各种活性炭特点以及吸附性能说明
作者:管理员    发布于:2014-08-12 08:09:51    文字:【】【】【
各种活性炭特点以及吸附性能说明,介绍下椰壳活性炭、果壳活性炭、粉状活性炭、柱状活性炭这四大类活性炭各自的特点。

  椰壳活性炭:具有机械强度高,孔隙结构发达,比表面积大,吸附速度快,吸附容量高,易于再生,经久耐用等特点。

  果壳活性炭:具有孔隙结构发达,比表面积大,吸附速度快,吸附容量高,易于再生,经久耐用特点

  粉状活性炭:具有比表面积大,活性高,微孔发达,脱色力强,孔隙结构较大等特点,孔隙结构大,能有较吸附液体中的颜色等较大的各种物质、杂质。

  柱状活性炭:具有强度高,吸附速度快,吸附容量高,比表面积较大,孔隙结构发达,孔隙大小在于椰壳活性炭和木质活性炭之间。
