>>>Clear seven errors in decoration pollution
Home decoration, to say that there is no pollution, it is said that nothing more than the pollution is more or less, the problem of exceeding the standard or not exceeding the standard, maybe you buy everything not exceeding the standard, but they put together, it is inevitable that they will not exceed the standard, say It is very low with the standards currently formulated by our country. After all, are we developing countries? The standard is set high. How do you call domestic companies to survive? For example, the standard of tap water for people in the United States and Europe is a direct reference. How can we drink straight when we wash our clothes in the tap water? Therefore, it is impossible for decoration to be pollution-free. It is also said that the source of decoration pollution is decoration materials. As a decoration company and decoration process, there are ways to reduce it but it is impossible to completely eliminate it. Therefore, we must not only take the decoration company to say things because of the decoration, so we have to consider and pay attention to many aspects. Collected and summarized several steps to remove the pollution after renovation for your reference.
The first step is to open the window and ventilate the room. The decoration has just ended. The pollution is sure to be several times, several times, or even hundreds of times higher than the standard. Therefore, in the initial period of one to two weeks, no means is effective. The best method is to open the window for ventilation. As soon as possible during the Spring and Autumn period, the main pollutants in the room will be discharged outdoors. Of course, the indoor and outdoor air circulation will be fast. It will take more than a week, and it will take a long time in summer and winter. In addition, in order to accelerate the exchange of indoor and outdoor air, it can also be used. Fan blowing.
Step 2: After the first step, indoor pollution has been changed from several times or even hundreds of times to a few times or almost no limit. At this time, pollutants are emitted into the slow release process. No matter how you ventilate, It is also impossible to remove it all at once. At this time, we must prepare for a protracted war. We can use the following methods: The first is the category of flower plants, such as spider plants, cactus, green plants, etc. These plants have a certain degree of odor absorption. Can eliminate harmful substances in the air; followed by the purchase of some special deodorants, these deodorants can be rubbed on the furniture, said to have a certain effect, such as chemistry, biology, optics, etc., but the actual results have not been tested in person , It is best to use it after careful inspection, but also pay attention to whether there are toxic and side effects, whether it will cause damage to furniture (it is said that some things will cause the furniture to change color), and whether the use is convenient. Of course, ventilation and ventilation should be continued at this stage.
Step 3: After the second step, you basically need to check in. At this time, the ventilation and vegetal methods still need to be used. At this time, you can use activated carbon to continue smoking. Everyone knows that the active carbon that people wear during the SARS period Masks, decoration workers spray paint when wearing gas masks, household water purifiers or water purifiers, etc. are using activated carbon, industrial activated carbon mainly used injection activated carbon, gold extraction of activated carbon, white wine purification special activated carbon, medicinal activated carbon, blood purification Activated carbon, cigarette filter activated carbon, reagent activated carbon and so on. The biggest benefit of activated carbon is absolute safety, reliability, usefulness, no pollution, no toxic and side effects, green and environmental protection, not emitting odor, and inexpensive, affordable, easy to use.
The principle of activated carbon is that activated carbon is a porous carbonaceous material. Its well-developed pore structure makes it have a large surface area, so it is easy to fully contact with toxic and harmful gases in the air. The strong adsorption force field around activated carbon pores will immediately The toxic gas molecules are sucked into the pores, so the activated carbon has a strong adsorption capacity.
Not all activated carbons have gas adsorption capacity. Only those activated carbons with a large diameter of pores that are slightly larger than the molecular diameters of poisonous and harmful gases have strong adsorption capacity. Therefore, only high-quality husk-like activated carbons are used to better adsorb home-pollution. effect. Generally good husk activated carbon is granular.
The other is that new car pollution is similar to interior decoration pollution, and similar methods can be used.
Finally, because the indoor harmful gas is a slow release process, even if there is no better air purification product, people in the closed room for too long, it is easy to cause some diseases. When consumers choose the above products, especially for newly renovated users, they must always pay attention to window ventilation, and usually pay more attention to physical exercise. This is the basis of our health.

Sintered NdFeB magnets are prepared by the raw materials being melted in a furnace, cast into a mold and cooled to form ingots. The ingots are pulverized and milled; the powder is then sintered into dense blocks. The blocks are then heat-treated, cut to shape, surface treated and magnetized.
As of 2012, 50,000 tons of neodymium magnets are produced officially each year in China, and 80,000 tons in a "company-by-company" build-up done in 2013. China produces more than 95% of rare earth elements, and produces about 76% of the world's total rare-earth magnets.
Neodymium magnets are graded according to their maximum energy product, which relates to the magnetic flux output per unit volume. Higher values indicate stronger magnets and range from N35 up to N52. Letters following the grade indicate maximum operating temperatures (often the Curie temperature), which range from M (up to 100 °C) to EH (200 °C).
Sintered Nd2Fe14B tends to be vulnerable to corrosion, especially along grain boundaries of a sintered magnet. This type of corrosion can cause serious deterioration, including crumbling of a magnet into a powder of small magnetic particles, or spallingof a surface layer.
This vulnerability is addressed in many commercial products by adding a protective coating to prevent exposure to the atmosphere. Nickel plating or two-layered copper-nickel plating are the standard methods, although plating with other metals, or polymer and lacquer protective coatings are also in use.
Neodymium magnets have replaced alnico and ferrite magnets in many of the myriad applications in modern technology where strong permanent magnets are required, because their greater strength allows the use of smaller, lighter magnets for a given application. Some examples are:
ï‚·Head actuators for computer hard disks
ï‚·Magnetic resonance imaging (MRI)
ï‚·Mechanical e-cigarette firing switches
ï‚·Locks for doors
ï‚·Loudspeakers and headphones
ï‚·Magnetic bearings and couplings
ï‚·Electric motors:
ï‚·Cordless tools
ï‚·Servomotors
ï‚·Lifting and compressor motors
ï‚·Synchronous motors
ï‚·Spindle and stepper motors
ï‚·Electrical power steering
ï‚·Drive motors for hybrid and electric vehicles. The electric motors of each Toyota Prius require 1 kilogram (2.2 pounds) of neodymium.
ï‚·Actuators
ï‚·Electric generators for wind turbines (only those with permanent magnet excitation)
ï‚·Direct-drive wind turbines require c. 600 kg of PM material per megawatt
ï‚·Turbines using gears require less PM material per megawatt
