The columnar activated carbon adsorption process, the adsorbent and the adsorbate between adsorption, both physical adsorption, chemisorption there, the gas is more apparent. The physical columnar activated carbon adsorption: Is the interaction between the adsorbent and the adsorbent force of attraction between molecules caused by adsorption, known as physical adsorption. Columnar activated carbon is characterized by physical adsorption of the physical adsorption is weak intermolecular attraction. Heat of adsorption is small, and liquefied gas heat are similar, it is easier desorption (desorption). Columnar activated carbon chemical adsorption: sorbent mass attached to each other with the force of a chemical bond strength, caused by chemical adsorption called columnar activated carbon adsorption. Strong chemisorption, adsorption heat is large, similar to the chemical reaction, chemical adsorption monolayer adsorption, absorption rate is small, and with the increase of the temperature, generally at an elevated temperature; chemical adsorption is irreversible adsorption , adsorbents and pay suction section generates a chemical reaction mass to produce a new material. Procurement columnar activated carbon needs to pay attention to what the North Branch columnar activated carbon manufacturer customers and friends to introduce to you, what kind of columnar activated carbon of good quality, how to choose columnar activated carbon I think this should have been more concerned about our customers, we start with the columnar to introduce the three characteristics of activated carbon. A Look at the pore volume of more columnar activated carbon more crisp, relative density, there would be more light, so a good handle on the columnar activated carbon will be relatively light, good performance columnar columnar activated carbon than the bulky inferior lot. 2 See the handful of carbon bubbles into the water, penetration of the water, the water will gradually immersed in the pore structure of activated carbon column, forcing the air out of the pores, resulting in a series of very small bubbles in water, pulled out a small bubble line, while the bubbles will issue the slightest sound, the longer the duration, the more columnar activated carbon adsorption capacity is strong, but not all, to note that when the moisture content is large, see blisters This method is not accurately determine the columnar the size of the activated carbon adsorption capacity. 3 decolorization columnar activated carbon adsorption capacity is another manifestation of bleaching, columnar activated carbon with colored liquid can become pale or colorless magical ability, this is in fact because of columnar activated carbon adsorption colored liquid in the production of pigment molecules phenomenon. Columnar activated carbon variety, quality and low ranges, so we buy it to follow the columnar activated carbon method to buy. One to choose the right business, professional cast future Jinhao professional manufacturer of activated carbon, two, be careful not to buy offer below-market products. Three columnar activated carbon according to the characteristics to buy.
