摘　　要：生活用纸的清洁生产包括纸尘控制和能耗控制两大方面,为此针对性地开发了低温涂层产品替代常规涂层产品,以降低纸尘和蒸汽消耗。本研究主要研究了低温粘缸剂、低温剥离剂和低温涂层的特性。结果表明,低温粘缸剂在较低温度下具有较高的黏结力、合适的耐水性和合适的成膜软硬;低温剥离剂则具有较低的表面张力和适宜的剥离力,纳米级的低温剥离剂可以在涂层中分布得更加均一。通过Turbiscan稳定仪测试低温粘缸剂与低温剥离剂混合液的稳定性,其TSI系数只有0.98,表明混合液稳定。将低温涂层工业化应用后发现,在相同条件下,可以降低80~230 kPa扬克缸蒸汽压力,且能在一定幅度降低蒸汽耗用;较常规涂层而言,低温涂层的应用可以减少10%~50%的原纸/成品的掉粉率。The clean production of tissue included paper dust control and energy consumption control. In order to reduce paper dust and steam consumption,low-temperature coating products were targeted developed to replace conventional coating products. The characteristics of low-temperature adhesive,low-temperature release and low-temperature coating were studied in this paper. The results showed that the low-temperature adhesive had high adhesion,suitable water resistance and suitable film forming hardness at lower temperature. The lowtemperature release had lower surface tension and suitable peel force,and the nano scale low-temperature release could be distributed more evenly in the coating. The stability of the mixture of low-temperature adhesive and low-temperature release was tested by Turbiscan stability instrument. The TSI coefficient was only 0. 98,indicating that the mixture was stable. After industrial application of low-temperature coating,it was found that under the same conditions,the steam pressure of Yankee cylinder could be reduced by 80~230 kPa,and the steam consumption could be reduced to a certain extent. Compared with conventional coating,the application of low-temperature coating could reduce the dust drop rate of base paper/finished products by 10%~50%.
