Product Description:
Introduction to Parallel Twin Screw Barrel
A parallel twin screw barrel plays a pivotal role in the operation
of twin-screw extruder systems. It comprises two parallel screws
that rotate within a specially designed barrel.
Functionality and Design
These barrels are meticulously crafted to complement the screws,
enabling a seamless execution of various material processing tasks.
The screws can either rotate in the same direction (co-rotating) or
in opposite directions (counter-rotating).
Co-rotating configurations are commonly preferred for applications
such as plastic compounding and extrusion. The barrel is often
segmented to allow for convenient replacement and customization to
accommodate diverse processing needs.
Size and Application
The diameter of the screws can vary significantly, ranging from as
small as 12 mm in laboratory-scale extruders to exceeding 350 mm
for extensive industrial purposes.
Applications:
Plastic Compounding
Parallel twin screw barrels are extensively employed in plastic
compounding for blending various types of plastics. This process
involves mixing polymers with additives such as antioxidants, UV
stabilizers, and flame retardants to improve the characteristics of
the resulting plastic product. Additionally, these barrels are
utilized for creating polymer alloys, like blending polycarbonate
(PC) with acrylonitrile-butadiene-styrene (ABS) to combine the
desirable properties of both materials.
Masterbatch Production
Parallel twin screw barrels also play a vital role in the
production of masterbatches. By accurately blending a small
quantity of highly concentrated colorants or additives with a base
polymer, masterbatches are manufactured. These masterbatches are
later used to color or modify the properties of larger quantities
of plastic during the final manufacturing phase.
Plastic Recycling
In plastic recycling facilities, parallel twin screw extruders with
appropriate barrel designs are used to process recycled plastics.
These extruders can melt, clean, and compound the recycled plastic
materials, eliminating impurities and re-compounding them into
usable plastic pellets for further manufacturing.
