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

I-Low Expansion Alloy Kovar 4j29 Wire, 29HK Wire ye-Glass Sealing Alloy

Incazelo emfushane:

I-alloy-4J29 (Ingxubevange yokwandisa)
(Igama Elijwayelekile: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
Ingxubevange-4J29 eyaziwa nangokuthi Kovar ingxubevange.yasungulwa ukuze kuhlangatshezwane nesidingo sophawu oluthembekile lwengilazi-kuya-metal, oludingekayo ezintweni zikagesi ezifana nezibani, amashubhu e-vacuum, amashubhu e-cathode ray, nasezimisweni ze-vacuum kukhemistri nolunye ucwaningo lwesayensi.Izinsimbi eziningi azikwazi ukuvala ingilazi ngenxa yokuthi i-coefficient yazo yokwanda okushisayo ayifani nengilazi, ngakho-ke njengoba ilunga liphola ngemva kokwenza izingcindezi ngenxa yokuhluka kwamazinga okunwetshwa kwengilazi nensimbi kubangela ukuthi ilunga liqhekeke.

FAQ

Omaka bomkhiqizo

I-alloy-4J29 ayinakho nje ukunwetshwa okushisayo okufana nengilazi, kodwa ijika layo lokunweba elishisayo elingavamile ngokuvamile lingenziwa ukuze lifane nengilazi, ngaleyo ndlela livumele ukujoyina ukubekezelela ububanzi obubanzi bokushisa.Ngokwekhemikhali, ibophela engilazini ngongqimba lwe-oxide olumaphakathi lwe-nickel oxide ne-cobalt oxide;ingxenye ye-iron oxide iphansi ngenxa yokuncipha kwayo nge-cobalt.Amandla ebhondi ancike kakhulu kugqinsi lwesendlalelo se-oxide nohlamvu.Ukuba khona kwe-cobalt kwenza ungqimba lwe-oxide lube lula ukuncibilika nokuncibilika engilazini encibilikisiwe.Umbala ompunga, ompunga-oluhlaza okwesibhakabhaka noma ompunga-nsundu ukhombisa uphawu oluhle.Umbala we-metallic ubonisa ukuntuleka kwe-oxide, kuyilapho umbala omnyama ubonisa insimbi ene-oxidized ngokweqile, kuzo zombili izimo okuholela ekuhlanganyeleni okubuthakathaka.

Isicelo:Isetshenziswa kakhulu ezingxenyeni ze-vacuum kagesi kanye nokulawulwa kokukhipha, ishubhu lokushaqeka, ishubhu lomlilo, i-magnetron yengilazi, ama-transistors, ipulaki yophawu, i-relay, i-lead circuits lead, chassis, abakaki nokunye ukuvalwa kwezindlu.
