I. Introduction
Glass products play a crucial role in daily life and industrial production. With the continuous advancement of technology, various new types of glass materials have emerged. High borosilicate glass, a special type of glass with outstanding performance, has gained significant attention in the glass cup manufacturing industry in recent years. Its unique properties make it stand out in many applications, not only meeting the functional requirements of cups but also enhancing the user experience. A thorough study of the characteristics, application areas, and advantages of high borosilicate glass cups can help better leverage their value and promote the development of related industries.
2. Characteristics of high borosilicate glass
2.1 Low coefficient of expansion
The thermal expansion coefficient of high borosilicate glass is extremely low, typically around (3.3±0.1) × 10⁻⁶/K. This characteristic allows high borosilicate glass cups to withstand extreme temperature changes. For example, when a high borosilicate glass cup taken directly from the refrigerator is poured into boiling water, it will not crack due to the sudden temperature change, capable of withstanding an instantaneous temperature difference of about 150℃. In contrast, ordinary glass has a higher thermal expansion coefficient and is prone to stress cracks or even cracking when subjected to similar temperature shocks. The low thermal expansion coefficient of high borosilicate glass cups provides excellent thermal stability, allowing them to maintain structural integrity in environments with frequent temperature fluctuations.
2.2 Good chemical stability
High borosilicate glass boasts excellent chemical stability. The boron oxide and other components in its chemical composition provide strong resistance to acids, alkalis, and other chemicals. When used for beverages, whether acidic juices, carbonated drinks, or alkaline tea, high borosilicate glass cups will not react chemically with these substances, ensuring that the quality of the beverages remains unaffected and no harmful substances are released. This chemical stability makes high borosilicate glass cups an ideal choice for food-grade safety standards, making them safe for use in food contact applications.
2.3 Higher mechanical strength
The structure of high borosilicate glass provides it with high mechanical strength. The tightly packed and orderly atomic arrangement within the glass enhances its impact resistance and wear resistance. In daily use, high borosilicate glass cups are more resistant to collisions and scratches compared to ordinary glass cups, making them less likely to develop scratches. Even when frequently used and moved, these cups can maintain their appearance and performance over time, thus extending their lifespan.
2.4 Excellent optical performance
High borosilicate glass excels in optics, characterized by high light transmission and low dispersion. The resulting glass cups are crystal clear, with a texture similar to that of crystal, clearly displaying the color and state of the beverage. Whether it’s for serving brightly colored fruit juices or clear tea, the walls of high borosilicate glass cups provide an excellent visual effect, enhancing the drink’s appeal and aesthetic value.
