Problems solved by technology

However, the noise test shows that the noise reduction effect of these technologies is not obvious, and even the noise reduction effect of the UPVC core foam pipe is not as good as that of the ordinary UPVC drainage pipe

Abstract

The invention discloses a monolayer wall PVC mute drainage pipe, which has a monolayer wall made of materials as: PVC resin for 100 parts, chlorinated polyethylene for 10 to 20 parts, barium sulfate for 150 to 350 parts and other relative processing aids of small amount, wherein the inner wall of the monolayer wall PVC mute drainage pipe (1) is opened with spiral reinforcement (1a), the inner wall of the other monolayer wall PVC mute drainage pipe (1) is opened with a hollow chamber (1b) in axial direction; also the inner wall of the monolayer wall PVC mute drainage pipe can be both opened with spiral reinforcement (1a) and axial hollow chamber (1b). The invention can reduce noise to 30 to 40 dB, which completely meets the requirements of national city environment noise standard GB3096-93 and only needs one pipe wall layer; the pipe wall can both achieves noise reducing requirement and can meet usage mechanic strength; the invention has simple device and small investment, and greatly lowers cost.

Description

technical field [0001] The invention belongs to a drainage pipe, in particular to a polyvinyl chloride silent drainage pipe with a single-layer pipe wall which significantly reduces drainage noise. Background technique [0002] UPVC drainage pipe is widely used all over the world because of its low cost, beautiful appearance, convenient installation and maintenance, and long service life. But it has a fatal weakness. High-rise buildings or even middle-rise buildings make a lot of noise when draining water, which affects the quietness of the living room and sometimes wakes people up from their sweet dreams. In the face of noise, we have made a lot of efforts and successively developed UPVC core foam pipe, solid wall UPVC inner spiral noise reduction pipe, empty wall UPVC inner spiral noise reduction pipe, swirl noise reducer, hydrophilic inner wall swirl Noise reducer, hard polyvinyl chloride swirl noise reduction tee joint, etc. Foreign Japanese scholars have done a lot of...
