Ways to reduce the noise of PVC drainage pipes

While adding stabilizers to improve the chemical stability and strength of pvc pipes, the sound insulation performance of the plastic itself has been greatly weakened. Therefore, in the current situation of reliable mechanical performance of pvc drainage pipes, how to solve the problem of sound insulation and noise reduction has become a top priority. The author believes that we can start with the noise source and adopt the following improvement measures to improve its sound insulation performance: ①It is made into double-wall hollow sound-proof PVC drainage pipe The special equipment for PVC pipe extrusion is modified, an intermediate mold is added between the inner and outer jacket, and the outer mold is modified to increase the intermediate distance to form a hollow cavity between the two walls, so that the plasticity of PVC will not be changed. But it can increase the damping of the pipe along the flow direction, thereby increasing Strong sound insulation effect. Using single-wall double-material PVC pipe On the basis of the original single-wall PVC pipe, a secondary formula is carried out, that is, the porous sound-absorbing material formed by plastic foaming technology is used to increase the wall thickness to achieve the purpose of increasing the damping along the outer wall direction, so as to obtain a good sound insulation effect. A set of equipment needs to be added, thus increasing the manufacturing cost. Muffled PVC drainage pipe The PVC pipe is made into a muffled drainage pipe with spiral fins attached to the inner wall. At this time, its outer wall is still a PVC hard plastic pipe (to ensure the required strength of the drainage pipe), but a certain width of flexible and strong soft is attached to the inner wall Plastic spiral belt, which unloads part of the impact pressure of the water flow onto the spiral belt, thereby buffering the pipe wall.

What is the difference between PVC water supply pipe and PVC drainage pipe

1. Different purposes: one for water supply and one for drainage. PVC water supply pipes are mainly used for: a. Indoor water supply and reclaimed water systems for civil and industrial buildings; b. Buried water supply systems for residential quarters and factories; c. Urban water supply pipeline systems; d. Water treatment plant water treatment pipeline systems; e. Marine aquaculture; f. Garden irrigation, well sinking and other industrial pipes. PVC drainage pipes are mainly used for building drainage and domestic sewage drainage. 2. Different specifications: PVC water supply pipes have more specifications and models, and PVC drainage pipes have relatively fewer specifications and models, because the drainage system itself does not require too many specifications. Even with the same model (outer diameter), the wall thickness of the water supply pipe and the drain pipe are often different, because the water supply pipe requires pressure, and the drain pipe usually does not need to consider the pressure. 3. The price is different: This will not be explained in detail, and the specific price can be consulted by each manufacturer.
