What is Plasma ?
“PLASMA“ is a gas, which
contains a big amount of electrical charges. In constast to normal gases,it is
conductive although it appears electrically neutral to the outside.
Ionisation of gas molecules for (nobel gases electrons from the molecules and
atoms. Besides electrons, ions and normal neutral molecule fragments
(radicals),which are chemically high reactive due to their unstable structure.
This reactivity is used in many technical pretreatment before printing and
gluing by oxidation of the surface of the ambient conditions using air as
working excitation are used for this application
eltech`s Plasma surface
treatment technology offers innovative solutions to adhesion and wetting
problems in many industries. Component preparation is an important step prior to
bonding, painting, varnishing and coating processes.
The purpose of surface treatment of polymer-based materials is to increase
surface wettability through electrical discharge. The low surface energy of
polymerbased substrates often leads to poor adhesion of inks, glues and
coatings.
Plasma treatment provides an economical solution for the cleaning and activation
of component surfaces before further processing. Plasma surface treatment
improves wettability and adhesion of ink, glues and coatings on many
different surfaces.
Plasma surface treatment provides an economical solution for the cleaning and
activation of complex surfaces before further processing.
Plasma treatment system is highly effective at treating and cleaning
all types of polymers, elastomers, glass and even conductive surfaces. It treats
extruded, pultruded, molded and formed materials. Treatment is ideal for PE, PP,
PET, nylon, vinyl, polystyrene, polycarbonate, PVC and all other types of
thermoformed and thermoset plastics.
Eltech plasma treatment
improves folding carton bond strength.
