dhoobada Silicon nitride oo leh sifooyin jidheed oo aad u wanaagsan, kiimiko iyo farsamo
Ceramics Silicon nitride waxay leedahay faa'iidooyin aad u wanaagsan: cufnaanta hoose, iska caabinta heerkulka sare, saliidda is-dheellida, iska caabinta daxalka. Cufan Si3N4dhoobada sidoo kale waxay soo bandhigtaa adkaanshaha sare ee jabka, sifooyinka modules-ka sare iyo dufanka nafsiga ah, taas oo noqon karta iska caabin heer sare ah oo xirmo kala duwan leh oo u adkeysan kara jawi adag oo keeni kara in alaabta kale ee dhoobada ay dillaacaan, qallafsanto ama burburto, oo ay ku jiraan heerkul aad u sarreeya, kala duwanaansho heerkul weyn. iyo vacuum ultra-high.
Codsiyada Muhiimka ah ee Ceramics Silicon Nitride
Farsamada farsamada: Ceramics Silicon nitride waxay leeyihiin engegnaan sare, caabbinta xidhashada aad u fiican iyo iska caabinta daxalka, waxaana si weyn loogu adeegsadaa goobaha injineernimada. Waxaa loo isticmaali karaa in lagu soo saaro qaybo ay ka mid yihiin xirmooyinka, shaabadda, qalabka wax lagu gooyo iyo sanbabada heerkulka sare iyo xawaaraha, bixinta waxqabad aad u fiican iyo nolol dheer.
Warshadaha baabuurta: Sababtoo ah xasilloonida heerkulka sare iyo xirashada caabbinta ceramics silicon nitride, waxaa loo isticmaalaa soo saarista qaybaha matoorada baabuurta. Silicon nitride ceramics waxaa loo isticmaali karaa in lagu sameeyo qaybo engine ah oo wax qabad sare leh sida giraanta piston, liners cylinder iyo valves, caawinta hagaajinta waxtarka shidaalka iyo yaraynta qiiqa.
Hawada hawada: Miisaanka fudud, xoogga sare iyo iska caabbinta heerkulka sare ee ceramics silicon nitride ayaa ka dhigaya agab ku habboon codsiyada hawada sare. Waxaa loo isticmaali karaa in lagu soo saaro qaybaha muhiimka ah sida qaybaha mishiinka, marawaxadaha marawaxadaha, qalabka go'doominta kulaylka iyo ilaalinta kulaylka hawada sare si loo buuxiyo shuruudaha heerkulka sare, cadaadiska sare iyo jawiga daran.
Warshadaha kiimikada: Ceramics Silicon nitride ayaa si weyn loogu isticmaalaa warshadaha kiimikada sababtoo ah xasiloonidooda kiimikada ee aadka u wanaagsan iyo iska caabinta daxalka. ceramics Silicon nitride waxaa loo isticmaali karaa in lagu soo saaro weelasha falcelinta kiimikaad, qaadeyaasha kicinta, aashitada iyo qalabka alkali u adkaysta iyo tuubooyinka, waxayna u adkeysan kartaa warbaahinta daxalka ah iyo xaaladaha heerkulka sare.
Optoelectronics: Silicon nitride ceramics waxay leeyihiin sifooyin muuqaal iyo elektaroonig ah oo aad u fiican, sidaa darteed waxay leeyihiin codsiyo muhiim ah oo ku saabsan optoelectronics. Waxaa loo isticmaali karaa in lagu soo saaro heerkul sare iyo awood sare oo fibre amplifiers, leysarka, qalabka isgaarsiinta indhaha iyo Windows indhaha ... iwm, oo leh gudbinta indhaha oo aad u fiican iyo xasilloonida kulaylka.
