Nano Micro technologies - incredible archipelagos of applications

Web material as regenerated cellulose films, filter, cigarette, tipping, roll-your-own RYO paper, transparent, coated special, bag or packing papers, bonded fabrics, spun bonded non-woven, technical textiles, fabrics, laminate with base weights from 20 g/m2 to up to 150 g/m2, up to 20 g/m2 LPDE coating films, are perforated electro statically nano, micro, or by laser (mechanical hot or micro needle) with micro or macro holes for wide range of application purposes.

Electrostatic NANO MICRO PERFORATION, based at micro discharging and sparking, Bluemlein and Plasma Tunnel effects with gas atomic ionization in Nanosecond time windows. The pores are statistically irregularly distributed with size ranges from 100 nm up to 80 ¼m diameter and analogically, under LASER or micro macro PERFORATION, arranged in diameter sizes from 60 up 200 ¼m, at best non-inclined holes und rows of holes of diverse arrangement comprehension.

For the human eye invisible electrostatic nano or micro perforations may be arranged in areas as well as in zones with specific distances within its web. Controlled pore sizes in wide ranges from 100 nm to 80 µm diameters by holes sequences up to 16 million pores per second and 0.1 bis 3 mJ discharge energy for each Pore.

Arrangements of zones are usually carried out in width from 2 to 6 mm and pore density of 15 up to 250 pores per cm2 whereas the perforation of areas results in pore densities of up to 5 million pores per m2. ESP perforations allow porosity levels from 80 to 2500 C. U., web widths from 100 to 2000 mm at web speeds of up to 500 m/min, depending on porosity and material consistency in relation to its ability to perforate.

Product properties with electrostatic perforation
One of the foremost postulation which can be applied to many application purposes and products containing bonded fabrics, bag or packaging papers, non-woven, etc. with gas or steam permeability but water impermeability. Further substrates or micro engineered membranes for micro filtration, fractionation, nanopattering, nanomembranes, nanophotonics, microbiology, catalysis, gas, alcohol, liquid or blood separation, battery separator foils or others are possible with ELECTROSTATIC NANO MICRO PERFORATION TECHNOLOGY, depends of material structures and perforability.

Which means pore sizes from 10 nm up to 10 µm diameter by up to 5 million pores per m2. This is due to the water’s greater surface tension as dyne level and hydrophobic property or wetability through the relatively small sizes of nano or micro pores. These and other advantages of the pores necessarily demand the application of the ESP perforation method because alternative perforation or processes are physically NOT feasible, too expensive or simply uneconomical and would not allow successful product applications.

To archive new nano or micro perforation demands IPM developed power electronics perforation units which working as upward converters with IGBT, BJT, MOSFET, FRETFET or HVFET for ultra short power pulses from 10 ns up to 20 µs, high current peaks up to 300 Amps, base frequencies up to 200 KHz on plug-in ferrite transformers to generate 50 Kilovolt to each sparking electrode. Patent grand DE10328937 for power electronics.

Outlook
The electrostatic nano or micro perforation usually applies within ranges of the refinement of fine paper, packaging webs, bonded fabrics, non woven, filter, bag or paper alternative material webs of most diverse kind especially when additionally or traditionally treating processes can not achieving the high require characteristics for physical, process or economical reasons.

Our highly modern, industrially approved electrostatic perforation technology which relied 24/7 operation can be integrated into existing rewinding, slitting, refining machines as well in entire production lines. Also, they can be used as completely independent perforation processes or machines. New ranges of applications will be made accessible as new NANO MICRO product properties with special features will be developed.
