| titleOfInvention | Corrugated base paper production process with wood flour fiber addition step and corrugated base paper |
| abstract | The invention belongs to the technical field of corrugated paper, and in particular relates to a corrugated base paper production process and corrugated base paper with the step of adding wood flour fibers. Aiming at the problem that the production of corrugated base paper in the prior art cannot take into account the product strength and production cost, the present invention provides a corrugated base paper production process and corrugated base paper with a wood flour fiber adding step, including a wood flour fiber pulping step: wood flour raw material It is transported to the first pulping and stirring equipment through the first conveying mechanism, and water is added to the first pulping and stirring equipment to obtain a pulp mixture of wood flour fibers, which is then sequentially removed by the first high-concentration slag remover and a disc mill. Mixing and dispersing to obtain wood flour fiber pulp, and then adding the wood flour fiber pulp into the mixing pulp tank or the fluff pulp tower; waste paper pulp production steps and papermaking steps. In the present invention, the pulped wood flour fiber is added to replace a part of the raw material, so that the production cost is reduced and the corrugated base paper obtained has good strength. |
