Maksimalna radna temperatura kvarcnih cijevi u vakuumskim aplikacijama

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 utiče na njenu otpornost na visoke temperature. Tankozidne kvarcne cijevi sklone su lomovima toplinskog naprezanja pod visokim temperaturama, dok deblji zidovi mogu bolje izdržati termičko opterećenje u okruženjima s visokim temperaturama. Stoga, odgovarajuću debljinu zida treba odabrati na osnovu 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.

Nivo vakuuma je značajan faktor koji utiče na maksimalnu radnu temperaturu. U uslovima visokog vakuuma, toplotna provodljivost gasa je loša, što usporava porast temperature u kvarcnim cevima, omogućavajući im da izdrže više temperature. Nasuprot tome, u uslovima niskog vakuuma, toplotna provodljivost gasa je bolja, što dovodi do bržeg porasta temperature i niže tolerancije maksimalne temperature.

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.
