Siyani uthenga

Magalasi a quartz amapangidwa ndi kusungunula mitundu yosiyanasiyana ya quartz zachilengedwe.

Coefficient yake yakukulitsa kutentha ndi yotsika kwambiri, 1/10 mpaka 1/20 yokha yagalasi wamba, ndipo imapereka kukana kwamphamvu kwamatenthedwe. Komanso sichitha kutentha kwambiri-, ndipo imakhala ndi kutentha kwapakati pa 1100 mpaka 1200 digirii komanso -kutentha kwanthawi kochepa kufika madigiri 1400 .

Magalasi a quartz amagwiritsidwa ntchito makamaka m'zida za labotale komanso kuyenga zinthu zapadera-zoyeretsa kwambiri. Kutumiza kwake kowoneka bwino kumapangitsa kuti isawonongeke ndi kuwonongeka kwa cheza (magalasi ena amadetsedwa akayatsidwa ndi cheza), kupangitsa kuti ikhale yabwino kugwiritsidwa ntchito mumlengalenga, mazenera amphepo, ndi makina owonera a spectrophotometer.
Magalasi a Quartz ndi galasi lapadera la mafakitale lomwe limapangidwa ndi silicon dioxide yokha. Imawuma kwambiri, imafika ku Mohs 7, ndipo imakhala ndi-kutentha kwambiri, kutsika kocheperako komwe kumawonjezera kutentha, kusasunthika kwamphamvu kwamafuta, kusasunthika kwamankhwala, komanso mphamvu zabwino kwambiri zotsekera magetsi.

Imawonekeranso ku cheza cha ultraviolet ndi infrared. Imawonetsa kukana kwa asidi wabwino ku ma acid wamba, kupatula hydrofluoric acid ndi hot phosphoric acid. Amagawidwa mowonekera m'magulu awiri: owonekera ndi opaque. Ukhondo wagawidwa m'magulu atatu: ukhondo wapamwamba-, wamba, ndi wamba. Amapangidwa kuchokera ku crystal, silica, ndi silicide kudzera-kutentha kwambiri kapena kuyika nthunzi wa mankhwala. Njira zosungunulira zimaphatikizapo kusungunula kwamagetsi ndi kuyenga gasi.

Pali mitundu yosiyanasiyana ya silika ya Fused yomwe imagwiritsidwa ntchito mosiyanasiyana. Tili ndi mitundu itatu, kuphatikiza JGS1, JGS2, JGS3

JGS1 (Galasi la Far UV Optical Quartz)Ndi galasi la quartz lopangidwa ndi mwala wopangidwa ndi SiCl 4 ngati zopangira ndipo zimasungunuka ndi chiyero chamoto wa oxyhydrogen. Chifukwa chake ili ndi kuchuluka kwa hydroxyl (mozungulira 2000 ppm) ndipo imakhala ndi magwiridwe antchito abwino kwambiri a UV. Makamaka m'dera lalifupi la UV, machitidwe ake otumizira ndiabwino kwambiri kuposa magalasi ena onse. Kuchulukitsa kwa UV pa 185nm kumatha kufika 90% kapena kupitilira apo. Magalasi a quartz opangidwa amafika pachimake champhamvu kwambiri pa 2730 nm ndipo alibe mawonekedwe. Ndi chinthu chowoneka bwino kwambiri chofikira 185-2500nm. JGS1 imagwiritsidwa ntchito pa ma Optics omwe akugwira ntchito mu UV akuya komanso mawonekedwe owoneka bwino a Laser, Magalasi, Windows, Prisms ndi Magalasi, ndi zina. Ndiwopanda thovu komanso zophatikizika. JGS1 Fused Silica ndi yofanana ndi Opanga Otsatirawa Heraeus - Suprasil 1 ndi 2 Saint-Gobain - Spectrosil A ndi B Corning's 7980 Dynasil's 1100 ndi 4100.

JGS2 (Galasi la UV Optical Quartz)
Ndi galasi la quartz lopangidwa ndi kuyeretsa gasi ndi krustalo ngati zopangira, zomwe zimakhala ndi zonyansa zambiri za PPM. Pali nsonga zoyamwa (hydroxyl content 100-200ppm) pa 2730nm, yokhala ndi mizere ndi tinthu tating'ono. Ndizinthu zabwino mu gulu la wave wave 220-2500 nm. Ubwinowu ukuphatikiza UV wabwino komanso kufalikira kowoneka kofanana ndi JGS1. Itha kupangidwa m'madiameter ang'onoang'ono / miyeso yomwe imatha kukhala yoonda kwambiri komanso yopanda thovu. Kuipa kumaphatikizapo thovu lotheka mu miyeso yokulirapo/mamita.

JGS2 Fused Silica ndi yofanana ndi Opanga otsatirawa
Heraeus 'Homosil 1,2; 3
Dynasil 1000; 4000; 5000; 6000

Mapulogalamu a JGS2 akuphatikizapo:

mawonekedwe a condenser;kutentha kwambiri ndi zipangizo zokakamiza

mawonekedwe a kuwala;zithunzi za microscope;magalasi owonera

3. (Galasi la Infrared Optical Quartz) JGS3

JGS3 ndi yowonekera mu ultraviolet, zowoneka ndi infrared spectral zigawo. Mayamwidwe ake ali mu 185-250 nm spectral dera, koma alibe mabandi mayamwidwe mu mawonekedwe owoneka ndi mawonekedwe owoneka bwino mu UV akuya ndi IR wavelength range. Ndiwo omwe amafunikira kutalika kwa kutalika kwambiri kuchokera ku DUV kupita ku MIR. Ndizokwera mtengo kwambiri kuposa Silicon komanso zotsika mtengo kuposa Calcium Fluoride kapena ZnS Multi-spectral grade.JGS3 ndi yofanana ndi opanga otsatirawa Heraeus Suprasil 300.
