Production method for ultra-low quantitative corrugated core paper and product produced thereby

Abstract

The invention discloses a production method for making regeneration corrugated core paper of a micro-corrugated cardboard and a product produced thereby. The production method comprises the following steps of: 1) proportioning raw materials; 2) processing waste paper, namely sending mixed waste paper to a hydraulic pulp kneader, and then sequentially subjecting to a high-concentration desander, a coarse screen, a heavy-quality desander, a fine screen, a multi-disc thickener, a heat dispersion system, a disc mill and a pulp pool; and 3) making paper sheets, namely subjecting pulp to fore pool, a pulp washing pump, a net front screen, a dilution water pulp box, a clamping net forming device, a four-roller three-press area provided with shoe press, a drying part, a paper winding machine and a rewinder, and storing finished products in a cabin. The physics index of the ultra-low quantitative corrugated core paper produced by the method can meet the quality standard of body paper for making the micro-corrugated cardboard; as the ultra-low quantitative corrugated core paper is ultra-low quantitative, the micro-corrugated cardboard below G-corrugation can be made; meanwhile, the yield rate of cartons can be greatly improved, the production cost of the cartons is reduced, and an effect of environment protection and energy saving is further achieved.

Description

technical field [0001] The invention relates to a production method of recycled corrugated medium paper for manufacturing micro-corrugated cardboard, and also relates to the corrugated medium paper produced by the method, belonging to the technical field of recycled paper manufacturing in the papermaking industry. Background technique [0002] The corrugated corrugated types are arranged in English alphabets in order of size: D, K, A, C, B, E, F, G, N, O. From E to O, they are collectively called micro-corrugated. Since the advent of micro-corrugated in 1990, the market utilization rate has been increasing, and the United States has grown at a rate of 2% per year. my country's micro-corrugated cardboard started in 2006, because of its good printability (direct offset printing), high strength, low weight and other characteristics, it has huge market development potential. In recent years, micro-wale cardboard has been devouring the market of cardboard and ordinary corrugated...

Problems solved by technology

The lower and lower flute heights require the production of micro-tile base paper to ensure the strength and quality of the base paper is getting lower and lower. At present, my country's micro-tile face paper mostly uses 200g / m 2 For the above light-weight coated white board paper, the corrugated layer is mostly 90g / m 2 For the above corrugated base paper, it is difficult to manufacture G flute, N flute and O flute micro-corrugated with low flute height by using the base paper in this quantitative range. Therefore, reducing the ration of the micro-corrugated base paper under the premise of ensuring quality is the primary problem to be solved.
