activated Carbon Fiber (ACF), also known as fibrous activated carbon, is a highly efficient activated adsorbent material and an environmentally friendly engineering material with superior performance to activated carbon. The activated carbon fiber is a combination of "ultrafine particles, irregular surface structure and extremely narrow space", and has a diameter of 10 to 30 μm. The pores are directly opened on the surface of the fiber, the ultrafine particles are combined together in various modes to form abundant nanometer spaces, and the size of the formed spaces and the size of the ultrafine particles are in the same order of magnitude, so that a larger specific surface area is created. The micro-structure has a plurality of irregular structures, namely a heterocyclic structure or a micro-structure containing surface functional groups, has extremely large surface energy, and also creates a strong molecular field formed by the combined action of micropores and pore wall molecules, thereby providing a high-pressure system for the physical and chemical changes of adsorbed molecules. The diffusion path of the adsorbate to the adsorption site is short, the driving force is large, and the pore size distribution is concentrated, which is the main reason for the ACF to have large specific surface area, fast adsorption and desorption rate and high adsorption efficiency compared with the activated carbon.
Beeswax (Beeswax) is secreted from the abdomen of bees and is a material for nest building of bees, wax ester (Triacontanyl palmitate) is a main component thereof, and the chemical structure is as follows: CH (CH)3(CH2)29O-CO-(CH2)14CH3The molecular weight of the wax ester is larger, the space structure of the wax ester is like a long hairpin, and the existence of double bonds enables the polymerization of the hairpin to be staggered and overlapped, thus being easy to form a three-dimensional network structure framework configuration; the beeswax oil drops containing a large amount of active ingredients can freely pass through the frame, and gaseous pollutants and lipid pollutants are easily adhered by the oil drops in the frame.
The bactericidal performance of chlorine dioxide lies in that it can release nascent oxygen and hypochlorous acid molecule when it is contacted with microbe, and has good adsorptivity and penetrability for microbial cell, and can effectively oxidize the enzyme containing nitrogen base in cell, destroy enzyme system, at the same time make amino acid in protein be oxidated and decomposed, and quickly control microbial protein synthesis so as to attain the effect of inhibiting growth of bacteria or killing bacteria, and has good killing action for spore, virus, algae, fungi, iron blood bacteria and sulfate reducing bacteria, etc. and has no influence on higher animal cell structure. The deodorization mechanism of the chlorine dioxide is that the chlorine dioxide has strong oxidizability, can generate oxidation reduction reaction with a plurality of organic matters and inorganic matters in the air, including organic sulfides, organic amines, phenols, aromatic hydrocarbons, unsaturated compounds and the like, and achieves the purposes of decomposing peculiar smell and purifying the air; however, chlorine dioxide is chemically active and not very stable.
In the invention, the chlorine dioxide and sodium chlorate slow release composite material is prepared by coating beeswax on activated carbon fiber, and the activated carbon fiber is loaded with chlorine dioxide and sodium chlorate; the active carbon fiber has great surface energy through containing a plurality of irregular structures, namely heterocyclic structures or microstructures containing surface functional groups, provides a high-pressure system with physical and chemical changes of adsorbed molecules, coats chlorine dioxide and sodium chlorate, adsorbs strong oxidants of chlorine dioxide and sodium chlorate, and slowly releases chlorine dioxide and sodium chlorate; in addition, the beeswax is used for coating the activated carbon fiber, nitrogen-containing pollutants in the air are efficiently adsorbed by utilizing the three-dimensional net-shaped structure frame configuration of the beeswax, and then the activated carbon fiber slowly releases chlorine dioxide and sodium chlorate oxidized pollutants, so that the pollutants are removed.
