Technique:
This series of products selects high quality shell (coconut shell, peach shell, apricot shell) or wood bits as raw material. It adopts high-temperature steam activation technique. And it is developed through smashing, screening and refining.
Properties and uses:
This series of products have features of strong absorption capacity, fast filter speed, even particle size, small bed resistance, high wear resistance, washing resistance and long serve life.
It is widely applied in scientific research, chemical analysis, biological reagent, medical preparation, fine chemical industry for decoloration, purification, deodorization and recycling.
