Abstract

The invention discloses a plastic microchannel pipeline structure, a preparation method and a device. The plastic microchannel pipeline structure is a hollow pipeline, and a plurality of microchannels are evenly arranged on the wall surface of the pipeline around a central through hole along the circumference, and the microchannel structure has a large specific surface area. , which greatly strengthens the mass transfer and heat transfer performance of the structure itself; the preparation device of the microchannel pipeline structure includes a driving motor, a hopper, an extruder barrel, a data acquisition control system, an extruder head, a cooling water tank and a traction collection Coil device; the output shaft of the driving motor is connected to the tail of the screw in the extruder barrel through a pulley, the hopper is fixed above the tail of the extruder barrel, and the extruder head is fixedly connected to the front end of the extruder barrel , the cooling water tank and the traction and winding device are sequentially arranged in front of the extruder head; the invention is easy to operate, high in production efficiency and low in cost.

Description

technical field [0001] The invention relates to the technical field of new structural plastic pipes and processing, in particular to a plastic microchannel pipe structure and a preparation method and device. Background technique [0002] In recent years, with the development of micro-nano manufacturing technology and industry, new materials with micro-scale structures have become important basic material devices. Among them, most of them are new materials with microchannel structure. Due to their own structural characteristics, these micro-scale structure materials can bring advantages in application performance, so they are often used as media carriers, substrates or transmission pipes, etc. in the fields of microelectronics, biomedicine, aerospace and various transportation equipment. Special application value; in addition, it can also be used in food packaging, building noise reduction, electrical products, information engineering and sports equipment, etc. The well-kno...
