在中国原材料采购网上，你能轻松找到哪些供应商提供金属丝网波纹填料(250AX 500BX 700CY)呢？这些填料以其高效的特性和广泛的应用而闻名，它们由若干平行直列的金属波纹网片排列组成，形成圆盘状。这种设计使它们拥有比表面积大、孔隙率大、重量轻；气相通路倾角小、有规则且压降低；径向扩散良好，气体接触充分。
金属丝网波纹填料是目前世界各国应用比较广泛的高效填料，其性能参数包括峰高（mm）、比表面积（m²/m³）、堆积重度（Kg/m³）、倾斜角度、空隙率（m³/m³）、每板压力降（Pa/n），HETP/mm以及理论板数(m-1）。不同型号如250AX、500BX和700CY具有不同的性能指标，如峰高为12mm、高于250mm，比表面积为125m²/m³等。
金属丝网波纹填料之所以受到青睐，是因为它具备多项优点：理论板数高，通量大，压力降低；负荷性能好，可以在较低负荷下保持较好的工作状态；操作弹性大，可以适应复杂操作条件；放大效应不明易，即便是在极端条件下也能保持稳定性能。此外，它还能够满足精密、大型、高真空精馏装置的要求，为难分离物系、热敏性物系及高纯度产品的精馏分离提供了有利条件。
metallic mesh wave filling material, the world is widely used in the high efficiency of the filler, it is composed of several parallel and perpendicular to the metal wave net plate arranged in a circular disc shape. It has a large surface area, high porosity rate, light weight; small angle of gas phase passage, regularity and low pressure drop; good radial diffusion and sufficient gas contact.
The performance parameters of metallic mesh wave filling material include peak height (mm), specific surface area (m2 / m3), bulk density (kg / m3), inclination angle, void ratio (m3 / m3), pressure drop per panel (Pa / n), HETP (/ mm) and theoretical number of panels per meter (-1). Different models such as 250AX, 500BX and 700CY have different performance indicators such as peak height over 12mm.
Metallic mesh wave filling material is so popular because it has many advantages: high theoretical number of panels with high flow rate and low pressure drop; good load performance that can maintain stability at relatively low loads; large operation elasticity suitable for complex operations; no obvious magnification effect maintaining stable performance even under extreme conditions. Additionally, it also meets the requirements for precise large-scale vacuum distillation devices providing favorable conditions for separating difficult-to-separate substances or heat-sensitive substances as well as products with high purity.
