Еucalyptus pulp as alternative raw material in paper production
Keywords:
pulp and paper industry, hardwood cellulose, cellulose pine, eucalyptus pulp, consumer properties of paper for products sanitary purposesAbstract
Background. Using eucalyptus pulp in paper products for sanitary purposes is due to several advantages including low cost and availability of the properties required for high quality products.
The aim of the article is to study the properties and selection of alternative fiber semi-finished products, including eucalyptus pulp in paper products for sanitary purposes.
Material and methods. Sulfuric bleached eucalyptus pulp produced by BOTNIA (Finland) was chosen for the study as an alternative raw material. Sulfuric bleached hardwood pulp produced by GIC Arkhangelsk (Russia) was chosen for comparison. Paper samples which differ among themselves in hardwood pulp faction (table 1) were produced for research.
Moisture proof resin Kymene 25 X Gel was put into paper pulp to reduce "failure fibers" over the net of paper machine with an increase in the share of short fiber composition of eucalyptus pulp.
Research of consumer properties of paper was made by standard methods [5–10].
Results. The influence of eucalyptus pulp on consumer properties of paper products for sanitary purposes has been identified. It has been established that the content of 30 % eucalyptus pulp in pulp composition significantly improves consumer properties such as mechanical strength of paper, absorbing ability, softness, friability and moisture proof. The use of eucalyptus pulp in paper composition causes lower costs of chemicals used in the manufacture of paper.
Conclusion. Efficiency and expediency of eucalyptus pulp in the composition of pulp products for products for sanitary purposes has been proven. The obtained paper meets the regulatory requirements regarding quality.
