[0002] Corrugated box is the most widely used packaging product. It has the characteristics of lightness, firmness, vibration reduction and suitability for mechanized production. It has been used in transportation packaging and sales packaging for many years, especially when countries in the world attach great importance to environmental protection. Next, corrugated boxes have the advantages of recycling and reuse, which are beneficial to environmental protection, loading and unloading, and saving wood, etc.; while traditional corrugated boxes have certain disadvantages in use. Traditional corrugated boxes are due to low compressive strength during storage and stacking. , so that the cartons will be deformed when stacked and stored, and the corrugated boxes will be dumped, resulting in damage to the items stored in the corrugated boxes. At the same time, the traditional corrugated boxes are not easy to use in a humid environment, and the moisture-proof effect is not ideal. Therefore, we propose an energy-saving production process for high-quantity and high-strength corrugated boxes

Abstract

The invention discloses an energy-saving production process of high-quantitative high-strength corrugated cartons. The energy-saving production process of high-quantitative high-strength corrugated cartons comprises the following steps: first, preparing paper pulp, namely, soaking collected waste cardboard boxes, waste magazines and old newspapers in water for 20-24 hours, putting the soaked waste cardboard boxes, waste magazines and old newspapers into a pulverizer to be minced, and removing impurities, slag and crude fibers, so that the fiber length in the remaining fiber pulp is 1.0-1.5 mm, the pulp is for later use, and thus the screened fiber pulp is obtained; and second, carrying out pulping and pulp mixing treatment, namely, pulping the fiber pulp, wherein the pulping degree is controlled to be 20 degrees SR to 30 degrees SR, the humidity is controlled to be 3 g to 5 g, then carrying out pulp mixing, so that evenly mixed pulp is obtained, and carrying out standing for 120 min to 150 min, wherein the concentration of the pulp is controlled to be 1.0% to 1.5%, and thus the pulp for preparing paper is obtained. According to the energy-saving production process of high-quantitative high-strength corrugated cartons, through enhancement treatment and gluing treatment, the structural strength and compressive strength of the corrugated cartons are greatly improved, and meanwhile, the service lives of the corrugated cartons are prolonged.
