Predicting compressive yield strength of fl uting medium


Automated tests that determine the quality of fl uti ng medium have been developed by a group of producers. PPL reports


medium in corrugated packaging material has been launched by ABB. The L&W S-Tester widens ABB’s range laboratory quality measurement systems to help paper producers improve quality and reduce costs. The S-test method was


A


developed by a group of fl uti ng producers (CCB-CEPI) to provide


new, quick test method for determining the quality of fl uti ng


a more reliable and easy measurement method than the ti me-consuming fl at crush of corrugati ng medium CMT test (Concora Medium Test). This test method can be fully automated. It is said to correlate well with


the compressive yield strength potenti al of fl uti ng medium in a CMT test. This yield strength is more relevant than standard CMT when predicti ng the ability of fl uti ng medium to keep the liners apart, without losing its own


strength in a corrugated board constructi on. ABB says the L&W S-Tester will provide quick and accurate feedback; it can also perform automated S-tests in L&W Autoline (a complete paper quality measuring system) that will enable mills producing fl uti ng-medium to saving producti on costs. These measurements will help to reduce energy consumpti on through the eliminati on of over-refi ning, opti mise the use of starch


additi ves, and improve overall quality by generati ng a uniform paper product. “This test method, developed


by a group of industry partners, is now off ered as a fully-supported product only by ABB,” says Thomas Fürst, global product manager, ABB Pulp & Paper products. More informati on from ABB AB/Lorentzen & Wett re. Tel: 46 8 477 90 00. Email: gunvor.latva@ se.abb.com
