Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
referring to fig. 1-4, a method for preparing a low-pollution carbon felt in an environment-friendly manner comprises the following steps:
s1, loosening the compacted and intertwined polyacrylonitrile fiber raw material and removing impurities, so that the transverse connection scale of the fibers is reduced, and conditions are created for further loosening to a single state;
S2, carding the spinning raw materials which are processed primarily into a single fiber state, forming a net fiber thin layer, then gathering into fiber strips, removing many impurities and defects from the fiber strips which are carded, fully mixing fibers with different qualities and colors, and straightening the fibers primarily and having directionality;
S3, adopting a laying mode, namely laying several layers of fiber webs to meet the requirements of uniformity, width, weight and strength of the non-woven fabric product;
S4, repeatedly puncturing the fiber web by using a pre-needling machine to reinforce the fluffy fiber web, wherein the pre-needling machine not only has the main structure of the needling machine, but also has a reasonable fiber web feeding mechanism, so that the fluffy fiber web can easily enter a needling area along with the guiding of the feeding mechanism;
S5, repeatedly needling the pre-needled fiber web by using a main needling machine, wherein the needle density of the main needling machine is much higher than that of the pre-needling machine, the needling frequency is high, and the needle stroke is generally less than 5 mm;
s6, bonding the fiber web by using viscose to form a polyacrylonitrile felt, wherein polyacrylonitrile is a chemical substance and is obtained by free radical polymerization of monomer acrylonitrile, and the polyacrylonitrile fiber has the advantages of weather resistance, sun resistance and the like, can keep 77% of the original strength after being placed outdoors for 18 months, and is resistant to chemical reagents, particularly inorganic acid, bleaching powder, hydrogen peroxide and common organic reagents;
S7, removing natural impurities on the yarn or fabric, and pulp, auxiliaries and contaminants attached to the yarn or fabric in the spinning process by using a chemical reagent, wherein the chemical reagent is an activating agent, the activating agent is a type of regulating agent which can enhance the adsorption capacity of the mineral surface to a collecting agent in a flotation reagent, and is used for eliminating the action of an inhibitor by changing the chemical composition of the mineral surface, so that the mineral surface is easy to adsorb the collecting agent, and common activating agents comprise water, alcohol, acid, alkali and the like;
S8, dewatering the fiber web, and mechanically separating the porous substance and the water or liquid contained in the accumulated particle layer to avoid the water and the liquid remaining in the fiber web;
s9, converting protofilaments in the polyacrylonitrile fibers into a pyridine ring trapezoidal structure which is thermally stable and has a semiconductor resistance value;
s10, performing activation treatment on polyacrylonitrile fibers by using water vapor, wherein collisions capable of generating chemical reactions are called effective collisions, molecules generating the effective collisions are called activated molecules, and the activation process is a process of adding a catalyst in the chemical reactions to increase the activated molecules in the whole chemical reactions and reduce the activation energy.
s11, measuring, checking and testing the performance in the inspection project, and determining whether the performance meets the standard or not and whether the quality of the activated carbon fiber felt can be determined or not through the measurement, the check and the test;

In the present invention: as shown in fig. 2, under the condition that other conditions are not changed, the activation temperature is only changed, the influence of the activation temperature on the adsorption performance and yield of the activated carbon fiber is observed, and as the activation temperature rises, the iodine adsorption value increases within a certain range, and then increases slowly to a certain extent, because the specific surface area gradually increases with the rise of the activation temperature, so that the adsorption capacity of the activated carbon fiber is enhanced, but the specific surface area decreases after increasing to a certain extent, because the reaction is too violent due to too high temperature, the formed micropores are destroyed, so that the specific surface area decreases, and therefore, the activation temperature is not higher, and the better.
in the present invention: as can be seen from fig. 3, the longer the activation time is, the better the adsorption performance of the activated carbon fiber is, and the lower the yield is, under the same conditions, because the activation time is prolonged, the activating agent and the carbon atoms continuously perform chemical reaction, and various generated byproducts continuously escape, leaving voids on the surface of the fiber, and it can also be seen that the iodine adsorption value is increased rapidly at first.
In the present invention: as can be seen from fig. 4: the reaction speed component is increased along with the increase of the concentration of the activating agent, so that the specific surface area component of the activated carbon fiber is gradually increased, and the first-time capacity is enhanced.
In summary, the following steps: the strength of the adsorption capacity of the activated carbon fiber is changed along with the change of the activation time, the activation temperature and the activation metering fraction.
