Chinsinsi cha Graphite Siketi ya Carbider: Chinsinsi cha ma metalgy apamwamba

M'dziko la metaldurgy ndi zida sayansi,opambanandi chida chofunikira chosungunuka ndi kuponyera zitsulo. Mwa mitundu yosiyanasiyana ya zolimba, sikiclen acbides carbide (sic) zopaka zawo, monga kuchuluka kwamphamvu, kukhazikika kwamphamvu kwa mafuta, komanso kukhazikika kwa mankhwala. Munkhaniyi, tidzayambiranso chinsinsi cha zojambulajambula za graphite sycible zomwe zimawonetsera ndikufufuza momwe kapangidwe kawo kamathandizira ntchito yawo yodabwitsa pakugwiritsa ntchito kutentha kwambiri.

Zosakaniza zoyambira

Zigawo zikuluzikulu za zojambulajambula za graphite ndizomera grake graphite ndi silicon carbide. Flake graphite, nthawi zambiri amapanga 40% -50% ya choopsa, amapereka mawonekedwe abwino kwambiri othandizapo, omwe amathandizira kumasulidwa kosavuta kwa chitsulo choponyedwa. Silicon carbide, ndikupanga 20% -50 -50% ya zoopsa, ndiye udindo wambiri wamawu owuma ndi kukhazikika kwamankhwala pa kutentha kwambiri.

Zowonjezera zina zowonjezera

Kupititsa patsogolo kutentha kwatentha kwambiri ndi kukhazikika kwa mankhwala kwa opambana, zowonjezera zina zimawonjezeredwa ku Chinsinsi:

1. Zoyeserera za silican ufa (4% -10%): Zimathandizira kulimba kwambiri kwamphamvu ndi makutidwe ndi oxidation kukana mphamvu.
2. Boron carbide ufa (1% -5%): Kuchulukitsa kukhazikika kwa mankhwala ndikulimbana ndi zitsulo zotupa.
3. Clay (5% -15%): amachita ngati chofunda ndikusintha mphamvu yamakina ndi kukhazikika kwa mphamvu ya opambana.
4. Thermosetting Ban (5% -10%): Amathandizira kumanga zinthu zonse pamodzi kuti apange mawonekedwe a coutheve.

Njira yomaliza

Pazogwiritsa ntchito zofunitsa ngakhale magwiridwe apamwamba kwambiri, njira yopumira ya graphite imagwiritsidwa ntchito. Formula iyi imakhala ndi 58% ma calphium, 2% calcium oxide, 1% zirconium oxide, 1% Boric acid, 1% sodic sallem, ndi 1% aluminium slika. Izi zowonjezera zimapereka kukana kosayerekezeka kwa kutentha kwambiri komanso zamankhwala zamankhwala.

Kupanga

Kukonzekera kwa zojambulajambula za graphite kumaphatikizapo njira yodziwikiratu. Poyamba, flake grake graphite ndi silicon carbide amasakanikirana bwino. Kenako, silika woyenera ufa, boron carbide ufa, dongo, ndi wowonda thonje akuwonjezeredwa ku osakaniza. Kuphatikizikako kumangirizidwa kumapangidwe pogwiritsa ntchito makina owonera ozizira. Pomaliza, zolimba zonenedwazo zimatsutsidwa mu ng'anjo yapamwamba kwambiri kuti ipititse mphamvu yamakina ndi kukhazikika kwa mafuta.

Ntchito ndi Ubwino

Zida zojambula zojambulajambula zimagwiritsidwa ntchito kwambiri pamakampani azitsulo osungunuka ndikuyipitsa zitsulo monga chitsulo, chitsulo, mkuwa, ndi ziphuphu. Kuchita manyazi kwambiri ndi kuwonjezeka kwa ma yunifolomu komanso kumachepetsa kugwiritsa ntchito mphamvu. Kuzunza kwakukulu kwa mafuta kumachepetsa chiopsezo cha kuwonongeka pakusintha kwa kutentha msanga, pomwe kukhazikika kwawo kumatsimikizira kuyera kwa chitsulo chosungunula.

Pomaliza, njira yomwe imayendera ya graphite ya carbider imaphatikizana ndi mawonekedwe abwino a zida zomwe zimapangitsa chidwi cha matenthedwe, kupha mafuta, komanso kukhazikika kwamankhwala. Ndondomeko iyi imawapangitsa kukhala ofunika kwambiri m'munda wa metalloggy, komwe amachita mbali yofunika kwambiri yofalikira komanso yopumira ndikuponyera zitsulo.

Mwa kumvetsetsa zigawozo ndi njira zopangira zojambulajambula, mafakitale amatha kupanga chisankho pazinthu zenizeni, ndikuwonetsetsa kuti ndi nthawi yoyenera komanso yokhazikika yamphamvu. Pamene ukadaulo umapita patsogolo, njira zina zothandizira mu njira yopanga zojambulajambula zojambula zomwe zimayembekezeredwa, ndikusintha njira yothandiza kwambiri komanso yokhazikika.
