Plastic pipe production structure and docking process The PE pipe production line has a unique structure, high degree of automation, convenient operation and stable and reliable continuous production. The pipe produced by the plastic pipe production line has moderate rigidity, strength, good flexibility, creep resistance, environmental stress crack resistance and good heat fusion performance, and has become the first choice for urban gas transmission pipelines and outdoor water supply pipes. . The composition of the PE pipe production line: the pipe production line consists of a control system, an extruder, a head, a fixed cooling system, a tractor, a planetary cutting device and a turning frame. There are two extruders in each pipe production line. The main one extruder uses a strong conveying bushing and a high-efficiency screw, and the other smaller extruder is used to extrude the marking line. Mold and auxiliary machine: The machine head adopts the newly designed basket type head or spiral split type squeeze tube composite head, which has the characteristics of convenient adjustment and uniform discharge. The sizing sleeve adopts unique slotting process and water ring cooling to ensure The forming precision of the pipe. The PE pipe production line adopts PE high-efficiency screw and slotted barrel, and has strong water jacket cooling, which greatly improves the conveying capacity and ensures efficient extrusion; high-torque vertical structure reduction box; DC drive motor. The basket-type compound die for polyolefin processing guarantees high-efficiency extrusion stability while achieving minimum stress and highest tube quality at low melt temperatures. The high-efficiency double-cavity vacuum sizing technology and the spray cooling water tank are used to improve the yield of the pipe and meet the needs of high-speed production. With multi-crawler traction machine, the traction is even and stable. Each track is driven by an independent AC servo motor, and the drive technology controlled by the digital controller realizes accurate speed adjustment to achieve high synchronization. The high-speed, precision-designed cutting machine has a flat cutting section and a powerful suction device to minimize maintenance. Plastic pipe docking process: First, the principle of hot melt docking The plastic pipe is cut and heated by the machine tool to melt the section of the plastic pipe. Under a certain time pressure, the two plastic pipe sections are in contact with each other to achieve the purpose of welding. Due to the use of the body welding and the formation of the double-ring welding during the welding process, The inner and outer walls of the pipe form a reinforcing ring at the same time, and the weld strength is higher than that of the plastic pipe body. Second, the operation method steps 1. Prepare the working tools before starting the machine, fasten the fasteners of the whole machine, and whether the power supply meets the requirements of the machine (AC220, AC380). Milling cutter, heating plate (adjustment setting temperature 200-220 °C), whether the clamping tile is consistent with the pipe, whether the machine test is flexible and reliable. 2. Turn on the power and turn on the heating plate to heat to 200-220 °C. 3. Adjust the pipe. Place the plastic pipe or fitting into the matching lining and place the milling tool in it so that the pipe or pipe is equidistant from the milling cutter (approximately 30-40mm). Take out the milling cutter disc, tighten the clamps, and adjust the center of the two pipes or fittings to be coaxial. (The circumferential deviation must not exceed 20% of the body). 4. Butt hot melt. Put in the electric heating plate, push the two pipes or pipe fittings, and the molten edges on both sides of the electric heating plate are uniformly dissolved 2mm. At this time, the pressure is relieved to 0Mpa, and then the pressure relief is tightened 3, and the sides of the electric heating plate have a melting edge of 4mm (pause time 35) -60 seconds), take out the hot plate, and quickly push the hydraulic cylinder to close the two pipes under pressure (no more than 2Mpa below Φ250, no more than 3Mpa to adjust the pressure regulating valve), with appropriate sides, cooling time is determined by the wall thickness of the pipe For example, Φ110× 5.3mm, which is 5.3×1.5=7.95 minutes, remember to not use water to cool the forced cooling, finally remove the clamping screws and take out the butt pipe or fittings. The docking step is completed. Third, the characteristics of plastic pipe: As an important part of chemical building materials, plastic pipe is widely accepted by customers for its superior performance, sanitation, environmental protection and low consumption. It mainly includes UPVC drainage pipe, UPVC water supply pipe, aluminum-plastic composite pipe, polyethylene (PE). These are the water pipes. The pipe production line consists of a control system, an extruder, a head, a fixed cooling system, a tractor, a planetary cutting device and a turning frame. There are two extruders in each pipe production line. The main one extruder uses a strong conveying bushing and a high-efficiency screw, and the other smaller extruder is used to extrude the marking line. When the plastic pipe production line fails, the surface of the plastic pipe will be rough, the internal vibration ring will appear, and there will be no vacuum. Therefore, it is necessary to eliminate the failure of the plastic pipe production line in time to improve the product quality.
Engineered wood flooring trends include the following:
1. Environmental protection materials: With the improvement of people's awareness of environmental protection, more and more consumers choose to use environmental protection materials. Engineered wood flooring is a combination of wood and man-made materials. Compared with solid wood flooring, the wood used is more economical and can reduce the cutting of natural forests.
2. High-quality appearance: Engineered wood flooring has the natural beauty and texture of solid wood flooring, and it can also create more diversified appearance effects through processing technology. Consumers are increasingly demanding the appearance of the floor, Engineered wood flooring can meet their needs for high-quality appearance.
3. Durability and wear resistance: Engineered wood flooring adopts a multi-layer structure to make it have high durability and wear resistance. This makes it suitable for use in high-traffic areas such as kitchens and hallways in commercial premises and homes.
4. Convenient installation and maintenance: Engineered wood flooring is more convenient to install than solid wood flooring. It can be installed by locking system or adhesive, reducing installation time and cost. At the same time, Engineered wood flooring is also easier to maintain than solid wood flooring, and only needs regular cleaning and maintenance.
5. Diversified design and color choices: Engineered wood flooring provides a rich variety of design and color choices to meet consumers' needs for personalization and customization. From classic wood grain design to modern stone and metal grain design, consumers can choose the right floor according to their own preferences and home style.
In general, the popular trend of Engineered wood flooring is to develop in the direction of environmental protection, high quality, durability, convenient installation and maintenance, and diversified design and color selection. These trends reflect changes in consumer demand and preferences for flooring.
