Faeba ea khalase ea quartz ke eng?
Faeba ea khalase ea Quartzke thepa ea faeba e sa pheleng e nang le silicon dioxide (SiO₂) ea bohloeki ba ≥99.9% e le karolo ea eona e ka sehloohong. E hlahisoa ka mokhoa oa ho hula molamu oa silica o kopantsoeng. Thepa ena ea faeba e kopanya litšobotsi le thepa e ntle haholo ea quartz e tiileng, e leng se etsang hore e be thepa e ntle haholo e hanelang mocheso o phahameng. E ka boela ea kopanngoa le li-ceramic, alumina, nitrides le thepa e meng ka mefuta e fapaneng ho etsa thepa e kopaneng e nang le thepa e ikhethang. Khoele ea faeba ea Quartz e etsoa ka ho sotha le ho phunya li-filament tse tala.
Ke hobane'ng ha faeba ea quartz e le matla hakaale, hona litšobotsi tsa eona tse phahameng ke life?
1. Faeba ea khalase ea quartz e na le khanyetso e ntle ea mocheso o phahameng. Mocheso oa eona oa ts'ebetso oa nako e telele ke 1050-1200℃, 'me khanyetso ea eona ea mocheso o potlakileng e fihla ho 1700℃. E boloka matla a phahameng tlas'a maemo a mocheso o phahameng, e hanela ho thothomela ha mocheso le ho tlosoa ha motlakase, 'me e ka sebelisoa tšireletsong ea mocheso oa sefofane, li-nozzle tsa enjene ea rokete, le thepa ea ho thibela mocheso o phahameng.
2. E na le thepa e ntle ea dielectric le phetiso e ntle ea maqhubu. Phetiso ea eona ea dielectric e tlase ho 3.7, 'me coefficient ea eona ea tahlehelo ea dielectric ke <0.001>. E na le tahlehelo e tlase ea phetiso ea lets'oao la maqhubu a phahameng le phetiso ea maqhubu a phahameng (ho fihlela ho 99.3%), e leng e 'ngoe ea litšobotsi tsa bohlokoa tsa ts'ebetso tse e etsang hore e lokele li-dome tsa radar, li-radome tsa antenna, li-substrate tsa puisano tsa 5G, le lisebelisoa tsa tšireletso ea limisaele.
3. Faeba ea quartz e na le matla a phahameng a mechini. Matla a eona a ho thaepa a ka fihla ho >1500MPa, a teteaneng 2.29g/cm³, a bobebe empa a le matla a phahameng, a fokotsa boima ba lisebelisoa ha a ntse a boloka matla. Ho feta moo, e ka kopanngoa le lisebelisoa tse ling ho etsa li-composite reinforcements tse sebetsang hantle, e leng se etsang hore e be thepa ea bohlokoa bakeng sa likarolo tsa sebopeho sa satellite.
4. botsitso ba yona bo botle ba dikhemikhale bo a hlokomeleha. Ka dikahare tsa SiO₂ tse ≥99.9%, e bontsha ho se tsitse ha dikhemikhale le ho hanyetsa mafome, e ikamahanya le dibaka tse thata tsa dikhemikhale. Sena se etsa hore e be kgetho e ntle bakeng sa disebediswa tsa ho sebetsana le dikhemikhale tsa semiconductor, thepa ya ho sefa e nang le mocheso o phahameng, le dijari tsa dikhemikhale.
Lihlahisoa tse entsoeng ka faeba ea khalase ea quartz li sebelisoa masimong a mangata.
1. Boea ba quartz le felte ea boea ba quartz lia tsebahala ho ba etsang liteko tsa mocheso o phahameng. Tsena ke likhoele tse khutšoane tse bonolo tse entsoeng ka likhoele tsa quartz tse bululetsoeng kapa tse huloang, tse ka sebelisoang ka kotloloho kapa tsa etsoa felte. 1. Boea ba quartz bo khetholloa ka sebopeho sa bona se bobebe, se nang le masoba le ho tsamaisa mocheso o tlase, e leng se etsang hore e be thepa e ntle ea ho thibela mocheso o phahameng. Hangata e sebelisoa mealong ea ho thibela mocheso ea sepakapaka kapa lisebelisoa tsa indasteri tsa mocheso o phahameng. Likarolo tsa ho thibela mocheso tse tšoeu, tse bonolo, tse kang k'hothone le likarolo tsa ho thibela mocheso tse kang quilt liforomong tsa liforo tsa laboratori le liforo tsa annealing ke felte ea boea ba quartz le boea ba quartz.
2. Ho itšeha ho tsoelang pelelikhoele tsa quartzHo fihlela bolelele bo reriloeng esale pele ho hlahisa likhoele tsa quartz tse khaotsoeng. Tsena li ka kopanngoa le li-resin tse hanyetsanang le mocheso o phahameng e le li-ejenti tse matlafatsang le li-ejenti tse fetisang maqhubu, 'me tsa kopanngoa hammoho ho etsa thepa e thibelang mocheso kapa e thibelang mocheso bakeng sa likarolo tsa tlhahiso tse kang li-radome tsa missile.
3. Khoele ea faeba ea Quartz ke khoele e tsoelang pele 'me e sebetsa e le thepa ea motheo bakeng sa ho loha ho latelang. Kaha ke e 'ngoe ea likhoele tse sa fetoheng tse sa fetoheng tse hanelang mocheso le tse sebetsang hantle ka motlakase, hangata e sebelisoa e le karolo ea ho matlafatsa ho loha masela a fapaneng kapa ka ho toba bakeng sa ho kobeha le ho bopa thepa e kopaneng. Ho feta moo, theknoloji e tsoetseng pele ea ho loha ea mahlakore a mararo e lumella likhoele ho loha sebakeng. Sebopeho sena se na le botšepehi bo matla ka kakaretso, e leng se etsang hore e be sebaka se setle sa ho etsa likarolo tse bōpehileng joaloka tse rarahaneng, tse jarang moroalo o mongata joalo ka li-nozzle tsa enjene ea rokete.
4. Lesela la faeba la Quartze lohuoa ka khoele ho sebelisoa weave e bonolo, twill weave, satin weave, le lits'ebetso tse ling. Jwalo ka thepa e matlafatsang, e kopanngoa le matrices tse kang polyimide le epoxy resin ho etsa likarolo tsa sebopeho tse mocheso o phahameng bakeng sa lifofane, lirokete le limisaele, hammoho le thepa e thibelang mocheso kapa e hanelang ablation bakeng sa li-antenna tsa sathelaete le liboto tsa potoloho tse hatisitsoeng ka maqhubu a phahameng.
