Description
Technical field
The utility model relates to a kind of making apparatus and preparation method of plastic products, relate in particular to a kind of be used for combining the plastics bell-and-spigot pipe that is made into the band bell socket with plastic winding structural wall tube be used to extrusion die of making plastic winding structural wall tube and preparation method thereof.
Background technology
Plastics twine wall tube material be a kind of be primary raw material with high density polyethylene (HDPE) (HDPE) or polypropylene (PP), different according to rigidity and bore, extruding the cross section is the rectangle material base of certain size, twine mould through wrapping machine and twine, and form with the welding of fusion HDPE phase.It is a kind of flexible structure wall tube material with higher critical external compressive resistance ability.
Burying ground draining blow-off pipe field, the past is almost completely adopted rigidity tubing such as traditional steel pipe, cast iron pipe, pipe of cement and clay pipe.Along with China is for the raising of environmental protection consciousness in recent years, rigidity tubing is easy to leak the problem that pollutes public hazards and has caused attention.The dead load of road and the increase of dynamic load cause rigidity tubing interface leak, cause water resource to run off and polluted underground water.The concrete plug speed of application is slow, burying operation underground, to account for the road surface long-pending big, and this construction operation is incompatibility Traffic Development bustling with vehicles.Expect that from former there are problems such as pollution, power consumption in moulding in the concrete duct production process.There is following shortcoming in the rigidity pipe network in a word: 1. lack service life, be generally 5-10; 2. the chemically-resistant corrosion resistance is poor; 3. hydraulic performance is bad; 4. construction cost height, the cycle is long; 5. the pipeline globality is poor, easily leaks or the like.Therefore since the mid-term in 20th century, countries in the world particularly developed country are being carried out the exploitation of plastic pipe PP Pipe Compound and plastic conduit always and are being used.Plastic pipe has obtained successful development and use widely especially in developed country in Europe.
Plastic pipe is more and more favored with its Environmental Safety in life and commercial Application, is bringing into play important, irreplaceable effect.Substitute the trend that traditional piping material etc. has become the new century development with the environment-friendly plastic pipe.China is equally also at continuous various plastic pipes of research and development, though development relatively lag behind, in recent years along with the enhancing of china's overall national strength, the raising of living standards of the people, plastic conduit has obtained the development of advancing by leaps and bounds.Particularly since the eighties, the application of plastic pipe in municipal works and architectural engineering obtained obvious progress, not only quantitatively but also obtained very big development on kind and specification.Especially in recent years the Ministry of Construction had set up the national chemical building material coordination group pipelinerpiston committee and had guided, encouraged to greatly develop new green environment protection tubing from the perspective of policy, and the pipeline industry has obtained the development of advancing by leaps and bounds.
Through develop rapidly several years ago, at present, Material of Plastic Tube in Our Country has developed into that kind is more complete, production capacity is than the building material industry of tool scale, and main plastic pipe kind has: PVC-U pipe, PE pipe, PP-R pipe, ABS pipe, steel-plastics composite pipe, glass reinforced pipe or the like.At present, begun to take shape plastic tube industry with polyvinyl chloride (PVC-U) pipe, polyethylene (PE) pipe and polypropylene (PP-R) Guan Weizhu.Wherein polyethylene (PE) pipe is because the advantage of himself uniqueness is widely used in building water supply, and construction drainage, buried drain pipe, building and heating, appendix, industrial pipe, agricultural are with pipe etc.
High density polyethylene (HDPE) (HDPE) pipe has the branch of solid wall pipe and structured wall popes again.Though solid wall pipe function admirable, but cost is higher, waste material, particularly China is faced with the historic opportunities of development plastic tube (comprising heavy-caliber plastic pipe), but because the problem of economic rationality has hindered its development, this is that the plastic drain-pipe that diameter is very big will reach enough ring stiffness must bigger the moment of inertia because ring stiffness is a cube with diameter to be inversely proportional to.In other words, along with the increasing of diameter, raw-material consumption increase is very fast.Past does not have heavy caliber polyethylene to be on the one hand because poly strength ratio is lower at that time, on the other hand because the problem of manufacturing process yet.Afterwards, the polyethylene pipe proprietary material had obtained very big development, was significantly improved on the performance, after particularly high strength PE100 and PE112 and PE125 grade raw material come out, had just opened up road for the development of heavy caliber vinyl tube.My company finally researches and develops successful plastic winding structural wall tube by in the past few years constantly exploring new technology.But be made into plastic winding structural wall tube, corresponding apparatus and manufacturing process must be arranged.

The specific embodiment
Referring to Fig. 2, cooperate referring to Fig. 3, Fig. 4, the utility model is used to make the extrusion die of plastic winding structural wall tube, mainly comprises branch fluid 1, outer cylinder body 2, core 3, gland 4 and mouthful mould 5.
Cooperation is referring to Fig. 5, Fig. 6, Fig. 7, the main body of the branch fluid 1 in the utility model is a cylinder, cylindrical front end is provided with a conical head 11, rear end be linked in sequence flange 12 and melting charge inlet tube 13, the access road of inlet tube extends in the cylinder of flange inboard, and tell a plurality of melting charge subentries 14 towards periphery in the inboard radius vector of flange, be provided with many spirality channels 15 at cylindrical spaced surface, the rear end of each spirality channel is communicated with each melting charge subentry respectively, and the front end of each spirality channel connects at cylindrical conical head respectively.
The main process that adopts the utility model extrusion die to be used to make plastic winding structural wall tube is, high density polyethylene (HDPE) (HDPE) is in single screw tube of main extruder, after the high temperature heating and melting is extruded, enter extrusion die, through behind the extrusion die, form circular extruded stock in the extrusion die exit, behind vacuum sizing, finally form high density polyethylene (HDPE) (HDPE) winding structure wall pipe.
In process of production, high density polyethylene (HDPE) (HDPE) through the shearing of screw rod and mixing, after the high temperature heating and melting is extruded, begins to enter extrusion die in the screw tube of host machine part.Melting charge begins to enter extrusion die by the melting charge inlet 13 of minute fluid 1, the melting charge subentry 14 of under the active force of screw rod extruding, flowing through, enter spirality channel 15 afterwards, melting charge enters the melting charge outlet 7 that forms between gland 4 and core 3 and mouthful mould 5 then.Then enter the vacuum sizing device processing from exporting 7 melting charges that come out,, thereby form high density polyethylene (HDPE) (HDPE) winding structure wall pipe through the winding mould winding of wrapping machine.
In order to make material be unlikely in extrusion die, to cool off, on the outer wall of extrusion die, be added with heating element heater and temperature element.For the temperature to melting charge is monitored, make the tubing performance everywhere of working it out the same, heating-up temperature must be stablized, and on the outer cylinder body of extrusion die temperature sensor is housed, temperature sensor links to each other with temp controlled meter, by the heating of temp controlled meter by solid-state relay control heating element heater with stop.
Facts have proved that material is behind this extrusion die, mixing of materials is more even, and can form the desired sectional dimension of plastic winding structure wall pipe effectively.
