Chomera cha thovu chili ndi malo apadera mu sayansi ya zinthu ndi kupita patsogolo kwake. Kuchuluka kochepa, ma porosity ndi mphamvu zabwino zotetezera zinthuzo zimapangitsa kuti zikhale zothandiza pa ntchito zosiyanasiyana. Nkhani yomwe ili pansipa ikufotokoza mbali zosiyanasiyana ndikufotokozera njira zosiyanasiyana zogwiritsira ntchito thovu.Kupanga zinthu zadothi.
Kodi n’chiyani chimapangitsa thovu la ceramic ndi lachitsulo kukhala lotchuka?
Ma foams, kaya ndi ceramic kapenathovu lachitsuloAmapangidwa ndi mpweya wodzaza m'mabowo a chinthu choyambira. Mabowo amatha kutsekedwa kapena kutsekedwa mwanjira ina kapena kulumikizidwa ndikusiyidwa otseguka. Chinthu chachikulu chomwe chimafotokoza khalidwe la thovu ndi kutalika kwa mabowo omwe ali nawo. Kawirikawiri, mabowo kapena malo opanda kanthu amakhala pakati pa 75 - 90% ya chinthu choyambira.
Mafosholo a aluminiyamu vs Mafosholo a Ceramic: Kuyerekeza
Ma thovu a aluminiyamu
Mwachidule, thovu lachitsulo ndi chitsulo chodzaza ndi malo odzaza mpweya omwe amakhala ndi gawo lalikulu la voliyumu yawo. Thovu lachitsulo lapamwamba nthawi zambiri limapangidwa kuti aluminiyamu ikhale chitsulo choyambira.thovu lachitsuloYopangidwa ndi aluminiyamu komwe ma pores amapangidwa ndi mpweya kulowa mu chitsulo chotentha. Gasi kapena chotulutsira madzi chingagwiritsidwe ntchito kupanga ma pores mu aluminiyamu yosungunuka.
Kapangidwe kathovu lachitsulo la aluminiyamuIli ndi ulusi wa aluminiyamu wolumikizana womwe uli ndi mitundu iwiri. Mitundu iwiri yaThovu lachitsulo la aluminiyamundi mtundu wa maselo otsegukathovu la aluminiyamukapena mtundu wa selo lotsekedwa. Ntchito yaikulu ya thovu ndi yakuti thovu la aluminiyamu limasinthabe malinga ndi makhalidwe abwino omwe munthu amafunikira. Malo akuluakulu, mawonekedwe osiyanasiyana, ndi kulemera kopepuka ndi zinthu zokongola zaMa thovu a aluminiyamu.

Kodi thovu lachitsulo limapangidwa bwanji?
Njira yotchuka yopangiraThovu la aluminiyamu kapena thovu lachitsuloNjira yopangira mpweya ndiyo njira yopangira mpweya. Gawo loyamba limaphatikizapo kukonzekera chitsulo chopangidwa ndi matrix pogwiritsa ntchito ma oxides a aluminiyamu ndi magnesium kapena silicon carbide. Mpweya ukasungunuka, nayitrogeni kapena argon amabayidwa kudzera mu nozzle kapena impellers kuti zitsimikizire kuti zikupezeka mofanana mu chisakanizocho.
Njira ina yopangira thovu lachitsulo ndikugwiritsa ntchito chopukutira. Kuwola komwe kumabwera chifukwa cha kutentha kumapangitsa kuti chopukutiracho chitulutse mpweya ndikupanga mipata. Makampani amagwiritsanso ntchito njira ina yopangira mpweya wolimba kuti apangitse thovu pamaso pa haidrojeni. Pakupanga kotereku, ma pores amakhala kuyambira 10 micrometer mpaka 10 mm.
Ma thovu a ceramic
Ma thovu a ceramic chifukwa cha kapangidwe kake ka maselo akhala gawo lofunika kwambiri popanga zinthu. Kupanga kosavuta kumaphatikizapo kugwiritsa ntchito ma polima okhala ndi matope a ceramic. Thupi limasunga ceramic mu kapangidwe kake komwe kutentha kwambiri ndi mphamvu zotetezera zawonjezera phindu. Thovu la ceramic limagwiritsidwa ntchito m'njira zosiyanasiyana monga kutenthetsa kutentha, kutenthetsa mawu ndi ntchito zosiyanasiyana zomwe zimafuna mphamvu zambiri.

Mabowo m'maselo ndi ofanana kukula kwake ndipo nthawi zambiri amayesedwa mu mamilimita mpaka ma micrometer. Ngakhale kuti ma foam a ceramic okhala ndi mabowo ndi olimba ndipo mabowo amakhala ndi mpweya kapena mpweya mpaka 95 - 96%.
Pali mitundu yosiyanasiyana ya thovu la ceramic lopangidwa ndi Silicon Carbide, Alumina, Zirconia, Titania ndi Silica. Thovu la ceramic limadziwika ndi kupepuka kwake. Lili ndi mphamvu yolowera bwino kuzinthu zina. Mphamvu yopondereza ya thovu la ceramic ndi yabwino kwambiri.
Kapangidwe ka thovu la ceramic kameneka kamapangitsa kuti likhale labwino kwambiri popangira makina.
Kugwiritsa ntchito thovu la Ceramic
Kapangidwe kakang'ono ka zinthu zopangidwa ndi ceramic kakhala kothandiza kwambiri pamakampani opanga zinthu zamagetsi. Ndi kothandiza popanga zinthu monga mabatire, ma electrode ndi zina zotero.
Mphamvu zotetezera kutentha za ceramic zimagwiritsidwa ntchito poteteza kutentha bwino. Zingagwiritsidwe ntchito ngati zipangizo zomangira poteteza kutentha kuti zikhale ndi mphamvu komanso mphamvu ziwiri.
Ma thovu a ceramic angagwiritsidwe ntchito poletsa kuipitsa. Kulowa kwa madzi m'nthaka kumawapangitsa kukhala chinthu chothandiza polimbana ndi kuipitsa. Ma thovu a ceramic amapereka malo oti ma catalyst azisungunuka tinthu tating'onoting'ono tomwe tagwidwa.

Njira zopangira zinthu za ceramic
Njira zina zodziwika bwino zopangira thovu la ceramic zaperekedwa pansipa kuti zigwiritsidwe ntchito:
Njira Yopangira Thovu Molunjika
Njirayi imayamba mwa kupanga matope a ceramic omangika kenako ndi thovu. Polima ikatha, nkhungu imachotsedwa ndipo thovu lomwe limapangidwa limauma kenako limasungunuka. Njirayi imapanga malo olimba omwe amatha kupirira makina apamwamba.
Njirayi imathandizidwa ndi chinthu chotulutsa thovu chomwe chimayambitsa thovu chikasakanizidwa ndi matope a ceramic kenako chimakhazikika kenako ndikukhazikika. Kupanga kwa ceramic kochokera ku thovu mwachindunji kumadziwika kuti ndikosavuta komanso kodalirika ndipo ndikothandiza kulamulira porosity. Kukhazikika nthawi zambiri kumachitika zowonjezera zikafufuzidwa bwino.

Madera azachipatala a ma implants ndi nyumba zothandizira
Njirayi imatsimikizira kuwongolera kwa porosity ndi kuchuluka kwa kufanana.
Njira Yobwerezabwereza
Njira yobwerezabwereza imaphatikizapo njira yakupanga zinthu zoumbamomwe thovu la ceramic limaphimbidwa ndi thovu. Thovu la polymeric limatenthedwa pambuyo pake kudzera mu Sintering. Izi zidzafanana ndi thovu la ceramic lomwe poyamba limawoneka ngati thovu la polymeric. Thovu la ceramic lomwe limapangidwa ndi ukadaulo wobwerezabwereza limakhala ndi mphamvu zambiri komanso mphamvu zochepa.
Kugwiritsa Ntchito ndi Ubwino
Amagwiritsidwa ntchito popanga ma geometri ovuta monga mafupa omwe amaikidwa m'munda wa biomedical
Makampani opanga magalimoto ndi ndege nthawi zambiri amagwiritsa ntchito zinthu zadothi zopangidwa ndi njira yofanana chifukwa cha kulemera kwake kopepuka.
Kuganizira mosamala pankhaniyi kumatsimikizira kuti palibe zolakwika zomwe zikupezeka mu mawonekedwe ofunikira a zinthuzo.
Njira yogwirizanitsa starch
Njira yopangira starchkupanga zinthu zoumbaNthawi zambiri ndi yotsika mtengo ndipo siimayambitsa poizoni. Ndi yotetezeka ku chilengedwe ndipo imagwiritsa ntchito kutentha kwa madigiri pafupifupi 300 mpaka 600 poyatsa. Kutenthako kumaonetsetsa kuti palibe cholakwika chilichonse popanga thovu la ceramic.
Chosakaniza cha gelling monga chakudya cha starch chimayikidwa mu ufa wa ceramic kenako n’kusakaniza ndi madzi osungunuka. Kenako chisakanizocho chimachitika monga kusakaniza, kupopera, kuuma kenako n’kuumitsa. Chinthucho chikauma, chimatenthedwa pa kutentha kwakukulu kenako n’kupanga thovu la ceramic.

Njira ya Emulsion
Mu njira ya emulsion, monga momwe dzinalo likusonyezera, ma emulsion amagwiritsidwa ntchito pochita izi.kupanga zinthu zoumbakupanga thovu. Tinthu ta ceramic timapangidwa kuti tiike mu chisakanizo chopangidwa ndi zakumwa ziwiri zosasakanikirana. Emulsion ikapangidwa ndikukhazikika, gawo lina lamadzi limachotsedwa ndi nthunzi kapena kuyaka.
Kugwiritsa Ntchito ndi Ubwino
Njira yogwiritsira ntchito emulsion imatsimikizira kuti fyuluta imagwira ntchito bwino, motero imadziwika kwambiri m'makina osefera.
Amagwiritsidwa ntchito popanga zinthu zoteteza kutentha zomwe zimakhala ndi porous ndipo zimakhala zopepuka.
Ngakhale kuti njira imeneyi imatsimikizira kukula kwa machubu abwino komanso kufalikira kofanana, kufunika kwa njira yopangirayi kumapangitsa kuti njirayo ikhale yovuta kugwiritsa ntchito.
Njira ya Sol gel
Njira ya Sol gel monga momwe dzinalo likusonyezera ndi kusintha kwa yankho kukhala kapangidwe ka ceramic pomwe zinthu za mankhwala zikuwongoleredwa mu sitepe. Mu njira ya Sol gel yakupanga zinthu zoumbaMa porosity amawongoleredwa bwino popanda kuwononga mphamvu yofunika ya zinthuzo.
