椰壳活性炭与煤质活性炭:如何选择最适合您的产品?

原料与制造工艺

椰壳活性炭采用优质椰壳为原料,经400-500°C炭化后,在900-1100°C下通过蒸汽活化。产品以微孔为主,非常适合吸附小分子物质。

煤质活性炭以烟煤或无烟煤为原料,经炭化和活化制得。产品孔径分布较宽,含有较多的中孔和大孔。

关键性能参数对比

参数 椰壳活性炭 煤质活性炭
碘值(mg/g) 900-1200 800-1050
糖蜜值 150-250 200-400
硬度(%) 95-99 70-90
灰分(%) 3-5 8-15
比表面积(m²/g) 900-1200 800-1100

孔径结构差异

椰壳炭以微孔为主(占85-95%),对氯气、VOCs、THMs等小分子物质吸附效果极佳。煤质炭具有更多中孔(20-40%),对大分子有机物、色度和腐殖质去除效果更好。

硬度与使用寿命

椰壳炭硬度(95-99%)远高于煤质炭(70-90%),意味着:年损耗率5-10%(椰壳)vs 10-20%(煤质)、出水更清洁(碳粉更少)、床层压降更稳定。
