The Effect of sodium borohydride on alkaline sulfite-anthraquinone pulping of pine (pinus pinea) wood / Esat Gumuskaya in Industrial & engineering chemistry research, Vol. 50 N° 13 (Juillet 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 13 (Juillet 2011) . - pp. 8340-8343 Titre : The Effect of sodium borohydride on alkaline sulfite-anthraquinone pulping of pine (pinus pinea) wood Type de document : texte imprimé Auteurs : Esat Gumuskaya, Auteur ; Emir Erisir, Auteur ; Huseyin Kirci, Auteur Année de publication : 2011 Article en page(s) : pp. 8340-8343 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Wood  Paper  industry  Pulping Résumé : The improvements of adding sodium borohyride to the alkali sulfite-anthraquninone (AS-AQ) pulping process on properties of pulp and paper sheets was investigated. These properties were compared to those of the AS-AQ and the ethanol addition to AS-AQ(ASAE) pulping processes. The screened yield increased with alkali sulfite-antraquinone-sodium borohyride (ASAB) pulping process and kappa number decreased with respect to the AS-AQprocess. Tensile and burst index of paper sheets improved with the ASAB pulping process, and the tear index for the ASAB pulping process was slightly decreased compared to that of the AS-AQ and ASAE pulping processes. It was determined that whiteness and brightness of papersheets decreased by adding sodium borohyride to the AS-AQpulping process, whereas the opacity of papersheets did not change clearly compared to AS-AQ and ASAE pulping processes.
