What matters need attention for hydropower reform?

Hydropower renovation is the most important thing. Therefore, it must be watched carefully during the renovation. Therefore, if the decoration is not good, it is very easy to have a great impact on the future of household life. However, many people are reconstructing the water reform in the hidden project. Fog, do not know what to pay attention to when the decoration, today Xiaobian give everyone talk about!

First, 3 points need to pay attention to the drainage concealment project

1, whether the water pipe leaks

PP-R pipe installation layout should be reasonable, horizontal and vertical, and pay attention to the pipeline shall not be close to the power supply, and the distance between the shortest distance from the power supply is 0.2 cm, the connection between the pipeline and the sanitary appliance must be close, and no leakage can be found through the water test.

2, whether the surface drainage is smooth

Toilets and kitchens are the main places for drainage, so the ground leveling should have a certain slope (2%) to ensure that water collects on the ground into natural water flow and eventually flows to the floor drain. However, it should be noted that the gradient cannot be overemphasized for the sake of smooth water flow, because the slope is over-sloped, which can affect the aesthetics and non-slippage.

3, waterproof layer is waterproof

Kitchen and back walls are higher than other rooms in terms of waterproof requirements. Waterproof paint should be brushed to 1.8 meters high, and other rooms should be 0.3 meters high.

Second, 2 points need to pay attention to wire and cable engineering

1, PVC pipe connection is tight

Power lines must wear PVC pipes when they are embedded in walls, ceilings, floors, or floors. There should be no kinks in the pipes. The bent position of the wire protection tube should use the matching elbow tool or matching elbow, and there should be no folds.

2, PVC pipe protection

After the ground circuit is laid, wood shall be placed on both sides of the laid PVC pipe, or slope shall be made with cement mortar to prevent the PVC pipe from being walked over due to walking back and forth during the construction of the worker. The distance between strong and weak electricity should be about 50 centimeters to reduce the electromagnetic interference between them and prevent accidents.
Third, whether the ground leveling is mainly depends on whether the cement leveling layer on the ground is qualified: First, the place where the rough surface of the original house is uneven should be paved with cement mortar. In addition, the kitchen and toilet should have a slope, and the slope is also very particular.

Fourth, partition base

The problem of the grassroots division of the partition wall is whether or not the column is covered with red brick walls, cement pull plates, etc. Usually, the construction process requires that the pillars of the kitchen and bathroom rooms must use red brick walls, and reserve the observation port, the size must be consistent with the actual, easy to repair in the future; second is whether to do cement coating processing: increase the contact surface of the tiles, and enhance Friction makes the tile more secure.

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.
