Embodiment 1

[0033] A. Inner mold pretreatment: first coat a layer of release agent on the outer wall of the inner lining mold, and then coat a layer of resin on the surface of the release agent, make a surface felt on the resin layer, after the surface felt is cured, Brush high-strength polymer structural glue, spray 2mm-5mm quartz sand particles, half of which is embedded in the structural glue, and half of which is exposed outside, as the inner lining. If there is a requirement for water quality safety, a food-grade inner lining can be selected. Through this setting, it meets the hygienic requirements of the water supply pipeline. In addition, the coating of the inner lining can form a smooth inner wall surface on the inner wall of the pipeline. During the water supply process, it can reduce the wear of the pipeline by water supply resistance and sand and gravel in the water. At the same time, the setting of the lining layer can improve the compactness of the pipeline, avoid corrosion an...

[0049] A. Inner mold pretreatment: first coat a layer of release agent on the outer wall of the inner lining mold, and then coat a layer of resin on the surface of the release agent, make a surface felt on the resin layer, after the surface felt is cured, Brush the polymer high-strength structural adhesive, spray 3mm-4mm quartz sand particles, half of which are embedded in the structural adhesive, and half of which are exposed outside;

[0050] B. Pretreatment of the outer mold: first coat a layer of release agent on the inner wall of the outer mold, and then coat a layer of pure resin gel coat layer on the surface of the release agent, and spray adhesive particles after curing; the gel coat layer Or the function of the surface felt layer is to provide external protection and anti-ultraviolet and anti-corrosion effects. At the same time, after the gel coat layer is applied, the formed pipe is beautiful and smooth, and the outer wall is not easy to wear;

Abstract

The invention discloses a molding process of a polymer concrete pipeline, and belongs to the technical field of pipeline manufacturing. The polymer concrete pipeline comprises an inner lining mould and an outer mould. The molding process comprises the following steps: A, firstly, spraying a layer of mould discharging agent on an outer wall of the inner lining mould, then spraying a fabric resin gel coat layer on a surface of the mould discharging agent, and spraying and scattering quartz sand particles; B, firstly, spraying the layer of mould discharging agent on an inner wall of the outer mould, then spraying a pure resin gel coat layer or the fabric resin gel coat layer on the surface of the mould discharging agent, and curing and spraying and scattering adhesive particles; C, sequentially mounting the inner lining mould, a steel mesh skeleton, a reinforced net and an outer mould in a sleeving manner from inside to outside to form a casting structure; D, casting polymer concrete into the casting structure, and removing the inner lining mould and the outer mould after solidification and molding so as to obtain the polymer concrete pipeline. The molding process of the polymer concrete pipeline disclosed by the invention is simple in process, and the prepared polymer concrete pipeline has excellent performance of all aspects, and has the advantages of high sealing property, high strength, high impermeability, corrosion resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of pipeline production and relates to the design of polymer concrete pipelines, in particular to a molding process of polymer concrete pipelines. The molding process of the invention is simple, and the prepared polymer concrete pipe has excellent performance in all aspects, and has the advantages of high sealing performance, high strength, high impermeability, freeze-thaw resistance, corrosion resistance and the like. Background technique [0002] At present, the pipes used in urban water supply and drainage systems are mainly concrete pipes, which have the advantages of low cost and simple production, but also have disadvantages such as poor resistance to osmotic pressure, poor corrosion resistance, low strength of the pipe body, and large friction coefficient of the inner wall of the pipe. Lifespan is greatly affected. [0003] The production method of existing polymer concrete pipelines is generally to b...
