Why do fan blades get dirty so easily?

Is the landlord asking about the computer fan?

First of all: the environment in which it is used determines the service life of the fan. If the computer is placed in an environment with a lot of dust, it objectively increases the probability of dust absorption.

Secondly: in principle, most of the computer fans on the market are produced by the process of suspended shaft, in the process of high-speed rotation of the fan, the friction between the suspended shaft and the surrounding air produces a large amount of static electricity, and the static electricity is distributed on the edge of the fan as a whole, adsorbing dust (so the dust accumulation on the edge of the fan blades is more serious than that near the shaft).

If you want to solve the problem of fan adsorption back to the city, you must consider the above two aspects separately.

The first is to improve the use environment as much as possible to reduce dust (the computers of high-tech units are placed in the clean room), and the second is to apply a little glycerin (pure glycerin) to the shaft gap of the fan to reduce the generation of static electricity.

Because the blades of the fan rotate rapidly, the blades have a much greater chance of coming into contact with dust particles in the air. Second, dust particles in the air can adhere to the leaf pieces due to high-speed collisions with the leaf pieces. So, the fan blades will get dirty easily.

The high-speed rotation of the fan blades and the high friction of the air generate static electricity, which adsorbs many fine particles and accumulates more and more.

When the fan blade is in use, the fan blade rotates at high speed and rubs against the air, so that the static electricity on the fan blade has the property of adsorbing light objects due to the cause of friction electricity, so as to adsorb the light objects in the air, that is, dust.

with feet. If you think about it, you know: fan blades are mainly used for.

Absorb the air on the back, through the high-speed transport of the leaf surface to form the wind quickly blow out to form the wind, since it is to absorb the air on the back, even the dust in the air is sucked over, the fan blade does not have long eyes, as long as the air does not need dust, so it is dirty, the front is also dirty, the leaf has to do work to absorb the air, it has to be transported quickly, the air that is sucked over must always be in contact with the air in the process of transport, so the front is also dirty. Got it, if I didn't understand, I only knew so much pulling. It should be a matter of air

The leaves of the electric fan are covered with dust.

The reason is that "when the electric fan is in use, the fan blades rotate at high speed and rub against the air, so that the fan blades carry static electricity due to the friction electricity" has the property of "adsorbing light objects".

Because when the electric fan is in use, the fan blades rotate at high speed and rub against the air, so that the fan blades are electrostatic due to the friction electricity, thereby absorbing light objects (i.e. dust) in the air

Of course, it is necessary to clean the appliance frequently to keep it tidy, and we must also be careful not to let the blade or fan blade scratch ourselves during the cleaning process, so as not to cause injury.

Use baking soda, white vinegar and dish soap, make your own bottle of detergent, then add water to the watering can and spray it directly on the blades of the electric fan, and the dirt will slowly fall off.

Cut off the power supply, use a screwdriver to unscrew the screws on the fan, then take off the protective net, and gently scrub the fan blades with a clean rag.

Most of the methods are to disassemble the fan, remove the fan blades, and then clean them with dish soap.

You can use a damp rag dipped in an appropriate amount of dish soap to wipe it, and then wipe it dry with a dry rag, so that the dirt on the fan blades of the electric fan can be quickly removed.

The more blades the better, but according to the required air volume and air pressure, the more blades and the higher the air volume, the fan noise will increase.

The size of the leaf fan determines the strength and direction of the wind. The function of the electric fan is to convert the electromotive force into wind energy, the size of the wind speed is determined by the speed of the motor, and the fan blades are the source that determines the direction of the wind, so the general household fan is three fan blades, and it is not that the more fan blades, the better.

How it works. When the electric fan is working, the temperature in the room does not decrease, but rises. Let's analyze the reasons for the increase in temperature:

When the electric fan is working, because there is an electric current passing through the coil of the electric fan, the wire is resistive, so it will inevitably generate heat to release heat, and the temperature will naturally rise. There is a lot of sweat on the surface of the human body, and when the electric fan is working, the indoor air will flow, so it can promote the rapid evaporation of sweat, combined with "evaporation needs to absorb a lot of heat", so people will feel cool.

Electric fans are easy to get dirty because when the fan rotates, it rubs against the air to generate static electricity and attracts dust.

Electric fan cleaning steps.

1. Unplug the power supply first, and then prepare a cloth that does not shed lint.

2. Prepare dish soap (other effective detergents are also available).

3. Soak the rag with water and pour an appropriate amount of dish soap.

4. The rag should be wrung out of the water, but not too dry, to ensure that it will not drip.

5. Wipe the whole electric fan normally, focusing on wiping the fan and fan cover. When removing the fan cover, you need to remove the fixed clamp first, and the fixing method of the clip is different depending on the situation.

6. Wipe the fan blades and fan blade cover, except for the first one or two use of dish soap, then wash the rag and wipe it directly until there is no dish soap residue on the surface of the fan. (Remember that the towel should not be too wet to prevent damage to the internal accessories of the fan).

7. After wiping, the fan looks brand new, it needs to be dried for a few minutes and then turned on the electric blower, and the fan will be clean and dry.

The friction between the fan and the air generates static electricity that adsorbs small objects. Rubbing it with alcohol can get better temporarily.

<> "Tips for cleaning fans.

First prepare a container, pour and pour in an appropriate amount of baking soda.

Then pour in an appropriate amount of white vinegar.

Then pour in some dish soap.

Finally, pour in water to dilute.

Stir well and slide into the watering can.

Spray the prepared solution on the fan blades, and remember to spray the reeds before and after!

Finally, put the fan in an open place and turn on the fan, so that the stains on the fan will fall off by themselves, which is very simple and convenient! Let's go back and give it a try!
