Nano Micro perforation - an archipelago of technical possibilities

Nano Mikro Perforation – ein Archipel von technischen Möglichkeiten

optical online porosity and dyne - surface tension - control at material webs

Nano Mikro Technologien für Materialbahnveredelungen
Zur Ventilation oder Atmungsaktivierung werden Zigaretten-, Mundstückbelag-, Filter-, beschichtete Spezial-, Kraft-, Sack- oder Verpackungspapierbahnen, Vliesstoffe, spun bonded nonwoven, technische Textilien, Fabrics und Laminate mit Flächengewichten von 20 g/m2 bis zu 140 g/m2 elektrostatisch ESP Nano, Mikro oder Laser- oder mechanisch Mikro oder Makro perforiert. Unter elektrostatischer ESP NANO MIKRO PERFORATION sind statistisch unregelmäßig verteilte, in der Größe, wenn gewünscht mit bis zu 40 % variierende und analog hierzu unter LASER Mikro oder Makro PERFORATION, gleichmäßig angeordnete und im Durchmesser etwa gleichgroße, nach Möglichkeit runde, gradfreie Löcher und Lochreihen verschiedenster Anordnung zu verstehen.

Im bis 1.5 mm weiten atmosphärischen Elektrodenspalt erfolgt durch Blümlein- und dielektrisch geförderte Mikroendladungen mit Filametierung die Erzeugung eines Plasmentunnels zum ionisierten Funkenstreckenkanal im Nanosekundenzeitfenster. Mit jeder Entladung und Deionisation entsteht für die im Elektrodenspalt relativ schnell durch bewegte Materialbahn eine elektrostatische Nano oder Mikroperforation mit sehr präzise gesteuerten Energieanteilen von 0.1 bis 3 mJ pro Pore, die mit dem menschlichen Auge unsichtbar ist und vollflächig wie auch zonenförmig in bestimmten Abständen über die Bahnbreite verteilt sein kann.

Erzielbaren Lochgrößen sind im Durchmesserbereich von 100 nm - 80 µm bei Lochsequenzen von 1.5 – 16 Million Poren pro Sekunde möglich.

Zonenanordnungen sind in Breiten von 2 bis 6 mm und Porendichten von 120 bis 250 Poren pro cm2 erreichbar, wobei Flächenperforationen Lochdichten bis zu 3 Million Poren pro m2 generieren.

ESP Perforationen ermöglichen Porositätsbereiche von 80 bis 2500 C.U. ( Coresta Unit ml/2cm2/min ), Bahnbreiten von 100 bis 2000 mm bei Bahngeschwindigkeiten bis zu 500 m/min, abhängig von der Porosität und Materialkonsistenz zur Perforierbarkeit.

Anforderungsprofile

Kardinalforderungen die für viele Applikationsbereiche und Produkte mit Vliesstoffen, Sack- oder Verpackungsbahnen mit einer Gas- oder Wasserdampfdurch- aber Wasserundurchlässigkeit verbunden sind, finden sich im Anwendungsbereich der ELEKTROSTATISCHEN NANO MIKRO PERFORATIONSTECHNIK wieder, da Wasser oder andere Flüssigkeiten die relativ kleinen Nano oder Mikroporen von z.B. < 0.5 - 5 µm Durchmesser aufgrund der hydrophoben Oberfläche nicht penetrieren kann.

Diese und weitere physikalische Vorteile der kleinen Poren fordern regelrecht den Einsatz der ESP Mikroperforationsmethode heraus, da Erfüllungen zur Atmungsforderung und Wasserdampfdurchlässigkeit z.B. nach der ASTM E96-80 oder E96-84 Messmethode mit 100 – 800 g/m2/Tag mit anderen Perforations- oder Prozessverfahren nur äußert schwierig machbar, zu teuer, zu unwirtschaftlich oder bei derart hohen Lochdichten technologisch nicht erreichbar sind.

Resumee

Nur die elektrostatische Mikroperforation ermöglicht durch eine sehr präzise Energieeinkopplung, Filamentierung, dielektrisch geförderte Mikro- und Plasmenentladung eine nano oder mikrofeine Ventilation für Packmitteln mit Barriereeigenschaften, Atmungsaktivität von Massenprodukten, industriellen oder medizinischen Nano oder Mikromembranen, Vliesstoffe und insbesondere Papierbahnen verschiedenster Art bei großen Bahnbreiten und Geschwindigkeiten. Dieser Trend wird sich für spezielle Produkteigenschaften und Anwendungen weiter fortsetzen.

Durch Neuentwicklungen in der elektronischen Leistungsschaltungstopologie mit IGBT, BJT, MOSFETS, FRETFET oder HVFET zur Erzeugung sehr feiner, stromgesteuerter Hochspannungsentladungsimpulse im Zeitfenster von 10 ns bis 15 µs und einzelner Ladungsenergien von 0.1 bis 3 mJ hat die Nanotechnologie zur Submikroperforation auch im diesem Bereich der Feinpapierveredelung und Verpackungsindustrie Einzug gehalten. Patenterteilung DE10328937.

Kunststofffolien wie PE, PP, LDPE, BOPP, EVA HDPE lassen sich auch zukünftig besser mit hot oder micro needle oder anderen mechanischen sowie mit Gasendladungs- oder Festkörperlaser gesteuert perforieren. In diesem weiten Applikationsspektrum ist es denkbar auch dahingehend entwickelte, angepasste Laserperforationssysteme für Breitbahnen bis zu 2000 mm und Lochsequenzen über 3 Mil./Sek. einzusetzen.

Konventionelle Laserperforationstechnik

Durch gepulste, fokussierte Laserstrahlen sind mit im Markt angebotenen Anlagen Lochgrößen von 60 - 200 μm bei Lochdichten von typischer Weise 10 – 30 Löcher pro cm, Lochsequenzen von 100.000 bis 300.000 Löcher pro Sekunde, bei maximal 16 oder 32 Laserlochreihen über die Bahnbreite verteilt, möglich. Deren Porositätsbereiche bewegen sich zwischen 100 – 3000 C.U., in der Regel mit Bahnbreiten von 100 – 500 mm bei Bahngeschwindigkeiten bis 600 m/min, abhängig von der Porosität und Materialkonsistenz zur Perforierbarkeit.

Laserperforationstechniken von IPM

Mit Entwicklung eines Dual Hochleistungslasermultiplexers und optischen Eingangsleistungen bis zu 8 KW ( fast flow or SLAB Laser mit 10.6 μm Wellenlänge ) ist es erstmalig gelungen, bis zu 200 separierte optische Laserstrahlausgänge zu realisieren mit denen nunmehr Papier Perforationen in breiten Bahnen bis zu 2000 mm möglich sind.

Dies jetzt mit Lochsequenzen bis zu 2 Millionen pro Sekunde, Lochgrößen von 60 - 100 µm, Lochdichten von typisch 10 – 30 Löcher pro cm, Porositäten im Bereich von 100 bis 1000 C.U., Bahngeschwindigkeiten bis zu 400 m/min und non stopp 25.000 Meter Jumbo Rollenbetrieb auf der Ab- und Aufwicklung, was eine jährliche Ausbringung von bis zu 2000 Tonnen von laserperforierten Feinpapieren an dieser high Automationsproduktionsmaschine LPM-1 bei exorbitant geringen Papierausschuss von < 1% und QUAFÖ Qualitätszertifizierung einer jeder Produktionsrolle ermöglicht. Patenterteilung DE102004001327.

Hierbei ist das optische online Porosität POROVISION Messsystem OPSS-1 zur präzisen Positionskontrolle aller Laserperforationslinien sowie die permanente Erfassung der Porositätsprofile ein integraler Bestandteil der ISO Qualitätskontrolle und Datenauswertung zum Ende einer jeden Produktionsrolle. Patentanmeldung DE10251610 und Erteilung in China 200310104764.

Eine weitere Entwicklung in der Micro Laser Line Perforationstechnologie MLL-1 generiert einen nicht geradlinigen Lochreihenanordnung auf den Produkten. Z.B. sind auf Mundstückbelagpapierblättchen der Zigarettenfilter, RYO usw. jetzt losgelöst von den seit 20 Jahren traditionell koaxial verlaufenden Laserperforationen, wellenförmige, Zickzack, Rechteck, Dreieck, gewundene Lochreihenlinien oder Paare, Firmenlogos, Kryptogramme, anti-counterfeiting Merkmale oder andere Perforationsausführungsformen mit zeitlich sehr schnell und präzise aus gelenkten Laserstrahlen möglich. Alles dies bei Lochgrößen von 60 - 120 µm, Lochdichten von typisch 10 – 30 Mikrolöcher pro cm in einer jeder Lochreihe, Lochsequenzen von 100.000 bis 300.000 Löcher pro Sekunde bei Porositätsbereichen von 100 – 800 C.U.

Verfahrens-, Vorrichtung und Produktschutzanmeldung DE102004012081.

Verpackungs- und Kunststofffolienprodukte verschiedenster Art lassen sich mit dem neuen Mikro Laserperforationsverfahren MLL-1 in gleicher Weise veredeln oder behandeln.

Wobei sich die Anwendungen nicht nur auf das Perforieren beschränken, sondern auch für den Einsatz der gigantischen Industriebereiche zur Lasermaterialbearbeitung und Oberflächenbehandlungen wie schweißen, formen, trennen, vergüten, bohren, öffnen, fügen usw. übertragbar sind.

Ventilation von Massenprodukten
Die elektrostatische Mikroperforation ist seit 30 Jahren zur Ventilation von wenigen Nichtfilter- und jetzt für fast alle im Markt befindlichen Filterzigaretten eingesetzt, um gesteuerte Luft Bypass Eigenschaften, dem so genannten Lindströmprinzip, zu erzeugen. Hierzu wird das Zigarettenpapier für wenige Nichtfilterzigaretten z.B. auch Roll-your-own RYO und bei fast allen Filterzigaretten das Mundstückbelagpapier, dem so genannten Tipping aber auch das Plug-Wrap Papierblättchen, elektrostatisch im Offline Verfahren Zonen Mikro perforiert, um gewünschte Poren im Durchmesserbereich von 10 - 70 µm generieren.

Oder mit fokussierten Laserstrahlen in Offline Verfahren Lochreichenperforationen aber auch im Online Verfahren an der Filteransetzmaschine direkt durch das Mundstückbelagpapierblättchen bis in den Zigarettenfilter gewünschte Poren im Durchmesserbereich von 60 - 120 µm einzubringen, um so Nikotin-, Kondensat- und Schadstoffanteile für den Raucher über die gesteuerte Ventilationskombination auf strikt vorgegebene Werte zu reduzieren.

Vor vielen Jahren hat IPM u.a. auch zur Online Mikroperforation an Zigarettenherstellungsmaschinen ein Verfahren entwickelt und seinerzeit unter EP0460369 sowie DE4018209 zum Patent angemeldet, welche das Einbringen von Mikroperforationsprofilen über die jeweilige Zigarettenlänge sowie in deren Umfang an beliebigen Stellen des Zigarettenpapiers erlaubt.

Optische online Permeabilitäts- oder Porositätsmessung
Da die naturporösen oder zu perforierenden Bahnmaterialien sich mit Bahngeschwindigkeiten bis zu 600 m/min und in Bahnbreiten bis zu 2000 mm bewegen, gestaltet sich eine pneumatische, also bahn berührende Porositätsmessung, exorbitant schwierig. Hinzukommend sind diese Messmethoden mit Nachteilen der Bahnzugserhöhung, des Materialabriebs, Faltenbildung, Undichtigkeit im Messkopfbereich, starken Verschmutzungen, Nichtlinearitäten und Schwierigkeiten stets verbunden.

Daher bieten sich optische Messverfahren zur Transmissionsmessung als Funktion der pneumatisch, statischen Gasdurchlässigkeit für naturporöse oder Nano, Mikro bzw. Makro perforierte Bahnen an. Dabei sind die gestellten Anforderungen aufgrund der eingangs genannten Produktverarbeitung und online Kontrolle, extrem kleinen geometrischen Porenabmessungen, relativ hohen Bahngeschwindigkeiten und guter Messwertreproduktion mit der optischen Porositätsmesstechnik in idealer Weise zu lösen.

Zukunftsperspektiven

Die elektrostatische ESP Nano- oder Mikroperforation findet vorzugsweise ihre Anwendung in Bereichen der Veredelung von Feinpapieren, Verpackungsbahnen, Vliesstoffen, Non-Woven, Filter-, Sack- oder Kraft- sowie Spezialpapiere verschiedenster Art, insbesondere bei der zusätzlichen Behandlung von Bahnmaterialien zur Erzielung besonderer Eigenschaften, welche aus physikalischen oder prozesstechnischen Gründen NICHT mit anderen Verfahrenstechniken erreichbar sind.

Die state-of-the-art, industrietaugliche und im Dreischichtbetrieb zuverlässig arbeitende ESP Perforationstechnik, deren Integrationsmöglichkeit in vorhandene Umroller- oder sonstige Bahnlaufanlagen sowie auch als völlig eigenständig arbeitende Perforationsmaschinen möglich sind, wird zukünftig neue Anwendungsbereiche erschließen und Produkte mit besonderen Eigenschaften entstehen lassen.

Ventilation of mass products

Electrostatic perforation has been used since 30 years for ventilation of non filter, RYO or filter cigarettes to create a directed and guided air bypass or Lindstroem principle. For this purpose, cigarette paper for some non filter or RYO cigarettes and almost every kind of filter cigarettes tipping papers are perforated electro statically OFFLINE in zones from 2.0 – 6.0 mm width or in rows with ONLINE or OFFLINE by use of slow, fast flow, sealed-off or SLAB CO2 gas or diode laser in order to reduce the harmful substances such as nicotine and condensate down to allowed values. Another effect is the possibility to control the degree of ventilation of Cigarettes.

Online micro perforation – porosity profile

Many years ago IPM had developed a multiple online electrostatic micro perforation OESP-1 units at cigarette making machines which was patent applied with EP0460369 and DE4018209.

http://www.freepatentsonline.com/EP0460369.html

The method and the device for electro-erosive perforation of cigarette paper basically operates with at least two pairs of electrodes which are ignited at the same time in such a manner that each perforation section is treated twice in order to provide a corresponding intensity of perforation, taking into consideration the duration of ignition and the web speed. In particular, the invention operates with at least four pairs of electrodes (I to IV), between which the web (10) of cigarette paper to be perforated is moved through. The cigarette paper is moved in the longitudinal direction of the cigarette to be produced later, the width corresponding to the circumference of the cigarette plus an overlap section for bonding. Perforating is carried out transversely to the direction of movement, that is to say an accurately defined zone section is produced around the circumference of the cigarette. The pairs of electrodes are arranged at a distance which corresponds to half the cigarette length (a, b, c) when four pairs of electrodes are used. The first and the third pair of electrodes are ignited simultaneously. A distance-dependent control causes the second and fourth pair of electrodes also to be ignited simultaneously when the previously perforated sections have traveled the distance of half a cigarette length. Each section is perforated four times, the speed at which the web (10) can be moved being determined not by the spacing (half a cigarette length) of the pairs of electrodes but by the spacing of the pairs of electrodes in each case simultaneously ignited (one cigarette length). This provides for uniform, intensive and very powerful perforation and the cigarette paper treated can be continuously supplied to the cigarette machine for further processing in the longitudinal direction of the cigarette.

That electrostatic micro perforation process enables cigarette or tipping paper while cigarette making processes to reduce nicotine and condensate levels for non-filter and filter cigarettes as well. The OESP-1 devices opens fully new possibilities for cigarette or tipping paper ventilation during cigarette manufacturing by entire perforation cassettes integration into cigarette making machines as Max-S, Protos 80, Protos 90, Mark-9 etc.

Advantages during manufacturing

Compact all-over-dimensions, direct mechanical integration of perforation units, easy functional interfacing and full EMI acceptance in order of EN or NEC standards archiving high production efficiencies with controllable ventilation grades on highly automated cigarette making machines.

Patented, powerful, dual high frequency switching electronics and multiple perforation performances of the circumference of each cigarette enables problem less perforation on high-speed cigarette making machines up to 12.000 cpm

Porosity ranges from 50 up up to 400 C.U.
pore densities from 25 up to 300 pores/cm2
hole size from 30 up to 80 micron

Product properties with micro 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, MOSFETS, 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 grant DE10328937 for power electronics.

Online porovision control

Since naturally porous web materials or web materials to be perforated are processed with speeds of up to 600 m/min by web widths of up to 2000 mm are used, pneumatic porosity control, hence measuring whilst touching the web are highly difficult. Further difficulties of pneumatic measurements are the disadvantages of rising of web tension, material abrasion, folding, leakage at measuring head, impurities, non linear processing, calibration problems and scanning effects.

Thus, optical measuring offers better ways for transmission measuring the pneumatic static permeability for naturally porous or nano, micro or macro perforated webs. The conditions mentioned above can be easily met by using the optical porosity or porovision control technology thanks to the mentioned product processing and online control, extremely small pore dimensions, relatively high track speeds and a good value repetition. That full independent from principle material facts as consistence, thickness, weight, coloring, formation, smoothness, brightness, opacity, and other influences. Patent pending for process and device DE10251610 - China patent grant 200310104764.

Therefore, IPM – International Perforation Management – has developed a pending, stationary and transverse optical porovision control processes and systems which working with multiple color and wave length sensors, a precision line laser, scanning speeds from 20 – 200 mm per second, porosity ranges from 80 up to 3000 C.U., perforation lines detection by 0.1 mm, nano micro holes sizes from 500 nm up to 200 µm diameter and up to 250 holes/cm2.

Optical online OPSS-1 porosity, permeability scanning systems for substrates

Patent pending DE10251610 – China patent grant 200310104764

Introduction

A German-Thai high-tech, engineering company has developed an optical online porosity or permeability scanning system. It works with two different multiple sensors units, i.e. precise line laser, colour sensors and internal controller unit for real-time positioning and porosity control in light transmission mode whilst scanning across the fast running webs up to 600 m/min.

The main advantage compared to existing technologies is the measurement of perforation zone/line positions and porosity levels in the same time while the scanner system across the running material web up to 2000 mm width.

Science, R&D, Universities, industrial partners for a licence agreement and / or technical co-operation are sought.

Working principle

The porosity control of natural porous and/or perforated web material in laser or electrostatic perforation systems which are produced in speed ranges up to 600 m/min and web widths up to 2000 mm is difficult to measure with pneumatic systems because of following disadvantages: web tangency, web toughing, material flaking, formation of folds, dust and dirt entering the system.

These difficulties can be overcome with stationary or scan, optical porosity measurement systems for porosity ranges from 80 up to 5,000 Coresta units (ml/2cm2/min) respectively 3 to 50 l/m2/Sec. (Franksystem) by nano, micro or macro holes sizes from 0.5 up to 500 microns and hole densities from 10 macro holes per cm up to 400 holes per cm2

The optical online porosity control technology is designed to scan perforation zones with a multiple sensor and their positions with a precision line laser to determine all data in real time with an internal controller unit. It controls roll material or bobbin formats, either as a stand-alone unit or mechanically coupled with existing scanning units which measure the material weight, thickness, opacity, density, brightness, smoothness, formation, etc.

By laser and electrostatic perforation in bobbins and wide paper web formats optical online control processes and their devices are indicated with transverse movements across the web and simultaneously collections of perforation positions and porosities by two different sensor systems.

Both measuring systems move transversely between 50 up 400 mm/Second over the fully web width. They consist of a line laser detect the quality and position of single holes, groups of holes or defined perforation zones into the measuring gap of 5.0 mm. At the same time, the multiple light transmission sensors monitor all porosity profiles and determines envelope curve and calculate the integrals.

Applications and Advantages

Thus direct feedback into the perforation system makes it possible to compensate any changes in terms of porosity and perforation locations so that each jumbo production roll up to 25,000.00 meters as well single or quadruple bobbin sets can be produced and controlled without intermediate stops and certificated in quantity und quality on their end.

Natural porous or perforated web material as cigarette, tipping, plug-wrap, filter, packaging, non-woven, flees, coated paper as well micro or macro perforated plastic films as BOPP, LDPE, PP, EVA, HDPE, etc. are controllable with the OPSS-1 scanning system.
