| Abstract:Using nanofibrillated cellulose (NFC) as natural polymer additives， mixed with pulp， the shell-formed full-fiber paper-based dust suppressant with excellent performances was prepared by optimizing the dosage of NFC and spraying quantity of paper-based dust suppressant. The applicability of it was discussed by comprehensive morphology characterization， seed germination experiment， and outdoor field experiment. The results showed that when the dosage of NFC (relative to the mass of adiabatic pulp) was 6%， the paper-based dust suppressant was sprayed on the sand surface (spraying quantity of 5 L/m2)， which could form a dense and high-strength fiber film shell. Compared with the paper-based dust suppressant without NFC， the compressive property of the film shell increased from 510 kPa to 1 470 kPa. The wind resistance was significantly improved， and the sand loss rate was decreased from 32.8% to almost 0 (sand loss rate of 0.41%). The rain erosion resistance was increased from 78.1% to 90.3%. The anti-evaporation performance was more excellent， and the water evaporation rate was significantly reduced. Adding NFC to the paper-based dust suppressant could promote the formation of a denser film shell microstructure， thereby enhancing the bonding strength between pulp fibers and improving the performances of the paper-based dust suppressant. The film shell formed by the paper-based dust suppressant could achieve the effect of long-term suppression of dust pollution， and had no effect on plant seed germination and seedling growth. |
