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

I-Alloy Yokukhulisa Okuphansi I-Kovar 4j29 Wire, I-29HK Wire ye-Alloy Yokuvala Ingilazi

Incazelo emfushane:

I-Alloy-4J29 (I-alloy yokwandisa)
(Igama Elijwayelekile: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
I-Alloy-4J29 eyaziwa nangokuthi i-Kovar alloy. Yasungulwa ukuze ihlangabezane nesidingo sokuvala okuthembekile kwengilazi kuya kwensimbi, okudingekayo kumadivayisi kagesi afana nama-light bulbs, ama-vacuum tubes, ama-cathode ray tubes, kanye nasezinhlelweni ze-vacuum kumakhemikhali nakwezinye ucwaningo lwesayensi. Izinsimbi eziningi azikwazi ukuvala ingilazi ngoba i-coefficient yazo yokwandisa ukushisa ayifani nengilazi, ngakho-ke njengoba i-joint iphola ngemva kokwenziwa, ukucindezeleka okubangelwa amazinga okukhulisa ahlukene engilazi nensimbi kubangela ukuthi i-joint iqhekeke.

Imibuzo Evame Ukubuzwa

Amathegi Omkhiqizo

I-Alloy-4J29 ayigcini nje ngokuba nokwanda kokushisa okufana nengilazi, kodwa ijika layo lokukhula kokushisa elingaqondile lingenziwa lifane nengilazi, ngaleyo ndlela livumele ijoyinti ukuthi libekezelele izinga lokushisa elibanzi. Ngokwekhemikhali, ibophana nengilazi ngengqimba ye-oxide ephakathi ye-nickel oxide ne-cobalt oxide; isilinganiso se-iron oxide siphansi ngenxa yokuncipha kwayo ne-cobalt. Amandla ebhondi ancike kakhulu ekujiyeni kanye nohlamvu lwengqimba ye-oxide. Ukuba khona kwe-cobalt kwenza ingqimba ye-oxide ibe lula ukuyincibilikisa nokuyincibilikisa engilazini encibilikisiwe. Umbala ompunga, ompunga-oluhlaza okwesibhakabhaka noma onsundu ompunga ubonisa uphawu oluhle. Umbala wensimbi ubonisa ukuntuleka kwe-oxide, kanti umbala omnyama ubonisa insimbi e-oxidized ngokweqile, kuzo zombili izimo okuholela ekuhlanganeni okubuthakathaka.

Isicelo:Isetshenziswa kakhulu ezingxenyeni ze-vacuum kagesi kanye nokulawula ukukhishwa komoya, i-shock tube, i-igniting tube, i-glass magnetron, ama-transistors, i-seal plug, i-relay, i-integrated circuits lead, i-chassis, ama-bracket kanye nokunye ukuvalwa kwezindlu.
