Kvartstorude tootmisprotsess

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 kvartstoru 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.

Kuivatatud kvartsliiv asetatakse kõrge temperatuuriga ahju ja sulatatakse temperatuuril üle 1700°C. Sulamisprotsessi käigus muutub kvartsliiv sulaks ränidioksiidiks. Tõhusa sulatamise tagamiseks kasutatakse tavaliselt selliseid ahjusid nagu elektrikaarahjud, takistusahjud või gaasileegi ahjud.

Sula ränidioksiid vormitakse spetsiaalsete vormimisprotsesside abil torudeks. Levinud meetodid hõlmavad tõmbamist, puhumist ja tsentrifugaalvormimist. Tõmbamismeetod hõlmab sula ränidioksiidi venitamist õhukesteks torudeks; puhumismeetod hõlmab sula ränidioksiidi puhumist torude moodustamiseks vormidesse; ja tsentrifugaalmeetod hõlmab sula ränidioksiidi valamist pöörlevatesse vormidesse, kasutades tsentrifugaaljõudu, et vormida see torudeks.

Pärast vormimist tuleb kvartstorusid jahutada. Jahutusprotsessi käigus võivad kvartstorude sise- ja välispindadele tekkida teatud pinged. Et minimeerida pinge mõju kvartstorude jõudlusele, tuleks jahutuskiirust reguleerida kindlas vahemikus, tavaliselt 50–100 °C tunnis.

The cooled kvartstorud 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 kvartstorud, 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 kvartstorud 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 kvartstoru 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.
