High-gloss high-strength low-weight construction template base paper production process
2015
A high-gloss high-strength low-weight construction template paper production process, comprising the steps of: with pulp: The deinked pulp, unbleached mechanical aspen pulp mass ratio of 70-80%: 20-30% unbleached Yang wood pulp with a mechanical pulp, and high wet strength agent was added in accordance with slurry process 20-30kg / ton of dry pulp; said waste paper deinking pulp preparation process is as follows: # 8 through US waste drum pulper removing large impurities, through complex and high concentration desander coarse screening system to remove greater weight impurities, and then through the low-concentration desander lower weight impurities removed, after flotation deinking to remove part of the ink, i.e., Ltd. deinked pulp into high strength; papermaking: step (1) directly through the formulated slurry headbox Internet shaped into paper, and then calendered by a calender to a high temperature pressurized closed. The present invention has simple process, building templates produced paper with good smoothness, high strength, low weight and high bulk advantages.
