How to muffle the drain pipe, how to muffle the indoor drain pipe

1. Wrap the insulation pipe:

Before the renovation, the drainage pipe is covered with insulation pipes (there are various specifications on the market, thick foam pipes), and then the hanging shed and decorative pipes.

2. Install the keel support:

When renovating, install the keel bracket outside the sewer pipe, and then nail the sound-absorbing panel on the outside.

When renovating the bathroom or kitchen, be sure to insulate the pipes to reduce the noise generated by the water upstairs. During construction, the entire sewer pipe of the sanitation or kitchen should be closed, and only local treatment should be done; Secondly, the sanitary riser should be multi-layer packaging of the pipeline with soundproof materials such as soundproof panels or soundproof cotton;

Finally, the riser is surrounded by light steel keel or light bricks, so that the pipeline can achieve a good effect of reducing noise and moisture. Note: Try not to use wooden keels to prevent the wooden keels from expanding due to moisture and cracking.

The noise of the drainage pipe refers to the impact of the pipe wall when the instantaneous flow of drainage is large, causing vibration and causing noise.

The general solution is to outsource the soundproofing cotton. In fact, it mainly depends on the pipes selected, such as cast iron pipes, which have low self-weight and low noise.

The riser adopts a spiral pipe, which can change the water flow state and can also have a good noise reduction effect.

Generally, the noise of cast iron pipe and soundproof cotton is very small. The plastic pipe is a hard injury, and the noise of the horizontal pipe cannot be solved.

If there is no decoration, you can lay bricks outside the drainage pipe, and after the bricking, it will be better to fill it with centrifugal glass wool, and the glass wool will not get on the body.

At present, almost every household has to do silencing of indoor drainage pipes, and the most common method is to cover the drainage pipes with insulation pipes (there are various specifications on the market, thick foam pipes) before decoration, and then hang the shed and decorate the pipes.

Buy muffler tubes. Or make it hollow. If you can wrap it, make it with soundproof cotton.

Bathroom sewer pipe sound insulation treatment method:

The sewer pipe is generally made of rock wool for sound insulation treatment (must be closed, it is said that rock wool can cause cancer), but generally even if a simple sound insulation is done, the noise will still be heard, just reduced, if there are higher requirements for sound insulation, you can also use wooden boards to make a box, wrap the sewer pipe and then fill it with foaming and other sound-absorbing materials, in addition, with the help of the choice of ceiling materials to reduce noise. Such as: sound-absorbing board, PVC foam board, etc.

Toilet sewer pipes are soundproofed for construction.

Sanitary soundproofing is a very important and easily overlooked part of home decoration. Because of the process of sound insulation treatment, unlike waterproofing and fire prevention projects, it is an indispensable decoration project. Neglecting to insulate the home only affects the quality of life of the owner.

For example, when the wastewater from the upstairs bathroom is flushed and discharged from the sewer pipe, it generally makes a loud noise, especially in the dead of night.

Therefore, we suggest that when the owner is decorating, it is still necessary to consider the drainage pipe of the bathroom and carry out sound insulation construction.

Methods of sound insulation.

1. Prepare materials for sound insulation construction.

Sound insulation material: high-quality sound insulation cotton. It is not recommended to use rock wool or other mineral wools for home renovation because there is a little bit of contamination. Although the ordinary sponge is not polluted, the sound insulation effect is average.

Fixing material: cable tie, easy construction, good effect, firm rope can also be. It is not recommended to use adhesive tape, which is easy to fall off from the soundproof cotton after a long time.

2. Construction of the main sewer pipeline.

Measure the size of the sewer pipe and cut the soundproof cotton into sections.

Wrap a section of soundproof cotton onto the main sewer pipe (i.e., the thick sewer pipe vertically). Note that the soundproof cotton and the sewer pipe should be fixed with cable ties, and the soundproof cotton should not be allowed to move up and down.

Considering that there are other soundproofing processes for the main sewer pipe in the later stage, we recommend that it only be bandaged once.

3. Bandage the ceiling sewer pipes.

In the same way, the sewer pipes on the ceiling are bandaged and soundproofed. Pay attention to the bandaging of each pipe and tie the soundproof cotton tightly.

For the vast majority of families, bathroom ceilings are often used in aluminum gusset ceilings, or PVC ceilings. Neither of these materials is soundproof, so it is recommended to wrap the sewer pipe on the ceiling twice to achieve a better sound insulation effect.

The construction of the ceiling sewer pipe must be made before the ceiling is keeled to facilitate the construction.

4. Carry out brick wrapping and batch cement treatment on the main sewer pipe.

The main sewer pipe was sealed with 95 red bricks, and cement was processed around the red bricks. This is done for two purposes:

The first is to strengthen the sound insulation effect;

The second is to facilitate the later bricklayer to paste tiles.

5. The waterproof treatment can not be forgotten.

After approving the cement putty, don't forget to do waterproofing on the surface of the cement layer. It is obvious that over time, the moisture in the bathroom will gradually erode the soundproof cotton inside. After waterproofing, it can ensure that the soundproof cotton will not deteriorate or deteriorate, and the service life will be longer.

Hello dear! We'll be happy to answer for you. What are the specific specification requirements for sewer pipe silencing?

Hello, 1. During construction, the entire sewer pipe of the bathroom should be closed, and only local treatment should be done; 2. Secondly, the toilet slag riser should be surrounded by soundproof panels or soundproof cotton and other soundproof materials to package the pipeline in multiple layers; 3. Finally, the riser is surrounded by light steel keel or light brick, so that the pipeline can achieve a good effect of reducing noise and moisture. 4. Try not to use wooden keels to prevent the wooden keel from expanding due to moisture and cracking 5. When purchasing sound insulation materials, you must choose products with reliable quality. Because traditional sound insulation materials often contain some harmful substances to the body, therefore, the selection of good quality sound insulation materials can reduce the harm of harmful substances to the human body.

6. The sewer pipe is generally made of rock wool for sound insulation treatment (it must be closed, it is said that rock wool can cause cancer), but generally even if the sound insulation of the simple pants list is made, the noise will still be heard, just reduced, if there are higher requirements for sound insulation, you can also use wood with a wide board to make a box, wrap the sewer pipe and then fill it with foaming and other sound-absorbing materials, in addition, with the help of the choice of ceiling materials to reduce noise. Such as: sound-absorbing board, PVC foam board, etc.

The way to silence the exhaust duct is as follows:

1. Air duct silencing.

The air inlet and outlet of the air duct emit airflow noise, and it is better to use a muffler to eliminate the noise. At some tuyeres, because the air passes through the air duct at high speed, the wind whistle phenomenon will even occur, which requires the installation of mufflers according to the situation. If the installation spacing is insufficient, you can consider replacing the eliminator with a static pressure box and bending, which can also achieve the purpose of noise reduction.

2. Air duct sound insulation.

The high-speed flow of air through the air duct will cause vibration and noise of the air duct, and even surge, and irregular vibration will occur. The air duct is isolated from vibration by wrapping the air duct with sound insulation materials to reduce the noise in the pipe to the outside.

3. Vibration reduction of air duct.

Duct vibrations can propagate to other rooms through contact objects, most commonly where the duct comes into contact with the wall, and without vibration damping, the vibration affects all surrounding rooms. The vibration reduction method here is to fill the air duct through the wall with sound insulation and shock absorption treatment to prevent vibration from passing through the wall. In addition, the air duct support is also a propagation route, replacing the rigid support with an elastic support, which can also reduce the vibration of the air duct.

4. Soundproof ceiling.

Through the installation of soundproof ceiling, the entire ceiling space is used as a return air box, and the air duct is closed to the inside of the ceiling, so as to achieve the purpose of convenient installation and lower noise.

5. Silencing elbow.

The bend of the air duct is a place where noise is often emitted because the air flow is blocked by the flow of air. The noise control method here is to use a muffler elbow, or even replace the entire section of the air duct with a muffler air duct to reduce the airflow noise in the pipe. Whether it is a muffling air duct or a muffling elbow, it has a good muffling effect, and it is highly recommended to use it at the bend of the air duct and the three joints.
