Kushanda Kwakanaka KweAlumina Powder Muzvinhu Zvinoonekwa
Kana zvasvika kune alumina, vanhu vazhinji vanogona kutanga vafunga nezvezvinhu zvichena, zvakaoma zvemaindasitiri, zvinoita sezvisina chekuita nehunyanzvi hwepamusoro hwe optics. Zvakanaka, tenda kana kwete, izvozvo hazvina kukosha. Kana wangozvinzwisisa zvizere uye wazvigona, kunyanya kuwana kuchena kwakanyanya uye kutonga kwakarurama muchimiro cheupfu, basa rayo munyika ye optics rinoshamisa zvechokwadi, zvichiita kuti ive "nzvimbo ine simba shoma."
I. Kubva pa "Munhu Akaoma" kuenda pa "Kujeka": Kuchinja Kunoshamisa
Tose tinoziva izvozvoaluminaine zita rine mukurumbira—corundum, ine kuomarara kweMohs kwe9, yechipiri kune dhaimani, zvichiita kuti ive "munhu akasimba" chaiye. Ndiyo chikamu chikuru chematombo anokosha akadai sesafire neruby. Zvisinei, muzvinhu zvinopenya, chinangwa chikuru hachisi kuomarara, asi "kujeka"—kupenya kwakanaka, kuchena, uye kugadzikana.
Apa ndipo panopinda tekinoroji. Kuburikidza nemaitiro ekugadzira epamusoro, akadai sekupiswa kwealuminium ine purity yakakwira uye nzira dze hydrolysis dzakakosha, tinogona kuwana ultrafine uye ultra-yuniform.upfu hwealuminaine kuchena kunosvika 99.99% kana kunyange 99.999%. Musarerutsa kunaka uku; zvakafanana nekushandura mvura yerwizi ine matope kuita mvura yakachena yemugomo, zvichideredza tsvina kusvika padanho diki. Tichishandisa upfu uhwu hwakachena sekutanga, mushure mekuumba nekutsvaira, tinogona kugadzirira alumina ceramics ine chiedza chakanaka.
Chiumbwa ichi chedongo hachisisiri "munhu asina kujeka" asi "murume" anopenya kana kuti anotopenya. Kana chiedza chichipenya pachiri, chinobvumira chiedza chinoonekwa uye cheinfrared kupfuura nepakati, ukuwo chichichengetedza simba rayo guru, kuomarara kwakanyanya, kuramba ngura, uye kuramba kupisa kwakanyanya kwealumina. Hunhu uhwu hwe "mabasa maviri" hwakaita kuti chikwanise kuzviratidza nekukurumidza mumhuri yezvinhu zvinovheneka.
II. Mashandisirwo Anoshanda Anoratidza Simba Rechokwadi: Mbiru Dzenzvimbo Dzakakosha Dzakasiyana-siyana
Kutaura kwakachipa. Kushanda kwakanaka kwazvo kweupfu hwealuminamuzvinhu zvinovheneka imhedzisiro yekuedzwa kwenyika chaiyo. Ngatitarisei mienzaniso mishoma kubva muhupenyu hwedu hwezuva nezuva uye minda yemaindasitiri kuti tiratidze izvi.
1. Marambi eSodium: "Nhumbi Dzakajeka" Dzinovhenekera Husiku
Marambi mazhinji emumugwagwa akajeka mumaguta husiku marambi ane simba re sodium. Wakaona here kuti machubhu anopenya haasi magirazi akajairwa, asi chubhu ye ceramic inopenya? Alumina ceramic ndiyo inonyanya kutaurwa pano.
Sei zvakadaro? Chekutanga, sodium vapor inoparadza zvakanyanya kana ichipisa zvakanyanya uye ichimanikidzwa; girazi rakajairika harigoni kutsungirira uye rinofa mukati memazuva mashoma.Alumina zvedongo, kune rumwe rutivi, haipindi ngura, inoramba yakasimba pasinei ne "dambudziko" re "sodium vapor". Chechipiri, inofanirwa kushanda yakagadzikana kwenguva yakareba patembiricha inosvika zviuru zvemadhigirii Celsius, uko kudzivirira kupisa kwakanyanya kwealumina kunobatsira. Chinonyanya kukosha, inofanira kubvumira chiedza chinooneka kuti chipfuure nepakati zvinobudirira panguva imwe chete isingapindi nesodium vapor. Sezvaunogona kuona, simba rayo guru, kudzivirira ngura zvakanyanya, kudzivirira kupisa kwakanyanya, uye kupenya kwakajeka—zvinodiwa izvi zvakasimba zvakabatanidzwa zvinoita kuti alumina ceramics ive sarudzo chete inoshanda. Chinonyanya kukosha pane izvi zvese ihupfu hwealumina hwakanyatsosarudzwa uye hwakanyatsogadzirwa.
2. Mahwindo eInfrared neFairings: "Maziso Akajeka" eMabhomba neMadhiraivha
Munzvimbo dzemauto nedzemuchadenga, vanotsvaga zvombo zvinokandwa uye masisitimu ekuona zvinhu zvinokandwa mudenga zvemotokari dzinomhanya zvakanyanya zvinoda nhoo yekudzivirira, kana kuti "hwindo" kana "fairing." Zvinodiwa pakuita izvi zvakatokura: hazvifanirwe kungosimba zvakakwana kuti zvikwanise kutsungirira kuputsika kwemhepo inomhanya zvakanyanya uye kukanganiswa nemadonhwe emvura neguruva, asi zvinofanirawo kuendesa chiedza cheinfrared muma wavelength chaiwo, zvichibvumira ma detector emukati "kuona" nyika yekunze.
Apa ndipo panobva paonekwa zvakare zviumbwa zve alumina zvinopenya kana kuti zvinopenya. Kuoma kwayo kwakakwana kudzivirira kuparara kwenzvimbo dzakaoma, uye mashandiro ayo ekufambiswa kwe infrared akanaka kwazvo, kunyanya pakati nepakati pe infrared. Fungidzira chombo chinofamba mudenga guru rehusiku. "Maziso" aro isimbi yakagadzirwa ne alumina ceramic, ichidzivirira system ye optical yemukati uye ichitungamira chombo nemazvo kusvika pachinangwa chayo. Basa iri guru harigoneki sezvinhu zvakajairwa.
3. Zvishandiso zvemhando yepamusoro: "Stage Yakasimba" yeIntegrated Circuit Optical World
Nekufambira mberi kwetekinoroji, zvishandiso zvakaita sema LED, ma laser, uye ma optical sensors zvinowanzoda "danho" rakatsiga, rakati sandara, rinodzivirira kupisa, uye rinofambisa kupisa kuti rishande. Alumina ceramic substrates ndiyo "danho" rakanaka kwazvo iri.
Saizvozvowo, kunaka kwe "danho" iri kunoenderana zvakananga nehunhu hwe "zvidhinha" zvaro - izvoupfu hwealumina. Kuchena kweupfu hwakawanda kunoita kuti pave nechinhu chakaita segirazi pamusoro pechinhu chakatsvuka, zvichideredza kupenya kwechiedza uye kupindira kwemhepo; zvidimbu zvakafanana uye zvakapfava zveupfu zvinovimbisa chimiro chakakora chakatsvuka, chisina maburi nezvimwe zvikanganiso, zvichikonzera kudzikamisa kwakanaka kwemagetsi uye kufambisa kwemhepo. Kutenderera kwakaomarara pamafoni edu kunogona kunge kuripo nekuda kwezvigadziko zve alumina ceramic, kunyange zvazvo zvichiramba zvakavanzika kubva pakuonekwa. III. Nei Zvichidaro? Ngatitaurei Nezve "Kubudirira" Kwayo Kwemukati
Mushure mekukurukura mashandisirwo akawanda akadai, ngationgororei kuti nei alumina powder iri yakanaka kudaro. Pakupedzisira, imhaka yehunhu hwayo hwakanaka kwazvo, hunoenderana zvakakwana nezvinodiwa zvezvinhu zvinovheneka:
Kushanda Kwemaziso Kunodzorwa: Nekudzora kuchena kwehupfu, saizi yezvikamu, uye maitiro ekupisa, kutumirwa uye indekisi ye refractive yechigadzirwa chekupedzisira checeramic mumabhandi e ultraviolet, anoonekwa, uye infrared zvinogona kudzorwa nemazvo.
Simba Rinoshamisa reMichina: Kuomarara kwakanyanya, simba guru, uye kusimba kwakanyanya kunoita kuti igare kwenguva refu uye ishande kwenguva refu.
Hunhu Hwayo Hwemakemikari Hunogara Nesimba: Yakagadzikana zvakanyanya, haibatike nyore nyore neacids, alkalis, munyu, nezvimwe zvinhu zvakawanda zvemakemikari, uye inogona kutsungirira mamiriro akasiyana-siyana akaomarara.
Kugadzikana Kwakanaka Kwekupisa: Nekunyunguduka kuri pamusoro pe2050℃ uye kuwedzera kwekupisa kuri pasi, chimiro chayo nehukuru hwayo hazvichinji kana tembiricha yakakwira, uye ine simba rakanaka rekudzivirira kupisa (kureva kuti, haityi kuchinja kamwe kamwe kwekupisa).
Inyanzvi yekudzivirira magetsi: Kudzivirira kwayo kwakanyanya kunoita kuti ive insulator yakanaka, yakakosha mumasisitimu akabatanidzwa e optoelectronic.
Sezvamunoona, hunhu uhwu hwakasanganiswa hunoita kuti zviite sekuti zvakagadzirirwa kushandiswa kwakasiyana-siyana kwemaziso. Uyezve, kana tichienzanisa nezvimwe zvinhu zvemaziso zvakaita semakristaro esapphire single, kugadzira zviumbwa zveceramic zvinopenya kubva muupfu kune zvakanakira zvikuru uye kuchinjika mukutonga mitengo uye kugadzira maumbirwo akaomarara uye zvigadzirwa zvikuru. Saka, musazvidza alumina powder zvakare!
