To reduce the production costs of diapers, sanitary napkins and adult diapers. With the Atmospheric Plasma Device, glue consumption will be reduced by 40% to 50% and super absorbent polymer consumption by 30% to 40% in these production processes. In these processes, glue and SAP (super absorbent polymer) are supplied from abroad and constitute approximately 40% of the product costs. For this reason, the use of Atmospheric Plasma Device in such machines becomes a necessity in terms of economic as well as foreign competition. Expanding the product range of our company with this project to be developed, expanding our national and international market share by offering the product to the domestic and international market and preventing the current account deficit in the sector as much as possible are among the reasons for the initiation of our project.
Secondly, it is aimed at many companies operating in the packaging industry, automotive, electronics, aviation and health sectors. When plasma energy comes into contact with solid materials such as plastics and metals, it interacts with the surfaces and changes important surface properties such as surface energy. This principle is used in the manufacturing industry for selective modification of material properties. Pre-treatment with atmospheric plasma energy enables the adhesion and wettability of surfaces to be significantly and precisely adjusted. Thus, completely new materials (including apolar ones), environmentally friendly, solvent-free (VOC-free) paints and adhesives can be used in industry.
Many chemical pretreatment methods can now be replaced by atmospheric plasma treatment. Thanks to the high energy level of the plasma, the structures of chemical or organic substances on the surface of the material can be selectively broken. Plasma energy is more favourable than any other form of energy for the accurate surface treatment of the most diverse materials. Even the most sensitive surfaces can be safely cleaned, activated and coated. In this way, plasma can be integrated directly into the production line. Thanks to its wide range of applications, atmospheric plasma has become a key technology for innovative surface treatment solutions.
Polypropylene (PP) accounts for approximately 35% of the 13 different polymer materials used in the automotive and aircraft industries due to its light weight, easy processability, high thermochemical resistance, recyclability and economy. Despite its advantages in industrial use, low adhesion problems are experienced in applications such as coating, painting and bonding due to its 95-109° wetting angle and 28 dyne/cm2 surface energy. It is possible to prevent these problems with some surface modification processes and many methods have been developed for this purpose. The main surface treatments are mechanical etching, chemical etching, flame activation, corona activation and a new method, atmospheric pressure plasma surface activation.
In recent years, atmospheric pressure plasma, which is one of the types of plasma that is not in thermodynamic equilibrium (cold), has been a method that has been researched and developed in improving the surface properties of polymer materials with low surface energy and increasing surface polarity. With atmospheric pressure plasma surface activation processes, it is possible to increase the surface energy of PP material with a surface energy of 28 dyne / cm2 above 72 dyne / cm2. In activation process applications, the gas to be used as a plasma source is ionised in the system and creates a plasma flame.
