Proses Pengeluaran Tiub Kuarza

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.

Pasir kuarza kering diletakkan di dalam relau suhu tinggi dan dicairkan pada suhu melebihi 1700°C. Semasa proses lebur, pasir kuarza berubah menjadi keadaan cair silikon dioksida. Untuk memastikan pencairan yang berkesan, relau seperti relau arka elektrik, relau rintangan atau relau nyalaan gas biasanya digunakan.

Silikon dioksida cair dibentuk menjadi tiub melalui proses pembentukan khas. Kaedah biasa termasuk melukis, meniup, dan membentuk emparan. Kaedah lukisan melibatkan regangan silikon dioksida cair ke dalam tiub nipis; kaedah meniup melibatkan meniup silikon dioksida cair ke dalam acuan untuk membentuk tiub; dan kaedah emparan melibatkan penuangan silikon dioksida cair ke dalam acuan berputar, menggunakan daya emparan untuk membentuknya ke dalam tiub.

Selepas membentuk, tiub kuarza perlu disejukkan. Semasa proses penyejukan, tegasan tertentu boleh berkembang pada permukaan dalam dan luar tiub kuarza. Untuk meminimumkan kesan tegasan ke atas prestasi tiub kuarza, kadar penyejukan hendaklah dikawal dalam julat tertentu, biasanya 50-100°C sejam.

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.
