Two-layered porous plates with combined properties
Tridelta Siperm has developed a two-layered porous material. Compared to our standard qualities, which show a homogeneous pore structure in the cross-section, the new material consists of two layers with different pore sizes. The sinter bridges which are formed between the two layers in the sintering process prevent that the layers loosen from each other when the material is cleaned with compressed air. In use the smoother side is facing the product in order to either achieve a maximum filter efficiency or – in the sphere of fluidization – to avoid the infiltration of the bulk into the fluidization unit. The product-averted side consists of a rougher, more permeable layer in order to hold the pressure drop as low as can.
