YANKEE DRYER CYLINDER COATING & INNOVATIVE TRIPARTITE COATING CONCEPT
The Yankee Cylinder is one of the most integral parts of the tissue paper machine. Its complete protection and stable runnability guarantee the production of excellent quality tissue paper products.
We, in GIG Chemie, fully recognize the industry’s essential requirements; thus, we revolutionized our approach by offering the latest & advanced adapted chemistries with our in-depth knowledge and experience in streamlining Yankee coating properties.
Our innovative tripartite coating concept is explicitly designed for the inhibition of corrosion and passivation of the Yankee dryer cylinder. These products yield to the production of soft and bulky tissue having a uniform smooth surface.
INNOVATIVE TRIPARTITE COATING CONCEPT
GIG Chemie’s innovative tripartite coating approach is based on a three or four-component Yankee coating system. It contains first-rate protective additives, which are necessary for the excellent protection of metal surfaces combined with crosslinking & non-crosslinking adhesives coating agents that are sprayed together onto the Yankee cylinder to acquire the desired results. This latest technology enables us to satisfy all requirements of most tissue machines, including the latest high-speed tissue machine with an operating speed of 2000 m/min and visconip press technology.
Our Releasing Additive, which is used together with the base coating & adhesive, is a non-ionic creping aid and has been developed for controlling the release effect on the Yankee cylinder while keeping the cylinder surface cleaner than usual.
Depending on your process requirements, our Release Agents are available in grades ranging from resilient to soft release effect.
Our well-experienced technical service team will guide you in selecting the most appropriate product combination for your specific process and machine requirements.
While using our innovative tripartite coating concept, you can improve and sustain your productivity and achieve the following key benefits:
- Unsurpassed surface protection of the Yankee dryer cylinder
- Extended blade life
- Improved sheet adhesion, which provides a fine Crepe with excellent softness
- Increased bulk of lower gsm tissue, e.g., facial, pocket tissue
- Improved moisture profile
- Stability of the sheet in terms of ´´floating´´ after changing the doctor blade
- Stability of thickness, creping and softness after changing the doctor blade
Deposits usually occur on the Yankee edges which are not covered by the paper, causing severe problems such as;
- excessive blade wear and blade vibrations
- chatter marks
- an increased grinding interval of cylinder
- irregular adhesion
- Varying paper quality
GIG Chemie offers Edge Coating Agent, which contains corrosion inhibitors that forms a protective film on the Yankee edges, thereby providing the cylinder edge with an incomparable cleaning effect.
