Proces proizvodnje kvarcnih cijevi

Quartz tubing is a type of transparent or translucent tubing made from silicon dioxide (SiO2), known for its high temperature resistance, corrosion resistance, and high purity. Due to its excellent physical and chemical properties, quartz tubing finds widespread application in high-tech industries such as semiconductors, optical fibers, and photovoltaics. The manufacturing process of quartz tubing mainly includes the following steps:

The production of quartz tube requires high-purity quartz sand as a raw material. Initially, the quartz sand is sifted and cleaned to remove impurities and dust. Subsequently, the cleaned quartz sand is dried to facilitate further processing.

Osušeni kvarcni pijesak stavlja se u visokotemperaturnu peć i topi na temperaturama iznad 1700°C. Tokom procesa topljenja, kvarcni pijesak prelazi u rastopljeno stanje silicijum dioksida. Da bi se osiguralo efikasno topljenje, obično se koriste peći kao što su elektrolučne peći, otporne peći ili peći na plin.

Otopljeni silicijum dioksid se oblikuje u cijevi kroz posebne procese oblikovanja. Uobičajene metode uključuju izvlačenje, puhanje i centrifugalno oblikovanje. Metoda crtanja uključuje rastezanje rastopljenog silicijum dioksida u tanke cijevi; metoda puhanja uključuje puhanje rastopljenog silicijum dioksida u kalupe za formiranje cijevi; a centrifugalna metoda uključuje izlijevanje rastopljenog silicijum dioksida u rotirajuće kalupe, koristeći centrifugalnu silu da se oblikuje u cijevi.

Nakon formiranja, kvarcne cijevi se moraju ohladiti. Tokom procesa hlađenja mogu se razviti određena naprezanja na unutrašnjoj i vanjskoj površini kvarcnih cijevi. Da bi se smanjio uticaj naprezanja na performanse kvarcnih cevi, brzinu hlađenja treba kontrolisati unutar određenog opsega, obično 50-100°C na sat.

The cooled quartz tubes require cutting and grinding to meet the needs of different application scenarios. Cutting can be done using mechanical or laser cutting methods. The grinding process mainly involves treating the ends of the quartz tubes to enhance their flatness and smoothness.

Throughout the production process of quartz tubes, it is necessary to comprehensively inspect aspects such as the tubes’ size, density, transparency, and surface quality. These inspections include visual inspection, optical testing, and mechanical testing, aiming to ensure the quality of the quartz tubes meets requirements.

Finally, the quartz tubes are cleaned and packaged. During the cleaning process, it is necessary to remove impurities such as oil and dust from the surface of the quartz tubes. During packaging, it is important to ensure the quartz tubes are not subjected to external forces to avoid damage.

In summary, the production process of quartz tube includes stages such as material selection and preparation, melting, forming, cooling, cutting and grinding, inspection, and cleaning and packaging. Each stage requires strict control of process parameters to ensure the quality and performance of the quartz tubes.
