| titleOfInvention | The method for recycling paper mill sludge production high-strength cow paper |
| abstract | The invention discloses a kind of methods of recycling paper mill sludge production high-strength cow paper, including waste paper pulp pulping stage, leather fiber slurry pulping stage, sludge slurry pulping stage, wet end is manufactured paper with pulp and whitewashes step of manufacturing paper with pulp, step etc. is squeezed afterwards, wherein, sludge slurry pulping stage includes classification filters pressing sub-step, squeeze pretreatment sub-step, extrusion dehydration and inactivation sub-step, sludge squeezes out sub-step and sub-step with slurry, wet end manufacture paper with pulp and whitewash step of manufacturing paper with pulp includes that waste paper pulp manufactures paper with pulp and forms sub-step, first whitewashing is manufactured paper with pulp sub-step, second whitewashing is manufactured paper with pulp sub-step.The present invention is recycled sludge and produces brown paper, paper mill sludge is set to be regenerated use, and production cleanliness without any pollution, production technology is more energy-saving and environmentally friendly, in the paper making process by gunnite method using sludge slurry as the middle layer of brown paper, new production technology not but not reduces the quality of finished product brown paper that production obtains, and is able to ascend the intensity and toughness of finished product brown paper instead. |
