你知道吗，化工产品中有这样一种叫做金属丝网波纹填料，它在世界各国都非常常见呢！这种填料是由许多平行的金属波纹网片排列成的圆形物体。它有很多好处，比如表面积大、孔隙率高、重量轻；气流通道倾斜角度小，有规则，压降低；气体扩散很好，气体与物质接触充分等特点。
metallic mesh wave filling material is widely used in the world, it is a circular disk shaped filler composed of many parallel metallic wave net plates. It has big surface area, high porosity rate, light weight; small angle of gas flow passage, regular and low pressure drop; good radial diffusion and sufficient contact between gas and solid.

Advantages
Metallic mesh filling material is widely used in the world for its high efficiency filler, mainly because:
Theoretical number plate is high with large flux and low pressure drop;
Good load performance with theoretical number plate increasing as gas load decreases without obvious lower limit;
Good operational elasticity;
No amplification effect.
It can meet the requirements for precision large-scale vacuum distillation devices.
It provides favorable conditions for separating difficult to separate materials or heat sensitive materials as well as producing highly pure products.
Applications
• AX-250: For precise distillation with strong intensity and fewer theoretical number plates.
• BX-500: For vacuum distillation under pressure less than7KPa especially heat sensitivity or difficult to separate binary systems.
• CY-700: For separation of isotopic mixtures or constitutional mixtures.
This article introduces you to the metal mesh wave filling material that is commonly used worldwide due to its efficiency and advantages such as large surface area, high porosity rate, lightweight structure along with other features like easy radial diffusion process making it suitable for various applications such as separating difficult substances or producing highly pure products.
