Imibuzo ebuzwa kanengi

Q Ngiliphi izinga lokutjhisa eliphezulu lokusebenza kwengilazi ye-quartz ehlanganisiwe?

Ingilazi ye-quartz ehlanganisiwe ingajamelana namazinga womtjhiso wokusetjenziswa kwesikhathi esifitjhani ukuya ku-1300 °C kanye nokusetjenziswa kwesikhathi eside okuragelako okufika ku-1100 °C. Izinga lokutjhisa layo lokusebenza ngokutjhisa lisuka ku-1750 °C ukuya ku-2050 °C, okwenza bona ibe ngenye yezinto zengilazi ezijameleko khulu ezitholakalako.

Q Kubayini ingilazi ye-quartz ehlangeneko inezinga eliphasi kangaka lokunwebeka kokutjhisa?

I-thermal expansion coefficient ephasi khulu ye-5.5 × 10⁻7 cm/cm·°C ngumphumela wesakhiwo sayo se-asilicon dioxide (SiO2). Iphahla leli linikela i-quartz ehlanganisiweko ukujamelana nokutjhisa okukhethekileko, okwenza bona ikghone ukukghodlhelela amatjhuguluko womtjhiso msinyana ngaphandle kokuqhekeka.

Q Izinga le-PPM litjho ukuthini ngengilazi ye-quartz begodu kubayini iqakathekile?

Igreyidi ye-PPM (amalunga ngesigidi) itjho izinga lokusilaphazeka kwensimbi ngaphakathi kwengilazi ye-quartz. Itholakala ngamagreyidi alawulwako we-10, 20, kanye ne-100 PPM, amanani aphasi we-PPM atjengisa ukuhlanzeka okuphezulu, okuqakathekileko kuma-semiconductor, optical, kanye neensetjenziswa zebubulo ezinembileko lapho ukusilaphazeka kufanele kwehliswe khona.

Q Ngiziphi iindlela zobukhulu ezitholakalako zengilazi ye-quartz?

Ingilazi ye-quartz itholakala ngobukhulu obusuka ku-2 mm ukuya ku-20 mm. Ubujamo obuyindilinga kanye nobubanzi obubanzi bobukhulu kwenza bona isebenziseke khulu emabubulweni, elabhorethri, kanye neensetjenziswa zokubona.

Q Amandla wokucindezela we-quartz ehlanganisiweko aqhathaniswa njani namandla wayo wokugoba?

I-quartz ehlanganisiweko inamandla aphezulu khulu wokucindezela ayi-1100 MPa, okwenza bona ijame khulu namandla wokucindezela. Kodwana, amandla wayo wokugoba (wokugoba) aphasi khulu ku-67 MPa, okuyinto ejayelekileko yezinto zengilazi.
