Nooca Codsiga La qabsiga iyo Xaqiijinta Qiimaha Carbide Nozzle Scenario

Neefsashada Carbide waa qaybo sax ah oo lagu sameeyay shaandhaynta agabka karbidhida adag (gaar ahaan tungsten carbide, WC) oo leh binders (sida cobalt, Co). Ku faanida adkaanta Vickers ee ka badan 1300 HV, iska caabin aad u fiican (10-20 jeer ka sarreeya birta xawaaraha sare leh), iyo xasilloonida kulaylka xooggan, waxay noqdeen qaybo aasaasi ah oo aan la bedeli karin qaybaha sida warshadaynta, tamarta, iyo elektiroonigga. Furaha lagu kordhinayo qiimahooda codsigu wuxuu ku jiraa la qabsiga nooca saxda ah - oo ku habboon nooca sanbabada saxda ah iyo xaaladaha shaqo ee gaarka ah si loo miisaamo waxqabadka, adkeysiga, iyo waxtarka kharashka.

Xaaladaha farsamaynta jet-ka abrasive, oo ay ku jiraan bacaadka ka saarista miridhku dusha sare iyo jarista jet-biyoodka cadaadiska sare ee taarikada birta, gidaarka gudaha ee birta ah ayaa si isdaba joog ah u saameeya oo u xoqaya xawaaraha sare (ilaa 800 m / s) qaybo abrasive ah (tusaale, alumina, silicon carbide). Taas awgeed, nozzles carbide-garan (oo leh cabbirka hadhuudhka tungsten carbide ee 0.5-1μm) ayaa ah doorashada ugu fiican. Qaab-dhismeedkooda aadka u cufan wuxuu yareeyaa gelitaanka walxaha xoqan, hoos u dhigaya heerka xidhashada gidaarka gudaha si weyn - waxay ku kordhinayaan nolosha adeegga 3-5 jeer marka la barbar dhigo nozzles dhoobada dhaqameed waxayna yareeyaan beddelka joogtada ah.

Xaaladaha heerkulka sare ee warshadaha sida nadiifinta gaaska qiiqa ee birta dhalaalaysa iyo daawaynta qiiqa wasakhda ee gubida, nambarada waa in ay u adkeystaan soo-gaadhista muddada-dheer ee heerkulka sare ee 800-1000 ℃ iyadoo la ilaalinayo xasilloonida socodka hawada. Halkan, tungsten-cobalt carbide nozzles (oo leh 6%-8%) si fiican ayey u qabtaan. Xireeyaha kobalt-ku wuxuu sameeyaa dammaanad xasilloon oo leh miraha carbide tungsten, ka hortagga dildilaaca qaabdhismeedka ay keento shoogga kulaylka iyo hubinta saameynta buufinta joogtada ah, taas oo muhiim u ah nadiifinta gaaska qiiqa si hufan iyo ka saarista boodhka.

Goobaha dareeraha ah ee saxda ah sida nadiifinta chip semiconductor iyo daahan LCD, xitaa qulqulka dareeraha ugu yar wuxuu u horseedi karaa cillado-yar (tusaale, xagashada cabbirka 0.1μm) ee dusha alaabta. Neef-mareenada karbohidratka ee la dafiray-oo leh qallafsanaanta dusha sare ee gidaarka ee Ra≤0.02μm (oo lagu gaadhay shiidida saxda ah ee 12-heer) - waxay meesha ka saaraysaa dareeraha dareeraha ah, awoodna u siinaysa daboolida buufinta lebbiska ah (oo leh weecan wax ka yar 5%) iyo buuxinta shuruudaha saxda ah ee aadka u sarreeya ee warshadaha semiconductor.

Deegaannada macdanta culus ee culus (tusaale, xakamaynta boodhka dhulka hoostiisa ee dhuxusha iyo gaadiidka dhuumaha farsamaynta macdanta), tuubooyinka waxay la kulmaan laba caqabadood: shil farsamo oo ka yimaada jajabyada dhuxusha/dhagaxa iyo daxalka biyaha macdanta leh. Neefsashada carbide ee dhumucda leh (oo leh dhumucdiisuna tahay 5-8mm, 2-3 jeer ka mid ah nozzles caadiga ah) iyo dusha sare ee ka hortagga daxalka (tusaale, chromium plating) ayaa xalliya dhibaatadan. Waxay yareeyaan soo noqnoqda beddelka in ka badan 60% marka la barbar dhigo birta birta ee caadiga ah, hoos u dhigista kharashka dayactirka ee shirkadaha macdanta.

Xaqiijinta qiimaha sanbabada carbide waxay ka imanaysaa is-dhexgalka noocan ah ee qoto dheer. Iyada oo la waafajinayo qaacidooyinka walxaha (tusaale ahaan, hagaajinta nuxurka cobalt), naqshadaha qaab dhismeedka (tusaale, darbiyada dhumucda), iyo farsamaynta saxda ah (tusaale, polishing ultra-fine) baahida warshadaha gaarka ah, kaliya maaha inay hoos u dhigaan kharashaadka dayactirka 30% -50% waxayna hagaajiyaan waxtarka wax soo saarka 20% -30% -taageerada heerka sare ee farsamada Goynta qayb ka mid ah matoorka hawada (oo u baahan nozzles leh saxnaanta cabbirka ± 0.005mm). Maaddaama warshadaha sida tamarta cusub, semiconductor, iyo aerospace ay raacaan heerarka waxqabadka sare, habeynta ku jihaysan muuqaalka ee nozzles-ka carbide waxay sii furi doontaa awooddooda, noqoshada darawal fure u ah cusboonaysiinta warshadaha iyo horumarinta tayada sare leh.
