| 活性炭净化空气的原理是靠依靠其炭自身发达的孔隙结构和表面积，可以很大程度的接触到周围空气，被动吸附一些污染物到自己的孔隙中，所以说活性炭的表面越大、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，甲醛的分子JDG金属穿线管 不锈钢链板 隔离墩模具 检查井钢模具 流水槽模具 阶梯护坡模具 护坡砖模具 遮板模具 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 |
