The PP melt blown nonwoven production line is a polymer melt extruded from a screw extruder. The polymer is extremely stretched by high-speed hot air or other means to form very fine short fibers, which are aggregated to A web is formed on a roller or a screen curtain, and is finally reinforced by self-adhesion or thermal bonding. Its unique properties are widely used in mask filter materials, thermal insulation filling materials, medical health materials, wiping materials, etc. The finished product can pass the N95 standard as the core material of the mask.
Process of melt blown nonwoven production line
Polymer preparation --- Melt extrusion --- Metering pump --- Melt blown die head assembly --- Solution thin-flow drawing --- Fibber cooling --- Auxiliary network --- Electrostatic electret --- Reinforced finished product.
Melt-blown cloth is produced by melt-blown process. The equipment mainly includes: screw extruder, melt pump, screen changer, melt-blown device, winding device, air system (hot air blower and heater), etc. The function of the screw extruder is to melt the slice material; the role of the melt pump is to accurately measure, control the output and the fineness of the fiber, and continuously and evenly transfer the melt to the spinneret. The function of the screen changer is to filter out impurities in the melt so as not to block the spinneret holes. The function of the winding device is to pack the melt blown cloth into rolls. The function of the air system (hot air blower and heater) is to provide the temperature and pressure of the hot air used in the drawing of the spinning air stream.
