Abstract

The invention belongs to the technical field of plastic pipeline, and discloses a low roughness PE-RT pipeline preparation method. The low roughness PE-RT pipeline preparation method comprises following steps: A, an antiscale material is prepared, wherein a coupling agent is adopted to process nanometer inorganic particles, centrifugation, drying, and grinding are carried out, a base material, polytetrafluoroethylene micro-powder, and a processing auxiliary agent are added, stirring mixing is carried out using a material mixing device so as to obtain a uniformly mixed pre-mixed material; and B, the PE-RT pipeline is prepared, wherein a double-layer co-extrusion single screw extruder is adopted, external layer pressure bearing layer extrusion of the PE-RT raw material, and internal layer antiscale layer extrusion of the pre-mixed material are carried out so as to obtain the PE-RT pipeline with a double layer structure. According to the preparation method, the internal part of the PE-RTpipeline is provided with an antiscale layer, so that the surface energy and roughness of the internal surface of the PE-RT pipeline are reduced, adherence of dirt impurities is reduced, and pipelineblocking is prevented.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a low-roughness PE-RT pipe preparation technology. Background technique [0002] In recent years, PE-RT pipes have been widely used in the field of floor heating. However, after several heating seasons, PE-RT pipes will have fouling on the inner wall of the pipes, which will affect the heat exchange efficiency of the system and require periodic cleaning. The main reasons for scaling on the inner wall of PE-RT pipes are: (1) floor heating water is recycled water, and it is easy to form sewage after long-term circulation in heaters, pipes and radiators; (2) the surface energy of pipe materials is large, It is easy to stick to the oil stains in the circulating water, and the oil stains further stick to the fine impurities, and finally form a dirt layer on the pipe wall; (3) The inner surface of the pipe is rougher, which further accelerates the deposition rate of dirt. The ab...
