There are often reports in the news that some people have suffered from cancer due to home decoration pollution. It can be seen that the pollution after home renovation is relatively serious. However, formaldehyde in new house decoration cannot be avoided. In addition to environmental protection options, we should also understand some measures in addition to formaldehyde. The following Xiaobian will bring everyone the formaldehyde removal method for the floor . Floor removal method of formaldehyde A common method of removing formaldehyde from the floor is to cultivate some green plants in the space. Plants have a certain adsorption effect on formaldehyde. For example, green plants such as green cherries, spider plants and aloes can effectively absorb harmful substances in the air. The effect of Chlorophytum is most obvious. It can absorb more than 80% of harmful gases, but it must be replaced frequently. Floor addition to formaldehyde method II Bamboo charcoal, activated carbon adsorption method is the most commonly used method of removing formaldehyde. The adsorption capacity of bamboo charcoal is 2 to 3 times stronger than ordinary charcoal, and it is a new type of environmentally friendly material. Bamboo charcoal is used for physisorption through tens of thousands of holes on the surface, and the adsorption effect is complete, and it is not easy to cause secondary pollution. Floor addition to formaldehyde method three Guan Chumei's principle is to remove formaldehyde. The principle is to circulate the hydrocarbons and some inorganic substances in the air through the air and make contact with the surface of the photocatalyst, so that they can be adsorbed or oxidized and decomposed into carbon dioxide and water. Floor addition to formaldehyde method four Anion treatment is a more scientific method. It increases the content of negative ions in the room. Negative ions in the air can effectively decompose formaldehyde, toluene and other decoration pollution gases. The products are also carbon dioxide and water. This method is a good choice to solve the decoration pollution and can improve the indoor environment. Xiao Bian's introduction to the formaldehyde removal method on the floor is here. I hope to bring you help. For more information, please pay attention to this site. Formaldehyde removal method except formaldehyde Alnico (AlNiCo) is the first developed a permanent magnet is made of aluminum, nickel, cobalt, iron and other trace metals composition of an alloy.According to different production process is divided into sintered Alnico (Sintered AlNiCo), and cast aluminum nickel and cobalt (Cast AlNiCo).Product shape of the round and square. Sintered products limited to the small size, their production out of rough tolerance is better than the rough cast product can be better workability.

Alnico alloys can be magnetised to produce strong magnetic fields and have a high coercivity (resistance to demagnetization), thus making strong permanent magnets. Of the more commonly available magnets, only rare-earth magnets such as neodymium and samarium-cobalt are stronger. Alnico Magnets produce magnetic field strength at their poles as high as 1500 gausses (0.15 teslas), or about 3000 times the strength of Earth's magnetic field. Some brands of alnico are isotropic and can be efficiently magnetized in any direction. Other types, such as Alnico 5 and alnico 8, are anisotropic, with each having a preferred direction of magnetization, or orientation. Anisotropic alloys generally have greater magnetic capacity in a preferred orientation than isotropic types. Alnico's remanence (Br) may exceed 12,000 G (1.2 T), its coercivity (Hc) can be up to 1000 oersteds (80 kA/m), its energy product ((BH)max) can be up to 5.5 MG·Oe (44 T·A/m). This means that alnico can produce a strong magnetic flux in closed magnetic circuits, but has relatively small resistance against demagnetization. The field strength at the poles of any permanent magnet depends very much on the shape and is usually well below the remanence strength of the material.
Alnico alloys have some of the highest Curie temperatures of any magnetic material, around 800 °C (1,470 °F), although the maximal working temperature is normally limited to around 538 °C (1,000 °F).[4] They are the only magnets that have useful magnetism even when heated red-hot.[5] This property, as well as its brittleness and high melting point, is the result of the strong tendency toward order due to intermetallic bonding between aluminium and other constituents. They are also one of the most stable magnets if they are handled properly. Alnico magnets are electrically conductive, unlike ceramic magnets.
Alnico magnets are widely used in industrial and consumer applications where strong permanent magnets are needed; examples are electric motors, electric guitar pickups, microphones, sensors, loudspeakers, magnetron tubes, and cow magnets. In many applications they are being superseded by rare-earth magnets, whose stronger fields (Br) and larger energy products (BHmax) allow smaller-size magnets to be used for a given application.
