ECOLOGIC AND SAFE TISSUE PAPER PROCESSING
Abstract
The aim of this paper is to draw attention to the relatively simple way how to both increase fire safety of paper technology processing and to remove one environmentally unfriendly and unhealthy chemical substance from the production process. Practical examination of flammability based on standardized testing method STN ISO 871:2010-07 of selected cellulosic material focusing on harvesting specimens and tissue paper bring new insights into the issues of flammability and combustion of the materials and finished products. There are large quantities of combustible raw materials such as a waste paper, pure pulp cellulose, semi-processed materials including not coloured tissue paper and finished products as paper tissues, toilet paper, paper napkins in the technological process of production and processing of tissue paper. The operations of pulping waste paper with hydrogen peroxide is worked to feed the process and the self-ignition combustion in contact with cellulose material. In practice, the hydrogen peroxide can be replaced by enzyme which is more suitable, fire safer substance thanks to its biologic origin also bio-friendly. Experimental testing is aimed at investigating and determining the impact of bleaching agents as hydrogen peroxide and the enzyme samples in contact with cellulosic materials such as recovered paper, pulp and tissue paper. Comparison of specific fire-technical characteristics of the samples of selected cellulosic material, the flash point and ignition in a hot air oven is presented.
