Low Expansion Alloy Kovar 4j29 Waya, 29HK Waya wa Glass Sealing Alloy

Kufotokozera Kwachidule:

Aloyi-4J29 (Aloyi yowonjezera)
(Common Name: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
Aloyi-4J29 amadziwikanso kuti Kovar alloy.linapangidwa kuti likwaniritse kufunika kwa chosindikizira chodalirika cha galasi ndi chitsulo, chomwe chimafunika pa zipangizo zamagetsi monga mababu a magetsi, machubu otsekemera, machubu a cathode ray, ndi makina otsekemera mu chemistry ndi kafukufuku wina wa sayansi.Zitsulo zambiri sizingathe kusindikiza ku galasi chifukwa mphamvu yake yowonjezera kutentha sikufanana ndi galasi, kotero kuti cholowacho chimazizira pambuyo popanga kupanikizika chifukwa cha kusiyana kwa magalasi ndi zitsulo zomwe zimapangitsa kuti mgwirizanowo ukhale wosweka.

    Alloy-4J29 sikuti amangokhala ndi kufalikira kwa kutentha kofanana ndi galasi, koma mawonekedwe ake osagwirizana ndi kutentha kwa kutentha amatha kupangidwa kuti agwirizane ndi galasi, motero amalola kuti mgwirizanowo ukhale wotentha kwambiri.Mwachindunji, imamangiriza ku galasi kudzera muzitsulo zapakatikati za nickel oxide ndi cobalt oxide;gawo la chitsulo okusayidi ndilotsika chifukwa cha kuchepa kwake ndi cobalt.Mphamvu ya mgwirizano imadalira kwambiri makulidwe a oxide wosanjikiza ndi mawonekedwe.Kukhalapo kwa cobalt kumapangitsa kuti oxide wosanjikiza ikhale yosavuta kusungunuka ndi kusungunuka mu galasi losungunuka.Mtundu wa imvi, imvi-buluu kapena imvi-bulauni umasonyeza chisindikizo chabwino.Mtundu wachitsulo umasonyeza kusowa kwa okusayidi, pamene mtundu wakuda umasonyeza chitsulo chochuluka kwambiri cha okosijeni, nthawi zonse zomwe zimatsogolera ku mgwirizano wofooka.

    Ntchito:Amagwiritsidwa ntchito kwambiri pazigawo za vacuum yamagetsi ndi kuwongolera kutulutsa, chubu chodzidzimutsa, chubu choyatsira, maginito agalasi, ma transistors, pulagi yosindikizira, ma relay, kutsogolera mabwalo ophatikizika, chassis, bulaketi ndi kusindikiza kwina kwanyumba.
