FAQ
Q1: Ko quartz bell jar inogona kushandiswa ne hydrofluoric acid (HF)?
A1: Kwete. HF inopindirana neSiO2 kuumba silicon tetrafluoride (SiF₄), inokonzera kukanganisa kusingagadziriswi. Shandisa PTFE kana fluoroplastic chamber yeHF-ine maitiro.
Q2: Ko quartz bell jar inogona kuiswa chisimbiso pasi pevurumu yakakwirira here?
A2: Hongu, kana akabatanidzwa nemagaskets anoenderana (eg, copper yeultra-high vacuum, Viton yepasi/yepakati vacuum) nemaflanges (ISO-CF ye10⁻¹⁰ mbar, ISO{6}KF ye10⁻⁶ mbar). Ita shuwa kuti nzvimbo dzekuvharira dzakachena uye hadzina mavanga.
Q3: Ko iyo quartz zvinhu inovhara UV mwenje?
A3: Kwete-quartz inoendesa UV chiedza kudzika kusvika 200nm, zvichiita kuti ive yakanakira UV-maapplication anonzwa. Kune UV-zvinodiwa zvekuvharisa, quartz yakavharidzirwa kana zvimwe zvinhu zviripo (batita nesu kuti tiwane mhinduro).
Q4: Ndinogona kuchera makomba kana kuwedzera zviteshi kune quartz bell jar?
A4: Ehe, kuburikidza nemachini chaiwo nefekitori yedu. Rondedzera saizi yechiteshi, nzvimbo, uye mhando (kupinza gasi, kudyisa magetsi, nzvimbo yekuona) panguva yekugadzirisa kuti ive nechokwadi chekuvimbika kwechimiro uye kusapinda kwemhepo.
