Description
Technical field
This utility model relates to membrane production equipment field, a kind of produces for bidirectional stretching polypropylene film
Corona treatment.
Background technology
In film production, most of plastic sheetings (such as poly-hydrocarbon thin film) belong to non-polar polymer, especially biaxial tension
Polypropylene film surface tension is relatively low, typically at 29-30mN/m, theoretically, if the surface tension of object is less than 33mN/
M, the ink being currently known and binding agent all cannot be at adhesion-tights above, it is therefore desirable to provide bidirectional stretching polypropylene film
Surface tension.
Utility model content
The purpose of this utility model is to provide a kind of corona treatment produced for bidirectional stretching polypropylene film, with
The problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of for bidirectional stretching polypropylene film produce corona treatment, it include drive roller, described driving roller sets
Being equipped with drive shaft, described drive shaft is connected with external driving motor, and described driving roller is metallic roll, arranges outside described driving roller
Having insulating barrier, on described driving roller, volume has polypropylene film, described driving roller to be provided above electrode, and described electrode is along driving roller
Axis direction be arranged in parallel, is filled with metal charge in described electrode, forms air gap between described electrode and driving roller, described
Electrode is connected with supply unit by wire, is provided with transformator in described supply unit, and described driving roller is provided with earth lead.
As the further technical scheme of this utility model, described electrode is strip earthenware.
As this utility model further technical scheme, described metal charge is aluminum alloy granule implant.
As this utility model further technical scheme, described electrode lower end is provided with cambered surface.
Compared with prior art, the novel offer of this practicality is a kind of at the corona that bidirectional stretching polypropylene film produces
Reason machine, novel structure, electrode utilize altofrequency high voltage to produce low in processed polypropylene film surface corona
Isothermal plasma, makes polypropylene film surface produce radical reaction and make polymer crosslink, and surface is roughening and increases
Its wettability to polar solvent, these gas ions, by shocking by electricity and penetrating into by its molecular structure of surface breakdown of print body, are entered
And by processed surface molecular oxidation and polarization, ion electric shock erosion surface, so that increasing the adhesive ability on stock surface,
Cambered surface adds the work area of electrode, is received sided corona treatment by driving roller strap to move polypropylene film uniform motion.
