Kodi cholinga cha titanium diboride ndi chiyani?

Cholinga cha Titanium diboride amapangidwa ndi titaniyamu diboride. Titanium diboride ndi chinthu chakuda chotuwa kapena chotuwa chokhala ndi makristalo hexagonal (AlB2), malo osungunuka mpaka 2980 ° C, kachulukidwe ka 4.52g/cm³, ndi microhardness ya 34Gpa, motero imakhala yolimba kwambiri.ess. Ili ndi oxidation kukana kutentha mpaka 1000 ℃ mumlengalenga, ndipo kumakhalabe kokhazikika mu HCl ndi HF zidulo, kuwonetsa kukana kwa dzimbiri kwa asidi.Zida zakuthupi ndi izi: coefficient of thermal expansion: 8.1 × 10-6m / m · k; Kutentha kwapakati: 25J/m·s·k; Kukana: 14.4μΩ·cm;

Nkhaniyi ilinso ndi matenthedwe abwino komanso magetsi, choncho imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, monga kupaka vacuum, zida zodulira ceramic ndi zisamere, crucible kutentha kwambiri, mbali za injini ndi zina zotero. Panthawi imodzimodziyo, chandamale cha titaniyamu diboride ndichofunikanso kwambiri pokonzekera ma alloys a titaniyamu, zitsulo zolimba kwambiri komanso kulimbitsa konkire.

 Momwe Mungapangire Chandamale cha Titanium Diboride?

1.Direct synthesis njira: Njirayi ndikuphatikiza mwachindunji titaniyamu ndi ufa wa boron mu riyakitala yotentha kwambiri kuti ipange titaniyamu diboride. Komabe, kutentha kwa njirayi kuyenera kukhala kopitilira 2000℃, mtengo wamtengo wapatali ndi wapamwamba, ndondomekoyi si yosavuta kulamulira, momwe zimakhalira sizikwanira, TiB2 yopangidwa ndi yotsika kwambiri, ndipo n'zosavuta kupanga TiB, Ti2B ndi mankhwala ena.

2.Njira ya borothermal: Njirayi imagwiritsa ntchito TiO2 (chiyero chapamwamba kuposa 99%, kapangidwe ka ase, kukula kwa tinthu 0.2-0.3μm) ndi amorphous B (chiyero 92%, kukula kwa tinthu 0.2-0.3μm) monga zopangira, kupyolera mu chiŵerengero chapadera ndi Mpira mphero ndondomeko (nthawi zambiri zimachitika pansi vakuyumu), pa anachita kutentha zosaposa 1100 ° C kukonzekera titaniyamu. diboride.

3. Sungunulani electrolysis: Mu njira iyi, titaniyamu oxides amachita ndi alkali (kapena zamchere lapansi) zitsulo borates ndi fluorates pansi zikhalidwe Sungunulani electrolysis kupanga titaniyamu dib.kukwera.
Iliyonse mwa njira zopangira izi ili ndi mawonekedwe ake, kusankha kwapadera komwe kumadalira pakupanga, mikhalidwe ya zida ndi ndalama zachuma ndi zina.

Kodi magawo ogwiritsira ntchito The titanium diboride target ndi ati?

Madera akuluakulu ogwiritsira ntchito titanium diboride ndi otakata kwambiri, makamaka kuphatikiza izi:
Conductive ceramic zakuthupi: titaniyamu diboride ndi chimodzi mwazinthu zazikulu zopangira vacuum TACHIMATA conductive evaporation bwato.
Zida zodulira Ceramic ndi nkhungu: zimatha kupanga zida zomalizira, kujambula waya kumafa, kufa kwa extrusion, zophulika mchenga, zinthu zosindikizira, ndi zina zambiri.
Composite ceramic zipangizo: titaniyamu diboride angagwiritsidwe ntchito monga chigawo chofunika Mipikisano chigawo chimodzi zipangizo, ndi TiC, TiN, SiC ndi zipangizo zina wopangidwa ndi gulu zipangizo, kupanga mbali zosiyanasiyana mkulu-kutentha ndi mbali zinchito, monga kutentha kwambiri. crucible, injini mbali, etc. Ndi chimodzi mwa zinthu zabwino kwambiri zopangira zida zodzitetezera.
Cathode ❖ kuyanika zinthu za aluminiyamu electrolyzer: Chifukwa wettability wabwino wa TiB2 ndi zitsulo zotayidwa madzi, ntchito titaniyamu diboride monga cathode ❖ kuyanika zinthu za zotayidwa electrolyzer akhoza kuchepetsa mowa zotayidwa electrolyzer ndi kutalikitsa moyo wa electrolyzer.
PTC Kutentha Ceramic zipangizo ndi kusintha PTC zipangizo: titaniyamu diboride akhoza kupangidwa ndi zipangizo zimenezi, ndi chitetezo, kupulumutsa mphamvu, odalirika, yosavuta processing ndi kupanga makhalidwe, ndi mtundu wa kusinthidwa mankhwala apamwamba cha mitundu yonse ya zipangizo Kutentha magetsi.
Zida zomangira zitsulo: Titanium diboride ndi njira yabwino yolimbikitsira A1, Fe, Cu ndi zida zina zachitsulo.
Zamlengalenga: Titanium diboride itha kugwiritsidwa ntchito kupanga ma rocket nozzles, zipolopolo zamlengalenga ndi zinthu zina kuti zipirire kutentha kwambiri komanso kupanikizika.
Munda wowongolera kutentha: Titanium diboride ili ndi matenthedwe abwino kwambiri ndipo imatha kugwiritsidwa ntchito ngati zida zamagetsi zamagetsi, kuyendetsa bwino kutentha kwa radiator kuti zitsimikizire kuti zida zamagetsi zikuyenda bwino.
Kubwezeretsa mphamvu ndi kupulumutsa mphamvu: Titanium diboride itha kugwiritsidwanso ntchito kupanga zida za thermoelectric zomwe zimatembenuza mphamvu yotentha kukhala magetsi.
Kuphatikiza apo, zolinga za titaniyamu diboride zimagwiritsidwanso ntchito kwambiri pamagalimoto, zamagetsi, mphamvu zatsopano, mabwalo ophatikizika, kusungirako zidziwitso ndi mafakitale ena.

Kodi cholinga cha titaniyamu diboride ndi zingati?

Mtengo wa titaniyamu diboride mipherezero zimasiyanasiyana kutengera mtundu, chiyero, kukula, tinthu kukula, ma CD specifications ndi zina.Malinga ndi mawu a ogulitsa ena, mtengo ukhoza kuyambira makumi khumi mpaka masauzande a yuan. Mwachitsanzo, mtengo wa zolinga za titaniyamu diboride ndi 85 yuan, 10 yuan (zoyesa kafukufuku wasayansi), 285 yuan (granular) 2000 yuan mipherezero kapena kupitilira apo (kuyera kwakukulu, magnetron sputtering). Tiyenera kuzindikira kuti mitengoyi ndi yongotchula chabe, mtengo weniweniwo ukhoza kusintha chifukwa cha kupezeka kwa msika ndi kufunikira, kusinthasintha kwamitengo yamtengo wapatali ndi zina.

Momwe mungasankhire chandamale chapamwamba cha titaniyamu diboride?

1.Maonekedwe ndi mtundu: Zolinga za Titanium diboride nthawi zambiri zimakhala zotuwa kapena zotuwira zakuda, ndipo maonekedwe ayenera kukhala ofanana popanda zonyansa zoonekeratu kapena mawanga amtundu. Ngati mtunduwo ndi wakuda kwambiri kapena wopepuka, kapena pali zonyansa pamwamba, zikhoza kusonyeza kuti chiyero chake sichili chapamwamba kapena pali vuto pokonzekera.
2.Chiyero: Chiyero ndi index yofunikira yoyezera mtundu wa chandamale cha titanium diboride. Kukwera kwa chiyero, kumakhala kokhazikika komanso kosadetsedwa. Kuyera kwa chandamale kumatha kuyesedwa ndi kusanthula kwamankhwala ndi njira zina kuti zitsimikizire kuti zikukwaniritsa zofunikira zogwiritsidwa ntchito.
3.Kachulukidwe ndi kuuma: Titaniyamu diboride ili ndi kachulukidwe kakang'ono komanso kuuma, komwenso ndi gawo lofunikira la magwiridwe ake abwino kwambiri. Poyesa kuchulukana ndi kuuma kwa chinthu chomwe mukufuna, mtundu wake ukhoza kuyesedwa koyambirira. Ngati kachulukidwe ndi kuuma sizikugwirizana ndi miyezo, zingasonyeze kuti pali vuto ndi ndondomeko yokonzekera kapena zopangira.
4.Magetsi ndi matenthedwe madutsidwe: Titanium diboride ali wabwino madutsidwe magetsi ndi matenthedwe madutsidwe, chimene ndi chifukwa chofunika kwambiri ntchito yake lonse m'munda wa zamagetsi ndi mphamvu. Kuwongolera kwamagetsi ndi kutentha kwa chandamale kungayesedwe poyesa resistivity ndi matenthedwe conductivity ya chandamale.
5.Kusanthula kaphatikizidwe ka mankhwala: Kupyolera mu kusanthula kapangidwe kakemikolo, zomwe zili ndi kuchuluka kwa zinthu zosiyanasiyana zomwe mukufuna kudziwa zitha kumveka, kuti muwone ngati zikugwirizana ndi muyezo. Ngati zomwe zili muzinthu zonyansa zomwe zili muzolingazo ndizokwera kwambiri, kapena chiwerengero cha zinthu zazikulu sichikugwirizana ndi zofunikira, zikhoza kusonyeza kuti khalidwe lake ndi losauka.
Kukonzekera: Kumvetsetsa ndondomeko yokonzekera chandamale kungathandizenso kuweruza ubwino wake. Ngati njira yokonzekera ikupita patsogolo ndipo kuwongolera kuli kolimba, zinthu zomwe mukufuna kukhala nazo zokhala ndi zabwino zambiri zimatha kupezeka. M'malo mwake, ngati njira yokonzekera ili m'mbuyo kapena yosayendetsedwa bwino, ubwino wa cholingacho ukhoza kukhala wosakhazikika kapena wolakwika.
6.Mbiri ya ogulitsa: Kusankha wogulitsa wodalirika ndi gawo lofunikira pakuwonetsetsa kuti zinthu zomwe mukufuna. Mutha kuyang'ana kuyenerera kwa ogulitsa, momwe amagwirira ntchito komanso kuwunika kwamakasitomala ndi zidziwitso zina kuti mumvetsetse mbiri yake komanso mulingo wamtundu wazinthu.
