提高再造烟叶网部留着率的研究

A study on ascending the wire part retention rate of reconstituted tobacco leaf

对提升再造烟叶网部留着率进行了研究,结果表明:(1)不同湿重浆料留着率由高至低依次为5.5>4.5>5.0>5.3>4.8,湿重5.5g时浆料留着率最高为62.51%。(2)使用改进后的成形板,网部留着率提升至73.49%。(3)总压148mmH_2O、唇口开度11.5mm、摆振转速300r/min时,留着率最大。根据极差分析影响留着率从大到小的参数为摆振转速>唇口开度>流浆箱总压。(4)使用某品牌新助剂,对应的白水浓度、留着率有相应的提高,网部留着率可达64.67%。在助剂添加比例0.2%时,网部留着率最高为61.4%;在助剂添加比例0.18%时,填料留着率最高为83.2%。

The research of ascending the retention in wire part of reconstituted tobacco leaf was studied in this paper. The results show as follows：（1） the order of different pulp with different wet weight from high to low ranks as 5.5〉4.5〉5.0〉5.3〉4.8, the highest wire part retention is 62.51% when the wet weight is 5.5g;（2） the wire part retention increases to 73.49% when use of improved forming board;（3） the wire part retention is the highest when the total pressure is 148 mmH2O column, the opening of the head box lip is 11.5 mm, the shaking speed is 300r/min;（4） by using some brand new additives, the corresponding water concentration and the wire part retention have a corresponding increase, even the wire part retention is 64.67%. The highest retention rate in wire part keeps up to 61.4% when additives is added by 0.2%, the highest fi ller retention reaches up to 83.2% when additives added by 0.18%.
