Description
Technical field
The present invention relates to the production method of a kind of continuous winding enhancing structure wall tube material He the tubing.
Background technology
Polyethylene winding structure wall pipe with hollow structure, because it is big with that can produce bore（In the market
Maximum caliber is up to 4 meters）, the small advantage of equipment investment, be widely used in municipal drainage, blowdown pipeline network construction.
At present, the manufacture method of polyethylene winding structure wall pipe generally has two kinds.
The first manufacturing process of aforementioned tubes.First by polyethylene of the first extruding machine extrusion with various hollow structures
Banding section bar, after vacuum water-cooled shaping, the circle equipped with more active rotation roller bearings is continuously regularly spirally wound on side by side
On shape forming cylinder.Constantly melted again from the second extruding machine to the polyethylene that molten state is squeezed between the banding section bar of spiral winding side by side
Glue, rolled through pinch roller, the adjacent regions of banding section bar by polyethylene melt adhesive together.Because banding section bar hollow structure not
Together, the polyethylene winding structure wall pipe with various hollow structure types is formed.It is interior such as polyethylene winding structure A type pipes
Rib helical bellows, winding bellows etc..But there is following defect in this technique：
（1）, banding section bar it is water cooled after tube wall is formed by melt adhesive again, can be due to ribbon type due to being cold and hot bonding
The temperature control deviation of material and have influence on the quality of cemented side seam；Simultaneously because melten gel and the non-concurrent cooling of banding section bar, cooling is received
It is not smooth enough that contracting also results in inner-walls of duct.
（2）, banding section bar it is water cooled after bend winding again, bending internal stress determines that such pipe structure is height-limited,
Tube wall the moment of inertia is small after shaping, is unfavorable for economically improving the ring stiffness of tubing.
Another manufacturing process of polyethylene winding structure wall pipe.First by the melting of the first extruding machine polyethylene extrusion
Banding melten gel, banding melten gel suitably cool down, and in semi-molten soft state, the banding melten gel is by continuously regularly wound side by side
On forming cylinder, because banding melten gel is in semi-molten state, mutually i.e. bonding is merged after overlap joint, forms real wall circle
Column tubing body.Polypropylene single wall ripple pipe is used simultaneously, polyethylene is coated through the second extruding machine compound die, due to polypropylene
Softening temperature is higher than polyethylene, so polypropylene single-wall corrugated pipe is notheated and collapsed.Coat the polypropylene list of molten polyethylene
Wall bellows is collapsed in a manner of spiral winding is pressed on melten gel band mutually overlaps on pipeline body fusion seam position, is coated on bellows
The polyethylene of molten and the melten gel band of two layers of overlap joint merge into each other and bond together, formed with circular hollow reinforcement
Polyethylene winding structure Type B pipe.Such a technique ensure that the quality of winding pipe cemented side seam, also due to inwall melten gel band cools down
Temperature close, make inwall smooth compared with the pipe material inner wall of the first technique productions.Such a technique has the disadvantage that, due to strengthening
It by polypropylene single-wall corrugated pipe is that the circular configuration that is formed of skeleton can not form benign support that muscle, which is, at the same single-wall corrugated pipe due to
By the high temperature of cladding PUR conduction, section can become ovalisation, cause the width of hollow reinforced rib to be more than height, also reduce
The structure height of tubing, tube wall the moment of inertia is small after shaping, be unfavorable for economically improving the ring stiffness of tubing.
It is above-mentioned to overcome it is therefore desirable to provide a kind of winding structure wall pipe and production method with hollow reinforced rib
The various shortcomings of technique and structure.
