| Abstract: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 low-temperature 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%. |
