Mask Melt-blown Cloth Spinneret Die Mould 1. overview and principle of meltblown cloth equipment the melt-blown method is a method for preparing fibers by blowing polymer melts with high-temperature and high-speed airflow to rapidly draw them. (melt-blown cloth extruder, melt-blown cloth equipment, melt-blown cloth production line) after the polymer chips are heated and pressed into a molten state by a screw extruder, they reach the spinneret hole at the front end of the nozzle through the melt distribution flow path, and after extrusion, they are refined by two converging high-speed and high-temperature air flows to refine . the refined fibers are cooled and solidified on the screen device to form a melt-blown nonwoven fabric. 2. components of meltblown cloth equipment meltblown heads, automatic charging system equipment components, ultrasonic cleaning machines, air heaters, centrifugal fans, screw extruders, meltblown web forming machines, meltblown offline winding machines, meltblown offline slitting machines and other key equipment. 3. the core components of meltblown cloth equipment spinneret the spinneret for melt spinning is a representative spinneret for the manufacture of synthetic fibers such as polyester and nylon. the thermoplastic resin is heated and melted, extruded through the spinneret in air or water at a certain speed, and cooled spinning method of solidifying into fibers the most core technology is the small nozzle on the spinneret. this nozzle not only has a small size of only 0.15mm, but also needs to process a complex hole pattern on such a small nozzle. the processing is extremely difficult, and the nozzle processing process requires months. if the processing accuracy is not high, the melt-blown cloth finally produced will not meet the corresponding technical requirements, which will affect the protective performance of the mask. structure of melt-blown cloth spinneret according to the shape of the spinneret, the structure of the spinneret can be divided into three forms: round, sector and rectangle. at present, round and rectangular plates are mostly used at home and abroad. to suit different chemical fiber spinning occasions, the round spinneret is divided into flat type, flange flat type, flat ring, flange ring, etc .: the rectangular spinneret is divided into flange rectangle and flange groove rectangle, etc. , mostly used for spinning short fibers with many holes. meltblown cloth spinneret structure
