Abstract
The invention relates to a PE water supply pipe and a processing method thereof. The PE water supply pipe comprises a pipe extrudate outer layer and a pipe extrudate inner layer. The processing method of the PE water supply pipe comprises the steps of mixing of raw materials, processing at the extruder part, processing at the extrusion die head part, shaping and cooling, traction of pipes, cutting and stacking on a rack. The PE water supply pipe manufactured by the processing technology has relatively good low-temperature ductility, rigidity, ring stiffness and creep resistance, and cannot be deformed by gravity in the long-term use process, so that the product service life is prolonged and wide popularization is facilitated.
Description
Technical field
The present invention relates to a kind of PE supply pipe and processing method thereof, belong to plastic tube processing technique field.
Background technique
Along with the rapid growth that Chinese national economy is continual and steady, for cities and towns infrastructure construction provides good macro environment and broad space.Along with China is for the pay attention to day by day of environmental protection, governments at all levels of both the central and local governments have put into effect the policies and regulations of a series of water saving, pollution treatment protection of the environment.Water supply, water saving, draining and waste water control will become the emphasis of urban municipal construction from now on, and this provides market development space for applying of heavy-caliber plastic pipe.Because structured wall popes can conservation, reduce costs, therefore structured wall popes has become the main product of heavy caliber draining blow-off line.The U-PVC double-wall corrugated pipe that China is used for draining and blow-off line has good rigidity, the advantages such as price is low; But also there is the shortcoming of low temperature impact properties difference, be very easy to when north of china in winter is constructed damaged especially.And PE double-wall corrugated pipe has obvious advantage in low-temperature flexibility, but due to PE material behavior, its rigidity comparatively cement pipe is poor, comparatively PVC bellows is poor for the ring stiffness of tubing and creep resisting ability, in Long-Time Service process, easily by gravity deformation, affect product working life.
Summary of the invention
The object of the invention is to: for the defect of prior art, propose a kind of PE supply pipe and processing method thereof, the PE supply pipe made by this processing technology, there is low-temperature flexibility, rigidity, ring stiffness and creep resisting ability all good time not only, and in Long-Time Service process, because of gravity deformation, thus the working life of product can not be extended, contribute to the popularization of wide model.
The technical solution adopted in the present invention is: a kind of PE supply pipe, and the formula of described PE supply pipe is made up of the raw material of following quality proportioning:

In the present invention: a kind of processing method of PE supply pipe, comprises the following steps:
The first step, raw material mix: proportionally successively add in dry mixed machine with technique by other auxiliary materials such as PE raw material, color masterbatch, stabilizer, defoamer, antioxidants, remove moisture, material enters into the hopper of extruder after fully drying, mixing, and wherein dry temperature is less than 80 degree;
Second step, extruder part: when screw rod rotates in machine barrel, by PE mixture plasticizing pusher to head, thus reach compacting, melting, mixing homogenizing and realize be vented, dehydration object;
3rd step, extrusion die part: through the PE of compacting, melting, mixing homogenizing, have subsequent material to push die head to through screw rod, extrusion die is the critical component of product moulding;
4th step, sizing, cooling: PE Vacuum shaping Coolers is used for sizing, the cooling of section bar, the vacuum system for shaping and cool and water circulation system Vacuum shaping Coolers be equipped with, stainless steel casing, circulation water ring soaks cooling, Vacuum shaping Coolers is equipped with movable device and left and right, just regulates manual operating device;
5th step, tubing draw: tractor is used for extracting cooling hardening section bar from head continuously, automatically, frequency control of motor speed;
6th step, cutting: after position limit switch as requested cut to lengthen, carry out surface trimming, and time delay translation frame, carry out Production line, cutting machine for instruction, completes cutting overall process with fixed length work switching signal, run with section bar in cutting process and keep synchronous, cutting process is completed by electronic and pneumatic drive, and cutting machine is provided with dust exhaust apparatus, and the timely sucking-off of chip cutting produced also reclaimed;
7th step, piling bin: the action of tilting trestle stirring is controlled to realize by gas circuit by cylinder, tilting trestle is provided with a limit stoper, after cast-cutting saw cuts off section bar, section bar continues conveying, and after time delay, cylinder enters work, realize stirring action, reach discharging object, automatically reset through the time delay several seconds after discharging, wait for that next circulates.
After adopting technique scheme, beneficial effect of the present invention is: the PE supply pipe made by this processing technology, there is low-temperature flexibility, rigidity, ring stiffness and creep resisting ability all good time not only, and in Long-Time Service process, can not because of gravity deformation, thus extend the working life of product, contribute to the popularization of wide model.
