Description
Technical field
The present invention relates to a kind of HDPE steel band reinforced spiral ripple pipes and its production technology, belong to plastic pipe process technology
Field.
Background technology
With the continual and steady rapid growth of Chinese national economy, good macroscopic view is provided for cities and towns infrastructure construction
Environment and broad space.As China has put into effect a system for the pay attention to day by day of environmental protection, governments at all levels of both the central and local governments
Row water saving, the policies and regulations of pollution treatment environmental protection.Supply water, economize on water, draining and waste water control will turn into urban municipal construction from now on
Emphasis, this provides market development space for the popularization and application of heavy-caliber plastic pipe.Because structured wall popes can save raw material,
Cost is reduced, therefore structured wall popes have become the main product of heavy caliber draining blow-off line.China is used for draining and blowdown
The HDPE double-wall corrugated pipes of pipeline have a good rigidity, the advantages such as price is low；But also have the shortcomings that low temperature impact properties difference, especially exist
Breakage is very easy to when north of china in winter is constructed.And PE double-wall corrugated pipes have obvious advantage in low-temperature flexibility, but due to PE materials
Expect characteristic, its rigidity is poor compared with pipe of cement, and the ring stiffness and creep resisting ability of tubing are poor compared with HDPE bellowss, in long-term use of process
In, easily by gravity deformation, influence product service life.
The content of the invention
It is an object of the invention to：A kind of the defects of for prior art, it is proposed that HDPE steel band reinforced spiral ripple pipes
And its production technology, with the processing technology make HDPE steel band reinforced spiral ripple pipes, not only when have low-temperature flexibility, just
Property, ring stiffness and creep resisting ability are preferable, and during long-term use, will not be because of gravity deformation, so as to extend
The service life of product, contribute to a wide range of popularization.
The technical solution adopted in the present invention is：The HDPE steel band reinforced spiral ripple pipes, including following parts by weight
Raw material：
In the present invention：Above-mentioned raw materials are mixed according to formula rate, the moisture in raw material is removed, gathers high density
Ethylene raw semigel, loose powder is formed, makes auxiliary agent dispersed in high density polyethylene materials, wherein mixture temperature
For：Mixed 80~120 DEG C of the temperature of heat, cold mixed 70~80 DEG C of temperature.
In the present invention：A kind of production technology of HDPE steel band reinforced spiral ripple pipes, comprises the following steps：
The first step, raw material mixing：By high density polyethylene materials, color masterbatch, stabilizer, defoamer, antioxidant etc. its
He is proportionally successively added in dry mixed machine auxiliary material with technique, removes moisture removal, material is through fully drying, being entered after mixing
The hopper of extruder, wherein dry temperature is less than 70 degree；
Second step, heat are mixed：The mixed purpose of heat be each component in material is sufficiently collided in the presence of blade, rubbed,
Convection current, each component is reached farthest scattered, and material is heated up, reach preplasticizing, the mixed temperature general control of heat exists
95 DEG C or so, it is noted that the accuracy of hot mixing, the mixed temperature accuracy of Timing measurement heat, prevents the mixed temperature of heat in production process
Out of control and material is burnt out；
It is 3rd step, cold mixed：It is cold it is mixed be sufficiently to cool down high-temperature material, avoid high density polyethylene (HDPE) material because for a long time compared with
Decomposed in the environment of high-temperature, so that during tube forming, the materials degree of plasticification heterogeneity of batch mixing, production each time is not easy steady
It is fixed；Simultaneously cold be mixed with helps to prevent material conglomeration, improves blanking, steady extruding amount, general cold mixed temperature control at 38 DEG C or so,
At this temperature, material can be deposited more than 24 hours, and putting material situation is good, and main frame torque ripple is small, and production is stable；
4th step, extrusion：Extrusion is the core procedure of the shaping of plastic pipe；The hardcore of extrusion molding is extrusion
Machine, and " heart " of extruder is screw rod and machine barrel, whether screw rod and the fine or not and supporting of machine barrel quality can rationally directly affect
To the plasticizing capacity of board, so, for different extrusion equipments, unified formula should not be used, that is, being formulated design should be according to machine
The plasticizing capacity of platform and determine；Principle is that degree of plasticification control is advisable 70~75% or so, and the setting of temperature can adopt " saddle
The setting scheme of type ", both temperature settings at machine head port mould are in " saddle-shape " square cloth from machine barrel to merging core, then from merging core,
Using this setting, thermograde is larger, and melt pressure is big, and product is more closely knit after shaping, and impact strength, hydraulic pressure resistant intensity are high.
It is noted that main frame electric current will be controlled 50~60% or so in process of production, and it is unsuitable too high or too low, otherwise can shadow
Ring and become apparent under main frame vacuum, particularly fuselage screw rod abrasion more serious situation, in addition can also cause to plastify
Excessively or plasticizing is bad；
5th step, sizing, cooling：High density polyethylene (HDPE) Vacuum shaping cooler is used for the sizing of section bar, cooling, and vacuum is fixed
Vacuum system and water circulation system for sizing and cooling is housed on type cooler, stainless steel casing, circulates water ring immersion cooling,
Equipped with movable device and left and right, high high adjustment hand gear on Vacuum shaping cooler；
6th step, tubing traction：Hauling machine be used for it is continuous, automatically will cool down the section bar being hardened and drawn at head
Come, frequency control；
7th step, cutting：After travel switch length control as requested, surface trimming, and the translation frame that is delayed are carried out, is carried out
Production line, cutting machine complete cutting overall process using fixed length work switching signal as instruction, run and protect with section bar in cutting process
Synchronization is held, cutting process is completed by electrical and pneumatic driving, and cutting machine is provided with dust exhaust apparatus, chip caused by cutting is inhaled in time
Go out and reclaim；
8th step, stack：The action of tilting trestle stirring is realized that tilting trestle is spacing provided with one by cylinder by gas circuit control
Device, after saw cutting section bar is cut, section bar continues to convey, and after delay, cylinder enters work, realizes that stirring acts, reaches
Discharging purpose, automatically reset after discharging through the several seconds that is delayed, wait subsequent cycle.After adopting the above technical scheme, the present invention's has
Beneficial effect is：With the processing technology make the double-wall corrugated multiple tubes of mining HDPE, not only when there is low-temperature flexibility, rigidity, ring
Rigidity and creep resisting ability are preferable, and during long-term use, will not be because of gravity deformation, so as to extend product
Service life, contribute to a wide range of popularization.
