Nyumba ya Quartz ya Galasi:

MICQ imapereka mitundu itatu ya magalasi a quartz: Fused Quartz / Synthetic Quartz Silica / IR Quartz. Kupyolera muzitsulo zazikuluzikulu za katatu, ndipo zinapanga zolemera kapena zofunikira zazitsulo za quartz kuti zigwiritsidwe ntchito mmakampani, zamankhwala, kuunikira, ma laboratory, semiconductor, mauthenga, optics, magetsi, optics, malo opangira, asilikali, mankhwala, zokutira ndi zina zotero.

• Kuphunzitsa katundu:

  1. Chiyero: Chiyero ndi ndondomeko yofunikira ya galasi ya quartz. Zomwe zili mu SiO2 mu galasi wamba wa silika ndi zoposa 99.99%. Zomwe zili mu SiO2 mu galasi lopangidwa ndi makina a quartz ndipamwamba pamwamba pa 99.999%.
  2. Ntchito yogwira: Poyerekeza ndi galasi yeniyeni yeniyeni, galasi lamatenda a quartz ali ndi kuwala kwabwino kwambiri pa gulu lonse la wavelength. M'dera lamtundu wa infrared ndi lowoneka bwino, kusintha kwa masewera a galasi ya quartz kuli bwino kuposa galasi wamba. Mu ultraviolet spectral dera makamaka yochepa mawonekedwe ultraviolet spectrum, galasi ya quartz ndi bwino kuposa ena.
  3. Kukaniza: Kutentha kwa magalasi a quartz kumaphatikizapo kukana kutentha, kutentha matenthedwe, kusasinthasintha kwamatenthedwe, kutentha kwakuthupi ndi matenthedwe otenthetsa, makina amchere (omwe amadziwikanso kuti crystallization kapena kuperewera) komanso kutentha kwakanthawi. Chowonjezera chowonjezera cha magalasi a quartz ndi 5.5 × 10-7cm / cm ℃ monga 1/34 yamkuwa & 1/7 ya borosilicate. Makhalidwewa amagwiritsidwa ntchito pamunda wamagetsi opanga, mawindo otentha kwambiri ndi zinthu zina zomwe zimafunikira chidwi pakusintha kwamafuta pang'ono. Galasi ya Quartz popeza coefficient yowonjezera ndi yaing'ono, imakhala yotentha kwambiri, galasi ya quartz yowonekera m'ng'anjo ya 1100 ℃ pansi pa kutentha kwa mphindi 15, kenako mumadzi ozizira, omwe amatha kupirira mayendedwe 3-5 osaphulika. Malo ochepetsera galasi ya quartz ndiokwera kwambiri ngati galasi lowonekera bwino ndi 1730 ℃, chifukwa chake kutentha kopitilira muyeso kwa chida cha quartz ndi 1100 ℃ -1200 ℃, 1300 ℃ itha kugwiritsidwa ntchito munthawi yochepa.
  1. Machitidwe a mankhwala: Galasi ya Quartz ndi bwino acid acid. Kulimbitsa thupi kwake kumakhala kofanana ndi nthawi ya 30 ya asidi yosakanizidwa ndi ceramic, nthawi 150 ya nickel chromium alloy ndi yowonjezera ceramic pa kutentha kwapamwamba ndi kuikapo kwambiri kwa asidi ntchito yofunika kwambiri makamaka kupatula hydrofluoric acid ndi 300 ℃ phosphate. Galasi la quartz silingathe kusokonezeka ndi kuwonongeka kwa asidi, makamaka sulfuric acid, nitric acid, hydrochloric acid ndi aqua regia pa kutentha.
  1. Malo osungira: Mitengo ya galasi ya quartz ndi yofanana ndi ya magalasi ena, ndipo mphamvu yawo imadalira ming'alu yaing'ono mu galasi. Modulus of elasticity, mphamvu yokhazikika ndi flexural mphamvu ikuwonjezeka ndi kutentha kutentha, nthawi zambiri kufika pazitali pa 1050-1200 ℃. Zotchulidwa kuti zogwiritsa ntchito ndi mphamvu zowonjezera ndi 1.1 * 109Pa komanso mphamvu 4.8 * 107Pa.
  1. Malo amagetsi: Galasi ya Quartz ili ndi zida zokhazokha zazitsulo zamkuwa zomwe ndizosauka. Kuwonongeka kwa dielectric ndi kochepa kwambiri pafupipafupi. Monga zotetezera, mphamvu zake zamagetsi ndi zamakina zimakhala zabwino kwambiri kuposa za zipangizo zina. Pakati pa kutentha kwabwino, kusakanikirana kwapakati pa galasi lamadzimadzimadzi ndi 1019ohm cm, pofanana ndi nthawi 103-106 ya galasi yamba. Kukaniza kutsekemera kwa galasi lotsekemera ya quartz pa kutentha kwabwino ndi 43 zikwi volts / mm.
  1. Kuponderezedwa kutsutsa: Zopeka, mphamvu yamagetsi ndi yaikulu kwambiri kuposa mapaundi a 4 miliyoni pa mainchesi lalikulu, galasi lamakono ofanana ndi mphamvu yotsutsa-mphamvu ndi 3 ~ 5 nthawi za galasi wamba ndi kupindika mphamvu ndi 2 ~ 5 nthawi za galasi wamba. Galasi ikawonongeka ndi mphamvu yonyansa, tinthu tating'onoting'ono tomwe timakhala tomwe timapangitsa kuti thupi lathu liwonongeke.
  1. Kusagwirizana: Mankhwalawa amagwirizana ndi chikhalidwe chomwe chimayambitsa kuthetsa ming'alu, thovu, zosafunika, kutsekemera, kusintha kwa zina ndi zina zotero. Muzinthu zakuthupi ndi zamakhalidwe, zimakhala ndi chikhalidwe chokwanira kuti zitsimikizidwe bwino.
