Fine Paper Grades
|
Banknote- and security paper Steam application such as the VIB SteamTech on these grades is used for raising output. VIB MoistureTech and VIB CurlTech systems can be used for better flatness and improved surface quality. Spray systems such as the VIB AirTech are used downstream of a size press for moisture control and for curl control. High zone definition is most important especially for watermark grades, as the watermark area must be controlled separately for good results. For these grades steam can be applied in the press section with steam showers such as the VIB SteamTech for moisture profile correction and for higher output. A production increase of 6-8% is quite likely. Curl control can be achieved with a VIB CurlTech or spray system such as VIB AirTech Plus 6. |
Wood free printing and writing grades SteamTech steam showers are most efficient to increase dryness. Production increases of up to 10% can be achieved; the moisture profile can be exactly controlled by adding different amounts of steam per control zone to the sheet. The use of high-resolution steam showers with control zone width of 50 mm results in 2 sigma values of less than 0.1 on specific applications. VIB SmoothTech steam showers can improve smoothness and gloss of the surface of calendered grades. Improvements of up to 50% and more can be achieved.
As the leading company for moisture and steam applications, VIB Systems has solutions to many different moisture problems throughout the fine paper industry worldwide. Page |
