Qingdao Tongsan Plastic Machinery Co., PE double-wall corrugated pipe production line pvc double wall corrugated pipe production line, HDPE double wall corrugated pipe equipment, PVC double-wall corrugated pipe production line to high-quality production of double-wall corrugated pipe, corrugated forming system It plays a vital role in the production of double-wall corrugated pipe all the key technology is concentrated here. Corrugated forming system can be divided into segments corrugating machine, Corrugated molds, extrusion die and cooling and shaping three parts. Look at the role of corrugating machine pp double-wall corrugated pipe production line, corrugating machine is to be installed thereon corrugating module continuous and stable operation, and to provide the necessary corrugating vacuum function and cooling function. As mentioned earlier, because of the high ring stiffness, low-cost double-wall corrugated pipe inevitably requires both high and wide peak shape, and the current domestic basically a "positive pressure inside and outside negative" ripple molding method in which a double-walled outside the bellows is compressed and the dual role by vacuum molding corrugated. Corrugated molds to make continuous and stable operation, the orbit module designed machine is especially important in the molding, excellent corrugating machine module orbit design can greatly improve the life of the machine, and the pros and cons, although track design can not visually see, but it can run through the machine drive motor module power level indirectly reflected. Excellent track design should be minimal friction. Less friction, lower wear, longer life. Because friction smaller corrugating machine drive motor power is smaller, so judging module running track machine design is reasonable, just look at the drive module running motor power that is known. In the production of double-wall corrugated pipe, corrugated molding module also plays a vital role, first because Corrugated molds directly determine peak shape, the second is due to the manufacturing process of corrugating module directly affect the quality of the pipe, at present, for large-diameter pipe production modules are basically aluminum alloy, first cast molding, and machining. General requirements for polyethylene (PE) performance has a melt flow rate (MFR) oxidation induction time (OIT) and density. The melt flow rate reflects the size of the molecular size, in general, a melt flow rate that is conducive to a large molding material, and improve production efficiency. But not too large, too large a greater impact on ring stiffness, the choice of 0.8-1.5g / 10min (190 ℃, 5kg) is appropriate. Oxidation induction time determines the oxidative damage of time, the requirements for the use of the 50th anniversary of the bellows, the control of raw materials, good oxidation induction time is the key to whether the 50-year life of the guarantee. GB / T19472.1-2004 clearly states, bellows material oxidation induction ≥20min (200 ℃). For medium and high density polyethylene, the performance can be adjusted by changing the density. Because we know relatively low density polyethylene may extend the time of its brittle failure. Four, HDPE pipe penetration is far lower than the cement pipe, less than 2%, will not cause secondary pollution of groundwater; cement pipe inelastic, although with a gasket, but the sealing effect is poor, especially construction workers due to the cement pipe heavy, well construction, regardless of socket effect simply lead apron useless double-wall corrugated pipe production line, so that the pipe penetration increase five, HDPE pipe long service life, more than 50 years. Safety in the period PE pipe for more than 50 years, it has been proved not only international standards and new international, and has been proven in advanced countries. Cement pipes all over the country by the water leakage resulting in land subsidence, the interface fracture, had to be replaced within a few years the instance. Six HDPE pipe inner surface is smooth, with no sign of nuclear power, not scaling. Cement pipes easy to scale, after scaling, so that the diameter narrowing, affecting traffic through seven, HDPE light weight, easy to transport and install large-diameter double-wall corrugated pipe production line, no loss; pipe quality cement weight, not easy to transport and install, and easy to wear and tear during transportation and installation. pe double-wall corrugated pipe production line | double wall corrugated pipe production line | with three presses provided by Qingdao Tongsan Plastic Machinery Co., Ltd.
