Лабораторные и химические приложенияQuartz light guide rods utilize the principle of total internal reflection for transmitting light signals. When light travels from an optically dense medium to an optically less dense medium, if the angle of incidence is greater than or equal to the critical angle, the light will be totally reflected back into the original medium, thereby achieving light transmission. Within a quartz light guide rod, light undergoes continuous total internal reflection at the inner walls of the rod, thereby traveling along the length of the rod towards the target location.

There are two primary methods for producing quartz rods: the continuous method and the flame fusion method (also known as the gas fusion method).
Continuous Method: In this method, quartz sand is fed from the top into a furnace, which comprises a metallic quartz crucible surrounded by electric heating elements. The quartz sand melts at high temperatures. The molten material then passes through a shaping orifice at the bottom of the crucible, producing rods, tubes, sheets, or other various specified product forms.
Flame Fusion Method: This method involves using hydrogen and oxygen to melt colorless quartz crystal. The molten material is formed into quartz glass through the melting and congealing of crystalline particles in the flame. The quartz glass is then removed from the flame through different methods and processed into quartz rods of the desired shape.
Стойкость к высоким температурам
Quartz glass exhibits excellent high-temperature resistance, maintaining stability in high-temperature environments.
Low Thermal Expansion Coefficient
The thermal expansion coefficient of quartz glass is extremely low, ranging from 1/12 to 1/20 of that of ordinary glass, contributing to its stability under temperature variations.
Corrosion Resistance
Quartz glass is resistant to a variety of acids, bases, and salts, with the exception of hydrofluoric acid and hot phosphoric acid above 300 degrees Celsius.
High Light Transmission Rate
The light transmission rate can reach 99.9%, ensuring high transmittance of light signals during transmission.

Quartz light guide rods exhibit excellent long-term stability in various environments. They possess a high degree of chemical stability, allowing them to maintain their performance and integrity in a wide range of chemical environments. Additionally, the thermal expansion coefficient of quartz glass is among the lowest of common industrial glasses, which means that it maintains good dimensional stability during temperature changes and is highly resistant to thermal shock.
Quartz light guide rods possess extremely high chemical stability and are nearly unreactive with most acidic and alkaline substances, except for hydrofluoric acid. This corrosion resistance makes them invaluable in environments where frequent contact with corrosive materials is common.
Quartz stirring rods offer superior high-temperature resistance and chemical stability compared to plastic stirring rods. Additionally, they possess high structural strength, are less prone to breakage, and have a long service life.

Часто задаваемые вопросы
Кварцевое стекло - это твердый и хрупкий материал с отличными физическими и химическими свойствами, чрезвычайно высокой механической твердостью, хорошей электроизоляцией, высокой температурой и коррозионной стойкостью, низкой и стабильной задержкой, хорошим светопропусканием и т.д. Он широко используется в полупроводниках, оптике, электричестве, химии, аэрокосмической промышленности, автомобилестроении и других областях. Твердые и хрупкие материалы трудно поддаются обработке, поэтому во многих областях срочно требуются процессы резки с небольшим разрушением кромок, меньшими потерями материала, низкой шероховатостью поперечного сечения и широким диапазоном толщины реза. Традиционным методом резки кварцевого стекла является механическая резка, то есть резка кругом. К нетрадиционным методам резки относятся водоструйная резка, резка проволокой электрохимического разряда, непрерывная лазерная резка и т. д. Механическая резка имеет низкую стоимость, но контакт между кругом и материалом приводит к большому износу инструмента, а материал легко загрязняется инструментом. Кварцевое стекло подвержено разрушению кромок, микротрещинам и остаточному напряжению, что влияет на прочность и эксплуатационные характеристики материала! Трудно добиться криволинейной резки и требуется последующая обработка, такая как шлифовка и полировка. Лазерная резка не контактирует непосредственно с материалом, не имеет контактного напряжения и может выполнять сложную криволинейную резку. Пикосекундный лазер обладает такими преимуществами, как малый диаметр пятна, высокая точность, короткое время воздействия на материал и малая площадь воздействия, и подходит для обработки твердых и хрупких материалов.
