Nowadays, with the outbreak of various flu and viruses, masks have become a necessity of people's lives. Therefore, the raw materials of masks: non-woven fabrics and melt blown materials are now selling hot. Masks can protect people's health and cut off the transmission route to a certain extent.
The PP melt blown non wovens extruder 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 linePolymer preparation --- Melt extrusion --- Metering pump --- Melt blown die head assembly --- Solution thin-flow drawing --- Fiber cooling --- Auxiliary network --- Electrostatic electret --- Reinforced finished product
Melt-blown cloth is produced by melt-blown process. The Non-Toxic Sterile Mask PP Melt-Blown Fabric Making 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.

Advantages:
1.Energy-saving:
All main motors of machine use Variable Frequency Motor(AC),
eliminating three-phase asynchronous motors;
Variable Frequency Motor:
(1) Speed regulation is easy and energy saving.
(2) AC motor has simple structure, small volume, small inertia, low cost, easy maintenance and durability.
(3) It can expand output and achieve high speed and high voltage operation.
(4) Soft start and fast brake can be achieved.
(5) No spark, explosion-proof, and strong environmental adaptability.
2.High output:
Take "PP" material as an example, the PP material is tested on the customer's site, our machines' actual production output is 10%-20% higher than the same model in the market;
3.Simple installation:
The equipment is easy to install, only need to be connected to the inlet and outlet water, which can save 2 days of installation time.
