| 活性炭的表面越大、孔径结构越发达吸附能力就越强。另外活性炭的孔径大小与能吸附什么分子量大小的一定关系，理论研究证明有害物质的分子量越大，越容易被活性炭吸附，如苯的分子量是78框格护坡模具 箱体护坡模具 华尔街铜牛 电阻柜 接地电阻柜 电缆保护接地箱 隔离墩模具 化粪池模具，甲醛的分子量是30，活性炭吸附苯的能力要比吸附甲醛的能力强，所以工业生产中活性炭多用于苯系物的吸附剂使用。 The principle of air purification by activated carbon is to rely on its own developed pore structure and surface area, which can contact the surrounding air to a large extent, and passively adsorb some pollutants into its own pores, so the larger the surface of activated carbon, the more developed the pore structure, the stronger the adsorption capacity. In addition, there is a certain relationship between the pore size of the activated carbon and the molecular weight that can be adsorbed. Theoretical research shows that the larger the molecular weight of harmful substances is, the easier it is to be adsorbed by the activated carbon. For example, the molecular weight of benzene is 78, the molecular weight of formaldehyde is 30, and the ability of the activated carbon to adsorb benzene is stronger than that of formaldehyde. Therefore, the activated carbon in industrial production is mostly used as the adsorbent of benzene series |
