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
is10%-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.
The resin chips are fed into a screw extruder, heated and melted
and extruded from a nozzle. The polymer melted at the exit of the
die is subjected to high speed. At the same time, cold air comes
from both sides of the die to cool and solidify the fibers to form
ultra-fine short fibers. The effect of air flow, these short fibers
are aggregated on the fiber collection device to form a web or
core.The melt-blown process is a one-step process from
thermoplastic resin slicing to making a fiber mesh belt (cloth /
core tube).Therefore, the process is short, the product is formed
in one step, and the production efficiency is high.By adjusting the
combination of meltblown processes, different fiber structure (such
as fiber diameter (0.5 ~ 3um), web pore size,etc.) can be achieved.
The meltblown process is suitable for a wide range of raw materials
and is suitable for processing variousmaterials such as
polypropylene, polyester, and nylon. At present, polypropylene
materials account for more than 95%.
