Meltblown Air Heater
During the production of meltblown nonwoven, the electric air heater plays a key role. The compressed air from the blower or air compressor and air storage tank is sent to the air heater for heating. which is then heated until the desired temperature is reached. The air will then flow out of the heater at a fixed flow rate. The heat generated is evenly distributed and the efficiency of the heater is high. Temperature sensors can be used with any control to achieve the desired temperature range. The hot air makes the melted liquid polypropylene material ejected from the nozzle to form filaments (the nozzle contains hundreds of small holes) under the pressure.
► PROCESS
Screw extruder > filter > metering pump > heating system -> melt-blown manifold> web former > rewinding
► PRODUCTION PROCESS
The polypropylene is automatically sucked into the screw extruder by the vacuum feeder, which heats and melts the PP particles into the liquid state. The compressed air from the blower or air compressor and air storage tank is sent to the air heater for heating. The hot air makes the melted liquid polypropylene material ejected from the nozzle to form filaments (the nozzle contains hundreds of small holes) under the pressure. After that, the filaments are ejected horizontally to reach the web former, and then reach the winding equipment.
