mechanical pulp

Ingredients

mechanical pulp

Preparation Steps

Original Recipe Text

The material is a mechanical pulp sheet, represented by samples MC (Control/Before ageing) and MA (Aged/After ageing). The study utilizes infrared spectroscopy to determine how mechanical pulping processes affect the long-term chemical stability of the paper sheet (p. 23).

Evidence

"Infrared spectroscopy of mechanical pulp sheet"

Remarks

Infrared spectroscopy (Fig. 6, p. 23) was used to compare the mechanical pulp sheet before and after ageing. The spectra show transmittance levels for O-H, C-H, and CH2 functional groups. A notable peak is observed at 894 cm-1. The data suggests changes in the relative intensity of these bands post-ageing, reflecting the chemical degradation of the mechanical pulp components.
