The activated carbon package has a good effect on removing formaldehyde. It is manufactured through a series of processes such as crushing, sieving, catalyst activation, rinsing, drying, and screening through physical and chemical methods. The function of the activated carbon package is mainly used to adsorb harmful gases such as formaldehyde, filter out insoluble, and adsorb some soluble substances. Next Xiaobian introduced to everyone how to use activated carbon and activated carbon package purchase methods.
How to use activated carbon package
1. Clean and remove dust before use, otherwise these black dust may temporarily affect the cleanliness of water quality. However, it is advisable not to rinse directly with fresh tap water, because the pores of activated charcoal will absorb chlorine and bleaching powder in tap water and damage the water quality when it is placed in the filter.
2. By simple and simple cleaning, it is impossible to clean the impurities in the pores of the activated carbon. Therefore, it is important to replace the activated carbon on a regular basis so that the activated carbon loses its efficacy due to "saturated adsorption." And the timing of the replacement is best not to wait for it to expire before it is replaced, so as to ensure that the activated carbon can continuously remove the harmful substances in the aquarium water quality, it is recommended to replace the activated carbon 1-2 times a month.
3. The efficiency of treatment of activated carbon is related to its treatment amount. Usually, the effect of “multiple treated water quality is relatively goodâ€.
4. After the quantitative activated carbon coating is used, the changes in water quality should always be observed during the initial period of use, and the observed results should be taken as a basis for determining how long it takes for activated carbon to fail and replace.
5, in the use of drugs for the treatment of fish diseases, you should temporarily remove the activated carbon, suspended use. In order to avoid the drug being adsorbed by activated carbon, the therapeutic effect is reduced.
Activated carbon package purchase method
1, see the density of activated carbon
The more active carbon pores, the higher the adsorption performance, the more crisp the activated carbon, the lower the relative density, and the lighter the hand feel, and the larger the volume in the case of equal weight packaging. It is recommended to purchase activated carbon products with low density, light hand feel, and large weight.
2, see the size of activated carbon particles
The smaller the activated carbon particles are, the larger the contact air area, the larger the specific surface area and the better the adsorption performance. However, the smaller the particles, the greater the loss during the crushing process, the more dust, and the higher the cost. Many manufacturers use large-particle activated carbon to reduce costs. Of course, the performance is not good. Generally, the activated carbon with a particle size of about 0.5 mm achieves the best performance and ensures that it is not a powder and has no pollution. It is recommended to choose an activated carbon product with a particle diameter of 0.42-0.85 mm.
3, look at active carbon components
Activated carbon depends on the pore size to adsorb harmful gases. The molecular weights of different harmful gases are different, and the particle size is also different. Activated carbon pores need to be adsorbed between 0.45 and 2 nanometers to adsorb formaldehyde and other toxic gases. Internationally, coconut shell charcoal absorbs odors and stupidity. The preferred activated carbon, such as pollution, is the most ideal formaldehyde adsorbing carbon. It is recommended to purchase a comprehensive adsorption product composed of coconut shell activated carbon and gas phase microporous activated carbon. The coconut shell is not necessarily the best, it must match the pore size of the harmful gas molecules.
4, see the company
Professional activated carbon production companies, manufacturers direct production, technical quality is only perfect, the cost is not high, cost is good, the market for inferior activated carbon manufacturers, mostly trading companies, more building materials city production of activated carbon, these brand manufacturers simply have no production capacity There is no product standard or enterprise standard. The quality can be imagined. It is recommended to choose products produced by professional activated carbon production companies.
5, look at the packaging
The outer packaging of activated carbon must be sealed, otherwise it will fail at a point of contact with the air at the point of sale, and it will have failed after it has not been used. It is recommended to choose a completely sealed product.
6, see bubbles
Put a small amount of activated carbon into the water, because the water molecules are small, the water will gradually dip into the pore structure of the activated carbon, forcing the air in the pores to discharge, resulting in a series of extremely small bubbles, pulling a small bubble line in the water, at the same time The sound of bubbles in the filaments, the better the performance, the more severe the phenomenon of activated carbon. The longer the time.
7, see ingredients
On the market, inferior products, multi-sampling industrial cylindrical coal-based activated carbon, or large-grained shell carbons with a particle diameter of more than 2 mm, or granular bamboo charcoal, are not commercial vapor-phase adsorptive activated carbons. It is recommended to purchase small particles (particles with a diameter of about 0.5 mm) for professional gas phase adsorption of coconut shell charcoal and spherical microporous activated carbon.
8, see if it is charcoal material
Carbonized materials are carbons that have not undergone an activation process only after the carbonization process, and are not true activated carbons. The activation process is the most important process for fabricating the pore structure in the activated carbon manufacturing process. The carbonization material lacking this process has almost no adsorption performance. The carbonized material has no activated pore-forming process, so the surface is brighter and smoother than the activated carbon, and the color is whitish with a slight metallic luster. It feels harder than the activated carbon, and the weight is heavier. The activated coconut shell charcoal is only a kilogram. Around 2.5 yuan, this is the motivation for the sale of low-adsorption activated carbon in the market posing as a high-adsorption activated carbon. It is recommended to choose the actual activated carbon produced by the regular manufacturers and not to choose the inferior products of the trading company.
