Pulp and paper
Effect of Alkali Oxidation of fiber on characteristic of virgin and recycled pulp

Omid Esmailiey; Esmaeil Rasooly Garmaroody; Rahman Jafari petroudi

Volume 38, Issue 4 , December 2023, , Pages 316-329

https://doi.org/10.22092/ijwpr.2023.363900.1763

Abstract
  Background and purpose: In the production of pulp, materials such as sodium hypochlorite, chlorine dioxide, ozone, hydrogen peroxide, etc. are used in the bleaching process.  In addition, the above-mentioned materials can be used as oxidizing materials to increase the surface charge of fibers, can ...  Read More

P pulp bleaching whit hydrogen peroxide and sodium hypochlorite

khadijeh armand; ali ghasemiyan

Volume 35, Issue 1 , April 2020, , Pages 11-21

https://doi.org/10.22092/ijwpr.2020.128739.1587

Abstract
  In this research, the effect of sodium peroxide and sodium hypochlorite on the chemical-mechanical pulp bleaching (CMP) has been investigated. For this purpose, unbleached CMP pulp was produced from Mazandaran wood and paper mill, and bleaching with hydrogen peroxide and sodium hypochlorite was carried ...  Read More

The effect of heat ageing on color change and optical properties of bleached Chemi-Mechanical Pulp (CMP) with One and Two-stage of Sodium Hypochlorite and Hydrogen Peroxide

ghasem asadpour; fatemeh rajabi; seyed majid zabizadeh

Volume 33, Issue 4 , February 2019, , Pages 467-477

https://doi.org/10.22092/ijwpr.2018.121555.1471

Abstract
  High yield and chemi-Mechanical pulps are susceptible to oxidation-optical and thermal reactions. These reactions result discoloration and brightness reversion in pulps. In this research, chemi-mechanical pulps were selected randomly from Mazandaran pulp and paper mill and were bleached separately by ...  Read More

Ramin Vaysi; Mohammad reza Salimifar

Volume 32, Issue 3 , September 2017, , Pages 311-321

https://doi.org/10.22092/ijwpr.2017.105625.1330

Abstract
  This study and it aim was accomplished on the effect of TCF bleaching on optical and mechanical properties of CMP pulp. For this purpose, some unbleached CMP pulps were randomly selected from Mazandaran Wood and Paper Industries (MWPI). Then these pulps were bleached with two and three OP, OPY, PY and ...  Read More

Effects of oxidized recycled fibers on paper properties

Mania Jadidi; Noraldin Neghad; Majid Zabihzadeh

Volume 27, Issue 3 , September 2012, , Pages 409-422

https://doi.org/10.22092/ijwpr.2012.116105

Abstract
  This research was conducted to find a procedure to increase the optical and strength properties of papers made from oxidized waste newspaper fibers. Samples of waste newspapers were randomly selected and deinked, then one part of deinked pulp was refined.  Both refined and unrefined recycled pulp ...  Read More

The effect of consistency on the optical properties of hydrogen peroxide bleached CMP pulp

Somayeh Ghasemi; Rabie Behroz

Volume 26, Issue 2 , June 2011, , Pages 298-409

https://doi.org/10.22092/ijwpr.2011.117196

Abstract
  Using high consistency pulp especially in bleaching plant is highly attractive due to considerable reduction in energy and water consumptions and low effluent volume. This research investigates the effect of consistency CMP pulp on bleaching by hydrogen peroxide. For this purpose, unbleached mixed hardwood ...  Read More
