Proizvodni proces kremenčevih cevi

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 kremenova cev 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.

Posušen kremenčev pesek damo v visokotemperaturno peč in talimo pri temperaturah nad 1700°C. Med procesom taljenja se kremenčev pesek spremeni v staljeno stanje silicijevega dioksida. Za zagotovitev učinkovitega taljenja se običajno uporabljajo peči, kot so elektroobločne peči, uporovne peči ali plinsko plamenske peči.

Staljeni silicijev dioksid se oblikuje v cevi s posebnimi postopki oblikovanja. Običajne metode vključujejo vlečenje, pihanje in centrifugalno oblikovanje. Metoda vlečenja vključuje raztezanje staljenega silicijevega dioksida v tanke cevi; metoda pihanja vključuje pihanje staljenega silicijevega dioksida v kalupe za oblikovanje cevi; centrifugalna metoda pa vključuje vlivanje staljenega silicijevega dioksida v vrteče se kalupe, pri čemer se z uporabo centrifugalne sile oblikuje v cevi.

Po oblikovanju je treba kremenčeve cevi ohladiti. Med procesom ohlajanja se lahko pojavijo določene napetosti na notranji in zunanji površini kremenčevih cevi. Da bi zmanjšali vpliv obremenitve na delovanje kvarčnih cevi, je treba hitrost hlajenja nadzorovati v določenem območju, običajno 50–100 °C na uro.

The cooled kremenčeve cevi 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 kremenčeve cevi, 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 kremenčeve cevi 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 kremenova cev 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.
