1. AC is activated carbon, what is CB
CB filter element is also an activated carbon filter element, which absorbs odors, residual chlorine, some organic matter, etc.
The main filter element of the water purifier generally has \”MF, UF, RO\”, which is suitable for different types of water purifiers and determines the final filtering effect.
MF refers to microfiltration membrane, with a precision of 0.5-1 micron, which can filter large particles of impurities such as sediment.
UF refers to ultrafiltration membrane, with a precision of about 0.01 micron, which can filter large particles of impurities such as sediment, organic matter, bacteria and viruses, etc.
RO refers to RO reverse osmosis membrane, with an accuracy of about 0.0001 micron. It can filter out all impurities in the water, including large particle impurities, bacteria and viruses, scale components, heavy metals, etc. .
2. What kind of garbage is activated carbon
1. Activated carbon is Dry garbage. Dry garbage refers to other garbage, which refers to other domestic waste except recyclables, hazardous garbage, and wet garbage. Wet garbage is also called kitchen waste, that is, perishable waste, which refers to perishable biomass domestic waste such as food waste, leftovers, expired food, melon peels and cores, flowers and green plants, and traditional Chinese medicine residues.
2. Dry garbageThe garbage includes bricks, ceramics, dirt, toilet paper, paper towels and other difficult-to-recycle waste, as well as fruit shells, dust, and food bags (boxes). Sanitary landfilling can effectively reduce pollution to groundwater, surface water, soil and air.
3. What are the definition and properties of activated carbon
1. Activated carbon is also called activated carbon black. It is black powdery or granular amorphous carbon.
2. Activated carbon has a strong \”physical adsorption\” and \”chemical adsorption\” effect, which can adsorb certain organic compounds to achieve removal effects.
3. Activated carbon is mainly used in daily life to absorb formaldehyde, benzene series, ammonia and radon in the indoor air of new homes and continuously released into the air. Toxic and harmful gases.
4. The role of activated carbon in the medicinal industry: The biggest feature of medicinal activated carbon is its fast decolorization speed, strong adsorption capacity, and effective adsorption.
4. What does activated carbon mean
Activated carbon is a Specially treated charcoal is made by heating organic raw materials (nut shells, coal, wood, etc.) in isolation from the air to reduce non-carbon components (this process is called carbonization), and then reacts with gas, and the surface is eroded, creating micropores Developed structure
5. Is activated carbon just wood burned into charcoal?
1. Activated carbon is strictly distinguished according to raw materials and can only be divided into two types:
2. One is wooden activated carbon. Wooden activated carbon includes fruit shell activated carbon such as date shell, peach shell, apricot shell and coconut shell. Among them, coconut shell is the most widely used and relatively expensive fruit shell activated carbon.
3. The second is coal-based activated carbon. Coal-based activated carbon is mainly made from anthracite or lignite. The main thing is low cost. And it can be processed into specific shapes such as spherical and cylindrical shapes.
4. The above raw materials are refined and processed into activated carbon after drying, carbonization and high-temperature water vapor activation.
6. The function of activated carbonWhat are they used for?
1. Activated carbon can purify the air. Therefore, many families have begun to use activated carbon to improve the air quality in their homes.
2. Activated carbon can be used to place newly purchased furniture in cupboards, drawers, refrigerators, or inside shoes to remove odors.
3. Use activated carbon indoors to effectively absorb formaldehyde, xylene and other harmful substances contained in the air (especially in newly renovated houses).
4. Activated carbon can remove residual chlorine, colloids, organic matter, heavy metals (cadmium, chromium, lead, mercury, silver, nickel, etc.), radioactive substances, etc. in water. It is the earliest and most widely used water purification material in water purifiers.
The article ends here. If the questions shared this time about what activated carbon is and what the definition and properties of activated carbon are have solved your problem, then we sincerely feel happy!
