Plastic pipe production line compared with traditional production line

- Mar 05, 2019-

The production process of the plastic pipe production line is simple, the production process and the production equipment are relatively simple, and the pipe can be quickly molded by the hot press. Moreover, the use of waste plastics as the main raw material, the annual recycling amount of waste plastics in China is 6 million 18 million II屯, the cost is low, the mold tube itself can be completely recycled after being scrapped, and the plastic mold tube or other can be recycled after treatment. product. For the manufacturer, the production cost is reduced, and it is not necessary to pay the construction company the cost of processing the scrap bamboo and the wood mold tube, and the residual value of the plastic mold tube can be obtained. The production of steel mold tubes requires a large amount of mechanical equipment and cooperation with many operators. The productivity is only one-fifth of that of plastic mold tubes, and the cost is affected by the international iron ore import prices, which has been high. Wood mold tubes and bamboo plastic mold tubes are limited by the environmental protection policy and the natural production speed of plants. It is difficult to break through the bottleneck of production and cannot keep up with the rapid development of the current pipe industry.

The thermal expansion coefficient of plastic is very different from that of concrete, and the polymer material is incompatible with the material composed of concrete. After the pouring, the plastic mold tube will automatically separate from the concrete to be poured with the temperature change and the solidification of the concrete. Gently remove without knocking or using a release agent. The thermal expansion coefficient of steel and concrete is similar, and the steel mold tube and the newly poured concrete tend to be firmly bonded together, and the demoulding process easily damages the concrete. When the wooden mold tube is disassembled, it is easy to split and has a high loss rate.


The plasticity of the plastic is strong. The factory can adjust the shape of the lining of the mold tube through different mold forms according to the design requirements, and produce various plastic pipe production lines with different shapes and specifications. The surface of the mold tube can form a decorative pattern, and the exquisite wood grain, relief, marble, granite and other exterior finishes can be truly expressed on the concrete to create a concrete surface with more tube aesthetics. This combination of tube engineering and decorative engineering is a function that is difficult to achieve with other material tubes. The plastic mold tube is easy to apply in construction. The plastic material has the same anT and wood energy as wood and bamboo. It can be spliced and modified by drilling, nailing, sawing and planing. It is convenient to use.


The plastic pipe production line has good water resistance, acid resistance, alkali resistance and corrosion resistance, and flame retardancy is achieved by adding flame retardant materials. The wood mold tube and the bamboo plastic mold tube are not resistant to corrosion, are not flame retardant, and are easily absorbing water to cause deformation, and can not be recycled as a mold tube after being scrapped. Steel mold tubes can be recycled and have certain flame retardancy, but they are prone to water rust and reduce service life.


The plastic pipe production line belongs to polymer material, the pipe surface is smooth and smooth, the machined pipe surface flatness error can be controlled to within 0.3 ram, the thickness uniformity is good, the thickness tolerance can be controlled within -+0.3 mm, and it is suitable for pouring clear water concrete mold. The requirements of the pipe, the surface of the component after casting is smooth and beautiful, the secondary plastering process of the wall can be reduced, and the veneer decoration can be directly carried out, thereby effectively reducing the construction period. The thickness of the bamboo glue pipe under the year-on-year is allowed to reach 9-12mm, and the measurement method is generally 8 points around the tube. If the measured data of the 8 points meet the corresponding requirements, the thickness of the tube is corresponding. Level determination.

However, because the bamboo curtains and bamboo mats used in the plastic pipe production line are different from different regions of the farmer's hand IJjnI, there is a certain tolerance in the thickness of each piece of enamel. After multiple bamboo curtains and bamboo mats are stacked and hot pressed, the thickness tolerance is more obvious. Even if the thickness tolerance of the 8 points measured meets the standard, the parts outside the 8 points may exceed the tolerance range, which is a hidden danger in construction.
