During the renovation, we are paying more attention to the decoration quotation, that is, we are afraid of being deceived. In fact, what we should do is to carefully review the decoration drawings to ensure the accuracy of the design drawings, so that we can avoid being decorated by the decoration company!
First, see the proportion of drawings
Often encountered in the effect of the figure on the beautiful shape, the actual effect is very different. The reason for this is that the designer did not design according to the construction drawings, but made the drawings according to the beautiful pictures. Therefore, a design drawing must be made in strict proportions.
Second, see if the detailed size is specified
Some design drawings due to the designer did not make careful and detailed measurements at the site where the construction is to be prepared, eventually resulting in the omission of many dimensions in the design, especially some key dimensions, which may result in the disconnection of the design from the construction.
Third, see if the choice of materials is clear
Many owners will pay attention to the decoration company's quotations, worry about being deceived, a careful inspection of the item, but in fact the design drawings should also be marked on the name of the main material and the brand of the material, which is very beneficial for future construction workers in accordance with the drawings construction .
Fourth, see if the production process is marked
The necessary production processes are marked on the construction drawings. On the one hand, it is to facilitate the construction, and on the other hand, it can also prevent workers from cutting corners during the construction process and ensuring that they get an expected project.

Design knowledge
Sintered Ferrite Magnet, hard ferrite, hard ferrite magnet is also called Ceramic Magnets.
Sintered ferrite magnets are available in isotropic magnet and anisotropic magnets. The magnetic properties of isotropic ferrite are low. Since they have nearly the same magnetic properties in all directions, so isotropic ferrite magnets can be magnetized in many different directions or in multi-poles. Anisotropic ferrite magnets have better magnetic properties compare with isotropic ferrite magnets. However this type of magnets can only be magnetized along a preferred direction.
Permanent ferrite magnets are made of hard ferrites, which have a high coercivity and high remanence after magnetization. Iron oxide and barium or strontium carbonate are used in manufacturing of hard ferrite magnets. The high coercivity means the materials are very resistant to becoming demagnetized, an essential characteristic for a permanent magnet. They also have high magnetic permeability. These so-called ceramic magnets are cheap, and are widely used in household products such as refrigerator magnets. The maximum magnetic field B is about 0.35 tesla and the magnetic field strength H is about 30 to 160 kiloampere turns per meter (400 to 2000 oersteds). The density of ferrite magnets is about 5 g/cm3.
The most common hard ferrites are:
Strontium ferrite, SrFe12O19 (SrO·6Fe2O3), used in small electric motors, micro-wave devices, recording media, magneto-optic media, telecommunication and electronic industry.
Barium ferrite, BaFe12O19 (BaO·6Fe2O3), a common material for permanent magnet applications. Barium ferrites are robust ceramics that are generally stable to moisture and corrosion-resistant. They are used in e.g. loudspeaker magnets and as a medium for magnetic recording, e.g. on magnetic stripe cards.
Why choose Ferrite Magnet?
1. Low cost and low price.
The raw material cost is very cheap and manufacturing process is simple. So the price if it is very low.
2. Nice temperature stability
Ferrite magnets can be used in the working temperature from -40℃ to 200℃.
3. Well prevent corrosion
The raw material of sintered ferrite magnet is oxide, so ferrite magnets will not be rusted under severe environment nor affected by many chemicals.
