chidziwitso

The zodabwitsa katundu wa zithunzi za tantalum zawapanga kukhala zinthu zochulukirachulukira m'mafakitale osiyanasiyana, kuyambira zamagetsi mpaka zida zamankhwala. Tantalum ndi chitsulo chosowa, cholimba, chotuwa chabuluu, chonyezimira chomwe chimadziwika chifukwa cha kusachita bwino kwa dzimbiri, malo osungunuka kwambiri, komanso kuthekera kopanga zinthu zokhazikika. Ikapangidwa kukhala ma diski, tantalum imawonetsa mawonekedwe apadera akuthupi ndi makemikolo omwe amapangitsa kuti ikhale yamtengo wapatali pamapulogalamu ambiri.

Kodi Zofunika Zazikulu za Tantalum Discs ndi ziti?

Ma disc a Tantalum ndi amtengo wapatali chifukwa cha mawonekedwe ake odabwitsa. Chimodzi mwazinthu zodziwika bwino ndi mphamvu zawo zosaneneka komanso kulimba. Tantalum ndi chitsulo cholimba kwambiri, chomwe chili pa 6.5-7 pa sikelo ya Mohs hardness, zomwe zimapangitsa kuti zisawonongeke kukwapula, mano, ndi kuwonongeka kwa makina. Kulimba kumeneku, kuphatikizidwa ndi malo ake osungunuka opitilira 3,000 ° C, kumapangitsa ma tantalum kukhazikika komanso kukhala ndi moyo wautali, ngakhale m'malo ovuta.

Chinthu chinanso chofunika kwambiri cha ma tantalum discs ndi gawo lawo lochepa la kukula kwa kutentha. Izi zikutanthauza kuti zinthuzo zimakana kusintha kwa kukula ndi mawonekedwe zikakumana ndi kusinthasintha kwa kutentha, zomwe zimapangitsa kukhala chisankho chabwino pamapulogalamu omwe amafunikira kukhazikika kwa mawonekedwe, monga zida zolondola ndi zida.

Ma disks a Tantalum amawonetsanso zinthu zabwino kwambiri zamagetsi, kuphatikiza madutsidwe amagetsi apamwamba komanso kutsika kwa dielectric. Makhalidwewa amawapangitsa kukhala oyenerera kuti agwiritsidwe ntchito pazinthu zamagetsi, monga capacitors ndi resistors, kumene kuthekera kwawo kusunga ndi kutumiza zizindikiro zamagetsi ndi kusokoneza kochepa kumayamikiridwa kwambiri.

Chimodzi mwa zinthu zochititsa chidwi kwambiri za tantalum discs, komabe, ndi kukana kwawo kodabwitsa kwa dzimbiri. Tantalum imapanga wosanjikiza wopyapyala wa oxide pamwamba pake womwe umateteza chitsulo chochokera kuzinthu zambiri zowononga, kuphatikiza ma acid, maziko, ndi ma organic compounds osiyanasiyana. Kukana kwa dzimbiri kumeneku kumapangitsa ma tantalum kukhala chisankho choyenera kuti chigwiritsidwe ntchito m'malo ovuta, owononga, monga zida zopangira mankhwala, zoyikapo zachipatala, ndi kugwiritsa ntchito zakuthambo.

Nchiyani Chimapangitsa Tantalum Diss Kuti Isakhale ndi Corrosion?

Kulimbana ndi dzimbiri zithunzi za tantalum makamaka chifukwa cha mapangidwe osanjikiza okusayidi pamwamba pa zitsulo. Tantalum ikakhala ndi okosijeni kapena zinthu zina zotulutsa okosijeni, imapanga kagawo kakang'ono kakang'ono ka tantalum pentoxide (Ta2O5) komwe kumateteza chitsulo kuti chisayambe dzimbiri.

Kusanjikiza kwa okusayidi kumeneku kumakhala kokhazikika komanso kosagwirizana ndi kuukira kwamankhwala, ngakhale pakakhala ma asidi amphamvu ndi maziko. Chosanjikizacho chimakhalanso chodzichiritsa, kutanthauza kuti ngati chawonongeka kapena kusokonezedwa, tantalum idzapanga msanga wosanjikiza watsopano wa oxide kuti abwezeretse chotchinga choteteza.

Kukana kwa dzimbiri kwapadera kwa ma tantalum discs kumakulitsidwanso ndi kutsika kwa zinthuzo. Tantalum imatengedwa kuti ndi imodzi mwazitsulo zomwe zimakhala ndi mankhwala, zomwe zimakhala zochepa kwambiri kupanga mankhwala kapena kuchita ndi zinthu zina. Izi zimapangitsa kuti zisagwirizane kwambiri ndi zinthu zambiri zowononga, kuphatikizapo ma acid ambiri, alkalis, ndi oxidizing agents.

Kuphatikiza pa mawonekedwe osanjikiza a oxide ndi otsika reactivity, wandiweyani komanso wofananira wa ma tantalum discs nawonso amathandizira kukana dzimbiri. Kusapezeka kwa malire a tirigu ndi zolakwika zina za microstructural muzinthu zimapangitsa kuti zisawonongeke ndi dzimbiri zamtundu wina, monga pitting kapena corrosion, yomwe imatha kuchitika muzitsulo zina.

Kuphatikizika kwa zinthu izi - wosanjikiza wa oxide passive, low reactivity, ndi wandiweyani, mawonekedwe ofanana - zimapangitsa ma tantalum discs kukhala zinthu zosagwira dzimbiri, zomwe zimatha kupirira ngakhale malo ovuta kwambiri.

Kodi Ma Disc a Tantalum Amagwiritsidwa Ntchito Bwanji Paukadaulo?

Ma disks a Tantalum ali ndi ntchito zosiyanasiyana m'mafakitale osiyanasiyana chifukwa cha mawonekedwe awo apadera akuthupi ndi mankhwala. Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi ma tantalum discs ndi mafakitale amagetsi, komwe amagwiritsidwa ntchito ngati ma capacitors.

Ma capacitor a Tantalum amadziwika ndi kuthekera kwawo kwakukulu, kukula kochepa, komanso kudalirika kwambiri, zomwe zimawapangitsa kukhala abwino kugwiritsa ntchito zida zosiyanasiyana zamagetsi, monga mafoni am'manja, laputopu, ndi zamagetsi zamagalimoto. Kuthamanga kwamagetsi kwapamwamba komanso kutsika kwa dielectric kosasintha kwa tantalum discs kumapangitsa kuti pakhale ma capacitor ophatikizika, apamwamba kwambiri omwe amatha kusunga ndikutulutsa mphamvu zamagetsi moyenera.

Ntchito ina yofunika ya tantalum discs ndi m'makampani azachipatala. Chifukwa cha kukana kwawo kwa dzimbiri komanso kuyanjana ndi biocompatibility, ma tantalum discs amagwiritsidwa ntchito kwambiri popanga implants zachipatala, monga zolowa m'malo mwa mafupa, zoyika mano, ndi zida za mtima pacemaker. Chikhalidwe cha inert cha tantalum chimathandiza kupewa kutulutsidwa kwa ayoni kapena mankhwala owopsa m'thupi, ndikupangitsa kuti ikhale yotetezeka komanso yolimba pakugwiritsa ntchito izi.

Ma disks a Tantalum amagwiritsidwanso ntchito m'mafakitale osiyanasiyana, kuphatikiza zida zopangira mankhwala, monga mavavu, mapampu, ndi zosinthira kutentha. Kukaniza kwa dzimbiri kwa tantalum kumalola zigawozi kuti zipirire kukhudzana ndi mitundu yambiri yamankhwala ankhanza, kuwapanga kukhala zinthu zofunika kwambiri pamakampani opanga mankhwala.

M'makampani azamlengalenga, ma disc a tantalum amagwiritsidwa ntchito popanga zida zosiyanasiyana, kuphatikiza ma rocket nozzles, zishango za kutentha, ndi zina zotentha kwambiri, zopanikizika kwambiri. Kuphatikizika kwa mphamvu, kukana kutentha, ndi kukana kwa dzimbiri kumapangitsa tantalum kukhala chisankho choyenera pamadera ovutawa.

Ponseponse, wapadera katundu wa zithunzi za tantalum zawapanga kukhala zinthu zofunika kwambiri pazantchito zosiyanasiyana zaukadaulo, kuyambira pamagetsi ndi zida zamankhwala kupita ku zida zamafakitale ndi zida zamlengalenga.

Ku SHAANXI CXMET TECHNOLOGY CO., LTD, timanyadira zamitundu yathu yayikulu, yomwe imathandizira zosowa zosiyanasiyana zamakasitomala. Kampani yathu ili ndi luso lapadera lopanga ndi kukonza, kuwonetsetsa kuti zinthu zathu ndi zapamwamba komanso zolondola.
