Background

Paper and paperboard play an important role in many fields of politics, economy, culture and the like in one country, and are also indispensable daily consumer goods in daily life of people. However, paper making is an industry with large investment, high energy consumption, serious pollution and large raw material consumption. Therefore, the development of current and future process technologies and equipment in the paper industry mainly aims at reducing pollution, saving energy, fully utilizing fiber resources and the like. High strength, high yield, high whiteness, low pollution are the key points of pulping technology, and high quality, low basis weight and low consumption are the key points of papermaking technology. Currently, the internationally more advanced cooking processes and equipment are the norwegian modified continuous digester and isothermal digester. They are characterized in that the kappa number of the brown stock after cooking is low (up to 25) without reducing the strength of the pulp. In the aspect of intermittent cooking, the cold blowing technology is more prominent. Its advantages are less energy consumption, high yield of paper pulp and high cooking power. From the development situation, the cooking technology develops and applies the deep cooking technology on the basis of expanding and improving the sulfate cooking, reduces the kappa number of the brown stock, reduces the energy consumption and reduces the pollution. Sulphur-free pulping will also be a direction for future development. In recent years, the new technology adopted in the world is the chlorine-free bleaching technology (ECF technology for short), and the totally chlorine-free bleaching technology (TCF technology for short) has been gradually applied. Compared with the traditional method, the two bleaching methods have the greatest advantage of greatly reducing environmental pollution. For the conventional chlorine bleaching, the content of AOX in the wastewater is 2.4 kg/ton pulp, while the content of AOX in the wastewater is 0.6 kg/ton pulp and 0.2 kg/ton pulp by ECF technology and TCF technology, respectively, for the introduction of the paper making process, the journal: chenkefu, an engineering technology for exploring future development in the papermaking field, china paper industry 2019(07), however, certain problems still exist in the current papermaking process, and the method specifically comprises the following aspects:
