(2) Static density or bulk density: the weight of activated carbon in unit volume of dietary pore volume and interparticle pore volume.
(3) Volume density and particle density: the weight of unit volume of activated carbon that eats pore volume but does not eat interstitial volume between particles.
(4) Strength: namely, the crushing resistance of activated carbon.
(5) Wear resistance: that is, wear resistance or abrasion resistance.
These mechanical properties directly affect the application of activated carbon, such as: density affects the size of the container; The thickness of toner affects filtration; The particle size distribution of granular carbon affects the fluid resistance and pressure drop; Fragmentation affects the service life of activated carbon and the regeneration of waste carbon.
2, the security risk is big:
Need fire protection
Inhalation: leave the scene quickly and go to a place with fresh air. Keep the respiratory tract unobstructed. If you have difficulty breathing, give oxygen. If breathing stops, give artificial respiration immediately. See a doctor.
Ingestion: rinse your mouth with water. See a doctor.
Skin contact: Take off contaminated clothes immediately and rinse with plenty of running water for at least 15 minutes. See a doctor.
Eye contact: lift the eyelid immediately, rinse it thoroughly with plenty of running water or normal saline for at least 15 minutes, and seek medical attention.
Nano-adsorption
The blue holes have a diameter of 0.27-0.98 nm and are arranged in a crystal shape. At the same time, there is weak electricity. The molecular diameters of formaldehyde, ammonia, benzene, toluene and xylene are all between 0.4 and 0.62 nm, and they are all polar molecules, which have the characteristics of preferentially adsorbing harmful gases such as formaldehyde, benzene and TVOC, thus achieving the effect of purifying indoor air. 1, environmental pollution
Air fresheners actually cover up the odor, but they can't eliminate it fundamentally. Therefore, when they are released into the air, they are pollutants, which will produce harmful substances after their own decomposition. Moreover, some air fresheners also contain some impurities, which are also substances that pollute the environment.
2, produce allergies
The ingredients contained in the air freshener are all organic substances, most of which will cause allergies and have some strong stimulation to the respiratory tract, especially for some people with allergies or allergies.
3, leading to serious diseases
Aromatic substances contained in air fresheners can stimulate people's nervous system and affect children's growth and development. The European Consumers Association found through investigation that air fresheners can even induce diseases such as cancer.
4. Possible explosion
Propellants used in aerosol can be divided into incombustibility and flammability. The former is fluorocarbon (such as freon) and the latter is lower saturated hydrocarbon (propane, butane, etc.). ) and ethers (dimethyl ether). In addition, there are products that use compressed gas to increase the pressure in aerosol cans. There are also products abroad that use nitrogen, carbon dioxide and low oxidizing nitrogen to replace propellants. Because many aerosols and spray stock solutions contain flammable substances, they may explode during production, transportation and use. According to the different ignition points, aerosols and sprays can be divided into five grades: incombustibility, flame retardancy, mild flammability, weak flammability and strong flammability. Some countries clearly stipulate that when selling such aerosols and sprays, their risk levels must be marked. Grafted polymer polymerization products, which produce odor and pollution, are adsorbed on their own carriers and undergo chemical reactions. By changing the molecular structure of the target substance, the problem substance is decomposed, so as to achieve the purpose of strong and rapid deodorization and purification. The adsorbed and decomposed substances will not be released again after treatment. Through the grafting coincidence technology of molecular structure, the grafted product and the grafted product form a stable polymer, which fundamentally solves the problem of insufficient stability caused by low molecular structure and will not cause the product performance to decline with time. This feature is the patented technology of Intimate Hall products. The adsorption and decomposition speed is fast and the capacity is large. Low requirements for the use environment.
