Wolfram filament tungsten waya wowotchera ma waya
Waya wa Tungsten ndi waya wachitsulo wochita bwino kwambiri, womwe nthawi zambiri umapangidwa ndi aloyi ya tungsten. Kapangidwe kake kamakhala ndi waya wapakati ndi zokutira zakunja. Waya wapakati ndi tungsten alloy filament, ndipo zokutira zakunja nthawi zambiri zimakhala zida zapadera za ceramic zomwe zimagwiritsidwa ntchito kuti zithandizire kukana kutentha kwambiri komanso kukana kwa okosijeni. The ndondomeko kupanga tungsten waya kumafuna ntchito limodzi kapena angapo zingwe za tungsten waya wokhotakhota kwa kupanga, ndi kuyendera yachiwiri ikuchitika pa ndondomeko kupanga kuonetsetsa yunifolomu waya awiri, palibe ming'alu mkati, anagawanika, maenje mosalekeza ndi zokopa, etc., kuti akwaniritse zofunika apamwamba.

2. Kampani yathu ili ndi anthu ogwira ntchito zaluso omwe ali ndi zaka zopitilira 15, ndipo timapereka mayankho ndi malingaliro omwe amafunikira kwa kasitomala aliyense.
3. Zogulitsa zathu zonse zimawunikiridwa mosamalitsa musanatumizidwe kunja.
4. Ngati mulandira katundu wolakwika, mungathe kulankhulana nafe kuti mubwezedwe.

9. Chitsimikizo cha khalidwe
Chipangizo chamagetsi
Ntchito: Ntchito semiconductors, vacuum machubu, electron emitters, cathode ray machubu (CRT), etc.
Makhalidwe: Kutsika kwamphamvu komanso kusinthasintha kwa waya wopindika wa tungsten kumapangitsa kuti ikhale chinthu choyenera pazida zamagetsi, zomwe zimatha kuyendetsa bwino pakali pano.
Ng'anjo
Ntchito: Ntchito Kutentha zinthu, thermocouples, mkulu-kutentha masensa, etc.
Mawonekedwe: Kusungunuka kwapamwamba komanso kukana kutentha kwa waya wa tungsten kumathandizira kuti igwire ntchito mokhazikika kwa nthawi yayitali m'ng'anjo zotentha kwambiri komanso kupirira kutentha kwambiri.
Zida zamankhwala
Ntchito: Ntchito X-ray machubu, zipangizo radiotherapy, mankhwala kujambula zipangizo, etc.
Makhalidwe: Malo osungunuka kwambiri komanso kutentha kwapamwamba kwa waya wa tungsten kumapangitsa kuti azigwira ntchito mokhazikika kwa nthawi yayitali pazida zamankhwala, kupereka chithunzithunzi chachipatala cholondola ndi chithandizo.
Kuchuluka kwa waya wopanda yunifolomu wa waya wa tungsten kumatha kutengera zinthu zingapo zokhudzana ndi kupanga ndi zinthu zakuthupi:
1. Njira Yojambulira Waya: Waya wa Tungsten nthawi zambiri amapangidwa kudzera munjira yotchedwa kujambula waya, pomwe ndodo yokulirapo imakokedwa kudzera m'mafa angapo kuti ichepetse kukula kwake. Kusiyanasiyana kwa njira yojambulira mawaya, monga kusagwirizana kosagwirizana, kufa kufa, kapena kusanja kosayenera, kungayambitse kusiyanasiyana kwa waya wa tungsten.
2. Makhalidwe Azinthu: Tungsten ndizovuta kwambiri komanso zowonongeka, zomwe zimapangitsa kuti zikhale zovuta kwambiri kuzikonza. Panthawi yotambasula, ngati zinthuzo sizikutenthedwa mofanana kapena microstructure ya tungsten ndi yosagwirizana, imayambitsa kutambasula kosiyana ndi kusiyana kwake.
3. Kutentha kwamphamvu: Kutentha kwa tungsten kumakhudza ductility yake. Ngati waya wa tungsten watenthedwa mosiyanasiyana panthawi yojambulira, mbali zina zimatha kukhala ductile kuposa zina, zomwe zimapangitsa kuti waya wa tungsten ukhale wosafanana akakoka.
4. Zowonongeka zapamtunda: Kuwonongeka kulikonse kapena kuphatikizidwa mu tungsten kungayambitsenso kusintha kwa m'mimba mwake. Zowonongeka izi zidzayambitsa zolakwika za m'deralo ndikukhudza kujambula kwa waya.
5. Post-processing: Pambuyo pojambula, waya wa tungsten akhoza kuchita zina zowonjezera monga kutsekemera kapena kuyanika. Ngati mankhwalawa ndi osagwirizana, angayambitsenso kusintha kwa m'mimba mwake.
Kuthamanga kwa waya wa tungsten kumachepa chifukwa cha zinthu zingapo:
1. Kutentha Kwambiri: Pamene kutentha kumawonjezeka, mphamvu ya tungsten imawonjezeka. Ichi ndi chodabwitsa chodziwika muzitsulo, kumene kutentha kowonjezereka kumayambitsa kugwedezeka kwa lattice, komwe kumamwaza ma elekitironi ndi kuchepetsa conductivity.
2. Zonyansa: Zonyansa zomwe zimapezeka mu tungsten zimatha kukhudza kwambiri kayendedwe kake. Zonyansa zimasokoneza kamangidwe kazitsulo kazitsulo, kupanga malo omwazika omwe amalepheretsa kuyenda kwa ma electron.
3. Malire a Mbewu: Tungsten nthawi zambiri amasinthidwa kukhala waya pogwiritsa ntchito njira monga kujambula waya ndi kutsekera, zomwe zimatulutsa malire ambewu. Malirewa amatha kukhala ngati zolepheretsa kuyenda kwa ma elekitironi, kuchepetsa conductivity.
4. Kusintha kwamakina: Ngati waya wa tungsten akukumana ndi kupsinjika kwamakina kapena kusinthika, kumayambitsa kusokonezeka ndi zolakwika mu kapangidwe ka kristalo. Zolakwika izi zimabalalitsa ma elekitironi ndikuchepetsa ma conductivity.
5. Oxidation ndi kuipitsidwa kwapamtunda: Tungsten imatulutsa okosijeni ikakumana ndi mpweya kutentha kwambiri, kupanga tungsten oxide pamwamba. Ma oxides awa amatha kukhala ngati ma insulators, amachepetsa kuyendetsa bwino kwa waya.
6. Kusintha kwa gawo: Pazifukwa zina, tungsten idzasintha gawo, zomwe zidzakhudza mphamvu zake zamagetsi. Mwachitsanzo, pa kutentha kwambiri, tungsten ikhoza kusandulika kukhala mawonekedwe a kristalo wosiyana, kusintha kayendedwe kake.
