Abstract
A glass fiber reinforced hollow wall polyethylene wound pipe is formed by spirally winding polyethylene hollow rectangular plastic pipes and welding the polyethylene hollow rectangular plastic pipes through hot melt glue. In spirally winding and welding with hot melt glue, at least one polypropylene/polyethylene (PP/PE) composite coating long glass fiber beam, and the PP/PE composite coating long glass fiber beams and the hot melt glue are adhered between two adjacent polyethylene hollow rectangular plastic pipes. Compared with pipes with the same specification, the weight of each meter of the glass fiber reinforced hollow wall polyethylene wound pipe is reduced by 20-30% so as to greatly reduce production cost. Glass fibers are well embedded in polyethylene pipes, the glass fiber reinforced hollow wall polyethylene wound pipe is suitable for large-diameter high-annular-rigidity plastic pipelines (with DN more than 1500 and SN more than 16 KN/m <2>), and the glass fiber reinforced hollow wall polyethylene wound pipe is suitable for environments of plane runways, railways and the like with high requirements.
Description
Technical field
The utility model relates to a kind of tubing, and particularly a kind of glass strengthens the hollow wall polyethylene wound pipe.
Background technique
Traditional drainage pipe is mainly with cement pipe and clay Guan Weizhu, and the ubiquity power consumption is high, easily produce characteristics such as environmental pollution; Also there is following shortcoming simultaneously: 1. lack working life, be generally 5-10; 2. the chemically-resistant corrosion resistance is poor; 3. the hydro science performance is bad; 4. construction cost height, the cycle is long; 5. the pipeline integrity is poor, easily leaks or the like.Since mid-term in 20th century, the exploitation of plastic tube PP Pipe Compound and the exploitation of plastic pipe production technology are being carried out in countries in the world particularly developed country always.
Bury ground plastic draining pipeline system with its inner wall smooth, light weight, interface adopts socket joint to flexibly connect, its good seal performance, flexible good, should not be damaged, convenient and fast connection, need not employ large-scale hanging device in the work progress, it is compared with the construction of clay pipe with traditional cement pipe has the saving of labor, saves time raising speed of application easy to connect, reduce labor intensity, plurality of advantages such as long service life have demonstrated fully its superiority, are easilier accepted by people.
In recent years, it is very rapid in China's development to bury ground plastic draining pipeline, has become the progressively application that the focus, particularly heavy caliber of an investment bury the ground plastic drain pipe, and the drainage works for China provides a good pipe-line system undoubtedly.In addition, the construction that has also clearly proposed to strengthen drainage pipeline networks in " 12 " of country planning all provides excellent opportunity for the development of burying the ground plastic drain pipe.But also there is certain problem in heavy caliber pipe self.As everyone knows, the ring stiffness of tubing and the cube of caliber are inversely proportional to, with the modulus of material, be directly proportional with the moment of inertia of tubing.When the tubing bore increased, the weight that only improves tubing can't solve the problem that the tubing ring stiffness reduces fully.On the one hand, the construction party that increases to of tubing weight has worn more inconvenience, the more important thing is to make the cost of production of tubing increase greatly, and this also becomes the difficult problem that the many manufacturers of restriction can't produce heavy caliber pipe.
The model utility content
The purpose of this utility model exactly in order to solve the problem that above-mentioned prior art exists, provides a kind of glass to strengthen the hollow wall polyethylene wound pipe.
In order to achieve the above object, the utility model has adopted following technological scheme: a kind of glass strengthens the hollow wall polyethylene wound pipe, be welded through the spiral winding and with hot melt adhesive by polyethylene hollow, rectangular plastic tube, in the spiral winding and in the hot melt adhesive welding, be wound with at least one compound coating roving glass fiber of PP/PE bundle synchronously, the compound coating roving glass fiber of this PP/PE bundle is bonded between the two adjacent polyethylene hollow, rectangular plastic tubes with hot melt adhesive;
The compound coating roving glass fiber of described PP/PE bundle is composited by continuous glass fibre tow, acrylic resin and polyethylene resin, described continuous glass fibre tow is evenly dispersed in the acrylic resin and by acrylic resin and wraps up, and described polyethylene resin is coated on outside the acrylic resin; Described continuous glass fibre tow twines yarn by the non-twist glass fibre of alkali-free and forms through coupling agent treatment.
The compound coating roving glass fiber of the PP/PE of described synchronous winding bundle is the 1-100 root, and the many compound coating roving glass fiber of PP/PE bundles are dispersed between the hollow, rectangular plastic tube.
The compound coating roving glass fiber of the PP/PE of described synchronous winding Shu Weisan root, the three compound coating roving glass fiber of PP/PE bundles are dispersed in three places, upper, middle and lower between the hollow, rectangular plastic tube.
The diameter of the compound coating roving glass fiber of described PP/PE bundle is 1-5mm.
Glass of the present utility model strengthens hollow wall polyethylene wound pipe tubing, compares with same specification tubing of the same type, and every meter substance of tubing has reduced by 20～30%, thereby makes cost of production obtain very big reduction; On the other hand, glass in the utility model is embedded in the polyvinyl piping materials well, with polyethylene good compatibility is arranged, play desirable enhancing effect, more be applicable to the production of heavy caliber high ring rigidity plastic pipe (DN1500 and above, SN thereof can reach more than the 16KN/m2), every meter weight of tubing need not to increase the requirement that too much can satisfy ring stiffness specification commonly used; The particularly important is, tubing of the present utility model is suitable for the environment that runway, track for a train etc. have requirements at the higher level.
