Embodiment Construction

[0029] The specific implementation method of the present invention consists of paper pulp production, papermaking, and corrugated cardboard production.

[0030] 1. Pulp production:

[0031] Use water to form pulp from 50% to 80% of the main material and 20% to 50% of the auxiliary material, and the water: (main material + auxiliary material) is 1-2:5-10.

[0032] 2. Papermaking: the above-mentioned pulp is made by conventional corrugated base papermaking process to make corrugated base paper.

[0033] 3 Production of corrugated cardboard: The corrugated base paper made in the second step of papermaking is used to prepare three to seven layers of corrugated cardboard on the corrugated cardboard production line with a mixed adhesive glue. The performance indicators of the five-layer cabinet are as follows:

[0034] Compression resistance of empty box: ≥25KN;

[0035] Edge pressure strength: ≥26KN / m;

[0036] Bursting strength: ≥5000Kpa;

[0037] Puncture strength: ≥35J.

Abstract

The invention discloses a formula for sludge corrugated base paper, which consists of major ingredient and accessory, wherein the major ingredient is papermaking waste water sludge; and the accessory is mixing superfine padding formed by mixing inorganic superfine padding and organic superfine padding. The invention further provides a production process for producing corrugated base paper by the formula for sludge corrugated base paper, as well asprovides sludge corrugated base paper and case board paper prepared by the invention and a corrugated board made of adhesives. The papermaking waste water sludge is directly used as papermaking raw materials to be recycled and manufactured into recycled paper, so that the invention can solve the problem of secondary environment pollution caused by papermaking sludge; the solid wastes of the papermaking waste water sludge can be recycled; and the produced corrugated board has better strength and waterproof property.

Description

Technical field [0001] The invention relates to a formula of sludge corrugated base paper, a production process for producing sludge corrugated base paper using the formula, and a corrugated board produced by using the sludge corrugated base paper. Background technique [0002] As we all know, the paper industry is an important industry in the national economy, but it is also a polluting industry. Thousands of paper mills across the country have an annual output of more than 30 million tons of various paper and paperboards, which also produce nearly 20 billion tons of chemical oxygen demand (CODcr) each year at 1500-2000mg / L papermaking wastewater and papermaking wastewater sludge They pose a great hazard to the environmental protection of water sources, air, and farmland. Among them, the treatment of papermaking wastewater and sludge has become the most difficult problem. At present, the usual treatment method at home and abroad is to use a plate and frame filter to filter the w...
