| titleOfInvention | Production process of corrugated base paper with wood powder fiber adding step and corrugated base paper |
| abstract | The invention belongs to the technical field of corrugated paper, and in particular relates to a production process of corrugated base paper with a step of adding wood powder fibers and the base corrugated paper. Aiming at the problem that the production of corrugated base paper in the prior art cannot take into account both product strength and production cost, the present invention provides a corrugated base paper production process and corrugated base paper with a wood powder fiber adding step, including a wood powder fiber pulping step: adding wood powder 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 stir to obtain the slurry mixture of wood flour fibers, which is then removed by the first high-concentration slag remover and the disc grinding machine in turn. Mixing and decomposing to obtain wood powder fiber slurry, and then adding wood powder fiber slurry to the mixing tank or fluff pulp tower; waste paper slurry production step and papermaking step. In the invention, by adding pulped wood powder fiber to replace a part of raw materials, the production cost is reduced and the corrugated base paper produced has better strength. |
