, mayendedwe ozungulira shaft ndi zida zopangira zida za semiconductor zikukulirakulira nthawi zonse.

Makhalidwe a silicon nitride ceramics

1, ali ndi mphamvu zambiri pamtundu waukulu wa kutentha;

2, mkulu fracture kulimba;

3, mphamvu yopindika yabwino;

4, kukana kutopa makina ndi zokwawa;

5, kuwala - otsika osalimba;

6, kuuma kwakukulu ndi kukana kuvala;

7, kukana kwambiri kutentha kwamphamvu;

8, otsika matenthedwe kukula;

9, insulator yamagetsi;

10, kukana bwino kwa okosijeni;

11, kukana kwa dzimbiri kwa mankhwala.

Ma silicon nitride ceramics ali ndi mphamvu yocheperako yowonjezera kutentha komanso kukhathamiritsa kwamafuta ambiri, motero amakhala ndi kukana kwamphamvu kwa kutentha. Sintered sintered silicon nitride sidzathyoka ikatenthedwa mpaka 1000 ℃ ndikuyika m'madzi ozizira. Pa kutentha kwambiri, silicon nitride imakhala ndi mphamvu zambiri komanso kukana, koma pamwamba pa 1200 ℃ idzawonongeka ndi kukula kwa nthawi yogwiritsira ntchito, kotero kuti mphamvu zake zimachepetsedwa, zowonongeka zowonongeka pamwamba pa 1450 ℃, kotero kugwiritsa ntchito. kutentha kwa Si3N4 nthawi zambiri sikudutsa 1300 ℃.
