Air purifiers are inseparable from the knowledge of filter maintenance. This is the core. The filter filters the air and leaves harmful substances on the filter, so regular replacement is necessary. Let ’s take a look.
There are more than one filter used in the air purifier, so the maintenance methods are also different. First of all, the pre-filter is used. The dust collected by the pre-filter will be more. The biggest impact will eventually have a certain impact on the air purification effect. Therefore, when maintaining the air purifier filter, the first thing to pay attention to is to clean it. The cleaning method is very simple, as long as it is dust Suck away or flush directly with clean water. In the process of curing, care must be taken to move gently to avoid physical damage to the filter, which will cause it to fail to exert its desired effect during subsequent use.
Secondly, we must pay attention to the cleaning of the filter. The cleaning method of the filter is fundamentally different from the pre-filter. In the process of cleaning it, we must not only focus on removing the dust, but also need to pay attention to regularly put it in the sun. Under the sun, the purpose of this method is to eliminate the bacteria present on the filter. After that, the effect on the purification effect will be more ideal. For example, many users use activated carbon filters. This type of filter will remove air. The bacteria absorbed in the medium remain in the activated carbon. It is difficult to remove these bacteria completely by the general method of removal, so it is necessary to expose them to the sun.
According to different brands of air purifiers, the number of existing filters is also different. For example, some more high-end air purifiers, in addition to the pre-filter and filter described above, there will be Stinky filter. There are few ways to use this type of filter cleaning, mainly clean water. In the cleaning process, low corrosive cleaning fluid can be used. It is necessary to pay attention to the use of high corrosive cleaning. Cleaning fluid, which will affect the filter material. In addition, it must be dried for a certain period of time after cleaning, and it can be put back into the air purifier when it is completely dry, if it is not completely dry. Next, put it in an air purifier, the deodorizing function will be reduced a lot, and because of the presence of water stains for a long time, the damage to the filter itself is still greater.
Although some of the hardware of the air purifier needs to be replaced and cleaned, there are some components that cannot be maintained by themselves, such as ionizers. This type of accessories is usually built into the air purifier, so it will not be affected. All kinds of pollutants are attacked, so there is no need to clean them. If they are cleaned, it is likely to be counterproductive, which will reduce their efficiency in the work process and even cause them to be unable to be used normally. In this regard, it is best not to disassemble this type of accessories to avoid damage, which will affect the use of daily air purifiers.

Heat Treated Steel Bar And Tube
Heat treated steel bar is produced by heating and cooling in different temperature based on the steel grades to improve the steel bar mechanical properties or machinability for various industrial applications. Heat treated steel bar includes annealed steel bars, Normalized Steel Bar, quenched and temper qt steel bar.
Annealed Steel Bar has better ductility and lower hardness, which can be easier to be machined. The annealing processing is usually widely used for steel grade with higher carbon content above 0.5%. However, some low carbon steel also requires to do annealing for special usage such as 20CrMnTi gear steel. For some special material such as 20CrMnTi gear steel and GCr15 such bearing steel, spheroidizing annealing is often required.
Normalized steel bar sometime is also one kind of annealing processing. It mainly changes the grain to remove the impurities in steel and improves the strength and hardness. For some hot rolled steel bars, to keep the basic mechanical properties, normalizing is often used.
Quenching and Tempering, abbreviated as Q&T is a king of processing that strengthen or harden steel bars by heating the materials and then cooling in water, oil or other liquid medium, that rapidly the change from austenite to perlite to get the proper properties for various usage. The quenched & tempered steel bar materials are usually with carbon from 0.30% - 0.60%, it is widely used as merchant bars in components of various machines.
Our advantages on producing heat treated steel bars:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Wide range of Cold Drawn Steel Bar sizes: from 10mm to 150mm
3) Different cold drawing medias powder or oil to get different surface
4) Straightening machines to get better straightness up to 0.5mm/m
5) Grinding and polishing machines to get better roughness upto 0.4um
6) Heat treating furnaces to adjust the mechanical properties
7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
8) Multiple packages to avoid broken packages and anti-rusty
