Stone water-free paper-making method and flow

Abstract

The invention relates to a stone water-free paper-making method and a flow thereof; the process method and the flow are that: after inorganic material is dried, a modifier is added in the inorganic material to carry out mixing modification in mixing / modifying equipment, and then the inorganic material which is activated and modified and organic material and accessory ingredients are mixed and are conveyed to the modifying equipment to carry out secondary modifying treatment (banburying), and then extrusion granulation is carried out to form granulated raw material, and the granulated raw material is conveyed to raw material drying equipment to carry out secondary drying by raw material conveying equipment, and the dried raw material is directly conveyed to a film casting and laminating machine and a drawing mill to be produced into body paper, and then the body paper is cut and rolled for spare, and the cut rim charge is recycled; corona treatment is carried out to the body paper, and then surface coating treatment is carried out in a coating machine, so as to obtain coated paper; by adopting the method to produce stone paper, the production speed is rapid, the output is high, the flatness and smooth finish of the finished paper are good, the product quality is high, and various printing modes and printing inks are suitable for the paper. The process in the invention is simple and rational, the product quality is stable and the effect is good.

Description

Technical field

[0001] The invention relates to a paper production method and process, in particular to a stone waterless papermaking method and process, and belongs to the technical field of synthetic paper production. Background technique

[0002] Paper and cardboard products are indispensable consumer goods in people's lives. At present, the production of paper mainly uses fiber resources such as wood to produce pulp through physical and chemical methods, and further processing to obtain paper and cardboard products. This generally includes a variety of chemical treatment and mechanical treatment processes, which not only require a large amount of energy and water resources, but also cause serious pollution such as waste water and waste gas. For example, chemical pulping requires raw material washing, cooking, bleaching, etc., while papermaking requires adding various chemicals for pulping, streaming, drying, etc., and sometimes chemicals are needed for surface coating.
