In-situ dyne surface tension wettability control
Method and device for optical inline tough less surface tension
control ODSTM-1 in DE19543289 by which the fast moving substrate
through the measuring gap. It’s transmitted with a chromatic beam and
spectral selected light source were two optical channels are displaced
and polarized by 90 degree to each other.

Both optical axles are precise and motor driven shift able in certain
angles from 25-65 degree. The spectral light photons, transmission,
extinction, absorption grades are detectable by two optical CCD
imagine vision devices, integrated into the sensor case on other side
of the substrate.

Material condition
At high-speed moving substrates means plastic foil, flexible, hi-tech,
film, laminate, coating, bonding, labeling, co-extrusion, BOPP, LDPE,
LLDPE, HDPE, MDPE, MAS, MOH, MEV, PET, FEP, PP, PE, PS, PO, EVA, PTFE,
PVC, PTFE, Vinyl, Polyester, wrapping, self-adhesive tape, high
strength, cross laminated, adhesive coated films, reflective or
magnetic sheeting, automotive tape products, inkjet, heat sealing,
security, pressure sensitive tapes for entertainment or building
industry.

Masking or printable plastic films, polycarbonate, acrylic, extruded
or polished cellulose, optical grade polycarbonate, sheets for IR or
laser protection, filter sheet, imaging, capacitors, bi-oriented
polystyrene sheet, multilayer co-extruded film, PVC, PETG, polyimide,
tear tapes for aerospace, inner covering in aircrafts, automotive,
medical, bioengineering, renewable, agriculture, marine, household,
commercial, domestic, construction, high-porous membranes for uses in
alkaline lithium ion batteries, fuel cells, filtration equipment.

By gauges 10-500 microns, fabric widths up to 10,000mm and web speeds
up to 18 m/s.

Optical properties and quality control
Material specific wavelength selection 1,200-1,800nm, material
specific finger prints, molecular spectral properties, transmission,
optical angle scanning, ultra low level stray scatter light detection,
polarization, slot diaphragms, transverse displacements control the
light beams along and far from the optical X and Y axes.

The results are extreme scattering, diffraction, NIR, IR, stray light
photons generation into the layer areas at both sides of the moving
substrate.

Their reflected and transmitted light intensities enables the
determination by defined formulas and data matrixes the surface
tension values in ranges from 28-62mN/m or dynes which are direct
associate and bond to real static values for statistical quality
control (SQC).

And this entirely independent of the material specific influences as
like surface consistency, thickness, density, weight, opacity,
coherence, filling, stretching, shrinkage, structure, co-extrusion,
polar grouping, temperature, intrinsic motivation or viscosity,
hydrophobia, hydrophilic molecules, hydrogen, moisture, water steam
proof, bi-layer, polymer, patterning, nanostructure, irradiation,
isotopic, catalyst, coherence, absorption, photo mask effect,
radiation, resonance bands, Raman, electron spectroscopy for chemical
analysis ASTM or ATR method, property, acoustic photonic liquid
effects, pre material treatment as corona, plasma jet, flam
treatment.
