There is a certain standard for the construction and acceptance of the installation and finishing project. Although we cannot implement it in accordance with regulations, it is also of certain reference value. The following Xiaobian I summarized the installation features of Yuba and exhaust fans for everyone to understand. .
Yuba, exhaust fan installation and ceiling installation
Many owners will install bath heaters or exhaust fans after installing the aluminum buckles. Some installation unions directly fix them to the aluminum buckle board. As a result, there will be more problems when they are used in the future:
1. When the exhaust winds, it will make a very loud noise - because it resonates with the aluminum buckle.
2. After a long time, the aluminum buckle plate will be deformed and bent, and the Yuba or exhaust fan will crumbling.
Therefore, if you install a Yuba or exhaust fan, you should first set a good position, according to the product model, in the aluminum plate before the workers to install a frame on the roof, to install the aluminum buckle plate, the bathroom heater or exhaust fan directly fixed to this frame, It is strong and safe.
Radiator features
The steel radiator is rich in design, so it has a beautiful appearance and a smooth surface, integrating practicality and decorativeness.
The corrosion resistance of ordinary steel is rather poor, and it is best to use steel or T12 high-quality low-carbon steel for the production of steel radiators, but many small businesses use inferior steel, which is the reason for the huge price difference between different brands. One, but the consumer is difficult to distinguish with the naked eye, so buy radiators try to choose brand-name products. In addition to the purchase of steel radiator must understand the inner wall of the radiator is not done within the anti-corrosion, a good radiator should have double anti-corrosion, and many radiators even have no anti-corrosion, is extremely unsafe. At present, the internal anti-corrosion technology of steel radiators is relatively mature. As long as it is a serious and responsible company, the quality of internal anti-corrosion is very pass. Therefore, the steel radiator can be used both in the central heating system and in the self-heating system, but it is suitable for the wide water channel product in the central heating system, and the self-heating system is suitable for the product of the small water channel.
Let us talk about the characteristics of aluminum alloys: The heat dissipation of aluminum alloys is very good, and the corrosion resistance of aluminum alloys is very poor.
People who understand the characteristics of aluminum know that the chemical activity of aluminum in the alloy is very lively, and it can easily react with oxygen in the air to form a dense protective film of aluminum oxide. The thickness of the film is about 1μm, which is the same as the substrate. The bond is strong enough to passivate the surface of the coating and prevent the self-oxidation from proceeding. Therefore, aluminum alloy itself is not afraid of oxygen, there is no oxygen corrosion. Let's talk about the internal anti-corrosion principle of the radiator: The internal anti-corrosion treatment of the radiator is to coat the inner surface of the radiator with an organic coating with good adhesion (cohesive force) and corrosion resistance, and to isolate water from steel or aluminum. , And thus play a role in antiseptic. Due to the dense aluminum oxide protective film on the surface of the aluminum alloy, the anti-corrosion coating is difficult to adhere to. Even if it is painted on, the inner surface of the aluminum alloy anti-corrosion coating blocks can easily fall off under the water inside the radiator. Therefore, aluminum alloy radiators must not be used in centralized heating systems, but they are very suitable for use in self-heating systems. Compared to steel radiators, aluminum alloy radiators have very prominent advantages in self-heating systems, so now domestic manufacturers have introduced energy-saving combinations of wall-hung boilers and aluminum alloy radiators, which are specially provided for self-heating families. It should be a very good choice.
