As industries such as new energy, electronic materials, advanced composites, and fine chemicals grow rapidly, advanced material production requires increasingly precise control of temperature, pressure, and the gas environment. In many advanced material production processes, a stable, continuous negative-pressure environment affects not only production efficiency but also product consistency and yield.

    In the production of EPS (expandable polystyrene), water ring vacuum pumps are mainly used to create vacuum, stabilize foaming pressure, and facilitate the removal of gases and vapors from the material. They are typical vacuum equipment on EPS production lines and are particularly suitable for operating conditions involving water vapor, moisture, dust, or small amounts of condensable gases.

In modified-plastics manufacturing, stable vacuum pressure is critical to finished-product quality. During melt extrusion, modified-plastics feedstock can easily entrain air and residual moisture. If these are not removed promptly, defects such as bubbles, pitting and crystalline spots may appear on the sheet surface, severely affecting flatness and transparency and substantially reducing the yield of conforming products. FORYOU specializes in vacuum-technology R&D. Its centralized vacuum system addresses these challenges while also providing intelligent variable-frequency operation, zero wastewater discharge and energy-saving performance.

In saltworks, vacuum pumps are primarily used in vacuum-evaporation salt production. By reducing the pressure inside the evaporator, they enable brine (an aqueous NaCl solution) to boil and evaporate at a lower temperature. This reduces energy consumption, improves evaporation efficiency, and promotes salt crystallization. Vacuum evaporation is one of the principal technologies used in modern industrial salt production.

Water ring vacuum pumps provide the vacuum conditions that make concentration and evaporation processes more efficient, controllable and gentle on heat-sensitive products. Designed for demanding process environments, they continuously remove non-condensable gases and vapor loads so evaporators can operate at the intended pressure and temperature.

Application of Dry Screw Vacuum Pumps in Organic Solvent Distillation: An Efficient Vacuum Solution for the Chemical and Pharmaceutical Industries
In chemical, pharmaceutical, fine chemical, and advanced materials manufacturing, organic solvent distillation is a critical process. Whether producing API raw materials, intermediates, catalysts, or fine chemicals, a stable vacuum system directly affects distillation speed, product purity, solvent recovery rate, and overall production efficiency.
