Buy 30 Ppi Filter Foam which indicates the number of inches per inch. The higher the ppi value in the filter plate, the more holes per inch, the smaller the holes, and the better the filtration effect.
Buy 30 Ppi Filter Foam but if the hole is too small, then the aluminum alloy will not pass the fluidity limit, so you should choose the right model.
30 Ppi Filter Foam is formed by high-temperature sintering to form interconnected open pores with its outer surface and its interior.
When the fluid passes through the microporous channel, suspended matter, colloidal particles, and macromolecular organic matter are trapped on the surface of the product, and the fluid passes through the microporous channel to generate various physical and chemical effects to purify and filter.
30 Ppi Filter Foam is important in the quality of the smelted aluminum melt, which greatly affects the subsequent processing properties and quality of the final product.
Therefore, all countries in the world attach great importance to the purification of aluminum melt.
There are many reasons for aluminum pollution.
