Mikrobielle Werkstoffzerstörung – Schadensfälle und Gegenmaßnahmen für Kunst- und Naturstoffe: Papier und Füllstoffe

Microbial deterioration of materials – case histories and countermeasures for plastics and natural materials: Paper and additives During the production of paper and cardboard several aspects of microbiological attack may be observed. Paper raw materials, additives and the end product paper itself are attacked by microorganisms. The results are deterioriation and an alteration of the properties of valuable raw materials and a reduction of the paper quality. The greatest important economic loss arises from slime formation in the fiber preparation systems and in the paper machine itself. Biofilms are the reason for break-downs in production and affect the quality of the product. This article describes the sites where trouble during production occurs, the effects and value of the loss based on microbiological growth. Chemical and technical arrangements to reduce the origin of damages are discussed.
