Description
Technical field
The utility model relates to the technical fields of pipe member molding die, in particular for three type polypropylene pipe inner walls
The die geometry of good antiscale property formable layer is not related to its mechanical connecting structure.
Background technique
PP-R pipe has energy-saving material-saving, environmental protection, light compared with the pipelines such as traditional cast iron pipe, coating steel pipe, pipe of cement
Matter is high-strength, corrosion-resistant, inner wall smooth non-scaling, construction and the advantages that maintenance is easy, long service life, is widely used to build
The problem of plumbing field, but in recent years, water supply secondary pollution, is prominent.The output water for meeting standards for drinking water quality arrives
After client deteriorating water quality even deteriorate be it is unqualified, this is because output water reach have passed through before user several kilometers even on
Hundred kilometers descend water supply network system bulkily, and secondary pollution has occurred.It is counted according to the investigation to domestic 50 cities: pipe network
Water turbidity increases 0.38NTU than output water, coloration increases by 0.45 degree, and iron increases 0.04mg/L, manganese increases 0.02mg/L, bacterium increases
Add 18/mL, the chlorine residue of pipe network end drop to 0.015mg/L, coliform increase the total qualification rate of 0.4/L. water quality averagely decline
To 83.4%, show that water quality has deteriorated.Therefore the secondary pollution of water quality during transportation is a the problem of can not be ignored.
Although PP-R water-feeding pipes itself have the characteristics that inner wall smooth is less scaling, main application is in pipeline of registering one's residence
In, the precipitating and bacterium of the silt present in the water of main pipeline secondary pollution and scale and microorganism is a large amount of numerous
It grows, gradually forms biological clay, when flowing through pipeline for a long time, PP-R pipe inner wall can be deposited in, bring drinking water to user
Security risk.
Summary of the invention
The purpose of this utility model is to provide the die geometry for three type polypropylene pipe inner wall good antiscale property formable layers,
In Inner tubing layers production, extend in tube forming mouth mold and core model position and form straight segment length, and is sprayed simultaneously in extension
High polishing wear-resistant paint is applied, normal pressure when increasing tube forming by this method when surface forming makes tubing reach higher
Compactness, and tube surfaces form brighter and cleaner product surface by the further friction with spraying mouth mold, and existing
PP-R water-feeding pipes inner wall is increased to Ra0.1-0.2 by Ra0.8-1.6 compared to the tube surfaces finish that the technique is produced, and produces
Raw mirrored effect, from physics aspect substantially reduce scale can adhesive ability, reduce the resistance of water flow, long-time service is not easy to accumulate
Scale reduces scale etc. in the adhesive ability of tube wall.Overcome shortcoming and defect existing in the prior art.
To achieve the goals above, the technical solution of the utility model are as follows: be used for three type polypropylene pipe inner wall good antiscale properties
The die geometry of formable layer, including tube forming mouth mold, the centre bit in tube forming mouth mold are equipped with core model, tube forming mouth mold
Annular runner is formed between interior cavity wall and core model outer wall, runner is by the oblique runner by being located at annular runner leading portion and is located at ring
The horizontal run of shape runner back segment is constituted, and the rear end of tube forming mouth mold is equipped with an insert, is formed and above-mentioned annular flow in insert
The continuously distributed extension runner in road, the extension runner are straight annular runner, extend on the interior cavity wall of runner and spray high polishing
Wear-resistant paint, and wear-resistant paint layer is formed, wear-resistant paint layer is made of three layers of teflon coatings.
The utility model discloses the die geometry for three type polypropylene pipe inner wall good antiscale property formable layers, tubing at
Type mouth mold and core model position increase insert to extend the straight segment length of molding, and spray the high wear-resisting painting of polishing in extension simultaneously
Material, normal pressure when increasing tube forming by this method when surface forming, makes tubing reach higher compactness, and manage
Material surface forms brighter and cleaner product surface, in existing PP-R water-feeding pipes by the further friction with spraying mouth mold
Wall is increased to Ra0.1-0.2 by Ra0.8-1.6 compared to the tube surfaces finish that the technique is produced, and generates mirrored effect, from
Physics aspect substantially reduce scale can adhesive ability, reduce the resistance of water flow, long-time service is not easy to accumulate scale, reduces scale
Deng the adhesive ability in tube wall.
