The corona adopt high frequency and high voltage power to occur corona between discharge electrode and corona roll,forming low
temperature plasma, through the interpolar air ionization and produce ozone.The ozone is a strong oxidizing agent,it can changes the
molecular structure of the plastic surface to turn nonpolar into polar,at the same time ,corona can make the material surface appear
micro uneven cavity and make its surface coarsening,enhance the surface activity ,so that the surface tension is improved,the ink and
glue etc can permeate into the processed materials further,so as to achieve the ideal printing and sizing effect .
Corona processor is mainly used in the surface treatment before printing of the the nonconductive material,it can used with film
blowing machine,splitting machine ,printing machine etc ,enhance the surface tension of the materials,which can help ink and glue
permeation,increase the affinity materials and obtain the good effect.
The roller of the discharge frame which equipped to the corona processor is silicon roller ,the diameter is 46~75mm generally,which
can customize different treatment width for special requirement.
The discharge frame is important parts of the corona processor,it is made up of frame,silicon roller,electrode knife, idle roller etc.
1.With shelf-resetting electrode knife.two rolls cohesion without stop working.
2.The single or double processing and treatment width etc. parameters can be customized according to the customer requirements.
3.Imported silicon roller and discharge frame proprietary material,enhance impact density.
4.Applicable models:printing machine,film blowing machine,sealing-tape machine,Laminating machine,casting machine.
5.Applicable material:woven bag printing,laminating etc.
