I-China Low Expansion Alloy Kovar 4j29 Wire, 29HK Ucingo lweGlasi yokutywina i-alloy Manufacture kunye neFactory

Ulwandiso oluPhantsi lwe-alloy ye-Kovar 4j29 ucingo, i-29HK ucingo lwe-Glass yokutywina ingxubevange

Inkcazelo emfutshane:

Ingxubevange-4J29 (Ukwandiswa kwengxubevange)
(Igama eliQhelekileyo: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
I-alloy-4J29 eyaziwa ngokuba yi-alloy ye-Kovar. yayilwa ukuze ihlangabezane nemfuneko yokutywinwa kweglasi ukuya kwintsimbi ethembekileyo, efunekayo kwizixhobo zombane ezinjengeeglowubhu zokukhanyisa, iityhubhu zevacuum, iityhubhu zemitha yecathode, nakwiinkqubo zokufunxa kwikhemistri nolunye uphando lwenzululwazi. Uninzi lwesinyithi alukwazi ukutywina kwiglasi ngenxa yokuba i-coefficient yokwandiswa kwe-thermal ayifani neglasi, njengoko i-joint ipholisa emva kokwenza uxinzelelo ngenxa yokwandiswa kwamazinga eglasi kunye nesinyithi kubangela ukuba umdibaniso uqhekeke.

Iithegi zeMveliso

I-alloy-4J29 ayinayo kuphela ukwanda kwe-thermal efana neglasi, kodwa i-curve yayo yokwandisa i-thermal engapheliyo inokuthi yenziwe ihambelane neglasi, ngaloo ndlela ivumela ukudibanisa ukunyamezela uluhlu olubanzi lokushisa. Ngokwemichiza, ibophelela kwiglasi ngokusebenzisa umaleko ophakathi we-nickel oxide kunye ne-cobalt oxide; umlinganiselo we-iron oxide uphantsi ngenxa yokunciphisa kwayo nge-cobalt. Amandla ebhondi axhomekeke kakhulu kubunzima bomaleko we-oxide kunye nomlinganiswa. Ubukho be-cobalt benza ukuba i-oxide layer ibe lula ukunyibilika kunye nokunyibilika kwiglasi etyhidiweyo. Umbala ongwevu, ongwevu-bhlowu okanye ongwevu-mdaka ubonisa uphawu oluhle. Umbala we-metallic ubonisa ukungabikho kwe-oxide, ngelixa umbala omnyama ubonisa isinyithi esine-oxidized ngokugqithiseleyo, kuzo zombini iimeko ezikhokelela kwilungu elibuthathaka.

Isicelo:Isetyenziswa kakhulu kumacandelo ombane okucoca umbane kunye nolawulo lokukhutshwa, ityhubhu yomothuko, ityhubhu yokutshisa, imagnetron yeglasi, iitransistors, iplagi yokutywina, ukuhanjiswa, ukukhokela kweesekethe ezidibeneyo, i-chassis, izibiyeli kunye nokunye ukutywinwa kwezindlu.
