Fireproof Paper Production from Turkish Red Pine (Pinus brutia Ten.) with Using Fire Retardants
Öz
Abstract
Aim of study: It was our aim to produce fireproof papers from Turkish Red Pine (Pinus brutia Ten.) using eco-friendly pulping method and fire retardant chemicals (FR).
Area of study: This work was carried out in Kahramanmaraş Sütçü Imam University, Faculty of Forestry, Pulp and Paper Production Laboratory.
Material and Methods: Three different pulping trials were carried out with soda-anthraquinone method (AQ) and the kappa numbers, viscosities, yields, and optical and physical properties of the pulps were determined in order to find out the optimum cooking condition. Borax (BX), boric acid (BA), alpha-x (AX), and ammonium polyphosphate (APP) were used as FR in certain rates (3, 6, 9%). FR applied papers were subjected to combustion test and the fire properties of the papers were determined as combustion rate.
Main results: The results indicated that addition of AQ to cooking liquor increased the pulp yield about 4.6%. Also, the kappa numbers of the pulps were decreased by adding AQ from 120 to 50. AQ addition had significantly effects on the physical properties of the paper. The best results in fire properties were obtained from BX (6%, 9%), BA (6%, 9%), and AX (9%), respectively.
Research highlights: Considering paper is a flammable material, increasing the fire resistance of papers is needed. In addition, production using environmentally friendly methods is required in the world where population and technology are increasing rapidly.
