Overview of high borosilicate glass tube
A high borosilicate glass tube is a high-performance glass material made of silicon dioxide (SiO₂) and boron oxide (B₂O₃) as the main components, supplemented by a small amount of aluminum oxide (Al₂O₃), alkali metal oxides (such as Na₂O, K₂O), and other raw materials. The production process includes raw material pretreatment, melting, molding, annealing, and post-processing. Among them, high-temperature melting technology (such as electric melting furnaces) can improve the uniformity and stability of the material. 35.
Core characteristics
Heat resistance and low expansion
The linear thermal expansion coefficient is as low as (3.3±0.1)×10⁻⁶/K, which can withstand high temperature changes (such as laboratory heating, solar heat collection) without breaking easily. 37.
Chemical stability
Resistant to acid and alkali corrosion (except hydrofluoric acid and hot phosphoric acid), suitable for harsh environments such as chemical pipelines and pharmaceutical packaging; the surface is smooth and non-porous, which can reduce material deposition and pollution. 57.
Optical and mechanical properties
High transmittance makes it easy to observe the experiment or production process; high strength and hardness make it suitable for making precision instruments and pressure-resistant equipment37.
Application areas
Laboratory and scientific research: used for chemical instruments, reaction vessels, and experimental consumables to meet the needs of high-temperature and high-purity experiments34.
Solar energy utilization: as the core material of vacuum collector tubes, it absorbs and converts solar energy to improve the efficiency of water heaters6.
Chemical and pharmaceutical: corrosion-resistant pipes, pharmaceutical containers, and food testing equipment to avoid heavy metal precipitation and chemical reactions57.
Industrial and civil: manufacturing craft glass products (such as tea sets, lamps), energy-saving lamps, etc., which are both functional and aesthetic37.
Production process optimization
Raw material processing: acid leaching and iron ion collectors (such as tannic acid/polyacrylamide hydrogel) are used to remove quartz sand impurities and improve transmittance1.
Coloring technology: Cobalt blue pigment is wrapped by mesoporous silica, combined with silane coupling agent and borate modification to achieve color stability at high temperature2.
Quality control: The company introduces a fully automatic electric melting furnace and online detection system to ensure product consistency and reliability
