Produktionsprocessen for kvartsrør

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 Kvartsrør 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.

Det tørrede kvartssand anbringes i en højtemperaturovn og smeltes ved temperaturer over 1700°C. Under smeltningsprocessen omdannes kvartssandet til en smeltet tilstand af siliciumdioxid. For at sikre effektiv smeltning anvendes typisk ovne som lysbueovne, modstandsovne eller gasflammeovne.

Den smeltede siliciumdioxid formes til rør gennem specielle formningsprocesser. Almindelige metoder omfatter trækning, blæsning og centrifugalformning. Tegnemetoden involverer at strække det smeltede siliciumdioxid til tynde rør; blæsemetoden involverer at blæse det smeltede siliciumdioxid i forme for at danne rør; og centrifugalmetoden involverer at hælde den smeltede siliciumdioxid i roterende forme, ved at bruge centrifugalkraft til at forme den til rør.

Efter formning skal kvartsrørene afkøles. Under afkølingsprocessen kan der udvikles visse spændinger på de indre og ydre overflader af kvartsrørene. For at minimere påvirkningen af stress på ydeevnen af kvartsrørene bør afkølingshastigheden kontrolleres inden for et specifikt område, typisk 50-100°C i timen.

The cooled Kvartsrør 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 Kvartsrør, 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 Kvartsrør 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 Kvartsrør 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.
