CORONA TREATER

Corona treatment is a very effective way to increase the surface tension of various materials. By treating the material with high frequency and high voltage corona discharge, the surface of a substrate is given with adhesive properties so that it becomes more impressible to inks, coatings and adhesives.
Corona treatment, is known as dielectric barrier discharge (DBD), mainly used for surface treatment of plastic films and sheets. Before a substrate to be processed with ink printing, laminating, blown film / cast film extrusion, coating, gluing, modification and polymerization, corona treatment should be applied to increase the bonding characteristics of the substrate (increasing the dyne level).

PLASMA TREATER

Plasma is often referred to as the forth state of matter. It is based on the physical principle that by adding energy to matter so that solid becomes liquid, and the liquid becomes gaseous. If we continue to supply enough energy to the gas, the gas molecules will be ionized and generates the plasma. Atmospheric plasma and vacuum plasma are the two primary categories. The atmospheric air plasma treater utilizes blown ion or blown arc plasma technologies.
Functions of plasma surface treatment
1. Surface cleaning: removal of dust or other contaminants, as well as elimination of static electricity;
2.Surface activation: improving the wettability of surfaces;
3.Surface coating: enabling the functionalization of the substrate surfaces;
4.Increasing the penetration and improving bonding strength;
5.Improving long-term durability and reliability of the bonding;
5.Assuring the hydrophilicity;

WEB CLEANER

Web cleaner features contact cleaning rolls that are formed by the reaction of silicone rubber and PU key raw materials, capable of removing dust particles with size less than 2 μm. During contact web cleaning, the contact cleaning rolls come in physical contact with the product surface to collect contaminates like hair, scurf and debris, and transfer them to adhesive rolls. Various configurations of high, medium and low adhesive level are available based on actual applications needs.
Applications:
1. Suitable for coating machine, printing machine, clean room, etc.
2.Web dust removal and surface cleaning for various films, adhesives, paper, foils, laminates, non-woven, medical packaging, etc.
