What is sublimation technology?

The process of thermal sublimation is highly unique: it first heats a solid material to a specific temperature, then applies pressure to transform the substance directly from a solid to a gas, bypassing the liquid phase entirely. This differs from the common phase transition process of substances (e.g., a solid melts into a liquid, which then evaporates into a gas). The application of thermal sublimation enables more efficient processing of solid substances and improves work efficiency.

Thermal sublimation technology offers numerous advantages. Firstly, it reduces energy loss, as no energy is consumed for liquid phase transition during the process. Secondly, it prevents substance loss during phase transition and increases material utilization. Additionally, it supports diversified applications such as high-speed separation, purity enhancement, and waste gas treatment.

In practical use, thermal sublimation holds broad potential across various fields. In the pharmaceutical industry, it can efficiently purify drugs to improve their purity and safety. In chemical processes, it is used for the preparation and separation of organic compounds, enhancing product quality. In environmental protection, it effectively treats waste gases containing pollutants to reduce environmental pollution. Moreover, it can be applied in materials science, the food industry, and other sectors.
