A simulation model for pulp bleaching has been created. The model will yield information of phenomena taking place during pulp bleaching, especially about reactions between lignin and bleaching ...

The pulp and paper industry is full of difficult processes and aggressive matrices. Continuous monitoring of quality and analyzes must be carried out to run every phase of the papermaking process ...

Billerud, a Swedish company with four integrated pulp and paper mills, serves specific packaging-market segments. In 2000, the process-engineering department at Billerud's mill in Skärblacka sought to ...

Bleaching gels activated by Diode lasers in Power Bleaching act as effective insulators, helping prevent large increases in temperatures within the pulp chamber. Teeth should never be directly ...

Bleaching gels act as effective insulators helping prevent large increases in pulpal temperatures. Most of the bleaching lamps tested did not raise the pulpal temperature to dangerous levels. Care ...
