For most of my friends, the decoration is a headache. Just in the case of the three-storey house, we now express some of the precautions encountered during the renovation process in a straightforward way.

The first point in the choice of paint also saw a lot of well-known brands on the TV, from the Internet also saw a lot of choices about the choice of paint, but after all, it is not the eye of the fire, but also can not find anything, but had to run on the body less impact.

It is not particularly rare to shake, use a small stick to stir up a little latex paint, and it is better to hang the wire long and continuously fall down. . After the coating is stored for a period of time, there will be delamination, the coating particles will sink, and a layer of water solution will be formed in the upper layer of 1/4 or more. When selecting, we can see that the layer is colorless or slightly yellow, clear and clean. There is no floating matter or very little, which means the paint quality is very good. If the aqueous solution of the glue is turbid, it shows a lot of paint color or internal floating matter, even if it is covered with the surface of the solution, indicating that the quality of the coating is not good or the storage shelf life has passed, it is not suitable for use.

The taste is small, and it smells like there is no strong irritating smell. A strong stimulating latex paint may have a relatively high toxicity. A true environmentally friendly coating should be water-based, non-toxic and tasteless; in addition, it is best not to buy a fragrance-added coating because the additive itself is a chemical product that is difficult to protect. .

After many people have renovated, they will stay in the room for a while, without any test. As a result, after a period of time, various physical discomforts such as dizziness, headache, throat discomfort, memory loss and other symptoms may occur. It is limited to the paint used in the decoration, furniture, flooring, wallpaper, carpets, adhesives, etc. may be the source of this cause.

Another point is the decoration of the bathroom. Waterproofing is a big problem. Individuals in other places are still more assured. However, in terms of waterproofing, we must pay attention to: 1. First of all, do not damage the original waterproof layer, as long as the quality of the house is qualified, the kitchen, The key areas of the bathroom will be waterproof. In the process of decoration, the supervision of the construction of the workers must be done well, and the construction personnel should be reminded not to damage the original waterproof layer. When the water and electricity is changed, it must be destroyed when the original waterproof layer is damaged. It is necessary to repair or redo waterproof in time; 2. The waterproof material selected for quality is the necessary guarantee for waterproofing the bathroom. The waterproof material recommended by the Ministry of Construction is a one-component environmentally friendly polyurethane coating, suitable for small spaces with many pipes and gaps in the bathroom. And the price is not expensive, about 50-60 yuan / square meter, most owners can afford; 3, rainy days do not do waterproof coating construction, the effect will be bad, and in order to have a good waterproof effect, waterproof coating is recommended at least Brushing 3 times; 4, the ground waterproofing should be done before laying the tiles, after laying the tiles to ensure the slope of the ground, the slope is facing the ground

There is also a waterproof test for waterproofing the bathroom. The test is the only standard for testing the truth!

Regarding the decoration of the living room, depending on the design of different units, it is still a matter of personal preference. The color of the living room is adjusted to the depth of the living room. The main wall (background wall) is heavily toned, and the other walls are mainly light yellow, light green or white. .

The last key is the choice of furniture, try to choose environmentally friendly materials, sometimes spend a little more money, buy big brand furniture, it is necessary, not to advertise for big brands, but small series personal experience, Xiaobian home decoration In order to make the map cheap, I bought the TV cabinet and coffee table of unknown manufacturers. Only these two pieces are unknown small brands, which caused the pungent taste in the house for a long time, dizziness and headache, it is really regrettable!

When I was personally renovating, I paid more attention to the above aspects. There may be more important issues that need attention. I don’t list them in this article. I welcome you to discuss with me the things we need to pay attention to during the renovation process. .

Vibration Sensor

The vibration sensor(Vibration Transmitter) is one of the key components in the testing technology of Vibration Measurement. Its main function is to receive the mechanical quantity and convert it into a proportional electric quantity. Because it is also an electromechanical conversion device. So we sometimes call it a transducer, a vibration pickup, etc.

Commonly used vibration sensors are as follows:

1. Piezoelectric resonant

The piezoelectric sheet is used to receive the vibration signal, and the resonance frequency of the piezoelectric sheet is relatively high. In order to reduce the resonance frequency, it is realized by increasing the mass of the piezoelectric sheet vibrating body, and using a spring ball instead of an appendage to reduce the two resonance frequencies and enhance the vibration effect. Its advantages are high sensitivity and simple structure. However, the signal needs to be amplified and sent to a TTL circuit or a single-chip microcomputer circuit, but it is enough to use a triode single-stage amplification

2. mechanical vibration

In the traditional vibration detection method, after being vibrated, the spring ball vibrates at a reduced amplitude for a long time, and this vibration is easy to be detected by the detection circuit. The vibration output switch signal is determined by the output impedance and the resistance value of the matching output. According to the input impedance of the detection circuit, it can be made into a high-impedance output mode.

3. Micro Vibration Sensor

The mechanical vibration sensor is miniaturized, the vibration body is carbonized and sealed, and its working performance is more reliable. The output switching signal is directly connected with the TTL circuit and or the input circuit of the single-chip microcomputer, and the circuit structure is simple. The output impedance is high, and the quiescent working current is small.

Advantages of Vibration Sensors

1. Small size and light weight. It can be applied to some vibration test systems that are greatly affected by the additional mass.

2. It has a wider response frequency range of 4Hz-2000Hz than the magnetoelectric speed sensor, and the mechanical moving parts are not easy to damage
