Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] Such as figure 1 As shown, the present invention provides a preparation process for environmental-friendly linerboard, which is used to prepare waste paper into linerboard. The waste paper includes American waste paper, Hong Kong waste paper and Chinese waste paper. The U.S. waste paper, Hong Kong waste paper The weight ratio of paper and Chinese waste paper is (25%~35%): (10%~20%): (50%~60%), preferably, the waste paper of the United States, Hong Kong waste paper and Chinese waste paper The weight ratio is 30%: 15%: 55%. The preparation process of the environmentally friendly liner boar...

Abstract

A preparation technology of an environment-friendly liner board comprises the steps of breaking waste paper into paper pulp firstly, screening the paper pulp with a coarse screening system, and conveying to a primary classifying screen system to form short fibered pulp; thenperforming secondary classifying screening on slag pulp after primary classifying screening;obatining middle fibered pulp and long fibered pulp, and using the short fibered pulp, the long fibered pulp and the middle fibered pulp for papermaking. According to the preparation technology of the environment-friendly liner board, the waste paper is recycled; the produced liner board is higher in quality; the papermaking cost of an enterprise is effectively reduced; resources are saved; and the damage to an environment is reduced.

Description

technical field [0001] The invention relates to a papermaking process, in particular to a preparation process of an environment-friendly liner board paper. Background technique [0002] Linerboard is a common packaging paper and an important part of packaging paper. In recent years, environmental protection and energy saving have become an inevitable topic in the development of enterprises, especially a problem that enterprises have to pay attention to in the long-term sustainable development. Using waste paper pulp as raw material for products can significantly reduce the cost of enterprises and reduce the damage to the environment. However, in the existing technology, there are still many defects in the papermaking technology using waste paper, and the quality of the linerboard produced cannot be guaranteed. Contents of the invention [0003] Based on this, it is necessary to address the deficiencies in the prior art and provide a preparation process for the environmen...
