Evaluation of paper permanence

Summary The thermal stability of papermaking pulps under conditions of accelerated aging and at pyrolytic temperatures was examined. Degradation was found to be extremely complex and influenced by both the technical processes of papermaking and by the experimental methods used. At moderate temperatures, as used for accelerated aging, the folding endurance test was found to be a sensitive measure of degradation. Methods of reducing the variability of the test were considered, and a new technique capable of handling widely different results was developed and evaluated.Several papermaking pulps were artificially aged and the resultant loss of strength attributed to the interaction between a gradual fiber strength reduction and a rapid increase in interfiber bonding. Excessive initial inter-fiber bonding decreased handsheet stability. Softwood sulfite and kraft pulps were more stable than a birch kraft pulp, but the behavior of sulfite pulps varied greatly. The presence of lignin or a high hemicellulose content was not of itself sufficient to cause rapid aging.The pyrolytic behavior of pulps was investigated using thermogravimetric analysis. Papermaking pulps had mean pyrolytic activation energies between 30–45 kcal/mole. The activation energy decreased as the reaction proceeded. Correlation of these activation energies with the rate of loss of physical properties during accelerated aging was not good. The results indicated that the rate determining reactions for pyrolysis and for low temperature degradation are different but that the pyrolytic behavior is partially determined by the supramolecular structure. Empirical stability indices, based on both the integral and differential thermograms, were calculated, and these correlated well with the relative rates of loss of physical properties.A large part of this paper is based on the thesis of R. D. Carwell. Contributions were also made by L. Lyon and M. C. Varshney. This work was partially funded by the National Bureau of Standards     

Biotechnology in the pulp and paper industry

Summary Biotechnology implies the technical exploitation of biological processes. One of nature's most important biological processes is the degradation of wood and other lignocellulosic materials to carbon dioxide, water, and humic substances. Consequently, there should be possibilities to apply biotechnology to wood conversion. This article summarizes briefly the knowledge relating to the enzymic degradation of cellulose, hemicelluloses, and lignin. However, it is mainly focused upon biotechnological processes in commercial use or in various stages of development for the pulp and paper industry. Areas covered are ethanol and protein production, water purification, development of new bleaching techniques, microbial delignification (biopulping), and development of biosensors for analysis of pulp fiber surfaces.Academy lecture presented on May 18, 1989 at the Fourth International Conference on Biotechnology in the Pulp and Paper Industry.

Two-dimensional linear viscoelasticity of paper

Summary Linear viscoelastic properties of laboratory handsheets have been investigated from the two dimensional aspect. According to the linear theory of viscoelasticity, the behavior of transverse isotropic materials such as handsheets subjected to plane stresses is fully described by the two in-plane relaxation functions G₁₁ (t) and G₁₂ (t). In the present paper, some viscoelastic characteristic functions describing responses to in-plane deformation histories are derived from G₁₁ (t) and G₁₂ (t) determined by strip biaxial stress relaxation testing. The predicted uniaxial relaxation function curve was in good agreement with the experimental one, and the viscoelastic Poisson's ratios in uniaxial stress relaxation and in uniaxial constant strain rate extension were decrease functions of time. Effects of beating on the areal dilatation and shear relaxation functions are discussed by introducing the classical concept of relaxation spectrum.     

Optimal rate of paper recycling

This paper uses a dynamic land allocation model combined with the infinite rotation problem to determine theoretically, the recycling rate that maximizes the forest area and, thus, the number of trees under social management thereby integrating both positive externalities generated by the forest and social costs of not recycling. The results suggest that, when the recycling rate is low, increasing it to its optimal level will result in more land area being devoted to forestry and, thus, more trees. However, increasing it beyond its optimal level will reduce the number of trees in the long run. In addition, the recycling rate that maximizes the forest area is optimal in the sense that it also maximizes the social net benefit. An application shows that increasing the recycling rate up to its optimal level considerably increases the forest area. The increase in the social net benefit is very small.
