Kodi ulusi wa galasi wa quartz ndi chiyani?
Ulusi wa galasi wa quartzNdi ulusi wosapangidwa ndi zinthu zachilengedwe wokhala ndi silicon dioxide (SiO₂) wa ≥99.9% woyera ngati gawo lake lalikulu. Umapangidwa kudzera mu njira yojambulira ndodo ya silica yosakanikirana. Ulusi uwu umaphatikiza makhalidwe abwino kwambiri ndi zinthu zabwino kwambiri za quartz yolimba, zomwe zimapangitsa kuti ikhale chinthu chabwino kwambiri cholimba kutentha kwambiri. Itha kupangidwanso ndi zoumba, alumina, nitrides, ndi zinthu zina m'njira zosiyanasiyana kuti ipange zinthu zophatikizana zokhala ndi zinthu zapadera. Ulusi wa ulusi wa quartz umapangidwa popotoza ndi kupotoza ulusi wosaphika.
Nchifukwa chiyani ulusi wa quartz ndi wamphamvu kwambiri, ndipo ndi zinthu ziti zabwino kwambiri zomwe ulusi wake uli nazo?
1. Ulusi wa galasi la quartz uli ndi kukana kutentha kwambiri. Kutentha kwake kwa nthawi yayitali ndi 1050-1200℃, ndipo kukana kutentha nthawi yomweyo kumafika 1700℃. Umasunga mphamvu zambiri pa kutentha kwambiri, umalimbana ndi kutentha kwambiri komanso kuchotsedwa kwa mpweya, ndipo ungagwiritsidwe ntchito poteteza kutentha kwa ndege, ma nozzles a injini ya rocket, ndi zipangizo zotetezera kutentha kwambiri.
2. Ili ndi mphamvu zabwino kwambiri za dielectric komanso ma wave transmission abwino. Dielectric constant yake ndi yotsika kufika pa 3.7, ndipo dielectric loss coefficient yake ndi <0.001>. Ili ndi ma high-frequency signal loss otsika komanso high wave transmission (mpaka 99.3%), yomwe ndi imodzi mwamakhalidwe ofunikira omwe amaipangitsa kukhala yoyenera ma radar domes, antenna radomes, 5G communication substrates, ndi zida zoteteza ma missile.
3. Ulusi wa quartz uli ndi mphamvu zambiri zamakanika. Mphamvu yake yolimba imatha kufika >1500MPa, kuchuluka kwa 2.29g/cm³, kapangidwe kopepuka koma kolimba kwambiri, kuchepetsa kulemera kwa zida pamene ikusunga kulimba. Kuphatikiza apo, ikhoza kuphatikizidwa ndi zipangizo zina kuti ipange zolimbitsa zophatikizika bwino, zomwe zimapangitsa kuti ikhale chinthu chofunikira kwambiri pazigawo za kapangidwe ka satellite.
4. Kukhazikika kwake kwabwino kwambiri kwa mankhwala n'kodziwika bwino. Ndi kuchuluka kwa SiO₂ ≥99.9%, imakhala ndi kukana kwamphamvu kwa mankhwala komanso kukana dzimbiri, zomwe zimapangitsa kuti ikhale yogwirizana ndi malo ovuta a mankhwala. Izi zimapangitsa kuti ikhale chisankho chabwino kwambiri cha zida zogwiritsira ntchito semiconductor, zida zosefera kutentha kwambiri, komanso zonyamula mankhwala.
Zinthu zopangidwa ndi ulusi wa galasi la quartz zimagwiritsidwa ntchito m'magawo ambiri.
1. Ubweya wa quartz ndi ubweya wa quartz ndizodziwika bwino kwa anthu omwe akuchita mayeso otentha kwambiri. Ubweya uwu ndi ulusi waufupi wofewa wopangidwa ndi ulusi wa quartz wophulika kapena wokokedwa, womwe ungagwiritsidwe ntchito mwachindunji kapena kupangidwa ngati feliti. 1. Ubweya wa quartz umadziwika ndi kapangidwe kake kopepuka, kokhala ndi mabowo komanso kutentha kochepa, zomwe zimapangitsa kuti ukhale chinthu chabwino kwambiri chotetezera kutentha kwambiri. Umagwiritsidwa ntchito kwambiri m'zigawo zotetezera kutentha za mlengalenga kapena m'zida zamafakitale zotenthetsera kutentha kwambiri. Zigawo zoyera, zofewa, zotenthetsera ngati thonje ndi zigawo zotetezera kutentha ngati buledi pamapulatifomu m'zitofu za machubu a labotale ndi zitofu zotenthetsera ndi feliti ya ubweya wa quartz ndi ubweya wa quartz.
2. Kudula mosalekezaulusi wa quartzKutengera kutalika komwe kunakonzedweratu, kumatulutsa ulusi wodulidwa wa quartz. Izi zitha kusakanikirana ndi ma resin osatentha kwambiri monga zinthu zolimbitsa ndi zinthu zotumizira mafunde, ndikupangidwa pamodzi kuti apange zinthu zoteteza kutentha kapena zoteteza kutentha zopangira zinthu monga ma missile radomes.
3. Ulusi wa quartz ndi ulusi wopitilira ndipo umagwiritsidwa ntchito ngati maziko a ulusi wolukira pambuyo pake. Popeza ndi umodzi mwa ulusi wosasinthika kwambiri wosagwira kutentha komanso wothandiza kwambiri pamagetsi, nthawi zambiri umagwiritsidwa ntchito ngati gawo lolimbitsa kuluka nsalu zosiyanasiyana kapena mwachindunji popangira ndi kuumba zinthu zophatikizika. Kuphatikiza apo, ukadaulo wapamwamba wolukira wa magawo atatu umalola ulusiwo kulukidwa mlengalenga. Kapangidwe kameneka kali ndi ulusi wolimba, zomwe zimapangitsa kuti ikhale yopanda kanthu kopangira zinthu zooneka ngati zovuta, zonyamula katundu wambiri monga ma nozzle a injini ya rocket.
4. Nsalu ya ulusi wa quartzAmalukidwa kuchokera ku ulusi pogwiritsa ntchito nsalu yosalala, nsalu yoluka ya twill, nsalu ya satin, ndi njira zina. Monga chinthu cholimbitsa, chimaphatikizidwa ndi ma matrices monga polyimide ndi epoxy resin kuti apange zida zomangira zotentha kwambiri za ndege, maroketi, ndi ma missile, komanso zipangizo zoteteza kutentha kapena zosagwira ntchito za ma antenna a satellite ndi ma circuit board osindikizidwa pafupipafupi.
