High-voltage electrospinning machine with coaxial nozzle and drum collector
This high-voltage electrospinning machine
is for preparing ultra-fine fibers with the diameter of 20-1000nm by using a
polymer solution or molten liquid in a strong electric field. The nanofiber has
a high specific surface area, small diameter, and large porosity. There are
more than 100 kinds of polymers could be used as raw materials, and also
protein, collagen, organics (PEO, DNA, PAA, PLA, nylon, polyester, acryl resin,
PVA, PS, PAN, peptide, cellulose).
Main parts: liquid supply device, high
voltage power supply, spinning nozzle, collecting device
1. Liquid supply device: uses two
professional scientific research syringe pumps, can provide liquid with
continuously stable flow, and the liquid supply speed is adjustable to meet the
needs of different spinning solutions.
2. High voltage power supply: can provide a
stable electric field for a long time, electric field strength standard 0~30KV.
3. Spinning nozzle: Coaxial nozzle, which
is composed of two inner and outer layers of two needles with different
diameters. It can be used to make hollow-structured nanofibers, shell-core
structured nanofibers, micron fibers, etc. Using coaxial spray technology,
polymers with different properties can be combined to make nanofibers with
special properties. In addition, some polymers with poor spinning performance
can also be prepared into special nanofibers by coaxial spray technology. In
this case, the polymer with poor spinnability should be used in the outer layer
of the coaxial nozzle, and the polymer with good spinning performance as the
inner structure. Besides, the support of spinning nozzle is adjustable for
obtaining the best spinning distance and non-woven fabrics with different
widths, which can perform automatic reciprocating motion parallel to the
collector, effectively improve the uniformity.
4. Collecting device: standard
configuration is one drum collector. Other plate collectors are optional.
