Description

15 451 205 För mätning av det framställda materialets absorption användes en absorptionstest med metylenblått.
En viss mängd av materialet skakades i en lösning av metylenblått, materialet avfiltrerades och lösningens färgintensitet mättes i en spektrofotometer.
Vid försök för framställning av cellulosafibrer belagda med aktivt kol användes olika massatyper, nämligen oblekt tallsulfatmassa, blekt tallsulfatmassa, blekt björksulfatmassa och kemimekanisk massa, s k CTMP.
Ur de olika massatyperna framställdes en suspension med en koncentration av 3 g/l. Den önskade kolmängden tillsattes 1 liter av ifrågavarande suspension. Massasuspensionen tillsattes en katjonaktiv tensid i en mängd av 0,02 ml/g massa. Efter noggrann omrörning så att allt kol verkligen blivit vått, arkades blandningen i en arkform. Efter arkningen pressades arken och torkades på torktrumma vid 60 ° C i 2 timmar. De erhållna resultaten framgår av nedanstående tabell.
