Maksimalna radna temperatura kvarcnih cijevi u vakuumskim primjenama

Quartz tubes are a prevalent material known for their exceptional thermal stability and high-temperature resistance. Widely used in industrial vacuum equipment, their maximum operating temperature is a focal point of interest.

The maximum temperature at which a quartz tube can be used in a vacuum is influenced by several factors, including the material of the quartz tube, its wall thickness, the external environment temperature, and the vacuum level.

Firstly, the material of the quartz tube plays a decisive role in its high-temperature resistance. Made from high-purity silicon dioxide, quartz tubes exhibit excellent heat and corrosion resistance. Generally, the maximum operating temperature of a quartz tube can reach up to about 1200 degrees Celsius.

Debljina stijenke kvarcne cijevi također utječe na otpornost na visoke temperature. Kvarcne cijevi s tankim stijenkama sklone su lomovima zbog toplinskog naprezanja pod visokim temperaturama, dok deblje stijenke mogu bolje podnijeti toplinsko naprezanje u okruženjima s visokim temperaturama. Stoga odgovarajuću debljinu stijenke treba odabrati na temelju specifične radne temperature i okoline.

The external environment temperature is another factor affecting the maximum use temperature of quartz tubes. If the ambient temperature is too high, it can adversely affect the quartz tube’s temperature resistance. Hence, when using quartz tubes, it’s crucial to arrange cooling devices properly to ensure they operate within a suitable temperature range.

Razina vakuuma značajan je faktor koji utječe na maksimalnu radnu temperaturu. U uvjetima visokog vakuuma, toplinska vodljivost plina je loša, što usporava porast temperature u kvarcnim cijevima, što im omogućuje da izdrže više temperature. Nasuprot tome, u uvjetima niskog vakuuma, toplinska vodljivost plina je bolja, što dovodi do bržeg porasta temperature i niže maksimalne temperaturne tolerancije.

In summary, the maximum operating temperature of quartz tubes in vacuum applications is influenced by multiple factors. When selecting and using quartz tubes, it’s essential to consider material, wall thickness, external environmental temperature, and vacuum level to ensure stable operation within the appropriate temperature range. Furthermore, to enhance the high-temperature resistance of quartz tubes, measures like ceramic casing and cooling devices can be employed to reduce surface temperature and minimize thermal stress impact.
