I-China Low Expansion Alloy Kovar 4j29 Wire, 29HK Wire for Glass Sealing Alloy manufacture and Factory

I-Alloy Yokwandisa Okuphantsi I-Kovar 4j29 Wire, I-29HK Wire ye-Glass Sealing Alloy Umfanekiso Obonakalayo

I-Alloy Yokwandisa Ephantsi ye-Kovar 4j29 Wire, i-29HK Wire ye-Alloy Yokuvala Iglasi

Inkcazo emfutshane:

I-Alloy-4J29 (i-alloy yokwandisa)
(Igama eliQhelekileyo: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
I-Alloy-4J29 ekwaziwa ngokuba yi-Kovar alloy. Yenzelwe ukuhlangabezana nesidingo sesitywini esithembekileyo seglasi ukuya kwisinyithi, esifunekayo kwizixhobo ze-elektroniki ezifana neebhalbhu zokukhanya, iityhubhu ze-vacuum, iityhubhu ze-cathode ray, nakwiinkqubo ze-vacuum kwikhemistri nakwezinye uphando lwesayensi. Uninzi lweentsimbi alunakuyitywina iglasi kuba i-coefficient yazo yokwandisa ubushushu ayifani neglasi, ngoko ke njengoko ijoyinti iphola emva kokwenziwa, uxinzelelo olubangelwa ngamazinga okwanda okwahlukileyo kweglasi kunye nesinyithi lubangela ukuba ijoyinti iqhekeke.

I-Alloy-4J29 ayinayo nje kuphela i-thermal expansion efana neglasi, kodwa i-nonlinear thermal expansion curve yayo inokwenziwa ukuba ifane neglasi, ngaloo ndlela ivumela i-joint ukuba inyamezele ubushushu obubanzi. Ngokwekhemikhali, inamathela kwiglasi ngokusebenzisa i-intermediate oxide layer ye-nickel oxide kunye ne-cobalt oxide; umlinganiselo we-iron oxide uphantsi ngenxa yokuncipha kwayo nge-cobalt. Amandla e-bond axhomekeke kakhulu kubukhulu kunye nophawu lwe-oxide layer. Ubukho be-cobalt benza kube lula ukunyibilika nokunyibilika kwe-oxide layer kwiglasi enyibilikisiweyo. Umbala ongwevu, ongwevu-oluhlaza okwesibhakabhaka okanye ongwevu-omdaka ubonisa uphawu oluhle. Umbala wesinyithi ubonisa ukungabikho kwe-oxide, ngelixa umbala omnyama ubonisa isinyithi esixineneyo kakhulu, kuzo zombini iimeko ezikhokelela kwi-joint ebuthathaka.

Isicelo:Isetyenziswa kakhulu kwizixhobo zombane zokucoca umoya kunye nolawulo lokukhupha umoya, ityhubhu yokutsha, ityhubhu yokutsha, imagnetron yeglasi, iitransistors, iplagi yesitywina, irelay, i-lead yeesekethe ezidibeneyo, i-chassis, iibrakethi kunye nezinye izitywina zezindlu.
