Сценарий применения
Avoid Impacts and Vibrations
Although U-shaped quartz tubes possess good hardness and strength, it’s important to avoid impacts and vibrations during use to prevent cracking or damage.
Control Temperature Appropriately
When operating U-shaped quartz tubes at high temperatures, carefully manage the temperature to prevent exceeding the maximum operating temperature, which can lead to deformation or damage.
Avoid Contact with Corrosive Substances
Minimize direct contact between U-shaped quartz tubes and corrosive substances like strong acids and alkalis to prevent corrosion and damage.
Regular Maintenance and Care
Perform regular inspections and maintenance on U-shaped quartz tubes, including cleaning surface contaminants and checking the heating element connections, to ensure proper function and extend their lifespan.
Quartz U-shaped tubes are commonly used in laboratory instruments, especially for conducting chemical or biological reactions. They consist of two U-shaped quartz tubes forming an inverted U-structure, providing a large reaction surface area and good mass transfer performance, enhancing reaction efficiency and rate.
Quartz U-shaped tubes can work continuously at 1200°C and even under 1500°C for short periods.
The manufacturing process mainly includes material selection and preparation, melting, forming, cooling, cutting and grinding, inspection, and cleaning and packaging.
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.
