1. Dissolution method wood powdery charcoal
Dissolve the solid particles into an aqueous solution of 1‰--5‰ concentration before use, so as to quickly exert its effectiveness. When adding the medicine, it should adopt the method of gradually taking the medicine, slowly cast it in the water, and evenly in the water. Disperse, dissolve.
2. Adding wood powdery charcoal to the solution
Usually, an aqueous solution of about 0.5 ‰ -1 Torr is added. However, in the case of a high concentration and a high viscosity of the suspension, it is recommended to further dilute the aqueous solution to 0.1 Torr, and it is easy to mix and exert a sufficient effect.
3. The molecular weight is low and the viscosity is also weaker than the anion. Therefore, the cation and nonionic ratio concentration standards are slightly higher than the anion. (Depending on the situation, the concentration can be adjusted according to the water concentration. The concentration is high, the concentration is low. Turbidity. Low can be increased by appropriate concentration.) The recommended concentration is 5‰-1%.
1. When preparing polyacrylamide aqueous solution, it should be carried out in enamel, galvanized, aluminum or plastic drum. It should not be prepared and stored in iron container.
2. When dissolving, care should be taken to slowly and evenly add the product to the dissolver with stirring and heating measures. Avoid solidification, prepare the solution at a suitable temperature, and avoid mechanical shearing for a long time. The stirrer is 60-200 rpm, otherwise it will cause degradation of the polymer and affect the use effect.
3. The polyacrylamide aqueous solution should be ready for use. When the solution is left for a long time, its performance will gradually decrease depending on the water quality.
4. After adding the aqueous flocculant solution to the suspension, if it is stirred vigorously for a long time, the already formed flocs will be destroyed.
The outstanding performance of powdered activated carbon in the food industry:
The application of powdered activated carbon in the food industry is endless. The coconut shell activated carbon activated carbon for beverage and food is very popular in the market. The main application of Gongyi Jinhao Activated Carbon Factory in the purification of food industry, Jinhao activated carbon manufacturers can provide safe and economical solutions.
Alcoholic beverage
Alcohol, beer, liquor, whiskey, rum and vodka are decolorized with coconut shell activated carbon, turbidity is improved during aging, and some substances that affect the quality of the wine, such as higher alcohols (hydrooleanol), are described in detail. The application of activated carbon in alcohol. The mycotoxin and the storage of mycotoxin A appear in the wine, and the products of Jinhao Activated Carbon Factory are also needed to comply with relevant regulations. For wineries with low usage and high dust requirements, Jinhao powdered activated carbon special activated carbon series products can also be used. The product is a water-soluble granulated product that is easy to put into the treatment tank.
Sucrose refining
For sucrose refining, coconut shell activated carbon and shell activated carbon can be used, which can be used for decolorization before sucrose pulp is crystallized into white granulated sugar. On the one hand, activated carbon can adsorb plant pigments from sugar cane, and can also absorb colors produced by the production process (such as melanoids and caramel).
Powdered activated carbon can be used for large-scale production and then thermally regenerated. The application of granular activated carbon is flexible and can be used to treat sucrose raw materials due to the uneven quality from different origins and the conditions under which the scouring process must be adjusted.
Natural glycerin
Shell activated carbon and coconut shell activated carbon are used to purify natural glycerin, which is derived from high pressure cracking and vinegar transfer of edible oils and fats or biodiesel. Refined glycerin is used as a food additive to prevent food from cracking or to prevent food phase changes due to dry cracking. This property improves the softness of the food and the chewiness of the confectionery. Powdered activated carbon is used to remove organic impurities such as colored substances and some substances that cause isoindoles from glycerin.
Biochemical food
Coconut shell activated carbon and shell activated carbon can adsorb syrup pigments. The sources of these pigments are citric acid, lactic acid and other biochemical foods. Powdered activated carbon can also be used to increase biochemical conversion efficiency during fermentation. For the final product purification of lactate and gluconate, ultra-high purity activated carbon products meet the most stringent purification requirements.
Interpretation of the average skill of coconut shell activated carbon
When the coconut shell activated carbon is close to the adsorbent molecules on the surface of the adsorbent, or when the adsorbate molecules are close to each other, one molecule or an atom on the surface, even if it is non-polar, will be instantaneous. The asymmetry of the electron distribution is caused to form a partial electrode, and the atom or molecule corresponding thereto is induced to generate a partial electrode. At the two sub-electrodes, a weak electrical interaction force is generated. If the average value of the time is taken, a very weak gravitational force occurs at the atom or the molecule, which is the distraction force.
Coconut shell activated carbon When the distance between atoms is r, the force is roughly proportional to r_6. The more the number of extranuclear electrons H of an atom, the greater the polarization of an atom (that is, the atom with a large atomic number and a large atomic number). Further, when the distance between the adsorbed molecules of the surface is close, the dispersive force between the adsorbing molecules contributes to the adsorption force. On the other hand, when the distance between atoms or molecules becomes less than 7SV, a strong repulsion acts because the kinetic energy of the nucleus increases. Therefore, they can only be close to each other until a certain distance. The sum of the repulsive force and the dispersion of Lunjiao becomes the potential energy between molecules, and its size depends on the type of material and the electronic structure.
In addition to the interaction of the coconut shell activated carbon, another weak interaction is the interaction of the dipole. When the surface is negatively charged (electron affinity), the atomic chemistry is different. The distribution of electrons is biased. A party with a large negative charge. Let the offset power be + q, -q, the distance between them is r', and the electric moment p = gr' is presented between the atoms that are combined with each other, which is called the electric moment. Gravity occurs between a surface atomic group having such a gauge or a polar surface functional group and a molecule having a dipole. This gravitational force is slightly stronger than that of the third member. Moreover, when either of the adsorbate molecules or the surface of the gettering agent has a galvanic moment, a galvanic moment is induced on the other side close to it, thereby exhibiting a weak interaction proportional to rs.
