Corona device and plasma devices are environmentally friendly electrical devices used for surface preparation processes.<\/p>\n

With this method, surface properties are improved without using any chemicals and without changing the main properties of the material, thus increasing the adhesion, painting, adhesion and antiseptic properties of the treated material.<\/p>\n\t\t<\/div>\n\t\t\n\t\t

The most important effect of corona treatment is to change the surface properties of the plastic or film material.<\/p>\n

In particular, it is to increase the surface energy of the material to be processed, measured in dyne\/cm. Corona systems make this change by applying high voltage to a specific material surface for a certain period of time.<\/p>\n\t\t<\/div>\n\t\t<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>

Another way to measure the properties of materials such as printing, bonding and lamination is to control the contact angle of the materials. The contact angle is established on the line defining the adhesion surface between a liquid droplet and a solid.<\/p>\n\t\t<\/div>\n\t\t<\/div><\/div><\/div>

Full wettability is achieved when the contact angle approaches 0\u00b0 and the liquid completely \u201cspreads\u201d.<\/p>\n

Poor wettability is achieved when the contact angle approaches 180\u00b0 and liquid forms.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\t\t\t
