| 摘要:采用闪急混合工艺使得在最接近流浆箱处向浆料中加入助留剂和施胶化学品等造纸添加剂，并使之迅速和有效地混合。这项多功能混合技术可以做到在同一地点同时将填料、助留剂一起加入到流浆箱中。该工艺操作简单，具有非常短的响应时间，填料留着率更高，纸张性能更优越。由于减少了添加剂在过程中的循环，响应时间非常快速，减少了传统混合过程的水或滤液的量，从而降低了能源消耗，降低了添加剂用量并使工艺过程净化。 |
| Abstract:During the past several years it has been consistently studied and developed concepts to bring filler and different chemicals from thick stock area and from early stage wet-end process closer to the headbox feed area.An immediate and effective mixing with flash mixing process makes it possible to inject papermaking additives e.g. retention aid and sizing chemicals into stock very close to the headbox. The developed versatile mixing technology makes it possible to mix also filler into headbox feed stock simultaneously and together with retention aid agent at the same location. As a result the process is simpler, it has a very short response time, filler retention can be better and sheet properties develop positively. In combination with fast TrumpJet Flash Mixing process targeted results are reduction in consumption of additives, improved efficiency and cleanliness of the process due to reduced circulation of additives in the process, much faster response time and reduced energy consumption together with eliminated use of water or filtrate used conventionally in mixing. Objective is to improve chemistry and process with mechanical means. |
