A production process of high-performance printing paper

Abstract

The invention discloses a technique for manufacturing high-performance printing paper. The technique comprises the steps of conducting defibrination or dissociation on bleached sulfate softwood pulp, mechanical pulp, bleached sulfate hardwood pulp, wet damage stuff and dry damage stuff, then conducting pulp mixing in a mixing pool, conducting mixing with white water in a machine chest, feeding the mixture into a flow box through a fan pump and a pressurized screen, and making the mixture pass through a net section, a pressing section, a front drying section, a sizing section, a rear drying section, a calendering section, a reeling section and a cutting section in sequence to obtain the high-performance printing paper. The technique is simple, clear, continuous and compact in process and suitable for large-scale production of a paper company. The obtained paper is high in stiffness and bulkiness and high in physical strength. Furthermore, due to the reasonable mixture of fibrous materials, the obtained paper is good in evenness, inking is even, color is full and bright, and imaging is clear. The technique can be used for printing colored leaflets and high-end books.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a production process of high-performance printing paper. Background technique [0002] As an important basic raw material industry closely related to the development of the national economy and the construction of human civilization, the paper industry is widely used in printing, packaging, building materials, daily use and other major industries, and most of the paper materials All need to be printed. However, with the diversification of printing methods and printing needs, as well as the improvement of printing and dyeing speed, the grade and quality requirements for printing paper substrates are getting higher and higher. In the process of fiber paper making, the fiber length is often connected by hydrogen bonds, intertwined and deflected to give the paper strength, and the short, small and uniform length of the fiber is conducive to the improvement of paper formation and...

AI Technical Summary

Problems solved by technology

In the process of fiber paper making, the fiber length is often connected by hydrogen bonds, intertwined and deflected to give strength to the paper sheet, and the short, small and uniform fiber is conducive to the improvement of paper formation and further retains the high lignin. Yield pulp fibers are stiff and can increase the bulk of the paper, but the above three are often contradictory and difficult to balance. As a result, the existing printing paper often has difficulties in balancing strength, paper formation and bulk. defect
