Tuam Tshoj Qis Tshaj Plaws Alloy Kovar 4j29 Hlau, 29HK Hlau rau Iav Sealing Alloy Tsim thiab Hoobkas

Cov Hlau Uas Tsis Tshua Muaj Kev Nthuav Dav Kovar 4j29 Hlau, 29HK Hlau Rau Iav Sealing Alloy

Kev Piav Qhia Luv:

Cov hlau nplaum-4J29 (Cov hlau nplaum nthuav dav)
(Common Name: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
Alloy-4J29 tseem hu ua Kovar alloy. nws tau tsim los ua kom tau raws li qhov xav tau rau lub foob iav-rau-hlau txhim khu kev qha, uas yog qhov xav tau hauv cov khoom siv hluav taws xob xws li lub teeb, cov raj nqus tsev, cov raj cathode ray, thiab hauv cov tshuab nqus tsev hauv chemistry thiab lwm yam kev tshawb fawb. Feem ntau cov hlau tsis tuaj yeem kaw rau iav vim tias lawv cov coefficient ntawm thermal expansion tsis zoo ib yam li iav, yog li thaum qhov sib koom ua ke txias tom qab tsim cov kev ntxhov siab vim qhov sib txawv ntawm cov iav thiab hlau ua rau qhov sib koom ua ke tawg.

Cov Lus Qhia Txog Khoom

Cov Lus Nug Feem Ntau

Cov Cim Npe Khoom

Alloy-4J29 tsis yog tsuas muaj kev nthuav dav thermal zoo ib yam li iav xwb, tab sis nws cov kab nkhaus nthuav dav thermal nonlinear feem ntau tuaj yeem ua kom phim iav, yog li tso cai rau qhov sib koom ua ke kom zam tau qhov kub thiab txias ntau. Chemically, nws khi rau iav ntawm cov txheej oxide nruab nrab ntawm nickel oxide thiab cobalt oxide; qhov feem pua ntawm hlau oxide qis vim nws txo qis nrog cobalt. Lub zog sib koom ua ke yog nyob ntawm qhov tuab thiab tus cwj pwm ntawm cov txheej oxide. Qhov muaj cobalt ua rau cov txheej oxide yooj yim yaj thiab yaj hauv cov iav yaj. Xim grey, grey-xiav lossis grey-xim av qhia txog kev foob zoo. Xim hlau qhia txog tsis muaj oxide, thaum xim dub qhia txog hlau oxidized ntau dhau, hauv ob qho tib si ua rau qhov sib koom ua ke tsis muaj zog.

Daim Ntawv Thov:Feem ntau siv rau hauv cov khoom siv hluav taws xob thiab kev tswj hwm pa phem, lub raj xa hluav taws xob poob siab, lub raj xa hluav taws xob, iav magnetron, transistors, lub ntsaws foob, relay, cov hlau lead hauv kev sib xyaw ua ke, chassis, cov brackets thiab lwm yam kev sib khi hauv tsev.
