Tsawg Tshaj Tawm Alloy Kovar 4J29 Hlau, 29Hk Hlau rau iav Sealing Alloy Featured Duab

Tsawg Tshaj Kev nthuav dav Alloy Kovar 4J29 Hlau, 29Hk Hlau rau iav Sealing Alloy

Cov lus piav qhia luv luv:

Alloy-4J29 (nthuav dav alloy)
(Lub Npe Lub Npe: Kovar, Nilo K, KV-1, Dilver Poary, Vacon 12)
Alloy-4J29 tseem hu ua Kovar Alloy. Nws tau tsim kom tau raws li qhov xav tau ntawm iav uas muaj kev ntseeg siab, uas yuav tsum muaj nyob rau hauv cov khoom siv hluav taws xob, thiab lub tshuab nqus tsev sab hauv chemistry thiab lwm yam kev tshawb fawb txog kev tshawb fawb. Feem ntau cov hlau tsis tuaj yeem foob rau iav vim tias lawv cov coefficient ntawm cov cua sov tsis yog tib yam li cov kev ntxhov siab tom qab cov iav sib txawv ntawm cov iav thiab hlau ua rau kev sib koom ua ke kom tawg.

Cov FAQ

Khoom Ntawv

Alloy-4J29 tsis tsuas muaj cov khoom nthuav dav zoo ib yam li cov iav, tab sis nws cov kev nkhaus tsis muaj zog tuaj yeem ua rau muaj kev sib koom ua ke los ua ke kom ua siab ntev. Chemically, nws khi rau iav ntawm cov txheej txheem oxide nruab nrab ntawm cov xee npib oxide thiab cobalt ideide; Kev sib npaug ntawm cov hlau oxide yog qhov tsawg vim nws txo qis nrog cobalt. Cov nyiaj txhiv muaj zog yog muaj txiaj ntsig zoo ntawm cov oxide txheej tuab thiab tus cwj pwm. Lub xub ntiag ntawm cobalt ua cov txheej oxide yooj yim kom yaj kom yaj thiab yaj nyob rau hauv lub iav molten. Ib lub xim txho, grey-xiav lossis grey-xim av xim qhia tau lub foob zoo. Cov xim hlau uas qhia tias tsis muaj oxide, thaum xim dub qhia tau cov hlau oxidized ntau, hauv ob qho tib si uas ua rau ib qho tsis muaj zog sib koom ua ke.

Daim Ntawv Thov:Mas siv hauv hluav taws xob nqus cov khoom sib xyaw thiab kev tswj hwm hluav taws xob, lub raj raj ua si, lub raj ntsaws, ua ke, sib xyaw ua ke, nkhaus thiab lwm yam kev sib khi vaj tse.
