Jan 3, 2021 · The pulping industry has for decades not developed new pulping techniques but rather improved the traditional chemical and mechanical pulping processes to enhance pulp yields and quality, as well as saving energy and chemical loading required for pulping.
Sep 23, 2024 · Pulping is the process of using chemical or mechanical methods, or a combination of both, to dissociate plant fiber raw materials into natural pulp (unbleached pulp) or bleached pulp. The main function of pulping is to provide high-quality pulp for papermaking and other fiber processing industries.
Nov 20, 2023 · In this review, some of the materials employed in pulping are outlined, and the fiber content, pulping method, as well as the strength of wood and non-wood crop straw as pulping raw materials are analyzed and discussed.
Pulping is a process of converting lignocellulosic materials into pulp. Pulp is an intermediate material applied in papermaking. There are huge numbers of technologies of pulping methods that can be generally divided into three categories: mechanical (MP), chemical (CP), and hybrid pulping (HP).
May 1, 2020 · In this paper, we present a review of pulping technologies to convert logs or wood chips and non-woody materials into pulp for use in papermaking which consist of mechanical, chemical and semi-mechanical.

Papermaking - Pulping, Refining, Bleaching: Mechanical or groundwood pulp is made by subjecting wood to an abrading action, either by pressing the wood against a revolving grinding stone or by passing chips through a mill. The wood fibres are separated and, to a considerable degree, fragmented.
Nov 5, 2018 · The pulping method is a new type of non-polluting pulping technology, which is mostly used in the straw pulping process. This technology exploits the synergistic action of oxygen and alkali to eliminate the contaminated exhaust gases during cooking process.
