PINGXIANG XINQUAN QUÍMICA PACKING CO., LIMITADO. 
El filtro de espuma cerámica de alúmina marca Xinquan se utiliza principalmente para filtrar aluminio y aleaciones de aluminio en fundiciones y fundiciones.. Debido a su excelente resistencia a la corrosión y resistencia a la corrosión del aluminio fundido., it can effectively remove inclusions, reduce trapped gas and provide laminar flow, thus making the filtered metal cleaner. Cleaner metal can produce higher quality castings, less scrap and fewer inclusion defects, thereby reducing costs and increasing profits.
Common sizes: 7 “, 9”, 12 “, 15”, 17 “, 20” y 23 “.
We offer PPI 10 to PPI 60 (PPI=per inch of pore), or we can customize the size.
