Abstract
The present invention discloses a kind of double-wall corrugated pipe manufacturing method, including the following steps: 1) inner wall tube melt is mixed in tank body, mixing is completed to be preheated, and outer wall pipe melt is mixed in stirring tank, is preheated after the completion of mixing；2) inner wall tube material after the completion of mixing preheating and outer wall pipe material are put into double screw extruder respectively and carries out mixing extruding and granulation；3) resulting inner wall tube particle and outer wall pipe are sealed preservation in the environment of -5~-15 DEG C；4) inner wall tube and outer wall tube particle after the completion of will be stored refrigerated be respectively heated again, and inner wall melt and outer wall melt are formed after heating；5) inner wall melt and outer wall melt are stretched, and carries out extrusion cooling in extruder respectively, and inner and outer wall is joined together to form by double-wall corrugated pipe using laminar manner.Step of the present invention is compact, can effectively improve the ring stiffness of double-wall corrugated pipe, and is unlikely to deform, and effectively improves service performance.
Description
Technical field
The present invention relates to double-wall corrugated pipe technical fields, and in particular to a kind of double-wall corrugated pipe manufacturing method.
Background technique
Double-wall corrugated pipe is a kind of novel tube with cyclic structure outer wall and smooth internal walls, and the beginning of the eighties is in Germany
It succeeds in developing first.By the development of more than ten years and perfect, via single Cultivar development to complete product line.At present
In production technology and using very mature in technology.Due to the cost of its excellent performance and relatively economical, in America and Europe etc.
Great promotion and application have been obtained in developed country.In China, the promotion and application of double-wall corrugated pipe are in uptrend
State stage, all technical reach using standard.
Double-wall corrugated pipe is a kind of novel tube with cyclic structure outer wall and smooth internal walls, is mainly used in work
For pressure in 0 .6Mpa large-scale water delivery, water supply, draining and ventilation below etc., general double-wall corrugated pipe is poly- with high density
Ethylene is raw material, has many advantages, such as light-weight, high pressure resistant, good toughness, poor larger with permanent deformation but there is also elasticity
The problem of, and it is buried if anti-microbial property it is also poor.
Summary of the invention
To solve the above-mentioned problems, the invention discloses a kind of double-wall corrugated pipe manufacturing methods.
The technical solution of the present invention is as follows: a kind of double-wall corrugated pipe manufacturing method, including the following steps:
1) inner wall tube melt is mixed 5~10 hours in tank body, mixing complete preheated, preheating temperature be 90~
100 DEG C, outer wall pipe melt is mixed 4~6 hours in stirring tank, is preheated after the completion of mixing, preheating temperature
It is 80~90 DEG C；
2) inner wall tube material after the completion of mixing preheating and outer wall pipe material are put into double screw extruder mix respectively
It squeezes and is granulated；
3) resulting inner wall tube particle and outer wall pipe are sealed preservation at least 7 hours in the environment of -5~-15 DEG C；
4) inner wall tube and outer wall tube particle after the completion of will be stored refrigerated be respectively heated again, and heating temperature is respectively 90~
110 DEG C and 80~90 DEG C, inner wall melt and outer wall melt are formed after heating；
5) inner wall melt and outer wall melt are stretched, and carries out extrusion cooling in extruder respectively, and using lamination
Inner and outer wall is joined together to form double-wall corrugated pipe by mode.
Further, the axial length of stretching is 40mm~90mm.
Further, inner wall melt and outer wall melt are in extruder, by the way of first pouring into outer wall melt.
Usefulness of the present invention: step of the present invention is compact, improves the double-wall corrugated pipe of production, Neng Gouyou through the invention
Effect improves the ring stiffness of double-wall corrugated pipe, and is unlikely to deform, and effectively improves service performance.
